摘　　要：目的:探讨数字化辅助的案例教学法(Case-based learning,CBL)在研究生正畸-正颌外科联合治疗教学中的应用,以提供教学模式新思路。方法:将30名口腔正畸专业一年级研究生随机分为两组,对照组采用PPT讲解知识点配合病例图片展示的传统教学模式,实验组在传统教学模式基础上增加三维数字化辅助的CBL教学,即在常规讲授教学前组织研究生学习三维数字化软件在正畸-正颌外科联合治疗典型病例中的应用。采用随堂测验和问卷调查法对学生知识点掌握情况和教学满意度进行综合评价。结果:随堂测验中,对照组得分为(9.87±1.71)分,实验组得分为(11.40±1.99)分,实验组对知识点的掌握情况显著优于对照组(P<0.05)。两组学生在课前对此次课程的期待程度比较,差异无统计学意义(P>0.05),课程满意度综合评价中,实验组得分均显著高于对照组(P<0.05)。结论:将三维数字化辅助的CBL教学模式应用于研究生正畸-正颌外科联合治疗教学,更能激发学生的学习兴趣,有助于学生在课堂上注意力的集中,使得教学内容更加容易理解,值得在正畸研究生教学中推广。Objective To explore the application of digitally assisted CBL in the teaching of combined orthodontics and orthognathic surgical treatment for postgraduate students,so as to provide new ideas for the teaching model.Methods 30 first-year postgraduates majoring in orthodontics were randomly divided into two groups.In the control group,the traditional teaching mode of PPT with case pictures was used to explain the knowledge points.In the experimental group,digitally assisted CBL teaching was added to the traditional teaching mode,and the postgraduate students were organized to learn the application of 3D digital software in typical cases of combined orthodontic-orthognathic surgical treatment before the conventional lecture teaching.The students'knowledge and satisfaction of teaching were evaluated by means of a follow-up quiz and questionnaire.Results In the follow-up test,the score of the control group was(9.87±1.71)points,and the score of the experimental group was(11.40±1.99)points.The mastery of knowledge points in the experimental group was significantly better than that of the control group(P<0.05).There was no significant difference between the two groups in terms of students'expectations of this course before class(P>0.05).In the comprehensive evaluation of course satisfaction,the scores of the experimental group were significantly higher than those of the control group(P<0.05).Conclusion The application of digitally assisted CBL in the teaching of combined orthodontics and orthognathic surgical treatment for postgraduate students can better stimulate students'interest in learning,help them concentrate in class,and make the teaching content easier to be understood,which is worth promoting in orthodontic postgraduate teaching.
