Abstract

Purpose: To investigate the effects of plasma surface treatments and methyl methacrylate-based adhesives on polyetheretherketone.

Materials and methods: 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.

Results: 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).

Conclusions: 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.

利用等离子体表面改性增强聚醚醚酮基材料的粘合性

目的：研究等离子体表面处理和甲基丙烯酸甲酯基粘合剂对聚醚醚酮的影响：制作了110个聚醚醚酮试样，并将其分为5个预处理组：ArP组，100%氩等离子体；ArOP组，50%氩+50%氧等离子体；ArNP组，50%氩+50%氮等离子体；ArONP组，75%氩+12.5%氧+12.5%氮等离子体；C组，对照组。表面处理后进行了原子力显微镜和扫描电子显微镜检查。表面形貌检查后，在每组一半样品（n = 20）的表面涂上 Visio.link 底漆（Bredent）（n = 10），然后将贴面树脂聚合到聚醚醚酮上。使用万能试验机测量剪切粘接强度：ArP 组和 ArONP 组使用 Visio.link 底漆的平均粘接强度（分别为 13.9 和 13.6 兆帕）明显高于 C 组（9.0 兆帕）。Visio.link 亚组的平均剪切粘接强度高于 Visio.link 亚组（p > 0.05）：结论：使用甲基丙烯酸甲酯基粘合剂（Visiolink）可实现聚醚醚酮-veneering 复合材料之间的粘合。在不使用底漆的情况下，不同的等离子处理方法对粘合效果没有明显影响。

期刊介绍： New materials and applications for adhesion are profoundly changing the way dentistry is delivered. Bonding techniques, which have long been restricted to the tooth hard tissues, enamel, and dentin, have obvious applications in operative and preventive dentistry, as well as in esthetic and pediatric dentistry, prosthodontics, and orthodontics. The current development of adhesive techniques for soft tissues and slow-releasing agents will expand applications to include periodontics and oral surgery. Scientifically sound, peer-reviewed articles explore the latest innovations in these emerging fields.
