Effect of Aging on Stained Monolithic Resin ‐Ceramic CAD/CAM Materials: Quantitative and Qualitative Analysis of Surface Roughness

ConclusionsThe applied staining protocol significantly increased surface roughness of CAD/CAM materials. Instability of the staining layer on resin ‐ceramic CAD/CAM materials could be anticipated over time as a consequence of toothbrushing, whereas feldspathic ceramic did not suffer from such aging effect.
