Effect of scanning-aid agents on the scanning accuracy in specially designed metallic models: A laboratory study.

PLoS ONE, 2022
The advent of intraoral scanning methods has caused a paradigm shift in dentistry. However, despite their many advantages, intraoral scanners cannot accurately recognize the metallic surfaces of prothesis.

Accuracy of intraoral scans of edentulous jaws with different generations of intraoral scanners compared to laboratory scans

The Journal of Advanced Prosthodontics, 2021
Purpose of this in vitro study was to determine the accuracy of different intraoral scans versus laboratory scans of impressions and casts for the digitization of an edentulous maxilla.A PEEK model of an edentulous maxilla, featuring four hemispheres on the alveolar ridges in region 13, 17, 23 and 27, was industrially digitized to obtain a reference ...

Intra-oral scanning and CAD/CAM prosthesis fabrication

Annali di Stomatologia, 2018
The acronym Cad-Cam stands for Computer-Aided Design and Computer-Aided Manufacturing. In 1970, Dr. Francois Duret and his colleagues were the first to develop a Cad-Cam dental system, later named the Sopha system (Sopha BioConcept, Inc. Los Angeles). In

Evaluating the accuracy of three intraoral scanners using models containing different numbers of crown-prepared abutments

Journal of Dental Sciences, 2022
Background/purpose: The scanning accuracy of intraoral scanners’ data collection plays a key role in the success of the final treatment. However, few studies start from scanning technology itself to directly evaluate it.
