The aim of this study was to examine two-body wear testing of flowable resin composites for posterior tooth restoration, using a mechanical loading device in vitro.The cavities were treated with each adhesive system according to the manufacturer instructions, and filled with each flowable resin composite (Clearfil Majesty LV:MLV, Estelite Flow Quick:EFQ, Beautifil Flow Plus F00:BF00, and MI Fill:MIF). Clearfil Majesty was used as the control. The specimens were subjected to an in vitro two-body wear test using a mechanical loading device at ceramic stylus (Aluminum nitride).The mean wear volume of respective materials after 40,000 cyclic loadings were as follows; MLV:0.268 mm3, EFQ: 0.140 mm3, BF00:0.008 mm3, MIF: 0.026 mm3 and the control: 0.013 mm3. Although their filler amounts were less than that of the control, BF00 and MIF showed high wear resistances equal to that of the control at every loading time.

本研究的目的是检查两体磨损试验的流动树脂复合材料的后牙修复，使用机械加载装置在体外。洞处理与每一个粘合剂系统根据制造商的说明，并填充每一个流动树脂复合材料（Clearfil陛下LV：MLV，Estelite流快速：EFQ，Beautifil流加F00：BF00，和MI填充：MIF）。Clearfil Majesty用作对照。 使用陶瓷触针（氮化铝）的机械加载装置对样本进行体外两体磨损试验。在40，000次循环加载后，各种材料的平均磨损体积如下：MLV：0.268 mm3，EFQ：0.140 mm3，BF 00：0.008 mm3，MIF：0.026 mm3和对照：0.013 mm3。尽管BF00和MIF的填充量小于对照，但它们在每个加载时间都表现出与对照相当的高耐磨性。
