目的：：本研究通过动物实验观察并探讨种植术中环形骨缺损周围剩余骨壁厚度对术后骨愈合的影响。方法：选取8只健康小型猪,雌雄各半,随机分为两组,每组4只。按实验设计,左侧为实验组,用裂钻磨除各面制备环形骨缺损,使四周骨壁厚度分别为0.5、1、1.5 mm,植入种植体,距离四周骨壁2mm,覆盖胶原膜,软组织复位缝合。右侧设空白对照,直接缝合。术后8、12wk 分别处死4只动物,制取标本,进行骨密度测量及种植体骨磨片观察。结果：骨密度测量结果显示,不同时间点实验组与对照组的骨密度差异有统计学意义(P <0.05)。骨磨片观察,骨缺损区周围剩余骨壁厚度越厚成骨效果越好。结论：种植体周围环形骨缺损剩余骨壁越厚其骨缺损修复效果越好。

Objective:To observe and investigate the effect of the thickness of the bone wall around the central bone defect on the healing of bone after surgery.Methods:8 healthy pigs were randomly divided into two groups,half male and half female,(n = 4 ).Designed by experiment using.split drill grinding and removing the surface preparation of annular bone defect,the thickness of the wall of the surrounding bone were 0.5,1,1.5 mm.Distance of implant around the bone wall was 2mm,covered with collagen membrane,soft tissue suturing reattachment.On the left side of the experimental group,the right side of the blank control. After 8,12 weeks the pigs were killed for animal specimens and bone density was measured and observed of implant bone slices.Results:Bone density measurements revealed that BMD had statistical significanct differences at different time points (P <0.05)in the experimental group and control group.Observeing the bone slices,the bone defect around the residual bone wall was thicker,the bone healing was better.Conclusion:The effect of bone defect repair is better in the bone defect of the bone around the implant that have thicker bone wall.
