by
Step
1. Mix powder and liquid:
Dispense adequate amounts
of powder and liquid into the
respective mixing cups.
Tip: The pipette helps to
dispense the exact amount of
liquid.
7. Repeat the above
procedure to cover the whole
surface with a thin layer of
Pattern Resin LS.
Tip: As fresh Pattern
Resin LS adheres perfectly to
already polymerized material
separate small dots can easily
be connected.
2. Slightly moisten the brush.
Tip: Squeeze out excess
moisture by pressing the tip
of the brush on the inner wall
of the mixing cup. This also
creates a finely pointed tip.
8. Even where high precision
is required, e. g. at primary
crown margins, Pattern
Resin LS exhibits perfect flow
and fit.
3. Pick up a small amount of
Pattern Resin LS powder with
the moist brush.
Due to the material’s
thixotropic properties, a small
resin bead will form on the tip
of the brush.
9. After polymerization of
Pattern Resin LS carefully
remove the pattern to check
the internal surface.
Tip: Small retentions help to
remove the pattern from the
primary crown.
4. The resin bead remains
stable on top of the brush
and is ready e. g. for
modelling of secondary crown
patterns. 10. The inside of the pattern
shows the same glossy
surface as the primary crown.
5. Deposit the resin bead on
the metal surface of a primary
crown.
Working time: 2-3 min
Setting time: 4 min
Tip: No separating agent
is needed on smooth metal
surfaces.
11. Place the pattern back
on the primary crown and
make fine adjustments with
a suitable grinding instrument
(e. g. cross-cut tungsten
carbide).
6. Tip: To clean in between
times - dip the brush into
Pattern Resin LS liquid and
dry with a tissue. 12. Evenly reduce the
thickness of the pattern to
0.3 - 0.4 mm and check
with a calliper. Also check
the margins.
