This study was designed to investigate the short-term effects of stabilization appliances on parafunctional oral motor behaviour (bruxing and clenching) during sleep in patients with and without signs of temporomandibular disorders (TMD). Results revealed that stabilization appliances do not stop nocturnal parafunctional activities in both groups of patients. Active wear facets on the guide ramps of appliances were created by bilateral mandibular excursions. The extension of these facets indicate that the mandible moves laterally far beyond the edge-to-edge contact relationship of the canines during eccentric bruxism. Results also indicate that, with the exception of temporomandibular joint (TMJ) clicks, stabilization appliance therapy is effective in eliminating the signs of TMD evaluated.
本研究旨在调查稳定矫治器对有和没有颞下颌关节紊乱病(TMD)体征的患者睡眠期间副功能口腔运动行为(磨牙和紧咬)的短期影响。结果显示,稳定矫治器并不能阻止两组患者夜间的副功能活动。通过双侧下颌运动在矫治器导斜面上形成了活动磨损面。这些磨损面的延伸表明,在偏侧磨牙时,下颌向外侧移动的距离远远超过尖牙的边缘对边缘接触关系。结果还表明,除了颞下颌关节(TMJ)弹响外,稳定矫治器治疗在消除所评估的TMD体征方面是有效的。
