Abstract:Objective: The purpose of this study was to compare the effect of accelerated artificial aging using weathering process on color stability of computer-aided design and computer-aided manufacturing (CAD-CAM) materials.
Materials and Methods: Four CAD-CAM materials were tested; Nano hybrid CAD-CAM composite (Tetric CAD “TC”) , hybrid ceramic (Vita Enamic “VE”), Advanced Lithium disilicate (CEREC Tessera “CT”) and Lithium disilicate (IPS e.max CAD “EM”) . Each group material contains nine samples (n=9). Color … Show more
