Abstract

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.

摘要

描述了一种使用氧化锡涂层将瓷附着于贵金属的新方法。铂箔与氧化铝瓷结合形成内层保护壳，从而减少微裂纹的形成并增加牙冠强度。通过使用厚层瓷可提高牙冠的透明度，并且该技术仍允许在关键的唇颈缘处采用瓷对接贴合。
