The glas beads abrasion test reported Tani et al (1983) had forseen that the coarsefilled composites would been inferior to microfilled composites in clinical results of wear resistance. The purpose of this study was undertaken to determine an accurate appraisal of wear resistance of different types of the composite resins. The composite resins used in this study are consisted of three highly-loaded coarsefilled composites ; Clearfil AP-X (Kuraray), Z250 (3M) and Beautifil (Shofu), two submicrofilled composites ; Palfique Estelite (Tokuyama) and Palfique Toughwell (Tokuyama), and two micro filled composites ; Silux Plus (3M) and Metafil C (SUN Medical). Five specimens (10x10x1.5mm) of each material were prepared by photo-curing. All specimens were polished with a 1200 grit SiC paper to wear away 200 um from the surface to be tested. After these specimens were kept in a desiccator until they attaine a constant weight, specific gravity of each material was measured. by an electric gravit … More y meter. The specimensfixed in the horizontal drive aim, was reciprocated with a 400 g load of glass beads at a velosity of 120 strokes per minute for 10,000 times, which is equivalent to traveling 2,000 m. The degree of wear was measured by weight loss converted to volume loss with specific gravity of each material. Two trypes of glass beads (Toshiba-Ballotini) slurries were mixed with 14Og the surface-treated glass beads (EGB) to 100ml water. The other slurry was prepared with the suface-nontreated glass beads (GB). Both glass beads have 4Oum in diameter. These devise placed in the open-top stainless steel container like a ship. The slurry poured into the container. Data were analysed by two way ANOVA. It was concluded that the wear with EGB wasmuch larger than GB. The microfilled composite resin showed least wear compare to larger wear of coarsefilled composite resins. This result suggests that the filler particle size is relatively important to wear resistance of the composite resin. Less

据Tani et al（1983）的玻璃珠磨损试验报道，粗填充复合材料的耐磨性在临床结果上不如微填充复合材料。本研究的目的是确定一个准确的评估不同类型的复合树脂的耐磨性。本研究中使用的复合树脂由三种高负荷粗填充复合材料组成；两种亚微填充复合材料Clearfil AP-X （Kuraray）、Z250 （3M）和Beautifil (Shofu)；Palfique Estelite （Tokuyama）和Palfique Toughwell (Tokuyama)，以及两种微填充复合材料；Silux Plus （3M）和Metafil C （SUN Medical）。光固化制备了每种材料的5个10x10x1.5mm的样品。所有的样品都用1200砂砾的SiC纸抛光，使其从待测表面磨损200um。在这些标本被保存在干燥器中，直到它们达到恒定的重量后，测量每种材料的比重。通过电重力…更多的y米固定在水平驱动瞄准架上的试样，以每分钟120次的速度，用400g的玻璃珠往复运动10000次，相当于运动了2000米。磨损程度由重量损失换算成每种材料比重的体积损失来衡量。将两种玻璃珠（Toshiba-Ballotini）浆液与14g表面处理过的玻璃珠（EGB）混合到100ml水中。另一种浆液采用表面未经处理的玻璃微珠（GB）制备。两个玻璃珠的直径都是4微米。这些装置放置在像船一样的开顶不锈钢容器中。浆液倒进了容器。数据采用双因素方差分析。结果表明，EGB的磨损量远大于GB。与粗填充复合树脂相比，微填充复合树脂的磨损最小。结果表明，填料粒径对复合树脂的耐磨性影响较大。少
