Abstract
The aim of the invention is to improve the bond between the oxide ceramic and the veneer material and to increase the durability of said bond. According to the invention, an adhesion promoter (mixture of silicate ceramic and quartz) is applied as a sol to a main body that is to be veneered and that has not yet been densely sintered, the main body being made of oxide ceramic or starting materials thereof. The main body is then sintered to a final state together with the worked-in adhesion promoter, and afterwards the veneer material is applied. The invention is used, for example, to produce dental crowns and bridges having a high load-bearing capacity.
