The surface of two dental implant systems, “Nobel Biocare” and “Alpha BiO”, and metal-containing nanoparticles, isolated from the tissues surrounding dental implants, has been investigated. The implant surface structure, the elemental and phase composition of particles, and their arrangement in the granulation tissue have been studied by X-ray tomography, transmission and scanning electron microscopy, z-contrast scanning transmission microscopy, electron diffraction, and energy-dispersive mapping, using microscopes Quanta 200-3D, FEI Тechnai Osiris at an accelerating voltage of 200 kV, and an X-ray microtomograph TOMAC. An analysis of the relief indicates that the emission of nanoparticles from the “Alpha BiO” implant surface to the adjacent tissues is more likely than from the “Nobel Biocare” implant surface. The particles of micrometer and submicrometer sizes of “Nobel Biocare” implants are found to consist mainly of titanium dioxide of both modifications, rutile and anatase, whereas in the case of “Alpha BiO” implants, along with titanium dioxide and titanium nitride, there are aluminum oxides in the particle composition. The elemental composition of nanoparticles is more diverse; it includes Fe, Ca, Na, Cl, S, Si, P, etc. It is revealed that microbial contamination does not always play the leading role in the suppression of previously obtained osteointegration.
