Abstract
A dental prosthesis and a process for design and manufacturing, incorporating a dental implant framework and veneering overlay that will be designed and manufactured simultaneously and permanently fixated to one another.
Claims33
A dental prosthesis for restoring the appearance and function of a patient's missing teeth comprising a veneering overlay, a dental implant framework and a series of implants and abutments adapted to be placed within a patient's mouth, wherein the dental implant framework is intended to mate to the series of implants and abutments where the design of the veneering overlay and dental implant framework are based upon digital data obtained from the patient:
- the dental implant framework further comprising a plurality of fittings to mate with the corresponding implants and abutments in the patient's mouth;
- the dental implant framework further comprising a macro retention feature to provide resistance to lateral forces;
- the dental implant framework further comprising a plurality of bridging structures to attach the fittings to one another;
- the veneering overlay further comprising a plurality of tooth contours and gingiva contours
- the design of the veneering overlay and dental implant framework being determined from the digital data defining the appropriate tooth contours, gingiva contours and implant/abutment locations for the dental prosthesis;
- the veneering overlay further comprises a veneering overlay mating surface and a dental implant framework structure, wherein the dental implant framework structure comprises a dental implant framework mating surface and the veneering overlay mating surface and the dental implant framework mating surface further create a predefined mating surface and a clearance gap to allow for an appropriate mating of the veneering overlay to the dental implant framework;
- the veneering overlay mating surface is created on the basis of a unique subtract body that is dependent upon design features of the dental implant framework mating surface;
- the plurality of tooth contours and gingiva contours of the veneering overlay being derived from the digital data from the patient;
- the veneering overlay and dental implant framework being permanently fixated to one another.
A dental implant framework intended to mate with a veneering overlay and a plurality of implants and abutments comprising:
- a plurality of fittings to mate with and correspond with plurality of implants and abutments in the patient's mouth;
- a macro retention feature providing resistance to lateral forces;
- a plurality of bridging structures attaching the plurality of fittings to one another;
- wherein the design of the dental implant framework is determined from digital data obtained from the patient defining the appropriate tooth contours, gingiva contours and plurality of implant and abutment locations for a dental prosthesis;
- wherein the combination of the plurality of bridging structure, macro retention feature, and plurality of fittings providing the complete embodiment of the dental implant framework;
- wherein the dental implant framework structure includes a predefined mating surface and clearance gap to allow for an appropriate mating of a veneering overlay to the framework;
- where the mating surface of the veneering overlay is created on the basis of a unique subtract body that is dependent upon design features of the designed framework;
- where the dental implant framework is constructed from available dental material;
- and
- where the veneering overlay and dental implant framework are permanently fixated to one another.
