To examine the effects of anodization and different surface modifications of titanium on bond strength to 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) resin cement.
Grade 5 titanium alloy disks (n = 160) were assigned to one of five prebonding surface treatment study groups (polished; polished and anodized; polished, etched, and anodized; sandblasted; sandblasted and anodized). Disks were adhesively bonded with 10-MDP resin cement (Panavia 21; bonding area: 3.3 mm in diameter) to composite resin cylinders. In each study group, tensile bond strength tests were conducted after 24 ± 1 hours and after 6 months (180 ± 2 days) of water storage (n = 16 specimens per water storage subgroup). Debonded specimens were stereomicroscopically analyzed to determine their fracture mode. Statistics included one-way and multifactorial ANOVA and Tukey post hoc tests (α = .05).
Anodization and water storage did not significantly (P ≥ .389) affect tensile bond strength. Although subgroups of polished samples had significantly (P ≤ .031) lower bond strengths (subgroup mean values: 20 to 26 MPa) than etched or sandblasted samples (subgroup mean values: 29 to 33 MPa), they nonetheless exceeded the empirical threshold of 10 MPa used as a criterion for clinical recommendation. The fracture mode of all test specimens was predominantly cohesive.
Anodization of titanium surfaces can be performed without weakening the adhesion of 10-MDP-based resin cement to titanium.
研究阳极氧化和钛表面不同处理对 10-甲氧基癸基二氢磷酸酯（10-MDP）树脂水门汀粘结强度的影响。
将 5 级钛合金圆盘（n = 160）分为 5 个预粘结表面处理研究组（抛光组；抛光和阳极氧化组；抛光、蚀刻和阳极氧化组；喷砂组；喷砂和阳极氧化组）。用 10-MDP 树脂水门汀（Panavia 21；粘结面积：3.3mm 直径）将圆盘与复合树脂圆柱体粘结。在每组研究中，分别在 24±1 小时和水储存 6 个月（180±2 天）后（每组水储存亚组 16 个标本）进行拉伸粘结强度测试。用立体显微镜对离断的标本进行分析，以确定其断裂模式。统计学分析采用单因素和多因素方差分析及 Tukey 事后检验（α =.05）。
阳极氧化和水储存对拉伸粘结强度没有显著影响（P≥.389）。尽管抛光样本亚组的粘结强度明显（P≤.031）低于蚀刻或喷砂样本亚组（亚组平均值：20 至 26 MPa），但仍超过了作为临床推荐标准的 10 MPa 经验阈值。所有测试标本的断裂模式均主要为内聚性断裂。
在不削弱基于 10-MDP 的树脂水门汀与钛之间粘结强度的情况下，可以对钛表面进行阳极氧化处理。
