Dental crowns are plates that protect the dental implant. Dentists also prescribe crowns as a means of supporting missing, weak, or deformed teeth. Dental crowns may also be used to protect a tooth that is very broken down or badly discolored. They can also be used in combination with bridges to reinforce multiple teeth. When it comes to materials made of crowns, you have a range of choices, including ceramic and metal. A zirconia crown is another alternative that is now open to certain citizens.

Zirconia crowns are constructed of zirconium dioxide, a very strong form of metal connected with titanium, although known as a type of ceramic crown.

zirconia Dental crown benefits

Crowns made of zirconia are becoming more and more popular, and they do offer some benefits.

Strength

One of the greatest benefits of zirconia is its resilience and longevity. Remember how strong your back teeth are on the food you chew.

Your crowns need to be made of a solid substance, so zirconia would be a safe alternative for crowns in the back of the mouth. Also, since zirconia is so efficient, a dentist won’t have to do as much tooth preparation as he does.

Longevity of life

Zirconium-based crowns ran as well over the span of five years as metal-based crowns, according to a randomized trial released in the Journal of Dentistry in 2017. And crowns made of zirconia, called monolithic zirconia crowns, are exceptionally durable.

Bio-compatibility

Zirconia is the preference of many dentists for its biocompatibility, which means that it is less likely to cause allergies or immunological reactions such as inflammation.

This is confirmed in an in vitro analysis in 2016, which also found only a small amount of cytotoxicity.

Disadvantages of a crown of zirconia

There could be potential risks of having the zirconia crown like many other dental treatments.

It is difficult to match

An opaque presence that can make the crown look less than normal is a potentially downside. This particularly refers to monolithic zirconia crowns made only of zirconia, although it may not be a concern for your back teeth.

Potential to wear on other teeth

In certain cases, some dentists have refused to use zirconia coronations for fear of wear and tear on opposite teeth due to the rough nature of zirconia.

Although this may be a problem, a 2012 review in the Journal of Dentistry showed that feldspar porcelain was much more likely than zirconia ceramic to inflict wear on the enamel of opposing teeth.

The crown of Zirconia with porcelain

Zirconia can be a little hard to align with the rest of your teeth. That’s why certain dentists would place porcelain on the top of the zirconia as they make the crown.

A crown made of zirconia with a porcelain coating would give it a more natural look that can easily complement the color of your other teeth.

Other Dental Crown Types

Of course, the zirconia crowns are not your only choice. Other components widely used in crowns are:

  • Ceramics
  • Porcelain
  • Metals
  • Composite resin
  • Material combinations, such as porcelain-fused-to-metal (PFM)

You’ll want to speak to your dentist about the right material for your case. This would include how much of your natural tooth exists, the position and purpose of the tooth that requires the crown, the amount of gum that will appear as you grin or speak, and the color of your outer teeth.

The operation

There are two primary types of treatments to mount a dental crown. Your dentist will prepare the teeth and mount a temporary crown at one appointment and then cement the permanent crown in your mouth during the second visit.

Or, if your dentist has the necessary technologies and facilities to produce a zirconia crown in-office, you can have the same-day treatment.

Procedure on the next day

Many dentists will create zirconia crowns in their offices instead of taking the impression of the teeth to the lab to construct the crown. Then, with a single visit, they will seal the crown in your cheek.

CEREC, a method that utilizes computerized design/computer-assisted (CAD/CAM) technologies to speed up the process of economic restauration of esthetic ceramics. The dentist makes the crown from a block of zirconia using a dental milling machine.

This method removes the need to expand the treatment to two visits. Not every dental clinic, though, has this equipment in-house or sells zirconia crowns.

Double-visit process

The dentist is going to:

  • Take an X-ray of your mouth and brace your teeth for an operation that might require the application of a local anesthetic.
  • If possible, scrape part of the outer layer of your teeth.
  • Just make an impression of your tooth.
  • Install a temporary crown over your tooth.
  • Get a dental lab make the impressions of the crown.
  • Tell you to go back to their office after the new crown has been made so that it can be cemented to your tooth.

Same-day installation

The dentist will use this procedure:

  • Examine your teeth, take digital images, and brace your tooth for a treatment that may require the application of local anesthetics.
  • Using the automated scan of your images to create a crown in the office.
  • Cement the crown into place.

How long will I use the crowns of zirconia?

You can have them for years if you have them tested regularly. As teeth are living tissue, you can find variations in their form over time due to wear and tear. These modifications are not found in the crowns of zirconia. However, in order to adapt to the shifts, they will need to be replaced.

Will the repair hurt my teeth?

Since the crowns are trimmed, you won’t feel any pain. Zirconium does not cause tissue damage on the teeth.

How much material is lost during the procedure?

Substance loss is much less than the metal-enhanced porcelain crowns. Wear from 1 to 1,5 mm exists on the top of the teeth.

Would I feel some sort of pain during the operation?

The trim treatment is done under local anesthesia. When crowns are mounted, tingling caused by heat or cold can be avoided.

Would I have esthetic issues during treatment?

In fact, the temporary crowns mounted on your front teeth will be identical to your permanent zirconium crowns in shape. These crowns, which are made of plastic, are not fracture-resistant; however, their color and form are significantly identical to the natural teeth.
