80年代中期推出的光固化冠桥复合树脂在很大程度上可替代烤瓷。但由于需要制作铸造金属帽状冠,对金属冠表面还需作硅喷涂技术处理,技术难度较高,设备投资昂贵,因而推广使用受到限制。从1988年开始,我们利用引进的光固化冠桥树脂和光固化机(Dentacolor XS)制作树脂贴面锤造冠(桥),取得较满意的效果。其制作要点如下: The light-cured crown-bridge composite resin introduced in the mid 80's can replace porcelain to a large extent. However, due to the need to make cast metal cap crown, the surface of the metal crown need to be treated with silicon spraying technology, high technical difficulty, equipment investment is expensive, so the promotion of use is limited. Since 1988, we have made the crown veneer made of resin veneer by using the light-cured crown bridge resin and Dentacolor XS, and achieved satisfactory results. The production points are as follows:
