上颌埋伏尖牙外科正畸联合治疗的疗效分析

The efficacy analysis of maxillary canine surgical orthodontic treatment

目的 观察上颌埋伏尖牙外科正畸联合治疗的临床疗效.方法 选取46例上颌埋伏尖牙患者并随机分为两组,23例患者采用非手术助萌治疗作为对照组,23例患者采用外科正畸联合治疗作为试验组,在两组患者治疗1年内连续进行CT检查,观察疗效.结果 23例试验组患者在开拓间隙、助萌术后3~10个月,平均（6.1±2.0）个月时埋伏牙矫治至正常位置,其中1例发生龈缘萎缩,2例牙周附着不足.15例对照组患者在开拓间隙后6个月内埋伏尖牙自行萌出矫治至正常位置,无一例发生相关并发症,试验组埋伏尖牙萌出率高于对照组,差异有统计学意义（P＜0.05）.结论 上颌埋伏尖牙外科正畸联合治疗,可快速有效的矫治上颌埋伏阻生尖牙,效果显著.

Objective To observe the clinical efficacy of the maxillary dental surgical orthodontic treatment. Methods Forty - six maxillary impacted teeth patients were randomly divided into two groups, 23 patients with non - surgical eruption treatment as the control group, 23 patients with surgical orthodontic treatment as experimental group, and continuous CT examination was performed in the two groups of patients within one year, then the efficacy was observed. Results Impacted tooth eruption was observed in its normal position in 23 cases after 3 - 10 month,including 1 case of shrinkage of the gingival margin and 2 cases of periodontal attachment inadequacy. For control pa- tients, impacted tooth eruption was found in its normal position by itself in 15 within 6 months after surgery, and there was no case of related complications. The impacted tooth eruption rate of the experimental group was higher than that of the control, and the difference was statisti- cally significant. Conclusion The maxillary dental surgical orthodontic treatment can quickly and effectively treat maxillary impacted ca- nines, and the effect is marked.
