“Effect of surface treatment of lithium disilicate ceramics on their bond strengths” (original) (raw)

Abstract

ABSTRACT Title: Bond Strength of Lithium Disilicate Ceramic with Different Surface Treatments F Vohra Objective: The objective of this study was to evaluate the effect of post etch cleaning, silane and heated silane on Microtensile bond strength of Lithium-disilicate hot pressed glass ceramic when bonded to composite resin. Methods: 24 blocks of lithium-disilicate were fabricated (Hot Pressing) and bonding surfaces were etched using 9.5% hydrofluoric acid. Seven experimental groups (Including control) resulted from the various surface treatment combinations which included, post-etch cleaning (PEC) (37.5% Phosphoric acid for 1 min , rinse with water for 20 seconds and ultrasonic bath immersion), silane application (S) and heat (100°C for 5 minutes) or air dried silane. Silica based hot pressed ceramic blocks were also fabricated and surface treated to be used as a control group. Ceramic and composite resin blocks were bonded using an adhesive resin and light cured composite resin as ...
