Trueness and Precision of Four Intraoral Scanners in Oral Implantology: A Comparative in Vitro Study.

ABSTRACT:

Purpose

The aim of this study was to compare the trueness and precision of four intraoral scanners used in oral implantology.

Methods

Two stone models were prepared, representing a partially and a totally edentulous maxilla, with three and six implant analogues, respectively, and polyether-ether-ketone (PEEK) cylinders screwed on. The models were digitized with an industrial scanner (IScan D104I®) used as a reference, and with four intraoral scanners (Trios®; CS 3500®; Zfx Intrascan®; Planscan®). Five scans were taken for each model, using each different intraoral scanner. All datasets were loaded into reverse-engineering software (Geomagics 2012®), where intraoral scans were superimposed on the reference model, to evaluate general trueness, and superimposed on each other wi
