Method of Use

Dispense the material from syringe through automix tip. The initial set will occur in 2:00 -2:30( min:sec) with a final set at 3-4 minutes. The cement may also be cured with a dental curing light with a 40 second exposure.

1. Metal to Enamel/Dentin : Metal restorations to tooth structure-crowns, inlays, bridges, and posts including  Maryland and bridges) After try-in, sandblast each side of the restoration. Using a metal primer of your choice, treat the metal exposed to the paste. Clean tooth with non-fluoridated prophy paste or pumice. To prepare tooth for bonding, use a universal dentin / enamel bonding system. Mix equal amount of catalyst and base pastes and use a plastic instrument or injection system to place in restoration. Avoid trapping air bubbles. Seat Restoration on tooth and hold in place until paste reaches initial set (about 2:00- 2:30 minutes). Use a scaler or explorer to remove excess cement immediately upon initial set. It is not important to wait until the final set to remove excess cement.

2. Metal to Metal : Implant prosthesis or crown on post. Sandblast all external metal surfaces to be exposed to paste. Rough intra-oral metal with a micro-etcher or bur. Using a metal primer of your choice, treat the metal exposed to the paste. Clean posts or abutments with non-fluoridated prophy paste or pumice. Mix equal amounts of catalyst and base pastes and use a plastic instrument or injection system to place in restoration. Avoid trapping air bubbles. Seat restoration on tooth and hold in place until paste reaches initial set (about 2:00–2:30 minutes). Use scaler or explorer to remove excess cement immediately upon initial set. It is not important to wait until final set to remove excess cement.
3. Ceramic Restorations to Teeth (Porcelain Veneers, In-lays, On-lays): After try-in, etch ceramic restoration and place in acetone or ethanol in ultrasonic cleaner for 1-2 minutes. Place silanating agent on internal or porcelain restoration. Clear tooth with non-fluoridated prophy paste or pumice. To prepare tooth for bonding, use a universal dentin / enamel bonding system. Mix equal amounts of catalyst and base pastes and use a plastic instrument or injection system to place in Restoration. Avoid trapping air bubbles. Seat restoration on tooth and hold in place until paste reaches initial set (about 2:00-2:30 minute) use scaler or explorer to remove excess cement immediately upon initial set. It is not important to wait until final set to remove excess cement.
