case_images: A 23-year-old male presented to the dental clinics at King Saud bin Abdulaziz University, Riyadh, Saudi Arabia, with a primary concern of restoring his teeth, improving his speech, and restoring his function (Figure 1(a)). The shape of the residual alveolar ridges was square in the maxillary arch and U-shaped in the mandibular arch (Figure 1(b)). Radiographic examination revealed no abnormalities other than severely resorbed maxillary and mandibular alveolar ridges (Figure 1(c)).

case_images: The preliminary diagnostic casts were scanned using an intraoral scanner (TRIOS; 3Shape) and imported into a computer-aided design and computer-aided manufacturing software program (DentalCAD  3.1, Rijeka) where record bases were fabricated and 3D printed using a PMMA resin material (Freeprint matrix; Detax, GmbH Carl-Zeiss-Str.4) (Figures 3(a)-3(c)).

case_images: This file was then used to digitally set up and design a denture prototype, which was 3-dimensionally printed using a PMMA resin (Freeprint matrix; TRYIN, GmbH) (Figure 5). Once the modifications had been completed, a wash impression with polyvinyl siloxane (Imprint 4; 3M ESPE) was made since the prototype denture base was underextended (Figures 5(a)-5(c)).
