Temperature reaction of tissues when using implants with Calcium-phosphate spraying

Abstract

The authors performed four series of experiments in adult mongrel dogs. They investigated the temperature reaction of tissues in the zone of implanting titanium internal plates of different type (those without holes and those with holes) with hydroxyapatite coating. Depending on the experiment series the bioactive coating was applied by the technique of microarc oxidation (MAO) or by that of high-frequency magnetron sputtering (HFMS). The temperature of tissues elevated within the first two weeks after implantation, and that did not depended on the type of the product and the way of applying the bioactive coating. After three weeks of the experiment the dynamics of temperature reaction depended on the implant type, and the way of applying the coating had no significant effect. Four weeks after implantation the values of the investigated measure normalized in all the series. The obtained data will be used when evaluating circulation features in tissues of the zones of implantation in the products being tested, and they will be taken into account when analyzing the results of histological investigation.
