The Accuracy of Direct Digital Intra-oral Scanning Measurements Compared to Measurements on Study Models

Start date: December 2014
Phase: N/A
Study type: Interventional

The purpose of this study is to compare the accuracy of measurements derived from a commercially available direct intra-oral scanning system with those taken from plaster study models, and to compare cost implications of both systems. The investigators will test the hypotheses: - There is no systematic difference between measurements taken from the Trios scanner and study models. - There is no difference in the cost of producing digital models.
