详细描述
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.
