Contamination of the surface of dental implants as one of the factors for implantation failure

Introduction: The success of the implantation process depends on several factors, one of the factors is the biological modification of the material from which the implant is made and the peri-implantitis can occur as a failure. Оbjective: The main objective of this research was to determine the chemical elements that dominate the root surface of faild implants.
Materials and methods: For this scientific research we use an electron microscope, which will allow a detailed analysis of the surface of the implants. Analysis of new as well as failed implants. A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning its surface with a focused beam of electrons. For the purposes of this research, 20 implants were used. The samples are divided into two groups, one group includes more expensive implants and the other group includes cheaper implants.
Results: During the research, when analyzing the implants under an electron microscope, traces of chemical elements were found on their surface. All these elements negatively affect the success of the implantation and this is one of the reasons for its failure.
Conclusion: Contamination of dental implants is a key factor in the success/failure of implantation. Traces of organic and inorganic contaminants can be found during the implant cleaning process, surface treatment of Ti, such as acid and sand.
Key words: implant, failure, osseointegration, peri-implantitis, success.
