During waxing, cover the entire base laminate with wax before
finishing. This is so the Pro-flex resin covers the entire laminate to ensure color
and strength in the finished denture. Add any anatomical features like a
rugae, post
dam, etc.
-
While making the bite block, or setting denture teeth, be careful not to damage or burn
the base laminate material.
-
Although Pro-flex resin chemically bonds with acrylic teeth, mechanical retention such as
diatoric holes should be drilled in teeth to ensure optimum retention. This is due
to the flexible nature of the final denture. It is especially true with IPN or
composite teeth.
-
The Waxed Pro-flex denture and base laminate are now invested using standard press
techniques.
-
Boil out flask for five minutes and clean thoroughly with a detergent and hot water.
Rinse with clean hot water.
Note: When boiling out the case, try not to get the laminate base too hot.
If laminate does lose some of its shape after boiling, it usually is not a problem.
The laminate will re-adapt to the model during the packing process.
-
Before applying the separator to the flask, make sure the base laminate is clean, clean,
clean!
-
Apply separator to the flask in the normal manner. Avoid teeth.
-
A bonding agent may be applied to the teeth at this time.
-
Begin to press-pack resin while the flask is still hot. Use cellophane between resin
and laminate until ready for final pack.
Note: Pro-flex resin looks as if it might be hard to pack, but it is not.
When enough resin is in the not flask under pressure, it blends together easily.
-
Trial pack a couple of times to make sure enough resin is in the flask. Remove
cellophane.
-
Before final closing of the flask, wet the hard surface of the base laminate with repair
monomer cleans, etches and makes the surface sticky to ensure a bond between overlay resin
and base laminate. Base laminate should be moistened with monomer to give it a dull
tacky surface. Avoid putting monomer on the soft side.
-
Add a little more Pro-flex resin to the flask to ensure over packing and
a good bond with base laminate.
-
Put the flask in a clamp and heat it in hot water (165 to 175 degrees) for three to five
minutes and press again. Repeat the procedure if necessary until the metal flasks
are closed.
-
Cure for one hour at 165 to 175 degrees F. plus one hour at 200 to 205 degrees F. or eight
hours at 165 to 175 degrees F.
-
At the end of the cure, place the flask in clamp into cold water for 20 minutes to
cool. Then de-flask.
-
Final polish as you would a normal denture. A final high shine can be accomplished
with a buffing wheel, light pressure, and a little water.
Note: Pro-flex dentures should not have to be adjusted due to the flexible
nature of the denture. Warm denture for ease in insertion.
