ABSTRACT
Anterior displacement of the temporomandibular joint disc
is associated with a general remodeling of the joint's soft tissues. The
anterior part of the posterior attachment becomes fibrotic. The external shape
and the internal architecture of the disc change in characteristic ways. The
disc appears to overlie more of the lateral pterygoid muscle than is normal.
The capsule connecting the anterior band of the disc to the condyle appears to
be elongated.
