| 摘 要： | 目的：研究纯钛种植体和非血管化髂骨块的骨结合情况。方法：10只杂种犬被随机分成5组，分别切取两侧游离髂骨移植于对侧，移植骨内同时植入钛种植体，术后不同时间点取材，组织学观察。结果：3周时，移植骨以吸收和坏死为主，6周时有新骨形成，9周时新骨形成的数量增加，12周时移植的骨块成活，骨组织改建完成，植入的钛种植体和移植的髂骨块之间无软组织介入，标志种植体与移植骨之间骨结合完成。结论：在本实验条件下，钛种植体和非血管化髂骨块可以形成完全骨结合。

| Abstract: | Objective:To investigate the osseointegration process of titanium implant and non-vascularized iliac bone grafts.Methods:10 mongrel were divided into 5 group randomly.Bone grafts were resected from iliac crest and then transplant to the opposite side. Animals were killed in different time after surgery, histological observation were done.Results:After 3 weeks postoperatively, bone grafts dissolved, resorbed or necrosis partly;After 6 weeks, new bone began to regenerated, new bone formed.After 9 weeks, the amount of new bone increased; After 12 weeks, bone interface around implant formed,without soft tissue interrupt.Conclusions:Osseointegration can formed between non-vascularized iliac bone grafts and titanium implant. |
