A 38-year-old female patient presented with temporomandibular joint (TMJ) pain, bilateral clicking and intermittent locking. The patient was treated with a splint in order to decrease the symptoms and to obtain a proper disk-condyle relationship. The effect of the splint therapy was investigated after one month and after one year and five months using magnetic resonance imaging (MRI) with splints in place. After treatment for one year and six months, the clicking sound of the right TMJ disappeared, and she became free from locking. With the aid of MRI, it was found that the disk of the right TMJ had changed from an anterior position with reduction to a superior position. In the left TMJ, the disk changed from an anterior position without reduction to an anterior position with reduction. MRI gave important information on the disk position and the efficacy of the splint therapy.
一名38岁女性患者出现颞下颌关节（TMJ）疼痛、双侧弹响及间歇性绞锁。为减轻症状并获得合适的盘 - 髁关系，对该患者进行了夹板治疗。在佩戴夹板的情况下，分别于1个月后、1年零5个月后使用磁共振成像（MRI）研究夹板治疗的效果。治疗1年零6个月后，右侧TMJ的弹响消失，且不再出现绞锁。借助MRI发现，右侧TMJ的关节盘已从可复性前移位变为上移位。左侧TMJ的关节盘则从不可复性前移位变为可复性前移位。MRI为关节盘位置及夹板治疗效果提供了重要信息。
