The article concerns the biological and electrochemical degradation of metallic implants in vivo and in vitro studies. The in vivo research dealt with degradation of plates used to join bones, as well as endoprostheses. The most common damages were: metalosis, breaking in the microstructure changes, breaking in area of holes, as well as plastic deformation throughout the length of an implant. The material used for the research was pure titanium. The analysis of the reasons of the damages included the observation of the surface scrap, which was conducted by the use of Philips XL30 electron scanning microscope. In vitro studies concerned the impact of aggressive environments on the external surface of implants. The titanium pins were immersed in the bacterial solution and corrosion tests were carried out in two solutions simulating the human body (Ringer’s and Artificial Saliva). It was found that after a period of 6 months, the bacteria began to settle on the surface. As a results of the electrochemical corrosion processes: general etching, appearance of micropores and intensively corroded areas were observed on the surface. Based on in vivo and in vitro studies, the susceptibility of titanium implants to degradation in the human body is assumed.
