Abstract:
Zirconia is the oxidized form of zirconium and can exist in several phases, depending on the temperature. In dental ceramics, zirconia can inhibit crack growth and prevent catastrophic failure. The following case report demonstrates the use of zirconia as a framework material. Overall, zirconia has proven to be a strong and reliable framework material. In combination with CAD/CAM, this material allows for the fabrication of esthetic all-ceramic restorations in all areas of the mouth.
