Details and patient eligibility

About

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 .

Enrollment: 24 patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients with maxillary or mandibular complete permanent dentition
• Partially edentulous patients provided the dentition are complete from the first molar to the first molar.

Exclusion criteria

• Patients with fractured teeth, attrition and/or erosion affecting the anatomical points
• Patients having non-anatomic restorations that may alter cusp anatomy affecting the accuracy of measurements consequently.
