Short description of the project

The project aims to create competitive modern bioactive materials for medical purposes and sorption materials for personal protective equipment and household air conditioning systems based on modified calcium hydroxyapatite.

The most significant results achieved

New compositions based on calcium hydroxyapatite were created. They can be used for: treatment of periodontitis with destruction of bone structures; management of acute deep caries of teeth; compaction of dentin in deep caries; elimination of the consequences of traumatic tooth extraction; stopping the processes of bone resorption in the periapical area of the tops of the roots of periodontal teeth; remodeling of destroyed bone during the treatment of chronic periodontitis; stimulation of the vascular-nervous bundle during the treatment of deep dentin lesions in a closed tooth cavity; permanent filling of root canals during destructive periodontitis in molars; treatment of destructive periodontitis; helping patients with diabetes to prevent complications from traumatic tooth extraction.

Effective sorbents are created that can be used as surface coatings and components in protective agents capable of absorbing viruses, microbes and toxic substances.


Application areas

Medicine and health care (ceramic implants, sorbents for personal protective equipment, coatings and components of respirators capable of absorbing viruses, microbes and toxic substances), ecology (sorption materials)
