FAQ
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.
Q : Is the fit of crowns and bridges based on zirconia copings as
good as that of PFM crowns and bridges?
A : Yes, the marginal fit of crowns and bridges fabricated from
zirconia copings can be as good or better than PFM crowns and
bridges.
