Influence of Horizontal Intraoral Scan Bodies on the Trueness of Digital Impressions for Complete‐Arch Prostheses on Four Implants: An In Vitro Evaluation

This is the authors' abstract. We don't add key points for this paper.

H-ISBs did not perform better than V-ISBs in all scenarios. The interactions among ISB design, IOS type, and operator significantly affect the digital impression trueness. The discrepancies measured among the systems remain well below the currently accepted threshold for clinically relevant misfit, supporting the suitability of the horizontal configuration for complete-arch impressions.
