LOADING THE PINS INTO THE DRILLED
PLINTH PLATE
Place the Giroform plinth plate,
with split retention looking down-
wards, 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
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 ensu-
red.)
® plinth
Pour the plaster mush
into the impression pre-
venting bubbles (the
use of a vibrator is high-
ly recommended). When
all teeth and the prepa-
ration area are comple-
tely 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 put-
ty. Important: Do not
apply plaster to the pla-
te 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.
