The effects of occlusal adjustments on the myoelectric activity of the anterior temporal and masseter muscles, with the mandible at rest and during maximal clenching in the intercuspal position (ICP), were studied in 24 nocturnal bruxism patients. Before the occlusal adjustment, the patients were treated with a flat occlusal splint for chronic craniomandibular disorders. The results revealed that within the short term the occlusal adjustment, in terms of increased number of occlusal contacts and teeth in contact in ICP, did not change the postural activity, whereas, on average, the level of activation of the jaw elevators, in terms of normalized electromyogram, increased during maximal clenching in ICP. The increase of activity was more pronounced in the masseter muscle than in the anterior temporal muscle.
在24名夜间磨牙症患者中，研究了咬合调整对颞前肌和咬肌肌电活动的影响，下颌处于休息状态以及在牙尖交错位（ICP）最大紧咬时的情况。在进行咬合调整之前，患者接受了用于治疗慢性颅下颌疾病的平面咬合板治疗。结果显示，短期内，就ICP中咬合接触数量和接触牙齿数量的增加而言，咬合调整并未改变姿势活动，然而，平均而言，就标准化肌电图而言，在ICP最大紧咬期间，升颌肌的激活水平增加。咬肌的活动增加比颞前肌更明显。
