The temporomandibular joints of seven patients exhibiting clinical signs and symptoms of TMJ dysfunction were scanned using a 0.3T magnetic resonance system. Images were obtained with the mandible in open and closed positions. Patients were also scanned wearing a maxillary occlusal splint. Images obtained showed varying degrees of disc displacement and pathological changes in the joint depending on the severity of the clinical symptoms presented. In all patients, splints were shown to distract the joint slightly and place the condyle, disc and fossa in a more favourable relationship.
使用0.3T磁共振系统对7名表现出颞下颌关节紊乱临床体征和症状的患者的颞下颌关节进行扫描。在下颌处于张开和闭合位置时获取图像。患者佩戴上颌咬合板时也进行了扫描。根据所呈现临床症状的严重程度,获得的图像显示关节存在不同程度的盘移位和病理变化。在所有患者中,咬合板均显示出可使关节稍有分离,并使髁突、关节盘和关节窝处于更有利的关系。
