[Investigations into ways of improving the ultimate strength of ceramic dental materials (author's transl)]. 1979

A Breustedt, and S Horn

Despite major improvements, ceramic dental materials, as albite glasses, still show unsatisfactory strength properties. It has been found that the combination of Keradens type dentinal compounds with aluminum-oxide-containing core materials, because of internal stresses, results in a higher ultimate strength than is suggested by the strength values of the single components. In addition, it has been found that wetting the surface of the ceramic test specimen results in a significant decrease in ultimate strength.

D003776	Dental Porcelain	A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water.
