Bonding to enamel

Tooth Preparation

1. Bevel enamel surfaces using a diamond bur or clean using an abrasive paste such as pumice powder and water.
   NOTE: Do not use an oil-based paste
2. Remove loose preparation debris by spraying with water.
3. Gently air-dry using 2-3 bursts of oil/water-free air or cotton pellets.

Application

1. Apply 37% phosphoric acid etching gel (e.g. SDI Super Etch) to enamel and leave for 30 seconds.
2. Rinse thoroughly with water and dry with water/oil free air or with cotton pellets. Ensure etched enamel is completely dry.
3. Dispense one or two drops (depending on restoration size) of Bonding Resin into a mixing well. Immediately replace the cap.
4. Apply a thin layer of Bonding Resin to the previously etched enamel surface. Use a light stream of dry, oil-free air to aid the resin flow.
5. Light cure for 20 seconds (460-480nm wavelength, high power LED curing light such as Radii Plus, (SDI Limited)).
6. Place composite such as Aura, Aura Easy or Aura Bulk Fill (SDI Limited) according to manufacturer’s instructions for use.

Bonding layer for the repair of composite

1. Roughen any existing smooth composite resin surface.
2. Dispense one or two drops (depending on restoration size) of Bonding Resin into a mixing well. Immediately replace the cap.
3. Apply a thin layer of Bonding Resin. Use a light stream of dry, oil-free air to aid the resin flow.
4. Light cure for 20 seconds (460-480nm wavelength, high power LED curing light such as Radii Plus SDI Limited).
5. Place composite such as Aura, Aura Easy or Aura Bulk Fill (SDI Limited) according to manufacturer’s instructions for use.
