Bonding orthodontic brackets to ceramic materials is a challenging procedure; femtosecond (FS) laser conditioning could provide
improved results, but the ideal settings for effective bracket-zirconia bonding have never been established. This study aimed to
analyze the differences in surface roughness and shear bond strength (SBS) produced by different femtosecond laser settings and
establish a protocol to prepare zirconia surfaces for optimal adhesion to metal orthodontic brackets. One hundred eighty zirconia
samples were assigned to six groups according to surface treatment: (1) control; (2) air-particle abrasion (APA); (3) FS laser
irradiation (300 mW output power, 60 μm inter-groove distance); (4) FS laser irradiation (200 mW, 100 μm); (5) FS laser
irradiation (40 mW, 60 μm); and (6) FS laser irradiation (200 mW, 60 μm). Surface roughness was measured. Orthodontic
brackets were bonded to the zirconia specimens, and SBS was measured. SBS in groups 3 and 6 was significantly higher than the
other groups (5.92 ± 1.12 MPa and 5.68 ± 0.94 MPa). No significant differences were found between groups 1, 2, 4, and 5
(3.87 ± 0.77 MPa, 4.25 ± 0.51 MPa, 3.74 ± 0.10 MPa, and 3.91 ± 0.53 MPa). Surface roughness was significantly
greater for FS laser than for control and APA groups (p = 1.28 × 10−8
). FS laser at 200 mW, 60 μm can be recommended as
the ideal settings for treating zirconia surfaces, producing good SBS and more economical energy use. [-]
