Abstract
A process for the production of a ceramic prosthesis by forming a blank from a mixture of zirconium oxide and hafnium oxide of between 94.8% and 95.3% by weight, yttrium oxide of between 4% and 5.2% by weight, and any further oxide as a balance of less than 1% by weight, with a monoclinic proportion of below 5% by volume. The blank is put into the shape of the required prosthesis by means of a rotating tool of metallically bound diamond grains, using specific operating parameters for the tool.
