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.

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 ...

Influence of intraoral scanning duration on data accuracy
The Journal of Prosthetic DentistryThe use of intraoral scanners (IOSs) correlates with clinical outcome and patient satisfaction. While the accuracy of IOSs has been well evaluated, studies on the effect of scanning duration on data accuracy are limited.The purpose of this in vitro study was to investigate the relationship between different scanning durations and the accuracy of the ...

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.
