It's The Complete Solution For All Your Partial Denture Applications
      "Having used most of the commonly marketed removable partial denture alloys over the past 35 years, I would rate Wironium® number one. It comes closest to being the ideal removable partial dental alloy. It is light weight, tarnish resistant, tissue compatible, durable - and perhaps most importantly, it allows the retentive clasp arm to be adjusted without fear of fracture to a greater degree than any of the other commonly used chromium alloys on the market. In this respect its bending properties are similar to removable partial denture gold alloys. In effect, Wironium® encompasses those desirable retentive clasp arm properties contained in gold alloy and those desirable chromium properties for all other components."

      "The fit of a well-made Wironium® Removable Restoration is exceptional. Because the alloy is nitrogen enriched, Wironium® allows for precise castings with predictable, repeated adjustments of the clasp assemblies. This allows the dental practitioner to feel comfortable in that the restoration will be a success. Recently, I had the opportunity to try-in a Wironium® frame for evaluation. Upon seating the frame, the patient asked if it was in yet! The fit was so excellent that the patient was unaware that the frame was in her mouth."

      "Since graduating from my prosthodontic training program at UCLA in 1994, I have used Wironium® frameworks exclusively for my conventional and precision removable partial dentures as well as for some implant/tissue supporting partials. I have found Wironium® alloy to be exceptionally strong, yet flexible, easily adjusted during try-ins, and lightweight. The Wironium® process for duplicating casts, waxing, casting and finishing the frameworks is exceptionally accurate."

      "The alloy is casting very slender clasp arms with no discernible porosity under magnification or x-ray. I and my patients have been pleased with the high luster finish of the Wironium® alloy. I was a technician for 20 years and these castings are the nicest I have seen."

      "My experience using Wironium® metal for RPD prosthetics has been uniformly positive. The metal has the fit and feel of the premium gold frames from past years."

      Europeans have made Wironium® the alloy of choice for decades. Wironium®, a unique alloy, contains no nickel or beryllium, is nitrogen enriched and is characterized by a particularly high ductile yield, greater elongation limit, and superior strength. Your patients will enjoy the benefits of increased retention, enhanced aesthetics and improved design when you select Wironium® precision removable appliances.
