Investigations of Intraoral Scan Body Extensions. Effect of Design on the Accuracy, Usability, and Feasibility for Digital Full-Arch Implant Scans In Vitro.
OBJECTIVES To evaluate the effect of different scan body extension designs on the accuracy, usability, and feasibility of digital full-arch implant impressions in an edentulous mandibular model. Accuracy was expressed as trueness and precision, usability as scan time, and feasibility as the number of total scan failure...
