高熔钴铬合金已广泛应用于固定义齿和可摘义齿修复,尤其用于铸造可摘义齿支架,解决了很多义齿设计中的难题,大大提高了义齿的质量。而各种义齿铸件表面光洁度的好坏,直接影响义齿的美观和质量。人工打磨抛光大铸件既费时又费力,效果往往不佳。因此,铸件多采用电化学抛光处理,但按常规的电化学 High-cobalt-chromium alloy has been widely used in fixed denture and removable denture repair, especially for casting removable denture bracket, to solve many problems in the design of dentures, greatly improving the quality of the denture. The quality of various dentures castings surface finish, a direct impact on the aesthetic appearance and quality of dentures. It is both time-consuming and labor-intensive to polish large castings manually, often with poor results. Therefore, the casting is more used electrochemical polishing, but according to conventional electrochemical
