Abstract

The bonding strength and color reproducibility of titanium-ceramic prosthesis were analyzed the effect according to the surface treatments of titanium and the glazing temperatures of the low fused porcelain. The result of bonding strength compared with respect to the surface treatments was observed that the STB1 group coated by TiN had strongest boding strength and then came the SB1 group used special bonding agent, the SGB1 group coated by gold in that order. The bonding strength by the glazing temperature was indicated that the group with $770^{\circ}C$ of glazing temperature was observed increasing the bonding strength as compared with it of the other group, and the group with $810^{\circ}C$ of glazing temperature was observed to be decreased the bonding strength. Glazing temperature increases, the color by the surface treatment of titanium influenced the color of titanium-ceramic on account of getting higher brightness(${\Delta}L$). As a this result, the SB1 and SGB3 groups was evaluated to has the best color reproducibility.
