正畸患者中常见到各种类型的牙不对称,可分为骨型、牙型、肌型或混合型。骨型不对称最好用正畸一外科联合治疗,牙型或轻度骨型不对称多用正畸治疗。本文讨论了正畸治疗4种不对称畸形的生物力学及常用方法设计。 1.(牙合)平面倾斜的治疗:①前段(牙合)平面倾斜;上下(牙合)平面同时倾斜,可对远离(牙合)平面的上下前牙进行垂直牵引。但多数患者前段(牙合)平面倾斜只在上或下牙弓。例 Orthodontic patients often seen in various types of tooth asymmetry, can be divided into bone type, tooth type, muscle type or mixed type. Bone asymmetry is best to use orthopedic surgical joint treatment, dental or mild skeletal asymmetric multi-use orthodontic treatment. This article discusses the biomechanics of orthodontic treatment of four asymmetric deformities and the design of common methods. 1. (Occlusal) plane tilt treatment: ① anterior (occlusal) plane tilt; upper and lower (occlusal) plane at the same time tilt, can be away from the (occlusal) plane vertical traction of the upper and lower anterior teeth. However, most patients with anterior (occlusal) plane tilt only in the upper or lower arch. example
