Malik J, et al. - The authors compared the accuracy (ie precision and trueness) of full-arch impressions fabricated using either a conventional polyvinyl siloxane (PVS) material or 1 of 2 intraoral optical scanners. Improved mean accuracy was exhibited by the conventional full-arch PVS impressions compared to 2 direct optical scanners. Findings did not reveal any notable differences between the 2 digital impression methods.
