The aim of this study is to evaluate the effect of aging on resin bond strength to translucent zirconia treated with the most clinically used bonding procedures. Monolithic translucent zirconia-based ceramic (3Y-TZP) blocks were surface treated using airborne-particle abrasion with alumina particles (AP) or silica-coated alumina particles (SC) then bonded to resin composite blocks using a resin cement system containing a silane coupling agent and an adhesive with a phosphate (MDP) monomer. Bar-shaped specimens (bonding area: 1 mm²) were fabricated (n = 30) and stored in 37 °C distilled water for the following time before testing: 7 days (SCI and API); 1 year (SC1 and AP1); and 2 years (SC2 and AP2). Specimens were loaded to failure under tension using an Instron testing machine. Microtensile bond strength (σ_f) data was statistically analyzed using Weibull distribution, analysis of variance (ANOVA) and Tukey tests (α = 0.05). Failures were evaluated using fractographic principles. Mean σ_f values significantly decreased after 2 years of water storage (SC2 and AP2) (p < 0.05), although there was no difference in the Weibull modulus. All specimens failed cohesively within the adhesion zone at the zirconia-cement adhesive interface.

本研究的目的是评估老化对使用临床最常用的粘合程序处理的半透明氧化锆的树脂粘合强度的影响。整体半透明氧化锆基陶瓷 (3Y-TZP) 块使用氧化铝颗粒 (AP) 或二氧化硅包覆氧化铝颗粒 (SC) 的空气颗粒磨损进行表面处理，然后使用含有硅烷偶联剂的树脂水泥系统粘合到树脂复合块上剂和粘合剂与磷酸盐 (MDP) 单体。制作棒状试样（粘合面积：1 mm ²）（n = 30）并在测试前在 37 °C 蒸馏水中储存以下时间：7 天（SCI 和 API）；1 年（SC1 和 AP1）；和 2 年（SC2 和 AP2）。使用 Instron 试验机在张力下加载试样至破坏。微拉伸结合强度（σ_f ) 使用威布尔分布、方差分析 (ANOVA) 和 Tukey 检验 (α = 0.05) 对数据进行统计分析。使用断口原理评估故障。平均 σ _f值在 2 年的水储存（SC2 和 AP2）后显着降低（p < 0.05），尽管威布尔模量没有差异。所有试样均在氧化锆-水泥粘合剂界面处的粘合区域内粘合失效。
