〔摘要〕 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。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特别是低角型深覆的矫治。

〔Abstracts〕Objective:To introduce a combined method for the treatment of anterior deep overbite.Methods: 62 cases with anterior deep overbite were treated with a modified appliance which was composed of four parts-the anterior bite plate,the anchorage on the second molars,the rectangular wire with higher elasticity and intermaxilla traction.Results: Satisfactory results were obtained in all the cases treated with this method in past two years,The period of treatment in leveling stage was about 4 month (in average).Conclusion: This combined method was conformed to the biomechanical mechanism in orthodontic treatment and is feasible for the treatment of anterior deep overbite cases with lower mandibular plane angle.
