扪诊头颈部肌肉和颞颌关节,可以检查出咬合关系的性质和颞颌关节功能紊乱的来源。扪诊法扪诊时需双侧同时进行,唯有翼外肌只能单侧检查,扪诊时手指的用力要稳定而柔和。检查要点包括肌肉的结构、协调、体积,以及收缩的强度和顺序。颞肌和嚼肌收缩的强度和顺序与颌间关系及咬合方式有关系。如果一侧肌肉不收缩,就是诊断的主要依据。 Auscultation of the head and neck muscles and the temporomandibular joint can detect the nature of occlusion and the source of temporomandibular joint dysfunction. Palpation palpation when both sides need to be carried out at the same time, only the wing outside the muscle can only be unilateral examination, the palpation of the finger force to be stable and gentle. Checkpoints include muscle structure, coordination, volume, and intensity and sequence of contraction. Intensity and order of contraction of the temporal and massenge muscles are related to intermaxillary and occlusal modes. If the side of the muscle does not shrink, it is the main basis for diagnosis.
