Intraoral scanning devices applied in fixed prosthodontics

Abstract

Workflow in fixed prosthesis requires a strict compliance of the exploration, diagnosis and treatment plan processes. Execution of this plan begins with the dental preparations and the impressions to obtain the working models. New technologies to design and machine fixed prosthesis are giving way to a higher frequency of digital impressions through intraoral scanners (IOS). It is expected that the use of these scanners generates an absolute digitalization in the fixed prosthodontics protocol. This review of the literature aims to provide knowledge by collecting the findings of several studies on dental prostheses manufactured from intraoral digital impressions. Likewise, it aims to describe the different IOS systems used; in addition to its advantages and disadvantages over conventional impressions for the manufacture of prosthetic restorations. The results of this review provide data on each of the systems currently available. The possibilities of use in the realization of partial restorations, crowns and bridges are viable using impressions by intraoral scanners.
