| Popis: | Objectives The purpose of this study was to evaluate the bond strength of polyetheretherketone (PEEK) to resin-based luting material. Methods Eighty PEEK specimens were randomly divided into two groups ( n = 40/group): no treatment and sandblasting. Each of the 40 specimens of dental gold-silver-palladium alloy (PALLAZ12-n; Yamamoto Precious Metal Co., Ltd., Osaka, Japan), zirconia (Aadva Zirconia; GC, Tokyo, Japan), and hybrid composite resin (CERASMART; GC, Tokyo, Japan) was used as a control material for PEEK. Each group was divided into four subgroups ( n = 10) for the different resin-based luting materials: Panavia ® V5 (Kuraray Medical, Tokyo, Japan), RelyX TM Ultimate Resin Cement (3M ESPE, St Paul, MN, USA), G-CEM Link Force (GC, Tokyo, Japan), and Super-Bond C&B (Sun Medical, Siga, Japan). The resin-based luting materials were bonded onto the specimens. All specimens were stored in distilled water at 37°C for 24h. Bond strength was measured with a shear test, and failure modes were assessed by stereomicroscopy. The surfaces were observed by scanning electron microscopy after the various pretreatments. Results Compared with the control group, the PEEK group showed a significantly lower ( p Conclusions This study found that the bond strength between PEEK and resin-based luting materials was not adequate for clinical use of PEEK. |
