Since the first successful attempts in the 1980s to create virtual models and to find their practical application, this branch of dentistry has progressed significantly. The dynamic development of digitalization is aimed not only at facilitating the work of the dentist and the technical laboratory, but also at eliminating errors that may occur during the multi-stage process of traditional impression taking. Despite significant advances in material science, the conventional impression is still difficult to take, is often laborious and uncomfortable for the patient. An alternative method that has been developed over the years is taking a virtual impression and computer planning of prosthetic restorations. The aim of the study is to review the directions of development and possibilities of using intraoral scanners in everyday practice. A short description of these devices is presented, taking into account their advantages and disadvantages. Also included is the comparison of intraoral scanners with conventional methods of taking impressions and extraoral scanners. Digital dentistry is a rapidly evolving field that offers many possibilities in specific clinical cases, but requires further upgrades to extend the current range of indications for use with CAD/ CAM systems.
