Short history of the system: People’s awareness about their general appearance was raised after 1940s. Demand for cosmetic restorations increased. Supplying gold and ebonite materials became more difficult and accordingly, their prices became higher. Arpad and Tibor Nagy began to conduct studies on these flexible materials in 1940. Valplast Company exported its products to Europe in 1953 for the first time and sale of products in USA was approved immediately after it. Now, the products are in use in 75 countries and approximately 2.5 millions of Valplast partials are in use.
Target in design of a partial:
•Target in design of substructure: To keep and support the partial
•The aim in conventional HBP designs, to balance needs for retention and support while minimizing damages on natural dentition and bones.
Limitations of rigid partials:
Metallic structures cause crochets to be seen. They require routine maintenance and modifications for maintaining stability.
 Flexible Partial Theory: :
there is no occlusal rest, less tooth mobility, requiring less teeth to be pulled away, there is no need for tooth preparation, there is no metallic view, crochets are supported by tissue surface instead of natural dentition, much better looking compared with systems including metallic crochets,
Tissue based application, each part in the mouth media is flexible, Thanks to flexible nature of the Valplast system, forces are equally distributed on the crest, – absent of any rigid material eliminates unnatural forces.
Functional solution: Elasticity acts as a stress-breaker and loosens forces acting on individual bases. It ensures a well-balanced force distribution on surfaces with no tooth, bases acts as a suspension as independent from each other.
Cases and special Valplast Applications: A theory is valid as long as it can be put into practice. Here are examples showing application in practice.

Measuring: Mucostatic measurement should be taken diligently to ensure close-fit and comfort. Alginate is recommended. Canister should be twisted to ensure that heavy components are distributed equally and for controlling shrinkage. The model should be cast immediately after measurement before sending it to a laboratory. PVS or similar materials cause a close-fit. |
 Premarket Notification (510k) : Valplast resin is in FDA Class 2 medical tool; however, it does not include 510k Amendment. Medical tools existing in the market commercially before 28 May 1976 were made exempt from FD&C’s 510k medical device assessment. Because the Valplast system has been available in the market since 1953, it is assumed as “pre-amendment” and therefore, it does not have the amended 510k.
Insurance Code Numbers:
Code no relating to flexible partials in the list of ADA’s CDT-2005:
•D5225 – Maxillary partial prosthesis (flexible)
•D5226 – Mandibular partial prosthesis (flexible)
