The authors treated 80 patients (85 joints) with closed-lock of the temporomandibular joint internal derangement, by mandibular manipulation technique. Among the 80 patients, 24 patients (25 joints) were treated by manipulation after pumping and hydraulic pressure to the upper joint cavity. Treatment of 61 joints (71.8%) satisfied our criteria for success: 1. More than 36 mm of interincisal opening, 2. Good anterior translation of the condyle, and 3. Complete or very significant resolution of pretreatment pain. Comparison of the success group and the treatment failure group showed that the success group was younger and had a shorter history of clicking and locking.
