The purposes of these series are to firmly join denture base resin to metal foundations of removable partial denture with adhesive metal primers.
In this report, the effect of four adhesive metal primers on the shear bond strength of a pour -type denture base resin bonded to silver -palladium-copper-gold alloy was tested. The adhesive metal primers used for this study were METALPRIMER, CESEAD OPAQUE PRIMER, New METACOLOR OPAQUE BONDING LINER, and ACRYL BOND.
The specimens were thermocycled in water for up to 5, 000 cycles at 4to 60°C, and the shear bond strengths were recorded.
The results of the investigation are as follows:
1. The four adhesive metal primers significantly improved the bond strength between base resin and alloy.
2. Sn-plating treatment significantly improved the effectiveness of four adhesive metal primers.
3. The pour-type base resin was bonded most strongly to alloy with CESEAD OPAQUE PRIMER following 50μm alumina sandblasting and Sn-plating after, 5, 000 cycles thermocycling.
4. METALPRIMER was most effective with only alumina sandblasting.
