Abstract: PURPOSE: To explore the effectiveness of the "one body with two wings" teaching approach in the teaching reform and innovation of oral and maxillofacial surgery. METHODS: An experimental group consisting of 80 undergraduate students of stomatology in 2019 received offline teaching supplemented by newly recorded massive open online courses (MOOCs) and newly written problem based learning(PBL) cases. A score of 90 or more was considered excellent. The teaching results were evaluated by calculating the excellence rate and questionnaire survey.The scores of 79 dental students of grade 2017 who only accepted traditional offline teaching were used as the control group. SPSS 19.0 software package was used for data analysis. RESULTS: The survey results indicated that most students found that the "one body with two wings" teaching approach was beneficial to their learning of professional courses, and that the coherence of course arrangement and content were critical to its effectiveness. The test scores also showed a significant improvement in the excellent rate of the experimental group compared to the control group in the same period(P<0.01). CONCLUSIONS: The "one body with two wings" teaching approach effectively enhances students' interest in learning, academic performance, and provides new ideas for the innovation and development of oral and maxillofacial surgery teaching.
