This study describes a multidisciplinary approach for correcting a severe Class II malocclusion with reduced mandibular transverse dimension. A 35-year-old woman presented with an increased overjet, complaining chiefly of forwardly placed upper front teeth and unpleasant smile esthetics. The patient had a convex profile with severe mentalis strain on lip closure. Intraoral examination indicated a bilateral Class II canine relationship, scissor bite, and narrow lower arch. The skull lateral view assessment revealed a skeletal Class II relationship with reduced lower facial height. According to the diagnostic records and after consultation with the patient, surgically assisted expansion of the mandibular symphysis with a bone distractor, comprehensive orthodontic treatment, and combined jaw surgery were planned, followed by dental implant placement and prosthetic full-mouth rehabilitation. Restorative dentistry, orthodontics, and orthognathic surgery were the 3 disciplines that helped in achieving the best esthetic and functional results in this patient.
本研究描述了一种多学科方法,用于矫正下颌横向尺寸减小的严重安氏II类错牙合畸形。一名35岁女性前牙覆盖增大,主要抱怨上前牙前突及微笑美观不佳。患者侧面轮廓凸,闭口时颏肌紧张明显。口腔检查显示双侧安氏II类尖牙关系、剪刀状咬合及下牙弓狭窄。头颅侧位片评估显示骨骼安氏II类关系,面下高度减小。根据诊断记录并与患者协商后,计划采用骨撑开器进行手术辅助下颌联合部扩弓、全面正畸治疗及联合颌骨手术,随后进行牙种植体植入及全口义齿修复。修复牙科、正畸学和正颌外科是帮助该患者获得最佳美观和功能效果的三个学科。
