A method for the in-vivo measurement of wear resistance of restorative materials is described. A profilometer is used to record the reduction in vertical dimension of the test material's occlusal surface. This loss of substance is calculated as the wear resistance index. The technique was used in a 13 month clinical evaluation of 3 different restorative materials, Adaptic, Amalgam (Dispersalloy) and Estic microfill. The procedure is simple in execution and very accurate. Statistical analysis has shown significant differences in wear resistance of the examined materials independent of patient variation. Attrition and abrasion were definitely greater with a standard composite material (Adaptic) than with amalgam and a test composite (Estic microfill). The newly developed composite material utilizing extremely fine filler particles of pyrogenic SiO2 (Estic microfill) was shown to be comparable to amalgam in wear resistance during the 13-month test period.
描述了一种用于体内测量修复材料耐磨性的方法。使用轮廓仪记录测试材料咬合面垂直尺寸的减小。这种物质损失被计算为耐磨指数。该技术用于对3种不同修复材料（Adaptic、银汞合金（Dispersalloy）和Estic微填料）进行的为期13个月的临床评估。该程序执行简单且非常准确。统计分析表明，所检查材料的耐磨性存在显著差异，与患者差异无关。标准复合材料（Adaptic）的磨耗和磨损肯定比银汞合金和测试复合材料（Estic微填料）更大。在13个月的测试期内，新开发的利用热解二氧化硅极细填料颗粒的复合材料（Estic微填料）在耐磨性方面与银汞合金相当。
