Comparison of 3D accuracy of three different digital intraoral scanners in full-arch implant impressions.

Purpose: This study aimed to evaluate the performance of digital intraoral scanners in a completely edentulous patient with angled and parallel implants.

Materials And Methods: A total of 6 implants were placed at angulations of 0°, 5°, 0°, 0°, 15°, and 0° in regions #36, #34, #32, #42, #44, and #46, respectively, in a completely edentulous mandibular polyurethane model. Then, the study model created by connecting a scan body on the implants was scanned using a model scanner, and a 3D reference model was obtained.
