Flexible Partial Dentures
Arcari thermoplastic options are ideal for any removable partials, full dentures, unilateral partials, and combination partials with cast metal frames. Recommended for patients with allergies and periodontal problems, our Flexible dentures and partials are monomer-free.
Some of our most popular offerings include:
Valplast allows your patient’s natural tissue tone to appear through the material, matching the basic shade categories (medium pink, light pink and meharry). The Valplast product is guaranteed for life against breakage when fabricated according to the manufacturer’s specific procedures and instructions. Valplast uses the Retento-Grip® tissue-bearing technique for retention. No tooth or tissue preparation is needed.
VisiClear is a clear thermoplastic resin. It is a flexible, strong, stain resistant material for clear clasp application to any type of removable prosthetic.
A dense thermoplastic that is used to create beautiful and durable, partials, temporaries, bridges, clasps and unilaterals providing flexibility with a balance between retention, support and stability.
As an alternative to complete or partial dentures and dental flippers, these flexible removable fixtures look and feel just like natural teeth and fit like a dental veneer or a mouth guard. AcraSmile provides a non-invasive removable prosthetic that can be worn in total comfort – even while eating.
All of our thermoplastic based products are ideal for any removable partials, full dentures and unilateral partials. All of our flexible thermoplastic products are guaranteed against breakage.
Valplast® and similar flexible products are 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.
Valplast and our other flexible products 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.
VALPLAST INSERTION TECHNIQUES
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.
