Purpose:
To study the bonding strength of zirconia ceramics with 4 kinds of luting cement materials.
Methods:
Blocks of sintered zirconia ceramics were cut and randomly divided into 4 groups with 16 slices in each group. They were treated with sandblasting and bonded with 4 kinds of luting cements respectively. After preserved in 37 degrees C distilled-water for 24 hours and 30 days, the shear bonding strength of these specimens was tested and the data were analyzed by SAS6.12 software package and bond section were observed by scanning electron microscope.
Results:
Two-way ANOVA revealed that the group of PanaviaF could attain the highest shear bonding strength: (34.7+/-3.44) MPa (after 24 hours), (31.5+/-3.44) MPa (after 1 month), which was significantly different from other treatment methods (P<0.01). The initial shear bonding strength of the groups of resin-reinforced glass ionomer was (15.5+/-2.71) MPa, (16.0+/-1.77) MPa (after 24 hours) but dropped markedly to (6.80+/-1.24) MPa, (3.38+/-2.32) MPa after 30 days (P<0.05).
Conclusions:
Resin luting cement containing phosphate monomer (MDP) can provide zirconia ceramics a strong and long-lasting bonding. Resin-reinforced glass ionomer can get good bonding strength too, but can't last long.
