A new material for highly biocompatible implants is being developed in St. Petersburg. The project involves specialists from Peter the Great St. Petersburg Polytechnic University (SPbPU), St. Petersburg State Technological Institute, and the V. A. Almazov National Medical Research Center. This was reported by the press service of the Ministry of Education and Science of Russia.
Scientists are looking for the ideal composition of a biocompatible and durable polymer-thermoset for endoprosthetics. Such materials will significantly speed up and reduce the cost of prosthesis manufacturing: the composition can be mixed and the implant can be made directly near the operating table.
Researchers tested thermoplastic polymers using high-temperature exposure, infrared spectroscopy, and X-ray diffraction. Special attention was paid to the interaction of samples with liquids.
This allowed us to measure the pores that appeared in the material as a result of 3D printing, as well as identify the rheological behavior of the materials under study. The implementation of an open porous structure in the future will ensure osseointegration, that is, the "ingrowth" of bone into the implant.
Currently, the most common material for prostheses and implants is titanium alloy. However, such implants do not take into account the individual characteristics of patients.
Scientists plan to determine the composition of the new polymer and begin testing it in the laboratory for future replacement of titanium.
Earlier www1.ru reported that Roscosmos' "daughter" increased the production of robotic knee prostheses by 30%.
