This study aims to evaluate long-term effects of using an occlusal splint in patients with sleep bruxism (SB), using surface electromyography (EMG) of masseter and temporalis muscles, as well as the Helkimo Index. The subjects were 15 individuals aged from 19 to 29 years, bearers of SB, with presence of signs and symptoms of temporomandibular disorders (TMD), which never have used occlusal splints. The subjects answered the Helkimo's Index and underwent EMG before and after 60 days of occlusal splints use. There was no indication of a significant decrease in mean EMG levels over the therapy in the muscles. A significant decrease in TMD signs and symptoms were observed in SB patients after 60 days of occlusal splints therapy.
本研究旨在通过使用咬肌和颞肌的表面肌电图（EMG）以及赫尔基莫指数，评估使用咬合板对睡眠磨牙症（SB）患者的长期影响。研究对象为15名年龄在19至29岁之间的SB患者，伴有颞下颌关节紊乱病（TMD）的体征和症状，且从未使用过咬合板。研究对象回答了赫尔基莫指数问卷，并在使用咬合板60天前后接受了肌电图检查。在治疗过程中，未发现肌肉平均肌电图水平有显著下降。咬合板治疗60天后，SB患者的TMD体征和症状有显著减轻。
