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

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

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 .

Study Population

Population selected for this study is any healthy male/female participant with complete set of non fractured maxillary or mandibular permanent teeth first molars included.

Description

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.
