Aim. Based on the literature about complete and removable partial dentures fabricated using CAD/CAM technology and techniques, as well as differences between the clinical and laboratory steps compared with the conventional method, the advantages and disadvantages of CAD/CAM removable dentures are summarized. Material and Methods. An electronic search of English language literature was performed using PubMed/MEDLINE for original papers published since 1994 with the following specific search terms: CAD/CAM complete denture, CAD/CAM removable partial denture, and digital denture. Using a variety of keywords that aimed to narrow the topic, 307 publications were initially searched. For the main topic, the abstracts of these 307 articles were scanned, and 27 publications were selected for reading in detail. The study covered Polish original papers. Results. Based on the analysis of the available articles, it was found that CAD / CAM technology, which has been used for over a decade in the design and manufacture of fixed prostheses, has become increasingly popular in the case of removable dentures. The most important centres that have introduced the CAD / CAM dentures are Wieland Dental, Avadent, Dentca, and Ceramill. Each of them has introduced a different algorithm for clinical practice and laboratory work that aims to design and make digital prostheses. Conclusions. Introducing CAD / CAM technology for the digital planning and fabrication of dentures can shorten the treatment process compared with conventional methods. Despite the undoubted technological leap observed in recent years, associated with the introduction of new systems such as additive and subtractive manufacturing, these methods have several limitations. Due to the low availability (only a few companies like Wieland Dental, Avadent, Dentca, and Ceramill fabricate dentures using CAD / CAM), there is no long‑term observation of patients who are treated with these dentures. It is necessary to continue research which should ultimately determine the clinical usefulness of CAD / CAM removable dentures.

Key words: CAD/CAM complete denture, CAD/CAM removable partial denture, digital denture.
