Impact of sleep bruxism on masseter and temporalis muscles and bite force

Abstract: The present data suggest that SB negatively altered the masticatory muscles' functions. Based on the results of this research, it can be concluded that individuals with SB showed decreased EMG activity in the masticatory muscles.

“…During the recording of electromyographic data, they remained seated in a comfortable chair with their feet flat on the floor and their palms on their thighs. The Frankfort horizontal plane was kept parallel to the ground . All the subjects performed maximum lateral and protrusive jaw movements with respect to the canine and anterior guides.…”

“…The Frankfort horizontal plane was kept parallel to the ground. 21 All the subjects performed maximum lateral and protrusive jaw movements with respect to the canine and anterior guides. After a correct positioning of the jaw was achieved, the electromyographic activity was recorded for a predetermined time (rest for 4 seconds and right and left maximum laterality with dental contact, and maximum protrusion with dental contact for 10 seconds).…”

“…Para que o sistema mastigatório funcione adequadamente, é necessário que a musculatura do sistema estomatognático esteja em perfeito equilíbrio [5] . O sistema extrapiramidal atua nos movimentos mandibulares de maneira que a mastigação possa ocorrer em ciclos regulados, rítmicos e espontâneos, sendo necessário o estímulo de sinais sinápticos aferentes, que controlam o movimento [6,7] .…”

“…Na protrusão, observou-se o padrão do comportamento muscular essencial para preservar a posição com maior ativação dos músculos masseteres se comparada com os músculos temporais [11]. Esses resultados são discordes com o padrão descrito, onde os músculos temporais são mais ativos que os músculos masseteres [12]. O GIII apresentou maior atividade eletromiográfica em comparação ao GI e GII, com diferença estatística significante para o músculo temporal esquerdo.…”
