Claim:
1. A method for manufacturing a dental prosthesis, the method comprising: receiving three dimensional data indicative of a patient's oral cavity; generating, based on the three dimensional data, a dentition model that includes 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 first portion of the dental prosthesis, the first portion being an internal part of the dental prosthesis and including an inner surface of the dental prosthesis, the three dimensional shape data of the first portion including a preparation coupling portion of the dental prosthesis that is configured for coupling the first portion of the dental prosthesis and the preparation, the prosthesis data further comprising three dimensional shape data of an outer surface of the first portion of the dental prosthesis; fabricating the first portion of the dental prosthesis based on the prosthesis data; and transmitting data for manufacture of a second portion of the dental prosthesis, the second portion being configured to couple with the first portion, the transmitted data including at least one of: 1) three dimensional shape data of the outer surface of the first portion, and 2) three dimensional shape data of an inner surface of the second portion that is configured for coupling the second portion and the first portion.
