16. Finishing the dentures
The polymerized IvoBase material is finished with cross-
cut tungsten carbide burs, sandpaper and polishing
media as it is usual for denture base materials.
Repair / relining
IvoBase can be repaired with itself as well as with
ProBase
® Cold auto-curing polymer.
Repair / extension with IvoBase Hybrid /
High Impact
Basically, an IvoBase denture can be repaired without
investment in the IvoBase flask. The basic procedure
corresponds to that used for repairing conventional auto-
curing denture base materials.
Observe the mixing ratio as follows:
Polymer Monomer
IvoBase Hybrid 9 g 5 g
IvoBase High Impact 8 g 5 g
The polymer and monomer must be homogeneously
mixed (for approximately 20 seconds).
Please observe the following processing times (at 23 °C /
73 °F) room temperature):
– Duration of the dough phase: 30 seconds
– Duration of the pouring phase: 1–2 minutes
– Duration of the modelling phase: 3–5 minutes
The maximum total processing time after mixing is
10 minutes.
Polymerize the material in a pressure pot for 20 minutes
at 55 °C / 131 °F at 2.5 bar / 36 psi pressure.
Relining with IvoBase Hybrid / High Impact
The relining of an IvoBase denture may be carried out
with or without investment in the IvoBase flask.
a) Relining without investment in the IvoBase flask
The procedure without investment in the IvoBase
flask is the same as that for relining with conven-
tional auto-curing denture base materials.
b) Relining with investment in the IvoBase flask
Investment and completion for the relining of a den-
ture is basically the same as for the completion of a
waxed-up denture. Make sure that
– the sprues and aeration channels are attached to
the impression of the relining.
– the area to be relined demonstrates a thickness of
at least 2 mm.
Repair / extension relining with ProBase Cold
The procedure corresponds to that used for repairing
conventional auto-curing denture base materials. Please
refer to the ProBase Cold Instructions for Use for details.
