Accuracy of CBCT Imaging and Intraoral Scanner in Dental Plaster Casts Digitization: A Validity and Reliability Study

Accuracy of CBCT Imaging and Intraoral Scanner in Dental Plaster Casts Digitization: A Validity and Reliability Study

The Objective of this study is to evaluate the accuracy of CBCT and intraoral scanner, in digitization of dental plaster casts, by comparing them to desktop optical scanner as a gold standard.

The Objective of this study is to evaluate the accuracy of CBCT and intraoral scanner, in digitization of dental plaster casts, by comparing them to desktop optical scanner as a gold standard.

Planmeca CBCT Modality, Haron 3DISC intraoral scanner will be used as index tests, and Medit T710 desktop optical scanner will be used as the gold standard.

STL files from test scanning modalities will be compared using the surface matching software (Geomagic control X). The surface matching software will automatically register the two compared STL files together using the best-fit alignment tool and will generate the 3D compare for the surface comparison between them.

Inclusion Criteria:

• Adult dental casts with complete dentition and/or partially edentulous regions.
• Maxillary and mandible casts are both included.
• Intact casts without voids, cracks, or visible porosities

Exclusion Criteria:

• Casts of pediatric patients.
• Completely edentulous casts.
• Casts with hypodontia, supernumerary teeth or fractured teeth.
• Casts with retainers, metallic appliances, or partial dentures.
• Casts with voids, fractures, cracks or visible porosities.
