Accuracy of Different Technologies for Dental Cast Digitization; CBCT Versus Desktop Optical 3D Scanner

Cairo University24 enrolled

Overview

The objective of this study is to evaluate and compare the accuracy of digital dental models generated from plaster casts by two different scanning techniques including Cone Beam Computed Tomography (CBCT) and extraoral Scanner (EOS) . The comparison between the two techniques is assessed by orthodontic arch space analysis using linear measurements for arch length and width .
