“…These assumptions explain our experimental results well; i.e., the roughened sodium titanate layer that is formed on titanium metals with NaOH treatment increases the bonding strength of both cpTi and its alloys to the veneering resins, whereas the relatively large granular oxides produced by the alkaline treatment, such as amorphous and rutile TiO 2 on cpTi and CuO on the 12% AuPdAg alloy, have no significant effect on the bonding strength. Although previous results6, 7 suggested that the amount of OH affected bonding, we found no evidence of this.…”

“…In studies of pretreatment methods, Taira et al4, 5 reported the effects of surface oxidation on bonding between titanium and veneering resins. Kikuchi et al6, 7 reported that cpTi heated at 600°C had the most surface OH groups and formed the strongest bond with the veneering resin. Meanwhile, Kokubo et al8–10 demonstrated that alkaline treatment of cpTi accelerated new bone formation in the living body.…”

Commercially pure titanium (cpTi), Ti6Al4V, an experimental ␤-type titanium (Ti 53.4 wt%, Nb 29 wt %, Ta 13 wt %, and Zr 4.6 wt %), and 12%AuPdAg alloy plates were sandblasted, cleaned in water, and dried. cpTi plates were treated with nine alkaline treatments that differed in the type of alkali, alkaline concentration, soaking temperature, soaking time, and heating temperature. cpTi plates that were only sandblasted or sandblasted and oxidized at 600°C for 1 h in air were also prepared. Finally, the bonding strengths of 11 kinds of surface-treated cpTi to resin were measured using a pull-shear bonding method after immersion in physiologic saline solution at 37°C for 24 h. The bonds of the standard alkaline-treated cpTi and two titanium alloys to resins were 1.5-1.9 times stronger than those of sandblasted specimens (p Ͻ 0.01), but no significant effects of the alkaline treatment were observed on the 12% AuPdAg alloy. The greatest bonding strengths were found for cpTi treated with NaOH and KOH and then heated at 600°C (p Ͻ 0.01). In conclusion, alkaline treatment is a simple, effective surface modification of titanium that improves bonding to veneering resin.

Acid Etching of Titanium for Bonding with Veneering Composite Resins

et al. 2006

INTRODUCTIONCommercially pure titanium（cpTi）and its alloys are frequently used for dental prosthetic devices 1） . When they are used to restore anterior teeth, titanium prostheses are generally covered with an esthetic material, such as a composite resin. To obtain good retention between the metal core and resin, retention beads are generally cast on the metal surface to promote mechanical retention -and this form of mechanical retention has the highest survival rate in clinical prostheses 2） . However, a non-mechanical retention method for the metal core is preferred to minimize the removal of sound enamel and dentin when preparing the tooth for cementation. Furthermore, a machining method -versus casting -was developed recently for the fabrication of titanium prostheses. Consequently, there arose an intense, two-pronged effort to develop a new adhesive system that would deliver improved adhesion with the titanium substrate produced by machining. The two key approaches were: focus on the development of adhesion-promoting monomers 3,4） , as well as explore pretreatment methods that would modify the substrate surface for optimal adhesion 5-7） . In the quest for an optimal pretreatment method for titanium, the authors have examined supercritical water 8） and alkaline 9） treatments. Both treatments significantly increased the bond strength of treated titanium to veneering resins.Essentially, these treatments depend on the roughened, tough oxide texture on the surface of treated titanium. However, it was reported 10） that after thermal cycling, the bonding strength decreased remarkably such that the bonding durability was no longer considered sufficient for long-term restorations. On the other hand, the authors have also reported that etching in concentrated H 2 SO 4 at 40 to 90 ℃ produced a highly roughened surface on cpTi and Ti-6Al-4V alloy 11,12） . Therefore, acid etching might be an alternative, effective pretreatment for titanium for the purpose of promoting better bonding to veneering resins.However, acid etching of Ti-6Al-4V alloy provides only adequate dry strength with reportedly poor durability 13）. In this study, therefore, we examined whether etching in concentrated acid enhanced the bond strength durability between cpTi and veneering resin. To this end, we measured the bond strength of acid-etched cpTi to veneering resins before and after thermal cycling, and then discussed the possibility of using acid etching as a pretreatment method for dental restoratives comprising titanium substrate and veneering composite resins. MATERIALS AND METHODS Substrate metalCpTi plates （KS-50, JIS type 2, Kobelco, Kobe, Japan） were used as the substrate. Metal plates measuring 20 × 15 × 1 mm were sandblasted （Hi-Blaster II, Shofu, Kyoto, Japan）with alumina powder（70μm） , cleaned in distilled water supersonically, and dried in air at room temperature. Acid etchingCpTi plates were etched using 11 treatments involving differences in the acid solution （18％ HCl, 43％ H 3 PO 4 , and 4.8 and 48％ H 2 SO 4 ） , soak...

“…Xie et al demonstrated that alkaline media promoted the coordination between 10-MDP and ZrO 2, thereby increasing the strength of the 10-MDP-zirconia bond 9) . Besides, Kikuchi et al showed that alkaline preconditioning might enhance the bond strength between 10-MDP and metal oxide by increasing the amount of -OH ions on the oxide surface [36][37][38] . At the same time, Cilli et al proved that highly alkaline media could cause accelerated degradation of dental composite resin 15) .…”

This study investigated the role played by different pH environments in the deterioration of bonds between Y-TZP and Ti-6Al-4V. One hundred and thirty-five specimens were randomly assigned to one of the following storage media at 37°C: (1) distilled water, pH 6.9, DW; (2) acidic solution, pH 1-2, CS; and (3) alkaline solution, pH 10-11, KS. Shear bond strength (SBS) tests were carried out at the 4-, 14-, and 30-day storage time intervals. The morphology characteristics and elements distribution of the fracture surfaces were analyzed. CS-30 showed the lowest mean SBS and the least amount of residual cement on the Ti-6Al-4V surface after the SBS tests. Bond strength tended to decrease with increasing storage time for the acidic group. Alkaline and neutral media showed little influence on the SBS of Y-TZP to Ti-6Al-4V in 30 days. Acidic environments should be properly avoided to obtain reliable long-term bonding strength between Ti-6Al-4V and Y-TZP.
