Scanning Distance Influence on the Intraoral Scanning Accuracy—An in Vitro Study
Materials, 2022 Intraoral scanners (IOS) have reached a point where their impact in the dental office cannot be denied. The distance between the tip of the IOS and the preparation may have implications on the accuracy of the digital model. The objective of this study was to evaluate the differences in accuracy between digital impressions in the scenario of different ...

Intraoral Scanning Systems: Need for Maintenance
The International Journal of Prosthodontics, 2017This study aimed to analyze a possible gain in accuracy in intraoral scanning systems by manufacturer calibration.A master model was scanned tenfold with a Lava Chairside Oral Scanner (3m ESPE) and a CEREC Bluecam suspected to be decalibrated. Thereafter the scanners were calibrated and the model was scanned again. An iTero system served as comparison.

Intraoral ultrasonic scanning as a diagnostic aid
Journal of Cranio-Maxillofacial Surgery, 1987Since ultrasonographic examination has the advantages of being non-invasive, rapid and easily reproducible, this technique can be a valuable aid in diagnosing oral lesions. However, the relatively large size of commercially available transducers and the acoustic attenuation by the air space within the oral cavity have been deterrents to the intraoral ...

Impact of orthodontic brackets on intraoral and extraoral scans
American Journal of Orthodontics and Dentofacial Orthopedics, 2022The purpose of this study was to evaluate whether the presence of orthodontic brackets influences the accuracy of digital models generated by intraoral and extraoral scanning from the same patients.Eighteen orthodontic patients in permanent dentition underwent full-arch intraoral scanning with a CEREC Omnicam scanner (Dentsply Sirona, York, Pa ...

Digital intraoral scanning technique for edentulous jaws
The Journal of Prosthetic Dentistry, 2018Few studies have evaluated direct digital scans of edentulous jaws using intraoral scanners because it is difficult to scan edentulous sites that are smooth and devoid of features. A scanning technique is introduced for making direct digital scans of edentulous jaws with intraoral scanners in patients with a broad palate.
