This case report describes the treatment of a 33-year-old white man who had a skeletal Class III and dental Class II subdivision malocclusion caused by a retrognathic maxilla, with severe maxillary crowding, a highly placed maxillary left canine, mild mandibular crowding, and a bilateral posterior crossbite. Treatment was performed with a modified surgery-first approach, which included a short presurgical alignment phase for the correction of the significant maxillary crowding while controlling the incisal angulation, followed by LeFort I maxillary advancement surgery. The short presurgical orthodontic phase aimed at eliminating the anterior dental interferences before the maxillary advancement, and the use of the inherent increased bone turnover in the postsurgical phase helped to reduce the total orthodontic treatment time to 12 months. Pleasing esthetic results and a good functional occlusion were achieved.
本病例报告描述了一名33岁白人男性的治疗情况，该患者因上颌后缩导致骨骼III类和牙性II类亚类错牙合，伴有严重的上颌拥挤、高位上颌左尖牙、轻度下颌拥挤和双侧后牙反牙合。采用改良的手术优先方法进行治疗，包括在术前进行短期排齐阶段，以纠正明显的上颌拥挤并控制切牙角度，随后进行LeFort I型上颌前徙手术。术前短期正畸阶段旨在消除上颌前徙前的前牙干扰，术后阶段利用固有的骨转换增加有助于将正畸总治疗时间缩短至12个月。获得了令人满意的美学效果和良好的功能咬合。
