T scan digital occlusion analysis in orthodontics - a pilot study

Digital dentistry is a standard of modern practice. T scan III is the most accurate digital occlusion analyzer for purposes of implantology, prosthetics and orthodontics. Numerous occlusal analyzers have been used through history. One of them is articulating paper, which registers contacts as dots and shapes outlined on dental surfaces which don’t provide information about the intensity of the contacts. T scan III sophisticated sensors accurately obtain 2D and 3D images of dental contacts and assess intensity of the forces that develop during intercuspation. The aim of this pilot clinical study was to assess the occlusal parameters in patients with class II and III who are candidates for orthodontic therapy and to compare them with normal occlusion parameters (control group). In this way we wanted to help orthodonts to make better therapeutic decisions and more precise and effective plan of therapy. The obtained results showed that the bite load in malocclusions is more dominant on one side of the dental arch, in class III it was at the right side, while in class II it was in a higher percentage on the left side. The upper molars bear the highest force intensity, which was more equilibrated in normal occlusion, while it was unbalanced in class II and III. We came to conclusion that in class II and III it is necessary to balance the occlusion on the left and right side of the dental arch, as well as to correct the orientation of the forces affecting the dentition, while in the control group we proved that the occlusion was more balanced with regular force distribution during the intercuspation.
