Method of making a dental restoration from a frame and a veneer

A method of making a dental restoration from a frame and a veneer, the frame and the veneer having inner and outer surfaces, wherein the inner frame surface corresponds to an inner surface of the dental restoration, and the outer veneer surface corresponds to an outer surface of the dental restoration, with the inner veneer surface and the outer frame surface being adapted to be mated with one another to form the dental restoration, the method implemented with a computer system with one or more processors and memories, the method comprising the steps of:

• (a) providing an outer veneer surface in the form of surface data;
• (b) determining, by the one or more processors, an outer frame surface in the form of surface data, based on the outer veneer surface;
• (c) determining, by the one or more processors, an inner veneer surface in the form of surface data, based on the outer frame surface;
• and
• (d) providing an inner frame surface in the form of surface data, based on a natural tooth surface prepared to receive the dental restoration.
