Effect Of Surface

SummaryMonolithic zirconia restorations offer superior mechanic properties and improve indication of non-metallic restorations. Monolithic restorations eliminate bonding and chipping problems mostly seen in zirconia restorations. However, optical properties are insufficient. Colouring or staining is offer possibility to mask the opaque view of restoration. Polishing and glazing are also surface treatment methods for monolithic zirconia.In this study effect of surface treatment methods on final view of zirconia were evaluated. For this purpose 30 monolithic zirconia samples (inCoris TZI, Sirona, Bensheim, Germany) were prepared. The samples were divided into 3 groups: In group A (n=10), glazing was performed using Vita Glaze (Vita Zahnfabrik, Bad Saeckingen, Germany); In group B (n=10), polishing was performed by using Soflex polishing system (3M-ESPE, Neuss, Germany); in Group C (n=10), polishing and glazing were performed. Before and after the applied the surface treatment methods, colour measurements were performed with a spectrophotometer (Vita EasyShade Advanced, Vita Zahnfabrik, Bad Saeckingen, Germany). Data were analysed using paired sample t-test at the p≤0.05 level and one-way analysis of variance (ANOVA) combined with Tukey’s multiple comparison tests.In all groups there were alterations in colour values; however, ΔE< 3.7 and the colour changes were undetectable.
