Quizplus · Accepted Answer

A porcelain-fused-to-metal crown has a metal framework covered with a thin layer of porcelain on the outer surface, providing the aesthetic benefits of porcelain with the strength of metal. A porcelain jacket crown consists entirely of porcelain, while an onlay and three-quarter crown are partial coverage restorations that cover less of the tooth than a full crown.
