Abstract

This case report applies computer-aided design and computer-aided design manufacturing (CAD/CAM) technology in fabricating an implant-retained monolithic overdenture for a patient with limited vertical restorative space. Traditionally, a vertical space of 9 to 12 mm is required for conventional overdentures; however, this patient presented with only 6 mm available. Through the integration of CAD/CAM, a novel solution was designed that optimized both function and esthetics within the constrained space.
