“…The concentrations of Si and O 2 could belong to the opaque ceramic material. These results are similar to the elemental profiles studied by Suansuwan and Swain [25] who evaluated four bonding systems of porcelain (Titankeramik and Duceratin) bonded to commercially pure titanium and titanium alloy was used.…”

“…The reduction may be related to the solubility of different oxides and this process may be higher in ceramics designed for utilization with cpTi because of the presence of alkaline metallic oxides [35] that was also evident from the failure analysis of this study. Previous studies investigating the adhesion between metal and laboratory resin or metal and ceramics disclosed reduced adhesion after thermal cycling [3,12,25,28,37]. The study of Tróia Jr. et al [28] investigated the same thermal variation and metallic substrate (cpTi) but did not find any influence of thermal cycling on adhesion of ceramic onto this metal.…”

“…The nature of the metal-ceramic union was studied extensively and it is fundamentally based on three mechanisms, namely micromechanical retention, compressive adaptation, chemical union as well as Van der Waals forces [10,16,22]. In this study, the ceramic-gold alloy combination was used as a control group because of its superior physical and chemical properties [25,26]. The feldspathic ceramic-Au-Pd alloy combination presented statistically higher mean values than those of the other two low-fusing ceramic (Super Porcelain Ti-22 and Vita Titankeramik)-cpTi combinations.…”

“…In dental materials research, flexural strength test is considered as the most appropriate method to measure bond strength between two materials 4,10,14,18,19,21,[25][26][27][28] . Some authors would recommend three-point bending test 29,30) , while others would advocate four-point or biaxial flexure strength test to evaluate metal-ceramic adhesion 31) . According to ISO 9693 23) , flexural strength test should be preferred over the other methods because the stresses it simulates closely represent the stresses that occur in dental prostheses with multiples elements.…”

This study evaluated the effects of mechanical and thermal cycling on the flexural strength (ISO 9693) of three brands of ceramics fused to commercially pure titanium (cpTi). Metallic frameworks of 25×3×0.5 mm dimensions (N＝84) were cast in cpTi, followed by 150-μm aluminum oxide airborne particle abrasion at a designated area of the frameworks (8×3 mm). Bonder and opaque ceramic were applied on the frameworks, and then the corresponding ceramic (Triceram, Super Porcelain Ti-22, Vita Titankeramik) was fired onto them (thickness: 1 mm). Half of the specimens from each ceramic-metal combination were randomly tested without aging (only water storage at 37ºC for 24 hours), while the other half were mechanically loaded (20,000 cycles under 10 N load, immersion in distilled water at 37℃) and thermocycled (3,000 cycles, between 5-55℃, dwell time of 13 seconds). After the flexural strength test, failure types were noted. Mechanical and thermal cycling decreased the mean flexural strength values significantly (p<0.05) for all the three ceramic-cpTi combinations tested when compared to the control group. In all the three groups, failure type was exclusively adhesive at the opaque ceramiccpTi interfacial zone with no presence of ceramic on the substrate surface except for a visible oxide layer.

“…The bond strength primarily depends on the mechanical and chemical properties of the interface between the metal and porcelain 9,10) . Although extensive studies have employed different surface treatments of Ti prior to porcelain sintering [11][12][13][14][15][16][17][18][19] , a simple and practical technique to improve Ti-porcelain bond strength has not been well determined, and the underlying mechanism for the bonding of Ti and porcelain is not well understood.…”

INTRODUCTIONTitanium (Ti) tends to react with oxygen at high temperatures, which results in an overly thick oxidization layer. The oxidization layer is located on the Ti surface and influences the bond strength of the Ti-porcelain prosthetic appliance 1,2) . It has been reported that dental porcelain-fused-to-metal (PFM) crowns can be produced with a thinner interfacial oxide layer that effectively promotes the bond between metal and porcelain 3) . Thus, several manufacturers have produced low-fusing dental porcelain that is suitable for sintering onto the Ti surfaces with thinner oxide layers 4) . However, the bond strength between low-temperature porcelain and Ti is only slightly higher than the minimum metal-porcelain bond strength prescribed by ISO 9693 5) . Relevant literature shows that the Ti-porcelain bond strength is still lower than the bond strength between porcelain and other noble or base metals 6,7) . Consequently, there is a need for further investigation to improve the Ti-porcelain bond strength, which may be applicable to PFM dental crowns for long-term clinical application.The strength of the bond between metal and porcelain can be influenced by several factors, including the metal and porcelain chemical compositions, metal surface treatment, porcelain sintering procedure and test method 8) . The bond strength primarily depends on the mechanical and chemical properties of the interface between the metal and porcelain 9,10) . Although extensive studies have employed different surface treatments of Ti prior to porcelain sintering [11][12][13][14][15][16][17][18][19] , a simple and practical technique to improve Ti-porcelain bond strength has not been well determined, and the underlying mechanism for the bonding of Ti and porcelain is not well understood.Chemical solution treatment is a method that can be used to treat and clean metallic surfaces for clinical applications 20) . In industrial fields, an alkaline or acid solution has been successfully employed to clear superficial pollutants from Ti and Ti alloys 21) . Diniz et al. 22) indicated that hydrofluoric acid can serve as an improvement agent and etchant of Ti, thus allowing a higher-quality metallic surface and the removal of pollutants produced during manufacturing. A previous study showed that the Ti surface hardness increases after immersion in a mixed nitric acid/hydrofluoric acid solution such that the Ti-porcelain bond strength is improved 23) . Reyes et al. 8) found that the bonding of Ti and porcelain can be improved by immersing the Ti in hydrochloric acid prior to porcelain sintering. Tróia et al. 12) studied the bond strength between porcelain and cast Ti with different surface chemical treatments. The Ti surface is immersed in acid solution, treated (or not treated) with alkaline solution, and finally sandblasted prior to porcelain sintering. There is no improvement in the Ti-porcelain bond strength when the Ti surface is only immersed in acid solution. The bond strength is enhanced when the Ti surface is first treated w...
