Özet
Abtract: This study aimed to compare the effects of silica nanostructure infiltration methods (manual brushing and high‑pressure vacuum infiltration) using two particle sizes (15–35 nm and 55–75 nm) on the bond strength between adhesive resin cement and high‑translucent zirconia (Y-TZP). Ninety-six Y-TZP samples were divided into into six surface‑treatment groups. Airborne-particle abrasion (APA) and tribochemical silica coating (TSC) were applied to sintered Y-TZP. For manual application of 15–35 nm (15-35-man) and 55–75 nm silica powders (55-75-man), a 50 wt% mixture of silica-isopropyl alcohol paste was brushed onto pre‑sintered Y‑TZP. For high-pressure vacuum applications of 15–35 nm (15-35-vac) and 55–75 nm (55-75-vac) silica powders, samples were immersed in a silica–alcohol solution and subjected to a 0.7‑bar vacuum, then sintered. Surface roughness and morphology were analyzed using confocal microscopy, field‑emission scanning electron microscopy, and energy‑dispersive X‑ray spectroscopy. Composite cylinders were cemented using Clearfil Ceramic Primer Plus and Panavia V5, followed by shear bond strength testing after artificial aging. Failure modes were evaluated. Data were analyzed using the Kruskal–Wallis test with Dunn’s post‑hoc test (α = 0.05). Silica nanostructures were homogeneously infiltrated only in the 55-75-vac sample. Manual application caused 55–75 nm silica nanostructures to aggregate on the Y‑TZP surface, increasing surface roughness. The 55–75‑vac, TSC, and APA groups showed significantly higher shear bond strength values (median 12.6, 12, and 11.68 MPa, respectively) than manual infiltration groups (p < 0.05). The 55‑75‑vac group also had the highest proportion of cohesive failures (53.8%), indicating superior resin–zirconia interfacial integrity.
