Denture identification: a new band material and the Swedish ID-band revisited

The Swedish-developed ID-band has become the internationally accepted method for marking dentures and the Federation Dentaire International (FDI) has put its stamp of approval on the system, but recent research has indicated that the materials used for the metal bands are not resistant to the temperatures the material might be exposed to during fire. In this article, a new group of materials (nickel aluminides) is shown to have a unique combination of mechanical strength, ductility, microstructural high temperature stability and high temperature oxidation resistance in both oxidising and carbonising atmospheres, that make the material suitable for denture marking.
