Bego Wironium Frameworks
Consider these benefits for your next R.P.D. case.
- Lower Vickers hardness: Wironium is less abrasive to opposing dentition and restorations.
- Higher yield strength: Wironium's higher yield strength gives an indication of when permanent deformation will occur.
- Higher tensile strength: more resistant to fracture under tension.
- Higher elongation value: Wironium has more than double the elongation of Vitallium with less brittleness and less tendency to fracture during service.
- Increased "toughness": Because of its higher elongation value and tensile strength, Wironium is more resistant to work hardening (fracture during adjustments).
- Higher modulus of elasticity: Wironium is more rigid and thus requires less bulk for the required amount of rigidity.
- The most precise fits of any partial denture system that we have ever used!
