ABSTRACT
The basic concepts in metallic, ceramic, and polymer-based materials used in orthopedic and dental implants are outlined. The knowledge of mechanical properties, uses and limitations of these biomaterials is indispensable in order to improve the performance of current generation implant materials. The tensile strength, modulus, fracture toughness, and fatigue strength of the biomaterials used in load-bearing applications are compared. The friction and wear characteristics, corrosion mechanisms, and their biocompatibility are also presented. Further, the instrumental methods and techniques for structural and physicochemical characterization of biomaterials are described briefly.
