The objective of the study was to evaluate the volumetric wear of four composite materials for CAD/CAM (computer-aided design/computer-aided manufacturing) systems. The materials evaluated were: Cerasmart (CER), Shofu Block HC (SBH), Tetric CAD (TEC) and Brava (BRA). All the samples (n = 40) were subjected to simulated brushing (100,000 cycles). Wear was evaluated by superimposing pre-and post-brushing scans obtained with an intraoral optical scanner (CEREC Primescan; Dentsply Sirona, Germany), which were subsequently imported into the OraCheck software 5.0 (Dentsply Sirona, Germany). The data were analyzed by ANOVA test and Tukey's HSD test was used for multiple comparisons. Cerasmart showed the least wear after brushing. All the tested materials exhibited mass loss.
该研究的目的是评估四种用于计算机辅助设计/计算机辅助制造（CAD/CAM）系统的复合材料的体积磨损情况。所评估的材料有：Cerasmart（CER）、松风Block HC（SBH）、Tetric CAD（TEC）和Brava（BRA）。所有样本（n = 40）都进行了模拟刷牙（100,000次循环）。通过叠加使用口腔内光学扫描仪（CEREC Primescan；德国登士柏西诺德）获得的刷牙前后扫描图像来评估磨损情况，随后将这些图像导入OraCheck软件5.0（德国登士柏西诺德）。数据通过方差分析进行分析，并用Tukey's HSD检验进行多重比较。Cerasmart在刷牙后显示出最少的磨损。所有测试材料都出现了质量损失。
