Encore D/C MiniMix

How To's

1. Isolate the tooth to be prepared. We recommend the use of a rubber dam or cotton rolls.
2. Remove all existing restorations and decay from the tooth. At this time you may place any pins or posts if necessary.
3. Acid etch the entire preparation for 20 seconds using (32% to 40%) phosphoric acid. We recommend the use of Centrix Onyx 40% phosphoric etch gel.
4. Rinse with a water spray for 30 seconds and lightly air dry. The enamel of the preparation should have a frosted appearance.
5. Place bonding system of your choice onto the preparation, according to the manufacturer’s instructions. Do not use one bottle bonding systems. When placing the primer, be sure that all of the solvent has been evaporated and the preparation has a glossy appearance. Before light curing, the bonding agent should be thinned with a light air spray.
6. Build up core
   • Insert Encore D/C Mini-Mix cartridge into a Centrix Snap-Fit Syringe.
   • Remove cap from MiniMix cartridge and attach mixing nozzle.
   • Purge a small amount from the tip to assure proper mixing and flow.
   • Inject the material into the prep, keeping the needle at the bottom of the prep to reduce the chance of voids, fill from the bottom up.

IF USING A MATRIX BAND

1. To facilitate placement, a matrix band may be placed around the prepared tooth.
2. Place the mixing tip directly into the preparation and squeeze the trigger of the applicator gun to express the paste.
3. If a matrix band was used, test with an explorer to insure that material has set prior to removal. Once set, cut and finish the preparation, using water-cooled diamonds or burs.

IF USING A PREFABRICATED CROWN FORM

1. Place the mixing tip directly into the crown form and squeeze the trigger of the cartridge to express the paste.
2. Place the loaded crown form onto the prepared tooth and hold into place until the paste is fully set.

Encore D/C MiniMix core buildup paste has a 1:30 minute working time. The material may be manipulated using a composite instrument. A flat-ended interproximal carver (IPC) is recommended. Light activate with a standard dental halogen lamp or LED curing unit for 40 seconds (per 4mm layer). A thinner layer (<2mm) will need only a 20 second light exposure. To complete the chemical cure activation, wait 5 minutes before cutting and finishing the prep. If a matrix band was used, test with an explorer to insure that material has set prior to its removal. Once set, cut and finish the preparation, using water-cooled diamonds or burs.

PRECAUTIONS

• If pulp is exposed, use a suitable liner.
• Contact with skin and eyes should be avoided. If accidental contact occurs, rinse immediately with plenty of water and consult a physician if necessary.
• Do not use with materials containing eugenol. This could inhibit polymerization.
• Water and oil-contaminated air must be avoided, as they inhibit polymerization at the contact area.
• Avoid contact with gingival tissue and adjacent teeth.
• Placement of any composite is contraindicated if a dry field is not possible.
• Do not use Encore D/C MiniMix core buildup paste for direct application on dentin near the pulp or if the pulp chamber has been exposed.
• There are no known systemic side effects to date, however, do not use in patients with known sensitivities to Bis-GMA, benzoyl peroxide or composite resin materials.
