Abstract

A method for the production of replacement teeth (5) from a three-dimensionally determined and digitized model, whereby for improved handling, cost and quality of the produced replacement tooth (5) a method including the following steps is carried out: inputting the data for the digitized model, treating the inner surface (9) of the surface model with a given offset value to generate a cement gap (7, 8) between the tooth replacement (5) to be made and tooth stump (1, 2) and calculation of a program for machining the blank or a mold by means of a machine tool.
