A unique ceramic material based on zirconium and aluminum oxides modifed with nanocomponents has been developed.The ceramics has superior characteristics, namely:
• its strength is 3–5 times higher than the strength of any known ceramics (σbend ranges from 800–1200 to 1800 MPa);
• the friction coeffcient is reduced by a factor of 8 to 12 as compared to the friction coeffcient of metals commonly used in medicine;
• improved biocompatibility and chemical resistance in the human organism than those offered by other materials.
The developed high-strength nanoceramics allows endoprostheses and implants of the new generation to be manufactured that can be used in orthopedics, stomatology, and endoprosthesis as replacements of heavily loaded segments in the human body, which run high risk and are prone to wear (the vertebral column and joints, including hip joints, etc.). The large-pore bioactive ceramics ensure long-time fxation of endoprostheses and implants in the human body and will serve as a universal material for restoration of the bone tissue in all surgical operations in orthopedics, traumatology, otolaryngology and stomatology during the treatment of parodontosis, bone defects, cysts, and tumors.
The major advantage of the proposed ceramics is the possibility to obtain medical devices with the service life several times higher than that of the existing products, including imported devices. The competitive production of the nanoceramic implants and endoprostheses in Russia will be able to fully meet the demand for such products, considerably reducing production costs, thus avoiding the dependence on the imports.
