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.
