A 23-year-old Mongolian woman came for a consultation with chief complaints of protrusive lips and a gummy smile. The clinical examination showed a convex profile, a protrusive maxilla, excessively proclined and extruded maxillary incisors, and a Class II Division 1 malocclusion. Temporary anchorage devices (TADs) in the posterior dental region were used as anchorage for the retraction and intrusion of her maxillary anterior teeth. Those appliances, combined with a compensatory curved maxillary archwire, eliminated the severe gummy smile and the protrusive profile, and corrected the molar relationship from Class II to Class I. With no extra temporary anchorage devices in the anterior region for intrusion, the treatment was workable and simple. The patient received a satisfactory occlusion and an attractive smile.
一位 23 岁的蒙古族女性前来就诊,主要抱怨嘴唇突出和露龈笑。临床检查显示凸面型,上颌前突,上颌切牙过度前倾和外倾,安氏 II 类 1 分类错颌。在后牙区使用临时支抗装置(TAD)作为上颌前牙内收和压低的支抗。这些矫治器与补偿性的上颌弓丝曲共同消除了严重的露龈笑和前突面型,将磨牙关系从 II 类纠正为 I 类。由于在前牙区没有额外的用于内收的临时支抗装置,治疗是可行且简单的。患者获得了满意的咬合和美观的笑容。
