Abstract:

With the rapid development of digital technology in stomatology, it has been increasingly applied in all aspects of complete denture restoration. With computer aided design and computer aided manufacturing (CAD/CAM) as the core, digital technology integrating intraoral scanning, face scanning, 3D printing and computer numerical control cutting has brought great changes to the restoration process of full dentures. This paper discusses the attention and experience of the application of digital technology in complete denture restoration from five main links: the preliminary digital model of edentulous jaw, the record of preliminary law relationship, the design and production of individual tray complex, the master digital model of edentulous jaw and the acquisition of final jaw relationship, and the digital production of complete denture. Compared to traditional models that rely on experience and manual operation, digital technology has been able to improve the accuracy, predictability and efficiency of complete denture restoration, while reducing the number of visits and improving patient comfort and experience. However, the whole-process digitalization of complete denture restoration has not been realized at present, and the cross-fusion and clinical application of digital technology and complete denture restoration still face many problems that need to be standardized and further studied.

Key words: complete denture, digital technology, in-traoral scanning, 3D printing, numerical control cutting
