These negatives can be overcome by marrying Valplast or Thermoflex denture material with a Wironium metal framework. The best features of each partial material will work synergistically to create a partial denture with the desired properties of rigidity and asthetics. This allows for “invisible” flexible clasps and gum-hugging tissue-borne material to be used when supported by an underlying Wironium metal framework and/or metal rests and clasps.
Wironium is a proprietary cobalt-chrome alloy developed by Bego USA, Inc. Wironium is both bio-compatible and corrosion-resistant. Small changes in the standard cobalt-chrome formulation have resulted in an alloy that has a high resistance to deformation while the cast alloy itself is semi-flexible and resists fracture of the retentive metal clasps. These unique properties allow Wironium metal frameworks to be incredibly thin yet strong and durable.
Because Wironium is nickel-free, it is safe to use for those dental patients who have developed a sensitivity to nickel. Wironium is appropriate for use with traditional acrylic saddles in patients that have not become sensitized to acrylic monomer.
To custom create a completely bio-compatible cast metal partial denture, combine Wironium with either Valplast or Thermoflex. The result is a hybrid flexible partial denture that cannot be over-seated and doesn’t over-flex at the back of the arch during chewing. Literally, the result is a customized, nickel-free, monomer-free partial denture that has great function and the best possible aesthetics imaginable. What more could you ask for?
