TOMSK, Mar 23 – RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU)
plan to create until the end of 2016 prototypes of implants for face and skull
on the basis of biodegradable polymers, which can be applied to treatment of
people, the project manager, the associate professor of experimental physics
Sergey Tverdokhlebov has reported RIA Tomsk.
Earlier it was reported that by means of these implants doctors will be
able to operate the heaviest injuries of face and head and to restore bone
tissue of a patient with cancer. An implant basis is the grid, modified so that
metal in an organism don't rust and gained bioactive properties. Fillers from calcium
and phosphorus of a polymeric composite "mask" an implant under a
bone tissue, and an organism doesn't tear away it.
"Now we have prototypes, which pass tests on animals and in test
tubes. According to the planned schedule, by the end of the year we plan to
create an implant, which will be suitable for clinical trials", –
Tverdokhlebov told.

He has specified that the project is carried out within the federal target
program (research financing – 45 million rubles). Now for production of
implants scientists use modern technologies: "fittings" of a
framework are cut out from the titan by means of the laser, and the polymeric
part is printed on the 3D-printer.
According to the scientist, now implants have no domestic analogs. There
are similar developments abroad, however their filler is not biodegradable
materials, but porous polyethylene, which isn't "dissolved" in an
organism. Also these implants, unlike Tomsk, don't pass the "masking"
processing, it means they get accustomed worse in an organism.
Tverdokhlebov has added that so far the task for the scientists includes
only development of effective "patches". Clinical tests are too
expensive, but they can be carried out by the Tomsk scientific research
institute of oncology, which is a collaborator of the project can. The
researches are also supported by the technological platform "Future
Medicine", the industrial partner is the Moscow firm OOO Konmet.
