摘要
目的:介绍利用垂直曲控根辅弓在标准方丝弓矫治的牙列排齐整平阶段实现对牙齿转矩的有效控制。方法:选择18例安氏Ⅰ类中度或重度拥挤,具有明显异常冠转矩患牙的错[牙合]畸形病例。18例患者均在标准方丝弓矫治的第一阶段利用垂直曲控根辅弓对异常冠转矩患牙进行早期的转矩控制。治疗前留取记存模型,做常规模型测量分析。结果:治疗后,牙列建立中性咬合,目标患牙转矩控制良好。相比常规标准方丝弓矫治,矫治周期平均缩短2~3个月,跟踪随访2~5年,治疗效果稳定。结论:在标准方丝弓矫治的排齐整平阶段,针对具有异常冠转矩患牙的错[牙合]畸形,采用垂直曲控根辅弓,可以在一定程度上缩短矫治周期,后期保持效果稳定,托槽相关垂直曲控根辅弓为标准方丝弓矫治提供了新的思路。
Objective The purpose of this study is to introduce the effective control of tooth torque by the vertical curved root auxiliary arch in the standard alignment of the dentition Methods 18 cases of moderate or severe crowding in the Angle’s Class Ⅰwere selected with abnormal crown torque of teeth with malocclusion. In the first stage of standard square silk arch correction, the early torque control of abnormal crown torque was carried out by using the vertical curved root auxiliary arch in 18 patients. The memory model is retained before treatment, and the routine model measurement is analyzed. Results After treatment, the tooth column establishes the neutral occlusion, the target patient tooth torque control is good. Compared with conventional standard square silk arch correction, the correction period average shortened 2-3 months, followed up to 2-5 years, the therapeutic effect was stable. Conclusion In the standard square wire arch correction of the leveling stage, the use of vertical curved root auxiliary arch, aiming at abnormal crown torque teeth with malocclusion, can be a certain extent to shorten the orthodontic period, and maintain the stable effect in the later stage, and provide a new idea for the standard square wire arch correction with bracket-related vertical curved root auxiliary arch.
