The TMJ has unique biomechanical characteristics, as the
bilateral TMJs must function together under compressive
loads while undergoing large-scale movement. MRI allows
for noninvasive evaluation of the joint and has the
ability to evaluate soft tissues such as the articular
disc and its congruity relative to the condyle in closed
and open mouth position. The biomechanics of the osseous
structures in the normal TMJ are well demonstrated using
high resolution dynamic 3D cube sequence and involves
translation and rotation of the mandibular condyle in
the anterior to posterior direction and tissue
deformation due to compression.
