“…[11] Previous studies have shown that femtosecond laser can create precisely controllable micro-scale topography on zirconia surfaces, making it a suitable noncontact method for enhancing the surface roughness of zirconia ceramics. [12][13][14] In addition to microscopic roughness, the chemical composition of the implant surface is another important factor determining osseointegration. Calcium phosphate (CP) is the primary component of bone mineral.…”

Zirconia implants have great application prospects due to their favorable biocompatibility and esthetic properties. However, the percentage of osseointegration of zirconia implants is lower than that of titanium implants. This study, structures bioactive surfaces on zirconia using a femtosecond laser combined with hydroxyapatite (HA) crystals and evaluates the surface morphology, functional groups, crystal phase, mechanical performance, and cell response. The results revealed that calcium phosphate deposition coincided with the establishment of micro‐grooves on the zirconia surface. The crystal composition and flexural strength of zirconia showed no significant changes after the surface treatment. Furthermore, the modified surface promoted cell adhesion and proliferation through adjustments in cell morphology. The findings suggest that the combination of femtosecond laser and HA crystals offers a clean, rapid, and controllable approach to preparing bioactive surfaces for zirconia implants.

“…The establishment of a robust and long-lasting bond between resin cement and ZrO 2 is widely recognized as an essential requirement for clinical success [12]. Consequently, the objectives of this study were: (a) to compare and contrast various surface conditioning methods, in particular TBC and femtosecond laser irradiation on enclosed mold-shear bond strength (EM-SBS) between resin composite and ZrO 2 substrate, and (b) to analyze the types of failures observed during debonding.…”

This laboratory study aimed to evaluate the effect of different surface patterns using femtosecond laser treatment on the enclosed mold shear bond strength (EM-SBS) of resin composite to zirconia (ZrO2) surfaces and to contrast it with the widely used tribochemical silica coating (TBC) surface conditioning method. A set of fifteen rectangular ZrO2 blocks were randomly divided into five groups according to surface pretreatment: Control G0—no treatment; G1—TBC with silane application; G2—femtosecond laser irradiation with horizontal lines 30 µm apart; G3—femtosecond laser irradiation with horizontal lines 15 µm apart; and G4—femtosecond laser irradiation with cross lines 30 µm apart. The pretreated surfaces were characterized by a surface profilometer, tensiometer and scanning electron microscope. The EM-SBS of resin composite stubs to ZrO2 was measured followed by fractographic analysis. The surface roughness and water contact angle were observed to be statistically higher among the femtosecond laser groups compared to the TBC and control groups. The G4 group exhibited the highest EM-SBS among all the groups, irrespective of the ageing conditions used. At the end of 5000 thermocycles, G4 exhibited EM-SBS of 14.05 ± 4.21 MPa compared to 13.80 ± 3.01 MPa in G1 and 5.47 ± 0.97 MPa in G0. The two-way ANOVA revealed a significant effect of both study groups and ageing conditions on the EM-SBS (p < 0.001). Utilization of femtosecond laser technology holds promise as a potential and alternative mechanical retention approach for enhancing the bonding strength of the resin composite to ZrO2.

SUMMARY Background Translucent monolithic zirconia ceramics have been applied in dental clinics due to their esthetic translucent formulations and mechanical properties. Considering inherent ceramic brittleness, adhesive bonding with resin composite increases the fracture resistance of ceramic restorations. However, zirconia is a chemically stable material that is difficult to adhesively bond with resin. Objectives To investigate the influences of SiO2-ZrO2 coatings on adhesive bonding of zirconia and the surface characterization of those coatings. Methods and Materials Translucent zirconia discs were classified into groups based on surface treatments: CT (control), SB (sandblasting), C21(SiO2:ZrO2=2:1), C11(SiO2:ZrO2=1:1), and C12 (SiO2:ZrO2=1:2) (n=10). Surface characterization of coatings on zirconia were analyzed by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), surface roughness assessment (Ra), X-ray diffraction (XRD), water contact angle (WCA), translucency parameter (TP), and shear bond strength (SBS). Two-way ANOVA for shear bond strength results and ANOVA for Ra and WCA were performed. Results SEM images revealed SiO2 islands on zirconia disks coated with SiO2-ZrO2. Surface roughness of C12, C11, and C21 groups was significantly larger than those of groups SB and CT (p<0.05). XRD results showed that phase transformation of zirconia disks was detected only in the SB group. In addition, SiO2-ZrO2 coatings reduced WCA. The translucency decreased only in group C21. Group C11 showed the highest shear bond strength under both aging conditions. Conclusion SiO2-ZrO2 coating is a promising method to enhance the adhesive resin bonding of translucent zirconia without causing phase transformation of translucent zirconia.
