我们之前曾报道过，将粗颗粒的β-石英玻璃陶瓷插入物（Megafiller）插入复合树脂中可显着降低树脂修复材料的聚合收缩。在这项研究中，我们通过玻璃珠磨损试验和传统刷牙磨损试验检查了 Megafiller 插入对耐磨性的影响。通过使用精确至 1 微米的轮廓投影仪测量磨损测试前后样本的厚度来确定磨损深度。一般来说，复合材料的磨损深度因插入Megafiller而减少，但除少数材料外，有和没有Megafiller的复合材料之间的磨损深度差异并不显着。 Megafiller 在某些复合树脂中的润湿性存在细微差异。
We have previously reported that insertion of coarse particles of beta-Quartz Glass Ceramic Insert (Megafiller) into a composite resin markedly reduced the polymerization shrinkage of resin restorative materials. In this study, we examined the effects of Megafiller insertion on wear resistance evaluated by the glass beads abrasion test, and the conventional toothbrushing abrasion test. The depth of wear was determined by measuring the thickness of the specimen before and after the wear tests using a profile projector accurate to 1 micron. In general, the depth of wear of the composites was reduced by Megafiller insertion, but the differences in the depth of wear between composites with and without the Megafiller were not significant except for a few materials. There were slight differences in the wetness of Megafiller in some composite resins.
