Valplast - Partial Denture
Valplast - Partial Denture
Our Flexibility means Adjustability
When you are initially fitting a Valplast partial, you have the freedom to make the same adjustments in your office that you would normally make with rigid partials. The techniques and tools vary slightly, however you still have control of the fit.
There are Valplast-specific abrasives and techniques that allow you to maintain the finish and fine tune the fit for your patient's optimal comfort. The appropriate grinding tools, polishing compounds and Valplast® Knife are available directly from Valplast International or your supplier.
Clinical Preparation
Valplast uses the Retento-Grip® tissue-bearing technique for retention. No tooth or tissue preparation is needed. The authorized processing laboratory requires only a model poured promptly and carefully from a mucostatic impression and counter-model. A wax try-in is suggested prior to completion.
Inserting Valplast Partials
Simply by placing the case in very hot tap water for approximately one minute, you can achieve a very smooth insertion and an excellent adaptation to the natural tissues of the mouth. If a clasp isn't fitting perfectly, you may adjust it slightly by immersing that area of the partial in hot water and bending the clasp outward or inward as needed.
If any reduction is needed due to persistent irritation, the resin must be handled differently than acrylic. We recommend a #13 Green Mounted Stone, typically used for porcelain, to quickly reduce the surface yet leave it very smooth. If any threads remain, you may remove them with a sharp blade and smooth any roughness with a brown rubber wheel. You may then repolish the surface with Acrylux®150, Brown Tripoli and the Mirror-ShineTM polishing compound.
Adding teeth to Valplast
As the structure and conditions of your patient's mouth change over time, additions and relines can also be made with help from your lab.
To add teeth, take an alginate impression with the case in place in the mouth. Then remove the case from the mouth while still in the impression, making certain that all pastes, adhesives, or lubricants have been removed and the partial is fully seated in the impression. Pour the model promptly and forward it to the laboratory with your instructions.
Rebasing Valplast
To rebase a Valplast partial, begin by taking the rubber base impression under the case. To assure full and correct occlusion as the rubber base material sets inside the partial, your patient's mouth should be closed. When the rubber base impression has set, take an overall alginate impression. As you remove the case from the mouth inside the impression, make certain the case is positioned correctly in the impression. Pour the model promptly and send it to the laboratory without separating the denture from the model.
