ABSTRACT

Disc displacement is one of the most common type of Temporomandibular joint arthropathy. The precise alignment of condyle–disc assembly is important for the proper functioning of temporomandibular joint. Posterior disc displacement is a condition in which disc tissue is located between the posterior surface of the condyle and post glenoid tubercle. Clinical symptoms of Posterior disc displacement includes lack of occlusion on the affected side, deviation of the mandible, pain on palpation, and large or nearly average mouth opening or interincisal distance. The etiopathogenesis of this condition is idiopathic. However, different predisposing factors include, trauma, forceful wide opening like yawning, lack of anterior prominence of the disc, disc adhesion, and perforation of the disc. This review article enlightens on the etiology, clinical features and treatment options of posterior disc displacement in temporomandibular joint, to help clinicians in proper diagnosis and treatment planning of the condition.
