Abstract: PURPOSE: To explore the teaching application value of multi-dimensional digital technology in cultivation of postgraduates of oral and maxillofacial surgery (OMS). METHODS: A total of 30 patients with maxillofacial fractures and dental-maxillofacial deformities were selected. The complete medical history, medical records, imaging data, dental-maxillofacial 3D printing models and photographic data were collected to form a multi-dimensional digital database. A total of 26 postgraduates of School of Stomatology, Fujian Medical University who have been trained in OMS department since 2019 were randomly divided into experimental group and control group, with 13 students in each group. The control group adopted traditional teaching mode, while the experimental group was trained with multi-dimensional digital technology. After teaching courses, the students were assessed in both lectures and skills, and the learning effect was evaluated by questionnaire survey. SPSS 19.0 software package was used for data analysis. RESULTS: The scores of the experimental group were (81.42±3.31) and the control group were (74.29±3.21). The questionnaire score of the experimental group was (25.08±0.30) and that of the control group was (19.29±0.53). The difference was statistically significant (P<0.05). CONCLUSIONS: Multi-dimensional digital technology can play a good teaching auxiliary role, help students deepen their understanding of anatomy, surgical methods and surgical design, stimulate learning enthusiasm and innovativeness, and is worthy of wide application in clinical teaching of oral and maxillofacial surgery.
