title: Computer-monitored radionuclide tracking of three-dimensional mandibular movements. Part II: experimental setup and preliminary results--Posselt diagram.
abstract: This article described a new method to track mandibular movements using a computer-assisted radionuclide kinematics technique. The usefulness of various image-enhancement techniques is discussed, and the reproduction of physiologic displacements is shown. Vertical, lateral, and protrusive envelopes of motion of a point on a tooth of a complete denture mounted on a semiadjustable articulator were measured. A demonstrative example of the validity of this approach is reproducing the motion of the mental point, which clearly evidences the Posselt diagram.
