Abstract: Maxillary defect is the most common type of oral and maxillofacial defect, while the traditional method to make prostheses by molding and hand processing is complicated and the effect is unsatisfying. Digital technology serves a new way of rehabilitation of maxillary defects. The research of different scholars has proposed different digital implementation methods, which have greatly improved the production process and clinical effect of the prostheses. Digital technology has become one of the most important development directions for rehabilitation of maxillary defects. In this study, we used Wanfang Data Platform and PubMed database to retrieve articles on digital prosthesis for maxillary defects, including digital model acquisition, three-dimensional design of the prostheses, digital fabrication of the prostheses and digital implant-assisted rehabilitation for maxillary defects. The contents included the joint application of various new technologies and new design concepts, as well as the clinical attempt to make prostheses using new materials. With a multidisciplinary approach, the comprehensive concept of shape and function reconstruction promises a new development direction for digital rehabilitation of maxillary defects.

Key words: maxillary defect, prostheses, obturator, intraoral scanning, three-dimensional printing
