Objectives. This study compared the shear bond strength (SBS) between veneering composites and titanium (grade 1), a cobalt–chromium-alloy and a high precious-alloy, which were pretreated using silicoating systems, functional monomers or an experimental titanium-dioxide coating system.
Method. The specimens were sized to rectangular plates of 20×10×2
mm
3 (
l,
w,
h) and a composite cylinder (height of 4
mm, diameter 5
mm) was axially polymerized to the middle of the plates. After aging (24
h or 150
d storage in distilled water at 37
°C, or thermal-cycling: 6000×5°/55
°C) the SBS was determined.
Results. Independent of the type of metal and the conditioning/coating techniques the lowest SBSs were found after thermal-cycling.
Titanium. The SBS of the silica coating systems and the functional monomers did not differ statistically on titanium. However, the titanium-dioxide coating method had significantly higher values than the other methods.
Cobalt–chromium. The highest mean values were observed with the titanium-dioxide coating system and the phosphate acid ester.
Precious alloy. No statistical significant different SBS was found for the silicoating and the titanium-dioxide coating methods, while the functional monomers were statistically significant (lower) different to both systems.
Conclusion. Generally, the titanium-dioxide coating system achieved the highest SBS under different aging conditions and on all three different metal-surfaces.
