The Advantages Disadvantages of Zirconia Crowns

- Aug 07, 2018 -


Zirconia (zirconium dioxide) crowns are made of solid monolithic zirconia ceramic material. Although discovered in 1789 by the German chemist Martin Heinrich Klaproth, zirconia has been used as a biomaterial since the late 1960s. Its use as a dental restorative material became popular in the early 2000s with the advent of CAD-CAM technology. In the later part of the decade they became available as preformed crowns for primary teeth.



  • They are very aesthetic, with greater durability than composite strip crowns and pre-veneered crowns.

  • They are not as technique sensitive as composite strip crowns as the fabricated crown is cemented with self-adhesive resin cement rather than bonding.

  • They take a bit longer to place than stainless steel crowns and composite strip crowns, about the same as pre-veneered crowns, and less than open faced stainless steel crowns.


They are not recommended in patients that are heavy bruxers.

  • Greater tooth reduction is required.
