The strength of dental ceramics

Abstract

Considerable changes have taken place in the range of ceramic materials available for dental use. Although the appearance of dental porcelain is good and biocompatibility excellent, its mechanical properties are somewhat limited. As a consequence, a number of distinct developments have taken place primarily to achieve greater strength; other goals having been to improve accuracy and simplification of production procedure. Progress has been made, but at the present time newer ceramics must still be regarded as complementary to established porcelains.
