DISK DISPLACEMENT WITH REDUCTION– Alteration, usually abrupt, of the disc-condyle structure relationship during mandibular translation. This is usually associated with reciprocal clicking. Reproducible joint noise at different positions during opening and closing. Soft tissue imaging may reveal disc reduction on opening.

DISC DISPLACEMENT WITHOUT REDUCTION– Altered disc-condyle structural relationship that is maintained during translation (acute or chronic). Soft tissue imaging may reveal absence of reduction.

DISK DISPLACEMENT WITH REDUCTION– Alteration, usually abrupt, of the disc-condyle structure relationship during mandibular translation. This is usually associated with reciprocal clicking. Reproducible joint noise at different positions during opening and closing. Soft tissue imaging may reveal disc reduction on opening.

DISC DISPLACEMENT WITHOUT REDUCTION– Altered disc-condyle structural relationship that is maintained during translation (acute or chronic). Soft tissue imaging may reveal absence of reduction.

• ACUTE– Usually extreme pain, limited opening, absence of joint noise, deflection to the affected side on opening, and limited lateral excursion to the opposite side.

• CHRONIC– Usually little or no pain, history of joint noise and/or limited opening, absence of joint noise other than possible crepitus and limited opening and lateral excursion to the opposite side (slight).
