The aim of the work was to study microscopic defects in the proposed materials in which the unwanted defects arose and led to early end of the lifetime. It is a dental implant, which had to be prematurely taken from the oral cavity due to limit conditions of the patient pain.Investigation of chemical elements of dental implant materials has shown the presence of such components, which lead to create undesirable intermediate phases in the structure and therefore the analysis of the implants has been complemented by microscopic evaluation.There are on the part of the dental implant, which interacts with a bone of a patient, the corrosion destruction of the material was visually observed. For this reason, the character and thickness of oxide layer, that negatively affects the living cells of the organism, was also examined on more detail.
