Sealing the model
Isolate all areas of the model which come into
contact with Sr nexco prior to the dentin and incisal
layering. this step helps to prevent the lab composite from
sticking to the model. Use Sr model Separator to seal
adjoining parts of the model (e.g. stone die and pontic
rests). apply Sr model Separator in a thin layer, allow to
react for a short time, and remove excess with oil-free
compressed air.
Removal of the inhibition layer
thoroughly remove the resulting opaquer inhibition layer
using a disposable sponge (do not use a solvent); make
sure that the opaquer surfaces are free of residue. make
sure that the opaquer shows a slightly shiny surface.
Tip
Characterizing the Opaquer
after the inhibition layer has been removed, you may
individualize/modify the shade of sections of the opaquer
surface with Sr nexco Stains. It is advisable to apply a
thin layer of Stains in the marginal and inter dental area,
particularly if space is limited, to enhance the in-depth
shade effect. Subsequently, precure Sr nexco Stains for
20 seconds using the Quick.
