目标.评估通用复合树脂水泥和粘合剂/复合材料系统与不同预处理PEEK表面的粘合潜力。将150个PEEK圆盘嵌入环氧树脂中，抛光（P4000粗砂），并按以下方式处理（n = 30/组）：（A）不处理，（B）用硫酸（98%）酸蚀1分钟，（C）用50 μ m氧化铝喷砂10秒，（D）用110 μ m氧化铝和（E）使用Rocatec系统（3 M ESPE）的二氧化硅涂层喷砂10秒。抛光和喷砂（50 μ m氧化铝）的纯钛（4级）作为对照。用通用复合树脂粘固剂（RelyX Unicem）或未填充树脂（Heliobond）和混合复合材料（Tetric）将丙烯酸空心圆柱体固定到样本上。在剪切试验中测量粘合强度，并评估失效模式。采用单因素方差分析进行统计分析，然后进行事后Scheffe检验和非配对t检验。结果使用通用复合树脂骨水泥，除用硫酸（19.0 +/- 3.4MPa）蚀刻的样本外，在任何PEEK表面上均未建立粘合。与钛的剪切粘结强度显著较低（8.7 +/- 2.8 MPa，p < 0.05）。应用粘合剂/复合材料系统，预处理PEEK的剪切粘合强度值范围为11.5 +/- 3.2 MPa（二氧化硅涂层）至18.2 +/- 5.4 MPa（酸蚀刻），无统计学显著差异（p > 0.05）。在抛光表面上没有获得粘结。当使用粘合系统时，可以粘合到PEEK。除了在蚀刻表面上，用测试的通用复合树脂粘固剂不能实现粘附。这些结果强烈鼓励进一步研究PEEK在牙科中的应用。(C)2010年牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Objectives. To assess the bonding potential of a universal composite resin cement and an adhesive/composite system to differently pre-treated PEEK surfaces.Methods. One hundred and fifty PEEK disks were embedded in epoxy resin, polished (P4000 grit) and treated as follows (n = 30/group): (A) no treatment, (B) acid etching with sulfuric acid (98%) for 1 min, (C) sandblasting for 10 s with 50 mu m alumina, (D) sandblasting for 10 s with 110 mu m alumina and (E) silica coating using the Rocatec system (3M ESPE). Polished and sandblasted (50 mu m alumina) cp titanium (grade 4) served as a control. Acrylic hollow cylinder were either luted with a universal composite resin cement (RelyX Unicem) or an unfilled resin (Heliobond) and a hybrid composite (Tetric) to the specimens. Bond strength was measured in a shear test and failure modes were assessed. Statistic analysis was performed with one-way ANOVA followed by a post hoc Scheffe test and unpaired t-tests. Results. With the universal composite resin cement, no bond could be established on any PEEK surfaces, except specimens etched with sulfuric acid (19.0 +/- 3.4MPa). Shear bond strength to titanium was significantly lower (8.7 +/- 2.8 MPa, p < 0.05). Applying the adhesive/composite system, shear bond strength values on pre-treated PEEK ranged from 11.5 +/- 3.2 MPa (silica coating) to 18.2 +/- 5.4 MPa (acid etched) with no statistically significant differences (p > 0.05). No bond was obtained on the polished surface.Significance. Bonding to PEEK is possible when using a bonding system. No adherence can be achieved with the tested universal composite resin cement except on an etched surface. The results strongly encourage further research in PEEK application in dentistry.
