Zircon Crowns

When patients require a cap of their tooth, zirconia crowns are one option a dentist may recommend to achieve that beautiful smile.

Zircon Crowns areextremely strong, and match the look of natural teeth well.  It has variable color shade and highly translucent.

Because of their exceptional durability and strength, Zircon Crowns generally last longer than porcelain, ceramic or emax crowns. While old type of crowns usually needs replacement after a few years, Zircon Crowns have shown a 99 percent survival rate after five years up to 25 years.

Dr Racha Ghazal ONLY uses Zircon, not porcelain, ceramic or emax, for Crowns, for his patients to get the most beautiful, natural-looking & durable Hollywood smile.

Dental crowns are caps that cover a tooth or a dental implant. Dentists often recommend crowns as a way to support broken, weak, or misshapen teeth.

Dental crowns can also be used to cover up a tooth that’s very worn down or severely discolored. They can also be used in conjunction with bridges to strengthen multiple teeth.

When it comes to the materials that crowns are made of, you have several possible options, including ceramic and metal. Another option that’s now available for some people is a zirconia crown.

Zirconia crowns are made from zirconium dioxide, a very durable type of metal that’s related to titanium, although it’s categorized as a type of ceramic crown.

What is dental zirconia?

The dental zirconia is zirconium dioxide (ZrO2), which is a powdered form of zirconium. Since the 1990s, zirconia is used for endodontic posts and implants. (Endodontic post helps you retain your restorations and fillings as well as crowns.)

Types of zirconia

There are two types of zirconia: solid and high translucent. Both of them can be made using the CAD CAM technology. CAD stands for Computer Aided Designing and CAM stands for Computer Aided Manufacturing. These technologies give you a precise fit and unmatchable look.

Solid zirconia

As the name suggests solid zirconia is tougher compared to the high translucent zirconia. It can withstand chewing forces as well as bruxism forces better.

Solid zirconia also suits root canal treated teeth, by offering stronger support to weak teeth.

As it’s opaque, it’s more suited for posterior/ back teeth.

High translucent zirconia

This is a type of zirconia which gives you superior looks that exactly resemble your natural teeth. It is more suited for anterior/ front teeth.

Though it is superior in looks, its strength is higher than PFM/ Porcelain Fused to Metal bridges.

If you need extensive orthodontic treatment to correct the alignment of your teeth, your dentist may not prefer high translucent zirconia.

How is a zirconia crown prepared?

It is prepared from a single block of zirconia and is known as a monolithic zirconia. Therefore, they are resistant to fracture as well as wear and tear. You can have a zirconia crown via a single sitting as well as multiple sitting appointments.

Earlier zirconia crowns used to have a porcelain layer which used to chip off. Now with the use of monolithic zirconia, your crown does not chip off.
