Abstract
The aim of the study was to ascertain whether there is any correlation between occlusal abnormalities with dysfunction of the masticatory apparatus. (DMA) 137 young people between 16-19 years of age were examined, including 57 with DMA and 80 without DMA. The diagnosis was established with the agreement of the International Headache Society (IHS) criteria and directories of
the American Academy of Orofacial Pain. (AAOP). The occlusal conditions were evaluated with the help of the computer aided system T-Scan II (Tekscan, Inc, Boston, USA). According to this method occlusal point contacts (premature contacts) were evaluated at the beginning of the occlusion (centric relation-CR). At this time percentage distribution of the relative net force between teeth
were determined. Teeth contacts with the maximum rel ative force along the dental arch were also recorded. In this way premature traumatic contacts were determined. There were also evaluated areas of support for the particular teeth or groups of the teeth in the maximum intercuspal position (MIP). The center of occlusal forces
(COF) in MIP were then recorded. Finally percentage distribution of the values of the resultant occlusal force moments, acting on both sides of the dental arch, were evaluated. As normal differences in these values less than 9 % between bothsides of the dental arch were accepted. The other groups were defined on the basis of the differences in the values of both sides of the dental arch in
the range: 10-19% as a satisfactory group, 20-29% as a moderate group, 30-39% as a high degree group and finally more than 40% as a very high degree group. The obtained results were submitted for statistical analysis. No correlations were found between occlusal
abnormalities and DMA.
