LOADING THE PINS INTO THE DRILLED
PLINTH PLATE
EN
Place the Giroform plinth plate,
with split retention looking
downwards, in your hand. Hold
the pins at the retention tip, and
push the tapered part into the
drill hole.
CASTING AND
WORKING
Put the Giroform plinth
plate furnished with pins
on the impression to
check if the plate flatly
rests on the putty.
Spray a separating
agent on the impres-
sion, then rinse it. Mix
super stone in the ap-
propriate mixing ration
and under vacuum.

Tip:
Friction depends on the forces
applied when inserting the pin.
(Push it in with your thumb;
„pricking" indicates that both
playless friction and removable
reposition of the pin are en-
sured.)
Pour the plaster mush
into the impression pre-
venting bubbles (the use
of a vibrator is highly
recommended). When
all teeth and the prepa-
ration area are com-
pletely covered, take
the impression carrier
from the vibrator and
fill the impression above
the brim with plaster.
Cover the MB thread hole in the
center with Giroform putty to
protect it against plaster mush.
Apply plaster on the
pins' retention tips and
on the rest surface of
the plinth plate in the
area where the dental
arch will be located.
Position the plate in
the dove-tail guidance
and lower it into the
plaster mush until the
plate rests planely on
the putty. Important: Do
not apply plaster to the
plate while the vibrator
is on since the pins will
become loose.
Detach after 20 or max.
35 min by removing the
vestibular putty sleeve.
Then, lift off the impres-
sion from the impres-
sion carrier.
