钛合金ＴＣ４（Ｔｉ－６Ａｌ－４Ｖ）作根管－骨内种植术种植体，临床观察５３个月、超低碳不锈钢００Ｃｒ１８Ｎｉ１３Ｍｏ３作同样种植体临床观察６个月，经扫描电镜、Ｘ射线能谱仪观察分析，其表面均有轻微金属元素贫化现象，值得注意的是该区又皆有来自机体Ｃａ、Ｐ等元素附着或嵌入，加强了松牙固定效果。以同样方法在狗、猴牙种植１７和１４个月后，种植体检测结果与上述临床资料相同；组织学检查证明，两种材料均有良好的组织相容性。
Titanium alloy TC4 (Ti-6Al-4V) was used as a root canal-osseous implants. The clinical observation was 53 months. The ultra-low carbon stainless steel 00Cr18Ni13Mo3 was used as the same implant for 6 months. The scanning electron microscopy, X-ray energy dispersive spectroscopy Observations and analysis, the surface of the metal elements have a slight depletion of the phenomenon, it is noteworthy that the area and all from the body Ca, P and other elements attached or embedded, to strengthen the effect of fixed teeth. In the same way, after 17 and 14 months of implantation in dogs and monkeys, the results of the implant tests were the same as the above clinical data; histological examination showed that both materials had good histocompatibility.
