受区骨膜对非血管化骨移植种植体与骨结合强度的实验研究

目的：探讨受区骨膜对非血管化骨移植种植体与骨结合强度的作用，为临床在非血管化骨移植同期进行种植体植入提供依据。方法：在狗的双侧下颌骨下缘制备非血管化骨移植模型，将钛芯羟基磷灰石涂层(Ti—HA)圆柱形种植体植入移植骨块中，左侧去除骨膜为实验组，右侧为对照组。分别于术后2个月、4个月、6个月处死动物取材，进行大体观察和抗拉力测试。结果：在各个时间点上，实验组和对照组的骨愈合情况及植入种植体与骨结合强度无明显差异。结论：骨膜的存在与否对非血管化骨移植种植体与骨结合强度无明显影响。

Experimental Study of Recipient Periosteum to Planting Body of Non-vascularized Bone Graft and Bone Integrated Intension

Objective: To discuss the effect of recipient periosteum to planting body of non-vascularized bone graft and bone integrated intenison and to furnish fresh evidence for clinical practice on grafting body at the same term of non-vascularized bone graft. Methods: After non-vascularized bone graft models on the interior margin of double mandibula of dogs were prepared, two Ti-HA columniform planting bodies were planted into double grafting bones. The left removed periosteum was the test group, the right was the control group. Tissues on the executed animals after two monthes, four monthes and six minthes of the surgery were obtained and general observation and pull-resisting test were done. Results: On each time spot, there is no obvious difference between the test group and the control one on the healing status of bone and the concrescence strength of planting body and bone. Conclusions: The existing of periosteum has no obvious effect on planting body of non-vascularized bone graft and bone integrated intension.
