Premium Cobalt-chrome partial denture alloy

Partial dentures par excellence

  • Enhanced version of the top-quality alloy WIRONIUM®
  • Can be used universally in the field of combination work and clasp partial dentures
  • Problem-free processing using the BEGO partial denture system
  • Very low thermal conductivity means high wearing comfort for the patient
  • Increased elongation limit and high modulus of elasticity for high resistance to possible deformations caused by masticatory forces
  • The high elongation limit minimises the danger of clasp fractures
  • Controlled carbon content ensures excellent laser welding properties
  • Biocompatible and corrosion-resistant
