[0035] It is appreciated that the present invention provides several embodiments of a self-ligating orthodontic bracket assembly that includes a bracket and locking clamp (s). The bracket has a closed position in which the clamp inhibits access to a crack in the orthodontic wire and an open position in which the clamp allows access to the groove in the orthodontic wire.
[0036] In general, the illustrated bracket includes a body and a base. The body may include the crack of the orthodontic wire (two receiving areas positioned mesially and distally from the bracket body), a first loop fin (for example, gingival loop fin (s)), a second loop fin (for example , occlusal strap fin (s), and a region between the fins that extends gingival-occlusally across the body and can generally be defined by at least one of the side spacers or a bridge portion of the gingival strap fins and the side spacer or a bridge portion of the occlusal strapping fins. The base connects the bracket to a tooth and may include a fixing portion that defines a pattern, which receives an adhesive and is formed to affix to the tooth. In a specific embodiment, the lingual side of the fixation portion attaches to the labial side of the tooth. In formation, the base can be connected to the body with welds. In other formations, the base can be fixed in other ways or formed in a single part with the body.
[0037] Referring now to FIGS. 1A to 1F, a self-ligating orthodontic bracket is shown and is generally indicated by reference number 1010. FIG. 1A is a perspective view of a self-ligating dental bracket in a closed position according to the present invention with a lateral spacing between the gingival strap fins and a lip portion (for example, hook portion) that extends from the respective flap fins. mesial and distal gingival binding to form the reception areas. The labial portions that extend outwardly from the mesial and distal sides of the body to receive a flap portion (for example, a pitchfork) of the clamp. The labial free end of the clamp (e.g., gingival tip portion) includes the flap portions of the clamp, which can be deformed to fit the contour of the receiving area below the hook portions of the gingival fin fins.
[0038] More particularly, the orthodontic bracket 1000 includes a body 1012 and a lingual support base 1014 attached to the body. The mounting base 1014 has a lingual surface to be attached to a tooth. In general, body 1012 defines a square, rectangle or otherwise formed member. However, it is appreciated that the body 1012 can be defined through various other formed configurations such as a rhombus shape, a circular shape, an oval shape, or an otherwise formed member.
[0039] A pair of laterally spaced gingival fin fins 1016 and a pair of laterally spaced occlusal ligation fins 1018 extend from the lip surface of the body 1012. The gingival ligament fins 1016 and occlusal securing fins 1018 generally curve lingually. A region between the 1024 fins extends gingival-occlusally through the body 1012 and can generally be defined by the lateral spacing of the gingival fin 1016 and / or the lateral spacing of the 1018 occlusal fin fin. The region between the 1024 fins can be an open passage (for example, unobstructed) or it can be a closed passage (partially or completely obstructed) FIGS. 1A-1 F, or different. A gap in the orthodontic wire 1020 extends mesial-distally through the body 1012 and between the gingival and occlusal loops at 1016 and 1018. The gap in the orthodontic wire 1020 opens labially to receive an orthodontic wire (not shown), The gap in the orthodontic wire 1020 can be interrupted in the region between the fins 24 of the body.
[0040] The bracket 1010 may also include a locking mechanism that includes a locking clip 1026 to hold the orthodontic wire in the 1020 orthodontic wire slot while in the closed position. This locking clamp 1026 is structured in a substantially U-shaped transverse configuration, and one side of it is formed as a lingual free end 1028 (a portion located on the side of the tongue) located on the base side and extending along the base (through an opening formed between the body 1012 and the base 1014), while the other side of it is formed as a labial free end 1030 having substantially the same width as the length of the orthodontic wire 1020 and extending over the upper side of the slot. The lingual free end 1028 and the labial free end 1030 can be interconnected by a curved portion 1032.
[0041] The locking clip 1026 can be formed of an elastic member in which a notched portion 1034 is substantially provided in the center of a binding end portion of the lip free end 1030 (a portion located on the lip side). The notch portion 1034 can be defined by the left and right (e.g., mesial and distal) flap portions 1031 of the portion opposite the base 1028, which is the top T-shaped or Y-shaped portion in the substantially T-shaped configuration. or Y of the locking clip 1026.
[0042] In addition, since the notched portion 1034 of the locking clamp can be correspondingly provided for the width of the bracket body (for example, free / open mesial / distal end portions) so as to fit this, the displacement and twisting of the flap portions of the locking clip 1026 in the longitudinal direction of the groove can be effectively inhibited. Namely, with respect to the displacement and twisting of the securing portion of the locking clamp 1026 in the longitudinal direction of the body, such displacement can be inhibited by a receiving area provided via a mesial side and / or a distal side of the body. bracket 1012.
[0043] The receiving area can be defined by a receiving member 1036 extending from the free / open external end of the bracket body 1012. Preferably, the free / open external end of the bracket body is generally coplanar with the ends mesial / distal free of the 1020 orthodontic wire slit, although not necessary. In a specific example as shown in FIGS 1A-1F, the receiving member 1036 may include lip hook portions 1038 that extend mesially / distally from the free / open outer end of the gingival fin fin 1016 of the bracket body 1012. The portion lip hook can be provided to stop one end of the locking clip 1026 (e.g., tabs 1031) in a hook position on a free / open end portion of the bracket body. More particularly, a portion of mesial labial hook 1039 may mesially extend from the mesial free / open end portion of the bracket body (e.g., mesially extending from the mesial gingival fin fin) and a portion of distal labial hook 1038b may extend distally from a distal free / open end portion of the bracket body (for example, extending distally from the distal gingival fins). Desirably, the lip hook portions 1039 and 1038b prevent the orthodontic wire from being unintentionally removed from the slot of the orthodontic wire 1020 by limiting the lip movement of the locking clamp 1026 while in the closed position.
[0044] Locking clamp 1026 may also include an engagement end portion 1040, which may be formed by a notched portion, a recessed portion, a projection, or the like. The engagement end portion can be formed into a rear end portion of the lingual free end 1028 on the locking clip 1026. The engagement end portion 1040 can be configured to assist in the movement of the locking clip 1026 from the closed position to a open position through contact by a tool or otherwise. For example, a tool may come into contact with the engaging end portion so that the lingual free end 1028 moves occlusally, thereby moving the labial free end 1030 occlusally away from the hook portions 1039 and 1038b to a open stop groove 1042 near the lip surface of the occlusal yoke fins 1018 so that the locking clip 1026 can be latched in the open position.
[0045] When included, the open stop groove 1042 can be provided in the region between the fins 1024 connecting the occlusal anchoring fins between them. In addition, the open stop groove 1042 can include a mesial-distal protuberance 1044, which does what The open stop groove 1042 can also include a mesial-distal depression 1046 having distal and mesial end walls 1048. The depression 1046 having substantially the same width as the curved portion 1032 of the locking clip 1026 so that the end walls 1048 can minimize the mesial-distal displacement of the locking clip 1026 resulting from an unexpected force that is applied to the bracket. Optionally, the inner walls 1050 of the occlusal lashing fins can also minimize the mesial-distal displacement of the locking clip 1026 resulting from an unexpected force being applied to the bracket in addition to or in place of the depression 1046 (desirably, a locking clip having a curved portion with a width corresponding to the width of the region between the fins between the occlusal strapping fins).
[0046] FIGS. 2A-2C are various views of an alternative embodiment of a self-ligating bracket shown in FIG. 1A. As such, the present invention can provide a self-ligating bracket 1010a having a bracket body 1012a, a base 1014, a locking clip 1026 and a bridge portion 1052a in the gingival region between the fins 1024a in order to connect the mesial inner side of the distal gingival fin with the distal inner side of the mesial gingival fin. Optionally, the bridge portion 1052a can include a depression 1054a having an opening 1056a to allow access to a dental tool to assist in opening and / or closing the bracket 1010a.
[0047] FIGS. 3A-3E are various views of another alternative embodiment of the self-ligating bracket shown in FIG. 2A wherein the present invention may include a self-ligating bracket 1010b having a bracket body 1012b, a base 1014, a locking clip 1026b and a receiving member 1036b. The receiving member may also include at least one 1058b lingual border. The lingual edges 1058b can be provided as separate artifacts that extend mesially and distally from the respective sides of the body 1012b in a location lingually spaced from the hook portions 1038b. The lingual edges 1058b can be configured to minimize and / or substantially prevent the lingual movement of the locking clip 1026b. In this specific example, the hook portions 1038b have been reduced / tuned (gingival-occlusally) and the gingival ties of the clip flap portions can be slightly curved on the lips for increased interactivity. In addition, the curved portion 1032b of the locking clip 1026b may include a through hole 1060b, which corresponds to a depression 1046b of the open stop groove 1042b to allow access to a dental tool to assist in opening and / or closing the bracket 1010b.
[0048] The bracket 1010b may also include an alternative locking mechanism having a modified lingual free end of the locking clip being received by the lingual opening of the bracket. More particularly, the locking clamp 1026b can include a free lingual end 1028b having a plurality of deformable fingers spaced 1062b for engagement with a lingual opening 1064b formed in an occlusal portion of the body. The deformable fingers 1062b having mesial / distal flange portions that extend outward 1066b at a free gingival end. The lingual opening 1064b that extends into a cavity 1068b having a width greater than the width of the lingual opening 1064b to prevent deformable fingers from passing through the lingual opening (while in a non-stressed state) and separating from the clamp. Desirably, the deformable fingers 1062b are deformed in relation to each other, such that the width between the outer ends of the flange portion is less than the lingual opening 1064b so that the lingual free end 1028b of the locking clip 1026b can be inserted through the lingual opening 1064b and in the lingual cavity 1068b to protect itself in this. Once the free lingual end of the locking clip is received within the lingual cavity, the deformable fingers substantially return to their unstressed state / position. Optionally, once received in the lingual cavity, the deformable fingers can remain in a partially stressed state due to the active engagement of the outer edges 1070b of the flange portions with the respective mesial and distal side walls 1072b of the lingual cavity to assist in inhibiting movement ( for example, sprain, mesial-distal movement, and / or other).
[0049] FIGS. 4A-4D are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 3A-3E where the receiving member 1036c can also include end walls 1074c interconnecting the lip hooks 1038c and lingual edges 1058c to define a perimeter around a through hole 1076c in the receiving areas to cover and protect the flap portions mesial and distal 1031c of the locking clip 1026c while in the closed position. As in FIGS. 3A-3E, the gingival strap fins 1016c have been reduced / fine-tuned (gingival-occlusally) and the gingival strapping of the flap portions 1031c can be slightly curved on the lip for improved interactivity. In addition, the width of the notched portion 1034c in the flap portions 1031c can be correspondingly provided to adjust the width of the bracket body 1012c to inhibit displacement and / or twisting of the locking clip 1026c while in the closed position.
[0050] FIGS. 5A-5F are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 3A-3E where the receiving member 1036d may also include a separate artifact as a mesial-distal extension 1078d to the gingival ligament fins 1016d. The mesial-distal extensions 1078d being configured to interconnect the lip hook portions 1038d with the respective lingual edges 1058d in the form of a "cup c" to retain the flap portions 1031d of the locking clip 1026d while in the closed position.
[0051] FIG. 5E is a cross-sectional view of the self-ligating dental bracket in FIG 5A, which also illustrates a depression / chamfer 1046d in the open stop groove 1042d of the body 1012d between the occlusal ligation fins 1018d to guide a standard dental instrument to facilitate the opening of the dental clip. locking 1026d.
[0052] FIGS. 6A-6C are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 5A-5E in which an alternative locking mechanism can be provided. The alternate locking mechanism may include ratchet portions 1080e close to the respective side walls 1072e (for example, mesial and distal side walls) of the lingual cavity 1068e to substantially hold each flange portion 1066e of the lingual free end 1028e of the locking clamp 1026c in a generally predetermined position 1082e and / or area of the lingual cavity 1068e while in the closed position. Ratchet portions 1080e may also include tapered occlusal end portions 1084e to facilitate movement from the free lingual end 1028e to the predetermined (gingival) area 1082e of the lingual cavity.
[0053] FIG. 6B is a cross-sectional view of an alternative embodiment of the body and clamp of a self-ligating dental bracket shown in FIG. 5E where the clamp slides gingivally to the open position before the lingual free end of the clamp rotates slightly on the lip in the almost open position.
[0054] FIG. 6C is a bottom view of the body and clamp in FIG. 6A in which the lingual free end of the locking clip securely locks in the closed position. When the clamp slides gingivally into the open position, the free lingual end of the clamp will be guided by the tapered opening in the lingual portion of the body.
[0055] FIG. 6E is a perspective view of the locking clip 1026e and may also include at least one groove 1086e extending (e.g., labially-lingually) close to the curved portion 1032e. In a specific example, locking clip 1026e includes a pair of grooves that extend labially-lingually 1086e, although not required. Slots 1086e can provide additional reinforcement to the locking clip 1026e to inhibit the displacement and / or twisting of the locking clip 1026e while in the closed position. THAT'S TRUE
[0056] FIGS. 7A-7C are various views of another alternative embodiment of the self-ligating bracket shown in which the receiving member 1036f can include complete hook portions 1038f similar to the alternative embodiment shown in FIGS. 1A (for example, not having a reduction in thickness) while also including the 1058f lingual edges. In this specific embodiment, the gingival strapping portions 1033f of the flap portions 1031f can generally remain flat.
[0057] FIGS. 8A-8E are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 4A-4D wherein the receiving member 1036g may also include complete hook portions 1038g which extend from the respective gingival strap fins 1016g thereby providing an enlarged lip surface 1088g close to the gingival strap fins 1016g. In doing so, the hook portions 1019g of the gingival strap fins 1018g may extend lingually, covering at least partially the gingival side of the through hole 1076g1.
[0058] FIGS. 9A-9H are various views of another embodiment of the self-ligating bracket of the present invention in which the bracket 1010h includes a modified locking clamp 1026h and a modified receiving member 1036h. In this specific embodiment, the receiving member 1036h may be centrally located close to the bracket body 1012h and may include a continuous retention channel (e.g., latent) 1090h to allow a positive seat to retain the locking clamp 1026h. Desirably, the retention channel 1090h generally extends in a parallel manner with respect to the groove of the orthodontic wire 1020h between the respective mesial and distal sides of the bracket body 1012h. In this specific embodiment, the width of the locking clamp 1026h at the labial free end 1030h may have been reduced, in general, to the same mesial-distal width of the bracket body 1012h. In addition, the labial free end 1030a of the locking clip 1026h may include a single flap portion 1031h (e.g., generally free of a notch), which generally corresponds with the retention channel 1090h. The retention channel can also be defined by a generally c-shaped profile to not only provide a positive seat (and limit the lingual movement of the free labial end 1030h), but can also provide a hook portion 1038h to limit the lip movement of the free labial end 1030h while in the closed position. Optionally, the height (for example, labial-lingual height) of the 1090h retention channel can be sufficiently measured (for example, less than or equal to the thickness of the orthodontic wire) so that obstruction of the orthodontic wire in it can be substantially prevented while the free end portion 1030h of the locking clip 1026h is in the closed position.
[0059] FIG. 9F is a gingival view of the self-ligating 1010h dental bracket shown in FIG. 9A incorporating a 1064h lingual opening (e.g., through hole), which is a continuous channel that extends between the gingival ribbed fins 1016h and the occlusal binding ribs 1018h to the lingual portion of the body to facilitate calculus cleaning / tartar retained.
[0060] FIG. 9G is a bottom view of the body 1012h and locking clamp 1026h of a self-ligating dental bracket shown in FIG. 9A while in a closed position with the base removed. In this specific embodiment, the lingual opening 1064h extends completely through the lingual portion of the body 1012h (as disclosed above) while the area of the lingual cavity 1068h has been reduced.
[0061] FIGS. 10A-10B, 10C-10D, 11A-11C, 12A-12C, 13A-13C, 14A-14C, 15A-15C, and 16A-16C are various views of alternative locking mechanisms of the self-bonding dental brackets of the present invention.
[0062] FIGS. 10A-10D are various views of an alternative embodiment of the self-ligating dental bracket shown in FIGS. 9G- 9H in which the 1068m lingual cavity has.
[0063] FIGS. 10A-10B provide the self-ligating bracket 1010i, which can include a modified locking arrangement having a locking clip 1026i and a lingual cavity 1068i having a centrally located stabilizing member with locking grooves / ratchets to facilitate and securely lock the end free lingual of the locking clamp in both the open and closed position. In this specific embodiment, the locking clamp 1026i includes a Y-shaped / U-shaped lingual free end 1028i having deformable fingers 1062i. The 1062i deformable fingers can include 1066i internally extending flange portions that are configured to actively engage the grooves in the open position 1094i (to assist in maintaining the bracket in the open position) or grooves in the closed position 1096i (to assist in maintaining the bracket in the closed position) of a 1098i stabilizing member. The stabilizing member 1098i can generally be located in a central region (for example, generally parallel to the region between the fins 1024i) of the lingual cavity 1068i, although not necessary. In this specific embodiment, the stabilizing member 1098l extends from the gingival side of the lingual opening 1064 to an intermediate position within the lingual cavity 1068i so that each deformable finger 1062l extends along at least one side of the stabilizing member 1098i.
[0064] In use, the deformable fingers compress each other to reduce the overall width of the lingual free end portion 1028i for insertion through the lingual opening. Since the free lingual end portion extends through the lingual opening 1064i, the deformable fingers return to an unstressed position, which includes a width generally less than the width of the engaging ribs of the stabilizing member 1098i. The insertion of the locking clip 1026h continues into the lingual cavity 1068i, where the flange portions 1066i are deflected out in contact with a first pair of engagement ribs 1100i until the flange portions 1066i are received in the pair of grooves in the open position 1094i and will remain as long as the bracket is in the open position. To obtain the closed position, the locking clamp 1026i is inserted again (gingivally) into the lingual cavity 1068i, where the flange portions 1066i are again deflected out in contact with a second pair of engagement ribs 1102i to the flange portions. 1066i be received in the pair of slots in the closed position 1096i so that the bracket 1010i is substantially maintained in the closed position. To return the bracket to the open position, the locking clamp 1026i is moved occlusally to the second pair of engagement rings until the flange portions 1066i are received in the grooves in the open position 1094i. The active engagement of the deformable fingers 1062i (for example, flange portions 1066i) and the stabilizing member 1098i (grooves in the closed position) assist in inhibiting movement (for example, sprain, mesial-distal movement, and / or other) of the clamp locking 1026i while in the closed position.
[0065] The 1010i self-ligating dental bracket can incorporate a 1064i lingual opening (eg through hole), which can include two 1064i 'channels extending from the gingival rib fins 1016i to a single 1064i channel ”in the 1018i occlusal ligation fins to a lingual portion of the body to facilitate cleaning of calculus / retained tartar.
[0066] FIGS. 10C-10D provide a self-ligating bracket 1010j, which may include a modified locking arrangement having a locking clamp 1026j and a lingual cavity 1068j having a mesially locking grooves / ratchets located distally to facilitate and securely lock the free lingual end locking clamp both in the open and closed position. In this specific embodiment, the locking clamp 1026j includes a Y / W-shaped lingual free end 1028j having deformable fingers 1062j. The deformable fingers 1062i may include outwardly extending flange portions 1066j which are configured to actively engage the position slots 1094j (to assist in maintaining the bracket in the open position) or grooves in the closed position 1096j (to assist in maintaining the bracket in the closed position) of the mesial and distal side walls 1072j of the lingual cavity 1068j.
[0067] In use, the deformable fingers compress inwardly with respect to each other to reduce the overall width of the lingual free end portion 1028j for insertion through the lingual opening. Since the lingual free end portion extends beyond a first pair of engagement ribs 1100j, the deformable fingers attempt to return to an unstressed position while the flange portions 1066j are received in the open position pair 1094j and will remain as long as the bracket is in the open position. To obtain the closed position, the locking clamp 1026j is inserted again (gingivally) into the lingual cavity 1068j, where the flange portions 1066j are again diverted inwardly in contact with a second pair of engagement ribs 1102j to the flange portions 1066j be received in the pair of grooves in the closed position 1096j so that the bracket 1010j is substantially maintained in the closed position. To return the bracket to the open position, the locking clip 1026j is moved occlusally to the second pair of engagement ribs 1102j until the flange portions 1066j are received in the open position grooves 1094i. The active engagement (for example, compression flange portions (stressed position) so that an outward force on the side walls 1072j is provided) on the deformable fingers 1062j (e.g., flange portions 1066j) and the stabilizing member 1098j (grooves) in the closed position) assist in inhibiting the movement (for example, sprain, mesial-distal movement, and / or other) of the locking clamp 1026j while in the closed position.

In this specific embodiment, the width of the stabilizing member 1098k and the width of the spacing between the deformable fingers 1062k can be configured to match (for example, adjustment and / or active engagement) with another to assist in inhibiting movement (for example , sprain, mesial-distal movement, and / or other) of the locking clamp 1026k while in the closed position.
[0069] As shown in FIGS 11A-11B, the lingual cavity 1068k can also include a chamfered portion (e.g., recess) 1099k to guide the lingual free end portion 1028k of the locking clamp 1026k and assist in expanding the locking clamp 1026 during the transition from the open to the closed position. In addition, the chamfered portion 1099k can be configured to provide clearance for the curved portion 1032k of the locking clip 1026k while in the closed position.

The rib portion 1104l being spaced spaced from the gingival side wall 1073l and configured to engage the bridge portion 11081 having a corresponding mesial-distal groove 1111l for a positive lock to substantially keep the locking clamp in the closed position. The wedge portion being occlusally positioned within the cavity at a central location and configured to substantially prevent the locking clamp 1026l from being removed from the lingual cavity 1068l. In this specific embodiment, the positive locking of the bridge portion with the rib and / or the wedge adjustment 1106l within the corresponding spacing between the deformable fingers 10621 are configured to assist in inhibiting movement (for example, sprain, mesial- distant, and / or other) of the locking clip 10261 while in the closed position. In addition, the width of the neck portion 1029l can match (for example, fit) the mesial-distal width of the lingual cavity 1068l (and the lingual opening 10641) to also assist in inhibiting movement (for example, sprain, mesial- distant, and / or other) of locking clip 10261 while in the closed position.

Optionally, the mesial-distal width of the free lingual end 1028m (for example, usually taken through the 1066m flange portions) is configured to be wider (in a non-stressed state) than the mesial-distal width of the lingual cavity 1068m. so that when inserting into the lingual cavity 1068m, the flange portions 1066m can exert an outward force (eg, in a stressed state) on the respective mesial and distal side walls 1072m to assist in inhibiting movement (eg, sprain, mesial-distal movement, and / or other) of the locking clamp 1026m while in the closed position.
[0072] FIGS. 14A-14C are various views of another alternative embodiment of the self-ligating bracket shown in FIG. 11A in which the lingual cavity 1068m may also include a plurality of stabilizing members spaced mesially-distally 1098m extending from a gingival lateral wall 1073m generally in a centralized location with the lingual cavity 1068m. In this specific embodiment, the locking clamp 1026m can also include a stabilizing finger 1110m extending from the free lingual end 1028m and the middle of the deformable fingers 1062m. The width of the stabilizing finger 1110m and the width of the space between the stabilizing members 1098m are configured to match (eg, actively engage and / or engage) with each other to assist in inhibiting movement (eg, sprain, mesial- distant, and / or other) of the locking clamp 1026m while in the closed position. Optionally, the mesial-distal width of the free lingual end 1028m (for example, usually taken through the 1066m flange portions) is configured to be wider (in a non-stressed state) than the mesial-distal width of the lingual cavity 1068m so that on insertion into the lingual cavity 1068m, the flange portions 1066m can exert an outward force (for example, in a stressed state) on the respective mesial and distal side walls 1072m to assist in inhibiting movement (for example, sprain, movement mesial-distal, and / or other) of the locking clamp 1026m while in the closed position.
[0073] FIGS. 14A-14C are various views of another alternative embodiment of the self-ligating bracket shown in FIG. 13A in which the lingual cavity 1068n also includes a single stabilizing member 1098n extending from a gingival side wall 1073n generally in a central location. In this specific embodiment, the mesial-distal width of the lingual free end 1028n (for example, usually taken through the 1066n flange portions) can be configured to be wider (in an unstressed state) than the mesial-distal width of the lingual cavity 1068m (for example, from the mesial sidewall to the distal sidewall) so that when inserting into the lingual cavity 1068n the flange portions 1066n can exert an outward force (for example, in a stressed state) on the respective walls 1072n mesial and distal sides to assist in inhibiting movement (eg, sprain, mesial-distal movement, and / or other) of the 1026n locking clip while in the closed position. In addition, the locking mechanism may also include a wider stabilizing member 1098n of the lingual cavity 1068n, a ratio of mesial-distal width of the lingual free end portion 1028n to mesial-distal width of the lingual cavity 1068, or both so that additional force can be provided by an intermediate portion 1112n of the deformable fingers 1062n on the stabilizing member 1098n to also assist in inhibiting movement (eg, sprain, mesial-distal movement, and / or other) of the locking clamp 1026n while in closed position.
[0074] FIGS. 15A-15C are various views of another alternative embodiment of the self-ligating bracket shown in FIG. 3E wherein the lingual free end 1028o of the locking clip 1026o may also include a neck portion 1029o and intermediate grooves 1114o to assist in deformation of the deformable fingers 1062. In this specific embodiment, the mesial-distal width of the free end portion lingual 1028o (for example, usually taken through the 1066o flange portions) can be configured to be wider (in a non-stressed state) than the mesial-distal width of the lingual cavity 1068o (for example, from the mesial sidewall to the wall lateral) so that at insertion into the lingual cavity 1068o the flange portions 1066o can exert an outward force (for example, in a stressed state) on the respective mesial and distal side walls 1072o to assist in inhibiting movement (for example , sprain, mesial-distal movement, and / or other) of the locking clamp 1026o while in the closed position. In addition, the neck portion 1029o can extend into the lingual cavity (while in the closed position) and can be measured corresponding to the width of the lingual opening 1064o to assist in targeting the locking clamp 1026o during the transition between the open and closed positions .
[0075] FIGS. 16A-16C are various views of another alternative embodiment of the self-ligating bracket shown in FIG. 3E in which the wider mesial and distal side walls 1072p can be provided so as to be generally edges of mesial and distal flow 1116p from the lingual opening 1064p (occlusal side of the body) thereby resulting in a reduced lingual cavity 1068p. In addition, the locking clamp 1026p can also include a U-shaped lingual free end 1028p having deformable fingers 1062p with inwardly facing flange portions 1066p forming a gingival opening 1118p between them. The flange portions 1066p may include opposite edges 1120p having angular, curved, and / or other portions, to assist in sustaining the locking clip 1026p to the bracket body 1012p. More particularly, during the installation of the locking clamp 1026p, the lingual free end 1028p is inserted gingivally at the occlusal location of the lingual opening 1064p where the opposite edges 1120p of the flange portions 1066p are brought into contact with an occlusal protuberance 1122p of the lingual cavity 1068p . The deformable fingers 1062p can be deformed outwardly in this way by increasing the width of the gingival opening 1118p to allow the occlusal protuberance 1122p to pass through the gingival opening 1118p. In doing so, the lingual free end 1028p is allowed to be reinserted into the lingual cavity to secure the locking clip to the body 1012p. The gingival opening 1118p can be configured so that the gingival side of the gingival opening 1118p allows the passage of the occlusal protuberance 1122p during the installation of the locking clamp while the occlusal side of the gingival opening which substantially prevents the passage of the occlusal protuberance 1122p so that the locking clamp can remain attached to the 1012p body. Desirably, the neck portion 1029p can be extend into the lingual cavity (while in the closed position) and can be measured corresponding to the width of the lingual opening 1064p to assist in directing the locking clamp 1026p during the transition between the open and closed positions. Desirably, the width of the neck portion 1029p (for example, from the distal edge of the distal deformable finger to the mesial edge of the mesial deformable finger) can match (for example, adjust to) the mesial-distal width of the 1068p lingual cavity (and the lingual opening 1064p) to again assist in directing the locking clamp between the open or closed positions and / or inhibiting the movement (for example, twisting, mesial-distal movement, and / or other) of the locking clamp 1026p while in the closed position .
[0076] In yet another embodiment of the present invention, a self-ligating orthodontic bracket is shown in FIGS. 17A-171, and is generally indicated by reference number 610. As can be seen, the orthodontic bracket 610 includes a body 612, a lingual support base 614 attached to the body, and a locking mechanism having a locking clamp 626 and a retaining member 627. The body 612 may include a pair of laterally spaced gingival fin fins 616 and a pair of laterally spaced occlusal ligation fins 618 extending from the lip surface of the body 612. The gingival fin fins 616 and the 618 occlusal strapping fins generally curve lingually. A slit in the orthodontic wire 620 extends mesial-distally through the body 612 and between the gingival ligation fins and occlusal ligation fins 616 and 618. The slot in the orthodontic wire 620 opens labially to receive an orthodontic wire 622.
[0077] A first bridge portion 660 and a second bridge portion 661 are provided in a region between the fins 624, with the first bridge portion 660 rotating between the gingival rib fins 616 and the second bridge portion 661 rotating between the occlusal strapping fins 618. It is appreciated that the first and second bridge portions 660 and 661 extend from the lip surface of the orthodontic wire slit (and defining the portions thereof) to the lip surfaces of the respective strapping fins 616 and 618 .
[0078] Retaining member 627 may include a first pair of stops 644 and a second pair of stops 646 in the gingival strap fins 616 to inhibit inadvertent movement of the locking clip 626 from a closed position (e.g., a first position closed active at stops 644 or a second closed position at stops 646) to an open position and optionally to keep locking clamp 626 open when it is rotated to the open position. Each stop defining a first opening, at least a guide portion, and at least one flange. The first pair of stops 644 extends generally outside the respective gingival strap fins 616 and includes a first opening 664, a first guide portion 674, and a first flange 668 for engaging with the locking clamp 626 to hold the first closed position (for example, active bracket for the first active closed position). Similarly, the second pair of stops 646 extends generally outside the respective gingival strap fins 616 and includes a second opening 666, a guide portion 675, and a second flange 669 for engaging with the locking clamp 626 to maintain the second closed position (for example, passive bracket for the second closed passive position). It is appreciated that the first and second pairs of stops 644 and 646 can be positioned so that one stop of each pair of stops 644 and 646 is gingival-occlusally juxtaposed to the respective other stop of each pair of stops 644 and 646. Desirably, the pairs of stops in each gingival tie can define a generally W-shaped configuration. It is also appreciated that the pairs of stops can be located in any connection, for example, close to the respective internal surfaces of the 616 gingival rib fins close to the region between the 624 fins.
[0079] Locking clamp 626 is pivotally mounted on occlusal locking fins 618 and is movable between two closed positions (FIGS. 34-37) where access to the orthodontic wire groove 620 is inhibited and an open position (FIG. 31 -33) where access to the 620 orthodontic wire groove is allowed. It is appreciated that the locking clamp 626 is in the form of the spring element having a configuration generally in the form of Y. More particularly, the locking clamp 626 may include a top portion 628, with a pair of arms on opposite sides 650 and 652, which defines an opening 629 between them. It is appreciated that the top portion 628 and / or the side arms 650 and 652 are configured to extend through the slot of the orthodontic wire 620.
[0080] Arms 650 and 652 may include free ends (for example, extending generally mesial and distal, even if not necessary) that are turned inward to define separate hook ends directed opposite 672. Hook ends (gingival) 672 can be received in the respective first openings 664 or the respective second openings 666, which are formed in the gingival strap fins 616.
[0081] Locking clamp 626 may also include connecting the top 628 and a base portion 692 having free opposite ends (for example, extending generally mesial and distal, even if not necessary) that are turned outward to define ends of oppositely directed tail spaced 632 and 634 respectively. Each of the tail ends 632 and 634 is received in a respective perforation 636 and 638 formed in one of the occlusal strapping fins 618. Perforations 636 and 638 can extend (for example, mesial-distally) completely through the respective flaps. tie 618 or partially through them.
[0082] To close orthodontic bracket 610 in the first closed position, locking clamp 626 is pivoted close to tails 632 and 634 for the first pair of stops 644 (for example, first pair of gingival stops) of the locking mechanism 627 next to the gingival rib fins 616. Hook ends 672 (e.g. 672a and 672b) make contact with and are gingivally guided along the respective labial surfaces of the first guide portions 674. Hook ends 672 are continuously guided along from the labial surfaces of the first guide portions 674 to the hook ends 672 that extend beyond the flanges 668 of the first pair of stops 644. This allows the locking clamp 626 to return to its unstressed state so that the hooks 672 engage the respective flanges 668 thus maintaining the locking clamp 626 in the first closed position. In doing so, the locking clamp 626 is lingually deflected so that the contact between the locking clamp, the orthodontic wire, and the gap in the orthodontic wire can be substantially or completely maintained while in the first closed position (FIGS. 36A, 36B, and 37).
[0083] More particularly, the reaction force applied to the labial surface of the first guide portions 674 by the hook ends 672 causes the locking clip 676 to deviate (e.g., gingivally) in a stressed state. When the hook ends 672 are pivoted beyond the respective first stops 644 and generally lingually in the first openings 664, the locking clamp 626 returns to the first flanges 668 in an attempt to return to its unstressed state. In doing so, the first flanges 668 of the first pair of stops 644 prevent removal of the respective hook ends 672 from the first opening 664 during its first closed position. The first flanges 668 inhibit the locking clamp 626 while in this stressed condition of moving again to the open position. In this way, the gap of the orthodontic wire 620 remains closed in this way actively holding the orthodontic wire 622a in the gap of the orthodontic wire.
[0084] To close the orthodontic bracket 610 in the second closed position, the locking clip 626 is pivoted close to the tails 632 and 634 for the second pair of stops 646 of the locking mechanism 627 next to the gingival strap fins 616. The ends of hook 672 make contact with and are gingivally guided along the respective labial surfaces of the second guide portions 675. The hook ends 672 are continuously guided along the labial surfaces of the second guide portions 675 until the hook ends 672 extend to the long (e.g., gingival-lingually) of the first flanges 669 of the second pair of stops 646. This allows the locking clamp 626 to return to its unstressed state so that the hook ends 672 engage the respective second flanges 669 in this way keeping locking clamp 626 in the second closed position. In doing so, the locking clamp 626 can be shifted slightly slightly lingually so that minimal contact, or no contact between the locking clamp 626 and the orthodontic wire, can be maintained while in the second closed position (FIGS. 34A, 34B, and 35).
[0085] More particularly, the reaction force applied to the labial surface of the second guide portions 675 by the hook ends 672 causes the locking clamp 676 to deviate (e.g., gingivally) in a stressed state. When the hook ends 672 are pivoted beyond the respective second stops 646 and, generally, lingually in the second openings 666, the locking clamp 626 returns to the second flanges 669 in an attempt to return to its unstressed state. In doing so, the second flanges 669 prevent removal of the respective hook ends 672 from the second openings 666 during their second closed position. As such, the second flanges 669 inhibit locking clamp 626 while in this stressed condition from returning to the open position. In this way, the slot of the orthodontic wire 620 remains closed, thereby passively holding the orthodontic wire 622b in the slot of the orthodontic wire.
[0086] To release the orthodontic wire, locking clamp 626 is pushed gingival-lingually to disengage the hook ends 672 from the respective first or second pair of stops 644 and 646. In a specific example to release the orthodontic wire from the first position closed, the hook ends 672 are first moved gingival-lingually (typically along the labial surface of a third guide portion 676) in addition to the first flanges 668. In another specific example to release the orthodontic wire from the second closed position, the ends hook pins 672 are first moved gingival-lingually (typically along the lip surface of a first guide portion 674) in addition to the second flanges 669. Then, the locking clamp 626 can be removed from the respective first and second pair of stops 644 and 646 so that locking clamp 626 (in its unstressed state) is free to pivot close to tails 632 and 634.
[0087] In a specific example, it is considered that as locking clamp 626 is moved (for example, directed or pushed gingivally) along the first guide 674, locking clamp 626 disengages from the second pair of stops 646. Once as the locking clamp 626 is moved beyond the first pair of stops 644, the hook ends 672 incline lingually-occlusally at the first opening 664 thereby transitioning the locking clamp from the second closed position to the first closed position.
[0088] Optionally, bracket 610 can also include a groove 680 to receive an optional bandage. When included, groove 680 can be positioned between along the outside of the tie fins 616. It is appreciated that groove 680 can be configured to assist in releasing locking clamp 626 from the second closed position and / or the first closed position providing the access to the arms of the locking clamp 626. For example, while the locking clamp 626 is being moved (for example, directed or gingivally pushed) from the first closed position along the third guide 676, the hook ends 672 will be directed lingually and under the lingual free ends of the locking fins in the groove 680 such that the spring tension of the locking clamp will automatically move (for example, labially straight) the locking clamp 626 through the groove 680 to the open position.
[0089] FIGS. 17J-17L are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 17A-17I wherein the occlusal locking clip portion 626a includes a pair of lingually curved arms 696a for pivotal engagement with holes 636a and 638a. Arms 696a being spaced apart to define a portion of the occlusal locking clip generally in the form of Y 626a.
[0090] Self-ligating brackets having a ratchet design can include a single ratchet or a plurality of ratchets that can be attached to the tie strap (e.g., gingival strap or fins) of the bracket body. Ratchets can be an integral part of the gingival ligature fins (outside and inside), or they can be permanently attached to the ligature fins using an appropriate manufacturing method, or they can be attached to any other (appropriate) location on the body. The ratchet design may have multiple slits to lock the top legs of the clamp (on a labial portion of the orthodontic wire clamp and preferably on a labial free end of the clamp) when closed.
[0091] It is believed that this coupling design can be configured such that the clamp can be opened and / or closed simply by pushing the clamp with one finger and / or another (for example, a tool). Advantageously, this ratchet-based latching mechanism can be configured such that the need for an instrument to open or close the clamp can be eliminated compared to the prior art.
[0092] FIGS. 18A-18D are various views of an alternative embodiment of the self-ligating bracket shown in FIGS 17A in which a modified "ratchet" based mechanism can be provided having a locking clamp 626b and a retaining member 627b. The body 612b may include a pair of laterally spaced gingival fin fins 616b and a pair of laterally spaced occlusal ligature fins 618b extending the body 612b. The gingival strap fins 616b generally bend lingually thereby forming a portion of the retaining member 627b.
[0093] Retaining member 627b may include a pair of opposing stops 644b on the gingival strap fins 616b to inhibit inadvertent movement of the locking clamp 626b from a closed position to an open position and optionally to keep the locking clamp 626b open when it is pivoted to the open position. The stops 644b may be an integral extension of the respective gingival strap fins 616b by bending lingually from these to form the opening 664bs, guide portions 674b, and flanges 668b for engaging with the locking clamp 626b to maintain a closed position. Desirably, the 644b stops on each gingival fin can define a generally hook-like configuration, even if not necessary.
[0094] Locking clamp 626b may include a base portion 692b having the opposite base arms 693b being pivotally mounted on the occlusal fastening fins 618b. The spaced base arms 693b may also include the oppositely directed tail ends 632b and 634b respectively. Each of the tail ends 632b and 634b is received in a respective orifice 636b and 638b formed in one of the occlusal fastening fins 618b. In this specific embodiment, the base arms 693b are generally flat.
[0095] It is appreciated that the locking clip 626b can be in the form of a spring element having a configuration generally in the form of T. More particularly, the locking clip 626b can include a top portion 628b and an intermediate portion 649b which generally covers the gap of the orthodontic wire 620b while in the closed position. The top portion 628b and the intermediate portion 649b can include a pair of side arms 650b and 652b, respectively, which extend mesially and distally from the top portion 628b and intermediate portion 649b to define the recesses 651b between them. The arms 650b can be received in the respective openings 664, which are formed in the gingival strap fins 616 to hold the locking clamp 626b in the closed position.
[0096] Optionally, bracket 610b can also include grooves 680b to receive an optional bandage. When included, the groove 680b can be positioned along the outside of the gingival rib fins 616b. It is appreciated that the groove 680b can be configured to assist in releasing the locking clamp 626b (e.g., arms 650b) from the closed position by providing access to the arms 650b of the locking clamp 626b. For example, while the locking clamp 626b is being moved (for example, directed or pushed gingivally) from the closed position along the guide 674b, the arms 650b will be directed lingually and under the lingual free ends of the strapping fins in the groove 680b such that the spring tension of the locking clamp will automatically move (for example, labially direct) the locking clamp 626b through the groove 680 to the open position.
[0097] FIGS. 19A-19E are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 18A-18D where the retaining members 627c have been reduced to extend into a portion of the gingival strap fins 616c. In doing so, the hook portions of the 616c gingival fin fins may be available to receive the optional bandage (s).
[0098] The interactivity between the locking clamp 626c and the orthodontic wire 622c in the final active stage can be critical from a clinical perspective. It is believed that the variation in the design of the clamp may allow interactivity between the clamp and the orthodontic wire. Generally, interactivity can be defined as a clamp having some space to move (for example, "float" and / or mobile while in the closed position). For example, as shown in FIG. 19D, an enlarged view of a "ratchet" member is provided, which alone or in combination with an opposite ratchet member can be configured to achieve this type of interactivity. More particularly, as shown if FIG. 19D, a clearance can be obtained while the labial free end of the clamp engages the locking ratchet slot after the clamp is in the closed position.
[0099] The middle of the clamp (for example, the section of the clamp that can generally be in contact with orthodontic wire) can be flexible enough to generally maintain a predetermined interactivity. Both the change in geometry (ie less material) and / or softer material of the clamp can be improved to improve the predetermined interactivity between the middle section of the clamp and the orthodontic wire (FIG 19C).
[00100] Once the clamp is in the locked position, the tension force (spring) can be generated in the clamp. As a result, it is appreciated that when the clamp is pushed down (for example, lingually) beyond the final locked position, the tension will pull the end of the clamp (for example, postformed in the T-shape or different at the free labial end) of the clamp) so that the clamp can be released from the slit (for example, gingival ratchet slit (s)) to the open position.
[00101] FIGS. 20A-20B are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 19A-19E wherein the base portion 692d of the locking clip 626d can include curved base arms 693d.
[00102] FIGS. 21A-21C are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 19A-19E wherein the tail ends 632e and 634e can generally be provided as rectangular members extending from the base arms 693e. In doing so, the respective holes 636e and 638e were rectangular openings modified to correspond with the rectangular tail ends 632e and 634e.
[00103] FIGS. 22A-22C are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 19A-19E in which the holes 636f and 638f have been configured as a shape of figure 8 so that the locking clamp 626f can slide-rotate between an open position (for example, a lingual-occlusal side 636f 'and 638' of the respective holes 636f, 638f) and a closed position (for example, a lip-gingival side 636f ”and 638r of the respective holes 636f, 638f).
[00104] FIGS. 23A-23B are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 19A-19E in which the holes 636g and 638g have been configured as a shape of figure 8 so that the locking clamp 626g can slide-rotate between an open position (for example, a lip-occlusal side 636g 'and 638g' of the respective holes 636g, 638g) and a closed position (for example, a lingual-gingival side 636g ”and 638g” of the respective holes 636g, 638g).
[00105] Unlike the free rotating articulated clamp design that only rotates around the fulcrum as disclosed herein, this additional embodiment may include both the rotational and sliding movement separately or preferably at the same time. It is believed that with the sliding movement during the closing of the clamp, FIGS. 23D-23E, less stress can be generated on the clamp so that permanent deformation can be prevented.
[00106] FIGS. 24A-24B are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 19A-19E in which a second pair of 666h (lingual) retaining openings can also be provided. In this specific embodiment, the retaining member 627h can include a first pair of stops 644h and a second pair of stops 646h in the gingival strap fins 616h to inhibit the inadvertent movement of the locking clamp 626h from a closed position (for example, for example, a first active closed position at stops 644h or a second closed position at stops 646h) for an open position and optionally to keep locking clamp 626h open when it is pivoted to the open position. Each stop defining a first opening, at least a guide portion, and at least one flange. The first pair of 644h stops generally extends out of the respective gingival rib fins 616 and includes a first opening 664h, a first guide portion 674h, and a first flange 668h for engaging with the locking clamp 626h to hold the first closed position (for example, active bracket for the first active closed position). Similarly, the second pair of stops 646h generally extends outside the respective gingival strap fins 616 and includes a second opening 666h, a guide portion 675h, and a second flange 669 for engaging with the locking clamp 626h to maintain the second closed position (for example, passive bracket for the second closed passive position). It is appreciated that the first and second pairs of stops 644h and 646h can be positioned so that one stop of each pair of stops 644h and 646h is gingival-occlusally juxtaposed to the respective other stop of each pair of stops 644h and 646h. Desirably, the pairs of stops in each gingival tie can define a configuration generally in the W shape.
[00107] As shown in FIGS. 22 and 24, the present invention may include another for making a self-ligating bracket having a clamp sliding / pivoting mechanism that can be configured to reduce tension on the clamp and / or prevent any permanent deformation resulting from the clamp so as to generally maintain staple functionality.
[00108] The present invention can also provide another embodiment of the self-ligating bracket as shown in FIGS. 25A-25H. Generally, the self-ligating bracket may include a molded body with a base and a C-shaped clamp. The clamp has two folded ends that slide over the orthodontic wire slit in both gingival and occlusal directions and depending on the closure method (gingival or occlusal) ), the system will behave as an asset or a liability during the course of the treatment. More particularly, the bracket concept has three components (see photo above): Body, Clamp and Base. The clamp can be formed as a C and it is able to close in both gingival and occlusal mode. As a rectangular / square orthodontic wire sits in the body slit, this clamp can express both passive and active engagement with the same orthodontic wire depending on which end the clamp covers the crevice in the orthodontic wire. The uniqueness of this concept is the ability to change from a passive stage to an active stage (or vice versa) without changing the thread. However, it is anticipated that the circular wire will tend to remain in the passive stage in both gingival and occlusal closure. The clamp has a C-shape (see the following photo) and has two folded ends. The two folded ends of the clamp have two different clamp transpositions (see the red arrows in the following photo). In the orthodontic treatment stages, the bracket has the passive stage (no contact between the orthodontic wire and the clamp) and the active stage (Interference contact between the orthodontic wire and the clamp). See the following pictures for details. In the Passive stage (FIG. 25G) when the larger end (for example, gingival termination) of the clamp covers the orthodontic wire, there is no contact between the clamp and the orthodontic wire. When the clamp is in the open position, it does not cover the orthodontic wire, FIG. 25H. In the Active stage (FIG. 251) when the final end of the clamp covers the orthodontic wire, there is an interference contact between the clamp and the orthodontic wire. Desirably, dual-stage brackets can be designed to have interactivity between the clamp and the orthodontic wire for both the passive and active stages.
[00109] FIG. 25J shows the interactivity between the orthodontic wire and the occlusion end of the clamp in the passive stage. The same main design can be used for the gingival termination of the clamp in the Active stage for interactivity between the orthodontic wire and the gingival termination of the clamp. Desirably, during the Passive stage, there is no physical contact between the orthodontic wire and the clamp. However, in some tight occlusal cases, the orthodontic wire will begin to come into contact with the clamp. Due to the unblocking of the clamp in the retention channel (area between the free occlusal end of the clamp and the lingual surface of the retaining wall (for example, hook), the interactivity between the clamp and the orthodontic wire will be obtained.
[00110] In this specific embodiment, the self-ligating bracket of the present invention wherein the bracket 1010q includes a modified locking clamp 1026q and a modified receiving member 1036q. The receiving member 1036q may include a first receiving member 1036q ', which may be mesially or distally located near the gingival loops 1016q of the bracket body 1012q and may include a non-continuous (e.g., latent) retention channel 1090q which includes mesial and distal portions 1091q to allow a positive seat for the respective flap portions 1031q of the locking clamp 1026q. Desirably, the mesial and distal portions 1027q of the retention channel 1090q generally extend parallel to the slit of the orthodontic wire 1020q. In this specific embodiment, the width of the locking clip 1026q at the labial free end 1030q can generally be the same mesial-distal width as the bracket body 1012q. In addition, the labial free end 1030q of the locking clip 1026q may include a notch portion 1034q disposed between the flap portions 1031q. The retention channel can also be defined by a profile generally in a C-shape to not only provide a positive seat (and limit lingual movement of the free lip end 1030q), but can also provide a hook portion 1038h to limit the lip movement of the lip free end 1030h while in the closed position. Optionally, the height (for example, labial-lingual height) of the 1090q retention channel can be sufficiently measured (for example, less than or equal to the thickness of the orthodontic wire) so that the trapping of the orthodontic wire can be substantially prevented while the portion free end 1030q of locking clip 1026q is in the closed position.
[00111] The receiving member 1036q can also include a second receiving member 1036q ”, which can be centrally located close to the region between the 1024q fins between the 1018q occlusal strapping fins. The region between the 1024q fins may include an open stop groove 1042 having protrusions 1044q to assist in the movement of the clamp from an open position to a closed position. Desirably the width of the 1122q lip-occlusal free end corresponds to the width of the region between the 1024q fins to receive the 1122q lip-occlusal free end.
[00112] In this embodiment the bracket 1010q can be configured for two closed positions (an active closed position and a passive closed position) and an open position. In the active closed position (FIG. 25G), the locking clamp 1026q is occlusally displaced such that the labial-gingival free end 1030q is actively engaged with the locking clamp 1026 of the orthodontic wire 1022q. In the passive closed position (FIG 25H), the locking clamp 1026q is gingivally displaced such that the free labial-occlusal end 1122q closes (e.g., covers) the groove of the orthodontic wire 1020 while substantially free from contact with the orthodontic wire. Advantageously, the locking clip 1026q can also be gingivally displaced as shown in FIG. 25I to accommodate the smaller orthodontic wires in a passive closed position. In the open position (FIG. 25F), the locking clamp 1026q is generally positioned so that a spacing 1124q between the free labial-gingival end 1030q and the free labial-occlusal end 1122q is generally oriented parallel to the groove of the orthodontic wire 1020 in order to allow the removal of the 1022 orthodontic wire, located therein.
[00113] FIGS. 26A-26H are various views of another embodiment of a self-ligating bracket of the present invention, which may include a body 1012r (eg, rhomboid body design) molded with a base 1014r and at least one clip 1026r (eg, a plurality of staples). More particularly, the clamps 1026r (e.g., metal clamps) and gear racks of the body 1126r can be formed through a micromachining process process. The 1026r clamp and the 1012r body can be designed as a combination or different gear rack mechanism along the labial-lingual direction allowing the clamp to lock in different positions for different wire sizes. The adjustable clamps 1026r include racks 1128r, which match and / or associate with the respective gear racks of the body 1126r for ratcheting / adjusting the clamps 1026r. Adjustable 1026r clamps can also allow adjustment between a passive, active, and interactive hitch on the orthodontic wire (for example, Passive hitch refers to when the clamp does not come into contact with the orthodontic wire while the Active hitch can refer to when the clamp is applying force directly to the orthodontic wire). Interactive engagement can occur when the clamp engages with the orthodontic wire, but does not apply a force or substantially no force to the orthodontic wire. When a plurality of clamps are included, the two clamps are desirably independent of each other so that it is possible to have an engagement with the orthodontic wire on one side alone.
[00114] Staple-wire interactions can be adjusted in several ways. For example, the clamp-wire interaction can be adjusted by one or more of the following, but are not limited to: Active engagement on the orthodontic wire on the mesial and distal sides of the bracket body; Passive coupling on the orthodontic wire on the mesial and distal sides of the bracket body; Interactive coupling on the orthodontic wire on the mesial and distal sides of the bracket body; Active Coupling on the orthodontic wire on the mesial side and Passive Coupling on the distal side of the bracket body; Active Coupling on the orthodontic wire on the distal side and Passive Coupling on the mesial side of the bracket body; Interactive coupling on the orthodontic wire on the mesial side and Passive coupling on the distal side of the bracket body; The interactive coupling on the orthodontic wire on the distal side and the Passive Coupling on the mesial side of the bracket body; Active Coupling on the orthodontic wire on the mesial side and Interactive Coupling on the distal side of the bracket body; Active Coupling on the orthodontic wire on the distal side and Interactive Coupling on the mesial side of the bracket body; and any combination of these.
[00115] The 1026r clamps can be opened using a chisel or other common dental instrument by applying force to the edge of the 1128r gear rack (eg ratchet system) on the clamp and pushing the clamp in the labial direction. The orientation of the 1128r gear rack allows the clamps to be closed by pushing them in the lingual direction. As shown in FIGS. 26G-26H, a round 1130r handle on the clamp on the opposite side of the gear rack allows the clamp to slide easily in the lip direction to an 1132r stop that is formed on the bracket body. When the 1130r round handle reaches the 1132r stop on the body, the 1128r gear rack on the clamp is disengaged from the 1126r association gear rack on the body and the clamp can then pivot so that it no longer blocks the 1020r orthodontic wire slot and one orthodontic wire 1022r can be removed or inserted (FIG. 261). One 1134r post (for example, hook) can be attached to each clamp for connecting elastic bands. The elastics that can be bonded can be used for aesthetic purposes allowing different bandages in colors to be bonded with effect on the bracket performance. Elastic bands can also be attached to help with leveling, alignment and tooth displacement.
[00116] FIGS. 27A-27G are various views of another alternative embodiment of the self-ligating bracket shown in FIGS. 24A-24B in which a first and second pair of retaining members are provided on the occlusal side of the gingival ligation fins. Generally, the self-ligating bracket may include a molded body 612i with a base 6141 and a sliding locking clamp 626i. More particularly, the bracket body may include two retaining channels (e.g., openings) 664i, 666i that can be used to allow the 626i clamp to use two treatment stages (Passive and Active) with the same orthodontic wire. This bracket concept can also be designed to have three different directions, gingival, occlusal, lingual, to open, close and change the treatment stage (Active vs. Passive), respectively.
[00117] The bracket can include three components such as a body, base and clamp. For illustration purposes, a rectangular / square orthodontic wire rests on the body slit. Please note that the slot is also able to accommodate round wires. As shown in the figures, the free labial end 692i of the clamp can be designed to have a “column” (for example, a T-shaped end) as a feature that when closed rests on a passive clamp retention channel (for example, longitudinally spaced lip openings). In this position (FIG. 27F) there may be substantially or completely no contact between the clamp and the orthodontic wire, which is the passive stage of orthodontic treatment.
[00118] Typically, as the treatment progresses, the clamp may need to be changed from the passive stage (no contact between the clamp and the orthodontic wire, FIG. 27F) to the active stage (interference contact between the clamp and the orthodontic wire, FIG. 27G) where the column feature rests on the retention channel of the active clamp (for example, longitudinally spaced lingual openings being generally positioned below the passive retention channels). The mechanism for changing the clamp (FIG 271) from the passive stage to the active stage can be simply applying force and pushing down on the labial free portion of the clamp (shown in the arrows in FIG. 27D), to the active clamp latent channel . As shown in FIG. 27F, the labial free end portion of the clamp can be positioned in a latent mesial-distal groove 1042 while in the open position. The number of clamp retention channels can be reduced or increased if necessary, and the positions of the channel (with respect to the bottom of the orthodontic wire slot) can be changed if necessary as well.
[00119] In this specific embodiment, the retaining member 627 may include a first pair of stops 644i and a second pair of stops 646i on the occlusal side of the gingival strap fins 616i to inhibit the inadvertent movement of the locking clamp 626i of a closed position (for example, a first active closed position on stops 644 or a second closed position on stops 646i) for an open position and optionally to keep locking clamp 626i open when it is pivoted to the open position. Each stop defining a first opening, at least a guide portion, and at least one flange. The first pair of 644i stops generally extends out of the respective 616i gingival fin fins and includes a first opening 664i, a first guide portion 674i, and a first flange 668i for engaging with the 626i locking clamp to hold the first closed position (for example, active bracket for the first active closed position). Similarly, the second pair of stops 646i generally extends out of the respective gingival strap fins 616 and includes a second opening 666, a guide portion 675i, and a second flange 669i for engaging with the locking clamp 626i to maintain the second closed position (for example, passive bracket for the second closed passive position). It is appreciated that the first and second pairs of stops 644i and 646i can be positioned so that one stop of each pair of stops 644i and 646i is gingival-occlusally juxtaposed to the respective other stop of each pair of stops 644i and 646i. Desirably, the pairs of stops in each gingival tie can define a configuration generally in the W shape.
[00120] The locking clamp 626i slides on the occlusal locking fins 618i and is movable between two closed positions (FIGS. 27D-27E) where access to the 620i orthodontic wire groove slot is inhibited and an open position (FIG. 27F) where access to the 620i orthodontic wire slot is allowed. it is appreciated that the locking clamp 626i is in the form of a spring element having a top configuration generally in U-shape. More particularly, the locking clamp 626 can include a top portion 628i, with a pair of opposite side arms 650i and 652i, which defines a T-shaped opening configuration. It is appreciated that the top portion 628i and / or the side arms 650i and 652i are configured to extend through the slot of the orthodontic wire 620i.
[00121] The 650i and 652i arms may include free ends that generally extend mesially and distally outward, even if not necessary. The arms 650i and 652i can be received in the respective first openings 664i or in the respective second openings 666i, which are formed on the occlusal side of the gingival fins 616i.
[00122] To close the orthodontic bracket 610i in the first closed position (active closed position), the locking clamp 626 is slid gingivally to the first pair of 644i stops (for example, first lingual pair of stops) of the nearby 627i locking mechanism 616i gingival fins. Arms 6501 and 652i make contact with and are gingivally guided along the respective labial surfaces of the first guide portions 674i. The arms 650i and 652i are continuously guided along the labial surfaces of the first guide portions 674i until the hook ends 672i extend beyond the flanges 6681 of the first pair of stops 644l. This allows the locking clamp 6261 to return to its non-stressed state so that the arms 650i and 652i engage the respective flanges 668i thereby keeping the locking clamp 626i in the first closed position. In doing so, the locking clamp 626i is lingually deflected so that the contact between the locking clamp, the orthodontic wire, and the gap in the orthodontic wire can be substantially or completely maintained while in the first closed position (FIGS. 27E).
[00123] To close the orthodontic bracket 6101 in the second closed position, the locking clamp 626 is slid to the second pair of stops 646i of the locking mechanism 627i near the occlusal side of the gingival fins 616i. The 650i and 652i arms make contact with and are gingivally guided along the respective labial surfaces of the second guide portion 675i. The arms 650i and 652i are continuously guided along the labial surfaces of the second guide portions 675i until the hook ends 672i extend beyond (e.g., gingivally) the first flanges 669i of the second pair of stops 646i. This allows locking clamp 6261 to return to its unstressed state so that hook ends 672i engage respective second flanges 669i thereby keeping locking clamp 626i in the second closed position. In doing so, the locking clamp 626i can be lingually slightly offset so that minimal or no contact between the locking clamp 626i and the orthodontic wire can be maintained while in the second closed position (FIGS. 27D).
[00124] As disclosed above with reference to FIGS. 27A-27G, different slot locations can provide different clamp states. For example, a slit and / or labially positioned opening can provide a passive closed position (for example, FIG. 27D - usually no contact between the orthodontic wire and the clamp) or a lingually positioned slot can provide a closed stage position. active (for example, FIG. 27E - contact and interference between the orthodontic wire and the clamp). It is appreciated that the ratchets (s) and / or slot (s) can be positioned such that an expressive closed position can result where minimal contact occurs between the orthodontic wire and the clamp.
[00125] Referring now to FIGS. 28A-28B, a self-ligating orthodontic bracket is shown and is generally indicated by reference number 10. As can be seen, the orthodontic bracket 10 includes a body 12 and a lingual support base 14 attached to the body. The mounting base 14 has a lingual surface to be connected to a tooth. The body 12 may include a side wall 15 that extends between the base 14 and a lip surface 19 to define a generally curved perimeter. Desirably, the perimeter of the body 12 defines a circular, oval, or otherwise formed member. However, it is appreciated that the body 12 can be defined through a number of other shaped configurations such as a square-shaped, rectangular, rhomboid, or otherwise formed member. When provided, it is believed that the curved body (e.g., oval) 12 can reduce the dental stone or different formations around the perimeter of the body 12 and / or allow for easy removal.
[00126] A pair of laterally spaced gingival fin fins 16 and a pair of laterally spaced occlusal ligation fins 18 extend from the lip surface 19 of the body 12. The gingival securing fins 16 and occlusal securing fins 18 generally curve lingually. A region between the fins 24 extends gingival-occlusally through the body 12 and can generally be defined by the lateral spacing of the gingival strap fins 16 and the lateral spacing of the occlusal strap fin 18. The region between the fins 24 can be a passage open (for example, unobstructed) or it can be a closed passage (partially or completely obstructed), or different. A gap in the orthodontic wire 20 extends mesial-distally through the body 12 and between the gingival and occlusal ligament fins 16 and 18. The gap in the orthodontic wire 20 opens labially to receive an orthodontic wire 22. The gap in the orthodontic wire 20 is interrupted in the region between the fins 24 of the body.
[00127] It is appreciated that the body 12 can also include an interior slot to receive an optional auxiliary wire. Desirably, the body 12 can include at least one vertical interior slot 25 that extends occlusally-gingivally (for example, generally parallel to the region between the fins 24) through the body 12, even if not necessary.
[00128] The bracket 10 may also include a locking mechanism that includes a locking clamp 26 and a retaining member 27 to hold the locking clamp 26 in the closed position. In one embodiment, the retaining member 27 can include the stops 44 and 46 on the gingival strap fins 16 to inhibit the inadvertent movement of the locking clamp 26 from a closed position to an open position and to maintain the locking clamp 26 open when it is pivoted to the open position. The stops 44 and 46 generally extend to another one of the respective gingival strap fins 16 in order to define a reduced opening 48 in the intermediate fin area 24. Desirably, the stops 44 and 46 can form a circular shape (for example, semicircular) ) that extends from the respective mesial and distal surfaces of the gingival ligament fins 16 on the intermediate fin are 24. However, it is appreciated that the stops 44 and 46 can form others that include curved, arched, angled, flat, or different portions.
[00129] The locking clamp 26 is pivotally mounted on the occlusal locking fins 18 and is movable between a closed position where the access to the orthodontic wire slot 20 is inhibited by the stops 44 and 46 and an open position where access to the slot of the orthodontic wire 20 orthodontic wire 20 is allowed. It is appreciated that the locking clamp 26 is in the form of a spring element having a generally cruciform outline. In one embodiment, the locking clamp 26 may include a gingival top 28, which curves lingually to define a hook projecting forward 72 (e.g., gingivally). The top 28 can include the interconnected opposite side portions 30, which define a width (e.g., mesially-distally) that is typically greater than the width of the reduced opening 48.
[00130] Locking clamp 26 may also include a pair of opposing arms 50 and 52 (for example, arm portions that extend mesially and distally) that generally extend along and through the gap in the orthodontic wire 20. It is it is appreciated that the arms 50 and 52 can at least partially or substantially extend in a parallel manner with the crack of the orthodontic wire 20. Each arm 50 and 52 can form a generally U-shaped configuration having a gingival portion that extends to a occlusal portion with a termination portion 58 between them to define an opening 60 between them. It is appreciated that the end portion 58 can extend as widely as necessary in both the mesial and distal directions to obtain optimal rotational control of the orthodontic wire.
[00131] When included, the gingival and occlusal portions of the arms 50 and 52 can be configured to desirably achieve the direct translation of the forces of the locking clamp 26 to the orthodontic wire 22 along a Face Axis FA (for example, usually perpendicular to the gap in the orthodontic wire 20). As can be seen in FIG. 28D, both the gingival and occlusal portion (for example, corners 86 and 87) of the orthodontic wire 22 can be engaged by the arms 50 and 52 (for example, the gingival and occlusal portions of the arms 50 and 52) in the closed position in order to take the forces of the orthodontic wire 22 directly to the point of AF in the tooth in order to optimize the treatment time of the patient.
[00132] Locking clamp 26 may also include free opposing ends (for example, which generally extend mesial and distal, even if not necessary) which are turned outwardly to define the oppositely directed separate tail ends 32 and 34 respectively. Each tail end 32 and 34 is received in one of the respective holes 36 and 38 formed in one of the occlusal anchoring fins 18. The holes 36 and 38 can extend (for example, mesial-distally) completely through the respective anchoring fins. 18 or partially through them. The tail ends 32 and 34 can include a flange portion 40 and 42 that extends (for example, radially) of the clamp 26. The flange portions 40 and 42 can be configured to act as a stop for the tail ends 32 and 34 when inserted into the respective holes 36 and 38. Desirably, the flange portions 40 and 42 can prevent the tail ends 32 and 34 from extending beyond a predetermined depth in and / or beyond the holes 36 and 38.
[00133] It is also considered that the locking clamp 26 can be in the compressed state such that the tail ends 32 and 34 generally exert a continuous force out of the respective strapping fins 16 (mesially to the mesially gingival strap fin 16 and distally to the distally gingival fin 16) thus keeping the tail ends 32 and 34 within the respective holes 36 and 38. In doing so, tails 32 and 34 are generally free of rotation within the respective holes 36 and 38 to allow the pivotal movement of the locking clamp 26 between the positions.
[00134] In another embodiment, the stops 44 and 46 can form multiple stop portions (e.g., semicircular portions) (not shown), each set of the stop portions extending from the respective inert surface of the gingival fin fins 16 (for example, in the region between the fins 24). For example, multiple stop portions may include a pair of labial-lingually spaced stops along the inner surface of each of the gingival strap fins 16. When included, pairs of opposite pairs of stops can be configured to allow for stapling locking mechanism 26 between an open position and two different closed positions. More particularly, a first pair of opposing lip stops can include a lip-mesial stop and a lip-distal stop while the second pair of opposing lingual stops can include a lingual-mesial stop and a lingual-distal stop, with the first pair of opposite lip stops being labially spaced from the second pair of opposite tongue stops. In the first closed position, the hook 72 can be positioned below the second pair of opposing lingual stops and the lip surface 19 of the body 12 in the area of intermediate gingival fins 24 to define a first active closed position. In the second closed position, the hook 72 can be positioned below between the first pair of opposing lip stops and the second pair of opposing lingual stops in the gingival intermediate fin area to define a second closed position.
[00135] Locking clamp 26 is generally configured to withstand the typical forces incurred by the bracket while substantially holding locking clamp 26 in the closed position. Typical forces may include, but are not limited to, the forces resulting from the movement of the orthodontic wire, the clamp, and / or the bracket with respect to each other or different such as the movement caused by tooth brushing and / or feeding. However, it is appreciated that the clamp 26 can also be configured to allow deformation of it resulting from a sufficient amount of force, which is generally greater than the typical forces described above. For example, as the dentist pushes the top 28 against the stops 44 and 46 with a sufficient amount of force, the opposite side portions 30 deform one another in order to reduce the width of the top 28 thereby allowing the top 28 to pass through of the reduced opening 48 while moving the locking clamp between the open position and the closed position. After passing through the reduced aperture 48, the top 28 generally returns to its typical undeformed shape (e.g., unstressed state).
[00136] The stops 44 and 46 communicate a lip surface of the locking clamp 26 near the hook portion 72 when the locking clamp 26 is in a closed position to inhibit the locking clamp from accidentally opening during application in the patient's mouth
[00137] As can be seen in FIG. 28A, the stops 44 and 46 retain the locking clamp 26 against the orthodontic wire 22 and inhibit the relative movement between the orthodontic wire 22 and the body 12 of the orthodontic bracket 10. To release the orthodontic wire 22, the locking clamp 26 is pivoted close to tails 32 and 34 while applying a sufficient amount of force against the stops 44 and 46. As a sufficient amount of force is being applied to the top 28 during the engagement of the stops 44 and 46, the width of the top 28 is reduced, thus allowing these to pass through the reduced opening 48.
[00138] In another embodiment as shown in FIGS. 28C28D, a self-ligating orthodontic bracket 110 is provided. The bracket 110 may comprise a locking mechanism that includes the locking clamp 126 and an alternative retaining member 127. In this embodiment, the retaining member 127 is in the form of a first member 121 and a second member 123 with an opening reduced 148 among them. The first and second members 121, 123 can extend labially from the labial surface 119 of the body 112 in an occlusal-gingival relationship to another close to the intermediate gingival fin area 124.
[00139] At least one stop similar to that of the previous embodiment can be provided on one of the first or second members 121, 123 to inhibit the inadvertent movement of the locking clamp 126 from a closed position to an open position and to maintain the clamp locking 126 open when locking clamp 126 is pivoted to the open condition. The stop may be included in various shapes and / or configurations such that they provide a reduced opening 148 between the first and second members 121, 123. In a specific example, the second member 123 (for example, occlusally positioned with respect to the first member 121) can include a stop 144 that extends from a gingival surface of the second member 123 in a free termination 128. The stop 144 can generally be similar in shape to the stop 44 as disclosed above including the curved portions to help guide the top 128 clamp 126 between open and closed positions. The first member 121 (gingivally positioned with respect to the second member 123) can include a stop 146 that extends from the occlusal surface of the first member 121 at a free end 130. The stop 146 can generally be formed as an inclined portion that gradually increases the thickness (e.g., tapering) while extending to a flat portion at the free end 130 to help guide the hook portion 172 of the top 28 of the clamp 126 between the open and closed positions. The stops 144 and 146 generally oppose each other to form the reduced opening 148 between them. Desirably, in a non-stressed state, the reduced opening 148 can be dimensioned (occlusally-gingivally) with a maximum spacing that is less than the thickness of the top 128 to substantially prevent movement of the clamp 126 between the open position and the position closed. It is appreciated that the non-stressed state can be defined here as (in the non-stressed state such as in the closed or open positions of bracket 110 shown in FIGS. 6 and 7).
[00140] It is appreciated that at least one or both of the first and second members 121, 123 can be configured to deform away from the other to allow movement of the clamp 126 between open and closed positions. Deformation of the first member 121 and / or the second member 123 can occur on contact by clamp 126 (for example, top 128) with sufficient force (for example, by the dentist). For example, while the dentist pushes the top 128 against the stops 144 and 146 with a sufficient amount of force, at least one (for example, or both) of the first and second members 121, 123 deforms to the other in order to increasing the spacing of the reduced opening 148 between the stops 144, 146 thereby allowing the hook portion 172 of the top 128 to pass through the enlarged reduced opening 148 while moving the locking clamp 126 between the open position and the closed position. After passing through the reduced opening 148, the first member 121 and the second member 123 generally return to their typical undeformed shape (e.g., unstressed state) while returning to their reduced opening 148 at their maximum spacing, thereby maintaining the clamp 28 in open or closed positions. It is also appreciated that the hook portion 172 (or other top portions 128) can deflect deform, and / or compress to pass through the reduced opening 148, even if not necessary.
[00141] More particularly, to close the orthodontic bracket 110, the locking clamp 126 is pivoted close to the tails 132 and 134. While the locking clamp is pivoted, the top 128 of the clamp 126 is pushed into the gingival portion of the region between the fins 124 against the stops 144, 146. The reaction force applied to the stops 144, 146 by the top 128 of the locking clamp 126 causes the at least one of the first and second members 121, 123 to move occlusally-gingivally in a direction contrary to each other. When locking clamp 126 is pivoted beyond stops 144 and 146, the first member 121 and / or the second member 123 returns to its unstressed state (for example, generally vertical and / or perpendicular to the lip surface 119) and the top 126 is angled towards the lip surface 119 to its closed position below the stops 144 and 146. The stops 144 and 146 in this condition inhibit the locking clamp 126 from moving again to the open position. In this way, the gap of the orthodontic wire 120 remains closed holding the orthodontic wire 122 in the gap of the orthodontic wire.
[00142] Referring now to FIG. 28E, yet another embodiment of a self-ligating orthodontic bracket 210 is shown. Bracket 210 may comprise a body 212, a base 214, and a locking mechanism including locking clip 226 and a retaining member 227. Body 212 may include gingival strap fins 216 and occlusal strap fins 218 with a slit in the orthodontic wire 220 extending mesially-distally between them. In this specific example, the body 212 has a rectangular body and includes a first bridge portion 260 in the region between the fins 224, which rotates between the gingival rib fins 216. The first bridge portion 260 extends from the labial surface of the slit of the orthodontic wire 220 for the labial surface of the gingival ligament fins. The body 212 may also include a second bridge portion 261 in the region between the fins 224, which rotates between the occlusal strapping fins 218. It is appreciated that the second bridge portion 261 partially extends from the lip surface of the gap of the orthodontic wire 220 to allow rotation of locking clamp 226. Body 212 may also include an inner slot for receiving an optional auxiliary wire, even if not required. In a specific embodiment, the body 212 may include an interior vertical slot 225 that extends occlusally-gingivally (e.g., generally transverse to the gap in the orthodontic wire 220) through the body 212.
[00143] The locking clamp 226 may be in the form of a spring element generally U-shaped having free distal mesial and distal ends defining the laterally spaced tails 232 and 234. Each of the tails is pivotally received within a of the respective holes 236 and 238 formed without one of the respective occlusal strapping fins 218.
[00144] Retaining member 227 is provided on the first bridge portion 260 and can include opposing stop assemblies 244 and 246 similar to those of the first embodiment, which can be provided on bridge 260 to hold locking clamp 226 inside of recesses 262 in the closed position.
[00145] More particularly, to close the orthodontic bracket 210, the locking clamp 226 is pivoted close to the tails 232 and 234. While the locking clamp 226 is pivoted, the clamp arms 250 and 252 of the top portion 228 are pushed in the bridge portion 260 against the respective opposing stop pairs 244 and 246. The reaction force applied to the opposing stop sets 244 and 246 by the clamp arms 250 and 252 causes the clamp arms 250 and 252 and / or the opposing stops 244 and 246 are deformed thereby allowing the arms of the clamp 250 and 252 to pass through the reduced openings 248 between the open and closed positions. When the clamp head 228 is pivoted in addition to the opposing stops sets 244 and 246, the clamp arms 250 and 252, the opposing stops 244 and 246, or a combination of both will quickly return to their unstressed state and the head 226 is tilted towards the lip surface 219 close to the recesses 262 to its closed position below the respective sets of opposite stops 244 and 246. The sets of opposite stops 244 and 246 in this condition (for example, unstressed state) inhibit lock 226 to move back to the open position. In this way, the groove of the orthodontic wire 220 remains closed thereby holding the orthodontic wire (not shown) in the groove of the orthodontic wire 220.
[00146] Referring now to FIGS. 28F-28G, another embodiment of a self-ligating orthodontic bracket is shown and is generally indicated by reference number 310. In this embodiment, bracket 310 may comprise an oval body 312, a base 314, and a locking mechanism. locking including a locking clip 326 and a retaining member 327. The body 312 may include gingival strap fins 316 and occlusal strap fins 318 with a groove of the orthodontic wire extending mesially-distally 320 between them. A first bridge portion 360 and a second bridge portion 361 can be in the region between the fins 324, with the first bridge portion 360 spanning between the gingival bandage fins 316 and the second bridge portion 361 spanning between the binding ribs occlusal 318. It is assessed that the first bridge portion 360 and / or the second bridge portion 361 may extend partially or totally from the lip surface of the orthodontic wire groove to the lip surface of the respective tie fins 316 and 318. In one specific example, the first and second bridge portions 360 and 362 extend from the lip surface of the orthodontic wire groove to the lip surfaces of the respective anchoring fins 316 and 318.
[00147] The body 312 can also include an internal slot to receive an optional auxiliary wire, although not required. For example, the body 312 may include an internal vertical slot 325 that extends occlusally-gingivally (for example, generally transverse to the groove of the orthodontic wire 320) through the body 312.
[00148] Locking clamp 326 may be in the form of a spring element generally in the form of M having a gingival head portion extending mesially-distally 328, a pair of opposing directed arm portions 350 and 352, and mesial and distal ends in free rotation defining laterally spaced tails 332 and 334 extending respectively from arms 350 and 352 and free ends 358, between them. Each of the tails 332 and 334 is pivotally received within a respective hole 336 and 338 formed in the respective ones of the occlusal tether fins 318. More particularly, the tails 332 and 334 are received inside the respective holes 336 and 338 along the outer surface the respective occlusal strapping fins (for example, the mesial side of the mesial-occlusal strapping fins and the distal side of the distal-occlusal strapping fin 318). In this specific embodiment, the locking clip 326 may include an inclined member 370, which extends lingually from the head portion 328 to define a forward protruding lip hook 372 and a lingual guide portion 374.
[00149] Retaining member 327 can be provided in the first bridge portion 360 and desirably includes a first opening 364 in the labial face of the first bridge portion 360 and a second opening 366 in the gingival face of the first bridge portion 360. Desirably, the first opening 364 and the second opening 366 define a through hole 362 between them to receive the inclined member 370 to hold the locking clamp 326 in the closed position.
[00150] The second opening 366 in the gingival surface of the bridge portion 360 includes a lingual flange 368, which engages the lip hook 372 when the locking clamp 326 is in the closed position. The engagement between the flange 368 and the lip hook 372 keeps the locking clamp in the closed position while retaining the locking clip 326 against the orthodontic wire thereby inhibiting the relative movement between the orthodontic wire and the body 312 of the orthodontic bracket 310. For close the orthodontic bracket 310, the locking clamp 326 is pivoted around the tails 332 and 334 towards the first bridge portion 360. As the lingual guide 374 contacts the gingival edge 376 of the first opening 364, the inclined member deviates (by example, inclines) occlusally thereby allowing lingual guide 374 to pass through through hole 362.
[00151] Desirably, the lingual guide 374 is provided at the free end of the inclined member 370 and includes a portion that is configured to direct the inclined member 370 within the first opening 360 and into the through hole 362. It is assessed that the guide portion it may be curved, arched, angled, flat, or otherwise formed to assist in directing the inclined member 370 to the closed position.
[00152] The reaction force applied to the gingival edge 376 of the first opening 364 by the lingual guide 374 causes the inclined member 370 to deviate (for example, occlusally) thus allowing the lip hook 372 to pass through the first opening 364 and to inside the through hole 362 between the open and closed positions. When the hook portion 372 is pivoted lingually beyond the flange 368 in the through hole 362, the inclined member 370 will quickly return to its unstressed state and the lingual hook 372 engages the flange 368 of the through hole 362 to its closed position. Inclined member 370 in this condition (e.g., unstressed state) inhibits locking clamp 326 from moving back to the open position. In this way, the groove of the orthodontic wire 320 remains closed thereby holding the orthodontic wire in the groove of the orthodontic wire.
[00153] At least one lip face of the gingival rib fins 316 and the bridge portion 360 may include a groove 380 having a complementary shape for receiving a portion of the locking clip 326 (e.g., head portion 328) while in position closed. It is considered that the groove 380 can be configured with an angled or curved portion to assist in directing the lingual guide 374 of the inclined member 370 at the first opening 364. Desirably, the labial faces of the gingival rib fins 316 (along the groove of the orthodontic wire) and the bridge portion 360 extending between them include the groove 380 having a generally semicircular cross section.
[00154] To release the orthodontic wire, the lingual guide 374 is moved (for example, pushed) generally occlusally through the second opening 366 and into the through hole 362 so that the hook portion 372 moves occlusally beyond the flange 368 thereby disengaging the hook 374 from flange 368. Thereafter, the inclined member 370 can be removed from the retaining member 327 through the first opening 364 and the locking clamp 326 is free to rotate around the tails 332 and 334.
[00155] Referring now to FIGS. 28H-28l, another embodiment of a self-ligating orthodontic bracket is shown and is generally indicated by reference number 410. In this embodiment, bracket 410 may comprise a rectangular body 412, a base 414, and a locking mechanism. locking including a locking clip 426 and a retaining member 427. The body 412 may include gingival banding fins 416 and occlusal banding fins 418 with an orthodontic wire groove extending mesially-distally 420 between them. A first bridge portion 460 and a second bridge portion 461 are provided in the region between the fins 424, with the first bridge portion 460 spanning between the gingival bandage fins 416 and the second bridge portion 461 spanning between the banding fins occlusals 418. More particularly, the first bridge portion 460 extends from the lip surface of the orthodontic wire groove to the lip surface of the gingival rib fins 416 while the second bridge portion 461 extends only partially to the lip surface of the gingival fins. occlusal anchorages 418.
[00156] The body 412 may also include an internal vertical slot 425 that extends occlusally-gingivally (for example, generally transverse to the groove of the orthodontic wire 420) through the body 412.
[00157] Locking clamp 426 may be in the form of a spring element generally in the form of a U having a gingival head portion extending mesial-distally 428, a pair of opposing arm ends 458 and mesial and distal in free rotation defining the laterally spaced tails 432 and 434 respectively extending from the arms 450 and 452. Each of the tails is pivotally received within a respective hole 436 and 438 formed in that respective one of the occlusal anchoring fins 418. More particularly, tails 432 and 434 are received into the respective holes 436 and 438 along the outer surface of the respective occlusal strapping fins (for example, the mesial side of the mesial-occlusal strapping fin 418 and the distal side of the distal strapping fin occlusal 418). In this embodiment, the locking clip 426 may include a pair of spaced-out inclined members 470a and 470b, which extend lingually from the head portion 428 to define the respective labial hooks that protrude mesially and distally 472a and 472b and the respective lingual guide portions 474a and 474b.
[00158] Retaining member 427 is provided around the gingival banding fins 416. More particularly, each gingival banding fin 416 extends out of the gingival surface of the body 412 to define a flange 468 that engages the respective lip hooks 472a and 472b when locking clip 426 is in the closed position. The engagement between the flanges 468 and the lip hook 472a, 472b keeps the locking clip 426 in the closed position, thereby retaining the locking clip 426 against the orthodontic wire in order to inhibit the relative movement between the orthodontic wire and the body 412 of the orthodontic bracket 410.
[00159] To close the orthodontic bracket 410, the locking clip 426 is pivoted around the tails 432 and 434 in the direction of the locking mechanism 427 around the gingival strap fins 416. The tongue guides 474a and 474b contact the labial surfaces of the respective gingival banding fins 416 so that the curved free ends 482 of the lingual guides 474a and 474b are guided inwardly along the respective internal surfaces of the gingival banding fins 416. In doing so, the inclined members 470a, 470b are offset one to the other so that they can be positioned within the region between the fins 424 between the gingival strap fins 416 as the locking clip 426 is pivoted to the closed position. The lingual guides 474a and 474b continue to be guided along the inner surfaces of the gingival strap fins 416 until the lip hooks 472a and 472b are positioned below the flanges 468 of the locking mechanisms 427a and 427b. This allows the inclined members 470a and 470b to quickly return to their unstressed state so that the lip hooks 472a and 472b engage the flanges 468 thereby maintaining the locking clip 426 in the closed position.
[00160] More particularly, the reaction force applied to the labial and internal surfaces of the gingival fin fins 416 by the lingual guides 474a and 474b causes the inclined members 470a and 470b to deviate (for example, mesially or distally inward) allowing this so that the lip hooks 472a and 472b pass within the reduced opening 448 of the region between the fins 424 between the open and closed positions. When lingual guides 474a and 474b are pivoted lingually beyond flanges 468, the angled members 470a and 470b will rapidly return to their unstressed state and lingual hooks 472a and 472b engage flanges 468 of retaining members 427a and 427b in their position closed. The inclined members 470a and 470b in this condition inhibit the locking clamp 426 from moving back to the open position. In this way, the groove of the orthodontic wire 420 remains closed thereby holding the orthodontic wire in the groove of the orthodontic wire.
[00161] To release the orthodontic wire, the inclined members 470a and 470b (for example, the lingual guide portions 474a and 474b) are generally pushed towards each other (for example, mesial-distally) to disengage each lip hook 472a and 472b of the respective flange 468. Thereafter, the angled members 470a and 470b can be removed (for example, labially) from the flanges 468 of the retaining member 427 so that the locking clip 426 is free to pivot around the tails. 432 and 434.
[00162] In this specific embodiment, the head 428 of the locking clip 426 extends gingivally beyond the first bridge portion 460. The lip surface of the gingival rib fins 416 may include a groove 480 having a complementary shape for receiving a portion locking clip 426 (e.g., head portion 428) while in the closed position. It is considered that groove 480 can be configured with an angled or curved portion to assist in maintaining locking clip 426 in the closed position. Desirably, the labial faces of the gingival rib fins 316 include the groove 480 having a generally semicircular cross section, which can be complementary to the locking clip 426.
[00163] Referring now to FIGS. 28J-28K, another embodiment of a self-ligating orthodontic bracket is shown and is generally indicated by reference number 510. The bracket 510 may comprise a body 512, a base 514, and a locking mechanism including a locking clamp. 526 and a retaining member 527. The body 512 may include gingival bandage fins 516 and occlusal bandage fins 518 with an orthodontic wire groove extending mesially-distally 520 between them. A first bridge portion 560 and a second bridge portion 561 are provided in the region between the fins 524, with the first bridge portion 560 transposing between the gingival strap fins 516 and the second bridge portion 561 transposing between the ligation fins occlusal 518. It is estimated that the first and second bridge portions 560 and 561 can extend from the lip surface of the orthodontic wire groove to the lip surfaces of the respective anchorage fins 516 and 518 thereby defining a portion of the gingival and occlusal walls of the groove of the orthodontic wire between the respective fins of gingival and occlusal ligation.
[00164] In this embodiment, the locking clamp 526 is in the form of a spring element having a generally cruciform contour. Locking clamp 526 may include a gingival head 528 having a lingual-gingivally protruding hook 572 and a lingual guide curve 574. Head 528 may be interconnected with a pair of opposing arms 550 and 552 (for example, portions of arm extending mesially and distally) extending through the groove of the orthodontic wire 520 to the free ends of the arm 558. It is estimated that arms 550 and 552 at least partially or substantially can extend in a parallel manner with the groove of the orthodontic wire 520. Each arm 550 and 552 can form a generally U-shaped configuration having a gingival portion extending to an occlusal portion with the free end of the arm 558 between them.
[00165] Locking clamp 526 may also include opposing free ends (for example, extending generally mesial and distal, although not required) that are curved to define separately spaced opposing tail ends 532 and 534 respectively. Each of the tail ends 532 and 534 is received in a respective hole 536 and 538 formed in one of the occlusal strapping fins 518 in an occlusal opening 596 in a lingual portion of the body 512.
[00166] Retaining member 527 includes a mesial-distally directed lip member 590 which extends between the gingival ligament fins 516 in a generally parallel relationship to the first bridge portion 560 to define a first opening 564. The member lip 590 includes a lingual flange 568 that engages hook 572 when locking clip 426 is in the closed position. The engagement between the flange 568 and the hook 572 holds the locking clamp 526 in the closed position so that the locking clamp 526 is retained against the orthodontic wire thereby inhibiting the relative movement between the orthodontic wire and the orthodontic bracket body 512 510.
[00167] To close the orthodontic bracket 510, the locking clip 526 is pivoted around the tails 532 and 534 in the direction of the locking mechanism 527 (for example, lip member 590) around the gingival fin fins 516. The guide lingual 574 contacts the labial-occlusal surfaces of labial member 590 so that hook 572 is guided occlusally along the inner occlusal surface of labial member 590. In doing so, head 528 is occlusally deflected towards the first bridge portion 560 of so that the head 528 can be positioned inside the first opening 564 between the gingival strap fins 516 as the locking clamp 526 is pivoted to the closed position. The lingual guide 574 is continuously guided along the inner occlusal surface of the lip member 590 until the free end 584 of the hook 572 is positioned below the flange 468 of the lip member 590. This allows the inclined member 570 to quickly retract into its unstressed state so that hook 572 engages flange 568 thereby maintaining locking clamp 526 in the closed position.
[00168] More particularly, the reaction force applied to the occlusal-internal surface of the lip member 590 by the lingual guide 574 causes the head 528 to deviate (for example, occlusally) thus allowing the hook 572 to pass inside the first opening 564 between open and closed positions. When the lingual guide 574 is pivoted (lingually-gingivally) beyond the flange 568, the locking clamp 526 will quickly return to its unstressed state so that the hook 572 engages the flanges 468 thereby preventing the removal of the hook 572 from the flange 568 and the first opening 564 during its closed position. Head 528 in this condition inhibits locking clamp 526 from moving back to the open position. In this way, the groove of the orthodontic wire 520 remains closed thereby holding the orthodontic wire in the groove of the orthodontic wire.
[00169] To release the orthodontic wire, the head 528 (for example, the hook 572) is pushed lingually and occlusally to disengage the hook 572 from the lip member 590. After that, the inclined members 570 can be removed from the lip member 590 and from the first opening 564 so that locking clip 526 is free to rotate around tails 532 and 534.
[00170] Optionally, the locking clamp 26 can also include a cover portion 90 as shown in FIG. 29A. The cover portion 90 defines a generally oval shape and may include a lip surface 92 which generally extends the length and width of the groove of the orthodontic wire when included. The cover portion 90 may also include a connecting member 94 for connecting to the locking clip 26. It is assessed that the connecting member 94 is positioned around the lingual surface 96 of the covering portion 90 and is of a size and shape complementary to that of the clamp opening 60. When included, the connecting member 94 engages the clamp opening 60 of the locking clamp 26 so that it is removably attached thereto. While in the closed position, it is assessed that the cover portion 90 substantially or entirely covers the groove of the orthodontic wire having the orthodontic wire in it so as to provide a bracket with a more aesthetic appearance. In addition, it is assessed that the cover portion 90 can help prevent the accumulation of food and / or pests in the bracket 10.

[00173] FIGS. 30A-30D are various views of another alternative embodiment of the self-ligating bracket shown in FIG. 28E where the bracket 210a may comprise a body 212a, a base 214a, and a locking mechanism including locking clip 226a and a retaining member 227a. Body 212a may include gingival strap fins 216a and occlusal strap fins 218a with a groove in the orthodontic wire extending mesially-distally 220a between them. In this specific example, the body 212a has a rectangular body and includes a first bridge portion 260a in the region between the fins 224a, which span between the gingival rib fins 216a. The first bridge portion 260a extends from the lip surface of the orthodontic wire groove 220a to the lip surface of the gingival ligament fins. The body 212a may also include a second bridge portion 261a in the region between the fins 224a, which transposes between the occlusal strap fins 218a. It is assessed that the second bridge portion 261a partially extends from the lip surface of the orthodontic wire groove 220a to allow rotation of the locking clamp 226a.
[00174] Locking clamp 226a may be in the form of a spring element generally in the form of a cross having curved mesial and distal free ends defining the laterally spaced tails 232a and 234a. Each of the tails is pivotally received within a respective hole 236a and 238a formed in those of the respective occlusal strap fins 218a.
[00175] Retaining member 227a is provided in the first bridge portion 260a and may include opposing stop assemblies 244a and 246a. More particularly, to close the orthodontic bracket 210a, locking clip 226a can be pivoted around tails 232a and 234a. As the locking clamp 226a is pivoted, the arms of the clamp 250a and 252a of the head portion 228a are pushed into the bridge portion 260a against the respective pairs of opposing stops 244a and 246a. The reaction force applied to the opposing stop sets 244a and 246a by the clamp arms 250a and 252a causes the clamp arms 250a and 252a and / or the opposing stops 244a and 246a to deform thereby allowing the clamp arms 250a and 252a pass through the reduced openings 248 between the open and closed positions. When the head of the clamp 228a is pivoted in addition to the opposing stop sets 244a and 246a, the clamp arms 250a and 252a, the opposing stops 244a and 246a, or a combination of both will quickly return to their unstressed state and the head 226a it is inclined towards the labial surface 219a close to the recesses 262a to its closed position below the respective sets of opposing stops 244a and 246a. The opposing stop assemblies 244a and 246a in this condition (e.g., unstressed state) inhibit the locking clamp 226a from moving back to the open position. In this way, the groove of the orthodontic wire 220a remains closed thereby holding the orthodontic wire (not shown) in the groove of the orthodontic wire 220a. In addition, the groove of the orthodontic wire may include a generally non-flat portion extending mesial-distally (e.g., a curved portion such as a concave portion or a convex portion and / or an angled portion). For example, a labially positioned bracket may include an orthodontic wire groove having a lingually directed base surface thereby forming a generally convex portion of the orthodontic wire groove or a lingually positioned bracket may include an orthodontic wire groove having a labially based surface. directed thus forming a generally concave portion of the groove of the orthodontic wire, although not required. More particularly, the orthodontic wire groove may include a lingually directed portion that also extends along the mesial-distal direction to define at least a non-flat portion of the orthodontic wire groove. Desirably, a curved and / or angled 720a orthodontic wire with a curved and / or angled 721a lip surface can provide a more aesthetic looking bracket having a low profile. •.
[00176] Referring now to FIGS. 30E-30L, additional embodiments of a self-ligating orthodontic bracket are shown and are generally indicated by reference numbers 710 (710a, 710b, 710c, and 710d). Orthodontic brackets 710a and 710b are generally similar to the embodiment of FIGS. 28A-28B, while orthodontic brackets 710c and 710d are generally similar to the embodiments of FIGS. 28H-281. However, these embodiments are not limiting and it is appreciated that any of the brackets described herein or otherwise may include a groove in the orthodontic wire having a generally non-flat portion extending mesial-distally (e.g., a curved portion such as a concave portion or a convex portion and / or an angled portion). For example, a labially positioned bracket may include an orthodontic wire groove having a lingually directed base surface thereby forming a generally convex portion of the orthodontic wire groove or a lingually positioned bracket may include an orthodontic wire groove having a labially based surface. directed thus forming a generally concave portion of the groove of the orthodontic wire, although not required.
[00177] More particularly, the groove of the orthodontic wire may include a lingually directed portion that also extends along the mesial-distal direction to define at least a non-flat portion of the groove of the orthodontic wire. Desirably, a curved and / or angled 720 orthodontic wire with a curved and / or angled 721 lip surface can provide a more aesthetic appearance bracket having a low profile with a vertical slit 725 (FIGS. 30E-30F and 301-30J or a very low profile without the vertical slot 725 (FIGS 30G-30H and 30K-30L) .It is estimated that the groove of the orthodontic wire may extend mesial-distally in a generally parallel manner in relation to the lingual surface of the base, to the labial surface of the base, the labial surface of the tooth, or otherwise, although not required.
[00178] A portion of the groove of the orthodontic wire can be lingually directed to the base 714 in relation to at least a labially directed portion of the groove of the orthodontic wire. More particularly, the at least one labially directed portion may include an apex portion 796 that is labially compensated or displaced with respect to at least one other mesial-distally located portion of the orthodontic wire groove (for example, mesial and distal ends 794 of the 720 orthodontic wire slit). It is estimated that the groove of the orthodontic wire may include a radius of constant curvature or taper along its mesial-distal length; however, a variable radius of curvature or variable taper is also considered. Desirably, apex portion 796 may be provided in a central portion of the orthodontic wire slot (e.g., region between fins 724). Preferably, the apex portion 796 is provided midway through the groove of the orthodontic wire, such that the gap in the orthodontic wire is symmetrical as shown in the cross sections of FIGS. 30F, 30H, 30J, and 30L. However, it is assessed that the apex portion 796 may be provided at various locations along the groove of the orthodontic wire from the mesial end to the distal end or may be provided at one of the mesial and distal ends 794. In addition, it is also assessed that the groove of the orthodontic wire may include a generally flat portion in the region between the fins while having lingually directed end portions which may be angled and / or curved with respect to the central (e.g., intermediate) flat portion.
[00179] As mentioned above, the base surface of the orthodontic wire groove may also include a concave portion. When included, a portion of the base surface of the orthodontic wire groove can be labially directed out of the bracket base relative to another portion of the base surface of the orthodontic wire groove. This can be done along a curve or in an angled way. In addition, as discussed above, any curved and / or angled portion of the base surface of the orthodontic wire groove can be positioned along one or more portions along the base of the orthodontic wire groove (for example, in a portion of edge, in the opposite edge portion, in a central portion, or between or elsewhere along the base surface of the crevice of the orthodontic wire.
[00180] FIGS. 31A-31D are various views of an alternative embodiment of the self-ligating dental bracket shown in FIGS. 9A-9G in which the lingual free end 1028s pivotally engages a lingual opening 1064s formed in the lingual portion of the open stop groove 1042s. In this specific embodiment, the locking clip 1026s can include a generally J-shaped configuration and include deformable fingers 1062s having flange portions 1066. Once received in the lingual cavity, the deformable fingers can remain in a partially stressed state due to to the active engagement of the outer edges 1070s of the flange portions with the respective walls on the mesial and distal inner sides 1136s of the occlusal anchoring fins 1018s to assist in suppression of movement (eg, oscillation, mesial-distal movement, and / or other locking clamp 1026s while in the closed position. In addition, this active gearing also allows rotation of the lock and / or fixation of the locking clamp to the bracket body.
[00181] It is assessed that the locking clips described herein can be formed from a superelastic member such as a nickel-titanium alloy, even if the locking member has been deformed relatively extreme, there is no large variation in the load, and the orthodontic wire can be pressed down moderately under superelasticity. In addition, the favorable operating efficiency in the treatment operation can be maintained. For example, wires ranging from a narrow round wire to a square wire of normal size can be pressed into the slot with a virtually equivalent load, and three-dimensional control is possible starting from an initial treatment period with an ideal force on the living body. In addition to the restoration force of the wire, the correction force is also produced by the force with which the locking member presses down the orthodontic wire, and higher dimensionality treatment is possible.
[00182] In a specific example, the locking clamp can be formed of an alloy comprising 35 to 55 (for example, 40 to 50)% by weight of Co, 10 to 30 (for example, 15 to 25)% by weight Ni, 10 to 30 (for example, 15 to 25)% by weight of Cr, 0.5 to 15 (for example, 1 to 10)% by weight of Fe, 0.01 to 15 (for example, 0, 1 to 10)% by weight of W, 0.01 to 15 (for example, 0.1 to 10)% by weight of Mo, and / or 0.01 to 10 (for example, 0.1 to 5)% by weight of Ti.

3) design of pressure lock that locks the locking clamp in place using the cavity in the bracket body that holds the locking clamp in place, 4) locking design with a centrally located locking mechanism that compresses when pushed into the slit of the body before expanding into the locked position in the open body cavity and 5) snap-in design with two laterally located locking mechanisms that compress when pushed into the chamfers before expanding into the locked position when the mechanism transposes the chamfer; the ideal rotational control of the orthodontic wire as the locking clamp can be extended as mesially or distally as necessary without affecting the locking clamp / body assembly mechanism; the locking clamp crosses the full width (for example, of the orthodontic wire groove) of the bracket base while engaging the wire, thus providing maximum possible torque; low friction in the system as there will be two points of contact between the locking clamp and the orthodontic wire (gingival and occlusal corners at the mesial and distal ends of the orthodontic wire) as opposed to the continuous line of contact along the only gingival portions or occlusal portions orthodontic wire; the groove of the orthodontic wire can be designed with at least one protrusion (for example, a plurality of protrusions) and / or at least one groove (for example, a plurality of grooves) in the bottom and / or side walls to minimize the area of contact between the orthodontic wire and the groove of the orthodontic wire, (to optionally express the torque incorporated in any wire size);
