In recent years, with the in-depth application of digital technology in the whole process of oral functional restoration, its value in aesthetic restoration has become increasingly prominent. The commonly used digital technologies in the field of prosthodontics at present mainly include three-dimensional data acquisition technology, computer-aided design and computer-aided manufacturing (CAD/CAM) technology in stomatology, and digital implementation technology of oral surgery. This paper combs the technical principles and characteristics of different types of digital technologies applied in prosthodontics, analyzes their application characteristics and current application status in oral functional restoration and aesthetic restoration. Combined with the technological development trend, it points out that the in-depth integration of different digital technologies, the improvement of intelligent level and the continuous expansion of application scenarios are the core development directions in the future, so as to better promote the optimization of clinical practice of digital prosthodontics and provide a theoretical reference for the development of subsequent relevant research.
