The aim of the study was to investigate the interaction of experiment samples biomorphic ceramics based on silicon carbide with bone tissue by scanning electron microscopy. To achieve this goal in a laboratory experiment 20 rats underwent implantation of test material samples in the lower jaw bone tissue. Animals were removed from the experiment in terms of 7, 30 and 90 days after the start of the experiment and the subsequent investigation of the material surface and area of it contact with the bone tissue. Based on these results, it was found that the investigated ceramic microarchitectonics promote the process of reparative osteogenesis by providing conditions for colonization of living cells on the surface of the material. It was proved the possible to contact the coexistence of bone and implants of biomorphic silicon carbide with no signs of rejection or its delimitation. Analyzing results of SEM revealed bone adaptation and bone restructuring in the presence of silicon carbide and its germination pores close fit to the material to its surface.
