Skeletal class III malocclusion with severe skeletal disharmonies and arch discrepancies is usually treated via the conventional orthodontic-surgical approach. However, when associated with tooth impaction and periodontal risks, the treatment is more challenging and complex. The esthetic, occlusal, and periodontal stability of the treatment outcome is more difficult to obtain. The 16-year-old female patient in this case was diagnosed with dental and skeletal Class III malocclusion, bilateral impacted maxillary canines, and scalloped thin gingiva. The multidisciplinary management included a segmental arch technique, extracting two premolars, a subepithelial connective tissue graft surgery, and orthognathic surgery. The esthetic facial profile, pleasant smile, appropriate occlusion, and functional treatment results were obtained and maintained in 8-year follow-up.
骨性 III 类错颌畸形伴严重骨骼不协调和牙弓差异,通常采用传统的正畸-正颌联合治疗。然而,当伴有牙齿阻生和牙周风险时,治疗更具挑战性和复杂性。治疗结果的美观、咬合和牙周稳定性更难获得。本病例中的 16 岁女性患者被诊断为牙性和骨性 III 类错颌畸形、双侧上颌尖牙埋伏阻生、牙龈退缩呈扇贝状。多学科管理包括片段弓技术、拔除两颗前磨牙、上皮下结缔组织移植术和正颌手术。在 8 年的随访中,获得并维持了美观的面型、满意的笑容、合适的咬合和功能治疗效果。
