The first implants made of Russian biopolymers have been created in Russia

The Center for Engineering Development (CIR) of the First Sechenov Moscow State Medical University has created implants for reconstructive and plastic surgery in the maxillofacial region made entirely of Russian medical polymers. Previously, there were no domestic medical polymers on the market.

At the request of clinicians, the designers designed a 3D model of an implant for mandibular surgery based on a CT scan of a real patient. At the same time, domestic software was used. Then, several samples of medical products were made on a 3D printer and injection molding machine, using two different biocompatible polymer materials — polysulfone and polyesteresterketone. They were synthesized at the Center for Advanced Materials and Additive Technologies of Kabardino-Balkarian State University.

"For the manufacture of implants, we used Russian polymers, which were not previously available on the market. To date, there are no foreign polymers of decent quality on the market for medical use," said Alexander Kulish, Director of Technology Commercialization at the First Moscow State Medical University.

He stressed that unlike metal implants, the developed biopolymer is 40% lighter than titanium, in addition, it does not cause allergies, and its characteristics are close to human bone, which makes its use more comfortable for humans. The expert also added that such an implant is not subject to corrosion and hydrolysis, is highly resistant to degradation in the biological environment, is capable of sterilization by any method, and is fully biocompatible and safe at the cellular and genetic levels.

Currently, medical devices are being tested at the university's clinical center to obtain a registration certificate.
