dc.abstract.enThe biomaterials, which are the subject of this work, are the dental restorative materials classified as light cured polymer matrix ceramic composites or resin based composites. The dental composite materials are needed for the repairment of human teeth. Fillings and other dental applications are exposed to the biomechanical loading in the chewing process. The wear resistance and hardness are important functional properties. Currently, nanofiller composites play an important role among dental composites. The objective of this paper was to study and analyze the friction, mechanical and wear properties of the surface of polymer matrix ceramic filed nanocomposites. Three material groups were used, one commercial composite Filek Z550 (3M ESPE, USA) and two experimental com posites Ex-nano(G) and Ex-flow(G). The microindentation tests were conducted on the Micro Combi Tester device (Anton Paar GmbH, Germany). Rotating sliding ball-on-disc friction tests were performed against an alumina ball on 5 N load at 1 Hz in the bath of artificial saliva at 37°C. The linear wear and friction coefficients were evaluated. In the light of the obtained results of contact and friction strength tests, it was found that the performance depends on the production technology of the polymer-ceramic composites. The test results indicate that the share of filler nanoparticles the in experimental composites is advantageous due to the tribological wear.
