Comparison of internal derangements of the TMJ with occlusal findings.

Two hundred five patients were examined because of temporomandibular joint pain and dysfunction. Arthrograms were performed on 222 joints (188 unilateral and 17 bilateral). No significant differences were found between arthrographic groups with respect to Angle classification, horizontal and vertical overlap, posterior tooth wear, missing posterior teeth, cuspid-protected occlusion, balancing-side contacts, deflective occlusion, and clenching of the teeth. Tilted teeth on the contralateral side were more common in cases of reducing meniscal dislocation than in cases of normal meniscus position or of nonreducing meniscal dislocation.
