In 1995, We compared and discussed the properties of two types of implants bodies, after set crown. These two types of implant body were,1-Diopside Implant2-Titanium Implant.The Diopside Implant showed a better property of osseo-integration after 8 weeks, and at this time we setted crown. The Diopside Implant body was observed for four weeks after setted the crown.Findings :1-The Diopside implant formed new bone around its body, specially new bone selectively integrated at diopside granule, The bone marrow was lightly narrow by new bone.2-The Titanium Implant formed a little new bone and less Osseo-integration. Spaces between the Titanium Implant and the bone was observed.Conclusions :1-Both types of implant showed the ability of new bone formation under functional forces.2-The bone remodeling and new bone formation was faster in the Diopside Implant in relation to the bone remodeling and formation the Titanium Implant Side.3-No findings of collapse, drop out and melting were observed in the Diopside granule. Diopside Implant showed be superior than Titanium Implant under functional and non functional forces.

1995年，我们对两种种植体在固定冠后的性能进行了比较和讨论。两种种植体类型分别为1-透辉石种植体2-纯钛种植体，透辉石种植体在种植8周后表现出较好的骨结合性能，此时我们进行冠修复。结果：1、透辉石种植体周围有新骨形成，特别是在透辉石颗粒处有选择性的新骨结合，骨髓轻度狭窄; 2、纯钛种植体周围有少量新骨形成，骨结合较少。结论：1-两种种植体在功能性载荷作用下均表现出新骨形成的能力; 2-透辉石种植体的骨重建和新骨形成速度快于种植体侧; 3-透辉石颗粒未出现塌陷、脱落和熔化现象。在功能和非功能力下，透辉石植入物表现出比钛植入物更上级。
