Valplast® Flexible Partial

Valplast® is a flexible denture base resin ideal for partial dentures and unilateral restorations. The resin is a biocompatible nylon thermoplastic with unique physical and aesthetic properties for unlimited design versatility. Valplast® may be used whenever you are considering a removable partial denture for your patient. Its many advantages include retention, comfort, aesthetics, and strength.

Valplast® Flexible Partial
Indications

Valplast is recommended for use as removable partial dentures in place of traditional acrylic saddles on cast metal partials, flippers or stayplates. Valplast and similar flexible products are tissue borne appliances when not used with cast metal partials. Rest seats in are not recommended. Valplast and our other flexible products eliminate the need for invasive procedures.

Contraindications

Valplast should not be used with patients with poor oral hygiene, very short or heavily worn lower anteriors, over a closed vertical dimension or protruding tori. When there is minimal undercut on abutment teeth, metal clasp will be recommended. Our flexible products cannot be relined chairside; appliance needs to be returned to the lab for rebase.

Tech Notes

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 minute. Remove the case from the water and allow it to cool just to the point where the patient will tolerate it. Gently insert the appliance into the mouth.
The hot water treatment permits a 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 immersed 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 coarse 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 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.
Repairing or rebasing can only be done at Arcari. We require the doctor to use a wash material under partial, then do a full pick-up impression and send in with an opposing model and a bite. Re-basing is pressure induced.
