摘　　要：目的对比后牙区自体牙移植后3种不同固定方法的临床效果,为临床自体牙移植固定方法的选择提供参考。方法选取10例后牙区自体牙移植为研究样本,分为3组,分别采用正畸弓丝法、树脂钢丝固定法和牙弓夹板固定法进行固定。对比3组固定后牙周状况、移植牙稳定性、1年内牙根吸收等情况。结果 3种固定方法均可对移植牙起到固定作用,1个月拆除固定装置后,10例移植牙均未脱落。但使用树脂钢丝固定法时,固定装置易脱落。牙弓夹板固定时,牙周卫生维护较困难。正畸弓丝法,操作较复杂且成本较高。结论 3种固定方法均可取得良好的固定效果,短期内在牙周膜形成和牙根吸收等方面无明显差别。Objective To compare the clinical effect of three different fixation methods for autogenous posterior tooth transplantation. Methods Ten cases of autogenous tooth transplantation were divided into three groups. Three different fixation methods were applied,orthodontic arch wire,resin plus wire and dental splint. The periodontal status,stability of the translanted teeth and root absorption were examined after one year. Results All the three fixation methods could fix the translanted teeth. After removal of the fixation device for one month,there was no detachment in the 10 cases. The fixture was easy to fall off in the resin plus wire method. The maintenance of periodontal health was more difficult in the splint fixation method. The operation was more complicated and costly in the orthodontic arch wire method. Conclusion All the three fixation methods studied can achieve good fixation effect.
