When to Choose Metal Framework Over Other Types of Partial Dentures

Partial dentures with metal frameworks are often chosen over other types of partials when precise fit and stability are a concern. Metal frameworks are also suited for cases when retention by semi-precision- or precision-attachments is desired.

Qualities of Wironium

  • Wironium is a proprietary nickel- and beryllium-free cobalt chromium alloy developed by BEGO USA.
  • The material is biocompatible and corrosion-resistant.
  • Wironium is thin but incredibly strong and durable.

Special Features of Wironium

  • Wironium is highly resistant to deformation.
  • Wironium has similar properties to a Type IV gold and may be cast to be incredibly thin.
  • The alloy is semi-flexible and resists fracture of the metal clasps.
  • Vacuum casting ensures a precise fit while eliminating voids in the metal that can cause defects and weaknesses.
  • The material is lightweight, especially when compared to other cobalt-chrome formulations, which provides enhanced comfort for your patients.

The Best Way to Take Impressions for Wironium

  • A thin, stable bite registration is desirable for accurate articulation.
  • Distortion-free impressions should be taken using traditional alginate.
  • The Accudent impression system by Ivoclar is another excellent option for taking impressions.
  • Rubber base or polyvinyl siloxane impressions are generally not necessary.

Delivery and Seating

  • The precision of vacuum casting allows Wironium partials to seat right the first time.
  • Malleable clasps conform to the tooth contour and are designed to engage with the natural undercut.
  • Correct fit upon insertion reduces excessive adjustments, metal fatigue, and saves valuable chair time.


  • Generally, only minimal adjustments are required when using Wironium.
  • It is possible to tighten or loosen the clasps at chairside without worrying about breakage.


  • Strong, durable repairs and additions to existing cast metal partials may be made via laser welding using proprietary Wiroweld welding wire and Wironium companion products.
  • Repairs to other cast metal frameworks, such as Vitallium, may also be made using the Wiroweld system.

Hybrid Partials using Wironium

  • It is possible to combine Wironium with Thermoflex or Valplast flexible partial denture materials to create a hybrid partial that possesses all of the benefits of the flexible material with the added strength and stability of Wironium.
  • This feature is particularly important in the case of free-end or long-span partials where partial dentures from flexible materials don’t always function ideally.
  • Another benefit of hybrid partials allows for tooth-colored or tissue-colored clasps to be used in combination with a Wironium framework and bracing elements to improve the appearance of the partial denture.


Wironium is virtually unbreakable. In the event of breakage under intended use, a two-year warranty is provided.
