Evaluation of 24-hour shear bond strength of resin composite to porcelain according to surface treatment

Effects of ceramic surface treatments on the bond strength of an adhesive luting agent to CAD–CAM ceramic

“…Etching and silanization was proposed by several authors as the preferred method to obtain a high bond strength between ceramic and resin composite. 21,27,30,31,35,36 Some of them suggest that the chemical bond promoted by the silane coupling agent was the major mechanism responsible for the adhesion of resin-ceramic systems 12,15,21,24,32,35 and was crucial in creating a durable bond strength. 20,24,27,32,35 Other authors, however, reported that etching has the largest contribution to the final bond strength, as was also noticed in the present study.…”

Bond Durability of Composite Luting Agents to Ceramic When Exposed to Long-term Thermocycling

“…According to the guidelines of the manufacturer, the porcelain surface was etched with HF acid (5%), subsequently silanized and, finally, covered with a hydrophobic adhesive resin. This type of surface treatment has previously been proven to yield the highest bond strengths 14,26,32 even after durability testing. 14,[18][19]24,29 The significantly increased bond strengths of Variolink II to ceramic after thermocycling were reported by Piwowarczyk and others 16 : 6,000 thermocycles) or only a slight decrease after 100,000 thermocycles.…”

Insights on Ceramics as Dental Materials. Part II: Chemical Surface Treatments

“…By adding a third surface treatment, viz. 50 μm air particle abrasion, in addition to acid etching and silanization, the bond strength increased minimally to 12.34 MPa [43]. Etching feldspar-based ceramics with concentrated hydrofluoric acid and then bonded to enamel resulted in a mean shear bond strength of 27.6 MPa.…”
