【摘要】 目的考察不同方法合成的金刚石对口腔复合树脂挠曲强度的影响。方法对爆轰法纳米金刚石(DND)、静压金刚石(SPD)和爆轰法聚晶金刚石(PCD)3种金刚石做了并行实验,使用相同的加入量、相同的改性和合成方法,制备出3组树脂;另做不加金刚石的空白试样。对4组树脂的挠曲强度按照YY1042-2003的要求进行测试。结果 DND和SPD的加入分别使复合树脂的挠曲强度提高了117.2%和103.1%,而PCD对树脂无明显的增强效果。结论 DND和SPD对树脂有显著的增强作用,可使其挠曲强度数值提高1倍以上;PCD对复合树脂无明显的增强效果。 更多还原
【Abstract】 Objective The purpose of this study was to assess the effects of differently synthesized diamonds on the flexural strength of dental resins.Methods Three groups resins were prepared in the same modify and compound process respectively with uniform quantity of detonation nanodiamond(DND),still pressure diamond(SPD), and polycrystalline diamond(PCD).Resin without diamond was prepared as reference sample.Flexural strength of the four groups resins were measured by the method outlined in YY1042-2003... 更多还原
