Clinical application of orthodontic traction for maxillary labial inversionand ambushment of central incisors
正畸牵引上颌唇侧翻转埋伏中切牙的临床应用研究

摘要

目的 分析正畸牵引上颌唇侧翻转埋伏中切牙的临床应用。方法 选择我院2012年1月-2022年1月上颌唇侧翻转埋伏中切牙患者共50例，给予正畸牵引治疗，研究上颌中切牙翻转埋伏阻生正畸治疗的临床效果。在固定矫治初期，每15~20天复查一次，复查时使用50-70 g的矫治力矩。结果 50例病人中40例“成功”，占80.00%；其中7名患者为“一般”，占14.00%；其中3例患者“失败”，占6.00%。结论 正畸牵引上颌唇侧翻转埋伏中切牙的临床应用中，通过有效的正畸牵引矫治，上颌埋伏翻转阻生中切牙能进入相应位置，避免拔除，效果良好。

Abstract

Objective To analyze the clinical application of orthodontic traction for maxillary labial lateral inversion and ambush of central incisors.
Methods A total of 50 patients with maxillary labial flip impacted central incisor in our hospital from January 2012 to January 2022 were selected and treated with orthodontic traction. The clinical effect of maxillary flip impacted central incisor impacted orthodontic treatment was studied. In the initial period of fixed correction, the patients were reexamined every 15 to 20 days with a correction torque of 50 to 70 g.
Results 40 out of 50 patients were successful, accounting for 80.00%. Among them, 7 patients were "general", accounting for 14.00%; Among them, 3 patients "failed", accounting for 6.00%.
Conclusion   In the clinical application of orthodontic traction maxillary labial inverted impacted central incisors, the effective orthodontic traction treatment can get the maxillary inverted impacted central incisors into the corresponding position and avoid extraction, with good effect.
