【摘要】 目的 比较自体牙移植于固有牙槽窝和人工牙槽窝的临床效果。方法 选取下颌第一磨牙残根、残冠24例，下颌第一磨牙缺失22例，用种植机修整固有牙槽窝或制备人工牙槽窝，拔出自体第三磨牙，植入预备好的牙槽窝内。夹板固定复合树脂粘结4周，根尖已形成者术后2周行根管治疗。结果 除人工牙槽窝组1例因松动拔除外，其余随访3年，均稳固，咀嚼功能正常。X-线片示移植牙与牙槽骨紧密贴合，固有牙槽窝组牙周膜及牙根完整性优于人工牙槽窝组。结论 自体牙移植于固有牙槽窝和人工牙槽窝均能获得很好的稳固性和咀嚼功能，但在牙周膜形成及保持牙根完整性方面移植于固有牙槽窝优于人工牙槽窝。

【Abstract】 Objective To evaluate the clinical effects of autologous teeth transplantationto connatural and artifical alveolar socket.Methods The research samples including two parts： 24 cases with the first molar residual roots or residual crowns,and 22 cases with the first molar loss, connatural tooth socket and artifical tooth socket were prepared with the dental implant appliance, the third molar was extracted and transplanted to the alveolar sockets which had been prepared. Arch bar fix transplantation teeth with composit resin for 4 weeks, pulp therapy for mature tooth after operation 2 weeks.Results Execpt one teeth was extracted for mobile in artifical alveolar socket part. All the other cases were followed-up in three years, the donor teeth were fixedness and had normal chaw function.X-ray showed：transplantation teeth was adhere to alveolar,the periodenral membrane and teeth root were better in connatural alveolar socket part than that in artifical alveolar socket part.Conclusion Autologous teeth transplantationto connatural and artifical alveolar socket are successful therapy,but the periodenral membrane and teeth root are better in connatural alveolar socket part than that in artifical alveolar socket part.

自体牙移植术是指将患者自体口内的阻生牙、埋伏牙、错位牙拔出后易位移植于其他缺失牙部位。临床上多采用将正在萌出、牙根尚未发育完成的下颌第三磨牙移植于因龋坏而丧失的下颌第一磨牙部位，以代替第一磨牙行使功能。 临床上常遇到残根、残冠但牙槽窝完好者及牙齿缺失无固有牙槽窝者，两种不同情况移植的临床效果如何。作者于2006年~2008年之间，随机选取46例不同患者行下颌第三磨牙移植于下颌第一磨牙部位。移植牙获得了很好的稳固性和咀嚼功能，二者的区别在于牙周膜的形成及牙根完整性的保持。现报告如下。
1 一般资料
固有牙槽窝组：残根、残冠患者24例，24颗牙齿，男11例，女13例，年龄16~42岁，平均25岁。符合下列条件：欲拔除的下颌第一磨牙牙根与牙槽骨无粘连，无牙周炎，无根周炎，牙槽骨无吸收。第三磨牙牙冠近远中宽度≤缺牙间隙近远中宽度。18例牙根已完全形成，6例牙根未完全形成。人工牙槽窝组：缺失牙患者22例，缺失22颗牙齿，男13例 ......
