Abstract
Our experiment's aim was to make a three-dimensional (3D) analysis of a case with malocclusion and to simulate the orthodontic treatment with fixed poliaggregate appliance. We used intraoral photos, panoramic radiographs and lateral cephalograms which were processed in Rhinoceros Nurbs Modelling Tool v.5.0 Service Release 9. To create the 3D model we used the programs Keyshot v.5.0.86 with trial license, Adobe Photoshop CS6 v. 13 and SnagIT v. 12.2.0, requiring the application of several sequences of graphic processing. Individualizing the original 3D model consisted of customizing component elements, repositioning dental units, matching their alveoli, blocking them in three layers, creating jaw and mandible and positioning in occlusion. Customizing the 3D model showed the status of the chosen clinical case. In order to simulate the orthodontic treatment brackets and archwires were built and were placed on each maxillary and mandibular tooth. Our 3D model has many advantages, varied functionality, diagnostic and therapeutic importance.
