Comparing the accuracy of five Intraoral scanners with digital laboratory scanners

Abstract

Digital impression techniques are computerized methods used to capture 3D images of dental restorations, implants, and orthodontic appliances.

These techniques are revolutionizing the field of restorative dentistry. involve the use of digital scanners to capture images of the patient&#39, s oral structures, which can then be used to create restorations such as crowns, bridges, and veneers.

A maxillary typodont cast was used to simulate the patient’s mouth vinylpolysiloxane impression was made of the typodont cast and poured to fabricate stone casts.

The stone. casts were scanned by five IOSs (Medit i500, Medit i600, 3D shining, Carestream 3600, Eightieth Helios600) and one EOS (Optical smart vinyl) to obtain digital casts.

Reference teeth (distance between two centrals, distance between right central and right canine, distance between left central and left canine distance between two canines) dimensions were measured on the digital casts by PTK opera software and compared to measurements of the stone cast done by stereomicroscope[1]
