Peter the GreatSt. St. Petersburg Polytechnic University (SPbPU) is working on the creation of implants for bone tissue restoration, including cranioplasty (a procedure to restore skull bones). Nurjemal Tagandurdyeva, employee of the Institute of Biomedical Systems and Biotechnology at St. Petersburg Polytechnic University, told socialbites.ca.
“In adults, the defect is usually replaced with non-absorbable materials such as titanium or polymers. But it is impossible to use such materials in children’s plastic surgery, since the child’s body grows and the listed materials are insoluble. Therefore, the bone tissue will dissolve as it grows, we need resorbable materials. I am currently interested in the creation of such composite materials ” said the expert.
According to Tagandurdyeva, such implants need to be durable but also absorbable. Such properties can be achieved by producing composites, that is, by combining two components (a filler in the form of chitosan fabric and a matrix based on polylactide or polycaprolactone).
“The strength of such composites is comparable to the strength of bone tissue. Bone tissue continues to bear the load and heal, and our material is absorbed over time and replaced by natural bone tissue,” explained the biophysicist.
Scientists are now conducting tests on small laboratory animals.
