This study aimed to provide information on the accuracy of exported digital files with the different resolutions available in the CEREC 4.6.2 software obtained by means of an intraoral scanner (IOS), in addition to establishing differences between materialized models with different exported resolutions, and how these different exported files can influence finite element analysis (FEA) simulations. The possibilities of use in the realization of partial restorations, crowns and bridges are viable using impressions by intraoral scanners. The results of this review provide data on each of the systems currently available. Likewise, it aims to describe the different IOS systems used in addition to its advantages and disadvantages over con-ventional impressions for the manufacture of prosthetic restorations. This review of the literature aims to provide knowledge by collecting the findings of several studies on dental prostheses manufactured from intraoral digital impressions. It is expected that the use of these scanners generates an absolute digitalization in the fixed prosthodontics protocol. New technologies to design and machine fixed prosthesis are giving way to a higher frequency of digital impressions through intraoral scanners (IOS). Execution of this plan begins with the dental preparations and the impressions to obtain the working models.
