Background. One of the key issues in modern implant rehabilitation in dental endoprosthetics is the overall reduction in rehabilitation time, which is associated with accelerated bone tissue regeneration. Purpose – to develop and investigate glass-ceramic coatings for dental implants that are used under immediate loading and to ensure their ability to simultaneously exhibit biological activity and strength. Materials and Methods. The goal was achieved by developing compositions of glass-crystalline coatings based on titanium alloys with a calcium phosphate silicate glass matrix, modified with biologically active components for dental implantology. Results. Glass compositions based on the R2O–RO–RO2–CaF2–R2O3–P2O5–SiO2 system were modified with a phase-forming component ratio of CaO/P2O5 = 1.28–1.67 and a CaF2 content of 2.0 ÷ 2.5 wt. %. The glass formation region was investigated and the compositions of experimental glasses were synthesised. The peculiarities of the crystallisation mechanism of experimental glasses were established, which consists in the occurrence of phase separation and self-organisation of the structure at the softening temperature, followed by volumetric fine-dispersed crystallisation with a content of crystalline phases of calcium phosphates of 50–60% with a size of 0.1–1 μm under low-temperature heat treatment conditions. The mecha- nism of structure formation of modified calcium phosphate silicate glass materials has been established, which consists in the formation of crystallisation nucleators after glass melting with clear phase boundaries at a viscosity of h = 108.89–9.1 Pa·s, which is a positive trend in the formation of a strengthened sialised structure in a short period of time. Conclusions. Thus, we have developed, researched and analysed the compositions and properties of bioactive glass-crystalline coatings on titanium alloys. The main hypothesis of the study is the ability to exhibit biological activity while ensuring strength by applying a bioactive glass-crystalline coating to the surface of the titanium alloy, which is characterised by its ability to osseointegrate within a short period of time, rapid bone tissue regeneration and non-toxicity.
