Non-surgical treatment of Class II subdivision may involve complex mechanics or asymmetric tooth extraction in its resolution. This report demonstrates the result and the short-term stability of Class II subdivision treated with asymmetrically installed Herbst appliance followed by conventional fixed orthodontic appliance. The approach allowed the correction of the unilateral Class II molar relationship and increased overjet, as well as the deviation of dental midlines, with improvement in lip posture and facial profile. The results remained stable two years after treatment, confirming the treatment success.
骨性 II 类错[牙合]的非手术治疗可能涉及复杂的力学机制或不对称拔牙来解决。本报告展示了采用非对称安装的Herbst 矫治器治疗骨性 II 类错[牙合]后，再使用传统固定矫正器的短期稳定性和治疗结果。该方法不仅纠正了单侧 II 类磨牙关系，还增加了覆[牙合]，并改善了中线偏斜，同时唇形和侧貌也得到了改善。治疗两年后，结果仍然稳定，证实了治疗的成功。
