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.

The Journal of Prosthetic Dentistry, 2021
A technique to merge facial and intraoral digital scans guided by an additively manufactured intraoral scan body is described. The technique facilitates facially driven treatment planning of restorative procedures in situations where a cone beam computed tomography scan is not indicated.

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 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.

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 ...

System Requirements for Intraoral Ultrasonic Scanning
2020Ultrasound is a technology driven imaging modality that leaps with innovations in computing, both hardware and software, integration, i.e. miniaturization, as well as engineering advances, such as analog–digital conversion, improvements in dynamic range, signal to noise, etc. Dental ultrasound is in its infancy. No ultrasound scanner modifications have
