Dental Caps For Teeth Germany Wieland Zeno Corrosion Resistant
Zirconia crowns are made of zirconia or zirconium oxide, and are
very tough and durable in nature. Since such crowns have several
advantages over traditional metal and porcelain dental implants,
many people these days prefer to opt for them. So, here’s a brief
overview of the advantages and disadvantages of zirconia crowns:
|Material brand||country of origin||Ingredient||Bending resistance||Indication||Security|
Yttria and Hanium Oxide <10%
|Around 1000MPa||crown,Inlay,More than 8 can be made up||<0.2Bq|
- Natural look: Zirconia crowns can be translucent enough to blend
with other teeth and give a natural look. What’s more, if bonded to
the teeth rather than being cemented with conventional dental
cement, these crowns won’t display a black line at the gum line.
- Strength: Where porcelain crowns are prone to chipping, zirconia
crowns are almost indestructible. In fact, these crowns can be up
to five times stronger as compared to their porcelain/metal
- Durability: Unlike crowns of other materials that may typically
last for around 10 years or so, those made of zirconia are likely
to last a lifetime.
- Less sacrifice of healthy tooth: Since zirconia crowns can offer
superior strength in less volume than crowns made of other
materials, they can be made to fit even when not much space is
available for porcelain build up.
- Biocompatible: Zirconia is completely compatible to human body.
Since it is inert, and the body does not reject zirconia, you need
not worry about facing allergies or unfavorable reactions.
- Corrosion resistant: Zirconia crowns are resistant to corrosion,
which adds to their longevity factor.
- Less labor-intensive: Since more of the present tooth is retained,
nominal preparation is required for fitting these crowns as
compared to metal or porcelain crowns.
- Cost-effective: Zirconia crowns are considerably cheaper than
porcelain crowns, and cost almost the same as gold-based
metal-porcelain crowns. However, the long list of benefits that
they bring to the table make them cost-effective than crowns made
of other materials.
- Abrasive effect: The toughness of zirconia crowns can have an
abrasive quality, which causes friction against the root of the
affected tooth as well as with other teeth.
- Decay under the crown: Though these crowns are meant to last a
lifetime, the decay underneath the crown my cause them to loosen
As with everything in life, advantages often come with a price.
This holds true for zirconia crowns too. Still, when you weigh the
long list of advantages against a minor setback or two, zirconia
crowns surely emerge as the prudent choice.
