Gingiva opaquer layer
Extrude the desired amount of the ready-to-use opaquer paste from the syringe and spread it out slightly on the mixing
pad using a brush. apply the first opaquer layer (wash) thinly using the brush. If retention beads are used, make sure to
thoroughly smooth out or fill up any roughness on the metal surface, since the wash layer represents the most important
bond between the metal and the composite. Subsequently, precure the wash for 20 seconds per tooth using the Quick.
apply the second opaquer layer. the metal framework should now be entirely covered with opaquer. make sure to apply
as much material as necessary and as little material as possible. Subsequently, polymerize in a Lumamat 100.
Apply the first Gingiva Opaquer layer (wash) thinly with a brush and precure with a Quick curing light.
Entirely cover the gingival area with the second Opaquer layer and polymerize in a Lumamat 100.
– If a metal margin has been designed, thin out the Opaquer towards the metal margin to ensure a clean
transition between metal and composite.
– If a smooth surface is preferred, lightly tap the top of the surface with a spatula.
– Using a probe, check opaquer for complete polymerization in critical areas and cure again as necessary.
