Abstract

Clinicians are familiar with limitation of opening mouth caused by temporomandibular disorders. Sometimes, patients also complain of difficulty in closing mouth. Difficulty in closing mouth can be caused by anterior, posterior disc displacement, and subluxation of temporomandibular joint (TMJ). In this report, we presented a patient who had a difficulty in both opening and closing mouth. The patient complained of TMJ noises and intermittent limitation of opening mouth, and inability to get teeth back into maximal intercuspal position. Magnetic resonance images revealed that the left TMJ had an anterior disc displacement with relative posterior disc displacement. We reviewed the possible causes, signs and symptoms, and treatment for difficulty in closing mouth with related literatures.
