“…In contrast, the lower bond strengths of the TK groups appear associated with a higher firing temperature, a longer firing time and the non-effect of the bonder application. This assumption was consistent with a previous study, which showed that the TK bonder did not improve the porcelain bond strength to Ti 48) . Accordingly, the high temperature of the firing might progress the excessive oxidation on the Ti surface by the longer firing time.…”

This study evaluated bond strengths of three commercial veneering porcelains to experimental cast titanium-chromium (Ti-Cr) alloy and commercially pure titanium (cp-Ti) via three-point bending test. After the bending test, the fractured specimens were analyzed using an electron probe microanalyzer (EPMA). The Ti-Cr specimens showed lower bond strengths than the cp-Ti specimens, irrespective of the layering porcelain material; however, all the strengths exceeded the minimum requirement of ISO 9693-1:2012 (>25 MPa). EPMA revealed that titanium and/or chromium elements were detected on the debonded porcelain surface of the Ti-Cr and cp-Ti specimens in the case of the higher bond strength. Contrastingly, the residual porcelain was retained on the metallic surface in the case of the lower bond strength. Although porcelain bonding to the titanium alloy is influenced by porcelain type, the Ti-Cr alloy could be feasible for porcelain-fused-to-metal restorations.

“…As far as the chemical bonding at the interface is concerned, in the literature, there is a wide‐ranging debate on the benefits in bonding strength owing to the bonding agents. From the papers that present quantitative results, it is generally postulated that bonding agent increases the bond strength in the case of dental Ti alloys, while there is a small influence (either positive or negative, depending on the specific system) when Co‐Cr casting alloys are used, which is consistent with this study.…”

“…Curtis et al applied bonding agent on dental Ti alloy using different methods (powder, paste, and spray) and observed no increase in metal‐ceramic bond strength compared to specimens with no bonding agent . Hussaini et al examined the effect of bonding agent and surface treatment (no surface treatment, airborne‐particle abrasion, and HCl etching) on the 3‐point bonding strength between a low‐fusing porcelain and commercially pure cast titanium.…”

“…In the particular case of Co‐Cr‐based dental alloys, the manufacturers suggest the application of bonding agent; however, there is poor documentation on the effect of bonding agent in cases of metal‐ceramic prosthetic restorations. Most studies focus on the use of bonding agent in the metal‐ceramic prosthetic restorations of Ti alloys, but very few studies have addressed their effect on Co‐Cr alloys …”

Purpose:To investigate the effect of bonding agent on the bonding strength between Co-Cr dental alloy, prepared by selective laser melting (SLM), and feldspathic porcelain. Materials and Methods:The experiments were conducted according to ISO 9693 and the conventional protocols for the production of metal-ceramic dental restorations. After Al 2 O 3 air-particle abrasion, metal substrates of Co-Cr dental alloy specimens were bonded, using bonding agent (25 specimens), with dental porcelain positioned in layers (opaque, dentin, enamel). Control specimens (25) were also produced without bonding agent. Bonding strength was measured using 3-point bending tests, and the results were statistically analyzed using the t-test and Weibull statistics. Elemental (by SEM/EDS) and crystallographic analyses (by XRD) were conducted on the bonding agent, along cross sections of alloy-porcelain interfaces, and on fracture surfaces. Results: Cohesive fracture occurred (on the porcelain side). The application of the bonding agent decreased the average bonding strength (from 42.27 ± 5.85 to 36.25 ± 3.26 MPa, P = 0.00006), attributed to the nonexisting reaction between the TiO 2rich bonding agent and the Co-Cr alloy, but it increased the Weibull modulus (from 7.84 to 12.16), which reflects the reliability of the bond in the tested metal-ceramic specimens. Conclusions: Although the application of bonding agent slightly decreased the bonding strength, all the measured values of the metal-ceramic specimens produced by the SLM technique, with or without the bonding agent, are markedly higher than the minimum value required by ISO 9693 (25 MPa). Moreover, the use of bonding agent favors the increase of the Weibull modulus.

“…Low-fusing ceramics with compatible thermal expansion coefficients were recommended for the veneering of Ti frameworks (18). The silicon dioxide (SiO 2 ) concentration on the Ti-ceramic interface also affects the Ti-ceramic bond strength (31,32). To obtain the highest concentration of SiO 2 , a ceramic border was applied to the Ti-ceramic interface.…”

Aims: This study determined the effect of three different surface treatment methods [sandblasting (SB), tribochemical silica coating (TSC), and ytterbium fiber laser (YFL) roughening] on surface roughness and titanium-ceramic shear bond strength using specimens obtained using casting (CST), milling (ML) and selective laser melting (SLM). Methods:In this in vitro study, we obtained 32 cylindrical titanium specimens for each fabrication method and subjected them to each surface treatment method. Nine experiments (n=11) were conducted. One specimen was randomly selected from each group for scanning electron microscope analysis. Surface roughness was examined using a profilometer device (n=10). Ceramic was applied to titanium specimens. A universal testing machine was used to determine shear bond strength in megapascal (MPa).Results: Surface roughness of CST/YFL (1.254±0.058 µm), SLM/SB (1.294±0.054 µm), and SLM/ YFL (1.208±0.057 µm) groups were significantly higher than other groups (CST/SB, CST/TSC, ML/SB, ML/TSC, ML/YFL, and SLM/TSC, p<0.01). Shear bond strengths of CST/YFL (20.28±6.97 MPa), SLM/SB (21.9±8.06 MPa), and SLM/YFL (29.92±5.67 MPa) were significantly lower than other groups (p<0.01). Shear bond strength of the ML/SB group (42.40±7.52 MPa) was highest but there were no significant differences between ML/SB and CST/SB (33.04±7.62, p=0.101), CST/TSC (35.38±4.15, p=0.426), ML/TSC (40.03±6.42, p=0.998), ML/YFL (39.43±9.24, p=0.991) and SLM/TSC (37.05±7.84, p=0.766). Conclusions:This study showed that the production and surface treatment method impact shear bond strength. Excessive roughness affects the bonding strength. The highest shear bond strength was identified in the ML group.
