骨性Ⅱ类错畸形是一种常见的青少年儿童错畸形类型,若得不到及时的矫正,可能引起口腔肌肉功能异常、口腔颌面发育畸形,影响患者身心健康。本文报道1例生长发育高峰期混合牙列期的9岁男性患儿,患骨性Ⅱ类错畸形伴开唇露齿和下颌后缩,通过13个月的头帽式肌激动器治疗,成功纠正了骨性Ⅱ类错畸形,随访1年,疗效稳定,面部生长型良好。

Skeletal class Ⅱ malocclusion is a common disease in adolescents and children. It can cause oral and muscular dysfunction, oral and maxillofacial development deformity, and even affect the physical and mental health of patients if it could not be corrected in time. This case report presented the early intervention of a 9-year-old boy who was in the early mixed dentition and had a severe protruding upper incisor and retrognathic mandible, as well as skeletal class Ⅱ malocclusions. After the 13-month treatment with headgear-activator, the malocclusion had been corrected, and both the front look and facial profile met the aesthetic criteria.
