Internal Derangement of the Temporomandibular
Joint: New Perspectives on an Old Problem

ABSTRACT: Internal derangement of the temporomandibular joint is a condition in which there is an altered anatomic relationship of the articular disc to the mandibular condyle, articular eminence and the other anatomic components of the temporomandibular joint. Unfortunately, this common condition is often misunderstood as a disease entity itself requiring treatment and for many clinicians, has become the central focus of temporomandibular joint pathologies. Since a significant number of individuals who are perfectly functional with no symptoms have temporomandibular joint internal derangement, the question of the clinical significance of this finding needs to be clarified. Internal derangements occur when there is breakdown and failure of articular tissues resulting in altered joint biomechanics. The external factors which lead to tissue failure and internal derangement can ultimately result in pain and limitation of range of motion caused by synovitis, osteoarthritis, adhesions and disc degeneration. The presence of internal derangement should be considered a sign that there are biochemical changes in the articular tissues that are leading to tissue failure and biomechanical alterations in joint function. Do all patients with internal derangement require treatment? Which patients with internal derangement require treatment? If a patient with internal derangement requires treatment, when should they should they be treated and how? The focus of this presentation will be to review current research on the cause of temporomandibular joint internal derangements and the clinical significance of this entity.
