Title: Methods and composition for tracking jaw motion

Abstract: In a method according to an embodiment of the present invention, a plurality of microsphere targets is applied to a surface of a tooth on the upper dentition of a person and a tooth surface of the lower dentition of the person. At least two sets of stereoscopic images are obtained, where the microsphere targets are visible in the field of view of each image. The center position of the beads is photogrammetrically determined in three dimensions for each set using the images taken from perspective positions. The change in bead positions in the sets of stereoscopic images is analyzed to mathematically characterize the jaw motion of the person.
