Abstract

Although there have been reports on the abrasion of resin cements, cement film thickness was hardly considered.<BR>Takamisawa evaluated the influence of the cement film thickness on the abrasion of non-filler type resin cement, and concluded that there was a close relationship between number of times and depth of abrasion. The rate of increase of the wear depth was affected by the cement film thickness.<BR>Since most resin cements contained microfiller, Variolink (Vivadent) was examined and it was IPSEmpress (Vivadent) cem kit.<BR>Newly-designed appliances to prescribe 3 cement film thicknesses were used, namely 50, 100, and 200 μm, and the abrasion for each thickness in toothbrush abrasion test was observed.<BR>Continuous measurements were made of the sectional profile, wear depth, and surface roughness by scanning laser microscope.<BR>In SEM observation, the abrasion surface showed different aspects between non-filler and microfiller types.<BR>While there was a close relationship between number of times and depth of abrasion as in the case of non-filler type, the amount of increase of the wear depth varied with the cement film thickness.<BR>Test results indicated that the cement film thickness had influence on the abrasion of resin cement, and resistance of abrasion was influenced by filler type and resin matrix.
