摘　　要：采用细胞毒性实验 ,溶血实验及口腔粘膜刺激试验对 Ti- Zr合金的生物安全性进行了初步的评价。结果显示 :Ti- Zr合金细胞毒性实验评级为 0级 ,溶血程度为 0 .15 % ,口腔粘膜刺激试验未见异常组织学反应。由以上结果可以初步认为 Ti-In this study, the general toxicity tests including cytotoxicity, haemolysis and oral mucous irratation of the Ti-Zr alloy were investigated. The results showed the level of cytotoxicity was grade 0, the haemolysis degree was 0.15% and no histomorphologic change was observed in the animals of Ti-Zr alloy groups. These data indicate that Ti-Zr alloy has good biocompatibility as a dental material.
