The aim of this investigation is studying of influence of polishing systems on surface characteristics of ceramic restoration. We have investigated 12 samples of teeth with ceramic inlays fixed on them. Materials and methods of investigation. Two prepared samples were polished using each and every of five polishing systems: Enhance, polishing burs SHOFU, SofLex discs, polishing burs SHOFU using a brush with paste Profylaxpasta CCS, rubber cones (NTI), machine for precision polishing Logitech PM5 using polishing plate made of Aluminum oxide M28. Results: among the samples polished in clinical conditions the lowest roughness average of fixing cement had the samples polished using the Enhance system (Ra=150± 50нм), Sof-Lex discs (Ra=300± 30), rubber cones (NTI) (Ra=270± 30нм). Polishing burs SHOFU using a brush with paste Profylaxpasta CCS had showed higher roughness average (Ra=315± 35нм). Using only polishing burs SHOFU had showed the lowest polishing degree (Ra=490± 80нм), using machine for precision polishing Logitech PM5 using polishing plate made of Aluminum oxide M28 had showed the lowest roughness average (Ra=25± 6нм). Conclusions: obtained data show that the sample consisting of ceramic inlay - fixing cement - tooth enamel, may be polished to the roughness average of mirror surfaces only in the laboratory conditions. In clinical conditions lowest roughness average 3 polishing systems showed Enhance system, Sof-Lex discs, rubber cones (NTI).
