Instructions for Use
Description
SR Triplex Hot is a heat-curing, PMMA-based denture base
material for the condensing technique. It offers you ease of
handling and your patients comfort of fit. Additionally, a
veined version of the material is available.
Composition
Powder
Polymethyl methacrylate, Catalyst, Pigments
Liquid
Methyl methacrylate stab., dimethacrylate
Indication
For use in the condensing technique for
– Complete dentures
– Partial dentures
– Combination dentures
– Relining
Contraindication
– Direct intraoral contact of unpolymerized material.
– If the patient is known to be allergic to any of the
ingredients in SR Triplex Hot
Side effects
In individual cases, local allergic reactions to polymethyl
methacrylate materials have been reported.
Application procedure
Isolate boiled-out, well-wetted plaster surfaces with two
layers of Ivoclar Vivadent Separating Fluid and allow to
dry. To ensure an adequate bond with the denture base,
roughen the teeth thoroughly and wet them with
monomer.
Dosage
– Ideal mixing ratio for one denture
23.4 g polymer (powder) : 10 ml monomer (liquid)
– With dosage system
1 denture
nd
Polymer: 2 graduation on measuring cylinder
Monomer: 10 ml
2 dentures
rd
Polymer: 3 graduation on measuring cylinder
Monomer: 20 ml
Integrated dosage system
The integrated dosage system ensures an ideal mixing
ratio and minimum polymerization shrinkage of SR Triplex
Hot. The measuring cylinder for the polymer indicates the
quantity of material required for either one or two
medium-sized dentures. The graduation of the monomer
cylinder is in millilitre.
For ideal dosage, observe the indicated quantities.
Too high a monomer content alters the shade and
handling properties of the material. Additionally,
polymeriza-tion is impaired. This may result in
irritation of the mucous membrane.
Mixing
Thoroughly mix polymer and monomer in the given ratio
with a spatula. Leave to mature in the closed mixing cup
at room temperature (23 °C / 73 °F) for approx. 10
minutes.
Working time
As soon as the material has matured sufficiently and is no
longer sticky, it can be worked for approx. 20 minutes at
23 °C / 73 °F.
Dough time and working time depend on the room
temperature.
Pressing
Place a sufficient quantity of resin dough in the hand-
warm (approx. 40 °C / 104 °F), isolated flask halves.
Carefully close flask, load with 80 bar pressure and fix
with a clamp. Maintain pressure.
Polymerization
Heat-polymerization can be carried out in two ways:
– Standard procedure (recommended method)
Place closed flask in cold water, heat up to 100 °C /
212 °F and let boil for 45 minutes.
– Alternative procedure
Place flask in boiling water. Bring the water to the boil
again and then let boil for 20 minutes.
The alternative procedure is suitable only for
small to medium-sized dentures. Layer
thicknesses must not exceed 1 cm.
The residual monomer content can be reduced by
increasing the polymerization temperature and
extending the polymerization time. We recommend
using the standard procedure to keep residual
monomer at minimum levels. If the standard
procedure is used, the residual monomer content is
< 2.2%.
Cooling
Let the flask cool at room temperature for 30 minutes.
Subsequently, completely cool the flask with cold water.
Deflasking and finishing
Open the completely cooled flask and remove plaster.
