Instructions for Use
Please read these Instructions for Use care-
fully and familiarize yourself with the use
of the material. Please also refer to the
Operating Instructions of the IvoBase
Injector.
Product description
The IvoBase system consists of a PMMA-based denture
base material and the IvoBase Injector specifically
developed for the material. The system enables fully
automated and shrinkage-compensated polymerization
of dentures.
The IvoBase material combines the advantages of heat-
and auto-curing denture base materials. Even though it is
subject to the requirements placed on auto-curing poly-
mers, it also meets the stricter normative requirements
for heat-curing polymers. IvoBase may thus be
considered a hybrid material. In addition to the conven-
tional hybrid material, IvoBase is also available as an
impact-resistant material version: IvoBase High Impact.
The following shades are available:
– IvoBase Hybrid:
Pink, Pink-V, Preference, Clear, Pink-V Implant,
Preference Implant
– IvoBase High Impact:
Pink, Pink-V, Preference, Pink-V Implant, Preference
Implant, 34-V
Composition
– IvoBase Hybrid
Powder:
Polymethyl methacrylate, softener, initiator, pigments
Liquid:
Methyl methacrylate, dimethacrylate, catalyst
– IvoBase High Impact:
Powder:
High-impact-modified PMMA copolymer, PMMA
copolymer, polymethyl methacrylate, softener,
initiator, pigments

– Repairs
Contraindication
If the patient is known to be allergic to any ingredients.
Intraoral use of unpolymerized material.
Side effects
In individual cases local allergic reactions to methyl
methacrylate materials have been reported.
Safety notes
– Monomer contains methyl methacrylate (MMA)
– MMA is highly flammable and irritating, flash point:
+10 °C/50 °F.
– MMA is irritating to eyes, respiratory organs and
skin.
– Skin contact may cause sensitization.
– Avoid skin contact with monomer and unpoly-
merized material. Commercial medical gloves do not
provide protection against the sensitizing effect of
methacrylates.
– Do not inhale vapours.
– Keep away from sources of ignition – do not smoke.
– Prevent monomer from reaching the sewage system.
– Take measures against electrostatic charge.
Notes on processing
– Thoroughly soak models in water before investment.
– Thoroughly isolate inner flask surfaces before
investment.
– Clean and isolate stone surfaces.
– Closely observe polymerization and cooling times.
– Contact of solvents or monomer with polymerized
denture base material may lead to white
discolouration.
– When using cervical isolations, Ivoclar Vivadent
recommends A-silicones with a hardness of
>65 Shore A (e.g. Flexistone Plus/Virtual
® Heavy
Body Fast). Condensation cross-linking silicones
(C-silicones) may have a damaging effect on the
denture base material.
– The products may only be used and processed by
trained personnel.
– Post-injection of a second capsule of IvoBase or
SR Ivocap ® material into an already filled flask is not
possible.
– The remaining material of an already injected
IvoBase capsule cannot be used again.
– Dried stone must be soaked in water prior to
injection.
– A contaminated flask may lead to smoke
development when heated.
– Store in a humid environment from the
completion of the dentures to their incorporation.
