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

Completed

• Conditions: Evaluate and Compare the Accuracy of Digital Dental Models Generated From Plaster Casts by Two Different Scanning Techniques
• Interventions: Device: linear measurement

• Registration Number: NCT05874947
• Lead Sponsor: Cairo University

Brief Summary

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 .
