“…Specimens were secured in a special holding device as described in detail in a previous study [9]: In short, the resin cements were placed in an acrylic mold (inner diameter: 2.9 mm; D+R Tec, Birmensdorf, Switzerland) with a resin thickness of 1.5 mm and polymerized according to the manufacturer`s instruction. Subsequently, all luted specimens were stored in water for 24 h at 37°C and then randomly allocated to 3 subgroups with respect to different aging levels (n=18): One group was tested immediately after the 24 h of water storage, both other groups were thermally cycled for 5,000 cycles or 10,000 cycles, respectively.…”

“…Unicem to PEEK was used [9]. A sample size of 18 in each group will behave 95% power to detect the decrease by 25% of the mean (4.75 MPa) caused by aging, assuming that the common standard deviation is 3.8 MPa using two group t-test with 0.05 two-sided significance level.…”

“…A first study on this topic assessed the bonding potential of a self-adhesive resin cement (RelyX Unicem) and an adhesive/composite system (Heliobond/Tetric) to differently pre-treated PEEK surfaces. It was show that bonding to PEEK was possible when using a bonding system on an etched surface using sulfuric acid [9]. Another study also indicated that bonding to PEEK can be achieved with composite resin in combination with an adhesive (Heliobond or Clearfil Ceramic Primer) when a self-adhesive resin cement was used [10].…”

“…Both available studies used no artificial aging like thermo-cycling to challenge the bonding performance of dental resins to PEEK [9,10]. In addition -from a clinical perspective -the use of sulfuric acid etching for chair-side PEEK abutment modification seems hazardous and should rather be avoided.…”

OBJECTIVES: The aim of this study is to evaluate the adhesion between PEEK and two selfadhesive resin cements after plasma treatment. METHODS: Eight hundred sixty-four polyetheretherketone (PEEK) disks were cut and polished to silicon carbide (SIC) P4000. One half of the specimens were randomly selected and pretreated with plasma, whereas the remaining 432 specimens remained untreated. Subsequently, specimens were randomly allocated to four groups (n = 108/group): Visio.link (Bredent), Signum PEEK Bond (Heraeus Kulzer), Ambarino P60 (Creamed), and a control group without additional treatment. Half of the specimens of each group (n = 54) were then cemented with either RelyX Unicem Automix 2 (3 M ESPE) or with Clearfil SA (Kuraray). All specimens were stored in water for 24 h (37°C ). Afterwards, specimens were divided into three groups (n = 18) for different aging levels: (1) no aging (baseline measurement), (2) thermal aging for 5,000 cycles (5/55°C), and (3) thermal aging for 10,000 cycles (5/55°C). Thereafter, shear bond strengths (SBS) were measured, and failure types (adhesive, mixed, and cohesive) were assessed. Data were analyzed using descriptive statistics, four-and one-way ANOVA followed by a post hoc Scheffé test (p < 0.05). RESULTS: No adhesion could be established without adhesive pretreatment, irrespectively, whether plasma was applied or not. Also, no bond strength was measured when Ambarino P60 was applied. In contrast, adhesive pretreatment resulted in SBS ranging between 8 and 15 MPa. No significant differences were found between the resin cements used. In general, no cohesive failures were observed. Groups without plasma treatment combined with Visio.link or Signum PEEK Bond showed predominantly mixed failure types. Control groups, plasma treated, or treated using Ambarino P60 groups fractured predominantly adhesively. CONCLUSION: The use of methyl methacrylate (MMA)-based adhesives allows bonding between PEEK and self-adhesive resin cements. Plasma treatment has no impact on bond to resin cements. CLINICAL SIGNIFICANCE: PEEK reconstructions can be cemented using self-adhesive resin cements combined with pretreatment with MMA-based adhesives. Methods: Eight-hundred-and-sixty-four PEEK disks were cut and polished to silicon carbide (SIC) P4000. One half of the specimens was randomly selected and pre-treated with plasma, whereas the remaining 432 specimens remained untreated. Subsequently, specimens were randomly allocated to four groups (n=108/group): Visio.link (Bredent), Signum PEEK Bond (Heraeus Kulzer), Ambarino P60 (Creamed) and a control group without additional treatment. Half of the specimens of each group (n=54) were then cemented with either RelyX Unicem Automix 2 (3M ESPE) or with Clearfil SA (Kuraray).All specimens were storage in water for 24 h (37°C).

“…After the conditioning and adhesive procedures, a transparent, hollow acrylic cylinder with an inner diameter of 2.9 mm and an outer diameter of 3.1 mm was pressed onto the exposed tooth surfaces of the specimen by means of a special bonding device as recently described in detail by SCHMIDLIN et al [19]. A hybrid composite resin (Filtek Supreme XTE ® ; for details see Table 2) was filled into the opening of the cylinder in two increments of about 1-2mm in height, which was lightcured for 40 seconds (Elipar Freelight 2 ® , 3M ESPE ® ; 970 mW/cm 2 ).…”

Objective: This study tested the potential hampering effects of acidic sulfur compounds (ASC) containing hydroxybenzene sulfonic acid, hydroxymethoxybenzene sulfonic acid and sulfuric acid, prior to self-etch and etchand-rinse bonding procedures on enamel and dentin. According to the manufacturer, ASC should be applied after cavity preparation and prior to application of a primer in order to reduce the remaining biofilm in the preparation cavity. Despite promoted marketing, data on the investigated liquid are almost completely lacking. Material and Methods: One-hundred-and-fifty-two extracted mandibular bovine incisors were embedded and polished to expose either enamel (E) or dentin (D). Then, specimenswere randomly divided and conditioned as follows (n=12/group): ASC and consecutive phosphoric acid application (E1/D1), ASC (E2/D2; E5/D5), phosphoric acid (E3/D3) and no conditioning (E4/D4; E6/D6). Groups were then treated with either Optibond FL® (etch-and-rinse; 1-4) or Clearfil SE Bond® (self-etch; 5-6).Hollow acrylic cylinders were bonded with a hybrid composite resin (Filtek Supreme XTE®) to the specimens and the shear bond strength was measured (1mm/min). In addition, failure types were assessed. Descriptive statistics and statistical analyses were performed with one-way ANOVA followed by the Scheffé post-hoc test. Results:For enamel, the highest shear bond strengths values were obtained applying routine bonding procedures (23.5 ± 5.6 MPa for etch-and-rinse and 26.0 ± 6.0 MPa for selfetch respectively). In contrast, dentin pre-treatment with a combination of ASC and phosphoric acid led to the highest shear-bond values (22.8 ± 4.1 MPa). Conclusion:This study shows that ASC prior to dental restoration placement cannot be recommended for etch-and-rinse procedures on enamel, but is appropriate for dentin without interfering with routine bonding procedures. Clinical Relevance:The application of acidic sulfur compounds prior to adhesive restoration placement should be restricted to dentin only as it may negatively influence shear bond strength on sound enamel.
