1. A method of tracking jaw motion of a person, comprising the steps of: (a) applying a plurality of microsphere targets to a tooth surface of the upper dentition of the person and a tooth surface of the lower dentition of the person; (b) obtaining at least two sets of stereoscopic images of the microsphere targets on the upper and lower teeth surfaces, wherein each set is captured at a different time during jaw motion; and (c) analyzing the at least two sets of stereoscopic images to mathematically characterize jaw motion of the person.
