Class II division 1 malocclusion is the most common malocclusion seen in day-to-day practice. The majority of the patients with class II division 1 malocclusions have the presence of underlying skeletal discrepancy between maxilla and mandible. The treatment of skeletal class II division 1 depends upon the age of the patient, growth potential, severity of malocclusion, and compliance of patient with treatment. Myofunctional appliance can be successfully used to treat growing patients with class II division 1 malocclusion having retrusive mandible. This article presents a discussion on treatment of class II division 1 due to mandibular deficiency with growth modification approach using myofunctional appliances and a series of three case reports of treatment of skeletal class II division 1 malocclusion using myofunctional appliance followed by fixed mechanotherapy.
安氏II类1分类错牙合是日常临床实践中最常见的错牙合类型。大多数安氏II类1分类错牙合患者存在上颌骨与下颌骨之间潜在的骨骼差异。安氏II类1分类骨骼畸形的治疗取决于患者的年龄、生长潜力、错牙合的严重程度以及患者对治疗的依从性。肌功能矫治器可成功用于治疗下颌后缩的安氏II类1分类生长发育期患者。本文讨论了使用肌功能矫治器采用生长改良方法治疗下颌骨发育不足导致的安氏II类1分类错牙合，并报告了3例使用肌功能矫治器治疗安氏II类1分类骨骼畸形错牙合，随后进行固定机械治疗的病例。
