Abstract
Relevance. The transgingival part of the prosthetic components of implant systems is a substrate for the primary adaptation of soft tissues and the formation of the gingiva collar a complex of tissues acting as a biological barrier and ensuring the normal functioning of artificial supports in the microenvironment of the oral cavity. At the same time, the morphology of the surface of the abutment which will be in constant contact with the gingiva part during the loading period is of great importance. A change in the properties of the surface morphology of the transgingival part of orthopedic structures is fraught with the formation of a microbial bio-film in the subgingival zone with the with the subsequent development of mucositis and peri-implantitis. Based on the above, the study of the surface characteris tics of orthopedic components of implantation systems seems relevant in the light of understanding the pathogenesis of inflammatory processes and assessing risk factors for the development of complications of dental implantation.Purpose. Study of differences in the elemental composition and features (or characteristics) of the surface morphology of orthopedic components transgingival implant abutments from a number of modern manufacturers.Materials and methods. Prosthetic components from five manufacturing companies were selected for the study. For the assessment, elemental analysis of the surface of the components was used using a Hitachi S-3400N scanning electron microscope with an Oxford Instruments X-Max20 energy dispersive spectrometer, as well as morphological analysis using a TESCAN VEGA 3 scanning electron microscope. The samples were assessed for surface uniformity, the presence of inclusions, cracks and marks.Results. The study revealed significant differences in the components both in elemental composition and surface topography. The results obtained can be summarized in the form of a table.Conclusion. The method of comprehensive surface assessment used in the study can be recommended for describing and comparing orthopedic components from different manufacturing companies.
