RESUMO
OBJECTIVES: The present study was designed to investigate the correlation between the bony morphology of the mandibular condyle and the occurrence of temporomandibular joint (TMJ) idiopathic anterior dislocation. STUDY DESIGN: A comparative retrospective study was conducted among 14 patients presenting idiopathic anterior dislocations (study group) and 15 patients who did not suffer from any TMJ disorders (control group). All patients underwent a multidetector computed tomography scan demonstrating the full extent of their joints. The scans of 58 joints were reconstructed and analyzed by tools available in Dolphine3 software. Mandibular condyle size and volume were measured, and its shape was characterized. RESULTS: Shape, width, length, height, and volume of the mandibular condyles did not differ statistically between the study and control groups. CONCLUSION: Mandibular condyle morphology does not affect TMJ idiopathic anterior dislocation.
