A Comparative Study of the Accuracy of Dies Made from Digital Intraoral Scanning vs. Elastic Impressions: An In Vitro Study.

Purpose: To compare the dimensional accuracy of dies generated from digital intraoral scans with dies generated from conventional polyvinyl siloxane (PVS) impression material.

Materials And Methods: A machined metal die was impressed 10 times using PVS, and scanned 10 times using the iTero Cadent system and 10 times using the LAVA C.O.
