MEDICAL AND DENTAL materials are in the class of materials called biomaterials. Biomaterials are used in the body to replace body components or assist in retaining or restoring body functions. Biomaterials include synthetic materials, modified natural materials, biosynthetic materials, systems engineered materials, and morphological protein molecules that can send signals of direction to cells [1]. Synthetic biomaterials may be metallic, ceramic, polymeric, or a combination of these as needed to meet the needs of intended application.
