摘　　要：目的探讨正畸方丝弓托槽+圆丝片段在牙外伤处理中的临床应用。方法选择牙外伤致牙体松动、脱位的患者65例(共计128颗患牙),随机分为三组,分别采用不锈钢丝结扎、牙弓夹板和方丝弓托槽+圆丝片段固定。于1、3、6、12个月复诊,观察疗效。结果三种固定技术均取得了一定的效果,但方丝弓托槽+圆丝技术的成功率与其他两组相比均有明显的差异。结论方丝弓托槽+圆丝技术在牙外伤处理中疗效显著且牙周及基牙损伤较小。Objective To evaluate the clinical curative effect of segmental edgewise bracket ＋ round wire appliance in the treatment of dental trauma. Methods One hundred and twenty-eight loose or dislocation teeth of sixty-five patients were randomly divided into three groups. The first group was treated with steel wire fixation while the second group was treated with dental splint technique. The third group （the experimental group） was treated with segmental edgewise bracket ＋ round wire. Clinical effects of the three groups were assessed and recoded after 1, 3, 6 and 12 months. Results All the techniques applied in our study proved to be effective in loose teeth fixation. Significant differences were observed in clinical effect between groups. Conclusion Segmental edgewise bracket ＋ round wire shows more positive effect in the fixation of traumatic teeth compared with the other two techniques. In addition, it causes less injuries to the abutment teeth.
