Restrictions on mandibular movements, such as the fibrous adhesions or bone fusion between condyle, disc, glenoid fossa, and eminence, are caused by ankylosis of the temporomandibular joint (TMJ), which is an intracapsular union of the disc–condyle complex to the temporal articular surface. It is a severe and incapacitating ailment that can lead to issues with speech, eating, swallowing, looking well, and maintaining personal hygiene.
