|Abstract:||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 plasticswith 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.|
