Relevance. The questions of research of physical and chemical characteristics of reinforcing tapes, peculiarities of chemical connection of composite material and reinforcing component of the splint, physical indicators of strength of their connection, optimal thickness of composite material for reinforcing tape covering remain not fully studied and require further work in this direction in order to optimize splinting stages of mobile teeth in various clinical situations and nosological forms of diseases. The aim of the study - to study the microscopic structure of splinting constructions containing in their structure reinforcement tapes based on organic and inorganic matrices. Material and research methods. 10 groups of 10 specimens of splinting construction, with different chemical composition of reinforcing tapes, 8 of which were made using tapes based on inorganic matrix, 2 - based on organic. Results of the study. Microscopic examination of the splinting samples showed good integration of the composite polymer matrix into the structure of the tapes in the samples using inorganic matrix-based tapes. Peripheral layer delamination was not detected, pores in the splint thickness were absent or were single, which may be due to silanization of glass fibers incorporated into the thermoplastic polymer and light-curing composite matrix. Conclusion. Resin-impregnated inorganic parallel fiberglass tapes impregnated in the factory showed an advantage compared to woven and braided tapes and unimpregnated tapes.
