摘　　要：目的:分别比较自体前牙及后牙移植于经种植手术器械处理人工牙槽窝和已有牙槽窝的临床疗效。方法:选取下颌前牙缺失26例,残根30例;下颌第一磨牙缺失32例,残根、残冠38例。使用超声骨刀去骨拔出自体埋伏牙、异位牙和下颌第三磨牙,植入使用口腔种植器械规范预备好的牙槽窝内;使用直丝弓托槽及个性化弓形圆钢丝固定4周。前牙2周行根管治疗,后牙植入前完成根管治疗。结果:前牙除人工牙槽窝分组1例因松动拔除外,其余随访2年,均稳固且功能正常;后牙除已有牙槽窝分组1例松动脱落外,其余随访2年,均稳固且功能正常。结论:自体前牙及后牙移植于已有牙槽窝和人工牙槽窝均能获得良好稳固性和咀嚼功能,但在远期效果方面,自体下颌前牙移植于已有牙槽窝优于人工牙槽窝;自体下颌后牙移植于人工牙槽窝优于已有牙槽窝。Objective：To evaluate the clinical effects of autologous anterior teeth and hosterior teeth transplantation to connatural and artifical alveolar socket.Methods：The research samples including two parts in each group：Anterior teeth group,26 cases with the anterior loss,and 30 cases with the residual roots or residual crowns;Posterior teeth group,32 cases with the posterior loss,and 38 cases with residual roots or residual crowns.Connatural tooth socket and artifical tooth socket were prepared with the dental implant appliance,the ambush teeth and 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 tooth in Anterior teeth group was extracted for loose in artifical alveolar socket,all other cases were followed-up in two years.The donor teeth were fixed and had normal chew function.Posterior teeth group：execpt one tooth was extracted for loose in connatural alveolar socket,all other cases were followed-up in two years,the donor teeth were fixed and had normal chew function.Conclusion：Autologous teeth transplantation to connatural and artifical alveolar socket are successful therapy.But the function of teeth being transplantation is different.Anterior teeth group,connatural alveolar socket part is better than artifical alveolar socket part;posterior teeth group,connatural alveolar socket part is less than artifical alveolar socket part.
