ZIRCONIA CROWN-NEW KING IN THE DENTAL WORLD
I. What is Zirconia?
Zirconia is a white solid ceramic glaze, non-metallic material consisting of zirconium dioxide, with the highest mechanical strength and fracture resistance.
It is widely favored in the medical field because of its superior surface smoothness, biocompatibility, and longevity.
Most Zirconia in the market has a similar composition. Depending on the purpose of using Zirconia, the strength and the opacity will be slightly different. For example, full compressed Zirconia used for posterior crowns can get a maximum force of about 1.100 to 1.200 Mpa, while lightly compressed Zirconia used for anterior crowns has a maximum strength of 700 to 850 Mpa.
In terms of opacity, the layered Zirconia can accommodate maximum aesthetic for anterior transparency, while the lightly compressed Zirconia can get medium transparency. Therefore, you should compromise the strength if you want to get the highest clarity for your restorations. However, Zirconia is still more substantial than other dental materials.
Today, there are many different types of Zirconia with many brand names. To prevent confusion, you should choose the suitable kind of Zirconia based on your manufacturing purpose.
II. Zirconia Crown- New King in modern dentistry
During the last few decades, dental suppliers worldwide have introduced many kinds of dental materials. Many of them worked well initially but gradually faded about the strength, the color except Zirconia. Until now, Zirconia is considered the best material for dental restorations.
Before Zirconia is well known in the dental field, gold is the preferable material that can offer more benefits for anterior and posterior restorations. However, gold is no longer affordable to many patients because gold crowns did not offer a natural look
The revolution of the Zirconia crown started in the 2000s when gold prices started increasing, and the new CAD/ CAM technology was introduced in the dental lab. Zirconia has become a new king among other materials as many dentists chose Zirconia as an alternative to expensive gold.
As a company specified in manufacturing restorations, we believe that Zirconia is the best material for dental restorations recently, primarily based on 3 factors: biocompatibility, longevity, and aesthetics.
III. Why do dentists all over the world prefer Zirconia Crown?
Zirconia is well-known for its superior non-corrosive properties. Therefore, zirconia crowns are the most biocompatible, which means it’s less likely to provoke the body into producing a reaction or immunological response like inflammation, while other dental materials may contain some level of toxicity or allergic propensities. However, no material is suitable for all kinds of people. For safety, the dentist should check the patient’s allergies.
Zirconia crown can last for up to 15 years if correctly restored for a long time. It is ten times stronger than natural teeth. However, because its strength is not as good as metal, the zirconia crown should not be thinner than maybe 0.7mm for maximum longevity.
Zirconia is not the most aesthetic compared to lithium disilicate because of the opacity property of zirconium dioxide itself. However, in terms of aesthetics and strength, zirconia is the best choice for aesthetical factors among the most restorative dental material.
For maximum aesthetic, layered zirconia is the best choice. The framework made from zirconia and layered with porcelain will provide aesthetics for the anterior crown. The more aesthetic crowns, the more technician’s skill and ability to layer porcelain powders.
IV. Limitations of Zirconia Crown
One potential downside of a zirconia crown is its opaque appearance; However, this material resembles a natural tooth than gold and other metals. It is more transparent than real. This is especially true for monolithic zirconia crowns, which are made from zirconia, although it may be less of an issue for teeth in the back of your mouth. But if you need to replace a tooth in the front of your mouth, zirconia may have a noticeably different shade than your other teeth. Thus, it would help if your strength is compromised to get a slightly translucent appearance.
V. How to protect Zirconia Crown
Firstly, be sure to practice good oral hygiene with all of your teeth. Brush at least twice a day, floss, or clean between your teeth with interdental brushes or water flossers at least once a day. Besides, you can use other helpful products like antimicrobial mouth rinses and tongue scrapers. Be sure to see your dental professional for regular cleanings to keep your teeth white and bacteria-free and check the health of your crown.
