问题陈述。聚醚醚酮（PEEK）可用作固定假牙的框架材料。然而，有关与饰面树脂的持久粘合的信息仍然很少。 目的。本研究的目的是研究 PEEK 化学处理对贴面树脂拉伸粘合强度 (TBS) 的影响，特别强调表面自由能 (SEE) 和表面粗糙度 (SR)。材料和方法。制作750个PEEK样品并分为以下3个预处理组（n=250/组）：用硫酸蚀刻60秒，用食人鱼酸蚀刻30秒，以及未蚀刻的对照。预处理后，通过使用接触角测量和轮廓仪的 SR 来确定 SEE（n=10/组）。用扫描电子显微镜检查预处理的 PEEK 表面的形貌。其余样本（每组 n=240）使用 visio.link 或 Signum PEEK Bond 进行调节，或作为对照组不进行处理。每组中的一半人用 Sinfony 或 VITA VM LC 进行贴面（n=40/组），并在 37°C 的蒸馏水中储存 24 小时或 60 天后测量 TBS。通过 4 向和 1 向 ANOVA 分析数据，然后进行 Scheffe 事后检验和卡方检验 (alpha=.05)。结果。用硫酸蚀刻的 PEEK 样品比未经预处理或用食人鱼酸蚀刻的样品具有更高的 SEE 和 SR。使用硫酸或食人鱼酸蚀刻没有得到关于 TBS 的一般性建议。使用 visio.link 或 Signum PEEK Bond 进行调节可显着提高 TBS (P
Statement of problem. Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses. However, information about the durable bond to veneering resins is still scarce.Purpose. The purpose of this study was to investigate the effect of chemical treatments of PEEK on tensile bond strength (TBS) to veneering resins with special emphasis on surface free energy (SEE) and surface roughness (SR).Material and methods. Seven-hundred fifty PEEK specimens were fabricated and divided into the following 3 pretreatment groups (n=250/group): etching with sulfuric acid for 60 seconds, etching with piranha acid for 30 seconds, and an unetched control. After pretreatment, SEE was determined by using contact angle measurements and SR with a profilometer (n=10/group). The topography of pretreated PEEK surfaces was examined with scanning electron microscopy. Remaining specimens (n=240 per group) were conditioned with visio.link or Signum PEEK Bond, or were left untreated as the control group. Half of each group was veneered with Sinfony or VITA VM LC (n=40/group), and TBS was measured after storage in distilled water at 37 degrees C for either 24 hours or 60 days. Data were analyzed by 4-way and 1-way ANOVA followed by the Scheffe post hoc test and chi-square test (alpha=.05).Results. PEEK specimens etched with sulfuric acid resulted in higher SEE and SR than specimens without pretreatment or etching with piranha acid. Etching with sulfuric acid or piranha acid led to no general recommendations with respect to TBS. Conditioning with visio.link or Signum PEEK Bond significantly increased the TBS (P
