Improving the retention of zirconia-based ceramics is desirable in order to avoid the failure of crowns and fixed partial dentures .This can be achieved by creating micromechanical retention using surface treatments. Therefore, it becomes necessary to constantly compare and re-evaluate the influence of different surface treatment methods on the bond strength . To evaluate the effect of four different surface treatments on shear bond strength between zirconia surface and resin cements. Observational study. Twenty five zirconia plate samples were prepared based on ISO standards and were divided into five groups and each group was subjected to following five different surface treatments : no treatment, sandblasting with 110 μm alumina, sandblasting with 250 μm alumina, acid etching with 9.6% hydrofluoric acid and laser radiation on the surface. All the samples were surface disinfected and were embedded in blocks of autopolymerising resin to check shear bond strength on the universal testing machine. Statistical analysis used-data was analyzed using one-way ANOVA and a Post Hoc Bonferroni test. Analysis of the data showed that the highest shear bond strength values were obtained with laser treatment (18.120 ± 0.8159 Mpa). The lowest values were obtained with control group (9.166 ± 0.569 Mpa). Laser treatment increased the shear bond strength values significantly (p<0.05). Surface treatments increased the bond strength between zirconia and resin cement and carbon dioxide laser could be an effective surface treatment for increasing bond strength.

Egyptian Dental Journal
Purpose: To establish an effective bonding for zirconia, the aim of this study was to evaluate the influence of airborne particle abrasion, Piranha acid etching and hot acid etching pre-treatments on bond strength of zirconia with self-adhesive resin cements (Panavia SA, TheraCem) and conventional adhesive resin cement (Panavia F2.0). Also, the effect of Silano-Pen treatment on the bond strength of zirconia to resin cements was evaluated. Materials and Methods: Eighteen zirconia blocks were cut, sintered and divided into three groups (n=6): airborne particle abrasion, Piranha acid etching (3H 2 SO 4 :1H 2 O 2), and hot acid etching (1HNO 3 :1HF). From each group, the bonding surfaces of three zirconia blocks were treated with Silano-Pen. Each zirconia block was bonded to its corresponding composite block utilizing either Panavia SA, TheraCem or Panavia F2.0. Each ceramic ̸ resin ̸ composite assembly was sectioned perpendicular to the bonding interface to obtain microbars of 1 mm 2 thickness. A total of 180 microbars were subjected to 10000 thermal cycles between 5°C and 55°C with dowel time of 30 seconds. Each microbar was subjected to tensile force until de-bonding. The data was statistically analyzed. Results: The hot acid showed the highest µTBS (21.96±5.86 MPa) followed by airborne particle abrasion (16.40±6.23 MPa) and the lowest was Piranha (15.04±7.12 MPa). With Panavia SA, there was significant difference (p=.035) between µTBS with Silano-Pen in airborne particle abrasion and Piranha groups, also there was significant difference (p=.004) between Piranha and hot acid groups. With TheraCem, there was significant difference (p=.008) between µTBS with Silano-Pen in airborne particle abrasion and Piranha groups, also there was significant difference (p=.003) between airborne particle abrasion and hot acid groups. The interaction between cement and Silano-Pen was insignificant (p=.067). Conclusions: Pre-treatment method and type of adhesive resin cement influences the effectiveness of bonding of zirconia. The hot acid etching recorded the highest bond strength, whereas the lowest was recorded with Piranha etching. Silano-Pen treatment after hot acid etching improved the bonding of zirconia to adhesive resin cement. The self-adhesive MDP-containing resin cement (Panavia SA) enhanced the effectiveness of the bond strength with zirconia.

Objective: The aim of this study was to evaluate the effect of different surface treatments; sandblasting, Er:YAG, Nd:YAG, or CO 2 laser irradiation on the shear bond strength (SBS) of zirconia ceramic to dentin. Background data: Zirconia is not properly luted with resin cements. Various surface treatment methods have been suggested for zirconia to obtain high bond strength to resin cements. There is no study that compared the effect of different laser types (Er:YAG, Nd:YAG, CO 2) with sandblasting on SBS between zirconia and dentin. Methods: One hundred and twenty human maxillary third molar teeth were sectioned 3 mm below the occlusal surfaces, embedded in a metal ring with autopolymerizing acrylic resin, and stored in distilled water at 37 0 C. One hundred and twenty disc-shaped zirconia specimens were fabricated (6 mm in diameter and 4 mm in thickness), and randomly assigned to six groups (n = 20): Group 1, untreated (control); Group 2, sandblasted; Group 3, Er:YAG laser irradiated; Group 4, Nd:YAG laser irradiated with contact; Group 5, Nd:YAG laser irradiated with non-contact; Group 6, CO 2 laser irradiated. They were cemented onto the dentin with dual-cured resin cement (Variolink Ò). After they were stored in distilled water at 37 0 C for 24 h, the SBS test was performed at a crosshead speed of 1 mm/min. The fractured specimens were examined under a stereomicroscope to evaluate the fracture pattern. Results: Results of this study did not show statistically significant differences between Groups 1 and 2, or among Groups 3, 4 and 5. The lowest SBS was recorded in Group 6 (CO 2 laser), and the highest SBS was recorded in Group 4 (Nd:YAG laser with contact), followed by Group 3 (Er:YAG laser). The adhesive failure mode was predominantly observed in Groups 2, 3, 5, and 6. Group 1 showed 45% mixed failure and Group 4 showed 50% mixed failure. Conclusions: This study shows that Er:YAG and Nd:YAG laser treatment increased the bond strength of zirconia compared to sandbasting and CO 2 laser treatment.

Successful long-term bonding to zirconia ceramic remains a challenge, requiring special surface treatment methods. The methods used to increasemicromechanical retention to silica based ceramics do not always produce the required roughness and bond strength to zirconia ceramics.The present study was an attempt to improve the bond strength of zirconia-based ceramic restorations (Ice-zirconia-zirkonzahn) to resin cement.twentyone zirconia discs received 3 different surface treatments: group 1-sandblasting with110 um aluminum oxide particles; group 2-silica coating (cojet system) and group 3-laser irradiation (CO 2 laser). The ceramic discs were cemented to natural teeth by resin cement (RelyXUnicem).Scanning electron microscope was also performed to evaluate the surface morphology changes.Shearbond strength was recorded using a universal testing machine at a cross-head speed of 0.5 mm/min and expressed in megapascals(MPa). All groups yielded statistically significantly different roughnessmean values: group 1(219.00 ± 14.8 µm);group 2(187.26 10.72041µm); group 3(262.11 ± 31.675µm) (ANOVA and Newman-Keuls test; p < 0.05). Also, all groups yielded statistically significantly different shear bond strength mean values: group 1(18.69 ± 2.47 MPa); group 2(14.51 ± 1.7 MPa); group 3(12.69 ± 2.439 MPa) (ANOVA and Newman-Keuls test; p < 0.05)
Influence of Surface Treatments on the Bond Strength of Resin Cements to Monolithic Zirconia
The journal of adhesive dentistry
To assess the influence of surface treatment on the microtensile bond strength (μTBS) of resin cements to monolithic zirconia materials. Two types of monolithic zirconia (Zenostar T [ZT] and Prettau Anterior [PA]) were evaluated. The specimens were assigned to three groups based on the surface treatment applied: group 1: control, assintered; group 2: sandblasted with 50-μm Al₂O₃; group 3: tribochemically silica sandblasted. Two types of resin cements (Multilink Speed [MS] and Multilink N [MN]) were applied to each group for evaluating the bond strength using the μTBS test. The fractured specimens were observed with a stereomicroscope and SEM. Surface roughness and topography of monolithic zirconia were examined after treatment. Data were analyzed using ANOVA and Tukey's test. A Weibull analysis was performed on the bond strength data. The bond strength was significantly affected by the surface treatment and the type of resin cement (p < 0.001), but not by the type of monolith...

This study was conducted with the objective of evaluating the effect of three surface conditioning methods on bond strength of resin cement to zirconia reinforced ceramic. The literature was electronically searched in PUBMED, MEDLINE, EMBASE, and SCOPUS to select relevant articles that evaluated the bond strength between zirconia and composite cements. A manual search was performed by scanning the reference lists of included studies. All articles were published online before March 2020, and in English. From electronic database and manual searches, the key word phrases used were zirconia and its bonding with resin cements 439 and surface treatment of zirconia 385 studies were identified 385. N articles with test results met the inclusion criteria and were selected on the resin bond to silica-based ceramics, on the bond to aluminum-oxide ceramics, and 3 on the bond to zirconium-oxide ceramics. Additional references were included to accompany statements of facts. Comparison of the bond strength of the three groups (I, II, III) by one-way ANOVA was done. It was seen that there was a statistically significant difference within the groups (P<0.05) with Group II, that is laboratory silica coating showing the highest mean bond strength (28.23 + 1.53 MPa), followed by Group I that is laboratory grit blasting (20.2 + 2.33 MPa). Group III that is hydrofluoric acid-etching showed the least mean bond strength (10.41 +1.46 MPa).The effect of three surface conditioning methods on the micro tensile bond strength of resin cement to a glass infiltrated zirconia reinforced alumina-based core ceramic was variable. Roughening the ceramic surfaces with air particle abrasion with 110µm Al 2 O 3 followed by coating of silica particle with size of 110 µm SiO 2 and silanization prior to cementation provided higher bond strength when compared with air particle abrasion with 110µm Al 2 O 3 and salinization. Hydrofluoric acid gel used for conditioning the reinforced ceramics showed the least mean shear bond strength.

Background. Bond stability between zirconia and a self-adhesive resin cement is a major concern, and only limited evidence about its longevity is currently available. Moreover, no study has yet comprehensively evaluated the influence of different power levels of the neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser irradiation on the shear bond strength (SBS) of zirconia to a self-adhesive resin cement. Objectives. The aim of this study was to evaluate the SBS of pre-sintered and sintered zirconia to a selfadhesive resin cement after various treatment (air abrasion and the Nd:YAG laser irradiation at varying power levels-1 W, 2 W and 3 W). Material and methods. Ninety-nine zirconia specimens were prepared and divided into 3 groups: control (with no surface treatment); and pre-sintered and sintered groups with surface treatment. Surface treatment was applied before sintering in the pre-sintered group and after sintering in the sintered group. After following all protocols, a resin cement was layered on the zirconia surface. Shear bond strength was measured using a universal testing machine. The results were subjected to the statistical analysis. The surface topography and phase transformation of zirconia were evaluated using the atomic force microscopy (AFM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses after surface treatment. Results. The laser irradiation (3 W, 1 W and 2 W) of the pre-sintered zirconia surface resulted in the highest SBS values (p < 0.001), while the lowest SBS values were obtained with airborne particle abrasion of the pre-sintered and sintered zirconia surfaces. Conclusions. Laser irradiation increased the SBS of pre-sintered zirconia to a resin cement. Surface treatment with air abrasion had a lesser effect on the SBS values.

Introduction: The loss of retention of zirconia-based fixed partial dentures (FPDs) is one of the most frequently reported failures. Objectives: The purpose of this study was to evaluate the shear bond strength (SBS) of four resin cements to zirconia after airborne particle abrasion with alumina of different grades and application of respective primers incorporating organophosphate monomers. Material and methods: The 443 cuboid-shape zirconia specimens (Ceramill Zi; Amann Girrbach AG) were divided into 16 research groups, according to the chemo-mechanical modification: air-abrasion with alumina particles of 50 μm, 110 μm or 250 μm grade, no treatment and application of primers and resin cements: Clearfil Ceramic Primer/Panavia F2.0 (Kuraray Medical), Monobond Plus/Multilink Automix (Ivoclar Vivadent AG), AZ-Primer/ResiCem (Shofu), Z-Prime Plus/Duo-Link (Bisco). After storage in 37 ± 1°C distilled water for 24 hours, the SBS test was conducted (Zwick/Roell Z005; Zwick GmbH&Co.KG) at 1 mm/min crosshead speed to failure. Specimens were subjected to fractographic analysis at ×2.5 and ×35 magnification (Seliga Auctus; Seliga Microscopes Sp.z o.o.; SEM S-4700; Hitachi High-Technologies Corporation). Statistical significance was established with the Wilcoxon signed-rank test and the Kruskal-Wallis one-way analysis of variance (p = 0.05). Results: The highest SBS values of zirconia to resin cement were obtained for Z-Prime Plus/DuoLink (8.24-14.15 MPa) and after 50 μm alumina air-abrasion (6.87-14.15 MPa). However, the alumina particle grade was insignificant. A significant decrease in the SBS was observed for untreated specimens (4.60-8.24 MPa). The failure mode in untreated specimens was mainly adhesive, while in sandblasted it was cohesive and mixed. Conclusions: The chemo-mechanical treatment of zirconia surface before adhesive cementation is crucial to obtain satisfactory values of shear bond strength to resin cements.
Effect of Laser Irradiation on Bond Strength of Zirconia Ceramic to Self-Adhesive Resin Cement
Journal of Islamic Dental Association of IRAN, 2018
Background and Aim: Bonding of zirconia to resin cement is challenging, and the zirconia surface requires surface treatment to yield an acceptable bond strength. This study aimed to evaluate the effect of different surface treatments on the bond strength of zirconia to a resin cement. Materials and Methods: In this in-vitro experimental study, 60 zirconia discs measuring 12 mm in diameter and 2 mm in thickness were randomly divided in to six groups of 10: (I) No treatment, (II) sandblasting plus neodymium-doped yttrium aluminum garnet (Nd:YAG) laser (1 W), (III) sandblasting plus Nd:YAG laser (2 W), (IV) Nd:YAG laser alone (1 W), (V) Nd:YAG laser alone (2 W), and (VI) sandblasting. Using a custom-made punch, a V-shaped bonding area with a 4-mm diameter and 90° angle was created in a Teflon tape. Composite cylinders (Filtek Z250) were then fabricated and bonded to conditioned zirconia ceramic using Clearfil self-adhesive luting cement. Specimens were stored in distilled water at 37°C for 24 hours. Then, the specimens were tested for bond strength using a universal testing machine. Data were analyzed using two-way analysis of variance (ANOVA) followed by t-test. One-way ANOVA and Tukey's HSD (honestly significant difference) test were applied for evaluating the effect of the laser. Results: Sandblasting caused a significantly higher bond strength compared to other methods (P=0.00). Among the laser-irradiated groups, Nd:YAG laser (2 W) yielded a higher bond strength (P<0.05). Conclusion: Sandblasting of high-strength zirconia ceramic can significantly increase its bond strength, but no significant difference in bond strength was noted in the laserirradiated groups.

Aim: to evaluate the shear bond strength of zirconia bonded with two self etch adhesive resin cements PANAVIA F 2.0 and BISTITE ΠDC using two surface treatment techniques: sand blasting and silica coating using Cojet system. Materials and Methods: Twenty rectangular samples with dimensions (14.5×13×3.6mm) and twenty samples with dimensions (7.2×6×3.6mm) were cut from three zirconia ceramic blocks. Sandblasting was done using air blasting machine with 110 µm AL 2 O 3 particles and Silica coating surface treatment was done using Cojet system with 30 µm SiO 2 particles. Half of the small sandblasted zirconia samples were cemented to half the sand blasted large samples using PANAVIA F 2.0 adhesive resin cement and the rest were cemented using BISTITE ΠDC adhesive resin cement. Also, half of the small silica coated zirconia samples were cemented to half the silica coated large samples using both cements. Thermocycling were done for 5000 thermal cycles. The shear bond strength was tested using a computerized universal testing machine. Results: Zirconia specimens cemented with PANAVIA F 2.0 showed higher shear bond strength than specimens cemented with BISTITE ΠDC and the zirconia surfaces treated with silica coating and sand blasting surface treatments. Conclusion: PANAVIA F 2.0 resin cement and silica coating surface treatment could be the best cement and surface treatment for zirconia and sand blasting could be a promising alternative surface treatment.
