Influence of Light Scanning Conditions on Accuracy of an Intraoral Scanner
Now online in the Journal of Prosthodontics, Drs. Marta Revilla‐León, Sai Ganesh Subramanian, Mutlu Özcan, and Vinayak Raman Krishnamurthy studied the influence of ambient light scanning conditions on the trueness and precision of an intraoral scanner.
The authors selected one complete dentate patient and a complete maxillary arch vinyl polysiloxane impression was obtained. Digital scans of the patient were performed using an IOS (TRIOS 3; 3Shape) with 4 lighting conditions.
The results of the study showed significant difference in the trueness and precision values across different lighting conditions. Room lighting obtained the lowest absolute error compared with the other lighting conditions tested. The authors also conclude that ambient light scanning conditions influence differently depending on the extension of the digital scans made.
