Clinical Indications

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

Contraindications

  • Valplast partial dentures 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.
  • Valplast partial dentures cannot be relined chairside; appliance needs to be returned to the lab for rebase.
  • On distal free-end saddles.

Preparation Requirements

Valplast uses a unique tissue bearing technique for retention for which no tooth or tissue preparation is needed. Your Certified Valplast Laboratory requires only a model poured promptly from an alginate impression and counter-model. A wax try-in is suggested prior to completion of the case. Special abrasives and techniques will allow you to make adjustments and fine tune the fit of any Valplast® partial just as you would with acrylic. Follow these simple instructions to ensure success when working with your next Valplast® case.
  • Start with an accurate bite registration and void-free impression using a custom tray.
  • No tooth or tissue preparation is needed.
  • Send a master cast poured from an alginate impression along with opposing model and bite registration.
Impression
  • The best type of impression material to use is alginate.
  • The powder should be gently stirred from the bottom of the container to the top to redistribute the heavier elements that control shrinkage in the impression.
  • The model should be poured promptly.
  • Most other impression materials compress the tissue too much, leading to increased adjustment time.

Adjustments

Special abrasives and techniques will allow you to make adjustments and fine tune the fit of any Valplast® partial just as you would with acrylic. Follow these simple instructions to ensure success when working with your next Valplast® case.
  • The abrasive that is most effective with a handpiece is a green silicone carbide abrasive point usually used for porcelain or precious metals. The green point will permit fine adjustments to be made with a minimal degree of roughness on the surface.
  • Simply use a rapid motion (with a light touch) and continuously vary the contact point.
  • The point can be used for effective reduction of the periphery edge, relief in tissue-contacting areas, and relief in supporting areas to relieve tightness or difficulty in insertion and removal.
Adjusting a Clasp

Material thickness and the design of a clasp play an important role in providing retention and stability to a Valplast® Flexible Partial Denture, it is important to exercise caution when adjusting a Valplast® clasp. In many cases it may not be necessary to adjust the thickness or gingival extension of a Valplast® clasp as this could change the flexibility of the material. If a clasp fits too tight in the patient’s mouth it is recommended to place the clasp in hot water for 60 seconds then bend the clasp outwards and allow it to cool down gradually to relax the elastic memory of the material. If a clasp is too loose you may use the same technique, bending the clasp inwards to tighten it.

Minor Relief

In some cases it may be necessary to provide minor relief to the denture in order to provide a better fit and increased comfort to the patient. This may be done by using the Valplast® #13 Green Stone on a slow speed handpiece to relieve the denture surfaces and borders. A constant motion of the bur over the material contact surface will yield a very smooth surface that usually does not require repolishing.

Adding Teeth & Rebasing Valplast®

To add teeth to Valplast®, take an alginate impression with the case in place in the mouth. Remove the case from the mouth while still in the impression, making sure that all pastes and adhesives have been removed and the partial is fully seated in the impression. Pour the model promptly and forward it to your Certified Valplast® Laboratory with your prescription. To rebase a Valplast® partial, begin by taking a rubber base impression underneath the case. The patients mouth should be closed to ensure full and correct occlusion as the rubber base material sets. When the rubber base has set, take an overall alginate impression and remove the case from the mouth making sure that the case is still properly positioned in the impression. Pour the model promptly and forward to the laboratory without separating the denture from the model.

Polishing:
  • Repolishing is generally not necessary when the green point is used properly.
  • If repolishing is necessary, it can be done with coarse pumice and brown tripoli using a soft rag wheel.
  • A high luster can be restored to the surface using Val-Shine polishing compound following the tripoli application.

Patient Delivery

Valplast uses a unique tissue bearing technique for retention for which no tooth or tissue preparation is needed. Your Certified Valplast Laboratory requires only a model poured promptly from an alginate impression and counter-model. A wax try-in is suggested prior to completion of the case. Special abrasives and techniques will allow you to make adjustments and fine tune the fit of any Valplast® partial just as you would with acrylic. Follow these simple instructions to ensure success when working with your next Valplast® case.

First Insertion of a Valplast® Denture

Valplast® resin is engineered to provide exactly the right degree of strength and flexibility inside a patients mouth. In order to facilitate a smooth first insertion of the denture it is best to simulate the conditions of the oral environment by bringing the Valplast® denture up to body temperature. This may be done by immersing the denture in hot tap water for a period of 30-60 seconds before inserting it in the patients mouth. This will give the material the same flexural modulus that it would have at body temperature and will enable the patient to adapt to their new prosthesis faster and easier. This procedure will also provide you with important information regarding the fit and comfort of the denture in the event that it may need minor adjustments.

Insertion Technique
  • 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.
  • Leave the partial in the water for about one minute.
  • Remove the partial from the water and allow it to cool just to the point where it can be tolerated by the patient.
  • Gently insert the partial in the 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 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 in the laboratory, we need 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.


Patient Care

Congratulations on choosing Valplast® for your new dental restoration. Valplast® has been in wide clinical use since 1953 and is enjoyed by millions of dental patients around the world. You‘ll be glad to know that most patients become immediately accustomed to their comfortable and light-weight Valplast® restoration. However, you may experience a brief adjustment period, especially if you have never worn a dental appliance before. Should you experience any persistent irritation, please consult your dentists so that he or she can make necessary adjustments to your appliance.

Valplast® restorations, like your own teeth, require care and good oral hygiene. To keep your Valplast® restoration looking and feeling like new, please follow these simple directions:
  1. Clean your Valplast® appliance regularly. Val-Clean Concentrated Denture Cleaner will safely, quickly, and effectively maintain the cleanliness of Valplast® partials as well as other removable dental appliances. Other brands are not recommended as they will not effectively clean your Valplast® appliance. Val-Clean® is easy to order by calling toll-free (888)325-3260 or by placing your order online at www.valclean.com.
  2. Soak your Valplast® appliance in Val-Clean® for 10 - 15 minutes a day or whenever it is not being worn. If staining develops, the appliance may occasionally need to be soaked overnight.
  3. Loose particles can be removed with the use of a Valplast® Sonic Denture Cleaner, or by placing the appliance under running water. Brushing a Valplast® appliance is only recommended with the special Valplast® cleaning brush as other brushes may remove the polish and roughen the surface of the appliance over time.
  4. Whenever possible, rinse your Valplast® appliance after eating to remove food particles.
  5. Keep the partial in water whenever it is not being worn to keep the surface hydrated.
  6. Remember to brush your natural teeth and gums regularly as directed by your dentist.
  7. Please keep the appliance out of reach from pets. Dogs and other pets find dental appliances to be attractive chew toys.
  8. Valplast® appliances are very durable and are designed to give long term performance under normal usage. Please note that the Valplast® base material will resist fracture or breakage better than the synthetic teeth that are embedded in it. Small accidents such as dropping the appliance in the sink or on the floor will not damage the Valplast®, but may cause the teeth to fracture. Please handle the appliance with care.
  9. Contact your dentist if you experience any discomfort from your dental restoration or if you ever have any abnormality with your natural teeth or gums.
