Subject. Modern digital technologies allow us to significantly automate the process of creating prosthetic devices. First, digital images of the patient's dental rows are obtained, then the future prosthesis is virtually modeled and made using a subtractive method using CAD/CAM, or an additive method using a 3D-printer. Objective ― conducting a comparative assessment of the time spent by an orthopedic dentist and a dental technician for the production of artificial dental crowns obtained using digital and traditional technologies. Methodology. The patients were divided into four groups according to the method of manufacturing temporary artificial crowns-from a composite material Protemp 4 using a silicone key, using the CAD/CAM-system KaVo ARCTIC from polymethylmethacrylate VITA CAD-Temp multicolor, using a 3D-printer Asiga Max UV from a biologically compatible photopolymer material NextDent C&B MFH and a laboratory method of cold plastic polymerization. For statistical analysis of the results obtained, the Kraskel―Wallis H-test and the Mann―Whitney W-test were used. In total, 40 medicinal artificial crowns were made, 10 in each group. Results. Based on the data obtained, it was found that for the manufacture of a dental artificial crown using the 3D-printer Asiga Max UV dentist orthopedist and dental technician should spend 38.8 ± 4.104 minutes, using CAD/CAM KaVo ARCTICA-29.0 ± 3.162 minutes, using the laboratory method ― 71.6 ± 4.502 and using a silicone key ― 62.8 ± 5.613. Conclusions. The obtained data allowed us to conclude that the production of a temporary artificial crown with the use of modern digital technologies (CAD/CAM-systems, intraoral laser scanning and 3D-printer) requires less time compared to traditional methods of manufacturing a prothesis (p<0.0166667).
