Description:
The metal ceramic restoration first became available commercially during the later 1950s. This
is composed of a metal coping, which fits over the tooth preparation and ceramic that is fused to the coping. This is more resistance to fracture than the first all ceramic restoration [porcelain jacket crown], because the combination of ceramic and metal bonded together is stronger than the ceramic alone.
Historically, this was fabricated with metal margins, and the veneer was limited to visible areas. With
technological advances, the use of porcelain on occlusal and lingual surfaces has become common.
Several techniques have been developed to obtain porcelain margins on the labial aspect of the
restoration. A metal collar may be used in posterior areas in which esthetic appearance is a lesser issue, whereas the latter technique is common for teeth in the esthetic zone. Today this restoration is considered a routine procedure with excellent clinical performance
