Evaluation of Impression Accuracy: Digital Scanner Versus Analog Technique

The goal of this study is to evaluate the accuracy of intraoral impressions obtained using the Trios 3Shape® and Carestream CS 3600™ scanners, as well as traditional analog impressions using polyvinyl siloxane (PVS), in comparison to a gold standard represented by a laboratory scanner in 51 dental models from 42 patients affected by partial edentulism who required at least two implants. Researchers compare Trios 3Shape®, Carestream CS 3600™ and polyvinyl siloxane (PVS) to see if there is a different accuracy.
