Abstract:

BACKGROUND: Titanium nitride (TiN) coating and bond porcelain can improve the bonding strength of titanium porcelain.
OBJECTIVE: To investigate the influence of TiN and bond porcelain on the bonding strength of titanium porcelain．
METHODS: Totally 32 cast pure Ti plates were prepared. After sandblasting, the cast plates were divided into four groups: A, B, C and D groups. A: pure Ti group, B: TiN coating group, C: bond porcelain coating group, D: TiN+bond porcelain coating group. And then porcelain was baked at the center of the plates. All plates were submitted to a three-point bending test.
RESULTS AND CONCLUSION: The titanium-porcelain binding stength of the group A was lower than that of the groups B, C and D (P < 0.05).There were no significant differences in the bonding strength among the groups B, C and D (P > 0.05). Titanium porcelain interfaces of groups B, C and D were linked closely together, and there were no obvious pores and bubbles. These findings suggest that the application of the TiN and bond porcelain is helpful to improve the bonding strength of titanium porcelain. If they are handled in two ways simultaneously, the bonding strength of titanium porcelain cannot be improved better.
