atching the optical properties of dental materials with the natural dentition is crucial for optimal esthetics, and it highlights the importance of appropriate material selection and manufacturing method. 1 A number of variables affect the optical properties of composite resins, including the composition of the organic matrix and inorganic fillers, filler content, particle size, and other additives. 1Composite resin blocks for CAD/CAM are polymerized using standardized industrial protocols under high temperature and pressure, resulting in improved material homogeneity and
