Research Abstract

This research introduces a new method to produce 3-D TMJ movement graphics with combination of 3-D CT data and six-degree-of-freedom jaw movement data, and to analyze TMJ. The acrylic jig attached the ceramic balls for combining movement data and morphological data was made. It took almost 1 hour for setting appliance, CT scanning and jaw movement. Visualization and animation provide an easier understanding of TMT kinematics and ioint space could be analyzed.
