Özet
Objective: The purpose of this study was to analyze the shear bond strength of orthodontic metal braces to restorative materials with various constituents and manufacturing methods after different surface conditioning methods. Methods: The samples were prepared from Vita Mark II, Shofu Block HC, Brilliant Crios computer-aided design/computer-aided manufacturing blocks, and Gradia Direct composite restorative material, and they were exposed to 5000 thermal cycles. Fabricated samples were divided into 6 groups based on the surface conditioning method (n = 12): control (no conditioning); etching with hydrofluoric acid; sandblasting with aluminum oxide; tribochemical silica coating with CoJet sand; bur abrasion; Monobond Etch and Prime application. The surface characteristics of the restorative materials were analyzed with a scanning electron microscope. The universal adhesive was applied to the specimens, and orthodontic braces were bonded with a light-cure adhesive paste. After thermal cycling, shear bond strength values were measured, and the adhesive remnant index was recorded. Two-way analysis of variance and Tukey tests were used for statistical analysis. Results: Both the surface conditioning method and the material type significantly affected shear bond strength values. In addition, the interaction between these variables was significant (P < .001). Control groups of all restorative materials had significantly the lowest shear bond strength values. Conclusion: Surface conditioning methods significantly enhanced the shear bond strength. Control groups of Vita Mark II and Shofu Block HC demonstrated shear bond strength values lower than the acceptable limit, but the rest of the groups showed adequate adhesion (above 6 MPa). Consequently, clinicians can prefer Monobond Etch and Prime along with a universal adhesive as a safer surface conditioning method.
