Digital occlusal evaluation in patients with temporomandibular joint disorders.

The etiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD. Objective: The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system. Materials and methods: Sample consisted of 44 persons, divided into investigative group of 20 TMD patients and control group of 24 subjects without TMD. Main task of T-Scan II computerized occlusal analysis system was to record every patient?s occlusion and estimate static occlusal parameters: centre of occlusal force, asymmetry index of maximum occlusal force and occlusion time. These results were compared between groups, data related to patients? complaints and clinical symptoms. The analysis was carried out using Mann-Whitney U, Kruskal-Wallis and Chi-square tests. Results: Averages of the center of occlusal force in TMD subjects were 6.55 ± 0.99 mm, in the control group -5.88 ± 0.69 mm; asymmetry index of maximum occlusal force averages: 15.90 ± 2.71 and 12.93 ± 1.88; occlusion time: 0.281 ± 0.036 seconds and 0.236 ± 0.022 seconds respectively. There were no statistically significant differences between two groups but they were found in the center of occlusal force and asymmetry index in the two groups (p<0.05). Conclusion: Values of occlusal parameters in TMD patients were higher than in healthy subjects but differences were not statistically significant. Values of the center of occlusal force distance and asymmetry index of occlusal force in TMD patients wiht pain in the TMJ were significantly higher than in the control group.
