摘要: The two-body and three-body wear of glass-ionomers (GIC), visible light cured (VLC-GIC), composites were compared. simulations performed for the in an artificial mouth with so-called ACTA machine. tested materials different conventional glass-ionomers, composites, amalgam. rates 8 specimens each material 16 test After 10(5) cycles testing device, shapes measured. All measurements related to rate For method, worn qualitatively judged by scanning electron microscopy. two methods lead similar results slight differences ranking. Amalgam showed lowest both methods. Photac Fil, a newly developed VLC-GIC, dramatically lower resistance than GIC Further investigations are necessary identify material-specific parameters influencing behaviour relation
