Abstract


Resume. This article presents the results of research of interaction biomorfnoyi ceramics based on silicon carbide with bone experimentally by scanning electron microscopy. This material was developed at the Institute of Semiconductor Physics named after VE Lashkarev NAS of Ukraine, by impregnating silicon “channel” carbon matrices that are due to pyrolysis (obvuhlennya) different varieties of wood. To achieve this goal in an experiment on laboratory rats held 20 implants samples studied material in the bone of the lower jaw. Animals withdrawn from the experiment in terms of 7, 30 and 90 days after the experiment began, followed by the study of the surface and the contact material with bone tissue. Based on the results, found that micro-architectural study ceramics percolation process promotes reparative osteogenesis by providing conditions for colonization of the surface material of living cells. The possibility of contact coexistence bone and implants biomorfnoho silicon carbide with no signs of its rejection or disassociation In analyzing the results of SEM area contact biomorfnoho silicon carbide with bone tissue found adaptation and restructuring bone in the presence of silicon carbide and its germination in the pores of the material with a snug fit its surface.
