Abstract:
1. A method for manufacturing a dental prosthesis, comprising: receiving a three dimensional data indicative of a patient's oral cavity; generating based on the three dimensional data a dentition model so as to identify a prosthesis preparation and external surface shape geometry of a prosthesis coupling portion of the preparation; generating, based on the dentition model, prosthesis data comprising three dimensional shape data of a preparation coupling portion of the prosthesis, wherein the preparation coupling portion is configured for coupling the prosthesis and the preparation; transmitting prosthesis data for manufacture of the prosthesis such that the coupling portion of the prosthesis and coupling portion of the preparation have a predetermined criteria comprising a fitting tolerance of about 40 microns or less, wherein manufacturing the prosthesis according to the predetermined criteria is shared among a service center and a dental lab.
