- Caries removal and removal of old restoration from the tooth should be completed and indirect pulp cap placed (if necessary) prior to build-up.
- Ensure that matrix system or Tofflemire is placed and there is an adequate seal.
- Apply Prelude Primer (Yellow unit dose vial) to entire coronal tooth structure for 15 - 20 seconds with a scrubbing motion. (Rewetting of the brush may be required with primer to adequately cover entire coronal tooth structure based on the area/size).
- Gently air dry tooth with dry air stream (air only unit) for 7-10 seconds to remove water carrier (heavy /strong air blast not recommended) and ensure material is not pooled.
- Apply Prelude Adhesive (Black unit dose vial) to coronal tooth structure for 15-20 seconds. (Rewetting of the brush may be required with adhesive to adequately cover coronal tooth structure).
- Evaporate solvent with gentle dry air stream initially and increase air pressure progressively to thin adhesive and drive ethanol carrier off, do not cure.
- Apply Prelude dual/self cure Link (Red unit dose vial) liberally onto entire coronal tooth structure in a single application, no need to scrub.
- Evaporate solvent with dry air stream for 5 seconds.
- Place and extrude Anchor onto all aspects of the prepared tooth structure. Tip of dispenser should remain in the extruded material while the matrix is filled. Allow Anchor material to self-cure for 3 - 5 minutes. Light penetrates this opaque material very poorly.
- Remove matrix and contour composite appropriately.
- If the buildup is being used as a temporary, check that the occlusion and interproximal contacts are proper.
