ABSTRACT
PURPOSE:
To evaluate the effect of surface conditioning on the shear bond strength of zirconium-oxide ceramic to 4 luting agents. MATERIAL ANDMETHODS:
A total of 120 disk-shaped zirconium-oxide ceramic blocks (3Y-TZP, Kyoritsu, Japan) were treated as follows (1) Sandblasting with 110 microm aluminum-oxide (Al2O3) particles; (2) tribochemical silica coating (Rocatec) using 110 microm Al2O3 particles modified by silica; (3) no treatment. Then zirconium-oxide ceramic blocks bonded with 4 luting cements (RelyX luting (3M ESPE), Maxcem (Kerr), Nexus3 (Kerr), Rely X Unicem (3M ESPE)). Each group was tested in shear bond strengths by UTM. A 1-way analysis of variance and 2-way analysis of variance was used to analyze the data (alpha = .05).RESULTS:
RelyX unicem in combination tribochemical silica-coating produced a highest bond strength (P < .05). Air abrasion group and Rocatec treatment groups resulted in significantly higher than no conditioning group (P < .05). RelyX Luting groups showed lower bond strength than other groups. There were significant differences among groups (P < .05).CONCLUSION:
Within the limitation of this study, RelyX Unicem cement provided the highest bond strength and Rocatec treatment enhanced the bond strength.
