Effect of Different Surface Treatments on the Surface Roughness and Orthodontic Bond Strength of Partially-stabilized Zirconia
Abstract
Objective: To investigate the effect of different surface treatments on the surface roughness (Ra ) and shear bond strength (SBS) of partially stabilized zirconia (Y-PSZ) with different yttrium content.
Materials and Methods: Zirconia samples were milled from 5Y-PSZ and 4Y-PSZ disks and divided into 5 groups: Control (C), sandblasting (APA), single-step selfetch primer etching (MEP), Er:YAG laser (ER), and femtosecond laser (FS) irradiation (n=11). Surface Ra was measured and metallic mandibular incisor brackets were bonded. SBS test was performed after thermocycling. Data were analyzed using two-way ANOVA and Tamhane’s T2 tests (α=0.05).
Results: Only surface treatment affected Ra and SBS (p<0.001). FS groups had the highest (p<0.001), and C groups had the lowest values Ra (p≤0.001). MEP groups had lower Ra than ER and APA (p≤0.002). FS and APA groups resulted in the highest SBS (p<0.001), while MEP groups achieved significantly higher SBS than ER groups (p<0.001). The C group showed the lowest SBS (p<0.001).
Conclusion: Within the limitations of this in vitro study, sandblasting and FS irradiation was found to be the most effective surface treatments for metallic bracket bonding to Y-PSZ.
