[The clinical application of Vitallium 2000 casting removable partial denture].
The casting removable partial denture (RPD) is one of most commonly prosthesis methods in present. Vitallium is one kind of dental alloy with cobalt, chromium and molybdenum etc. It has three ranks respectively: Vitallium, Vitallium 2000 and Vitallium 2000 plus. Although the traditional casting RPD are commonly used, but it has been limited in the physical capabilities of traditional dental alloy. It would not been done to flexible design on denture especially on denture base. The elasticity of casting clasp is not good, the volume is thick. Because of the Vickers hardness and elongation of Vitallium 2000 and Vitallium 2000 plus are better than traditional dental alloys, so the RPD with Vitallium 2000 has good bending control, deformation rebound and fracture resistance. The benefit of Vitallium 2000 or Vitallium 2000 plus is the RPD with splitting can be designed for some free end clinical cases, to solve some clinical problems.
