This study tested tensile bond strength (TBS) between veneering resins and polyetheretherketone (PEEK) after pre-treatment with adhesive systems. Five-hundred-seventy-six PEEK disks were fabricated, air-abraded and divided into six pre-treatment groups (n=96/group): Z-Prime Plus, Ambarino P60, Monobond Plus, Visio.link, Signum PEEK Bond, and control group without pre-treatment. Each group was divided into three subgroups of different veneering resins (n=32): Sinfony, GC Gradia and VITA VM LC. After specimen preparation with a bond area of 6.6 mm(2), half of each subgroup (n=16) was tested initially, and the other half was thermo-cycled. TBS measurements were analysed by three-way and one-way ANOVA, t-test and Weibull statistics. Groups without pre-treatment and groups pre-treated by Z-Prime Plus and Ambarino P60 showed no TBS. Pre-treatment with Monobond Plus increased the TBS values. The highest TBS before and after thermo-cycling between PEEK and all tested veneering resins was observed for groups pre-treated with Visio.link and Signum PEEK Bond.
本研究测试了在使用粘接系统预处理后，贴面树脂与聚醚醚酮（PEEK）之间的拉伸结合强度（TBS）。制备了 576 个 PEEK 圆盘，进行空气喷砂处理，并分为六组预处理（n=96/组）：Z-Prime Plus、Ambarino P60、Monobond Plus、Visio.link、Signum PEEK Bond 和无预处理对照组。每组又分为三组不同的贴面树脂（n=32）：Sinfony、GC Gradia 和 VITA VM LC。制备粘结面积为 6.6mm(2)的试件后，每组的一半（n=16）进行初始测试，另一半进行热循环。通过三因素和单因素方差分析、t 检验和威布尔统计分析来分析 TBS 测量值。未经预处理以及使用 Z-Prime Plus 和 Ambarino P60 预处理的组没有 TBS。使用 Monobond Plus 预处理会增加 TBS 值。在进行热循环前后，PEEK 与所有测试的贴面树脂之间的 TBS 值最高的是经过 Visio.link 和 Signum PEEK Bond 预处理的组。
