It has been established that the reaction of hydroxyapatite (HA) with a 3 % NaCl solution as the electrolyte of a mouth cavity accompanied by the calcium hydroxide layer deposition at the contact of HA with a titanium implant during a prosthesis aging takes place due to the local loss of a strength as a result of the HA crystallites grinding up. This reaction having a long enough induction period proceeds only on the surface of active centers (the sites with a higher reaction capacity). It has also been shown that the local HA dissolution in the mouth cavity electrolyte is essentially retarded because of a very large difference between the solubility products for HA and Ca(ОН)2 - two solid phases of this reaction system. We have carried out the experimental modeling of the physicochemical interaction of powders of hydroxyapatite with various specific surfaces, microstructures, and defects with a 3 % NaCl solution.
