This study investigated the effects of plasma surface treatments and methyl methacrylate-based adhesives on polyetheretherketone. The results showed that applying Visio.link primer significantly increased the bond strengths compared to untreated samples, while different plasma treatments had no significant effect on bonding.
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 polyetherether-ketone-veneering composites. Different plasma treatments without primer application had no significant effect on bonding.
