Abstract

The invention relates to a method for the production of replacement teeth (5) from a three-dimensionally determined and digitised model, whereby for improved handling, cost and quality of the thus produced replacement tooth (5) a method comprising the following steps is disclosed: inputting the data for the digitised 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 and tooth stump (1, 2) and calculation of a programme for machining the blank or a mould by means of a machine tool.
