Metal ceramic unique items for dentistry

In this paper the possibilities to create metal ceramic unique items in dentistry using titanium as framework material are shown. A special investment material as well as a special casting unit are necessary to produce precise frameworks of the biocompatible material titanium, because of its very unique chemical and physical properties. The resulting requirements and the desire for a simple, user-friendly, and safe dental processing are very demanding of the investment material regarding flow behaviour, speed of the setting and sintering process as well as reactions with titanium. These conditions can be obtained by using refractory oxides in the investment material.
