The Role of Zirconia Crown in Modern Dentistry

zirconia crown

Modern dentistry is embracing zirconia crowns because they are incredibly strong, look great, and are safe for your mouth. These crowns provide strength, protection, and a nice appearance by covering the entire visible part of a damaged or decayed tooth.

Zirconia crowns are becoming more popular in today's dental practices because they offer many advantages over traditional crown materials like porcelain-fused-to-metal (PFM) crowns.

Composition of Zirconia Crown:

Zirconia crowns are dental restorations made from zirconium dioxide. This material is tough and long-lasting in nature, making it an ideal choice for dental crowns. What sets zirconia crowns apart is their composition and the way they are made. These crowns are made from a special kind of zirconium dioxide, which is translucent in nature. This translucency allows light to pass through the crown, making them look like natural teeth. This quality is important for dental work that can be seen easily, like fixing the front teeth of your mouth.

To make them stronger and more stable, tiny amounts of stabilizing oxides like yttria are added. These stabilizing oxides are what make the crown long-lasting and resistant to breaking.

Key Advantages of Zirconia Crown:

  1. 1. Aesthetics: The biggest advantage of Zirconia crowns is that they look very natural, just like real teeth. This is because they let high amounts of light pass through, like natural tooth enamel. They can match the colour and shade of the nearby teeth really well, making them blend in easily with your smile. That's why they're great for areas of your mouth where appearance is important, like the front teeth.
  2. 2. Strength and Durability: Another impressive quality of Zirconia crowns is how they have incredible strength and resistance to chipping, cracking, and wear. Zirconia crowns are stronger and more resistant to breakage than PFM crowns. This makes zirconia crowns suitable for both front and back teeth, where chewing forces are more. They have a special crystal structure that makes them extra tough. That's why they're a good choice if you tend to grind or clench your teeth a lot or if there's a lot of pressure on your teeth when you bite down.
  3. 3. Biocompatibility: Zirconia is safe for the human body and has no harmful effects. Patients with metal allergies or sensitivities can use it because it does not irritate oral tissues. Zirconia crowns don't include metals that could cause allergies. Additionally, they do not result in gum darkening, which is a problem with some metal-based restorations.
  4. 4. Stain Resistance: Zirconia crowns cannot get stained. They have a highly polished, smudge-free surface. Zirconia crowns don't stain easily because their structure doesn't have any tiny pores or spaces where stains can get absorbed. In addition, Zirconia doesn't react with substances in your mouth like acids, so it won't change colour over time.

The colour of zirconia crowns is customized to match your natural tooth colour, and it stays the same shade for a long time, keeping your smile looking great.

Comparison of Zirconia Crowns with other crowns:

Crown Type Material Strength Aesthetics Durability Preparation Suitability
Zirconia Crown Zirconia Very High High Very High Minimal General
PFM crown Metal + Porcelain High High Moderate Moderate General
Emax crown Lithium Disilicate High Very High Moderate Moderate Aesthetically demanding
Metal crown Metal Alloy High Low(visible) Very High Moderate Molars
Porcelain crown Porcelain Moderate Moderate Moderate Moderate General
Veneers Composite Resin Low High Low Minimal Anterior Teeth
Ceramic Crowns Ceramic Moderate High Moderate Moderate General

Zirconia crowns are great because they don't need a big part of your natural tooth structure to be removed when getting them fitted. This helps to keep your natural tooth strong. They're a good choice for most people because they're strong, look good, and last a long time.

Other types of crowns, like porcelain-fused-to-metal (PFM) crowns, also look good and last a while but need a bit more of your tooth to be prepared. Emax crowns resemble natural teeth very closely but aren't as tough as other crowns. Metal crowns are super strong but can be easily seen and don't look as nice. Porcelain crowns are okay in terms of strength and appearance. When it comes to crowns, there are lots of options, and it's best to talk to your dentist to find out which one is right for you.

Who Is an Ideal Candidate for a Zirconia Crown?

  1. Individuals with decayed, chipped or broken teeth cannot be treated with dental fillings or other treatments.
  2. Individuals with discoloured, dark, and stained teeth who want restorations that resemble their natural teeth.
  3. Individuals with a large cavity or a missing tooth require a dental crown like a Zirconia crown to restore the look and function of their natural tooth.
  4. Individuals with unevenly spaced teeth with large gaps, especially in the front region of the mouth.
  5. Individuals who have crooked, rotated or misshapen teeth.
  6. Individuals who have allergies to metals or other dental materials may find Zirconia crowns suitable, as Zirconia is biocompatible and does not cause any allergic reaction.
  7. Individuals looking for crowns requiring minimal tooth preparation and preserving more natural tooth structure may benefit from Zirconia crowns.
  8. Individuals who grind or clench their teeth or have other habits that cause their teeth to wear off may find zirconia crowns favourable due to their high strength and resistance to wear.
