| Manuscript abstract: |
Purpose: to investigate the bond strength of porcelain teeth, with or without surface treatment, to different acrylic base resins.
Matherials and methods: 40 resin specimens with a porcelain tooth divided in four groups: a group made with self-curing resin; the second with warm injection resin; in other two groups porcelain surfaces were sandblasted. Specimens were debonded in an Instron universal machine, with a shear force until pull-out. Results: The warm injection resin specimens were more resistant to detachment than self-curing resin specimens. Sandblasting increased bond strength. Conclusions: The use of sandblasting with aluminium oxide is recommendable to use porcelain teeth. |
