Abstract

BACKGROUND

This study evaluated the shear bond strength (SBS) of two different polyetheretherketone (PEEK) and CAD-CAM materials after aging.

METHODS

A total of 42 frameworks were designed and milled from 2 different PEEK discs (Copra Peek, P and BioHPP, B). P and B frameworks were divided into 3 subgroups (n = 7). 14 slices were prepared each from feldspathic ceramic (Vitablocs Mark II, VM), hybrid nanoceramic (Cerasmart, CS), and polymer-infiltrated ceramic (Vita Enamic, VE) blocks. After surface preparations, the slices were cemented to P and B surfaces. The samples were subjected to thermal aging (5000 cycles). SBS of all the samples was measured. Fractured surfaces were examined by SEM/EDX analysis. The Shapiro-Wilk, Two-way Robust ANOVA and Bonferroni correction tests were used to analyze the data (a = .05).

RESULTS

Frameworks, ceramics, and frameworks x ceramics had significant differences (p < 0.05). The highest SBS value was seen in B-VM (p < 0.05). VM offered the highest SBS with both P and B. The differences between P-VM, P-CS, P-VE and B-CS and B-VE were insignificant (p > 0.05). According to EDX analysis, ytterbium and fluorine was seen in B content, unlike P. While VM and CS contained fluorine, barium, and aluminum; sodium and aluminum were observed in the VE structure.

CONCLUSION

Bonding of P and B with VM offers higher SBS. VM, CS and VE did not make any difference in SBS for P, however VM showed a significant difference for B.

摘要

背景

本研究评估了两种不同聚醚醚酮（PEEK）和 CAD-CAM 材料在老化后的剪切结合强度（SBS）。

方法

共设计并铣削了 42 个框架，这些框架由 2 种不同的 PEEK 圆盘（Copra Peek，P 和 BioHPP，B）制成。将 P 和 B 框架分为 3 个亚组（n=7）。从长石陶瓷（Vitablocs Mark II，VM）、混合纳米陶瓷（Cerasmart，CS）和聚合物渗透陶瓷（Vita Enamic，VE）块中各制备 14 个切片。对切片进行表面处理后，将其粘结到 P 和 B 表面。将样品进行热老化（5000 次循环）。测量所有样品的 SBS。通过 SEM/EDX 分析检查断裂表面。使用 Shapiro-Wilk、双向稳健方差分析和 Bonferroni 校正检验对数据进行分析（a=0.05）。

结果

框架、陶瓷和框架 x 陶瓷有显著差异（p<0.05）。在 B-VM 中观察到最高的 SBS 值（p<0.05）。VM 与 P 和 B 均能提供最高的 SBS。P-VM、P-CS、P-VE 和 B-CS 与 B-VE 之间的差异无统计学意义（p>0.05）。根据 EDX 分析，B 中含有钇和氟，而 P 中不含。VM 和 CS 中含有氟、钡和铝；在 VE 结构中观察到钠和铝。
