Abstract :Hybrid prostheses, which are among the implant-supported fixed prostheses, are defined as screw-retained restorations produced from different materials. These prostheses reconstruct the dental hard tissues together with the lost gums and surrounding tissues. Hybrid prostheses can be prepared from metal substructures produced from chromium-cobalt (Co-Cr) alloy, millable zirconia and polyetheretherketone (PEEK). Co-Cr metal substructures can be obtained by traditional casting, selective laser sintering and computer-aided manufacturing/computer-aided design (CAD/CAM) methods. Substructures such as zirconia and PEEK are generally produced with CAD/CAM. Substructures produced with the CAD/CAM method have advantages such as high precision adaptation to supports, slightly longer cantilever length, elimination of errors that may occur due to the technician, and elimination of the risk of shrinkage in the metal during casting. In hybrid prostheses, various materials such as metal ceramics, all-ceramic materials, acrylic resins, and thermoplastic polymer PEEK are used for the superstructure production. Dental ceramics to be used as the superstructure can be traditional feldspathic or can be obtained from all-ceramic systems such as monolithic zirconia produced by CAD/CAM method. With the developments in material structure, monolithic zirconium hybrid prostheses cemented to titanium bars produced by CAD/CAM method have begun to be produced. The computerized workflow of this digitalized production process provides reproducible results and excellent adaptation and passive placement of the bars. This literature review aims to provide an up-to-date overview of the materials used in hybrid prosthesis production and to evaluate the clinical benefits and limitations of these materials and techniques.
