Corrosion resistance of titanium in artificial saliva

      Recently, researchers from Jinhua Hospital of Zhejiang Province published a paper to understand the corrosion resistance of titanium materials in artificial saliva, and provide experimental basis and theoretical basis for clinical selection of suitable dental prosthetic materials. Studies have shown that the acidic environment can accelerate the precipitation of titanium ions and affect the corrosion resistance of titanium materials. The increase in the bonding area of ​​nickel and titanium accelerates the precipitation of titanium ions. It is recommended that patients with nickel allergy should use titanium-nickel dental restorative materials with caution. The article was published in the 2014 issue of the Journal of Medical Research.

Select titanium material, prepare artificial saliva with different pH values ​​of 2.0, 3.0, 5.0, 7.4, respectively, and detect the precipitation of titanium ions in different artificial saliva at 24, 48, 72h; in addition, detect the contact area between titanium material and nickel. The effect on the amount of titanium ions deposited.

The precipitation of titanium ions was pH 2.0>pH 3.0>pH 5.0>pH 7.4, and the precipitation of titanium ions was statistically significant at 72h>48h>24h, pH value 2.0,3.0,5.0 (P<0.05). There was no significant difference in the amount of titanium ion precipitation at different time points under pH 7.4 (P>0.05). In addition, compared with the contact area of ​​titanium and dissimilar metal nickel of 50mm2, the titanium-nickel contact area of ​​100mm2 has a large amount of precipitation, and the difference is statistically significant (P<0.05).
