Abstract

Abstract: Objective: Stomatology is a highly practical course, and the application of digital technology brings new opportunities to the teaching of dentistry. The aim of this study was to explore the application of digital technology in the standardized training of resident dentists in prosthodontics. Methods: This experiment focused on 45 resident trainees who participated in standardized training for resident dentists at the Stomatology Hospital, Zhejiang University School of Medicine, and they were divided into a control group and an experimental group. The control group received traditional theoretical teaching and operational demonstration, while the experimental group teachers used digital intraoral scanning technology to guide the tooth preparation of porcelain fused to metal crown. The quality of tooth preparation was evaluated with five aspects: posture, edge shape, point line angle, degree of aggregation, and preparation amount. Results: There was a significant difference (P<0.05) between the experimental group (92.26±2.97)and the control group (89.91±4.20) in the performance of the full crown tooth preparation assessment. Conclusions: Digitally guided teaching of tooth preparation of porcelain fused to metal crown can effectively improve students’ learning initiative, mastery and application of theoretical knowledge, clinical thinking and practical abilities, and provide foundation for ultimately cultivating resident dentists with excellent clinical job competence.
