CAD-CAM Fixed Dental Prostheses (FDPs)

Abstract

Fixed dental prostheses are a common and predictable option for the replacement of missing teeth. These restorations require the preparation of the abutment teeth in order to allow adequate space for the materials used to fabricate the prosthesis. Once the preparation is completed, the three-dimensional information relative to the oral hard and soft tissues is captured through a digital or an analog impression to allow the design and fabrication of the prosthesis using CAD-CAM technology. Clinical evidence has shown the predictable long-term survival of fixed dental prostheses, which varies depending on the length of the edentulous span, the abutment status, and prosthetic materials.
