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.
Valplast® resin is engineered to provide exactly the right degree of strength and flexibility inside a patient’s 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 patient’s 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.
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 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.
