Background: Dental zirconia has been widely used due to its superior mechanical properties. However, traditional etching techniques and surface treatments are generally ineffective on zirconia surfaces due to its inertness and lack of a silica phase. Hence, various surface treatments are applied to improve bonding to zirconia.
Objectives: The aim of this study was to evaluate the effect of three different surface treatments: low pressure air borne particle abrasion, selective infiltration etching and fusion sputtering on bond strength to both Tetragonal zirconia and Cubic zirconia.
Materials and Methods: Ninety two specimens of zirconia were used in this study. Two of …
