With the development of prosthonditics, a new technique which combines PFM technique and casting framework of RPD appears and has being applied by more and more dentists. So we developed a new type of Co-Cr dental alloy which has good metal-porcelain matching and could be cast for RPD framework. The fomer research showed that it [...]
