Carbon compounds are involved in the formation of all human body tissues (around 70% of the human muscle mass and 40% of the bone tissue consist of carbon), which ensures its high biocompatibility.
Carbon materials do not dissolve in organic and inorganic solvents, and do not react with alkalis, acids, salts, organic and biologically active compounds.
The surface of materials produced from pure carbon actively adsorbs and retains biologically active compounds and living cells.
Carbon materials are as resistant to corrosion as products manufactured from precious metals – gold and platinum.
This ensures that the mass of the carbon implant corresponds to the mass of the bone defect replaced, and causes no additional inertia loads in the bone-implant system.
This increases the attraction between protein structures or living cells and the surface of the carbon material, and makes it possible to use it during electrotherapy
- open porosity – not less than 5%;
- compressive strength – not less than 30 MPa;
- bending strength – not less than 20 MPa;
- elastic modulus for compression – not less than 1.5 GPa.
Carbon nanostructured implants can be used for patients of all ages; they are not recommended for children younger than 1 year of age and patients over 80 years of age. No limitations are set for patients with various body weights and anthropometric measurements.
