The purpose of this narrative review was to assess the internal fit of provisional restorations by evaluating the accuracy of two representative IOSs for single crowns and 3-unit FPD preparations. Relevant articles were gathered from a variety of sources, including manual cross-reference searches and textbooks, as well as electronic databases like PubMed, Scopus, Embase, the Cochrane library, and Science Direct. MeSH terms and keywords pertaining to "marginal fit," "primescan," "omnicam," and "intraoral scanner" were used in the search. The inclusion criteria were English language articles that fit the study's objectives and that were published between June 2022 and July 2007. Articles with low sample sizes and/or insufficient reporting and obscure methodology were excluded from selection. Following a comprehensive evaluation of all the included papers, 40 excellent articles were chosen for this review. The chosen articles explain the features of an intraoral scanner and help answer our stated questions about the most accurate method and appliances to use for scanning to best serve the prosthodontist.
