Instructions for Use
Contraindication
– Direct intraoral contact of unpolymerized material.
– If the patient is known to be allergic to any of the
components listed.
Product description
The SR Ivocap System is an injection technique, which has been
especially developed to compensate curing shrinkage.
Heat/pressure curing allows shrinkage of the acrylate during
polymerization to be compensated by inflowing material.
The SR Ivocap injection technique, therefore, permits the
fabrication of high quality products with excellent physical properties.
– Do not wet teeth with SR Ivocap monomer, as this will
weaken the bond to the tooth
– Soak models thoroughly before the investment
– Thoroughly isolate inner flask surfaces before the
investment
– Injection channels must have a diameter of 3–5 mm
– Thoroughly clean and isolate stone surfaces
– Observe polymerization and cooling times precisely
– Contact of solvents or monomer with the polymerized
denture base material can cause white discolouration
– If cervical areas have to be isolated when the SR Ivocap
procedure is used, Ivoclar Vivadent recommends Sil-Tech
Super. Other products may cause unfavourable reactions in
the denture base material.
Warnings
– The monomer contains methyl methacrylate (MMA)
– MMA is highly flammable and irritating –
flash point +10 ºC / 50 ºF
– MMA irritates the eyes, respiratory organs and skin
– Contact may evoke sensitive skin reaction.
– Avoid prolonged or repeated contact of skin with
monomer and unpolymerized material. Commercial medi-
cal gloves do not provide protection against the sensitizing
effect of methacrylates.
– Do not inhale vapours
– Keep the material away from sources of heat – do not
smoke
– Do not dispose of the monomer in the drainage system
– Avoid electrostatic charging
Step-by-step procedure
Investment (lower flask half)
Place the investment aid (1) in the flask, mix the stone
and invest the thoroughly water-soaked model. Remove
excess stone from the thermal insulating component (2)
and the flask edges.
Placing the funnel
Remove the investment aid after the stone has set and
position the injection funnel (3) and the funnel (4) in its
place.
Injection channels
For complete upper dentures, one injection channel is
sufficient, fanning out from the funnel tip towards the
palate (Fig 3a). In the case of complete lower dentures,
two channels to the dorsal extremities of the dentures are
to be supplied (Fig 3b). For cast metal frameworks with
individual extension bases, either each base must be
®

provided with a channel at the distal end or an inter-

connecting ring channel (dotted line) can be fabricated
(Fig 3c).
Prior to investing the antagonist part, the injection channels are
formed with pink wax. This can also be done after boil-out or
before isolating by simply milling them in.
– Injection channels must have a diameter of
3–5 mm
– Choose the shortest path
– Make sure not to damage the investment edges
along the injection funnel; they form a seal
towards the posterior shoulder of the flask.
Investment (upper flask half)
Place the upper flask half on the lower one after isolating
it with Vaseline or Ivoclar Vivadent Separating Fluid. Mix
the plaster and pour over teeth, avoiding the formation of
bubbles, until the incisal and occlusal areas are lightly
covered.
To make deflasking easier, apply a paper insert as a
separation layer (the insert should be moistened with
water).
Then, fill the flask to the brim, put on the cover and completely
press down by hand.
Do not close the flask with a press!
Boil-out procedure
Preheat the flask in very hot water for at least
5 minutes. Remove wax and thoroughly boil out with hot
and clean water. Allow the flask halves to cool to room
temperature. Remove adhering plaster residue from the
flask edges and thermal insulation component.
Isolation
Isolate the still moist plaster surfaces twice with Ivoclar
Vivadent Separating Fluid. Separating with a suitable
spray gun is also possible. Avoid pooling, eg in the
gingivobuccal fold or interdental areas. Do not rinse
isolated areas with water.
Capsule preparation
Contents of capsule: 20 g polymer, 30 ml monomer
a) Remove monomer container from the capsule and
break open by twisting off the sealing cap.
b) Pour the monomer into the capsule.
c) Re-insert the monomer container into the capsule base
prior to mixing.
Start mixing immediately following the addition of the
monomer (5 min in the Cap Vibrator).
d) Mount the capsule in the Cap Vibrator, secure it with a
rubber band and mix for 5 minutes.
The SR Ivocap denture base material should form a ball in the
process. If this is not the case after 5 minutes of mixing, the
material can be mixed for an additional 30 seconds. The failure
of the material to form a ball does not influence the quality of
the denture base material.
Do not mix longer than 7 minutes, as the resin may
become too warm, which increases the risk of premature
polymerization.
e) Remove the empty monomer container, eg with
compressed air, place the capsule on the capsule plunger
and press the contents upward with light rocking
movements. Allow air to escape through the capsule
opening.
There should be no air between the plunger and the
contents. Previously mixed capsules can be
refrigerated in the dark for 5 days. Allow them to
regain room temperature before reuse.
Clamping of the flask
Place the injection funnel with the inserted funnel in the
lower flask half. Carefully bring together the two flask halves and ensure the correct fit of the flask lids.
Then, completely insert the flask into the clamping frame. Apply
3 tons / 6000 lbs pressure to the clamping frame with the flask
in a hydraulic press (corresponds to about 80 bar / 1133 psi
hydraulic pressure). At the same time, push the ratchet (B1) on
the clamping frame to the right. After that, cease applying pressure and remove the clamping frame with the flask from the
press.
Inserting the SR Ivocap capsules
Remove the cover from the capsule and fully insert the
capsule into the flask.
Mounting the pressure apparatus
Fully extend the plunger of the pressure apparatus, eg by
pulling the piston rod when the compressed air locking
valve is open.
Place the SR Ivocap pressure apparatus on the flask, lift the
safety loop (A1) and press the plunger into the capsule until
the vise shanks are correctly positioned on the flask. Then, pull
down the safety loop until it snaps into place.
Injection
Connect the pressure apparatus with the compressed air
locking valve closed to the compressed air supply (6 bar /
85 psi). Slowly open the locking valve. The plunger will
descend and press the SR Ivocap material into the mould.
– SR Ivocap material which is left over or which has
been in a mixed state for some time requires a longer injection time of 10 minutes.
– Allow leftover material to regain room temperature
before use.
– When the red ring on the piston rod becomes
visible during injection, mix a new capsule and
replace the empty one.
Polymerization
Place the SR Ivocap assembly in a suitable polymerization
bath. The surface of the water should be covered with plastic floaters in order to prevent unnecessary loss of heat
(isolation). When immersing the SR Ivocap assembly in the
polymerization bath, make sure that no plastic
floaters are trapped beneath the clamping frame.
3
– The temperature of the water bath must be set in such a
191817
16
way that the water boils during the entire polymerization
period.
– The water level must reach the red mark on the clamping
frame and must be maintained at this level throughout the
polymeri zation period.
– The polymerization time once the water starts to boil is
exactly 35 minutes.
– Do not interrupt the boiling procedure by introducing other
flasks.
– Content of residual monomer according to ISO 20795-1
< 2.2%. In order to reduce the content of residual
monomer below 1%, the material must be polymerized for
90 minutes in boiling water. The residual material will set in
the capsule during this time.
Consequences of incorrect water level during
polymerization
– Over the red mark
– Capsule reservoir polymerizes; constant flow of the resin
during polymerization becomes impossible.
– Waste of material due to polymerization of leftover
material in the capsule.
– Below the red mark
– Partially unpolymerized areas in palatal, post dam or
retromolar areas
Cooling
After completion of the 35-minute polymerization
procedure, remove the SR Ivocap assembly from the
boiling water and immediately cool in cold water.
During the first 20 minutes of the cooling phase, the
pressure in the clamping frame and the injection
apparatus must remain unchanged.
After 20 minutes, the pressure apparatus can be removed. The
clamping frame together with the flask, however, must remain
in cold water for an additional 10 minutes.
Total cooling time: 30 minutes
A locking valve on the pressure apparatus maintains the
injection pressure at a constant level during the cooling
phase, irrespective of the compressed air supply. This
results in increased mobility, since the cooling bath does
not necessarily have to be near the air supply.
Deflasking
Mount the clamping frame in the press and re-apply 3 tons /
6000 lbs pressure. Move the ratchet (B1) back to the left
and release pressure. Remove the flask from the clamping
frame.
Recommended procedure
– Remove both plastic covers, insert flask with the narrow
side to the front into the press. Place any suitable object
between the plaster investment and the pressing plate, not
touching the flask edges. Close the press with minimal
pressure (Fig 19).
– Introduce a broad screwdriver into the joint beside the
guide piece and lever the upper flask half upwards (Fig 19).
– Remove the flask from the press and repeat the same
procedure with the flask reversed. The investment can now
be removed from the flask without difficulty and without
using force (eg hammer).
– Remove plaster in the usual way.
– Finish and polish as usual.
– Deflasking devices can also be used for this purpose.
