目的：介绍一种组合式矫治装置及其应用。方法：该矫治方法由前牙平导板、高弹性方弓丝、第二磨牙设计支抗、后牙颌间垂直牵引等组成。结果：经临床应用２年，共６２例，效果良好。平均疗程４个月。该矫治方法的优点包括：１，前牙平（斜）导板在压低前牙和升高后牙的同时，还起到了肌激动器的作用，促使下颌骨长度与高度的发育；２，第二磨牙加入支抗系统使矫治力趋于合理，有利于牙弓的整平；３，高弹性方丝有利于牙弓的排齐和整平，同时能较好控制牙齿的位置和倾斜度；４，后牙早期颌间垂直牵引有助于后牙按一定方向萌出，并建立理想咬合关系，减小前牙覆牙合。结论：该矫治方法符合正畸生物力学原理，其疗效好，疗程短，适合于非高角型前牙深覆牙合特别是低角型深覆牙合的矫治。
Objective: To introduce a combined orthodontic appliance and its application. Methods: The orthodontic method consists of anterior flat guide plate, high elastic square arch wire, the second molar design support, posterior intermaxillary vertical traction and so on. Results: The clinical application of 2 years, a total of 62 cases, the effect is good. The average course of treatment for 4 months. The advantages of the orthodontic method include: 1, the anterior flat (oblique) guide plate in the lower anterior teeth and raising the posterior teeth at the same time, also played the role of muscle exciters to promote the development of mandibular length and height; 2, the second 3, high elastic square wire is conducive to dental arch alignment and leveling, while better control of tooth position and tilt; 4 The vertical traction of the posterior intermaxillary intervertebral column helps to erupt the posterior teeth in a certain direction and establish the ideal occlusion relationship to reduce the occlusion of the anterior teeth. Conclusion: The orthodontic method is in accordance with orthodontic biomechanics and has good curative effect and short course of treatment. It is suitable for the treatment of non-high angle anterior teeth deep overbite, especially of low angle deep overbite.
