Title
Effect of HTPB-TAC primer on the bond strength of a resin cement to zirconia.
Abstract
Objective: The purpose of this study was to evaluate the effect of
Hydroxyl-terminated polybutadiene grafting with Trimellitic anhydride
chloride (HTPB-TAC) primer on microtensile bond strength of a resin
cement to zirconia ceramics.
Materials and methods: Fully sintered zirconia blocks were primed
with either HTPB-TAC primer or Alloy primer® then bonded to resin
composite block using a resin cement. The blocks bonded with resin
cement without primer served as a negative control. Each cemented
block was cut into 8 microbars (1x1mm). Pool of 48 microbars for each
condition was prepared. Half of microbars in each condition were
investigated with a microtensile bond strength test. The others were
subjected to thermocycling for 10,000 cycles (5 to 55°C) before testing.
Data were analyzed with two-way ANOVA and Games-Howell test at α
= 0.05.
Results: The microtensile bond strength values were significantly
affected by primer and thermocycling without their interaction. The
microtensile bond strength of HTPB-TAC primer and Alloy primer showed
significantly higher bond strength compared to the non-primed specimen
(p<0.05) while those of HTPB-TAC primer had no statistical difference
from Alloy primer (p>0.05). The bond strength of all primers including
non-primer was drastically decreased after thermocycling.
Conclusion: HTPB-TAC primer could promote the bond strength of resin
cement to zirconia.
