【摘要】目的 观察和评价活动翼矫治器治疗骨性垂直向不调内倾型深覆患者的效果。方法 选择恒牙期安氏Ⅱ2 类内倾型深覆患者20 例（女15 例，男5 例，平均年龄18.8 岁），均采用活动翼矫治器非拔牙治疗，矫治前后拍摄头颅侧位X 线片进行测量,并行配对t 检验,分析评价矫治效果。结果 应用活动翼矫治器治疗内倾型深覆牙合患者临床操作简单，矫治周期短，平均疗程11 个月。与治疗前相比，治疗后患者下颌平面角(FH-MP)增加（23.00°± 6.76° vs 21.59°±5.32°），覆减小[(1.02±0.81)mm vs (5.67±1.22)mm]，上下切牙唇向开展并压低，切牙突度和倾斜度增加，U1-NA 距增加[(4.67±1.21) mm vs (1.24±1.37)mm] ，U1-NA 角增加(24.40°±6.36° vs 11.70°±6.87°)，下切牙高度降低 [(37.16±1.81)mm vs (38.90±1.84)mm], L6-MP 升高[(31.68±2.87) mm vs (30.38±3.45)mm],差异均有统计学意义，磨牙关系由远中调为中性关系。结论 活动翼矫治器治疗骨性垂直向不调的安氏Ⅱ2 深覆患者，能够较快打开咬合，矫正切牙舌倾，具有矫治效果明显，操作简便，疗程短的优点，但对后牙的转矩控制可能不足。

Abstract:

[Abstract] Objective  To investigate and evaluate the change and efficacy of Active -wing Appliance in patients with lingual tipping deep overbite of Angle classⅡdivision 2 malocclusion．Methods  Twenty patients with lingual tipping deep overbite of Angle class Ⅱ division 2 malocclusions were selected for our study. Among the twenty patients, fifteen are girls and five are boys, whose age are from 16.0 to 23.0 years old with average of 18.8 years old . The patients were treated with Active -wing technique and all of them were non-extracted．Cephalometric films were taken before and after treatment to assess the effect of treatment . Eleven angular and thirteen linear measurements were taken. Paired t test was performed to analyze and evaluate the effects before and after treatment. Results  Active-wing Appliance have advantage of easy operating with short treatment cycle for treatment of deep overbite of Angle class Ⅱ division 2 malocclusion. It only takes 11 months in average for the treatment. After treatment, mandibular plane angle were increased (23.00°±6.76° vs 21.59°± 5.32°)，overbite were decreased [ (1.02±0.81) mm vs (5.67±1.22) mm] to reach normal level; incisors were labial incline sig? nificantly with increased protrusion and inclination; Post treatment parameter improvement also include: U1-NA distance in? creased (4.67±1.21 ) mm vs (1.24±1.37) mm; U1-NA angle increased (24.40°±6.36° vs 11.70°±6.87°); lower incisors were significantly intruded[ (37.16±1.81) mm vs（38.90±1.84）mm]; L6-MP were extruded [(31.68±2.87) mm vs (30.38±3.45) mm]; The cuspid and molar relationships were changed from Class Ⅱ to ClassⅠ occlusion. Conclusion  The Activewing Appliance can quickly open overbite and correct incisor lingual tipping for Angle class II division 2 with lingual tipping deep overbite. It is easy to operate and has been improved as efficient and shortened treatment. Meanwhile, it also saves arch wire. The Active-wing Appliance is especially powerful for lingual tipping deep overbite. However, the deficiency in torque control of premolars might be noticed.
