A study is made of the clinical and radiological characteristics of 16 patients with osteoarthrosis (OA) of the temporo-mandibular joint (TMJ). The study comprised those patients satisfying the diagnostic criteria for OA proposed by Stegenga et al. in 1989. The patients were subjected to a clinical and radiological diagnostic protocol (including the obtainment of magnetic resonance imaging data). The most relevant clinical findings were the detection of crepitants in 93.8% of cases, with a reduction in mandibular movement range. Radiology in turn identified joint surface alterations in 62% of cases on the right side, and in 68.8% of the patients on the left side. The joint disc dynamic position study showed anterior displacement without reduction in 50% of cases in the right joint and in 43.8% of patients in the left joint. In conclusion, patients with OA of the TMJ present joint sounds and a reduced mandibular movement range &endash; the salient radiological characteristic being altered joint morphology.

Keywords : Osteoarthrosis; temporomandibular joint.
