Intraoral scanning of the edentulous jaw without additional markers: An validation study on scanning precision and registration of an intraoral scan with a cone-beam computed tomography scan.

Purpose: A fully digital approach to oral prosthodontic rehabilitation requires the possibility of combining (i.e., registering) digital documentation from different sources.

Validation of 3D documentation of palatal soft tissue shape, color, and irregularity with intraoral scanning.

Objectives: The purpose of this study was to assess the feasibility of 3D intraoral scanning for documentation of palatal soft tissue by evaluating the accuracy of shape, color, and curvature.

Materials And Methods: Intraoral scans of ten participants' upper dentition and palate were acquired with the TRIOS® 3D intraoral scanner by two observers. Conventional impressions were taken and digitized as a gold standard.
