PLACEMENT OF THE IMPRESSION
Trim all unnecessary parts of the
impression (reflection, palatal
roof) in order to obtain a dental
arch which is as low as possible
but still stable enough.
Note:
Heating of the blade facilitates
trimming of extremely viscous
polyether materials (Impregum,
Permadyne, etc.).
By manipulating the putty rim
and/or cube, the impression is
aligned with the dorsal part of
the impression carrier.
Tip: Place the clear adjustment
plate with inserted pin on the
aligned impression to check the
height of the dental arch. The re-
tention tip of the pin should not
touch the impression (distance:
approx. 3 mm).

Position the impression tray in the
dorsal area on a transversal rim
and in the area of the tray handle
on a cube sized 2 x 2 cm, both out
of Giroform Putty (576461).
Mark the saw cuts and drill holes
for the pins on the impression
material. Each removable seg-
ment has to be furnished with 2
pins (rotation!). Tip: In case of ill
spatial conditions, set only 1 pin
and mill a guidance groove into
the plate.

IMPORTANT:

Plan all adjacent teeth as single
segments since the expansion
of a long row of adjacent teeth
limits the approximal area.
Insert the dove tail of the clear
adjustment plate - with split re-
tention looking upwards - into the
groove of the carrier and guide it
downwards.
Press the impression tray onto the
putty. Make sure that the split re-
tention looks upwards when posi-
tioning the adjustment plate.
Insert the dove tail of the clear
adjustment plate into the groove of
the carrier and guide it downwards
while aligning the impression with
the center line, with the occlusal
plane, and with the vestibular di-
mension of the later dental arch
in relation to the plate size.

To adjust the fixing pressure that
holds the Giroform ® plinth plate in
its place, the allen screw (2.5 mm) is
turned in counter-clockwise direc-
tion to reduce the spring pressure;
if turned in clockwise direction, the
spring pressure increases.
