摘要: AbstractIt evaluated the effects of different zirconia surface treatments on bond strength a resin cement to Y-TZP (yttria-stabilized tetragonal zirconia) ceramics, as well their phase-transformations. 75 blocks (5 mm × 5 mm × 4 mm) were assigned into five groups (n = 15): (tribochemical silica coating - TBS) was abraded by coated alumina particles followed silanization; (GLZ1) received application thin layer low-fusing porcelain glaze, hydrofluoric acid (HF) etching for 1 min; (GLZ5) glaze + HF 5 min; (GLZ10) application + HF 10 min; (GLZ15) + HF 15 min. After etching, all specimens washed, dried and silanized. Cylinders composites (diameter: 3.25 mm; height: 3 mm) cemented using cement. All subjected aging (10,000 thermal cycles 90 days storage), tested under shear conditions, and...
