Casting the counter model

System Short Instructions

– Isolate the inner surfaces with

a thin layer of petroleum jelly

– Place access former "half"

and flask lid in the flask half

– Position the filter wax

component

Mandibular complete dentures

– Place injection channels to the

lingual area of the retromolar
triangle

– Separate the center channel

– Soak model in water, isolate,

and invest in dental stone
(Class III)

– Access former "half" must be

invested flush in the stone

– Press the aeration wax

component anterior to the

contouring and to the center
of the filter wax component

– Allow the stone to set

thoroughly

– Remove access former "half"

and place access former

"full"

Partial dentures

– Place an injection channel at

the dorsal end of each
denture saddle

– Place an aeration channel

anterior to the denture saddle

– Position the injection wax

component on the

contouring, stone surface and
access former and press on

– Coat the surfaces of the

contoured dentures with

A-silicone

– Do not cover access formers,

occlusal surfaces and incisal
edges

– Provide the silicone with

retentive patterns

Maxillary complete dentures

– Press one injection channel

against the center of the
palatal roof

– Place one channel each

vestibular to the two maxillary
tubers and press on

– Isolate stone-to-stone contact

surfaces with Separating Fluid

– Position the upper flask half

and lock using the locking
clasps

Boil out the model

Preparing for injection

3

– Mix conventional dental stone

(Class III) and have it flow into

the flask without any bubbles
– Skim off excess stone
– Allow the stone to set

thoroughly
– Heat in a water bath at 90 °C

for 5-8 min

– Open the flask, remove access

former "full" and roughly
remove wax using a wax knife

– Boil out the inner surfaces

with clean, boiling water

– Use pure water without any

additives

– Roughen basal and cervical

surfaces of the resin teeth

– Allow flask halves to cool to

below 30 °C and check

temperature with an IR
thermometer

– Isolate stone surface with

Separating Fluid

– Apply a second coat after

5 minutes

– Insert the aeration filter

flush into the corresponding
recess in the flask

– Push the IvoBase funnel into

the centering insert until it
stops and position it

– Assemble the two flask halves

and lock

expansion phase

– Pour the monomer into the

open capsule

– Remove the flask at the end

of the program

– Cool in cold water for

15 min.
– Remove the locking clasps
– Secure the flask in the dental

press with the divesting aid

– Use the spatula to mix the

monomer and polymer in the
capsule to a homogeneous

mixture for approx. 20–30 s

– Lift the upper flask half by

levering it on both sides in the

gap between the flask halves
– Turn over the flask
– Repeat the procedure

– Place capsule on an even

surface

– Place flask with the centering

insert on the capsule
