摘要
目的：本文对应用国产膨体ｅ－ｐＴＦＥ膜引导牙周组织再生的动物实验的观察进行评价。方法：通过４只狗的１０颗牙（实验组）的牙周缺损行国产ｅ－ｐＴＦＥ膜覆盖引导牙周组织再生、７颗牙（对照组）的牙周缺损无ｅ－ｐＴＦＥ膜覆盖引导牙周组织再生，在３个月后行牙周组织学观察。结果：实验组新生牙槽骨新生牙周膜组织及新生牙骨质的修复再生的效果明显好于对照组（Ｐ＜０．０５），形成了的牙周结构，只是引导再生的牙周组织未完全恢复到正常的牙周组织高度。
Objective:The aim of this study was to evaluate the efficiency of domestic expanded polvtetrafluoroethylene (e PTFE) membrane on periodontal guided tissue regeneration (GTR). Methods:The periodontal defects of 10 dog teeth treated with e PTFE were investigated for three monthes, and compared with the contrals (7teeth). Results:The periodontal guided tissue regeneration in the treated group were significant higher than those in the control group ( P <0.05), but they did not recovered to the clinical attachment level at the end of third month. Conclusion:Our study indicatis that e PTFE membranes seem to be possible to produce the GTR in the replacement of periodontal defects.
