摘要
目的:评估自制GG纯钛烤瓷材料的生物安全性。方法:依据ISO标准,制作GG纯钛瓷粉材料试件,选用细胞毒性试验、急性毒性试验、口腔黏膜刺激试验,对该纯钛体瓷材料的毒性、黏膜刺激性进行生物安全性评估。结果:该体瓷材料细胞毒性评分为0级;急性毒性实验评价为无毒性;口腔黏膜刺激实验肉眼观察无红斑,显微镜评分≤4。结论:该自制纯钛体瓷材料具有良好的生物安全性。
AIM : To evaluate the biological security of GG titanium body porcelain. METHODS : Preliminary biocompatible tests of material were performed depending on the ISO7405 - 1997 (E) standard. The cytotoxicity test, acute systemic toxicity test, and oral mucous membrane irritation test were performed to test its security. RESULTS: The cytotoxicity test of the material was grade 0. The acute systemic toxicity test showed no toxicity. There was no irritation to the oral mucosa. CONCLUSION: The GG titanium body porcelain showed excellent biocompatibility on the preliminary tests.
