The aim of this study was to investigate the effect of fluoride gel treatment on the
bond strength between composite resin and titanium alloys, and the effect of NaF
solution on the bond strength between composite resin and titanium alloys. Five titanium
and titanium based alloys and one cobalt-chromiun based alloy were tested. Surface of
alloys were treated with three different, methods ; SiC polishing paper (# 2,000),
sandblasting (50 §­ Al2O3), and fluoride gel (F = 1.23 £¥, pH
3.0). After treatment, surface were analyzed by SEM with EDXA. Scotchbond MP and
Superbond C & B were used as bonding agent. Light-curable composite resin (Z100)
was filled into a cylinder- type (5.0 §® ¡¿ 7.3 §®) gelatin capsule. The capsule was
place on the alloy surface treated by various methods, and composite resin was cured
by the visible light for 30 seconds at four different directions. Shear bond strength were
measured by Instron (cross-head speed at 0.02 §¯/min.). From the experiments, the
following results were obtained. Fluoride gel did not affect the surface properties of
cobalt-chromium alloy (VTL) and nickel-titanium alloy, but other titanium alloys were
strongly affected by the fluoride gel. Treatment with the fluoride gel showed similar
bond strength to the sandblasted titanium alloys. Shear bond strength did not show the
significant difference (p>0.05) with treatment time (5 min, 10 min, and 20 min) of
fluoride gel. After ultrasonic cleaning subsequent to the fluoride gel treatment, fluorine
ion or any complex of titanium-flouride were not observed by EDXA. Aging treatments
of the composite resin bonded titanium in NaF solution (1000 ppm, pH 3, 37 ¡É) did not
affect the bond strength between composite resin and titanium alloys.
