摘　　要：目的:观察埋伏阻生牙正畸治疗的临床疗效,探讨埋伏阻生牙有效的治疗方法。方法:选取2012年8月-2014年12月本院收治的18例单侧埋伏阻生牙患者,均根据患者埋伏阻生牙的具体情况制定正畸治疗方案,分别进行手术暴露、正畸排齐、正畸牵引。于治疗后对治疗牙和对侧同名牙进行牙周检查和测量,拍摄全口根尖片,记录牙周探诊深度和牙槽骨水平,并进行比较。结果:18例18颗埋伏阻生牙中,行助萌术治疗7颗(38.89%),环切术治疗2颗(11.11%),翻瓣导萌术9颗(50.00%);18颗埋伏阻生牙治疗成功16例(88.89%),有效2例(11.11%);与对侧同名牙比较,治疗牙牙周探诊深度、牙槽骨水平比较,差异均无统计学意义(P>0.05);治疗后,共4例患者出现伤口感染,发生率为22.22%。结论:正畸治疗埋伏阻生牙具有较好的治疗效果,可建立良好的龈缘形态,减少牙周损害。Objective： To observe the effect of orthodontic treatment for impacted teeth, discuss the effective treatment for impacted teeth. Method： 18 patients with impacted teeth in our hospital from August 2012 to December 2014, all the patients underwent surgical exposure, orthodontic aligning, orthodontic traction according to Concrete conditions of the impacted teeth. After orthodontic treatment, the probing depth, bone level was detected and compared between the impacted teeth and contralateral teeth. Result： Among the 18 impacted teeth, 7 teeth （ 38.89% ） were treated by closed approach, 2 teeth （ 11.11% ） were treated by circular excision, and 9 teeth （ 50.00% ） were treated by flap guided eruption. Among the 18 impacted teeth, 16 impacted teeth were treated successfully, the successful rate was 88.89%, and 2 impacted teeth were treated effectively, the effective rate was 88.89%. Compared with the contralateral teeth,, there was no statistically significant difference on the probing depth, bone level of impacted teeth （ P〉0.05 ） . After orthodontic treatment, 4 patients occurred wound infection, and the rate of wound infection was 22.22%. Conclusion： Orthodontic treatment for impacted teeth has better therapeutic effect, can establish a good gingival margin morphology, which can reduce periodontal damage.
