Summary:

Over the last two decades, there have been major changes in the dental industry, due to the introduction of the CAD/CAM systems. As one of the key technologies, 3D scanners have emerged during the digital transformation. Their implementation enables the scanning of patients' unique jaws, to create custom prosthetic replacements. This paper describes the implementation of CAD/CAM systems in the dental industry with a special focus on dental scanners. An overview of the conducted experimental research on the accuracy of scanners for dental use is presented, and a methodology for the experimental part of the work has been created. In the experimental part, the method of experimenting is described in detail. Modeling of model for scanning, selection of model materials and model making are shown. Information on the reference scanner and comparison scanners are given and the 3D scanning process on the extraoral scanners and the intraoral scanner is described in detail. Frequent interruptions occurred during the intraoral scanner scan and no representative scans were obtained for comparison with the reference scan. Scans obtained by extraoral scanners were compared with a reference scan in a software for quality control. According to results the UP300 scanner showed the best accuracy. Finally, a discussion was held and the conclusion of the research was reached.
