| Outline of Final Research Achievements |
The aim of this study was to develop and assess fully digital workflow in a removable partial denture fabrication. A full-arch digital impression and bite registration were made by the intraoral scanner TRIOS2 (3Shape). The 3D images formatted by stereolithography (STL) were imported to CAD software. The connectors, clasps, and artificial teeth were designed by using Dental System D-810 (3shape), and milled from ceria-stabilized zirconia/alumina nanocomposite (Ce/TZP-A; Yamakin), polyetheretherketone (PEEK; Evonik), and hybrid ceramic (VITA ENAMIC; VITA), respectively. The denture base was designed by Freeform (3D Systems) and molded with polymethyl methacrylate (Base; NextDent) by the 3D printer (D30; Rapidshape). Finally, all components were bonded with adhesive material (Super-Bond C&B, Sun Medical).
The patient reported that oral health related quality of life (OHRQoL) and satisfaction of the RPD by fully digital workflow was not very different from that of the conventional RPD.
