MOSCOW, June 22 -. RIA Novosti The team of scientists of the Siberian federal University (SFU) in Krasnoyarsk is working to create bone structures from biocompatible materials, taking into account the individual characteristics of the patients, told RIA Novosti press-service of the university <. / p>

it is assumed that the bone structures derived from polyhydroxybutyrate (fully biodegradable material, synthesized by microorganisms) using 3-D prototyping and computer tomography, to be used in high-tech treatments.

Getting the synthetic bone of biocompatible materials based on individual anatomical and morphological and functional characteristics of the patients in the near future will be the “gold standard” of orthopedics and avoid the use of foreign materials to treat disease, told RIA Novosti Head of the Department of medical Biology SFU professor Catherine Shishatskaya.

” The additive prototyping allows to obtain products of almost any shape and size. Given that the modern equipment allows you to take pictures with up to 0,625 mm, and software systems – to isolate the types of tissues, individual objects and store the data in the form of models, the method is ideal for the manufacture of the piece, the individual structures. It is only necessary technology for processing the biopolymer material for printing “, – she said

According to scientists, but to use the computer a patient imaging data model for printing can be obtained by focusing on the average statistical data about the size of a bone in particular. age and growth group.

When you print using layer-fusing material, which is capable of applying the polymer without changing the chemical structure and the use of adhesive, said member of the scientific team, winner of the International youth innovation forum “Lomonosov”, student of the Institute of basic Biology SFU and biotechnology Konstantin Kistersky.

“rod with reel on the Teflon tube is held in miniekstrudera nozzle and prints a layer of a given thickness, moving along the X and Y-axis in this platform, giving a new layer for printing, shifted axis Z. produced by different printing technologies for the needs rod 1.75 mm in diameter. Currently, we are trying different approaches, based on the physical and mechanical properties of the polymer material “Bioplastotan”, – he said

“Bioplastotan.” – Biodegradable polymer created Krasnoyarsk biologists. In 2010, for his research on the development of technologies for “Bioplastotan” and for the creation of scientific bases for their application in medical practice Ekaterina Shishatskaya was awarded the RF Presidential Award.

In the next step of the scientists are going to conduct a comprehensive evaluation of the experimental implants compliance with Russian and international standards for implantable medical devices intended for long-term and constant use and have a high individual risk.
