摘要
目的:通过将不同粗糙度的纯钛种植体植入软组织中,观察软组织对种植体的反应,评价各种种植体的组织相容性。方法:分别将光滑表面、机械表面、微粗糙表面(Ⅰ)、微粗糙表面(Ⅱ)、大粗糙表面的纯钛种植体在第1,30,60,83天分别植入家兔的背部肌肉中,在第90天切取包绕种植体的软组织,进行组织定量评价。结果:90天时微粗糙表面的种植体的软组织反应最小。结论:微粗糙表面能显著降低种植体-组织界面的炎症反应程度,减少软组织包绕层的厚度。
Objective： To investigate the tissue compatibility of commercial pure titanium implant with different roughness.Methods：We inserted the five kinds of implant into the back of rabbits at 1,30,60.83 days separately.and cut down the soft tissues around the implants at 90 days.Result：Qualitative and quantitative histological analysis discovered that commercial pure titanium implants with different surface roughness all have good biocompatibility,Special microrouphness.Conclusion： The microrough surface of implant could drop the inflammative reaction at the interface between implant with soft tissue ,reduce the thick of connective tissue around the implant.
