摘要

A bonding material for joining a polymeric veneering material or porcelain ceramic to a metal framework of a dental restoration or dental prothesis before sintering the porcelain at a suitable temperature to form a clinically unbreakable structure. The bonding material is composed of finely divided metal particles including at least 50% gold or a gold alloy as its major constituent and finely divided particles of a carbonaceous material preferably of activated carbon.
