Objectives: The aim of the present study was to
investigate the shear bond strength of orthodontic brackets to zirconium oxide
infrastructures treated with erbium-doped yttrium aluminum garnet (Er:YAG),
neodymium-doped yttrium aluminum garnet (Nd:YAG) and potassium titanyl
phosphate (KTP) laser modalities in in vitro settings. Materials and Methods: A total of 40 zirconium oxide
infrastructures were prepared with CAD/CAM technology in accordance with ISO
11405 standard. The specimens were divided into 4 groups as following: Er:YAG,
Nd:YAG, KTP, and control groups (n=10). Prior to the application of cementation
of orthodontic brackets, the surfaces of the zirconium oxide infrastructures
were irradiated using selected laser modailites. Shear bond strength tests were
performed on each specimen by using a universal testing machine. Results: The shear bond strength value
of Er:YAG laser group was significantly higher than those of all other groups (p<0.05);
although the bonding strength of Nd:YAG laser was higher than that of the KTP
laser, this difference was not reached statistical significance (p>0.05).
The bonding strength values of Nd:YAG laser group were significantly higher than
that of the control group (p<0.05); and the the bonding strength values of
KTP laser group were significantly higher than that of control group
(p<0.05). Conclusion: The bond
strength between the orthodontic brackets and zirconium oxide infrastructures
was improved upon using all the laser modalities in the present study, among
which, application of the Er:YAG laser was the most successful.
