ABSTRACT:
A method for making a jacket crown restoration is disclosed wherein the crown has a metal foil substrate of a high fusing temperature metal such as platinum as an integral component of the finished porcelain jacket crown. The present invention provides both anterior and posterior porcelain metal crown restorations and methods for making same. According to the present invention, a thin metal foil of a high fusing temperature metal is molded around a die of the tooth to be replaced. The foil has two ends which are terminated in a bondable mechanical joint to form a sealed thin metal foil substrate or skeleton for the dental preparation. The foil substrate is appropriately cleaned, coated with a retention compound to enhance the bonding of a veneer to the foil substrate and thereafter coated with a veneer to form the dental jacket crown.
