Volumetric Evaluation of 3D Models Generated by Different Surface Treatment Protocols

The objective of this study was to compare the volume of three-dimensional (3D) models generated by different scanners and computational modeling protocols. Eight dry mandibles were scanned by five different computed tomography (CT) scanners and by a 3D-scanner. Three-dimensional models were generated, received different surface treatment processes, and the final volume of the 3D models was compared. The results show that there was no significant difference among the volume of the 3D models generated by the different CT scanners and surface treatment techniques, however, the model volume generated by the 3D-scanner show the highest volume. It can be concluded that the different combinations of surface treatment protocols did not determine differences in the model volume generated by different CT and CBCT scanners and that the 3D-scanner determined the highest volume models.
