Abstract
Objectives: Adults want aesthetic restorations like monolithic zirconia crowns. Due to the unique surface treatment, orthodontists have trouble bonding orthodontic braces to this material. This study examines the shear bond strength (SBS) of metal brackets attached to two zirconia ceramics, surface roughness (SR) following hydrofluoric acid surface treatment, and adhesive residual index (ARI). Materials and Methods: Twenty crowns of monolithic zirconia and twenty crowns of monolithic high transparent zirconia (Zolid-HT/W) were fabricated. The surface was treated with hydrofluoric acid etching. Twenty extracted lower central incisors were prepared and etched with hydrofluoric acid (HF) to serve as the control group. SR, SBS, and ARI were evaluated. Results: Enamel and Zolid-HT/W groups had the greatest SBS and SR values, respectively. Conclusion: With HF surface treatment, Zolid-HT/W and zirconia groups may achieve sufficient bond strength. Clinical significance: To get the best findings about the adhesive strength of orthodontic brackets, a portion of a simulation was conducted in a manner analogous to clinical practice.
