In recent years, with the in-depth application of digital technology in the whole process of oral functional rehabilitation, its value in aesthetic cosmetology has become increasingly prominent. At present, the common digital technologies in the ffeld of oral rehabilitation mainly include three-dimensional data acquisition technology, computer-aided design and computer-aided manufacturing (CAD/CAM) technology in stomatology, and digital technology for oral surgery implementation. This paper systematically sorts out the technical principles and characteristics of different types of digital technologies for oral rehabilitation, analyzes the application characteristics and current status of various technologies in oral functional rehabilitation and aesthetic rehabilitation, and combined with the development trend of technologies, points out that the in-depth integration of different digital technologies, the improvement of intelligence and the continuous expansion of application scenarios are the core directions in the future, so as to better promote the optimization of clinical practice of digital oral rehabilitation and provide theoretical reference for the development of subsequent related researches.
