Adhesive bonding of titanium was evaluated with a titanate primer and
adhesive opaque resin. The primer consisted of 2% isopropyl dimethacryloyl
isostearoyl titanate in methyl methacrylate. The adhesive was
4-META/MMA-TBB opaque resin that contained 4-methacryloyloxyethyl
trimellitate anhydride and was initiated by tri-n-butylborane derivative.
Titanium discs were machined and blasted with aluminum oxide. They were
primed and bonded together with the opaque resin. A shear test was
performed after repeated thermocycles for investigation of the durability
of the bond. The shear strength of the primed and 4-META resin-bonded
specimens was 37.2 MPa after 50,000 thermocycles, with only a small
decrease in bond strength. This was significantly higher than the control
values. Thus, titanate primer and 4-META/MMA-TBB opaque resin may be used
for the bonding of titanium in prosthodontic practice.
