“…Adhesive failure patterns have been associated with low values of bond strength, cohesive and mixed patterns seem to be considered more acceptable because they suppose a better infiltration of the resinous cementing agent in the conditioned surface of the PICN. 27,28 In the present investigation, the predominant pattern was mixed for the hydrofluoric acid and self-etching ceramic primer groups, consistent with the highest values of bond strength in the study, and an almost exclusive pattern of adhesive failures for the airborne-particle abrasion group, in which the lowest values were obtained.…”

“…Bond strength can be affected by hydrolytic degradation of the materials in the small adhesive area, storage in water for long periods of time, or thermal cycling. 28,29 Conclusions With the limitations of the present investigation, the self-etching ceramic primer and hydrofluoric acid followed by silane were reported to be statistically equal at 20 and 60 seconds. The 20 second time seems to be a more reasonable option than 60 seconds applying these surface treatments on a PICN.…”

Background: Polymer infiltrated ceramic networks, or hybrid ceramics, are a combination of infiltrating polymerizable organic monomers into a pre-sintered porous ceramic matrix. In addition to having good mechanical properties, the polymer infiltrated ceramic network must comply with the possibility of adequate bonding to the resinous cement. The surface conditioning of this hybrid material must be carefully considered due to its organic composition and ceramic network. The purpose of this research is to evaluate the effect of hydrofluoric acid and a self-etching ceramic primer, under two different application times, on the bond strength of a polymer infiltrated ceramic network. Methods: Blocks of a polymer infiltrated ceramic network were cut to obtain sheets, and these were randomized into five groups. For the group termed AAS, airborne-particle abrasion with Al2O3 (aluminum oxide) of 50µm was used. For groups HF2 and HF6, hydrofluoric acid was used for 20 and 60 seconds respectively, and for the groups MB2 and MB6, a self-etch ceramic primer was applied for 20 and 60 seconds respectively. A silane was applied to the groups AAS, HF2, and HF6 after the treatment. After 24-hour storage in distilled water, a micro-shear bond strength test was performed using a universal mechanical testing machine. All samples were evaluated in a stereomicroscope at 40x and 50x to determine the type of failure. Results: The highest and lowest values of bond strength were reported by groups MB6 and AAS, respectively. Groups HF2, HF6, MB6, and MB2 did not report statistically significant differences. The predominant failure pattern was a mixed failure. Conclusions: With the limitations of the present investigation, the treatments of self-etching ceramic primer and hydrofluoric acid followed by silane were reported to be statistically equal at 20 and 60 seconds.

“…In the present study, HF acid application showed better results considering higher SBS valueseither with conventional silane (13 mpa) or multi-purpose primer (12.6 mpa) and not observed adhesive failure type. This is in line Khaled M Naeim withthe results of Kilinc et al, (2020) (10) who concluded that HF etching was more effective in achieving durable bond strength for glass ceramics. Surface analyses of HF acid-and APF gel-etched porcelain have revealed the production of markedly different etching patterns.…”

“…It produced only a few shallow pores and undercuts, whereas etching with HF acid showed greater roughness and irregularity. (8,10) This can be the reason for significantly decreased SBS value measured when APF gel was used only for 4 min with silane treatment (4.6 mpa) in comparison to HF acid with silane group (13 mpa).…”

Purpose: To evaluate the bond strength to machinable glass ceramic using conventional silane and multipurpose primer after different surface treatments to composite build up. Materials and methods: A total of 64 lithium disilicateIPS e.max CADceramicspecimens with dimension(12Ⅹ10Ⅹ3) were fabricated using milling technology, thespecimens were equally divided into 4 main groups (n=16) according to the method of surface treatment as follows. In Group I: polished, Group II: Acidulated phosphate fluoride (APF) application, Group III: Hydrofluoric acid (HF) application, Group IV:Monobond Etch & Prime (MEP) application. Each main group was further equally subdivided into 2 subgroups (n=8) according to methods of chemical bonding. Subgroup (A):Conventional silane.Subgroup (B):Multipurpose primer.Composite resin cylinder (Master fill) were fabricated and cemented to the treated specimens by multistep adhesive resin cement. All bonded specimens were stored in water bath for 5 months and subjected to 10000 thermal cycles. Shear bond strength (SBS) test was performed afterwards. Scanning Electron Microscope (SEM) was used for specimens examination .Results: The statistical analysis were done using two-way ANOVA and serial one-way ANOVAs followed by Post Hoc Tukey-HSD test at α =(0.05). Application of multipurpose primersignificantly increased SBS (P=0.001). The highest SBS mean value (14.8 ± 2.2 MPa) was obtained for APF followed by Monobond Etch & Prime with conventional silane (14.7 ± 2.8 MPa)On the other hand,APF with conventional silane showed the lowest SBS mean value(4.6 ± 2.0MPa). There was statistically significant difference between polished and APF considering conventional silane and multipurpose primer, and no statistically significant difference was reported between HF and Etch & Prim for conventional silane and multipurpose primer. Conclusions: Multipurpose primershowed superior bond strength in comparison to conventional silanewhen used for conditioning of lithium disilicateIPS e.max CADceramics.

“…In order to calculate the sample size, a previous research performed in 2020 was used as a reference, where it was calculated that 10 specimens per group supplied a power of 0.9. [9] The mean and standard deviation values were calculated for each group in each test. Data were explored for normality using Kolmogorov-Smirnov and Shapiro-Wilk tests, data showed parametric (normal) distribution.…”

Purpose. To assess shear bond strength (SBS) of nanohybrid resin composite used to repair CAD/CAM Hybrid Nanoceramic ceramic after various surface treatments. Materials and Methods. SHOFU HC Hybrid Ceramic disks were sliced to obtain circular-shaped specimens (n= 30). All specimens were thermocycled (5000 thermal cycles), then divided into three groups according to surface treatment performed (sandblasting, HF acid etching, and laser irradiation) (n = 10). Repair with nanohybrid resin composite was performed. SBS values were obtained, and failure modes were determined. Data were statistically analyzed (P ≤ 0.05). Results. The highest SBS mean value was found with (Sandblasting), while the lowest mean value was found with (Laser). There was a statistically significant difference between (Sandblasting), (Hydrofluoric acid) and (Laser) groups where (p=0.001). Statistically significant difference was found between (Sandblasting) and each of (Hydrofluoric acid) and (Laser) groups where (p=0.003) and (p=0.001) respectively, while no statistically significant difference was found between (Hydrofluoric acid) and (Laser) groups where (p=0.291). Conclusion. Surface treatment of the CAD/CAM hybrid nanoceramic material surface with sandblasting before repairing is mandatory to enhance the bond strength with nanohybrid resin composite repairing material. HF acid etching and laser irradiation are alternative surface treatment methods for CAD/CAM hybrid nanoceramic materials.
