Today, functionality is not the only concern for patients.
Aesthetics, biocompatibility, and cost play an important role
when deciding which material to use for a fixed restoration.
Zirconia is an excellent material that dentists use to meet
patients' expectations and achieve outstanding results.
In this article, we will discuss what zirconia is and its uses
in fixed dental restorations.
Where Does Zirconia Come From?
Zirconium dioxide, commonly known as zirconia, is a ceramic
material obtained through a chemical reaction where the
mineral "zircon" undergoes an oxidation process.
During oxidation, most metallic atoms separate from the
zircon, leaving a chemically non-reactive material, turning it
into a metal-free ceramic.
Zirconia in Dentistry
Zirconia is a resistant material with excellent aesthetic
qualities. Therefore, it is an excellent option for fixed
prostheses.
Zirconia Dental Crowns
Due to its strength and resistance, it works perfectly as a
ceramic crown without the need for a metal framework.
Because of their position in the jaw, molars withstand the
strongest biting forces. However, zirconia is capable of
resisting them, making it the ideal material for aesthetic
molar restorations.
Its resistance makes it a durable material that can last
several years before needing replacement or repair.
Additionally, zirconia possesses exceptional aesthetic
qualities with smooth and soft surfaces, similar to natural
teeth. Therefore, it is an excellent alternative for anterior
teeth cases.
However, its color can be opaque, which sometimes makes it
difficult to match with the other teeth in the mouth. This can
be solved by adding a porcelain veneer layer to the zirconia,
improving its color properties.
Zirconia crowns can be manufactured with CAD/CAM technology.
Additionally, the dentist can make the crown on the same day
you visit the office. This way, you can avoid the need to send
your dental impression to a laboratory while reducing the
amount of time you have to wait for your crown to be finished.
Zirconia Dental Implants
Zirconia has become a popular implant option among patients
seeking a more holistic approach to their treatment. Its
metal-free property reduces the risk of implant rejection
present in common titanium implants.
Its white, tooth-like color is especially useful in cases of
high complexity and aesthetic demand. Additionally, unlike
titanium implants, zirconia does not discolor or show through
thin gums.
Furthermore, zirconia is a non-conductive material, making it
less prone to bacterial colonization.
However, its design is still limited and can be used mainly in
simple cases with optimal conditions.
Today, zirconia has become one of the best materials for fixed
restorations. Its qualities make it a highly versatile
material, suitable for a wide variety of cases and scenarios.
Although it may not be as optimal as other options, such as
Emax, it is a perfect solution if you are looking for a
balance between quality, resistance, aesthetics, and cost.
