Effect of surface treatment on bond strength between zirconia and composite resin core material

نویسندگان

چکیده

Purpose: The recent development of enamel-colored translucent zirconia makes it a viable material to produce crowns. However, achieve sufficient surface roughness for bonding, alumina particle abrasion must be employed. In this study, the effects on and sample pretreatment bond strength between composite resin core were investigated compared optimize treatment conditions.Methods: Zirconia specimens abraded with particles bonded trial cores using dual-cure luting agent either an alumina-zirconia adhesive primer and/or porcelain primer. was observed via laser scanning microscopy, evaluated qualitatively.Results: peak-to-valley roughness, arithmetic mean height, root square skewness parameter values significantly increased after abrasion. greater when applied specimens, self-etching cores, prepared without primers. With primer, however, played no role in increasing strength.Conclusion: combination suitable is recommended improve core. Moreover, chemical more effective adhesion than silane coupling fillers.

Effect of surface treatment on bond strength between an indirect composite material and a zirconia framework.

The present study evaluated the effect of various surface treatments for zirconia ceramics on shear bond strength between an indirect composite material and zirconia ceramics. In addition, we investigated the durability of shear bond strength by using artificial aging (20,000 thermocycles). A total of 176 Katana zirconia disks were randomly divided into eight groups according to surface treatme...

Ultrasonic cleaning of silica-coated zirconia influences bond strength between zirconia and resin luting material.

The purpose of this study was to evaluate how ultrasonic cleaning of silica-coated zirconia surfaces would influence the latter's bond strength to resin luting material. Forty zirconia specimens were divided into four groups: one air abrasion group and three silica-coated groups. Silica-coated specimens were cleaned with distilled water using an ultrasonic cleaner after tribochemical silica coa...
