摘　　要：追踪随访了12例植入成形的微孔性生物活性玻璃陶瓷(BGC)修复下颌骨节段性缺损的病员,时间为1至2年。采用放射性核素骨显像法结合常规手段,对其植入区的骨代谢进行了初步研究。结果表明,植入区内存在着骨质代谢。当受植区骨膜完整,单纯植入 BGC,植入区内的骨代谢在术后3月即可达到高峰。当受植区骨膜不完整、自体松质骨及 BGC 联合植入,植入区内的骨代谢在术后1年达到高峰。The 12 patients,whose mandible were reconstructed with porous bioactive glassceramic(BGC),were followed up in one or two years postoperatively.The bonymetabolism of the implanted region was monitored using radio-isotope scanning,clinicaland radiological techniques.The results showed that there was bony metabolism in theimplanted region.When the periosteum of the implanted region was intact and onlyBGC was implanted,the bony metabolism could reach the peak at 3rd month posto-peratively.When the periosteum of the implanted region was damaged,autogenouscancellous bone and BGC were implanted to gether,the bony metabolism could reachthe peak at 1st year postoperatively.
