  2. Dental porcelain - Wikipedia

    en.wikipedia.org/wiki/Dental_porcelain

    Dental porcelain (also known as dental ceramic) is a dental material used by dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges, and veneers. Evidence suggests they are an effective material as they are biocompatible , aesthetic , insoluble and have a hardness of 7 on the Mohs scale .

  3. Pediatric crowns - Wikipedia

    en.wikipedia.org/wiki/Pediatric_crowns

    Pediatric zirconia ceramic crowns are made of zirconium oxide stabilized with yttrium oxide. These are highly durable and are used for restoring both primary anterior and posterior teeth . [ 7 ] They have been in use for children since 2010.

  5. Crown (dental restoration) - Wikipedia

    en.wikipedia.org/wiki/Crown_(dental_restoration)

    The "graded" zirconia crown has a darker cervical area consisting of tetragonal zirconia, a main tooth color in the buccal area, and a translucent incisal edge consisting of cubic zirconia. The only thing a dental technician has to do is to use the proper height of the zirconia block so that the crown fits in all the different color zones.

  6. Zirconium - Wikipedia

    en.wikipedia.org/wiki/Zirconium

    Zirconium is a by-product formed after mining and processing of the titanium minerals ilmenite and rutile, as well as tin mining. [25] From 2003 to 2007, while prices for the mineral zircon steadily increased from $360 to $840 per tonne, the price for unwrought zirconium metal decreased from $39,900 to $22,700 per ton.

  7. Cubic zirconia - Wikipedia

    en.wikipedia.org/wiki/Cubic_zirconia

    Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO 4). It is sometimes erroneously called cubic zirconium.

  8. Yttria-stabilized zirconia - Wikipedia

    en.wikipedia.org/wiki/Yttria-stabilized_zirconia

    Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" ( Zr O 2 ) and "yttria" ( Y 2 O 3 ), hence the name.

  9. Zirconium dioxide - Wikipedia

    en.wikipedia.org/wiki/Zirconium_dioxide

    Zirconium dioxide (ZrO 2), sometimes known as zirconia (not to be confused with zirconium silicate or zircon), is a white crystalline oxide of zirconium.Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite.
