Occlusal splints are commonly used for the treatment of nocturnal bruxism. This study investigated the effects of hard and soft occlusal splints on nighttime muscle activity. The nocturnal muscle activity of ten participants was recorded while wearing a hard and then a soft occlusal splint. The hard occlusal splint significantly reduced muscle activity in eight of the ten participants. The soft occlusal splint significantly reduced muscle activity in only one participant while causing a statistically significant increase in muscle activity in five of the ten participants.
牙合夹板常用于治疗夜间磨牙症。本研究调查了硬式和软式牙合夹板对夜间肌肉活动的影响。在十名参与者佩戴硬式牙合夹板然后再佩戴软式牙合夹板时，记录其夜间肌肉活动情况。硬式牙合夹板使十名参与者中的八人肌肉活动显著降低。软式牙合夹板仅使一名参与者的肌肉活动显著降低，同时却使十名参与者中的五人肌肉活动出现统计学上的显著增加。
