Modern implantology has a wide range of materials, which have established reputation throughout decades. The mostly wide used material is titanium and its alloys, which have demonstrated satisfactory biological properties and the lack of corrosion. Though, there are data on the possible spontaneous fatigue fractures of jaw because of the disconformity of the mechanical properties of the implant and the bone tissue and the forming of the connective tissue along the material.
This work compares the reaction of tissues to the implantation of different materials, both traditional (TiVT6, Ti-1, 3Si-20Nb, Ti-1, 9Si) and innovative, such as zirconium implants with hydroxylapatite coating with the use of microplasmous spraying. To evaluate the tissue reaction, stereoscanning microscopy with microanalysis was applied. It enables to evaluate both the morphology of peri-implant zone and detect the migration of implant elements into the surrounding tissues.
The results of the research have showed the advantages of the innovative materials, which become apparent in their high osteo-integration properties, providing adherence of implant to alveolar socket. Traditional materials have showed the migration of titanium and silicon into the surrounding tissues and the possible toxic impact on the osteoblastic differentiation.
