Determination of efficiency of orthodontic treatment by using engineering tools

Dental malocclusion and crossbite can result in aesthetic and functional problems. Up until recently, the characterisation of crossbite was performed on photographs and radiographs that are generally limited to 2D representations and an inaccurate determination of the distances between teeth. The advent of 3D scanners provides the possibility to enhance the accuracy and relevance of measurements performed on dental casts, enabling the study of the effectiveness of orthodontic interventions. A systematic description of the procedure used to scan maxillary casts is thus described in this work. The dental impressions are scanned by using a 3D scanner. The obtained STL files are hence imported into a suitable CAD software where the processing of the rendered casts and the determination of the required characteristics (palatal volumes and gingival planes’ surfaces) are performed. The variation of these values can thus be monitored on pre- and post-treatment casts, achieving the goal of the work.
