摘要/Abstract

摘要： 目的: 本病例报告一位骨性Ⅱ类高角下颌后缩患者,探讨隐形功能矫治器在下颌前导和咬合调整中的应用及效果。诊治经过: 患儿为9岁女性,主诉发现“下颌后缩”2 年余,诊断为错畸形（安氏Ⅱ类,骨性Ⅱ类,高角）。第一阶段使用隐形功能矫治器进行下颌前导,促进下颌骨前向生长;第二阶段采用标准隐形矫治器进行咬合调整。结果: 治疗后,患者下前牙位置及后牙垂直向高度得到有效控制,侧貌及咬合关系显著改善。结论: 隐形功能矫治器促进青少年骨性Ⅱ类高角后缩下颌前向生长,改善面部侧貌和咬合关系,具有独特优势。

Abstract: Objective: This case report presents a patient with skeletal ClassⅡ high-angle retrognathic mandible, exploring the application and effects of clear functional appliances in mandibular advancement and occlusal adjustment. Diagnosis and treatment: The patient was a 9-year-old female, complaining of “irregular teeth and protruding mouth” for several years, diagnosed with skeletal ClassⅡ. In the first phase, clear functional appliances were used for mandibular advancement to promote forward growth of the mandible. In the second phase, standard clear aligners were used for occlusal adjustment. Results: After treatment, the position of the lower anterior teeth and the vertical height of the posterior teeth were effectively controlled, with significant improvement in lateral profile and occlusal relationship. Conclusions: Invisible functional orthodontic appliances promote the forward growth of skeletal Class II high angle retrognathia in adolescents, improve facial profile and bite relationship, and have unique advantages.

Key words: early intervention, clear aligners, skeletal Class II, high-angle facial profile, mandibular retrognathia
