ABSTRACT
Background:
We compare the accuracy of new intraoral scanners (IOSs) in full-arch digital implant impressions.Methods:
A master model with six scan bodies was milled in poly(methyl methacrylate), measured by using a coordinate measuring machine, and scanned 15 times with four IOSs PrimeScan, Medit i500, Vatech EZ scan, and iTero. The software was developed to identify the position points on each scan body. The 3D position and distance analysis were performed.Results:
The average and ± standard deviation of the 3D position analysis was 29 µm ± 6 µm for PrimeScan, 39 µm ± 6 µm for iTero, 48 µm ± 18 µm for Mediti500, and 118 µm ± 24 µm for Vatech EZ scan (p < 0.05).Conclusions:
All IOSs are able to make a digital complete implant impression in vitro according to the average misfit value reported in literature (150 µm); however, the 3D distance analysis showed that only the Primescan and iTero presented negligible systematic error sources.Key words
