AB  - PURPOSE: This study comprehensively reviewed the current status of the digital 
      workflow of removable partial dentures (RPDs) and summarized information about 
      the fabrication methods and material properties of the dental framework, 
      artificial teeth, and denture base. STUDY SELECTION: We performed a systematic 
      review of the literature published in online databases from January 1980 to April 
      2020 regarding RPD fabrication and materials used in the related digital 
      technology. We selected eligible articles, retrieved information regarding 
      digital RPDs, and conducted qualitative/quantitative analyses. In this paper, the 
      computer-aided design/computer-aided manufacturing (CAD/CAM) framework, 
      artificial teeth, and denture base materials are reported. RESULTS: A variety of 
      materials, such as cobalt-chromium alloy, titanium, zirconia, and polyether ether 
      ketone, are used for dental CAD/CAM frameworks. The mechanical strength of the 
      metal materials used for the CAD/CAM framework was superior to that of the cast 
      framework. However, the fitness and surface roughness of the framework and clasp 
      fabricated using a selective laser melting (SLM) method were not superior to 
      those obtained via cast fabrication. Most material properties and the surface 
      roughness of poly methyl methacrylate (PMMA) discs used for digital RPDs were 
      superior to those of heat-cured PMMA. CONCLUSION: The use of a CAD/CAM framework 
      and PMMA disc for digital RPDs offers numerous advantages over conventional RPDs. 
      However, technical challenges regarding the accuracy and durability of adhesion 
      between the framework and denture base remain to be solved. In digital 
      fabrication, human technical factors influence the quality of the framework.
