Practical Procedure
– Framework-fr
ee Restorations (Inlay/Onlay)
2 nd Liner incisal application in the marginal area
after the application of the first Liner layer to the cavity walls and floor, apply Liner incisal in the marginal areas so that all
cavity surfaces are coated with Liner. apply Liner incisal up to the preparation margin in order to ensure a reliable bond
between the preparation margins and the luting composite. this measure helps to reduce premature discolouration
between the restoration margins and tooth structure.
Apply Liner incisal to the marginal areas or the course of the natural enamel and precure each segment for 20 seconds
Thoroughly remove the inhibition layer with clean disposable sponges.
Polymerizing the Liner Appliance Time Program
Precuring time per segment Quick 20 s –
– The entire inner surface of the restoration has to be covered with SR Nexco Liner. The layer
thickness should be at least 150 µm. Thin out the Liner towards the preparation margin.
– Do not separate polymerized SR Nexco Liner from the die.
Removing the inhibition layer after polymerization of the Liner
thoroughly remove the resulting inhibition layer using a
disposable sponge (do not use a solvent); make sure that
the Liner surfaces are free of residue. make sure that the
Liner shows a mat surface.
