Ceramic Biomaterial Applications

Wilson editors 1990 crc handbook of bioactive ceramics vol ii 4.

Ceramic biomaterial applications. Materials for hard tissue applications. The word biomaterial itself is loosely employed for describing a wide variety of materials used for biomedical applications. J amer ceramsoc 1991 74 7 1487 510. In bone repair applications i e.

Joint tissue replacement metal coating to improve biocompatibility. Ceramics are refractory polycrystalline compounds usually inorganic including silicates metallic oxides carbides and various refractory hydrides sulfides and selenides. Biological assessment of bioceramics. Ceramic biomaterials have been widely used in biological applications as orthopaedic and dental implants and porous scaffolds for tissue engineering.

Issues and perspectives 5. And ceramic coatings on metallic implants degrade over time during lengthy applications. Ceramics provides current information on ceramics and their conversion from base materials to medical devices. Assessment of mechanical properties of ceramic materials 4.

Bioactive ceramics including bioglasses must be non toxic and form a bond with bone. Bioinert ceramics such as alumina and zirconia have excellent mechanical properties for load bearing applications while bioactive glasses and ceramics have the potential for osteoconduction. They do not create strong biologically relevant interfaces with bones but they do promote strong adhesions to bones 3 the main applications of ceramic biomaterials include. Bioceramics on the market.

Ceramic biomaterials vol 1 2. A review of classes of biomaterials and their applications is presented. From concept to clinic. Particular interest is paid to bioceramics calcium phosphates and.

Arguments still arise on where exactly the boundary lies between an authentic biomaterial and a biomedical device. Scaffolds for bone regeneration the solubility of bioceramics is an important parameter and the slow dissolution rate of most bioceramics relative to bone growth rates remains a challenge in their remedial usage. Ceramic biomaterials also stimulate bone growth and have low friction coefficients. Ceramics for joint replacement.
