    [0002] Technical field
    [0003] The present invention concerns an adjustable calcinable abutment for the manufacture of a superstructure, the method of manufacturing a metal superstructure, within the field of manufacturing dental prostheses.
    [0004] State of the art
    [0005] It is known in the state of the art the use of calcinable abutments for the modeling of superstructures by means of the lost wax method which consists, first, of the addition of calcinable material (typically wax) of coating on said calcinable abutment, and / or by means of the removal of parts of the calcinable pillar. Second, once the superstructure model is obtained, said model is wrapped in refractory molding material and introduced into a preheating furnace at a temperature of around 900 ° C to remove the calcinable material. Third, the molten metal is poured into the resulting cavity, thus obtaining the superstructure on which a typically ceramic coating is placed, thus obtaining a dental prosthesis.
    [0006] The calcinable abutment, and consequently also the obtained superstructure, has a hollow interior that defines a conduit accessible from the outside through an access opening through which a fixing screw that anchors the calcinable abutment can be introduced and screwed, or the superstructure, to a dental implant.
    [0007] The position and orientation of the calcinable abutment will therefore determine the aesthetics and shape of the metal superstructure and the dental prosthesis, as well as the position of the access opening through which the fixing screw is introduced, which preferably It should be in a non-visible area of the dental prosthesis once installed in the mouth.
    [0008] Therefore, and also due to the uncertain position of the initial dental implant, the adjustable calcinable abutments are also known that have a fixing base attached to a tubular wall through a tubular joint that allows to modify its orientation with respect to the orientation of the dental implant.
    [0009] A common solution is that of an adjustable abutment by means of a patella, such as that described in documents US4793808A, US4832601A, US5302125A. However, the ball joint solution requires placing a spherical surface above the abutment support base, the center of rotation of the abutment being the center of said sphere, which will be about millimeters above the fixing base. Therefore, a portion adjacent to the fixing base cannot correct its orientation, and only the most distal part thereof can correct its orientation.
    [0010] From US2007099151A1 a hollow pillar is also provided with cuts in its walls that allow bending, however, said cuts allow only bending in a single direction, in addition to assuming a weakening of said pillar and a possible entry of calcinable material inside the calcinable abutment that could make it difficult to insert or remove the fixing screw.
    [0011] Brief Description of the Invention
    [0012] The present invention concerns an adjustable calcinable abutment for the manufacture of a suprastructure, preferably of metal, of a dental prosthesis attached to a dental implant.
    [0013] It is understood that a dental prosthesis, typically composed of a ceramic material, is supported on a superstructure that is usually composed of a metallic material, which has a hollow interior through which a screw can be introduced and screwed so that it can fix said superstructure to a dental implant.
    [0014] The dental implant is an element, usually threaded, surgically implanted in the mouth of a patient receiving said dental prosthesis.
    [0015] The proposed calcinable abutment is a pillar intended to be fixed to a duplicate of the patient's denture, said duplicate including at least one dental implant analog (representing the dental implant with an exact replica of the interface between implant and calcinable) in identical position that the dental implant implanted in the patient.
    [0016] This allows an expert operator, who in this case will be a dental technician, to add calcinable material, for example wax, on the calcinable abutment and / or remove parts of the calcinable abutment until obtaining a model of the superstructure required to support a certain coating ( typically ceramic) adapted to a specific dental space of the patient.
    [0017] The superstructure model obtained from the calcinable abutment is coated with a refractory material and introduced into a preheating furnace at about 900 ° C, calcining the calcinable abutment and the calcinable material. Subsequently molten metal is poured inside filling the cavity left by the calcinable pillar and the calcinable material forming the metal superstructure that reproduces the shape of the wax-modeled superstructure model.
    [0018] Preferably, the metal superstructure will reproduce the shape of the desired dental prosthesis, but with a somewhat smaller size, between one and two millimeters smaller.
    [0019] The position and orientation of the initial calcinable abutment determines the position and size of the finally obtained metal superstructure, and also the position of the opening of the metal superstructure through which the fixing screw is placed. Said position and orientation of the calcinable abutment (traditionally straight) is in turn determined by the position and orientation of the dental implant.
    [0020] In order to correct the orientation of the calcinable abutment with respect to the dental implant, it is proposed that said calcinable abutment include, in a manner known per se:
    [0021]
    [0022] • a fixation base equipped with a first complementary coupling configuration with part of a dental implant or a dental implant analog intended for coupling the fixing base to the dental implant or the dental implant analog, and provided with a hole intern provided for the placement of a screw for fixing the calcinable abutment to the dental implant or the dental implant analog;
    [0023]
    [0024] • a hollow tubular wall made of calcinable material and connected to the fixing base, said tubular wall comprising a hollow tubular joint, adjacent to the fixing base, constituted by a succession of pairs of truncated conical rings joined in succession forming an accordion section , each pair of rings consisting of a first frustoconical ring and a second frustoconical ring in reverse orientation.
    [0025]
    [0026] • The through hole of the fixing base is provided for the placement of a fixing screw of the calcinable abutment to the dental implant or the dental implant analog, said through hole will preferably be surrounded by an inner annular seating surface arranged in a hollow interior of the calcinable abutment, intended to support the head of the fixing screw.
    [0027] Said first configuration of coupling of the fixing base will preferably be provided to be complementary to the head of the dental implant or to the head of the dental implant analog, that is to say that its geometry will allow a narrow and stable support.
    [0028] There are many geometries that can allow such narrow and stable support, although geometries that allow a partial insertion of the fixation base into the head of the dental implant or the dental implant analog, or vice versa, for example being part of the surface, will be preferred. external annular seat of truncated conical, cylindrical, truncated pyramidal or prismatic shape, insertable in said head, or defining said surface of outer annular seat a recess with one of the aforementioned geometries to which a portion of the head of the dental implant or the complementary dental implant analog equipped with said geometry can be inserted.
    [0029] Geometries that prevent a relative rotation between both elements will also be preferable, avoiding cylindrical or truncated conical geometries, or including anchors that prevent rotation.
    [0030] Despite the above, the use of other geometries, including non-regular geometries for this purpose, is also contemplated.
    [0031] The tubular wall and the tubular joint are hollow and allow the fixing screw to pass through it to be inserted through the through hole of the fixing base, so that a head of said fixing screw is supported on the surface of inner ring seat. When fixing the fixing screw to a dental implant or an analog of a dental implant, said fixing screw will clamp the fixation base against the dental implant or against the dental implant analog, so that the first base coupling configuration fixation will be in contact and pressed against the head of the dental implant or the dental implant analog, achieving a firm fixation of the calcinable abutment.
    [0032] The tubular joint allows to regulate the orientation of the tubular wall, or most of it, with respect to the fixation base, allowing to correct the direction of the calcinable abutment with respect to the direction of the dental implant, thus ensuring a correct alignment of the Dental prosthesis with the rest of the denture. This feature also allows the skilled operator to regulate the position of the opening of the calcinable abutment through which the fixing screw is introduced, and which determines the position of the metal superstructure, allowing said opening to be placed in a position not visible from the outside of the mouth
    [0033] The use of a succession of pairs of truncated conical rings forming an accordion section gives flexibility to the hollow tubular joint, allowing to modify its inclination and orientation at will.
    [0034] The present invention further proposes, in an unknown manner, that:
    [0035]
    [0036] • the first and second truncated cone rings are of a material and of a thickness selected to be elastically deformable, capable of recovering a stable position in the absence of external forces; and
    [0037]
    [0038] • the first frustoconical ring and the second frustoconical ring are asymmetric, so that the elastic force exerted by the stable positions of the first Truncated conical rings are different from those exerted by the stable positions of the second truncated conical rings, making the first truncated conical ring retain the second truncated conical ring in a non-stable position where the pair of truncated conical rings is collapsed only in one part , keeping the tubular joint (12) in a stable inclined position.
    [0039] Therefore, the invention proposes the use, for the manufacture of the tubular joint, of a material selected so that, by using it with a pre-established thickness, said material is elastically deformable, that is to say that it allows to modify its shape by applying an external force but that it recovers its initial geometry when this external force ceases. It is also proposed that the first frustoconical ring and the second frustoconical ring of each pair of frustoconical rings that constitute the accordion section of the tubular joint be different from each other, for example being the first frustoconical ring of a length greater than the second frustoconical ring .
    [0040] The use of an elastically deformable material would cause any deformation applied to the tubular joint due to an external force to be an unstable deformation, and therefore the calcinable abutment will recover its initial position when said external force disappears.
    [0041] However, the aforementioned asymmetry between the first and second truncated conical rings causes the elastic force of the first frustoconical rings to be greater than the elastic force of the second truncated conical rings, and therefore that in the absence of other external forces the elastic force of The first truncated conical rings can retain the second truncated conical rings in a different position than the initial one.
    [0042] This allows, after a deformation applied by an external force, the tubular joint is maintained in the new position when said external force disappears, maintaining the calcinable abutment in the inclined position desired by the technician who is producing the dental prosthesis.
    [0043] In an inclined position, parts of some of the second truncated conical rings will be inserted into the first truncated conical rings, collapsing only one side of the accordion section that defines the tubular joint causing its inclination to one side. Each first truncated conical ring will act as a zuncho or sash that will retain the part of the second truncated conical rings inserted inside, preventing it from coming out due to the elastic force of the material, retaining its shape.
    [0044] If the first and second truncated conical rings were symmetrical, the partial collapse of the accordion section would not cause the insertion of parts of the second truncated conical rings into the first truncated conical rings, but would simply cause the truncated conical rings to flatten in the form of overlapping discs. . When the external force was removed, the elastic properties of the material would cause the calcinable abutment to return to the initial position, typically the erect position, recovering all the truncated conical rings in their original form, making it difficult for the technician, who would have to block the calcinable abutment in the Inclined position desired by other means.
    [0045] Thus, each pair of truncated conical rings can be collapsed asymmetrically, that is, collapsing only on one side, and / or extending only on one side, determining a wedge that causes a rotation of the axis of the tubular wall. The accumulation of the turns produced by each pair of truncated conical ring allows to obtain considerable turns of the axis of the tubular wall.
    [0046] According to a proposed embodiment, at the junction between the first and second frustoconical rings, the thickness of the material is less than the thickness of the material in the first frustoconical ring and in the second frustoconical ring, weakening said joints that act as hinges.
    [0047] It is also contemplated that each first and second truncated cone ring is under tension, subjected to a prestress in an annular direction. This can be achieved, for example, by a manufacturing technique that deforms an initial tube to generate said first and second truncated cone rings. The deformation introduced will generate tensions within the material corresponding to said prestressing.
    [0048] The proposed solution allows the inclination of the tubular wall with respect to the fixing base of the calcinable abutment to start at a position very close to the latter, and not a few millimeters above as with other known systems. This represents a great improvement given the little existing space and the uncertain initial position of the dental implant also in height.
    [0049] According to one embodiment of the invention, the tubular wall, the tubular joint and the fixing base of the calcinable abutment are a single monobloc integral body, that is to say formed in a single piece, of calcinable material.
    [0050] This will allow the manufacturing of the superstructure by means of a casting technique in which the entire calcinable abutment will be calcined by molten metal that will replace it within a mold, obtaining a monolithic superstructure.
    [0051] It is also contemplated that the fixing base is a calcinable piece independent of and joined to the rest of the calcinable pillar, which is also made of calcinable material, allowing to obtain a monolithic superstructure when molten metal is poured.
    [0052] Alternatively, it is proposed that the fixing base be of non-calcinable material, such as metal, said non-calcinable fixing base being attached to the rest of the calcinable abutment. In such a case, the fabrication of the superstructure will require an over-casting technique in which the molten metallic material will calcine only the calcinable parts of the calcinable abutment and will be joined, when solidified, with the fixing base made of metal.
    [0053] The connection between the fixing base and the rest of the calcinable abutment can be carried out by means of a second coupling configuration provided in the fixing base and complementary to one end of the tubular wall. Said second coupling configuration will be provided for the fixing of the tubular wall to said fixing base, for example by means of a pressure adjustment, of an annular shoulder inserted in an annular groove, or another configuration that allows the tubular wall to be held together. to the fixing base. Furthermore, said coupling configuration can be both a removable fixation in one embodiment of the invention and allow a rotational movement between the tubular wall and the fixing base in another embodiment other than the invention.
    [0054] Said fixing base made of metal may be made, in a non-limiting manner, of a selected metal which, typically, is titanium, gold, palladium, chromocobalt alloy or chromium-nickel alloy.
    [0055] Parts made of calcinable material are proposed to be made of plastic, such as polypropylene.
    [0056] In the event that the bottom wall and the rest of the fixing base are independent elements, the through hole will pass through both elements.
    [0057] According to a further embodiment it is proposed that the thickness of the tubular wall portion provided with accordion pleated rings be equal to or less than 1 mm or preferably equal to or less than 0.5 mm. With these thicknesses it is possible to obtain the elastically deformable properties mentioned above in some of the calcinable materials commonly used for these applications.
    [0058] Preferably the thickness of the tubular wall portion where the frustoconical rings are defined will be equal to or greater than 0.05 mm. A smaller thickness may be insufficient as to confer elastic force to the material usually used for this application, then producing plastic deformations.
    [0059] Typically the calcinable material used will be a plastic material, preferably polypropylene.
    [0060] It is also proposed that the inner annular seat surface and the start of a first accordion pleated ring be coplanar or in parallel planes separated by less than 2 mm. This allows to ensure a very low center of rotation of the tubular joint, lower than that provided by other systems.
    [0061] The tubular wall portion provided with accordion pleated rings will preferably occupy at least one fifth of the length of the tubular wall.
    [0062] The possibility that the entire length of the tubular wall is provided with accordion pleated rings is also contemplated.
    [0063] According to a preferred embodiment, the minimum distance separating the outer and inner annular surfaces will be equal to or less than 2 mm.
    [0064] It will be understood that references to geometric position, such as parallel, perpendicular, tangent, etc. they admit deviations of up to ± 5 ° with respect to the theoretical position defined by said nomenclature.
    [0065] It will also be understood that any range of values offered may not be optimal in their extreme values and may require adaptations of the invention for said extreme values to be applicable, said adaptations being within the reach of one skilled in the art.
    [0066] Other features of the invention will appear in the following detailed description of embodiments.
    [0067] Brief description of the figures
    [0068] The foregoing and other advantages and features will be more fully understood from the following detailed description of an exemplary embodiment with reference to the accompanying drawings, which should be taken by way of illustration and not limitation, in which:
    [0069] Fig. 1 shows a side elevation and plan view of the proposed calcinable pillar, the straight calcined abutment being unfolded;

    [0071] Fig. 3 shows an exploded sectional view of the calcinable abutment, the dental implant or analogous dental implant and the fixation thyme according to an embodiment in which the entire fixation base is part of the same calcinable block with the rest of the abutment calcinable; Fig. 4 shows the same view as Fig. 3 but of an embodiment in which the fixing base is independent of the rest of the calcinable abutment, both elements being joined through a second pressure coupling configuration.
    [0072] Detailed description of embodiments
    [0073] The attached figures show exemplary non-limiting examples of the present invention.
    [0074]
    [0075] Figures 1, 2 and 3 correspond to a first embodiment of the proposed calcinable abutment 10.
    [0076]
    [0077] According to this embodiment, the calcinable abutment 10 consists of a fixing base 11 and a tubular wall 13 connected through a tubular joint 12, the whole assembly constituting a monobloc solidary body made of calcinable material.
    [0078]
    [0079] The tubular wall 13 has a hollow interior with an end adjacent to the fixing base 11 closed by a bottom wall which includes in its center a through hole 16 that crosses the bottom wall.
    [0080]
    [0081] The size of said through hole 16 will be smaller than the size of the hollow interior of the tubular wall 13, so it will involve a narrowing and define an inner annular seat 14 around it, on a face of the bottom wall accessible from the inside hollow of the tubular wall 13.
    [0082]
    [0083] The fixing base 11 will also include a first coupling configuration 15 accessible from the outside of the tubular wall 13, said first coupling configuration 15 being arranged around the through hole 16.
    [0084]
    [0085] In the example shown in Figs. 1, 2 and 3 the fixing base 11 has a flat annular inner seating surface 14 in the form of a disc around the through hole 16, and a first coupling configuration 15 in the form of a cylindrical hollow or in the form of a prismatic hollow, for example, with a square, hexagonal or octagonal base.
    [0086] In this example, the head of the dental implant 20 or the dental implant analog 20 will have a cylindrical or prismatic shape inserted in the recess defined by the first coupling configuration 15.
    [0087]
    [0088] On the contrary, in the example shown in Fig. 4, the fixation base 11 has a first protruding cylindrical or prismatic shaped coupling configuration, for example of a square, hexagonal or octagonal base, while it is the head of the dental implant 20 or of the dental implant analog 20 which has a cylindrical or prismatic hollow, for example with a square, hexagonal or octagonal base.
    [0089]
    [0090] A fixing screw 21 inserted through the hollow interior of the tubular wall 13 may be inserted through the through hole 16 and fixed to, for example, a dental implant analog 20, so that a head of said fixing screw will remain inside the hollow interior of the tubular wall 13, resting on the inner annular seating surface 14, pressing the first coupling configuration 15 of the fixing base 11 against the head of the dental implant analog 20. In this way a firm fixation of the calcinable abutment to the dental implant analog 20.
    [0091]
    [0092] In the example shown in Figs. 1, 2 and 3 the whole tubular wall assembly 13, with the respective tubular joint 12, as well as the fixing base 11, constitutes a monobloc solid of calcinable material, preferably plastic such as polypropylene.
    [0093]
    [0094] Alternatively, it is proposed that only the tubular body 13 with the tubular joint 12 constitute a monobloc solid of calcinable material, the fixing base 11 being an independent element and therefore can be of the same or another material. Therefore, the fixing base 11 may be made of calcinable material, or of non-calcinable material. In any case, the tubular body 13 will be attached to the fixing base 11. To achieve said joint it is proposed to include a second coupling configuration 17 to the fixing base 11, said second coupling configuration 17 being complementary to the lower end of the tubular body 13, achieving a tight connection between both bodies.
    [0095]
    [0096] In the example shown in Fig. 4, the fixing base 11 includes, as a second coupling configuration 17, an annular groove that is complementary with an annular shoulder defined in the base of the tubular body 13, allowing the insertion under pressure of said annular projection within the annular groove achieving retention of the tubular body 13 attached to the fixing base 11.
    [0097] It is proposed, for example, that the fixing base 11 be made of a metal so that when the superstructure is manufactured by replacing the calcinable material with molten metal, that part will not be calcined and will be integrated into the rest of the superstructure, thus ensuring greater dimensional accuracy. in the first coupling configuration 15.
    [0098]
    [0099] In any case, all embodiments propose that at least the portion of the tubular wall 13 adjacent to the fixing base 11 includes a tubular joint 12 which allows the orientation of the tubular wall 13 to be modified with respect to the fixing base 11.
    [0100]
    [0101] Said tubular joint 12 consists of a succession of pairs of truncated conical rings joined by their bases forming an accordion section capable of being collapsed or extended asymmetrically, allowing the tubular wall 13 to be oriented relative to the fixing base 11 and maintaining said orientation. .
    [0102]
    [0103] Each pair of rings consists of a first frustoconical ring and a second frustoconical ring both with an identical diameter at its base and at its cusp, but having a different height, therefore being non-symmetrical. Each first frustoconical ring is connected by its base to the base of a second frustoconical ring, defining in said union an annular hinge. The pairs of rings follow each other along the portion of the tubular body 13 that defines the tubular joint 12, the truncated cusp of each first frustoconical ring being attached to the truncated cusp of a second frustoconical ring through another annular hinge. The result of said succession of frustoconical rings is a succession of first and second alternate frustoconical rings that define an accordion section.
    [0104]
    [0105] The tubular joint 12 is proposed to be made of a defined material and thickness so that the frustoconical rings are elastically deformable, that is to say that they can be elastically deformed under an external force, but that they regain their original shape when said external force ceases.
    [0106]
    [0107] In this example the material is proposed to be a plastic material, for example polypropylene, and it is proposed that the walls of the first and second truncated cone rings have a thickness of between 1 mm and 0.05 mm, the preferred thickness being between 0 , 5 mm and 0.1 mm.
    [0108]
    [0109] Optionally, it is contemplated that not only a part, but that the entire length of the tubular wall 13 includes the aforementioned truncated conical rings, so that the tubular joint 12 covers the entire length of the tubular wall 13.
    [0110] It will be understood that the different parts constituting the invention described in one embodiment may be freely combined with the parts described in other different embodiments even if said combination has not been explicitly described, provided there is no harm in the combination.
