Evaluation of the Scanning Accuracy of Scanners Operating With Different Scanning Technologies in Mandibular and Maxillary Edentulous Ridges

Summary

This study aims to evaluate the scanning accuracy of scanners equipped with Active Triangulation, Confocal Microscopy, and Multi-Direct-Capture technologies.

Department of Prosthetic Dentistry, Faculty of Dentistry, Ege University , 30 patients who applied for a complete removable denture and met the inclusion criteria will have conventional impressions taken. The resulting master model (reference scan) will be scanned using an industrial scanner with high scanning accuracy (E4 lab scanner, 3shape, Denmark) to obtain digital data. Edentulous ridges; Active Triangulation (Medit i700, Seoul, South Korea), Confocal Microscopy (Trios 5, Henry Schein Dental, Gillingham, Kent, UK), and Multi-Direct-Capture technologies (iTero Lumina, Align Technologies, San Jose, California, USA) will be scanned three times using the scanning protocols recommended by the manufacturers and digitized. All digital data obtained will be evaluated using Geomagic (Studio 2015; 3D Systems Inc., Darmstadt, Germany) 3D analysis software to match the reference data and verify its accuracy according to the accepted reference measurement.

Interventions

OTHER

Trios 5

Each patient's edentulous ridges are planned to be scanned three times with Trios 5.To ensure optimum accuracy, scans were performed in a standard dark environment in accordance with the manufacturer's scanning protocols.

OTHER

iTero Lumina

Each patient's edentulous ridges are planned to be scanned three times with iTero Lumina.To ensure optimum accuracy, scans were performed in a standard dark environment in accordance with the manufacturer's scanning protocols.

OTHER

Medit i700

Each patient's edentulous ridges are planned to be scanned three times with Medit i700.To ensure optimum accuracy, scans were performed in a standard dark environment in accordance with the manufacturer's scanning protocols.

OTHER

E4 Lab Scanner

Conventional measurements will be taken from each patient, and the resulting master model (reference scan) will be scanned using an industrial scanner with high scanning accuracy (E4 lab scanner, 3shape, Denmark) to obtain digital data.
