Dentists are increasingly fabricating computer engineered complete dentures (CECDs) or digital dentures nowadays. The introduction of computer-aided design and computer-aided manufacturing (CAD-CAM) technology to clinical and dental laboratory operations has numerous benefits, including improved clinical outcomes. The aim of this review was to analyze and summarize the results of clinical research related to the production of dental crowns, specifically focusing on the differences between CAD-CAM technology and traditional methods. The databases searched for this review were Medline/PubMed, Cochrane Library, SciELO, Web of Science, and Embase. The review was conducted following the criteria established by the Cochrane Collaboration and in accordance with the Preferred Reporting Items for Narrative Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Conclusions were derived and provided based on the findings of this narrative review.
