This study was designed to investigate the effects of the occlusal splint on parafunctional oral motor behavior (grinding and clenching) during sleep in patients with bruxism and craniomandibular disorders. The results revealed that the splint does not stop nocturnal bruxism. In 61% of the patients, wear facets on the splint were observed at every visit (2-week intervals) and in 39%, from time to time. The wear facets reappeared in the same location with the same pattern and were caused mainly by grinding. The extension of the facets showed that, during eccentric bruxism, the mandible moved laterally far beyond the edge-to-edge contact relationship of the canines.
本研究旨在调查咬合板对磨牙症和颅下颌紊乱患者睡眠期间口腔副功能运动行为（磨牙和紧咬）的影响。结果显示，该咬合板并不能阻止夜间磨牙症。在61%的患者中，每次就诊（间隔2周）时均观察到咬合板上有磨耗面，39%的患者则偶尔出现。磨耗面会在相同位置以相同模式再次出现，主要由磨牙引起。磨耗面的扩展表明，在偏侧磨牙症期间，下颌向外侧移动的距离远远超出了尖牙的边缘对边缘接触关系。
