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 dentures: A protocol based on intraoral scans
The Journal of Prosthetic Dentistry, 2021The use of intraoral scans for complete denture fabrication may improve patient comfort, clinic ergonomics, and laboratory efficiency. Techniques have been reported regarding specific tasks related to the use of intraoral scans for digital dentures, but an integrated workflow is still lacking.

Influence of scanning strategies on the accuracy of digital intraoral scanning systems
International journal of computerized dentistry, 2013The digital intraoral impression is a central part in today's CAD/CAM dentistry. With its possibilities, new treatment options for the patient is provided and the prosthetic workflow is accelerated. Nowadays, the major issue with intraoral scanning systems is to gain more accuracy especially for larger scan areas and to simplify clinical handling for ...

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.

Learning curve of intraoral scanning by prosthodontic residents
The Journal of Prosthetic Dentistry, 2020The use of intraoral scanning (IOS) to replace conventional impressions has become popular. However, the learning time required to use these devices effectively is unknown.The purpose of this in vitro study was to investigate the learning rate, plateau, and difficulty level over repetitive IOS among prosthodontic residents.Twenty participants with no ...

The Journal of Prosthetic Dentistry
The accuracy of intraoral scanners (IOSs) can be affected by operator handling; however, the scanning area and accuracy discrepancies acquired at different scanning distances and angulations among IOSs remain uncertain.The objective of this in vitro study was to compare the scanning area and scanning accuracy of the intraoral digital scans obtained at ...

The repeatability of periodontal imaging with intraoral ultrasound scanning
Clinical Oral InvestigationsUltrasound is a non-invasive and low-cost diagnostic tool widely used in medicine. Recent studies have demonstrated that ultrasound imaging might have the potential to be used intraorally to assess the periodontium by comparing it to current imaging methods.
