FAQ

Q: Are there differences among zirconia ceramics?

 

A: 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 coefficient of thermal expansion (CTE).

 

Q: Zirconia substructures have high flexural strength, 900-1200 MPa, but what is the flexural strength of the zirconia/porcelain system?

 

A: 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 strength of the zirconia.

 

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

 

A: 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.

 

Q: Does shading or coloring zirconia ceramic reduce the strength as compared to the uncolored zircona?

 

A: Weakening of colored zirconia ceramic copings has not been observed.
