With the development of digital medicine,digital technology is becoming increasingly popular in various fields of dentistry. The continuous iteration of digital dental devices has attracted great attention to dental digitization. The digital process mainly consists of three steps,the first step is to obtain data with the help of scanners,the second step is to select software for data processing and diagnosis and treatment plan design,and the third step is to process materials with the help of equipment. The review focuses on data acquisition technology,computer aided design technology,computer aided manufacturing technology and surgica implementation technology,briefly introduces oral digital materials,and looks forward to the future of oral diagnosis and treatment,hoping to follow the development of the traditional diagnosis and treatment model and provide references for clinical and scientific research.
