A plethora of new low-viscosity composite resin materials, or flowable composites, have been marketed during the last two years, but little has been published about them. The authors describe research in which they compared the properties--filler, depth or cure, flow, wear, compressive strength, diametral tensile strength, indented biaxial flexure strength and toughness--of flowable and hybrid composites. Mechanical property tests (ISO 4049, ISO/DIS 6872) of eight flowable composites and two hybrid composites were conducted. The flowable composite with the least flow was similar to traditional composites. Mechanical properties were generally about 60 to 90 percent of those of conventional composites. The authors conclude that flowable materials should be used with caution in high-stress applications for restorative dentistry.
在过去两年里，大量新型低粘度复合树脂材料，即可流动复合树脂已投放市场，但关于它们的公开报道却很少。作者描述了一项研究，他们比较了可流动复合树脂和混合型复合树脂的性能——填料、固化深度、流动性、磨损、抗压强度、径向拉伸强度、压痕双轴弯曲强度和韧性。对八种可流动复合树脂和两种混合型复合树脂进行了机械性能测试（ISO 4049、ISO/DIS 6872）。流动性最小的可流动复合树脂与传统复合树脂相似。其机械性能通常约为传统复合树脂的60%至90%。作者得出结论，在口腔修复的高应力应用中，应谨慎使用可流动材料。
