ABSTRACT:
An improvement is provided in the so-called "Foil" system for producing jacketed porcelain dental crowns. One of the most significant improvements is the formation of a crush-resistant coping comprised of a die-conforming noble metal foil and a bonded sintered alloy. Extremely strong crowns are produced in a short order of time by applying the porcelain over such a coping.
