TECHNICAL NOTES
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 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.

Valplast Cleaner- Mirror Shine can be purchased through the manufacturer 1-800-843-2861
VALPLAST RE-BASE IMPRESSION PROCEDURES
When re-basing a Valplast partial, our lab is removing all the Valplast material, re-waxing and then re-injecting using the same procedures used in making a new partial.

The steps for taking impressions for a Valplast re-base are as follows:
1. Take a re-base/tissue impression inside of the Valplast partial.

Before you insert the partial into the mouth for reline, inject a small amount of impression material around the buccal of the teeth that are clasped. This will ensure that the undercut areas are captured.

Please note that when the partial is a Valplast/Vitallium combination, it is very important that the impression material doesn't flow over the major connector of the framework.

Recommend the use of a poly-vinyl siloxane material. Use adhesive provided with the material to keep the impression material from pulling away from the Valplast partial when removing from the patient's mouth.

2. Take a pick-up impression with tissue impression of the Valplast partial in place. It is very important to use the same impression material for the pick-up impression as the tissue impression for compatibility. Make sure that the pt is in full occlusion when taking the tissue impression to assure that the bite is not opened.

3. Our laboratory requires that an opposing model always be provided.

4. Our laboratory requires that a bite registration always be provided.

tcs vs. VALPLAST
The materials are very similar and have the same limitations. However, the benefit of using tcs is that processing tcs is more efficient than Valplast. With Valplast, the material has to be at a very high temperature and has to be injected at a rapid rate. Because the Valplast material requires a high temperature, and requires a lot of pressure to inject, the material can get over heated and cause slight discoloration. Valplast is injected with a lot of pressure from the oven, and because of the amount of pressure that is used, we sometimes will get a processing error, because with the force of the injection, the teeth will slightly move.

With tcs, the processing equipment is much more "processing friendly". We can process with less heat and less pressure which will help eliminate processing errors.
INDICATIONS / CONTRAINDICATIONS
Valplast and tcs are recommended for use as removable partial dentures in place of traditional acrylic saddles on cast metal partials, flippers, or stayplates. Valplast and tcs are tissue borne appliances when not used with cast metal partials. Rest seats in Valplast are not recommended. Valplast and tcs eliminate the need for invasive procedures.
Valplast and tcs 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 and tcs cannot be relined chairside; appliance needs to be returned to the lab for rebase.
PREPARATION
Start with an accurate bite registration and void-free impression using a custom tray.
CEMENTATION
No cementation necessary.
WORKING TIME
7 Days In-Lab
Rush Cases : All rush cases must be prescheduled by calling 800-944-7874 before the case is shipped. Time of pickup and delivery may affect turnaround time.
