Does zirconia ceramic degrade in strength intraorally in 5-10 years?

  • Yes, all-ceramic materials degrade in strength over time - some more than others. Zirconia ceramic has an initial flexural strength of over 1200 MPa, so even if it degrades 5-10% or more, it is still significantly stronger than other ceramics.

What is the flexural strength of the zirconia/porcelain system?

  • Zirconia substructures have high flexural strength, 900-1200 MPa.But flexural strength is typically performed on a three-point bend specimen and is a function of relative thickness of the zirconia and overlaid ceramic, but it would not exceed the flexural

What is zirconia?

  • Zirconia is another name for zirconium dioxide (ZrO2), an oxide of the metal zirconium. Zirconia blocks and discs are used by dental laboratories to mill zirconia copings, frameworks or full contour zirconia crowns and bridges. These blocks are formed un

Are there differences among zirconia ceramics?

  • Differences among zirconia ceramics can occur with the level of purity of zirconia; grain size, trace elements and stabilizing compounds; and consistency of formulation. Differences can exist in shrinkage from batch to batch because of differences in the

Q: Why use zirconia – is this clinician driven or manufacturer driven?…

  • The use of zirconia copings is driven by improved esthetics, biocompatibility, and durability as compared to PFM. Zirconium Oxide (ZrO2) has a history of providing stability and being highly biocompatible. With such nature, ZrO2 has been chose by the dent
