Abstract

This article provides proof of concept for the use of intraoral scanning technology to record hard and soft tissue morphology for the fabrication of a cast partial removable dental prosthesis. An open source intraoral scanner was used to scan the hard and soft tissues to create a stereolithographic file that was subsequently imported into a computer-aided design software program for the digital/virtual design of a partial removable dental prosthesis framework. Computer-aided design and computer-aided manufacturing technology was then used to fabricate a resin framework that was trial placed to evaluate accuracy and for conventional investing and casting with a cobalt-chromium alloy. The cast framework and definitive prosthesis were judged to be clinically accurate in fit, stability, and retention.
