Abstract
Class II malocclusion is one of the most frequent problems encountered in orthodontic. The most common characteristic of Class II malocclusion is mandibular retrognathia rather than maxillary protrusion according to McNamara. Non-growing patients with Class II mandibular retrusion are mostly treated with fixed functional appliances. This article represents two case reports of Class II division 2 malocclusion cases treated with Forsus Fatigue Resistant Appliance after initial levelling and alignment. Forsus Fatigue Resistant appliance in particular when used in conjunction with full bonded fixed appliance facilitate the correction of Class II Div 2 malocclusion by skeletal and dental changes.
II 类错牙合畸形是正畸中最常见的问题之一。麦克纳马拉认为，II类错牙合畸形最常见的特征是下颌后缩，而不是上颌前突。下颌后缩II类的非生长期患者大多采用固定功能矫治器进行治疗。本文报告了两例 II 类 2 级错颌畸形病例，在经过初步矫治和对齐后，使用 Forsus 抗疲劳矫治器进行了治疗。Forsus 抗疲劳矫治器与全粘结固定矫治器一起使用时，尤其有助于通过骨骼和牙齿的改变来矫正 II 类 2 分区错颌畸形。
