Shear bond strength of composite resin to high performance polymer PEKK according to surface treatments and bonding materials

Abstract

PURPOSEThe object of the present study was to evaluate the shear bonding strength of composite to PEKK by applying several methods of surface treatment associated with various bonding materials.MATERIALS AND METHODSOne hundred and fifty PEKK specimens were assigned randomly to fifteen groups (n = 10) with the combination of three different surface treatments (95% sulfuric acid etching, airborne abrasion with 50 µm alumina, and airborne abrasion with 110 µm silica-coating alumina) and five different bonding materials (Luxatemp Glaze & Bond, Visio.link, All-Bond Universal, Single Bond Universal, and Monobond Plus with Heliobond). After surface treatment, surface roughness and contact angles were examined. Topography modifications after surface treatment were assessed with scanning electron microscopy. Resin composite was mounted on each specimen and then subjected to shear bond strength (SBS) test. SBS data were analyzed statistically using two-way ANOVA, and post-hoc Tukey's test (P<.05).RESULTSRegardless of bonding materials, mechanical surface treatment groups yielded significantly higher shear bonding strength values than chemical surface treatment groups. Unlike other adhesives, MDP and silane containing self-etching universal adhesive (Single Bond Universal) showed an effective shear bonding strength regardless of surface treatment method.CONCLUSIONMechanical surface treatment behaves better in terms of PEKK bonding. In addition, self-etching universal adhesive (Single Bond Universal) can be an alternative bonding material to PEKK irrespective of surface treatment method.

Shear bond strength of veneering composite to high performance polymers

“…In a comparable study, adhesives with multifunctional methacrylates such as Luxatemp Glaze & Bond showed TBS values of 15.0 MPa after 3 days storage and 12.9 MPa after 150 days storage 23) . A study by Lee et al 25) showed SBS values at 14.45 MPa. However, these values were achieved without artificial aging by thermal cycling.…”

“…All previous studies agree that an increase in surface roughness is necessary to achieve better wettability 11,[16][17][18][19] and additional bonding is necessary. Some studies are therefore focusing on different surface treatments 11,[16][17][18][20][21][22][23] and others on bonding agents [23][24][25] to produce a durable bond.…”

Comparison of the Microtensile Bond Strength of a Polyetherketoneketone (PEKK) Tooth Post Cemented with Various Surface Treatments and Various Resin Cements

“…Therefore, both the post-surface treatment and the cement should be appropriately chosen to achieve a durable bond strength when using PEKK as a post material. Few studies have suggested different surface treatment methods to increase the bond strength of PEKK such as the combination of silica coating and an adhesive primer or the combination of air abrasion and an adhesive primer [ 27 , 28 ]. There has been only one study that performed tensile bond strength tests to evaluate the bond strength between PEKK and resin cements [ 28 ].…”

Selective Grafting of Polyamines to Polyether Ether Ketone Surface during Molding and Its Use for Chemical Plating

“…A high adhesion of a metal layer is supported by a micro structure on the surface. This can be realized by plasma etching, chemical etching, laser etching or mechanical etching, e.g., with sandblasting [24][25][26]. There are other processes in use, but all of them require an additional processing step.…”
