The aim of the study was to study the dimensional accuracy of temporary artificial crowns made using the Asiga Max UV 3D printer, the KaVo ARCTICA CAD/CAM system, using digital images of the experimental model obtained by the intraoral laser scanner iTero Cadent and temporary artificial crowns made by the laboratory method of hot polymerization. The dimensional accuracy of artificial crowns was studied using the computer program MeshLab. The Friedman criterion was used for statistical analysis of the obtained data. The results of our research indicate a high dimensional accuracy of temporary artificial crowns made using modern digital technologies (CAD/CAM systems, intraoral laser scanning and 3D printer), compared to artificial crowns made by the traditional method of hot polymerization of acrylic plastic with a significance level of p<0,05.
Keywords:digital technologies in dentistry, digital impressions, CAD/CAM, intraoral scanner, 3D printing.
