残根牙拔除位点保存的临床初步观察 　[摘要]目的 探讨位点保存术对牙槽骨量的影响。方法 选取2012年9月～2014年12月我院的12例残根牙拔除牙后预计做种植修复患者作为实验组，选取我院同期的12例残根牙拔除后做传统修复患者作为对照组。分别测量两组术后3个月和5个月牙槽骨垂直向和水平向的吸收水平。结果 实验组术后牙槽骨在垂直向和水平向的吸收水平显著低于对照组，差异有统计学意义（P0.05）。结论 采用位点保存术进行残牙根拔除术，能够降低牙槽骨的吸收量，且软组织也有所增加，可以为患者后续种植术提供较多的软、硬组织量。 本文采集自网络，本站发布的论文均是优质论文，供学习和研究使用，文中立场与本网站无关，版权和著作权归原作者所有，如有不愿意被转载的情况，请通知我们删除已转载的信息，如果需要分享，请保留本段说明。 　[关键词]拔牙窝；位点保存术；牙槽骨；种植牙 　　[中图分类号] R782.11 [文献标识码] A [文章编号] 1674-4721（2016）12（a）-0113-04 　　Preliminary clinical observation of site preservation in the removal of residual root tooth 　　WANG Wen-biao 　　Aviation General Hospital of China Medical University，Beijing 100012，China 　　[Abstract]Objective To explore the influence of site preservation on alveolar bone mass.Methods 12 cases of residual root teeth underwent implant restoration from September 2012 to December 2014 in our hospital were selected as the experimental group，12 cases of residual root teeth underwent traditional restoration in the same period in our hospital were selected as the control group.The absorption level of alveolar bone of the vertical direction and the horizontal direction were measured after opevation for 3 months and 5 months in the two groups.Results The absorption level of alveolar bone of the vertical direction and the horizontal direction in the experimental group was lower than that in the control group，with significant difference （P0.05）.Conclusion The application of site preservation in the removal of residual root teeth can reduce the absorption of alveolar bone，and the soft tissue has been increased，which can provide more soft and hard tissue mass for the patient′s follow-up implantation. 　　[Key words]Tooth extraction socket；Site preservation technique；Alveolar bone；Dental implant 　　在临床手术中，残根牙拔除后拔牙窝在愈合过程中牙槽骨会发生不同程度的吸收，这种不可逆的牙槽骨吸收，不仅会导致牙龈乳头区牙龈的减少，而且可导致拔牙区的牙槽骨高度和宽度降低[1-5]。随着人们生活水平的日益提高，种植牙术已经被越来越多的患者所认可，成为患者牙体缺失修复术的常见选择，但是受植区的牙槽骨条件是种植修复成功的关键[6-10]。 　　引导骨再生（guid
