摘要：

背景：引导骨再生对于成骨的引导及成形效果在基础研究及动物实验中已得到充分肯定，但国内有关人的颌骨骨缺损后引导骨再生中新生骨的组织学观察是一个空白。
目的：应用组织学检查了解人引导骨再生修复颌骨骨缺损的成骨效果。
方法：选取引导骨再生治疗颌骨骨缺损患者19例24个部位，于治疗后6个月行种植术中，中空钻取出术区新生骨，组织学观察，评价成骨效果。
结果与结论：所取新生骨可见不同发育阶段的骨形成。近根尖段骨中主要为板层骨，而冠方新生骨主要为纤维性骨形成，内含类骨组织及软骨性骨，极少板层骨。提示人颌骨骨缺损经引导骨再生后6个月成骨效果肯定，但远期效果还有待进一步观察。

Abstract:

BACKGROUND: Osteogenesis effects of guided bone regeneration have been verified in basic research and animal experiments. However, histological observation of bone regeneration following repair of human mandibular bone defects using guided bone regeneration is not reported in China.
OBJECTIVE: To study the osteogenesis effects of guided bone regeneration on the repair of human mandibular bone defects through histological observation.
METHODS: Twenty-four defects from 19 mandibular bone defect patients were subjected to guided bone regeneration therapy. After 6 months, dental implantation was performed. New bone tissues in the surgical area were taken using a hollow drill for histological observation and osteogenesis evaluation.
RESULTS AND CONCLUSION: Different developmental stages of bone formation were visible in new bone tissues. Lamellar bone tissues were mainly found near the root apex, while fibrous bone tissues containing osteoid tissue and cartilage bone formed at the dental crown. It indicated that there is a certain 6-month osteogenesis effect of guided bone regeneration, but the long-term effect needs further observation.
