3D laser scanning of dental impressions / Matthew Athanassiadis.

Abstract

This research found that laser scanning of dental impressions using a split-impression technique is possible. It also found that here is no statistical difference between the four methods of representing dental arches. Therefore, plaster models, laser-scanned plaster models, combined laser-scanned half-impressions and CT-scanned full impressions are equivalent methods for representing dental arches. --p. 103.
