Effects of Alumina-blasting and Adhesive Primers on Bonding between Resin Luting Agent and Zirconia Ceramics

Abstract

This study evaluated the effect of alumina-blasting and three commercial adhesive primers on the shear bond strength of a dual-cured resin luting agent to zirconia ceramics. Two different-sized zirconia ceramic specimens were treated with or without alumina-blasting and then treated with one of three adhesive primers. Subsequently, specimens were cemented together with Linkmax HV（GC） . Half of the specimens were stored in water at 37℃ for 24 hours and the other half thermocycled 10,000 times before shear bond strength testing. For groups treated with either alumina-blasting or primer, shear bond strength significantly decreased after thermal cycling. For groups treated with both alumina-blasting and one of the three primers, there were no significant differences in shear bond strength before and after thermal cycling（p＜0.05） . It was thus concluded that the application of each of the three adhesive primers following alumina-blasting was effective for strong bonding of resin luting agent to zirconia ceramics.

Effect of various surface preparations on bond strength of a gingiva-colored indirect composite to zirconia framework for implant-supported prostheses

“…Therefore, excessive surface roughness due to alumina-blasting is not necessary to increase bond strength. These findings are similar to those reported in a previous study, which found that surface roughness was not the only factor in bond strength 31) . Increasing the pressure of alumina-blasting would increase the surface roughness of zirconia frameworks.…”

Combination treatment of tribochemical treatment and phosphoric acid ester monomer of zirconia ceramics enhances the bonding durability of resin-based luting cements

“…The present study revealed that the shear bond strength of EP on ASB was significantly higher (p<0.05) than that of ASB without primer at 24 h. These results suggested that ASB treatment contributed not only to an increase in mechanical retention, but also to the cleaning and activation effects for Y-TZP [33][34][35] . ASB treatment alone barely achieved high bond strength after 30,000 thermal cycles.…”

The effect of preparation order on the crystal structure of yttria-stabilized tetragonal zirconia polycrystal and the shear bond strength of dental resin cements

“…Both the penetration of the resin cement and in situ polymerization are responsible for the bonding of the resin cement to the ceramic restorations [34]. According to Tsuo et al, recommended air-borne particle size for sintered zirconia is 50 m [20]. Another study concluded that air-borne particle abrasion with either smaller (50 m) or larger (110 m) particles is of beneficial for zirconia with a machined surface in terms of shear bond strength [21,35].…”
