Abstract:<\/strong> Dental scanners, particularly intraoral scanners (IOSs), serve as the core devices in digital dentistry, and their accuracy directly determines the clinical fit and long-term prognosis of prosthetic restorations, orthodontic appliances, and implant-supported prostheses. Based on the ISO 5725 accuracy evaluation system (trueness and precision), this review systematically summarizes publicly published Chinese and English literature on the accuracy of dental scanners. From six dimensions\u2014scanning technology, hardware and software, operator factors, patient oral conditions, environmental conditions, and scanning strategies\u2014the causes of various accuracy problems are analyzed and targeted countermeasures proposed. Current evidence indicates that the trueness and precision of dental scanners for single-tooth and quadrant-level scans have reached clinically acceptable levels; however, full-arch and complete-arch implant scans remain limited by cumulative stitching errors, soft-tissue interference, and the moist intraoral environment. Optimizing scanning paths, strict moisture control, application of scanning-aid materials, regular device calibration, standardized operator training, and the introduction of calibration auxiliary devices can significantly improve scanning accuracy. Future research should focus on standardized accuracy evaluation protocols, novel optical sensing technologies, and improved full-arch scanning algorithms.<\/p>\n
