For a girl, aged 12 years 3 months, with a skeletal Class III malocclusion, negative overjet, severe maxillary crowding, and hyperdivergent pattern, orthognathic surgery combined with orthodontic treatment is often the treatment of choice, because it can greatly improve the patient's facial profile and ensure the long-term stability of the results. However, because of high risks and treatment expenses, patients sometimes refuse to have surgery. We report a nonsurgical combination therapy including facemask and multiloop edgewise archwires and the outcome for a patient with a developing skeletal Class III malocclusion and a long anterior facial height. Treatment included advancement of the maxilla by orthopedic means and counterclockwise rotation of the mandibular occlusal plane by the orthodontic dentoalveolar compensation of distal en-masse movement of the mandibular dentition.
对于一名 12 岁 3 个月的女性患者,存在骨骼 III 类错颌畸形、负覆颌、严重上颌拥挤和高角型,正颌手术联合正畸治疗通常是首选治疗方法,因为它可以极大地改善患者的面型,确保治疗效果的长期稳定。然而,由于手术风险高和治疗费用高,患者有时会拒绝手术。我们报告了一种非手术联合治疗方法,包括使用面具和多圈方丝弓,治疗一名骨骼 III 类错颌畸形和前面部高度较长的患者。治疗包括通过矫形手段对上颌骨进行前导,通过下颌牙列远中整体移动的正畸牙代偿来使下颌咬合平面逆时针旋转。
