This case report describes the treatment of a 25-year-old woman with a Class II malocclusion, secondary to mandibular skeletal deficiency, and mild overclosure. Inferior surgical repositioning of the maxilla is often the treatment of choice for patients with maxillary vertical deficiency; however, this patient had borderline vertical deficiency that was treated with a mandibular "tripod" advancement (leveling of the mandibular arch after surgery) coupled with a setback and down-grafting genioplasty. The surgical-orthodontic treatment plan, combined with cosmetic dentistry, resulted in dramatically improved facial esthetics and occlusal relationships.
本病例报告描述了一名 25 岁女性的治疗过程,她存在 II 类错颌畸形,主要表现为下颌骨发育不足和轻度覆合。上颌骨垂直向不足的患者通常采用上颌骨外科下复位作为治疗选择;然而,该患者的垂直向不足处于临界状态,采用下颌“三脚架”推进(术后下颌弓的整平)联合后退和下截骨颏成形术进行治疗。手术-正畸治疗计划结合美容牙科治疗,显著改善了面部美观和咬合关系。
