Comparative evaluation of dental implant systems in the context of import substitution

Relevance. This study aimed to compare different dental implant systems in light of previously reported spontaneous and load-induced release of nanoand microparticles from implant surfaces. Despite the use of various surface treatment methods and titanium-based alloys in the manufacture of certified medical devices, inflammatory complications such as peri-implant mucositis and peri-implantitis may still occur. In addition, delayed degradation of the implant surface may occur even after successful osseointegration. These findings underscore the need to develop improved alloys and surface coatings and to further investigate the causes of inflammatory complications associated with dental implants.

Materials and methods. The stability of the surface oxide layer was evaluated in six dental implant systems: Astra Tech (Austria), Neobiotech (Korea), Nobel Replace (Switzerland), Alpha Bio (Israel), Straumann (Switzerland), and Dental Synthesis (Russia). The analysis was performed using advanced techniques, including X-ray microtomography, X-ray fluorescence analysis, scanning electron microscopy, transmission electron microscopy, and dynamic light scattering.

Results. The carbon coating applied to domestically manufactured Dental Synthesis implants to reduce metallic nanoparticle release remained effective under mechanical loading.

Conclusion. This laboratory study provided a basis for further investigation of the long-term clinical performance of these dental implant systems.
