Patient J.S., adult, female, presented with a morphologic skeletal asymmetry of the mandible resulting in a unilateral posterior crossbite, and a Class III skeletal discrepancy characterized by a hyperdivergent facial pattern (FMA, 30 degrees), retrognathic maxilla (SNA, 79 degrees), and compensating maxillary alveolar dental protrusion (1-NA, 7 mm). Maxillofacial surgery was declined. Orthodontic treatment, utilizing the Tweed-Merrifield edgewise technique, widened the maxillary dentition with a combination buccal crown torque and buccal root torque and with lingual crown torque in the mandibular posterior quadrant. Temporomandibular joint symptoms lessened and function improved with orthodontic treatment. The skeletal asymmetry improved and the patient was happy with the result, including her profile and her beautiful smile.
患者J.S.，成年女性，表现为下颌骨形态性骨骼不对称，导致单侧后牙反合，以及III类骨骼不调，其特征为面型高度散开（FMA，30度）、上颌后缩（SNA，79度）和上颌牙槽骨代偿性牙前突（1-NA，7毫米）。患者拒绝接受颌面外科手术。采用Tweed-Merrifield方丝弓技术进行正畸治疗，通过颊侧冠转矩和颊侧根转矩相结合以及下颌后牙区舌侧冠转矩来扩宽上颌牙列。正畸治疗后颞下颌关节症状减轻，功能改善。骨骼不对称情况得到改善，患者对结果满意，包括她的侧面轮廓和美丽笑容。
