The scientists of Tomsk State University jointly with Research Institute of Strength Physics and Material Studies of Siberian Department of the Russian Academy of Science have completed the development of prostheses to replace small finger joints, using a nanoceramic material.
Tomsk, Russia., April 18, 2014 - (PressReleasePoint) -Ceramics is apparently very similar to the natural bone in comparison to metals. The main features of nanoceramic units are that it can be solid, monolithic or perforated. The scientist has created a special perforated structure which is very similar to natural bones, so this material is good enough to replace any bone. The materials are zirconium oxide, aluminum or its alloys. This materials are safety for body in compliance with ISO Register. However perforated structure is only the one ingredient of success.
Human body can reject some materials subject to individual particulars. Non-natural bones begins to decompose instead of attaching. So it is very important to provide the ceramic with special properties for better implanting to human body. Special coatings are developed for prostheses to cover perforated structure. Different factors depends upon the composition of coating. For example, ceramic bone can be wettable by one liquid and non-wettable by another, reacted to one medication and inactive to another. Then ceramic surface is seeded with cells for the further monitoring. If cells have produced a calcium-phosphate formations, so such material can replace natural bones. Moreover, prostheses made of domestic nanoceramics will be much less expensive and more affordable to all populations.
This technology can be extensively used in medicine. At the moment, the partners are gearing up for a series of clinical trials which may pave the way for obtaining a license and setting up shop to manufacture nanoceramics-based prostheses. The development of intervertebral prostheses and sample of ceramic jaw have been started.
