The pathophysiology of mandibular dislocation involves the combination of three factors: loosening of the capsule and the TMJ ligaments, a prominent eminence, and muscular spasm.Initially, loosening of the capsule and ligaments allows the condyle to perform non-physiological and excessive motions, bypassing the articular eminence. This condition can be seen during simple activities such as laughing and yawning, during long dental consultations, during orotracheal intubation, and in episodes of vomiting. The treatment of chronic symptomatic TMJ hypermobility may be organized into; bony alteration, alteration of associated musculature and alteration of the ligaments.
