Furthermore, the emergence of new implant systems has led to improvements in various types of implant-abutment interface connections, necessitating the use of various superstructure options that impact the quality of prosthetic restorations. The aim of this study was to evaluate the impact of various types of superstructures on the outcomes of dental implant-supported prosthetics. Materials and Methods: From 2023 to 2025, 160 patients (86 men and 74 women) aged 31 to 69 years were treated at the Department of Clinical Dentistry of the Ryazan State Medical University, Ministry of Healthcare of the Russian Federation. Patients underwent implantation using the MIS C1 system (Israel), with the installation of single implants followed by prosthetic restoration using standard, cast, milled, and selective laser sintering (SLS) abutments. The study revealed that the bone resorption rate, as measured by CBCT, averaged 0.3 mm after six months of use for prosthetic structures supported by cast and SLS abutments. Implant stability coefficients, determined by frequency resonance imaging, demonstrated high stability over six months of implantation, regardless of abutment type. Microcirculation parameters, determined by laser Doppler flowmetry, showed an increase in hemodynamic activity by six months, averaging 21-22 pfu. In patients with cast and SLS abutments, which was confirmed by a study of implant hygiene with a higher incidence of plaque accumulation in the transgingival portion of the abutments. Conclusion: The obtained results indicate lower clinical efficacy of using these types of superstructures with a conical implant-abutment connection.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>dental implantation</kwd><kwd>implant-abutment connection</kwd><kwd>standard abutments</kwd><kwd>custom abutments</kwd><kwd>bone resorption in the implant area</kwd><kwd>hygiene of the transgingival portion of abutments</kwd><kwd>peri-implant microcirculation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дентальная имплантация</kwd><kwd>соединение имплантат-абатмент</kwd><kwd>стандартные абатменты</kwd><kwd>индивидуальные абатменты</kwd><kwd>резорбция костной ткани в области имплантатов</kwd><kwd>гигиена трансгингивальной части абатментов</kwd><kwd>микроциркуляция периимплантатной области</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Гуськов А.В., Маликов С.Д., Олейников А.А., Шувалов Н.М.
