Zirconium dioxide is a material which, over the recent years, has been attracting support among dental technicians and dentists, thanks to its chemical composition and mechanical properties, it can replace nonanaesthetic foundations or metal crowns. Additionally zirconium dioxide is a material which is easy to work in. Zirconium dioxide is a polymorphic material demonstrating three phases: monocyclic, cubic and tetragonal. Additionally during the crack propagation the material shows the reinforcing transformation; the replacement of the phase and increasing the volume of the molecules, which inhibits the microcracks in the material. Thanks to such potential, zirconium dioxide has acquired a very high recognition in stomatology and orthodontics. Interestingly, the factor which has a considerable impact on the fatigue life and strength of zirconium dioxide is an adequate treatment and tool operation temperature; the slightest undesired effect can trigger the accumulation of stresses and thus decrease the material strength. A lower mechanical strength can be also due to other conditions, e.g. varied nutrition habits in the patient and the frequency of oral cavity hygiene practises.
