A technique for repairing the anterior region with use of aluminous porcelain-bonded-to-platinum-foil has been described. This technique produces a strong replacement and maintains the esthetic appearance of the original prosthesis.
A new method of attaching porcelain to precious metals using tin oxide coatings is described. Platinum foil is bonded to aluminous porcelain and forms an inner protective skin, thereby reducing the formation of microcracks and increasing the strength of the crown. An improvement in translucency of the crown is obtained by using thick layers of porcelain, and the technique still allows the use of a porcelain butt fit at the critical labiocervical margin.
