The aim of this case report is to describe the treatment of a patient with skeletal Class III malocclusion with maxillary retrognathia using skeletal anchorage devices and intermaxillary elastics. Miniplates were inserted between the mandibular lateral incisor and canine teeth on both sides in a male patient aged 14 years 5 months. Self-drilling mini-implants (1.6 mm diameter, 10 mm length) were installed between the maxillary second premolar and molar teeth, and Class III elastics were used between the miniplates and miniscrews. On treatment completion, an increase in the projection of the maxilla relative to the cranial base (2.7 mm) and significant improvement of the facial profile were observed. Slight maxillary counterclockwise (1°) and mandibular clockwise (3.3°) rotations were also observed. Maxillary protraction with skeletal anchorage and intermaxillary elastics was effective in correcting a case of Skeletal Class III malocclusion without dentoalveolar side effects.
本病例报告的目的是描述使用骨锚固装置和颌间弹力牵引治疗一名患有上颌后缩的骨性III类错牙合患者的情况。在一名14岁5个月的男性患者双侧下颌侧切牙和尖牙之间植入微型钢板。在上颌第二前磨牙和磨牙之间植入自攻微型种植体(直径1.6 mm,长度10 mm),并在微型钢板和微型螺钉之间使用III类弹力牵引。治疗结束时,观察到上颌相对于颅底的突度增加(2.7 mm),面部轮廓有显著改善。还观察到上颌轻微逆时针旋转(1°)和下颌顺时针旋转(3.3°)。使用骨锚固和颌间弹力牵引进行上颌前牵引有效地矫正了一例骨性III类错牙合,且无牙槽骨副作用。
