: To compare the effect of canine guidance or group function on diaphragm activity, heart rate, and oxygen saturation during awake teeth grinding at different body positions. : Fifty healthy participants, 25 with canine guidance and 25 with group function, were included. Bilateral electromyographic (EMG) recordings of the diaphragm (DIA) during awake teeth grinding were performed in standing, seated upright, and right lateral decubitus positions. Simultaneously, heart rate and oxygen saturation were measured. : EMG activity of the DIA muscle was similar in the working side and non-working side between participants with canine guidance and group function in the different body positions studied. The heart rate and oxygen saturation showed no significant differences between the two groups. : EMG activity of the DIA muscle, the heart rate, and oxygen saturation during teeth grinding are not significantly influenced by the type of laterotrusive occlusal scheme.
比较不同身体姿势下清醒磨牙时尖牙引导或组牙功能对膈肌活动、心率和血氧饱和度的影响。纳入50名健康参与者，其中25名具有尖牙引导，25名具有组牙功能。在站立、直立坐姿和右侧卧位时对清醒磨牙期间的双侧膈肌肌电图（EMG）进行记录。同时，测量心率和血氧饱和度。在不同身体姿势下，具有尖牙引导和组牙功能的参与者之间，工作侧和非工作侧的膈肌肌电活动相似。两组之间的心率和血氧饱和度无显著差异。磨牙期间膈肌肌电活动、心率和血氧饱和度不受侧方咬合方案类型的显著影响。
