The bonded alumina crown. 2. Construction using the twin foil technique.
A technique has been developed for making aluminous procelain crowns bonded to thin tin oxide coatings on platinum foil. These crowns require only very thin metal linings of less than 0.05 mm, thus reducing metal costs and considerably improving aesthetics. In addition, by using the "twin foil" technique, porcelain butt fits may be obtained without loss of fit.
