Abstract:
A process for the production of a dental prosthesis having at least a prosthetic cap intended to be fitted on an implantation zone of the human body and a prosthetic crown supported by the cap, wherein the process comprises:sensing the implantation zone with a sensor to obtain implantation zone measurement data used in producing a digitized three-dimensional representation (R1) of the implantation zone, defining a three-dimensional representation of an internal (R1c) surface of the prosthesis, corresponding to an internal surface of the cap on the basis of the digitized three-dimensional representation (R1) of the implantation zone, while taking account of rules connected with the insertion and sealing of the prosthesis, defining a digitized three-dimensional representation (R2) of an external surface of the prosthesis, on the basis of environmental parameters of the prosthesis, while taking account of the constraints from the internal surface (R1c) of the prosthesis, consisting of the internal surface of the cap, and defining a digitized three-dimensional representation (R3) of the external surface of the cap, on the basis of the external surface (R2) of the prosthesis, while taking into account of the internal surface (R1c) of the prosthesis, the criteria pertaining to mechanical durability, including thickness, and aesthetic criteria to form a three-dimensional digitized model of the prostic cap.
