The integration of digital technology in dental education has been recognized for its potential to address the challenges in training removable partial denture (RPD) design. RPD framework design is crucial to long-term success in the treatment of dentition defects, but traditional training methods often fall short of adequately preparing students for real-world applications.
This study aimed to evaluate the efficacy of a 3D simulation-based preclinical training software for RPDs in enhancing learning outcomes among first-year stomatology master's students, while also assessing user perceptions among students and faculty.
RTS (Yikchi Siu) is a preclinical training software that simulates the clinical process of treating patients with partial edentulism. In this study, 26 newly enrolled master's degree students in stomatology who volunteered to participate were randomly divided into a control group (n=13) and a training group (n=13). The training group used the RTS for 2 credit hours (90 min) of self-study, while the control group received theoretical lessons and case practice from an instructor. After 2 hours, both groups completed the theoretical knowledge and drawing tests for RPD simultaneously. Test results were evaluated and graded by 2 experts in prosthodontics. Both users and teachers filled out a questionnaire afterward about their training experience.
Participants in the training group obtained better final grades compared to controls (theoretical test: 88.8, SD 2.3; 85.7, SD 3.3, respectively; P=.01; drawing test: 89.8, SD 4.5; 85.1, SD 4.3, respectively; P=.01). The training group had a shorter completion time in the drawing test (12.6, SD 19 min; 17.7, SD 3 min, respectively; P<.001) but there were no significant differences in the completion times in the theoretical test (23.2, SD 2.2 min; 24.9, SD 2.8 min, respectively; P=.14). Students and faculty generally had a favorable opinion of the RTS.
The effectiveness of the RTS for newly enrolled master's degree students in stomatology to understand and apply their knowledge of RPD framework design was validated; the system was well received by both students and faculty members, who reported that it improved the effectiveness and convenience of teaching.
数字技术在牙科教育中的整合因其在应对可摘局部义齿（RPD）设计培训挑战方面的潜力而得到认可。RPD框架设计对于牙列缺损治疗的长期成功至关重要，但传统培训方法往往不足以让学生充分为实际应用做好准备。
本研究旨在评估一种基于3D模拟的RPD临床前培训软件在提高口腔医学硕士一年级学生学习成果方面的效果，同时评估学生和教师的用户感知。
RTS（Yikchi Siu）是一款模拟治疗部分牙列缺失患者临床过程的临床前培训软件。在本研究中，26名自愿参与的新入学口腔医学硕士研究生被随机分为对照组（n = 13）和培训组（n = 13）。培训组使用RTS进行2学分小时（90分钟）的自学，而对照组接受教师的理论授课和病例实践。2小时后，两组同时完成RPD的理论知识和绘图测试。测试结果由2名口腔修复学专家进行评估和评分。之后，用户和教师都填写了一份关于他们培训经历的问卷。
与对照组相比，培训组参与者获得了更好的最终成绩（理论测试：分别为88.8，标准差2.3；85.7，标准差3.3；P = 0.01；绘图测试：分别为89.8，标准差4.5；85.1，标准差4.3；P = 0.01）。培训组在绘图测试中的完成时间更短（分别为12.6，标准差19分钟；17.7，标准差3分钟；P < 0.001），但在理论测试中的完成时间没有显著差异（分别为23.2，标准差2.2分钟；24.9，标准差2.8分钟；P = 0.14）。学生和教师对RTS总体评价良好。
验证了RTS对新入学口腔医学硕士研究生理解和应用RPD框架设计知识的有效性；该系统受到学生和教师的好评，他们报告说它提高了教学的有效性和便利性。
