    Description [0001] The present invention relates to a bite. The invention can also find application in a device known as "flat bite". The bite is an orthodontic appliance intended to be interposed between the lower and upper dental arches of a user to modify their mutual positioning.
    [0002] Orthodontic appliances or appliances are known to reduce the damage caused by incorrect positions of the dental arches, or to reduce the effects deriving from other problems such as bruxism or teeth grinding. In general, incorrect positions of the dental arches cause tensions to the muscles of the face, neck and oral cavity (tongue muscles), on which essential processes such as chewing, swallowing and articulation of sounds depend. These muscular tensions are particularly undesirable as they can compromise the aforementioned processes. Furthermore, the muscles of the face, neck and oral cavity also act on the vertebral column and therefore their tension determines stresses from which an incorrect alignment of the vertebral column can result and therefore problems of posture, balance and gait.
    [0003] In order to re-educate the position of the dental arches, the known bites operate on the relative position of the dental arches.
    [0004] However, known bites do not guarantee a high efficacy in the re-education of the position of the dental arches and in postural re-education.
    [0005] Furthermore, the known bites do not allow to precisely control and define the positioning of the jaw of the user.
    [0006] Furthermore, the known bites do not allow to sufficiently reduce the known problems in terms of muscular tensions, postural imbalances, bruxism, etc.
    [0007] In this context, the main object of the present invention is to solve one or more of the problems found in the known art.

    [0057] With reference to the figures, the number 1 indicates a bite in accordance with the present invention. Under conditions of use, the bite 1 is intended to be engaged within the oral cavity of a user or patient in such a way as to determine a correct relative position between the upper dental arch and the lower dental arch, as will be described in greater detail below.
    [0058] The bite 1 comprises a lower portion 2, a central portion 3 and an upper portion 4. The bite 1 further comprises a positioning element 7, 21 of at least one dental arch of the user; in the embodiments from the first to the fifth, the positioning element is constituted by an abutment ridge 7, while in the sixth and in the seventh embodiment the positioning element is constituted by an invitation portion 21.
    [0059] The embodiments from the first to the fifth of a bite in accordance with the present invention are now described. In accordance with these embodiments, the lower portion 2 is at least partially counter-shaped to the lower dental arch of the user and can comprise a housing seat 20 for the lower dental arch (see Fig. 9-11). The central portion 3 develops between the lower portion 2 and the upper portion 4, which can be provided with a plurality of through holes 5 or through channels 6 intended to place the cavity in communication, in conditions of use of the bite 1, oral examination by the user with the external environment to allow air to pass through.
    [0060] The upper portion 4 comprises a contrast ridge 7 in correspondence with which, in conditions of use of the bite 1, the front surfaces of the teeth of the upper dental arch are destined to abut. The contrast ridge 7 is vertically aligned or retracted with respect to the lower portion 2; this positioning of the contrast ridge 7 allows the upper arch of the user to position himself, in conditions of use of the bite 1, in a position aligned or set back with respect to the lower dental arch. Figure 11 illustrates, for example, a bite 1 whose abutment ridge 7 is substantially aligned with the lower portion 2 and consequently, as illustrated, in use conditions of the bite 1, the upper dental arch of the user is substantially aligned with the lower dental arch. When inserting the bite 1 into the oral cavity, the user positions the lower portion 2 of the bite 1 in correspondence with the lower dental arch; to allow the positioning of the upper dental arch against the crest 7, the jaw of the user slides forward with respect to the maxilla. At this point, the user positions the teeth of the upper dental arch against the check ridge 7 by means of an appropriate relative protrusive movement between the maxilla and mandible. In the conditions of use of the bite 1, at least the incisors of the user are in abutment on the contrast ridge 7. The contrast ridge 7 therefore acts as a limit stop for the teeth of the upper dental arch, consequently allowing the correct positioning of the upper dental arch than the lower dental arch. Advantageously, in order to allow an ergonomic feedback for the upper dental arch of the user, the contrast ridge 7 can be at least partially counter-shaped with respect to a plurality of teeth of the upper dental arch.
    [0061] As described below with reference to some embodiments of the present invention, the contrast ridge 7 can be fixed or movable with respect to the lower portion 2.
    [0062] In fig. 1-2 a first embodiment of the bite 1 is shown. The bite 1 in accordance with the first embodiment is made in a single piece in resin and the contrast ridge 7 is fixed with respect to the lower portion 2.
    [0063] In fig. 3-4 shows a second embodiment of the bite 1. The bite 1 in accordance with the second embodiment comprises an arched containing portion 8 intended, under conditions of use of the bite 1, to contain the language of the user. In other words, in conditions of use of the bite 1, the user's language is positioned below the arched containment portion 8. This positioning prevents the tongue from moving from the normal lowered position to a raised position, as can generally happen when the user is in a supine position (for example in resting conditions) and therefore prevents the tongue from going to occlude Toro-pharynx of the user. Such a displacement of the tongue can cause, as we know, sleep apnea and snoring (or snoring). In light of this, providing a containment portion 8 of the tongue makes it possible to eliminate or reduce sleep apnea and snoring.
    [0064] The tongue-containing portion 8 may be provided with through openings 9 which, in use by the bite 1, put in communication a lower portion of the user's oral cavity with an upper portion of the oral cavity, allowing for example the passage of saliva. As illustrated in figs. 3 and 4, the bite 1 in accordance with the second embodiment further comprises abutment elements 10 arranged laterally at the lower portion 2 and protruding with respect thereto. Under the use of the bite 1, the restraining elements 10 are in contact with one or more teeth of the lower dental arch of the user to determine their correct positioning with respect to the lower portion 2 and limit undesired movements of the lower dental arch of the 'user. The abutment elements 10 can be made of metallic material. Preferably, the abutment elements 10 are at least partially embedded in the lower portion 2. According to the second embodiment, the contrast ridge 7 is fixed with respect to the lower portion 2; preferably, the lower portion 2, the central portion 3 and the upper portion 4 are made of a single piece of resin.
    [0065] Fig. 5-6 and fig. 7-8 illustrate respectively a third and a fourth embodiment of the bite 1. The bite 1 in accordance with the third and fourth embodiment comprises the containing portion 8 of the tongue (as in the second embodiment) and a fixed ridge 11 arranged frontally and externally with respect to the contrast ridge 7. In accordance with the third and fourth embodiments, moreover, the contrast ridge 7 is of the movable type with respect to the lower portion 2 and with respect to the fixed ridge 11. In particular, the ridge abutment 7 can slide posteriorly with respect to the fixed ridge 11 so as to operate between a plurality of positions set back with respect to the lower portion 2. The backward positions are defined at a different distance from the fixed ridge 11 and define, in conditions of use of the bite 1, a plurality of possible rearward positioning of the upper dental arch of the user with respect to the inferior dental arch hours. For example, when the contrast ridge 7 is positioned in close proximity or of maximum proximity to the fixed ridge 11, in use conditions of the bite 1 the teeth of the upper dental arch can be aligned vertically with the teeth of the lower dental arch, while progressively moving the contrast ridge 7 to the rear position, the teeth of the upper dental arch assume a position that is increasingly backward with respect to the teeth of the lower dental arch. Different relative positions of the upper and lower dental arches obviously correspond to different relative positions of the jaw of the user with respect to the maxilla. As the distance between the mobile ridge 7 and the fixed ridge 11 increases, the extent of the sliding movement of the jaw of the user with respect to the maxilla increases accordingly. The extent of the protrusive sliding movement of the jaw can be determined and set (by the relative spacing between the fixed ridge 11 and the movable ridge 7) according to the specific needs of the user; these needs can be related to postural re-education and / or re-education of the position of the jaw of the user.
    [0066] In order to be able to move with respect to the lower portion 2, the contrast ridge 7 comprises lateral sliding portions 12 at least partially housed in correspondence with lateral guide portions 13 of the bite 1 (see Fig. 12). When the contrast ridge 7 is moved, the lateral sliding portions 12 can slide inside the lateral guide portions 13. The sliding of the contrast ridge 7 is managed by a regulator 14, which can operate between a configuration of adjustment in which it allows the adjustment of the position of the contrast ridge 7 by sliding of the side portions 13 and a fixing configuration in which it does not allow the adjustment of the position of the contrast ridge 7. The regulator 14 can for example comprise one or more elements of adjustment 140 threaded (see Fig. 9-10), such as one or more worm screws, configured to manage the position of the checking ridge 7. In other words, the actuation of the regulator 14 acts on the threaded adjustment elements 140, that operate on the control crest 7 to determine their displacement. By managing the positioning of the contrast ridge 7, the regulator 14 allows to adapt the bite 1 to the specific needs of the user. In figs 9 and 10 show two different operative positions of the checking ridge; in particular, in fig. 9 shows a close position of the abutment ridge 7 with respect to the fixed ridge 11, while in fig. 10 shows a position further back than the reference ridge 7 with respect to the fixed ridge 11. Starting from the position of the contrast ridge 7 of fig. 9, the position of fig. 10 can be reached by working on the threaded adjustment elements 140.
    [0067] The bite 1 in accordance with the third and fourth embodiments further comprises an appendix 15 arranged at a front portion of the bite 1 and provided with a plurality of through channels 6. The through channels 6 are intended to put in communication, in conditions of use of the bite 1, the oral cavity of the user with the external environment to allow the passage of air. In conditions of use of the bite 1, appendix 15 is placed between the user's lips and provides a support for the lips themselves (see fig. 9 and 10).
    [0068] In the fourth embodiment the contrast ridge 7 is made of metallic material, while in the third embodiment the contrast ridge 7 comprises a metal skeleton 16 covered in resin. According to the third and fourth embodiments, the upper portion 4, the central portion 3 comprising the appendix 15, the lower portion 2 and the containing portion 8 of the tongue can be made in a single piece of resin.
    [0069] In accordance with the third embodiment, as illustrated in figs. 5 and 6, the bite 1 can also comprise abutment elements 10 (substantially like those of the type provided in the second embodiment) configured to determine the correct positioning of the lower portion 2 with respect to the lower dental arch.
    [0070] In figs 13 and 14 show a bite 1 in accordance with a fifth embodiment of the present invention. The bite 1 in accordance with the fifth embodiment comprises the containing portion 8 of the tongue and the abutment ridge 7 movable with respect to the lower portion 2. Unlike the third and fourth embodiments, the bite 1 in accordance with the fifth form embodiment does not provide a fixed ridge 11. The contrast ridge 7 is integral with the lateral sliding portions 12, which can slide inside the lateral guide portions 13. The position of the feedback ridge 7 is managed by actuating an element fixing device 17. The fixing element 17 comprises a threaded fixing dowel 18, which is configured to act on the lateral sliding portions 12 and can be operated to inhibit its sliding (thus blocking the displacement of the check ridge 7) or to allow it to slide (allowing the comparison crest to be moved 7).
    [0071] In an alternative embodiment, a metal or ferrule frame can also be provided, for example constituted by a suitably shaped metal wire, engaged to the lower portion and adapted to define a plurality of anchoring areas to the lower dental arch of a user, in so as to increase the stability and precision of the position of engagement of the bite to the lower arch of the user. A sixth and a seventh embodiment of the bite 1 according to the present invention are now described. According to these embodiments, the upper portion 4 is at least partially counter-shaped to the upper dental arch of the user and can comprise a housing seat 40 for the upper dental arch (see Fig. 20-22). The housing seat 40 is adapted to allow a stable engagement of the teeth of the upper dental arch to the bite 1, so as not to allow, in operative conditions, an unwanted displacement of the bite 1 inside the oral cavity. The lower portion comprises an invitation portion 21 which allows a determined relative positioning between the jaw of the user, which will be described in greater detail below.
    [0072] The invitation portion 21 extends transversely with respect to a front portion of the bite 1 and has an inclined surface 22 which extends away from the front portion of the bite 1. The development of the invitation portion 21 is clearly shown in Fig. 19. The invitation portion 21 is preferably integral with the lower portion 2.
    [0073] When inserting the bite 1 into the oral cavity, the user positions the upper portion 4 of the bite 1 in correspondence with the upper dental arch; to position the lower dental arch, the invitation portion 21 guides the lower dental arch making it slide towards the front portion of the bite 1. In this way, the invitation portion 21 allows the sliding of the user's jaw forward with respect to to the jaw. At this point, that is to say at the end of the advancement of the mandible, the teeth of the lower dental arch of the user are positioned frontally with respect to the invitation portion 21 and the posterior surfaces of one or more teeth of the lower dental arch are at least partially in contact with the invitation portion 21. The bite 1 therefore allows an appropriate relative protrusive movement between the jaw and mandible.
    [0074] In accordance with the sixth embodiment, the lower portion 2 is movable with respect to the upper portion 4. Moving the upper portion 4 and the lower portion 2 with respect to one another, the position of the invitation portion 21 is modulated with respect to the upper portion 4. Furthermore, the extent of the protrusive sliding movement of the jaw can be determined and set (by the relative spacing between the invitation portion 21 and the upper portion 4) according to the specific needs of the user; these needs can be related to postural re-education and / or re-education of the position of the jaw of the user.
    [0075] To enable reciprocal movement between upper portion 4 and lower portion 2, the upper portion 4 is equipped with lateral guide portions 13, which act as rails inside which sliding side portions 12 of the lower portion can slide. 2. According to a variant (not shown in the figures), the lateral guide portions 13 can be arranged on the lower portion 2 and the lateral sliding portions 12 can be arranged on the upper portion 4. The lateral guide portions 13 and the side sliding portions 12 can be constituted by inserts of metallic material integrated in the material (preferably plastic) in which the lower portion 2 and the upper portion 4 are made. According to a variant, the lateral guide portions 13 and the side portions of sliding 12 can be shaped portions of the same material (preferably plastic) in which they are made the lower portion 2 and the upper portion 4. The joint 1 can furthermore comprise adjustment means 23 configured to allow adjustment of the mutual position between the invitation portion 21 and the upper portion 4.1 adjustment means 23 can be of the threaded type and can comprise an adjustment screw, for example a worm screw, of the position of the invitation portion 21 (see figs. 19 and 22). As illustrated in fig. 22, the adjustment means 23 can be arranged at the central portion 3 of the bite 1 and can be accessed (to make an adjustment) from a front portion of the bite 1.1 adjustment means 23 are further configured to allow the locking of the portion of invitation 21 in a certain position.
    [0076] The bite 1 can also comprise position indicators 24 configured to indicate the mutual position between the lower portion 2 and the upper portion 4. The position indicators 24 are arranged both on the upper portion 4 and on the lower portion 2 of the bite 1 in correspondence of side portions of the same bite (see figure 16). In practice, even just by displaying the reciprocal position of the position indicators 24 of the lower portion 2 and of the upper portion 4, it is possible to determine the position of the invitation portion 21 with respect to the upper portion 4. According to the seventh embodiment, the portion lower 2 is fixed with respect to the upper portion 4. In other words, in the seventh embodiment the invitation portion 21, which is integral with the lower portion 2, cannot move relative to the upper portion 4. For example, the bite 1 can be made in a single piece, preferably in plastic. The sixth and the seventh embodiments may have additional features in common, which are described below. The invitation portion 21 of the bite 1 can develop for a width substantially equal to the extension of the lower dental arch of the user, in such a way as to simplify the sliding forward of the jaw and allow, under operating conditions of the bite 1, a optimal support of a plurality of teeth of the lower dental arch. In accordance with a variant not shown in the accompanying figures, the invitation portion 21 can develop only for a limited width, substantially equal for example to a central portion 3 of the lower dental arch of the user corresponding at least to the position of the incisors and the canines.
    [0077] The bite 1 can have a deformable or soft portion 25, which can have a substantially gelatinous consistency. The deformable portion 25 has a lower hardness than the lower portion 4 and is applied frontally to the lower portion 4. The deformable portion 25 provides a comfortable support for the rear surfaces of the teeth of the lower dental arch of the user and can deform to assume a profile corresponding to the shape of the teeth themselves.
    [0078] The deformable portion 25 is engaged to the lower portion 2 in correspondence with one or more through holes 26 of the invitation portion 21, inside which protuberances 27 of the deformable portion 25 which keep it engaged are developed. to the invitation portion 21. Alternatively, the deformable portion 25 can be engaged to the invitation portion 21 by means of adhesive substances or other mechanical coupling means.
