The bonded alumina crown. 1. The bonding of platinum to aluminous dental porcelain using tin oxide coatings.
A method has been evolved for bonding aluminous porcelain to pure platinum foil used for making porcelain crowns by the conventional 'tinner's joint' technique. It was found that good bonding was achieved when the platinum was coated with 0.2-2.0 mum of tin before firing on the porcelain. This paper describes experimental work for determining the optimum composition and thickness of the coating and the applicability of the technique to substrates other than platinum.
