Abstract
A method of making a dental restoration is provided. The dental restoration comprises a frame and a veneer. An inner veneer surface and an outer frame surface are adapted to be mated with one another to form the dental restoration. The method in particular comprises steps of (a) providing an outer veneer surface; (b) determining an outer frame surface, based on the outer veneer surface; (c) determining an inner veneer surface, based on the outer frame surface; and (d) providing an inner frame surface, based on a natural tooth surface. The method may be advantageous for rapid, precise and inexpensive manufacturing of a dental restoration.
