Note: Use a rubber dam for isolation.
2. Apply GRADIA PLUS OPAQUE to the prepared metal surface only. The layer applied should have a thickness of
maximum 0.2 mm. Light-cure GRADIA PLUS OPAQUE for 20 seconds.
3. If the surface is still not sufficiently masked, apply a second layer of OPAQUE and light-cure.

4. Repair the restoration by applying a chairside composite material (e.g. G-ænial & Essentia) in layers. Light-cure each
layer according to the manufacturer’s instructions of the respective product
