Materials and Methods: The materials evaluated were CEREC Blocs (Dentsply Sirona), Initial LRF (GC) and Amber Mill (HASS Corp). All the samples (n=30) were subjected to simulated brushing (100,000 cycles). The wear was assessed by superimposing pre- and post-brushing scans obtained with an intraoral optical scanner (CEREC Primescan; Dentsply Sirona, Germany), which was then imported into the OraCheck 5.0 software (Dentsply Sirona, Germany). Results: The CAD/CAM ceramic materials tested showed no statistically significant differences in terms of the average volumetric wear (p-= 0.455). Conclusion: Therefore, it can be concluded that the ceramic materials have a good behavior under simulated brushing, without significant volumetric alterations.es-ESVolumetric analysisSimulated brushingCeramicWear testARTÍCULO10.24018/ejdent.2023.4.1.239
