摘　　要：目的:评价种植位点牙槽骨内的牙残片对种植修复的影响。方法:随机选择延期牙种植患者400例,对种植术中发现有牙残片的病例进行统计分析。结果:发现牙残片17例,其中磨牙最多,龋病为最常见拔牙原因。多数X线片明确存在牙残片影像,多数病例需要植骨,已完成修复的病例无失败。自然愈合或应用某些材料的拔牙创都可以正常愈合,但牙残片类似于某些对拔牙创愈合有不良影响的材料,可造成炎性反应。结论:牙残片对拔牙创愈合和种植修复过程有不良影响,但对最终修复成功率的影响尚不明确。Objective： To investigate the influence of tooth remains on dental implant therapy. Methods： Among 400 patients that received at least one implant, the patients who had tooth remains in the extraction socket were selected. Then we evaluated the number of case, the tooth site, the reason of extraction and GBR. Results： 17 cases were discovered tooth remains in the 400 patients. Most teeth were molars and caries was the first reason of extraction. Most tooth remains could be seen on radiographs. 10 patients needed GBR in the operation, and more cases had low bone density. There was no failed case among the patients who had final restoration. Usually the extraction sockets with or without materials could filling heal uneventfully, but there had signs of retarded wound healing with tooth remains in the sockets. Conclusion： Tooth remains do harm to the healing of extraction sockets and the course of dental implant therapy.
