Abstract: Described herein is a system for hybrid denture fabrication. The system improve the efficiency of the fabrication process for both the dental service provider (e.g., dentist, dental surgeon, etc.) and the patient. A permanent hybrid prosthesis (e.g., the bridge and its reinforcing bar) can be fabricated within 24 hours of the surgical procedure using the system described herein. This makes it possible to deliverer the permanent hybrid prosthesis within 48 hours (or even within 24 hours) of the surgical procedure. Additionally, the system eliminates the need to provide the patient with a temporary denture following the surgery. Further, the system substantially reduces the patient's chair-time and/or the number of patient visits.
