“…Due to the development of dental technology, lasers are commonly used in dental procedures and in the surface treatment of dental materials. Studies have shown that laser applications, such as CO 2 (carbon dioxide), Er:YAG (erbium, yttrium, aluminum, garnet), Nd:YAG (neodymium-doped, yttrium, aluminum, garnet), and Er,Cr:YSGG (erbium, chromium: yttrium-scandium-gallium-garnet) alter the material surface and create a larger area for bonding [9, 15–20]. In their study, Murray et al [16] demonstrated that laser etching the surface of a NiCr alloy produced better results than sandblasting with regard to resin bonding.…”

Objectives. The aim of this study is to investigate the shear bond strength of an acrylic resin to titanium after different surface treatment methods. Material and Methods. A total of seventy-two disc-shaped specimens (10 mm×10 mm×2 mm) were prepared from titanium alloy. The specimens were randomly allocated to six equal groups: Group S (sandblasting), Group MP (metal primer), Group 10W (fiber laser 10 W), Group 20W (fiber laser 20 W), Group 10WMP (fiber laser 10 W+metal primer), and Group 20WMP (fiber laser 20 W+metal primer). All of the specimens were thermocycled up to 5000 cycles. After thermal cycling, a shear bond strength test was conducted. The shear bond strength data were analyzed with one-way ANOVA and Tukey’s post hoc pairwise comparisons (p<0.05). Results. While the highest values were determined in Group MP, the lowest values were observed in Group S. Additionally, Group MP exhibited significantly higher shear bond strength values than any of the other groups (p<0.05) except Group 10WMP. Similar results were observed between Group MP and Group 10WMP (p>0.05). The groups in which a metal primer was applied (Group MP, 10WMP, and 20WMP) showed significantly higher values than Group S. The shear bond strength values of Group 10W and Group 20W were similar. Conclusions. The application of a metal primer significantly improved the bond strength of acrylic resin to titanium. Fiber laser application may be an alternative method to sandblasting for improving the bond strength of acrylic resin to titanium.

“…On the other hand, the findings of the present study disagreed with those of Kirmali et al [50] who found that no significance difference in the bond strength between zirconia and resin cement when the zirconia surfaces treated with Er:Cr YSGG laser and tribochemical silica coating. Several previous studies [49,51,52] high-lightened the effect of different power settings of on the bond strength between zirconia and resin cement and compare with air-particle abrasion, tribochemical silica coating and other types of laser irradiation. Zeidan et al [51] evaluated the effect of different output powers (2.0 W, 2.5 and 3W) of Er,Cr:YSGG laser and the association with tribochemical silica coating on the bond strength between zirconia ceramic and two resin cements.…”

Objective: The purpose of the study was to evaluate the effect of different preparation designs and different surface treatments on the fracture resistance of monolithic zirconia inlay-retained fixed dental prosthesis [IRFDP]. Material and methods: Forty-five translucent zirconia IRFDPs were divided into three groups according to preparation designs (n = 15); group I: proximal box, group II: inlay-box and group III: butterfly wing (modified inlay). Each group was further subdivided into three subgroups according to the surface treatments utilized (n = 5); sandblasting, tribochemical silica coating (Cojet system) and erbium, chromium: Yttrium, scandium, gallium, garnet (Er, Cr: YSGG) laser irradiation. All zirconia IRFDPs were cemented to their respective resin models using selfadhesive resin cement. All cemented IRFDPs were subjected to fracture resistance test using universal testing machine. The initial fracture site was determined by using a stereomicroscope (x6.7magnification). Two-way analysis of variance (ANOVA) was used to evaluate the effect of different designs, different surface treatments and their interaction on the mean fracture resistance. Bonferroni’s post-hoc test was used when ANOVA is significant (P ≤ 0.05). Results: Butterfly wings design showed the highest fracture resistance values followed by inlay and box designs respectively (P ≤ 0.05). Sandblasting and Cojet showed significantly the highest mean fracture resistance values than Laser with no significance difference between them. Conclusion: The butterfly wing design increased the fracture resistance of the zirconia IRFDPs. Sandblasting and tribochemical silica coating of zirconia surfaces had a greater effect than Er, Cr: YSGG laser to gain higher fracture resistance of zirconia IRRDPs.KEYWORDSInlay-retained FDPs; Monolithic zirconia; Preparation designs; Surface treatments; fracture resistance.

“…[30][31][32][33] With the objectives of enhancing bonding potential by creating Cr:YSGG laser at 3 W in the present study resulted in a change of the zirconia surface with a significant roughness increase, while cell growth and proliferation were significantly lower than the AS and the SIE groups, which is in accordance with other published papers. 34,35 This may be due to the surface topography created by the laser energy and the zirconia absorbing capacity of the wavelength. The increase in temperature and surface destruction due to laser absorption by ceramic creates some porosity on the surface, inducing an augmentation of micromechanical retention.…”

Aim:The aim of this study was to characterize the surface of zirconia subjected to different treatments and evaluate its effect on cell adhesion and proliferation. Materials and methods:A total of 80 zirconia disks were divided into four groups (n = 20) according to the surface treatments used: group I: as-sintered (AS), no surface treatment applied; group II: abrasion treatment applied using Rocatec (ROC; 3M ESPE) system with silica-coated alumina powder of grit size 110 μm; group III: erbium, chromium:yttrium, scandium, gallium, garnet (Er, Cr:YSGG) laser (LAS; BIOLASE) was used at a frequency of 20 Hz and output power of 3 W; and group IV: specimens were subjected to the selective infiltration etching (SIE) technique. Surface characterization was evaluated for the different groups (roughness, hardness, and morphology), and cell behavior (adhesion and proliferation) was tested (α = 0.05). Results:The ROC group reported a significant increase in surface roughness (2.201 ± 0.352) and Vickers hardness (1758 ± 16.6) compared with the other surface treatments. The SIE surface-treated group reported a significantly higher number of cells (64.5 ± 2.6 and 53.5 ± 2.2 respectively) compared with the other surface-treated groups. Conclusion:The SIE is a promising surface treatment for zirconia that significantly enhances cell adhesion and osseointegration.Clinical significance: The SIE treatment of zirconia implants may help in a faster and better osseointegration.
