Digital oral technology is currently the main development direction of oral restoration, which can improve treatment efficiency and enhance the accuracy of dental models. This article focuses on the application of digital oral technology. Firstly, it describes the advantages of digital technology in obtaining oral data, and discusses the methods of obtaining dental models and oral data. The obtained data is statistically analyzed and compared with traditional measurement methods. The comparison results show the advantages of digital oral technology, and further elucidate the application strategies of oral digitization. Then, regarding the teaching issues of oral digital technology, a survey questionnaire was used to explore the advantages and roles of oral digital technology in the classroom, as well as the attitudes of students towards new courses. Based on the current teaching situation, strategies were formulated for teaching application, mainly clarifying the content planning and future development direction of the course, which has good guiding significance for the clinical and teaching implementation of oral digital technology.
