title: [Current knowledge of the temporomandibular joint morphology: clinical implications].
abstract: The internal derangements of the temporomandibular joint (TMJ) are characterized by a displaced disk that acts as a obstacle to the joint movement causing a sound (click) associated with limited mandibular opening. These disorders can be accompanied by pain. The joint internal derangements are the most common inflammatory pathology of the TMJ, observing morphological changes, disk displacement, even in asymptomatic individuals. In this process seems to be involved the lateral pterygoid muscle. Our discussion will attempt to relate the possible sequence of morphological events that occur in these disorders and their influence on observed changes in the posterior region of the joint.
