Umber Nawaz, Muhammad Yahiya Qureshi, Muhammad Anwar Masood Behr.


In symptomatic subjects, Disc reduction of temporomandibular joint is usually bilateral, directed to anterior or anterior lateral positions, and reduction is present in 76% of the cases. A common characteristic of the articular disc in cases of disc displacement is a thickening of its posterior band. A 22 years old female presented to Physical therapy OPD with complaint of acute onset of pain and sudden locking of jaw from 3-4 days. She was a known case of hyper laxity. On Examination she had clicking/crepitation's in the area of Temporomandibular Joint. Morning stiffness with slow movement of mandible. She feels fatigued, but no pain. She also finds difficulty while mouth opening. When she opened her mouth, she experiences locked jaw in the morning only and subside afterwards. There was no luxation of the mandible. On Visual analogue scale the pain intensity measured was 6/10.
Manual forward mandible protrusion in grade I and lateral shift mobilization with mandible active movement from mid to end range. Isometric exercise as a home plan was given to the patient with stretching of the mandible. After 5 session follow-ups, the patient`s pain was 2/10. The patient was able to do mouth opening without any restrictions. Other symptoms were also improved.
Disc displacement with reduction of temporomandibular joint is commonly seen globally, especially in lower socioeconomic countries. Over the top, this disease is ignored by the patients, dentist/ maxillofacial surgeons as well as physical therapist.
