Vibratory feedback - based inhibition system for sleep bruxism

利用咬合矫治器研制了一种磨牙症相关振动反馈系统，用于抑制睡眠磨牙症。为了检验该系统的实用性和有效性，本研究选择了美国睡眠医学学会推荐的标准(国际睡眠障碍分类-2)诊断为磨牙症的4名受试者作为研究对象。他们被要求在使用该系统的家庭环境中监测他们的睡眠磨牙症，为期3周。所有人都能够在没有实质性问题的情况下完成所有的记录过程，该系统有效地抑制了睡眠磨牙症，而不会引起实质性的睡眠障碍。如果他们不再提供反馈，磨牙症的减少是否会继续下去，以及施加的力量水平是否是诱导抑制的最佳水平，仍有待未来的研究确定。

A bruxism-contingent vibratory-feedback system, which used occlusal appliances, was developed for inhibition of sleep bruxism. In order to test the utility and validity of this system, 4 subjects, who were diagnosed as having sleep bruxism according to the criteria suggested by American Academy of Sleep Medicine (The International Classification of Sleep Disorders-2) were recruited to this study. They were asked to monitor their sleep bruxism at their home environment using this system for 3 weeks. All of them were able to finish all recording sessions without substantial problem and this system effectively inhibited sleep bruxism without inducing substantial sleep disturbance. Whether the reduction in bruxism would continue if they device no longer provided feedback and whether the force levels applied are optimal to induce suppression remain to be determined in the future studies.
