– The entire die surface has to be covered with an SR Nexco Liner layer of at least 150 µm. Thin
out the Liner towards the preparation margin.
– Do not separate polymerized SR Nexco Liner from the die.
– If desired, the translucency of the Liners 1–5 may be increased by using Liner clear or Liner
incisal.
Tips and tricks regarding the layering:
Liner incisal may be applied to the marginal area to
facilitate the transmission of light in the cervical area.
this measure provides a harmonious transition between
the gingiva and the restoration.
