Dislocation of the temporomandibular joint (TMJ; see the image below) is a painful condition that occurs when the mandibular condyle becomes fixed in the anterosuperior aspect of the articular eminence.
TMJ dislocation is due to either trauma (force against a partially opened mandible) or, more commonly, excessive opening of the mandible (such as may occur during yawning and dental procedures).
