近年来，有关颞下颌关节(TMJ)在正畸治疗中的研究已有不少报道，但尚未建立起完善的诊断和治疗体系，在临床上往往造成相当大的困难。此例中的患者在驾驶汽车时睡着并与卡车相撞，导致全身挫伤、脑震荡、下颌体中线骨折和下颌骨髁突双侧骨折。由于非手术复位是不可能的，所以进行了下颌髁突切除术，当尝试正畸治疗以改善作为事故后遗症持续存在的开放咬合时，获得了良好的结果，如下所述。1.开放咬合通过正畸治疗得到纠正，遗留的后遗症也得到解决。2.手术复位过程中摘除下颌骨髁突，消除了张口障碍、TMJ疼痛和TMJ噪声。患者能够安然无恙地进行日常生活，几乎没有意识到颌骨活动受限，即使在进行了正畸治疗后，这种情况也没有改变。
In recent years there have been many reports on studies related to the temporomandibular joint (TMJ) in orthodontic treatment, but an adequate system of diagnosis and treatment has yet to be established, and they often cause considerable difficulty clinically. The patient in this case report sustained generalized contusions, a cerebral concussion, a midline fracture of the mandibular corpus, and bilateral fractures of the condylar process of the mandible when he fell asleep while driving a car and collided with a truck. Because non-surgical reduction was impossible, mandibular condylectomy was performed, and when orthodontic treatment was attempted to improve the open bite that persisted as a sequela of the accident, the favorable results were obtained, as described below. 1. The open bite was corrected by the orthodontic treatment, and the impairment that remained as a sequela resolved. 2. The mandibular condyles were removed during surgical reduction, and the mouth opening disturbance, the TMJ pain, and the TMJ noise resolved. The patient was able to go about his everyday life unimpaired, with hardly any awareness of limitation of jaw movement, and this situation remained unchanged even after the orthodontic treatment was performed.
