Apply a fully covering 2

Opaquer layer and precure each segment for 20 seconds.

2

nd

Gingiva opaquer layer

apply the second opaquer layer in such a way that the
retentions are entirely covered with opaquer, i.e. as much
as required and as little as possible. after that, precure the
opaquer for 20 seconds per segment using the the Quick,
immediately mount the restoration on the object holder
(without model), and polymerize it in the Lumamat 100
using Program 2.

Preparing for completion

after polymerization check the degree of curing with a
probe. then, remove the inhibited layer using the
monomer of the corresponding denture base material and
a disposable sponge. this is necessary to prevent streak
formation in the composite while completing the restoration.
make sure that the opaquer shows a slightly shiny surface.
the monomers of cold-curing denture base materials, such
as ProBase

®

cold, are best suited to remove the inhibition

layer.

It is recommended to secure the denture teeth to the
model cast by means of a cold-curing denture base resin
material. Heat polymerization may negatively influence the
bond between the metal framework and the Sr nexco
veneering material.

For the parameters of other polymerization devices, please go to page 57.

When positioning the model casting on the object holder, make sure that enough light can reach them (no

shadow casting). After polymerization, check the curing depth with a probe. If necessary, repeat the
polymerization cycle in a Lumamat 100.
