The bonded porcelain margin in porcelain-fused-to-metal prosthetics

Progress in dentistry is often made when existing techniques and products are combined with new developments. For example, although porcelain has been used for decades and Buonocore reported on its use in 1955, only in early 1980 did bonded porcelain become popular. Today, we assume that porcelain facings and inlays are an integral part of dentistry.
