One of the most important stages of prosthetic, implantoprosthetic or orthodontic treatment is the exact replication of the conditions occurring in the patient’s oral cavity. In dentistry today, this procedure can be carried out using either traditional impression methods or an intraoral scanner. The aim of the study is to discuss, on the basis of literatureę, the advantages and disadvantages of digital impressions obtained with intraoral scanners compared to impressions obtained. The literature review was carried out using the Scopus and PubMed databases, using the following key words: intraoral scanner, digital impression, conventional impression, CAD/CAM. Intraoral scanning has many advantages over traditional impression methods, such as time saving, accuracy, elimination of the need for disinfection, better communication with the dental technician and the patient. However, scanning is not without its drawbacks. These include: inaccuracies in scanning the prosthetic base to fabricate prostheses consisting of more than 4-5 elements or full-arch restorations, difficulties in mapping subgingival areas or root canals, time-consuming and expensive process of implementing digital techniques in everyday professional practice.
