Zirconium is a chemical element and its symbol is Zr. It comes from the Arabic word zargon, meaning "its color resembles gold".
It is a metal element in the 4-B group of the element table, with the chemical symbol "Zr". Its melting point is 1855 degrees. It is a grayish white metal. It is resistant to heat and corrosion. Its fracture resistance is 7-10 MPa. Its bending strength is 1570 MPa.
Zirconium has a high degree of mechanical strength. It is a material with very successful aesthetics and advanced biocompatibility. It is the hardest ceramic known in the dentistry industry. It is used in blocks of various sizes in the dentistry industry. Monolithic zirconium materials used with CAD/CAM technologies have been developed over time.
Monolithic zirconiums are partially stabilized with yttrium (0.01%). This increased the mechanical resistance of the metal. Zirconium has become more preferred with its successful aesthetic properties. In addition, in the presence of insufficient interdental distance, the rate of making monolithic zirconium restorations on implants also increases. Natural tooth color can be obtained by painting monolithic zirconium with special staining solutions.
The high resistance of monolithic zirconia to fracture provides the advantage of use in cases where interocclusal distance is insufficient. Their ability to show sufficient resistance and durability even at an occlusal thickness of 0.5 mm enables them to be used in posterior restorations.
