Patients expect a miracle from prosthesis. Orthopedists and dental technicians have to meet their anticipations. To achieve this, modern materials are required. The use of alloys of non-precious metals will probably be gradually decreased in future in view of its possible side effects. Therefore, a wide range of alloys has been developed using precious metals. Zirkonium dioxide was discovered in 1789 by the German scientist M.H. Klaproth. However, its amazing properties were "re-invented" in just recent years. High mechanical durability, biocompatibility, phase conversion and color of a natural tooth are the basic advantages of zirkonium dioxide for producing aesthetic and durable restorations. That's why, zirkonium was introduced into medicine and dentistry as an ideal replacement for the metal. Zirkonium dioxide is partially stabilized by Yttrium and is responsible for its positive mechanical properties. Color and biotechnique properties determin the production of high quality and aesthetic tooth and implant retained restoration, which is biocompatible.
