Background:, Prosthodontic Rehabilitation for trismuspatients with extremelyrestricted mouth openings by using traditional methods represent a big challenge for prosthodontists. Intra oral scanning and digitalized three dimensional CAD,CAM technology have affordeddifferenttechniquesused in the construction of highly accurate virtual dentition casts. Aim: to improve the accuracy of aRPD framework by incorporating the digitalization technology, computer-aided design (CAD), and 3D printing. Materials and Methods: Multiple intraoral scans were used to reconstruct the virtual cast on which the authors planned the virtual RPD framework. Thenusing a 3D printing process, the titanium alloy framework was constructed, and the final RPD was fitted on the patient mouth. Conclusions: Digitalization technology, computer-aided design (CAD), and 3D printing andIntraoral scanning provided an accurate and effective method in the construction of a removable prosthesis for a trismus patient with severly restricted mouth opening.
