PRODUCTION OF DENTAL PROSTHESES FROM A THREE-DIMENSIONALLY MAPPED AND DIGITIZED POSITIVE MODEL

摘要

The invention relates to a method for the production of replacement teeth (5)from a three-dimensionally determined and digitised model, whereby forimproved handling, cost and quality of the thus produced replacement tooth (5)a method comprising the following steps is disclosed: inputting the data forthe digitised model, treating the inner surface (9) of the surface model witha given offset value to generate a cement gap (7, 8) between the toothreplacement (5) to be and tooth stump (1, 2) and calculation of a programmefor machining the blank or a mould by means of a machine tool.
