Abstract

Objectives: To assess the influence of different primer compositions-silane (S), 10-methacryloyloxydecyl dihydrogen phosphate (MDP), and the combination of silane and MDP (S + MDP)-on the bonding performance of MDP-free and MDP-containing resin cements to highly translucent zirconia.

Materials and methods: Tribochemical silica-coated zirconia plates were pretreated with one of three experimental primers, S, MDP, or S + MDP, with untreated specimens serving as controls. Subsequently, these plates were bonded to stainless-steel rods using either two MDP-free or two MDP-containing resin cements. Tensile bond strength was measured after 24 h (TC0) and following thermal cycling (4-60 °C for 10,000 cycles; TC10,000). Data were analyzed using a three-way analysis of variance (ANOVA), followed by one-way ANOVA and Tukey-Kramer post hoc tests (α = 0.05). X-ray photoelectron spectroscopy (XPS) assessed the elemental mass concentrations on the zirconia surfaces.

Results: For MDP-free resin cements, MDP-treated specimens exhibited significantly greater bond strengths than controls, regardless of the aging conditions. However, a significant reduction in bond strength was observed between TC0 and TC10,000 in most of the MDP-free resin cement groups, except for one S + MDP group. Conversely, for MDP-containing resin cements, the S + MDP group exhibited no statistically significant differences between aging conditions. Notably, XPS analysis detected silicon, zirconium, and aluminum on the zirconia surfaces.

Conclusions: No significant difference in tensile bond strength was observed between aging conditions for MDP-containing resin cements bonded to tribochemical silica-coated zirconia primed with S + MDP.

Clinical relevance: The combination of MDP-containing primers and resin cements demonstrated superior bonding performance to tribochemical silica-coated zirconia.

硅烷和 10-甲基丙烯酰氧癸基磷酸二氢酯底漆成分对摩擦化学二氧化硅涂层高透光氧化锆树脂粘接的影响。

目的评估不同底涂成分--硅烷（S）、10-甲基丙烯酰氧癸基磷酸二氢酯（MDP）以及硅烷和 MDP 的组合（S + MDP）--对不含 MDP 和含 MDP 树脂水门汀与高透光氧化锆的粘接性能的影响：用 S、MDP 或 S + MDP 三种实验性引物中的一种对摩擦化学二氧化硅涂层氧化锆板进行预处理，以未经处理的试样作为对照。随后，使用两种不含 MDP 或两种含 MDP 的树脂水泥将这些板材粘接到不锈钢棒上。拉伸粘接强度在 24 小时后（TC0）和热循环后（4-60°C，10,000 个循环；TC10,000）进行测量。数据分析采用三方差分析 (ANOVA)，然后进行单方差分析和 Tukey-Kramer 后验（α = 0.05）。X 射线光电子能谱（XPS）评估了氧化锆表面的元素质量浓度：对于不含 MDP 的树脂水门汀，无论老化条件如何，经过 MDP 处理的试样的粘接强度都明显高于对照组。然而，在 TC0 和 TC10,000 之间，大多数不含 MDP 的树脂水泥组的粘接强度都明显下降，只有一个 S + MDP 组除外。相反，对于含 MDP 的树脂水泥，S + MDP 组在不同老化条件下的差异没有统计学意义。值得注意的是，XPS 分析在氧化锆表面检测到了硅、锆和铝：结论：在使用 S + MDP 打底的摩擦化学二氧化硅涂层氧化锆上粘结的含 MDP 树脂水门汀，其拉伸粘结强度在不同老化条件下没有明显差异：含 MDP 的底漆和树脂水门汀的组合在摩擦生化硅涂层氧化锆上表现出了卓越的粘结性能。
