Abstract: Digital technology has become pervasive in dentistry. In the face of the aging population, the research on digital complete denture restoration has been highly popular. Compared with the traditional complete denture restoration, the digital complete denture brings patients a more comfortable treatment experience and a shorter treatment period. This article briefly describes the latest research progress of digital complete dentures from the aspects of digital impression, CAM technology, material properties and clinical effect evaluation, in order to provide a reference for clinicians and help improve the efficiency and effectiveness of diagnosis and treatment.
