This case report describes the orthodontic treatment of an adult patient with iatrogenic absence of the maxillary canines, moderate maxillary and severe mandibular dental crowding, a Bolton discrepancy with a large mandibular anterior excess, a maxillary right lateral incisor crossbite, and Angle Class II molar relationships. The treatment consisted of fixed appliance therapy, mandibular incisor extraction, tooth bleaching, and dental recontouring. This method of treatment maintained the patient's good facial appearance, improved the dental esthetics, and provided a good functional occlusion, eliminating the arch length and Bolton discrepancies and providing a good outcome with minimal undesirable effects.
本病例报告描述了一例成人患者的正畸治疗过程。该患者由于医源性缺失上颌尖牙，伴有中度上颌和重度下颌牙齿拥挤、Bolton 不调伴下颌前牙过大、上颌右侧侧切牙锁颌以及安氏 II 类磨牙关系。治疗包括固定矫治器治疗、下颌切牙拔除、牙齿漂白和牙体修整。这种治疗方法保持了患者良好的面部外观，改善了牙齿美观，提供了良好的功能咬合，消除了牙弓长度和 Bolton 不调，并取得了良好的效果，且副作用极小。
