A method for generating a virtual model of a subperiosteal dental implant device. The method comprises: obtaining a virtual mouth model of a patient providing a three-dimensional representation of at least a section of a jaw bone of a patient, using a non-invasive modelling method; positioning at least one replacement tooth in relation to the section of the jaw bone defined by the virtual mouth model; positioning at least one implant head at a respective implant position; and designing and generating a virtual model of the subperiosteal dental implant device having a shape at least partially derived from a shape of the section of the jaw bone defined by the virtual mouth model and at least a portion of each one of the at least one implant head extending from the subperiosteal dental implant device at the respective implant position.

A positioning system is provided, comprising a support beam for attachment to an individual's jaw, and a removable denture comprising a bottom surface formed with a recess configured for receiving therein the support beam, the support beam and the recess being configured to preclude movement therebetween when the support beam is fully received within the recess. The support beam or the recess comprises one or more positioning grooves extending parallel to a path of insertion of the denture, and the other comprises one or more positioning protrusions laterally projecting therefrom and configured to be slidingly received within a corresponding positioning groove to provide at least a partially snug fit. The one or more positioning grooves and the corresponding one or more positioning protrusions are configured on one or more of a labial, lingual, or an face extending between the labial and lingual faces, of the recess and the support beam.

A dental prosthesis and a process for design and manufacturing, incorporating an overdenture and a dental implant framework that will be designed and manufactured simultaneously.

A system of components or implements for easily and precisely installing a dental implant, and a method of installing the dental implant, within a patient's jaw, is disclosed. The system comprises a rotary cutter guide and a rotary cutter. Orthogonal slots are defined within the rotary cutter guide so as to precisely position the rotary cutter within the rotary cutter guide as well as to permit the rotary cutter to form slots within a patient's jaw so as to accommodate winged members of a winged dental implant. A method of installation is also disclosed, and the system and method may be utilized in conjunction with the installation of both a single winged implant or a dual winged implant wherein the two winged implants are connected together by means of a connecting bar or plate.

A dental prosthetic assembly includes a semi-flexible reinforcement bar and a polymer and glass outer layer chemically luted to the semi-reinforcement bar outside of the reinforcement bar. The semi-flexible reinforcement bar forms an interior of the dental prosthetic assembly and at least a portion of the polymer and glass outer layer forms teeth of the dental prosthetic assembly. A coupling system of a dental prosthetic assembly includes pins disposed in openings extending into the dental prosthetic assembly and implant abutments configured to be coupled with a mouth of a patient. The implant anchors have horizontal holes configured to receive the pins. The pins secure the dental prosthetic assembly to the implant abutments by moving into the dental prosthetic assembly through the openings and into the holes of the implant abutments.

Method for the production of a prosthetic article including mounting at least two implants supporting the prosthetic article to be realized, in a model reproducing the user's gum, with the implants along the profile, heating a first implant to fuse an end of a first metallic wire to a first abutment corresponding to the portion emerging from the model of the first implant, heating the wire at a temperature lower than its melting temperature, in order to stretch it between the abutments, so that its development line is substantially parallel to the profile of the model at each point, heating the second implant in order to allow the fusion of the other end the first wire on the second abutment, so as to form a first bridge, and shaping with the technical material the first and the second abutment to form the artificial teeth of the prosthetic article.

A kit (1) for preparing a dental prosthesis, having a master model (2) manufactured by means of an additive technology using an arrangement of material in successive layers (3), such as 3D printing, and having a fixing screw (4) with an outer thread (4a) intended to removably fix a dental prosthesis element on the master model (2). The master model (2) has at least one reference surface intended to receive the dental prosthesis element bearing thereon, said reference surface being produced during the manufacture of the master model (2) by additive technology. The master model (2) has at least one threaded, cavity (6), of which the inner thread (6a), intended to receive said fixing screw (4) by screwing, is produced during the manufacture of the master model (2) by additive technology. The outer thread (4a) of the fixing screw (A) has a pitch (P) greater than or equal to 10 times the thickness (E) of the layers (3), and it has a thread height (H) greater than or equal to 5 times the thickness (E) of the layers (3).

A method for generating a virtual model of a subperiosteal dental implant device. The method comprises: obtaining a virtual mouth model of a patient providing a three-dimensional representation of at least a section of a jaw bone of a patient, using a non-invasive modelling method; positioning at least one replacement tooth in relation to the section of the jaw bone defined by the virtual mouth model; positioning at least one implant head at a respective implant position; and designing and generating a virtual model of the subperiosteal dental implant device having a shape at least partially derived from a shape of the section of the jaw bone defined by the virtual mouth model and at least a portion of each one of the at least one implant head extending from the subperiosteal dental implant device at the respective implant position.

A dental implant has a substantially cylindrical configuration and a pair of wing members projecting outwardly from diametrically opposite side wall portions of the implant. The wing members have a substantially right triangular configuration with one leg of each right triangle effectively connecting the wing member to the body of the implant, the other leg of the right triangle extending outwardly from the body of the implant at an orientation that is perpendicular to the longitudinal axis of the implant body, and the hypotenuse side of the right triangle being radiused so as to promote osseointegration. In addition, two winged implants may be connected together by means of a connecting bar or plate. In accordance with this dual implant, the wing members are only provided upon the laterally external side wall portions of each implant while the oppositely disposed internal portions of each implant are integrally connected to the intermediary connecting bar or plate. The undersurface of the connecting bar or plate is likewise radiused so as to promote osseointegration.

The present invention is to provide implants for an artificial tooth that does not require a period, for integration of implant bodies and a jawbone as in the background art, enables treatment even of a patient whose jawbone is small in bone amount or thickness, can reduce the treatment period and the number of times of treatment for many patients, and can lighten the mental and physical burden of a patient by minimizing the impact to the jawbone, and this invention is characterized by the following means, an artificial tooth, implant device with an arrangement where at least two implant bodies, each having a shaft portion, form a pair, a hook portion, hooked in a hook hole bored in a jawbone, is provided on the shaft portion of each implant body, the hook, portion is bent with respect to the shaft portion, and when the respective implant bodies are hooked onto the jawbone, tip portions of the hook portions are positioned so as to face each other inwardly, the arrangement being provided with a fixing means for fixing the implant bodies to each other.
