摘　　要：钛种植体在口腔中腐蚀现象已被学者研究发现并引起重视。骨内是否存在纯钛种植体缝隙腐蚀？本文对此进行了动物实验研究。扫描电镜结果友现：金属腐蚀发生与存在介质环境密切相关；在骨介质环境中2、4、6、8、12周五个时间段内纯钛种植体在骨内未发现明显覆盖螺丝的缝隙腐蚀。Titanium implant corosion have been found and followed with interest,About the problem of crevice corrosion oftitanium implant in endosseous,the authors has studied the cover screw of implant in endosseous with SEM and found that the corrosion correlated with the surroundings;At2、4、6、8、12weeks,there were no crevice corrosion of cover screw of implant in endosseous.
