摘　　要：目的　对TM种植体的最佳表面特征进行研究。方法　选用 3种不同表面特征的TM种植体 ,建立山羊下颌骨种植模型。通过骨—种植体硬组织切片 ,观察了骨—种植体界面。结果　粗化处理有利于骨整合的发生 ,低结晶度的生物活性陶瓷涂层更有利于骨整合 ,且便于倒楔形间隙的骨形成。Objective To study the optimal surface properties of the TM implant.Methods 3 types of different surface properties of the TM implant were selected. An implant model with the mandibule of goats was built. The osseo-implant interface by hard tissue slices with both the TM implant and bone were observed.Results Rough treatment was benefit to improve the osseointegration,lower crystallization bioactive coating was more advantageous to achieve the osseointegration and aided to bone development in the reverse-tapered gap. Conclusions It is the best to choose the TM implant surface property with lower crystallization bioactive coating.
