This case report presents the camouflage treatment that successfully improved the facial profile of a patient with a skeletal Class III malocclusion using bone-borne rapid maxillary expansion and mandibular anterior subapical osteotomy. The patient was an 18-year-old woman with chief complaints of crooked teeth and a protruded jaw. Camouflage treatment was chosen because she rejected orthognathic surgery under general anesthesia. A hybrid type of bone-borne rapid maxillary expander with palatal mini-implants was used to correct the transverse discrepancy, and a mandibular anterior subapical osteotomy was conducted to achieve proper overjet with normal incisal inclination and to improve her lip and chin profile. As a result, a Class I occlusion with a favorable inclination of the anterior teeth and a good esthetic profile was achieved with no adverse effects. Therefore, the hybrid type of bone-borne rapid maxillary expander and a mandibular anterior subapical osteotomy can be considered effective camouflage treatment of a skeletal Class III malocclusion, providing improved inclination of the dentition and lip profile.
本病例报告介绍了一种掩饰性治疗方法，该方法通过骨支持式快速上颌扩弓和下颌前部根尖下截骨术，成功改善了一名骨性III类错牙合患者的面部轮廓。患者为一名18岁女性，主要诉求为牙齿不齐和下颌前突。由于患者拒绝全身麻醉下的正颌手术，因此选择了掩饰性治疗。使用带有腭部微型种植体的混合型骨支持式快速上颌扩弓器来纠正横向差异，并进行下颌前部根尖下截骨术，以获得正常切牙倾斜度的合适覆盖，并改善她的唇部和颏部轮廓。结果，实现了I类咬合，前牙倾斜度良好，美学轮廓佳，且无不良反应。因此，混合型骨支持式快速上颌扩弓器和下颌前部根尖下截骨术可被认为是治疗骨性III类错牙合的有效掩饰性治疗方法，可改善牙列倾斜度和唇部轮廓。
