OSTEO-CONDUCTIVE COATINGS FOR IMPLANTS

08.09.2020

PURPOSE:

An original method has been developed for producing osteoconductive coatings for medical implants based on hydroxyapatite, which is the main component of bone tissue.

DESCRIPTION:

The method consists in applying low-temperature (up to 100 ° С) coatings based on hydroxyapatite and biopolymers to the surface of implants of various shapes using external electromagnetic fields.

ADVANTAGES:

Compared with traditional methods for producing coatings (vacuum technology, plasma and thermal spraying, electrophoresis, sol-gel gel deposition, application by laser radiation), the proposed method has the following advantages:

- - - the method is suitable for deposition on metal implants of various shapes and compositions;
    - direct deposition of hydroxyapatite on the surface of substrates from aqueous solutions;
      rapid precipitation (from 10 to 60 min);
    - the possibility of obtaining composite coatings based on biopolymers and/or drugs and hydroxyapatite, which makes it possible to approximate the resulting material in bone tissue;
    - coatings have a controlled phase composition, porosity and morphology.

RESULTS OF THE RESEARCH:

Provides consistent results.

STAGE OF THE DEVELOPMENT READINESS:

Prototype manufactured.
