The aim of the research is to study the physical and mechanical parameters of the bases in removable laminar dentures after modification of their surface.Materials and methods: the studied samples were divided into two groups (group I – acrylic plastics, and group II – acrylic plastics with fullerene С60 nanocoating), 50 samples in each group. The coefficients of water absorption, water solubility, microhardness and deformation characteristics of materials were studied.Results and conclusions: The material covered with fullerene С60 has a lower coefficient of water absorption and water solubility, which amounted to 0.55% and 0.23%respectively, from the initial weight of samples, as compared with acrylic plastics without coating (0.71% and 034%, respectively). The strength parameters of samples of group ІІ were higher by 13.5% as compared to group І. The given results of water absorption and water-solubility show that acrylic plastics with fullerene С60 molecules coating has a lower coefficient of water absorption and water solubility, in comparison with acrylic plastics without coating. This indicates a higher degree of resistance to biodegradation of the modified surface material, in turn reducing the washing-out of residual monomer from the denture, which directly improves the strength parameters of the acrylic plastics and can prevent the development of denture stomatitis.
