The material’s resistance to biodegradation is determined by the chemical composition of the material, "Ftoraks contains fluorine, the element which has an antibacterial effect. As shown previously, the distribution of fluorine in this material is uneven. In those parts of the surface, where is recorded the presence of fluoride, there is no adhesion ofmicroorganisms and therefore its destruction (10). Silicone is composed of the organosilicon compounds, and, apparently, those organic components included in it, are not destroyed by enzymes, acids or alkalis produced by bacteria.silicon carbidebiodegradabilityprotective coatingкарбид кремниябиодеструкциязащитное покрытие[Smith A.J., Robertson D., Tang M.K., Jackson M.S., Mac Kensis D., Bagg J.
