OBJECTIVE: To evaluate the masking ability and translucency of monolithic and bilayer CAD-CAM ceramic structures. METHODS: and TP was investigated for monolithic and bilayer structures over all backgrounds. RESULTS: than the C4-shaded substrate. CONCLUSION: Monolithic veneers were able to mask C4-shaded background but did not mask metallic backgrounds. Bilayer structures showed greater shade masking ability than monolithic structures.
