Keywords: titanium, ytterbium-doped fiber laser, bond strength, surface roughening, porcelain

Abstract

Aim: The aim of our study is to compare the application of fiber lasers with aluminum oxide sandblasting and CoJet, which is one of the other surface roughening methods used for the first time in this study. Investigating the effect of titanium–porcelain bond strength is another aim of this study.

Methodology: In total, 96 samples of titanium discs (6 mm in diameter and 3 mm in height) were prepared in a CAD/CAM device. Samples were divided into six groups (n: 10), including the control group, according to the applied surface treatments: one-way (horizontal) scanning with a Yb fiber laser, two-way (horizontal-vertical) scanning with a Yb fiber laser, three-way (horizontal–vertical–hypotenuse) scanning with a Yb fiber laser, CoJet, sandblasting, and the control group. After using the different surface treatments on the titanium discs, scanning electron microscope (SEM) imaging, a wettability test, and a profilometer test were applied to the samples in each group. After the surface treatments were applied to the titanium discs, including those in the control group, low heat porcelain (VITA Titanium Porcelain), which was 4 mm in diameter and 3 mm in height, was applied according to the manufacturer's instructions. Afterwards, porcelain samples prepared with titanium inlays were placed in acrylic blocks and kept in 37°C (±1°C) distilled water for 24 hours. Shear tests were applied to the samples embedded in prepared acrylic blocks, and the results were evaluated.

Results: In the statistical evaluation of the obtained data, one-way analysis of variance (one-way ANOVA) was used to compare the statistical differences of the mean values of the bond strength between titanium and porcelain. In our study, Tukey’s HSD and Dunnett’s multiple comparison statistical tests were used to determine the differences among the groups.

Conclusion: According to the results of our study, the highest average bond strength values were obtained from sandblasting and three-way fiber laser roughness. As a result, no statistically significant difference was found among the groups. Although Yb fiber laser application was not found to have a statistically significant effect on titanium porcelain bond strength, this method could be useful for titanium porcelain bonding.
