Abstract B a c k g r o u n d This article describes a technique of the creation of a virtual wax-up and design of a wax prototype used as a pattern for the fabrication of poste- rior metal–ceramic and anterior pressed lithium disilicate restorations for a patient with a severely worn dentition. M a t e r i a l s a n d m e t h o d s During the rehabilitation of a patient, computer-aided design (CAD) can be used as a tool to verify marginal adaptation, occlusion and contact points before pressing or fabricating the final restorations. The proto- types work as an esthetic try-in that can be modified easily if necessary. R e s u l t s After proper verification, there were no marginal discrepancies and no occlusal modification was required, nor were contact points adjusted during final delivery. After a 1-year follow-up, the patient reported no complications. C o n c l u s i o n Computer-aided design/computer-aided manufacturing has brought many advantages to restorative dentistry, including producing predict- able restorations in less time compared with traditional methods of fab- rication. In this comprehensive prosthodontic rehabilitation of a severely worn dentition, the virtual diagnostic wax-up and final restoration CAD took less than 60 min for each procedure. Additionally, the wax prototype is a multipurpose restorative tool, as it serves as both an esthetic and functional try-in device and as a wax pattern for the final restoration.
