The aim of this study was to show a case of a Class III subdivision adult patient treated with clear aligners (CA) and the extraction of a lower bicuspid. A 19-year-old male with a class III canine and molar relationship on the right side and a deviation of lower dental midline to the left asked for an aesthetic treatment. He refused orthognathic surgical procedures, so he was offered a camouflage orthodontic treatment with the extraction of lower right first premolar to achieve a canine Class I relationship and to center the lower midline. The treatment was performed with clear aligners and the use of Class III elastics to maintain distal anchorage on the right side during the canine distalization. At the end of the treatment, the occlusal objectives were achieved.
本研究旨在展示一例使用透明牙套（CA）和拔除下双尖牙治疗的 III 类分牙患者。一名 19 岁男性，右侧为 III 类犬牙和磨牙关系，下颌中线偏左。他要求进行美学治疗。他拒绝接受正颌手术，因此，我们为他提供了以下治疗方案：拔除右侧下颌第一前磨牙，以实现犬牙 I 类关系，并将下颌中线居中，从而进行隐形矫正治疗。使用透明牙套和 III 类橡皮筋来维持右侧犬牙远移过程中的远中支抗。治疗结束时，达到了咬合目标。
