Abstract: Objective    To investigate the effectiveness of the digital techniques in the teaching of design of removable partial denture （RPD）. Methods    Sixty students who underwent standardized training in prosthodontics in China Medical University Hospital of Stomatology from September 2020 to September 2022 were selected for the study. All students received software training and learned related courses in advance，after which they completed the tests of 20 cases of traditional RPD design tests（traditional group），20 cases of RPD design online（digital group），and an anonymous questionnaire survey. Results    The scores of the students′    tests were 76.5 ± 6.1（traditional group）and 80.0 ± 8.0（digital group）respectively，and there was no significant difference（t = -2.685，P = 0.510）. The results of the questionnaire showed that 95.0%（57/60）of the students believed that the understanding of RPD design was improved through the digital methods；98.3%（59/60）of the students expressed their interest in the RPD design software and believed that the use of the software improved their interest and motivation in learning；100%（60/60）of the students indicated that the software was easy to operate and helpful in learning RPD design，which would help in the teacher-student communication and said that they would use the software in the future. Conclusion    Digital technology in the teaching of RPD design can promote the understanding of design of RPD，and improve learning interest，initiative and the communication between students and teachers.

摘要： 目的    评价数字化技术在口腔修复可摘局部义齿设计教学中的应用效果。方法    选择2020年9月至2022年9月在中国医科大学附属口腔医院行口腔修复住院医师规范化培训的60名学生为研究对象。所有学生均按照教学方法接受数字化软件培训和相关课程学习，学习后分别完成20例传统可摘局部义齿设计试题（记为传统组）、20例数字化软件可摘局部义齿设计试题（记为数字化组）及匿名问卷调查。结果    传统组试题评分为（76.5 ± 6.1）分，与数字化组［（80.0 ± 8.0）分］比较，差异无统计学意义（t = -2.685，P = 0.510）。调查问卷结果显示：95.0%（57/60）的学生认为通过数字化教学方法的学习提高了对可摘局部义齿设计的理解；98.3%（59/60）的学生表示对可摘局部义齿设计软件感兴趣，并认为使用该软件提高了学习的兴趣和主动性；100%（60/60）的学生表示数字化软件容易操作，对可摘局部义齿设计教学有帮助，有助于在教学上的师生沟通并表示在以后的工作学习中会使用该软件。结论    数字化技术应用于可摘局部义齿设计教学中能够帮助学生更好地理解可摘局部义齿的设计，提高学习兴趣、主动性和师生沟通效率。
