[Abstract]Objective To research the clinical efficacy of different fixation methods on the loose teeth traumatic，find an effective method. Methods Select Ⅱ~Ⅲ degree of traumatic teeth loose 165 patients with 243 bad teeth, patients were randomly divided into 3 groups, each of the 55 patients with 81 teeth, A metal wire ligation group, B group with steel wire-enamelsticky legal, C group Edgewise brackets with fixation, record the injuries, fixed, clinical efficacy of treatment for 3 months and periodontal inspection. Results Steel wire-enamel sticky legal efficacy is superior to the group and the ligation wire Edgewise bracket with fixation group, the difference was statistically significant（P<0.05）, the gingivitis, periodontal pocket formation, alveolar bone resorption change is significantly（P<0.01）. Conclusion Steel wire-enamel sticky legal treatment of traumatic tooth mobility significant clinical efficacy, it is worth to clinical practice.
牙外傷是指牙齒受到急劇創(chuàng )傷，特別是打擊或撞擊所引起的牙體、牙髓和牙周組織的損傷。頜面外傷經(jīng)常伴發(fā)或原發(fā)牙外傷，患者大多數表現為牙齒的松動(dòng)、脫位或者移位，外傷性牙松動(dòng)的主要治療原則是盡量保存自體牙，及時(shí)將患牙清理、復位、固定，復位后的固定是影響治療成功與否的重要因素。臨床常用的固定方法有金屬絲結扎法、鋼絲-釉質(zhì)黏合法、方絲弓托槽固定法等。本文對部分臨床外傷松動(dòng)牙采用方絲弓正畸法固定，并與傳統的金屬絲結扎法、牙弓夾板固定法療效進(jìn)行比較，旨在探索一種固位強、效果好、不損傷牙周的松牙固定方法。
