Zirconia, a polycrystalline ceramic material, has proven to be extremely
successful for prosthetic dental restorations. Bioart Dental’s superior
technical ability to work with Zirconia applies to even the most
demanding aesthetic cases.
While traditional Porcelain Fused to Metal (PFM) Crowns were a
great technical improvement when first introduced, one of the
disadvantages has been the development of unsightly black
lines at the margin edge as gums recede over time. Zirconia’s
tooth-coloured core eliminates the risk of black lines.
Zirconia also has outstanding stability and biocompatibility, and
is significantly stronger than conventional ceramic materials.
Zirconia is suitable for a wide range of crown and bridge
applications for both anterior and posterior prosthetic
requirements.
Sourcing frameworks from a variety of suppliers allows Bioart
Dental to advise its dentists about the very best product for a
particular case.
With the use of innovative CAD/CAM technology, Bioart Dental
supplements the framework with a specially designed veneer
ceramic.
Zirconia’s superior durability and aesthetics make it an excellent
choice as an all ceramic system, this is evidenced by the
increasing demand for Zirconia Crowns over the traditional
PFM crown.
Bio Z Translucent Zirconia
The use of monolithic translucent Zirconia has become
increasingly popular for use in the posterior region.
Considerable advancements have been made in this material
to make it a more aesthetic option for use as a full contour
crown. Due to Zirconia’s incredibly high flexural strength, it is an
excellent choice for all posterior crowns or bridges.
Whilst some dentists have expressed their concerns about the
wear of the enamel when opposing full contour Zirconia crowns
and bridges, recent studies have found that glazed Zirconia is
compatible with enamel. In fact, it is virtually identical to glazed
IPS e.max.
Zirconia's Advantages
Accuracy of Fit
The excellent fit demanded for clinical success is achieved
with CAD/CAM milling accuracy combined with precise
computerized calculation of the sintering shrinkage so that the
cement gap can be adjusted to individual requirements.
Unparalleled Strength
Zirconia has an ability to withstand many times the large
occlusal forces in both anterior and posterior area, thereby
making it one of the few polycrystalline ceramics suitable for
use in dental framework materials.
Improved Aesthetics
Zirconia’s material properties allow a low wall thickness in order
to deliver an ideal tooth-like translucency.
The strength of the relatively thin framework allows optimal
space for the layering technique of ceramic - even in difficult
situations (if required.)
The Zirconia framework is available in a number of different
shades, opacity and translucency. This produces an optimum
aesthetic result when combined with a specially designed
veneer ceramic.
Biocompatibility
Zirconia has a very high level of biocompatibility, this is
supported by the fact it has already been in use for more than a
decade as a material for surgical implants such as hip joints.
Clinical studies show that Zirconia oxide and the veneer
ceramic don’t produce any measurable solubility of allergic
potential nor any irritation of the tissue.
Unlike metal supported units, Zirconia has low thermal
conductivity, eliminating sensitivity to temperature variation,
while exhibiting plaque accumulation similar to that of a
natural tooth.
Established Dental Technique
Bioart Dental understands dentists want the advantages of
new technologies and materials without wholesale change to
established preparation or impression methods.
Using Zirconia allows conventional cementation yet produces
unconventional results. For exceptional aesthetics, Zirconia has
achieved excellent results for Bioart Dental clients.
It delivers an extremely natural appearance where the crown
emerges from the gums and if the root is later exposed by
receding gums, the Zirconia continues to transmit light to the
root, enhancing its natural effect.
Bioart Dental can offer Zirconia at different translucency levels
and colours to best suit the clinical and patient needs.
Australian Made
All restorations sent to Bioart Dental are
designed and made in Australia using
TGA approved products. Bioart Dental
technicians are available to discuss cases
that could benefit from a Zirconia restoration
for anterior or posterior applications.
