TMJ Anatomy Reconstruction and Kinematics - Anatomy of the TMJ (right-side fossa, condyle, and ramus shown from superior view) was reconstructed from MR slices. MR scans were segmented for extraction and vectorial description of anatomical structures as well as for determination of the reference common to MRI and jaw tracking. Animation of the TMJ was achieved by means of mathematical transformations, using the computer to calculate continuously the spatial positions of all vertices of polygons describing the recorded surfaces. Lines depict the jaw closing paths of three landmarks: Lateral pole of condyle (blue), condylion (green) and medial pole of condyle (red).
