Abstract:
The adhesion between the titanium and porcelain was evaluated by three-point flexure test. Rutile phase was present on the interface debonded from porcelain. The failure of the titanium-porcelain predominantly occurred at the titanium oxide interface. After being immersed in artificial saliva with pH of 2.7, 5.4, 7.0, and pH 7.0/F(-) 100 ppm, respectively, no decrease of the bonding strength of Ti-porcelain occurred. However, the decrease of bonding strength was about 30%, and 16%, after being immersed in artificial saliva with pH 2.7/F(-) 100 ppm and pH 5.4/F(-) 100 ppm, respectively. While this decrease of adherence for the artificial saliva with pH 2.7/F(-) 100 ppm occurred after an immersion time of only I day, it took about 14 days for the artificial saliva with pH 5.4/F(-) 100 ppm. Immersion in artificial saliva with pH of 2.7, 5.4, and 7.0 did not affect the fracture mode of the titanium-ceramic system. The corrosion of the metal-ceramic interface resulted in the reduction of bonding strength. (C) 2007 Elsevier B.V. All rights reserved.
