摘　　要：目的:以全口义齿个别托盘为例,探讨在口腔医学专业研究生临床实习中应用数字化辅助设计(CAD)的教学效果。方法:选取2019年1月—2019年5月于同济大学附属口腔医院修复科实习的27名研究生作为研究对象,获得知情同意后,进行传统手工方法及数字化方法设计制作个别托盘的理论教学和操作示范,然后分别对其进行操作考核,记录完成个别托盘所需的操作时间,并对托盘边缘延伸位置做出评价。操作完成后填写问卷调查表。采用SPSS 22.0软件包对数据进行统计学分析。结果:CAD在操作时间、托盘边缘位置及学生使用偏好上均显著优于传统手工方法(P<0.05)。结论:CAD有助于学生掌握个别托盘制作的理论知识和数字化操作流程,建议在现有口腔医学教育中加入数字化相关内容。PURPOSE:To evaluate the teaching effect of making custom trays via CAD in dental postgraduates.METHODS:Twenty-seven dental postgraduates from first to third grade at the School&Hospital of Stomatology,Tongji Univer-sity,Shanghai were given an informed consent to explain and request participation in the study.First,a lecture about the theory and process of fabricating custom tray via traditional hand-made method and CAD technique was given,then the students fabricated custom trays via the two methods and completed an online survey.The working time,margin extension and students’preference were analyzed with SPSS 22.0 software package.RESULTS:The working time was shorter,the margin extension was superior,and students’preference was higher via CAD than traditional method,the difference was significant(P<0.05).CONCLUSIONS:CAD is more conducive to enhance students’understanding of custom tray manufacturing process and relevant theoretical knowledge.It is recommended to integrate digital technology into dental curricu-lum.
