Abstract

Patients seek orthodontic treatment to correct unesthetic and asymmetric smiles because even a minimal cant of 4 is well perceived by a layperson. This case report describes a nonsurgical orthodontic management of iatrogenic occlusal canting in a 22-year-old female, who developed it during a previous orthodontic treatment for an impacted canine. The iatrogenic cant was corrected by the intrusion of the left mandibular segment followed by extrusion of left maxillary segment using mini-implants. Mini-implants were inserted in the mandibular left buccal segment (the first between canine and premolar, the second between the second premolar and first permanent molar), and the intruded mandibular posteriors were stabilized with the help of stainless-steel ligature (0.012″ SS) tied to the mini-implant. The expected correction of the occlusal cant, asymmetric gingival and tooth exposure, and soft tissue lip cant were corrected resulting in a significant improvement in smile aesthetics at the end of orthodontic treatment. After a follow-up period of 24 months, the results were stable.

微型种植体辅助正畸矫正一名年轻成人的唇部和咬合不正：病例报告。

患者寻求正畸治疗来矫正不美观和不对称的微笑，因为即使是最小的 4 度倾斜，外行人也能很好地感知。本病例报告描述了对一名 22 岁女性先天性咬合倾斜的非手术正畸治疗。该患者在之前的犬齿撞击正畸治疗中出现了先天性咬合歪斜，通过使用微型种植体植入左下颌部分，然后挤出左上颌部分来矫正先天性咬合歪斜。微型种植体被植入下颌左侧颊面（第一颗在犬齿和前磨牙之间，第二颗在第二前磨牙和第一恒磨牙之间），植入的下颌后牙用不锈钢结扎带（0.012 英寸 SS）固定在微型种植体上。预期的咬合倾斜、牙龈和牙齿暴露不对称以及软组织唇倾斜都得到了矫正，从而在正畸治疗结束时显著改善了笑容的美观度。经过 24 个月的随访，效果稳定。
