TOMSK, Nov 23 – RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU) developed implants on the basis of polymers which are completely dissolved in an organism in a certain time; with their help doctors will be able to operate the heaviest injuries of face and head and to restore a bone tissue of a cancer patient, the press service of the HEI reports.
"It is hybrid products, the metal gauze modified by plasma methods which grows into a bone over time is in their basis. The grid is covered with composite material on the basis of biodegraded polymers and calcium - phosphate fillers", – the head of the research team Sergey Tverdokhlebov is quoted in the message.
It is noted in TPU that the implant basis (the grid) is modified in such a way that metal in an organism doesn't rust and gains bioactive properties. And fillers from calcium and phosphorus of a polymeric composite "camouflage" an implant at a bone tissue, and the organism doesn't perceive it as a foreign matter. So survival of the implant increases.
According to Tverdokhlebov, there are no analogs of Tomsk implants in Russia. Now the first prototypes successfully pass medical tests in Tomsk scientific research institute of oncology. "The first prototypes represent plates of 40 by 40 millimeters in size. In practice they can close, for example, openings in a skull", – the scientist noted.
After completion of tests Tomsk products can come to production. "Our main industrial partner at this project is the Moscow Company JSC Konmet. The company is the leader at the Russian market in production of implants for maxillofacial surgery. And after tests in Tomsk the Company can make the decision on a production of the implants", – Tverdokhlebov summarized.
