Wironit

Wironit®, The classic partial denture alloy for clasp partial dentures

  • Successful worldwide since 1953 – ideally suited for conventional clasp partial dentures.
  • The reduced Vickers hardness allows easier finishing and polishing.
  • The clasps can be activated very easily by the dentist.
  • Biocompatible and corrosion-resistant.
  • Type 5: Indicated for prosthetic restorations where parts thereof require a combination of high rigidity and strength, e.g. thin removable partial dentures, sections with thin cross-sections, clasps.
