Surface muscle potentials for occlusal activities in dentistrywere measured by the muscle potential instrument. Four kinds of muscles were taken upfor measurement in the present work, which are the right-and-left masseter and cowlmuscles. The higher activation was observed in the work-side and these reference datawere applied to development of an incremental constitutive law of muscle employed in afinite element scheme. For ordinal occlusal activities, this law should be sufficientto describe the time-dependent mechanics without any inertia, and the results newlysuggest that natural length of muscle was changed to a cyclic loading and then thehysteresis loop becomes stationary
