Abstract: Digital sensing technology includes virtual reality，augmented reality and mixed reality technology. It′s a major breakthrough of image technology in this new era. These techniques using digital methods to capture，regenerate or synthesize various sensory inputs from outside signify the coming of an age of new digital technology of 3D graphic simulation and scene reproduction. We have witnessed the increasing application of these new techniques in clinical practice and in biomedical engineering. Globally，to enhance the teaching experiences and management of medical students（including bachelors，postgraduates and residents），there exists a trend of trying to add these novel technological elements to the medical teaching practice and management of oral and maxillofacial surgery（inclucing craniofacial and head and neck surgery）. Although we are currently at the forefront of using these digital sensing techniques in clinical practice，the application in the teaching of oral and maxillofacial surgery falls behind. Therefore，a better understanding of the history and current status of using virtual reality，augmented reality and mixed reality technology in teaching helps fill up a lacuna in our teaching. And at the same time，it can promote the wide application of digital sensing technology in the teaching of oral and maxillofacial surgery. In this article，we not only reviewed the development and application of digital sensing techniques in the teaching of oral and maxillofacial surgery，but also explored their application in the teaching of oral and maxillofacial surgery in the School of Stomatology，Shanghai Jiao Tong University，with an aim of providing reference for the teaching of oral and maxillofacial surgery.

Key words: virtual reality, augmented reality, mixed reality, teaching of oral and maxillofacial surgery
