摘要
目的探索生物可吸收性引导组织再生膜(BGTRM)对种植体周骨组织形成的作用。方法8只犬一侧种植体顶部覆盖BGTRM膜,另一侧为未放BGTRM膜的对照组,于4周、3月、6月处死动物,以X线、组织学和计算机测量手段观察和比较两组种植体周骨质形成的情况。结果四周时,BGTRM组种植体周骨质的量和密度明显高于对照组,六月时,两组骨质形成已无明显差异。结论BGTRM具有促进种植周骨质形成的功能。
Objective To study the effect of a bioresorbable guided tissue regeneration membrane (BGTRM ) on boneformation of periimplant. Methods Eight beagles were implanted immediately after extraction of bilateral bicuspids, thefirst and the second molar. Implants of one side were covered with BGTRM and the other side without BGTRM was ascontrol. The beagles were sacrificed at 4 weeks and 3 - 6 momths respectively after operation, the bone formation was observed by x - rays and histolgy. Results The density and quantity of bone of periimplants in BGTRM group were muchgreater than those in the control four weeks after operation, After 3 months, the bone formation in mesial buccal region wasstill more significant in BFTRM group , Nidifference was observed between the two groups six months postoperation. Conclusion BGTRM has the potential to improve the bone formation of periimpla-nts.
