Valplast
Valplast is a flexible denture base resin that
is ideal for partial dentures and unilateral
restorations. The resin is a biocompatible nylon
thermoplastic with unique physical and aesthetic
properties. It allows your patient's natural
tissue tone to appear through the material,
matching the basic shade categories (medium,
light pink, and meharry). Patient's report that
it feels more comfortable because of the
thinness and light weight. It is also guaranteed
for life against breakage when fabricated and
handled according to the manufacturer's
specified procedures.

Valplast Preparation Techniques
Valplast uses the Retento-Grip tissue-bearing
technique for retention. No tooth or
tissue preparation is needed. The dental
laboratory requires only a model poured promptly
and carefully from an alginate impression and a
counter-model. a custom tray is normally
not necessary. A custom bite and try-in
should be taken for accuracy in free-end saddle
cases. The laboratory can usually complete
a unilateral restoration directly from the first
model with the shade and correct bite.
Insertion Techniques for Valplast
After unpacking the case, and immediately prior
to insertion in the patient's mouth, immerse the
case in very hot tap water. Leave the case
in the water for about one minutes. Remove
and allow it to cool just to the point where it
will be tolerated by the patients. Gently
insert the partial in patient's mouth.
The
hot water treatment permits a very smooth
initial insertion and a good adaptation with the
natural tissues in the mouth. If the
patient senses any discomfort because of
the tightness of a clasp, the clasp may be
loosened slightly by immersing that area of the
partial in hot water and bending the clasp
outward. If a clasp requires tightening,
the clasp area may be immerse in hot water and
bent inward to tighten.
If
any reduction is needed due to persistent
irritation, the resin must be handled
differently than acrylic. It is essential
to use a fairly course grinding wheel or a
parallel cut steel bur (vulcanite bur) for
overall reduction. The resin will melt if
there is prolonged contact with a bur or wheel,
therefore it is essential to move the instrument
over the surface continuously.
Minor relief can be made with a rubber wheel or
a vulcanite bur.
If
there are any threads remaining, these can be
removed with a sharp blade. Any roughness
on the surface can be smoothed with a brown
rubber wheel.
The
surface may be repolished after rubberizing (if
needed) using coarse pumice, brown tripoli, and
the Val-Shine polishing compound.
The
grinding tools, Valplast knife, and polishing
agents can all be obtained directly from
Valplast International Corp.
Recommendations for Patient Care
Like
any removable prosthesis, the patient should be
instructed to practice good oral hygiene to
maintain the appearance and cleanliness of the
Valplast restoration. The prosthesis
should be soaked overnight at least three nights
a week in a good denture cleaner. Or, the
patient may immerse the prosthesis in a strong
denture cleaner daily for about 10 - 15 minutes.
It should be rinsed and brushed before
reinserting in the mouth.
