Abstract:
Objective:To investigate the effects of 3 adhesives on the bond force and durability of polished and glazed zirconia ceram-ics to orthodontic metal brackets respectively.Methods:Universal adhesives,Single Bond Universal(SBU)and Prime&Bond Universal(PBU)were respectively used to bond polished and glazed zirconia to metal braces of maxillary central incisors using TransbondTM MIP(TM)as the control.The shear bond strength(SBS),the fracture morphology and adhesive residual index(ARI)were examed after wa-ter bath or water bath-thermal cycling storage.Results:The adhesive(P＜0.001)and storage conditions(P＜0.001)significantly af-fected the shear bond strength of zirconia to brackets.There was no significant difference between the polished or glazed groups(P=0.09).SBU showed the stronger SBS and lower ABI,there were significant differences in ARI scores among the 3 cements(P＜0.001).Conclusion:SBU may have better bonding performance than PBU and TM in the orthodontic bonding of polished or glazed zir-conia surfaces to the zirconia ceramics.
