Regional difference in physiological roles of human temporal muscle related to three-dimensional bite force

Makoto Watanabe

The present study proposes to assess the regional differences existing in the activity of the human temporal muscle, during biting. The right temporal muscle was investigated in six male subjects, with normal dentition and without craniomandibular disorders. They were asked to bite arbitrarily, during which EMG, the direction and magnitude of bite forces were recorded. After analyzing the results, we concluded that each muscle region had different functions while biting and a proper dynamic range regarding bite-force directions.
