“…Different repair protocols have been developed, and evaluated by researchers, to enhance the functionality, longevity, and esthetics of ceramic restorations: acid etching (e.g., hydrofluoric acid, acidulated phosphate fluoride, and phosphoric acid) 2,[11][12][13][14] , airborne particle abrasion with aluminum oxide 15) , and airborne particle abrasion with silica coating [16][17][18] . However, there is no agreement on which repair system is the efficient one that guarantees favorable clinical outcome 16) . This is because various factors influence the repair bond strength of resin composites to dental ceramics: type of ceramic, repair protocol, aging condition, and type of resin composite 1) .…”

This study evaluated the repair bond strength of a nanohybrid resin composite to a novel CAD/CAM hybrid ceramic based on four intraoral ceramic repair systems. Vita Enamic (VE) CAD/CAM hybrid ceramic was used in this study. Specimens were divided into five test groups according to the repair method performed on the ceramic surface: Gr C (No treatment; control); Gr CZ (Cimara Zircon); Gr PR (Porcelain Repair); Gr CR (Clearfil Repair); and Gr CS (CoJet system). Nanohybrid resin composite (GrandioSO) was packed onto treated ceramic surfaces for adhesion testing using microtensile bond strength test. Debonded specimens were examined with a stereomicroscope and SEM to determine the fracture mode. Data were analyzed using ANOVA and Tukey's HSD test. PR and CZ repair systems significantly enhanced the bond strength of nanohybrid resin composite to VE CAD/CAM hybrid ceramic when compared with the other tested repair systems.

“…The bond strength of resin composite to feldspathic ceramic is higher with HF etching followed by silanization than without [13,14]. An alternative to HF is tribochemical silica coating that is based on labside (Rocatec system, 110 µm, 3M ESPE, St. Paul, MN, USA; ) or charside (CoJet, 30 µm, 3M ESPE) particle deposition methods using silica-coated alumina particles followed by silane application [1,15,16,17]. In the process of tribochemical silica coating, the substrate surface absorbs the kinetic energy of the particle and melts on the surface at 1200°C [18].…”

This study compared the adhesion of metal brackets bonded to different CAD/CAM materials after various surface conditioning methods. CAD/CAM blocks (N=204, n=17 per group) of a) VITA Mark II (VM), b) IPS e.max CAD (IP), c) Lava Ultimate (LU), and d) VITA ENAMIC (VE) were conditioned with one of the following methods: C-Control: (fine diamond bur); CJ: (fine diamond bur+air-abrasion with 30 µm SiO 2 +silane), and HF: (fine diamond bur+9.5% hydrofluoric acid+silane). Metal brackets were bonded to the conditioned surfaces of the specimens, stored in artificial saliva for 24 h at 37°C and thermocycled (x1000). Subsequently, the brackets were debonded under shear in a Universal Testing Machine (1 mm/min). Failure types were analyzed under scanning electron microscope. Data were analyzed using two-way ANOVA and Tukey`s tests (α=0.05). Two-parameter Weibull distribution values, including the Weibull modulus, scale, and shape, were calculated. Mean bond strength (MPa) values were significantly affected by the surface conditioning method (p<0.001) but not the CAD/CAM material type (p=0.052).Bond strengths for all CJ and HF-conditioned specimens were two-fold higher (11.83±1.95 -9.44±1.63) than those for control specimens with all materials (4.73±0.93 -6.02±0.69). Lower mean values were obtained in LU-CJ (9.78±1.61) and LU-HF (9.44±1.63) than those for other groups (11.83±1.95 -10.93±1.33) groups (p<0.05). Weibull distribution showed higher shape values for VM-CJ (11.26) and VM-HF (8.87) than those for other groups (0.82-1.83). In control groups, exclusively adhesive and after conditioning mainly mixed failures were observed. Chairside silica coating or HF conditioning significantly improved metal bracket adhesion to both glassy matrix and hybrid CAD/CAM materials tested, with the most reliable adhesion being observed for feldspathic ceramic.

Background Fracture or chipping are major concerning failures of an all-ceramic restoration. Repairing of the failure restoration using intra-oral technique is time saving and cost effective treatment modality. The present study was proposed to evaluate effect of Er,Cr:YSGG laser irradiation on shear bond strength between zirconia/porcelain and composite resin. Methods Thirty zirconia and thirty zirconia based porcelain disc shape specimens were prepared. Three different surface treatment procedure were applied the specimens. For control groups (Group ZC and PC), instruction manual of an intra-oral porcelain repair system was followed. Different pulse rates of Er,Cr:YSGG laser irradiation (short and long pulses) were applied to zirconia and porcelain surfaces for other groups (Group ZS, ZL, PS, and PL). Porcelain repair kit was used to repair specimens using standard cylindrical teflon mold (2 × 2 mm). Repair bond strength of the repaired specimens was tested using a universal testing machine. Results Highest mean bond strength value was observed at Group PC that was significantly higher than laser applied porcelain groups. Long pulse laser irradiation illustrated that increased mean bond strength compared to short pulse application on to the porcelain surface. Laser applied zirconia groups showed better mean bond strength than Group ZC, but differences between the groups were not statistically significant. Conclusion Different modes of Er,Cr:YSGG laser irradiation enhanced repair bond strength of the composite resin to zirconia, but these were not significant. Following the instruction manual for surface treatment on the porcelain surface was better method than Er,Cr:YSGG laser surface conditioning.
