Comparative evaluation of the accuracy of the dental arch display using modern intraoral three-dimensional scanners

BACKGROUND: At present, modern dentists used dental intraoral three-dimensional (3D) scanners routinely in their daily work. Obtaining an optical 3D image of the teeth and dentition helps avoid errors at stage obtaining traditional silicone impressions significantly reduces level discomfort during procedures. Intraoral scanner systems are commercially available today. Despite advantages over impressions, accuracy obtained total subtotal prosthetics on upper lower jaw still questionable.
 AIM: This study aimed to evaluate scanning models patients using determine currently digital devices that optimal terms price quality.
 MATERIAL AND METHODS: The reference scan (master model) was model a patient with full made by additive 3D-printing technology laboratory scanner. To out shrinkage photopolymerization materials, resulting scanned same day selected for study. results were compared control group. Based measurements points, average error value relative master its precision calculated each In addition values, parameters frontal chewing sections calculated, as well arc error, which equal difference values discrepancy points maximum minimum obtained. cost availability domestic market, under sanctions policy foreign countries, also considered.
 RESULTS: CEREC Primescan AC showed best according discrepancies. It has 13.727.34. 18.8 microns, discrepancies area 18 6.8 respectively. 3Shape Trios 3 closest accuracy, 16.285.94 microns. Aoralscan 42.0818.34 65 areas 33 55.1 Emerald S Mode C had 35.8422.29 higher than Medit i500 3; however, better (18.34 microns versus 22.29 microns). According comparison MeshLab program, smallest median distances (18 TRIOS differed from standard 29 41 microns.
 CONCLUSION: scanner, is among analogs category, makes it most affordable surgical, orthodontic, orthopedic fields. leader premium involved market.
