珊瑚人工骨具有良好的生物相容性，生物降解性和骨传导性；单纯植入机体后有一定的体积丧失。本文将珊瑚骨和自体骨髓复合，修复兔下颌骨实验性骨缺损，术后不同时间行ｘ线检查，￣９９ｍＴｃ－ＭＤＰ骨显像和组织学检查；结果发现：术后２周植骨区开始有新骨形成，１２周骨缺损被修复，无体积丧失。实验结果表明，复合珊瑚骨移植，可加速骨缺损的修复，是一种良好的骨代用品。 Coral artificial bone has good biocompatibility, biodegradability and osteoconductivity; simply implanted into the body after a certain loss of volume. In this paper, the coral bone and autologous bone marrow complex repair of experimental rabbit mandibular defect, postoperative x-ray examination at different times, ~ 99mTc-MDP bone imaging and histological examination; results found: 2 weeks after the start of bone graft area With new bone formation, 12-week bone defects were repaired without volume loss. Experimental results show that the composite coral bone graft can accelerate the repair of bone defects, is a good bone substitute.
