Abstract

As TMJ closed lock is self-limiting, a conservative strategy should be used.

All patients in this study satisfied RDC-TMD criteria for anterior disc displacement without reduction (closed lock). Diagnosis was based on history and clinical examination. When in doubt, diagnosis was confirmed using MRI. Forty-nine patients were randomly assigned to either a physical therapy group or control group. It took six years to recruit the patients because of the stringent inclusion criteria. In the physical therapy group, 1) exercises and massage were performed, and 2) strategies to minimise parafunction habits were reinforced. Both these activities were carried out over nine sessions. Pain and function were measured at baseline and at 3, 6, 12, 26, and 52 weeks. In both test and control groups, all pain variables significantly decreased and all masticatory functions improved. Intensive physical therapy had no additional beneficial outcomes.
