Influence of Finishing Procedures on the Color Stability and Surface Roughness of Lithium Disilicate and Monolithic Zirconia Oxide
Talal M. Alnassar
Abstract:Aim: This study aimed at evaluating the impact of different adjustments and artificial aging on the color change (ΔE) and surface roughness (Ra) of monolithic zirconia (MLZ) and lithium disilicate (LD) ceramics. Materials and methods: Forty discs were prepared from
two types of MLZs, including ceramill monolithic Zr (CM-Zr) and Prettau PSZ Zr (PP-Zr), and one LD (IPS e.max-LD, IPS-LD). After different clinical adjustments (performed with glazing, bur, bur + glazing, and bur + polishing) and artificial aging (… Show more
