Abstract

                Intraoral scanners (IOS) have emerged as a key component of digital dentistry, providing a reliable alternative to conventional impression techniques. The accuracy of intraoral scans is influenced by multiple factors. Scanning protocols are a relevant factor in achieving accurate results with these devices and supporting successful outcomes. This narrative review aims to investigate the effect of different scanning strategies on the trueness and precision of intraoral scans. This work is a narrative review of in vitro studies, clinical trials and comparative analyses focused on intraoral scanning patterns. Research was conducted through PubMed and Medline using Boolean operators with terms like “intraoral scanners”, “digital impressions” and “scanning strategies.” Only English language articles from the were included. Relevant literature addressing intraoral scanning strategies was identified and synthesized for qualitative analysis. Scanning strategy is a significant factor affecting the accuracy of intraoral scans, especially in complex cases. Optimization of scanning strategies can reduce scanning errors and improve final outcomes. However, variability among studies and scanner systems indicates the need for standardized guidelines and further research.

Keywords: Intraoral Scanner, Scanning Strategy, Scan Pattern, Trueness, Precision.
