Abstract

Objective: Evaluation of the color change of a semileucent ceramic system with different core-veneer thicknesses and backgrounds.

Materials and methods: Thirty disk-shaped specimens with different thicknesses of core-veneer were prepared with IPS-Empress 2 and IPS-Eris glass ceramic and four backgrounds were prepared.

Results: Color differences were significantly influenced by total ceramic thicknesses and backgrounds (p < 0.001).

Conclusion: Thickness and backgrounds caused a detectable color mismatch in clinically relevant core-veneer thicknesses of IPS Empress 2.
