摘要
目的:观察铜-锌合金和金-钯合金在Branemark种植义齿的应用效果.方法:分别用铜-锌合金和金-钯合金制作种植义齿金属支架,用树脂或烤瓷完成义齿,观察戴入1年后的变化.结果:铜-锌合金制作的义齿支架被腐蚀率为100%,并有人工牙齿树脂脱落和支架断裂现象,有菌斑;金-钯合金制作的义齿支架无被腐蚀现象,无菌斑.结论:金-钯合金是制作Branemark种植义齿支架的理想金属.
Objective: To observe the application of Cu-Zn and Au-Pd alloy as framework of Branemark implants. Methods: Observe the changes of Cu-Zn and Au-Pd alloy framework one year after the application of using resin or porcelain as artificial teeth materials respectively. Results: The corrosive rate of Cu-Zn alloy framework was 100%. And dislocation of resin artificial teeth, fracture of the framework and adhesion of plaque were observed. Neither corrosion nor adhesion of plaque was observed in Au-Pd framework. Conclusions: The Au-Pd alloy is an ideal kind of metal for Branemark implant framework.
