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

Condition(s) studied

Investigational drug(s) / intervention(s)

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.

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.

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.

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.

Study 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.

Eligibility

Primary outcome measure(s)

• Accuracy of Intraoral Scanners Compared With Reference Extraoral Scanner — Two months
  The primary outcome is the trueness (accuracy) of three intraoral scanners (Trios 5, Medit i700, iTero Lumina) in capturing edentulous maxillary and mandibular arches. Accuracy will be assessed by comparing the surface deviation of intraoral scan data to the reference dataset obtained from the extraoral laboratory scanner of a conventional stone cast. Mean root-mean-square (RMS) error values (measured in micrometers, µm) will be calculated for each scanner relative to the reference to quantify the deviation.
