A systematic review of digital removable partial dentures

Abstract

We performed a systematic review of the literature to comprehensively review the current status of digital workflow and the challenge in fabricating removable partial dentures. In 2019, RPDs can be fabricated with a fully digital workflow without a definitive cast. However, the indication for full-digital RPD is limited for cases with Kennedy Class III/IV partially edentulous arches with few missing teeth. Intra oral scanners were used for digital impression taking and maxillomandibular relationship recording. CAD/CAM framework fabricated using selective laser melting is commercially available in Japan. Future challenges for improvement in accuracy of intra oral scanners, accuracy and durability of connections between the framework and denture base, and for reduction of fabrication cost remain to be solved in digital removable partial dentures.
