摘要 [目的]对两种表面形态不同的钛种植体在不同种植时期骨结合界面情况进行组织学研究。[方法]采用同体对照的方法,将酸蚀面螺纹状种植体和机械面螺纹状种植体各32颗分别植入16只雄性杂种狗的双侧胫骨中,在植入后4周、8周、12周、16周对种植体骨界面进行组织学观察,计算接触长度分数比(CLF)。[结果]在植入后4周、8周、12周,酸蚀面螺纹状种植体的CLF分别为26.4%、62.8%、75.3%,机械面螺纹状种植体的的CLF分别为17.3%、50.7%、56.5%,差异有统计学意义(P<0.05);在植入后16周,两者的CLF分别为87.1%、84.3%,差异无统计学意义(P>0.05)。[结论]在植入早期,酸蚀面螺纹状种植体表面骨结合优于机械面螺纹状种植体。随植入时间的延长,两者均形成良好的骨性结合界面。
