Valplast Flexible Partial Dentures
Valplast Flexible Partial Dentures
ESTHETIC - the translucent material blends naturally with the tissue tone and replaces clasps
COMFORTABLE - thin, lightweight and resilient with precision fit and retention
BIO-COMPATIBLE - non-allergenic, monomer and formaldehyde free
FUNCTIONAL - flexible to create a stress-breaker effect, with no minor or major connectors to collect food or affect speech
In dentistry there are many options for the replacement of missing teeth - dental implants, fixed bridges, removable partial dentures, and full dentures. Many patients choose removable partial dentures due to factors ranging from cost to physiology. Removable partial dentures became very popular many decades ago when chrome cobalt alloys and acrylic polymers first became available to the dental industry.
Dentists are prescribing Valplast Flexible Partials because it makes a better, stronger appliance faster. The strong, flexible nature of Valplast is perfectly suited to the variety of natural conditions in the mouth, simplifying design and enabling the flexible nylon resin to act as a built in stressbreaker in order to provide superior function and stress distribution in a removable partial denture.
|Valplast is one of the most cosmetic, comfortable and affordable methods of tooth replacement available today.
Since 1953 millions of people have discovered the exceptional benefits that Valplast can bring to their appearance and confidence, providing them with something that they can truly smile about.
Innovation is often inspired by the need to make improvements in peoples lives. Valplast® was first developed in the late 1940s when the acknowledged functional and cosmetic limitations of framework supported RPDs created a need to fundamentally change how removable partial dentures are designed and fabricated. Two young brothers, Arpad and Tibor Nagy, had the vision to experiment with the new polymers of the day (nylon) to create a type of partial denture that was able to address the fundamental requirements of retention, support and stability while at the same time provide beautiful aesthetics that are far superior to their metal counterparts. Their research gave birth to what is known today as Valplast®.
|A Metal-Free Flexible Option
The future of dentistry lies in metal-free restorations. Valplast® is the optimal choice anytime partials are indicated or the patient prefers not to use a fixed restoration. Patients who have worn both conventional RPDs and Valplast® partials report that Valplast® feels more natural and is more comfortable to wear. Valplast® also provides a higher standard of function by using the flexibility of the material to balance masticatory forces over the entire supporting ridge instead of individual support points. As a result, the balanced distribution of forces can often lead to longer lasting apppliances that may not require frequent relines or tooth additions.

Valplast® is available in five natural tissue shades as well as an additional unpigmented option for special applications. The unique physical properties of Valplast® also make it more adaptable in challenging cases and situations involving pediatric patients, cancerous mouths and cleft palates. Because of its excellent biocompatibility, Valplast® is also an ideal replacement for acrylic when patients are allergic to denture acrylics. Additional applications for Valplast® include cosmetic gum veneers, bruxism appliances, implant retained overdentures and full dentures for patients with protuberant bony structures or large undercuts.
|Flexibility Means Adjustability
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.
Adjusting a Clasp
Because 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 patients 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.
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.
