引导骨再生(GBR)可以实现骨组织的垂直再生,无论是使用不可吸收膜还是Ti-mesh的可吸收膜,但到目前为止,还没有研究发表比较这两种手术的组织学和组织形态学结果。

引导骨再生(GBR)可以实现骨组织的垂直再生,无论是使用不可吸收膜还是Ti-mesh的可吸收膜,但到目前为止,还没有研究发表比较这两种手术的组织学和组织形态学结果。

 

纳入40名部分缺牙患者需要在后下颌骨放置垂直骨再生种植体:20名患者随机分配到A组(Ti-PTFE);而20名患者分配到B组(胶原蛋白加Ti-mesh)。两组患者的移植材料均为50:50的自体骨和骨异体混合材料。9个月后,从增生部位(再生骨ROI-1;原生骨ROI-2)取组织活检,进行组织学和组织形态学分析。测量骨组织(B.Ar)、生物材料(Mat.Ar)和软组织(St.Ar)的百分比,也计算出周边的测量值。ROI-1值也与两组的ROI-2进行比较。

 

结果,研究共收集了25个样本,并连续进行分析。A组13个,B组12个。A组的平均B.Ar、Mat.Ar和St.Ar分别为39.7%、8.6%和52.1%;B组的结果类似,平均值分别为42.1%、9.6%和48.3%,无显著统计学差异。两组ROI-1和ROI-2之间均有差异。最后,ROI-1和ROI-2的骨结构指数均有统计学差异。

 

总之,本研究的初步结果表明,使用不可吸收膜的GBR和使用可吸收膜的Ti-mesh与自体骨和骨异体结合的GBR具有相似的组织学和组织形态学结果。
