PHYSICAL-PROPERTIES OF MATERIALS IN MEDIC INE

Metallic, ceramic, and polymeric materials are applied in all discipli nes of surgical and dental medicine. The biocompatibility is determine d by the chemical composition, the mechanical and electronic structure s of the material's surface, the properties of the interface to the sp ecific body electrolyte as well as by reactions, which occur between t he solid and the liquid phase. The development of biomaterials, consid ering the sensitive biological environment, requires knowledge from al l fields of the natural sciences and knowledge of manufacturing method s derived from the key technologies.
