Abstract

Jaw muscle forces in horizontal isometric jaw movements with maximum voluntary efforts were evaluated in fifteen healthy male participants (mean age: 24.7 years) in the postures of sitting upright with headrest, without headrest and supine. Horizontal jaw muscle forces were registered with intraoral force transducer. Force data were analyzed with ANOVA statistically. The results were as follows:<BR>1. The maximum horizontal forces depended on the directions of the jaw movements (posteriorly pull. mean±S.D.; 16.3±13.3kgf>posterolaterally pull: 11.0±6.0kgf≅aanterolaterally push: 10.7±6.0kgf≅a anteriorly push: 10.2±6.9kgf, p<0.0001). However, no significant effects were found between the postures.<BR>2. It seems that the results will give us the fundamental data to assess the horizontal jaw function.
