Abstract

The invention relates to a process for the preparation of dentures, comprising the steps:

a) preparation of a blank, b) processing of the blank by milling methods, c) dense sintering of the blank in a temperature range from 1200 to 1650°C, the blank comprising a pre-sintered material and having a raw breaking resistance of 15 to 30 MPa.
