“…Previous studies which investigated the bonding properties of differently pretreated PEEK specimens showed higher bond values after etching compared with untreated specimens. [25][26][27] While airborne-particle abrasion results in an improvement of the microroughness of the substrate, 20 pretreatment with acids results in an increase of functional carbon-oxygen groups on the superficial layer of PEEK. 27,29 Sulfuric acid attacks the functional ether and carbonyl groups between the benzene rings, while the atomic oxygen (which emerges during the reaction of sulfuric acid and hydrogen peroxide) in piranha acid reacts directly with the benzene ring.…”

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 (SFE) 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, SFE 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°C for either 24 hours or 60 days. Data were analyzed by 4-way and 1-way ANOVA followed by the Scheffé post hoc test and chi-square test (=.05). RESULTS PEEK specimens etched with sulfuric acid resulted in higher SFE 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<.001). PEEK veneered with Sinfony showed significantly higher TBS values than those veneered with VITA VM LC (P<.001). CONCLUSIONS Sufficient TBS for bonding to veneering resin can only be achieved when additional adhesive materials were applied. ABSTRACTStatement of the problem.

“…Based on these excellent physical and biological properties -despite the lack of clinical long-term studies-this composite material seems to be suitable for superstructures in dentistry, i.e. for dental implants, provisional abutments, fixed dental prostheses (FDPs), as well as implant-supported bars and clamps for removable prostheses [15][16][17][18][19] . PEEK represents a high performance thermoplastic polymer within this material group with a low melting temperature of 343°C and can therefore be processed in various ways.…”

OBJECTIVES To test the tensile bond strength (TBS) between two self-adhesive resin composite cements and PEEK after helium plasma treatment and used glycine as a potential coupling agent incorporated in different adhesives. METHODS In summary, 896 air-abraded PEEK specimens were fabricated. Half of the specimens were treated with cold active inert helium plasma and the other half were left non-treated. Both groups were then split in two groups: In group 1 (n=256), 64 specimens were pre-treated with: (a) soft-liner liquid, (b) visio.link, (c) Ambarino P60 and (d) no pre-treatment (control), respectively. In group 2 (n=192), specimens were conditioned accordingly, but the adhesive materials were modified by including a commercially available glycine (Air-Flow PERIO). PEEK specimens were then luted using either RelyX Unicem or Clearfil SA Cement and TBS was measured initially and after 14 days water storage combined with 10'000 thermal cycles (16 specimens/subgroup). Fracture type analysis was performed. For statistical analyses Kolmogorov-Smirnov, Shapiro-Wilk tests, 1-, 4-way ANOVA (post hoc: Scheffé), and t-test were used (p<0.001). RESULTS Helium plasma pre-treatment without glycine showed no impact on initial TBS (p>0.348). In contrast, a combination between glycine application and Softline/Ambarino P60 allowed for significantly higher initial TBS was measured after helium plasma treatment (p=0.001). However, this effect was no evident after thermo-cycling. All groups conditioned with visio.link showed the highest TBS values. SIGNIFICANCE The introduction of amine groups by simple provision of amino acids in the form of glycine can improve the bond strength after helium plasma treatment using different adhesive materials. However, using this simple approach, the method cannot withstand thermal challenge yet.

Polyetheretherketone-A suitable material for fixed dental prostheses?

Abstract: Acid etching should be applied when PEEK is used as substructure material and composite veneering material is applied. In this combination, PEEK might be a suitable material for FDPs, especially in load-bearing areas.
