The aim of this study was to evaluate the association between various functional and occlusal parameters and sleep bruxism. Thirty-nine (39) sleep bruxism patients and 30 controls participated in this investigation. The assessment of sleep bruxism was performed using the Bruxcore Bruxism-Monitoring Device (BBMD) combined with a new computer-based analyzing method. Sixteen functional and/or occlusal parameters were recorded. With a mean slide of 0.95 mm in the sleep bruxism group and a mean slide of 0.42 mm in the control group (Mann Whitney U test; p<0.003), results solely demonstrated a significant group difference regarding the length of a slide from centric occlusion to maximum intercuspation. The results suggest that the slightly pronounced slide could be of clinical importance in the development of increased wear facets in patients with current sleep bruxism activity. Following further evaluation including polysomnographic recordings, the BBMD combined with this new analyzing technique seems to be a clinically feasible instrument that allows the practitioner to quantify abrasion over a short period.
本研究的目的是评估各种功能和咬合参数与睡眠磨牙症之间的关联。39名睡眠磨牙症患者和30名对照者参与了这项调查。使用Bruxcore磨牙症监测装置（BBMD）结合一种新的基于计算机的分析方法对睡眠磨牙症进行评估。记录了16项功能和/或咬合参数。睡眠磨牙症组的平均滑动为0.95毫米，对照组的平均滑动为0.42毫米（曼-惠特尼U检验；p<0.003），结果仅显示从正中咬合到最大牙尖交错位的滑动长度存在显著的组间差异。结果表明，在当前有睡眠磨牙症活动的患者中，这种稍明显的滑动在磨损小平面增加的发展过程中可能具有临床意义。经过包括多导睡眠图记录在内的进一步评估后，BBMD结合这种新的分析技术似乎是一种临床上可行的仪器，可让从业者在短时间内对磨损进行量化。
