Bond Strength of Veneering Porcelain and Resin Cement to Zirconia Core Treated with a Novel Acid Mixture

Abstract

Objective: The aim of this study was to investigate the effect of immersion of zirconia core in a novel acid mixture (hydrofluoric: nitric acid) with four mixing ratios and two immersion times as a surface treatment method on the shear bond strength (SBS) of veneering porcelain and microshear bond strength (µSBS) of adhesive resin cement to zirconia core.
