Abstract: Objective　 To evaluate the application effect of case-based learning assisted by digitization in clinical teaching of oral and cranio-maxillofacial deformities. Methods　A total of 40 students from College of Stomatology， Shanghai Jiao Tong University School of Medicine were randomly divided into control group （n=20） and experimental group （n=20）. Students in control group received traditional teaching method with theoretical lectures， while students in experimental group received CBL assisted by digitization teaching method on the basis of traditional theoretical lectures. Theoretical knowledge， practical comprehensive ability assessment scores， and questionnaire survey of two teaching methods were evaluated. Results　 In terms of theoretical scores and clinical practice assessments， the experimental group performed significantly better than the control group， with a statistically significant difference（ P<0.05）. The students' experience ratings in control group and experimental group were 6.1±0.64 and 8.5±0.76， respectively， with a statistically significant difference（ P<0.05）. Questionnaire surveys showed that CBL assisted by digitization teaching method had received more positive feedback from students in terms of lively， interesting， and satisfactory courses， compared to traditional teaching method. Conclusion　The  application of CBL assisted by digitization teaching method is helpful to improve students' mastery of theoretical knowledge and increase their learning interest， and is an effective teaching method for improving and enhancing the practical application of oral clinical teaching.
