title: [Occlusal contact changes before and after orthodontic treatment of TMJD patients in children and adolescents].
abstract: Occlusal contacts were examined in a sample of 32.8-17 Years old TMJD patients before and after orthodontic treatment. Computer-aided video system was applied to the silicone occlusal record obtained in the intercuspid position to assess the quantitative and qualitative changes of occlusal contacts. The results showed that after orthodontic treatment, the mean number of contacts on anterior teeth decreased, the mean area per contact decreased, the location of contacts on centric stops increased and the contacts on inclined plane were decreased. All of these indicated that the occlusal stability increased after orthodontic treatment.
