To investigate the effects of plasma surface treatments and methyl methacrylate-based adhesives on polyetheretherketone.
One hundred ten polyetheretherketone specimens were fabricated and divided into five pretreatment groups: group ArP, 100% argon plasma; group ArOP, 50% argon + 50% oxygen plasma; group ArNP, 50% argon + 50% nitrogen plasma; group ArONP, 75% argon + 12.5% oxygen + 12.5% nitrogen plasma; group C, control. Atomic force microscopy and scanning electron microscopy were performed after surface treatments. After topographical surface examinations, Visio.link primer (Bredent) (n = 10) was applied to the surface of half of the samples in each group (n = 20) and the veneering resin was polymerized onto the polyetheretherketone. The shear bond strengths were measured using a universal test machine.
The mean bond strengths of the Visio.link primer applied to group ArP and group ArONP (13.9 and 13.6 MPa, respectively) were statistically significantly higher than that of group C (9.0 MPa). The average shear bond strength of the Visio.link subgroups was higher than that of the Visio.link subgroups (p > 0.05).
The use of a methyl methacrylate-based adhesive (Visiolink) provides bonding between polyetheretherketone-veneering composites. Different plasma treatments without primer application had no significant effect on bonding.
研究等离子体表面处理和甲基丙烯酸甲酯基胶粘剂对聚醚醚酮的影响。
制作了 110 个聚醚醚酮标本,并分为五组预处理:组 ArP,100%氩等离子体;组 ArOP,50%氩+50%氧等离子体;组 ArNP,50%氩+50%氮等离子体;组 ArONP,75%氩+12.5%氧+12.5%氮等离子体;组 C,对照组。表面处理后进行原子力显微镜和扫描电子显微镜检查。形貌表面检查后,将 Visio.link 底胶(Bredent)(n=10)应用于每组(n=20)的一半样本表面,并将贴面树脂聚合到聚醚醚酮上。使用万能试验机测量剪切结合强度。
涂有 Visio.link 底胶的 ArP 组和 ArONP 组(分别为 13.9 和 13.6 MPa)的平均结合强度明显高于 C 组(9.0 MPa)。Visio.link 亚组的平均剪切结合强度高于 Visio.link 亚组(p>0.05)。
使用甲基丙烯酸甲酯基胶粘剂(Visiolink)可提供聚醚醚酮-贴面复合材料之间的粘结。未使用底漆的不同等离子体处理对粘结没有显著影响。
