Patent ID: 7110844

Claim:
A method for the fabrication of a dental prosthesis of at least one tooth to be fitted over a tooth preparation, comprising: a) providing a three-dimensional (3D) digital data relating to the patient's dentition, said 3D data including data representative of the surface topology of said preparation and its surroundings; b) generating a three-dimensional (3D) virtual model of a dental prosthesis for said at least one tooth based on said 3D data, the virtual model having an outer surface and an inner surface for fitting over a portion of the surface of the tooth preparation in close engagement; c) generating a computerized numerical control (CNC) set of instructions corresponding to the 3D model of said prosthesis; d) based on said set of instructions, fabricating a wax model of said prosthesis by a computerized numerical control (CNC) milling machine by milling an outer surface of said wax model corresponding to said outer surface of said virtual model and by milling an inner surface of said wax model corresponding to said inner surface of said virtual model; and e) fabricating a dental prosthesis from the wax model.
