The success of early orthopedic treatment in patients with Class III anomalies depends on facial skeletal development and type of treatment. This case report describes the treatment of a 12.6-year-old girl who had a severe Class III malocclusion with a 6-mm anterior crossbite, a deep overbite, a narrow maxilla, and unerupted maxillary canines. The treatment plan included rapid palatal expansion to expand the maxilla, reverse headgear to correct the maxillary retrognathia, a removable anterior inclined bite plane to correct the anterior crossbite and the deep overbite, and fixed edgewise appliances to align the teeth. One canine was brought into alignment, but the other was placed in occlusion in its transposed position. Ideal overjet and overbite relationships were established, and the final esthetic result was pleasing.
早期正畸治疗在Ⅲ类错颌畸形患者中的成功取决于面部骨骼发育和治疗类型。本病例报告描述了一名12.6岁女孩的治疗情况，该女孩患有严重的Ⅲ类错颌畸形，伴有6毫米的前牙反颌、深覆颌、上颌狭窄以及上颌尖牙未萌出。治疗计划包括快速腭中缝扩展以扩宽上颌、使用头帽颏兜矫治器纠正上颌后缩、使用可摘式前斜导平面矫治器纠正前牙反颌和深覆颌，以及使用固定直丝弓矫治器排齐牙齿。一颗尖牙排齐，但另一颗尖牙在异位萌出的位置上建立了咬合关系。建立了理想的覆盖和覆颌关系，最终的美学效果令人满意。
