Analysis of Learning Curve for Digital Intraoral Scanning: Dental Students v/s Clinicians

Abstract

Introduction: The integration of digital technology in dentistry, particularly through the use of intraoral scanners, has revolutionized diagnostic and treatment processes. These scanners enhance patient comfort, reduce the risk of impression distortion, and improve communication with dental laboratories. However, mastering this technology requires an understanding of the science, technique & repeated use associated with its adoption, especially among different age groups of clinicians.

Aim and Objective: This study aims to compare the learning curves of final-year dental students and experienced clinicians in mastering digital intraoral scanning using the Virtuo Vivo, Straumann Corp (Basel, Switzerland) intraoral scanner. By analyzing the time required for full-arch digital impressions over a series of sessions, the study seeks to elucidate differences in adaptation, efficiency, and proficiency between these two groups.

Methods: The study involved 10 final-year dental students and 10 clinicians, all with no prior experience in digital scanning. Participants underwent comprehensive theoretical education and practical demonstrations on the intraoral scanner Virtuo Vivo, Straumann Corp (Basel, Switzerland) before performing digital impressions of upper and lower dental arches on volunteer subjects. The scanning process followed a standardized protocol, and scanning times, the number of images captured, and error rates were meticulously recorded and analyzed across ten scanning sessions. A total of 200 scans were taken 2 scans per participants.

Results: The results of the study indicated that clinicians demonstrated higher initial proficiency and efficiency in using the Virtuo Vivo, Straumann Corp. intraoral scanner compared to dental students. Both groups showed significant improvement over the course of the study, but the rate of improvement was steeper for dental students. Accuracy of scans improved for both groups, with experienced clinicians maintaining a consistently higher level of precision throughout. The study confirmed that targeted training and practice could significantly enhance digital scanning skills, regardless of initial experience levels. Additionally, the reduction in error rates was more pronounced among dental students, highlighting their adaptability and capacity for rapid learning. The overall findings suggest that with proper training, even those new to the technology can achieve a high level of proficiency in digital intraoral scanning.

Conclusion: This study highlighted the initial advantage clinicians possess in digital intraoral scanning, attributed to their clinical expertise. However, dental students demonstrated significant learning and adaptation, showing substantial improvement over the study period. Both groups benefited from structured training, underscoring its critical role in fostering proficiency with digital technologies. The findings underscore the importance of integrating comprehensive digital training early in dental education to equip future practitioners with essential skills. This approach ensures that all clinicians, regardless of experience, can effectively utilize advanced digital tools to enhance patient care and clinical outcomes.
