Zirconium Crowns

What Are Zirconium Crowns?

Zirconium crowns are a type of dental restoration made from a strong, white ceramic material called zirconium dioxide. They are popular for their durability, aesthetics, and biocompatibility. Compared to traditional porcelain crowns, zirconia crowns are more resistant to chipping and fracturing, and their natural translucence closely mimics the appearance of real teeth. Additionally, zirconium crowns are metal-free, which makes them a suitable option for patients with metal allergies and avoids a potential gray line at the gum margin that can sometimes occur with metal-based crowns.

Ideal Candidates for Zirconium Crowns

  • People Who Desire a Natural Look:  If you're concerned about the dark line sometimes seen with traditional crowns, zirconium is ideal. It mimics natural teeth perfectly, creating a seamless and aesthetically pleasing result.
  • Patients with Metal Allergies:  Zirconium's biocompatible nature makes it perfect for those with metal sensitivities. Unlike traditional crowns, it won't trigger any allergic reactions.
  • Those Seeking a Strong Yet Beautiful Restoration:  Zirconium offers exceptional strength, even exceeding some metal options. This ensures your crown can handle your bite force for years to come, while maintaining a beautiful appearance.
  • Individuals Who Want a Health-Conscious Choice:  The biocompatible nature of zirconium promotes healthy tissue integration around the crown. This can be ideal for patients who prioritize a holistic approach to healthcare.


Additionally, zirconium crowns can be a great choice for:

  • People with Damaged Teeth:  Cracks, fractures, or large cavities can all be effectively addressed with zirconium crowns, restoring the tooth's strength and functionality.
  • Those with Cosmetically Displeasing Teeth:  Zirconium crowns can address severe discoloration, misshapen teeth, or uneven smiles, creating a uniform and aesthetically pleasing look.

Advantages of Zirconium Crowns At Mediphora

  • Zirconium, devoid of metal components, prevents gingival discoloration at the gum line where the coating interfaces with the gums.
  • Zirconia crowns exhibit exceptional biological compatibility within the oral cavity, integrating seamlessly with surrounding tissues such as the gums, cheeks, lips, and tongue over extended periods.
  • Compared to other metal-free crowns, zirconium teeth offer heightened durability, boasting remarkable fracture resistance while maintaining aesthetic appeal.
  • Zirconium crowns require less tooth abrasion during preparation than metal-supported porcelains, attributed to the absence of metal in the sub-structure of the zirconium coating, thus preserving natural tooth structure.
  • The thin edges of zirconium veneers facilitate a smooth porcelain transition, ensuring a natural appearance without disturbing the gum line.
  • Utilizing Cad-Cam technology for precise production, zirconium teeth are accurately fitted to the prepared tooth, minimizing the risk of decay by effectively sealing the space between the crown and the tooth.
  • Notably, zirconium-based teeth are immune to allergic reactions, further enhancing their suitability for dental applications.

Before & Afters

Frequently Asked Questions

Are zirconium crowns more expensive than other types of crowns?

Zirconium crowns may be slightly more expensive than other types of crowns due to the material cost and fabrication process. However, the durability, aesthetics, and longevity of zirconium crowns can make them a cost-effective investment in the long run. Dental insurance may cover a portion of the cost of zirconium crowns, depending on the terms of your policy.

Can zirconium crowns cause any allergic reactions?

Zirconium crowns are made from biocompatible materials and are unlikely to cause allergic reactions in most patients. Zirconium oxide is hypoallergenic and does not contain any metal components that could trigger allergies or sensitivities, making it a safe option for individuals with metal allergies or sensitivities.

Do zirconium crowns require any special preparation of the tooth?

Like other types of crowns, zirconium crowns require the tooth to be prepared by removing a thin layer of enamel to accommodate the crown. Your dentist will carefully shape the tooth to create space for the crown and ensure a proper fit. The amount of tooth preparation may vary depending on factors such as the extent of damage or decay and the desired aesthetics.

Can zirconium crowns be used to cover dental implants placed for single-tooth replacement?

Yes, zirconium crowns can be used to cover dental implants placed for single-tooth replacement, providing a natural-looking and functional restoration. The crown is custom-made to match the size, shape, and color of the surrounding teeth, creating a seamless and aesthetically pleasing smile.

How can I ensure the longevity of my zirconium crowns?

To ensure the longevity of your zirconium crowns, it's essential to maintain good oral hygiene practices such as brushing twice a day, flossing daily, and visiting your dentist regularly for check-ups and cleanings. Avoiding habits that can damage the crowns, such as chewing on hard objects or grinding teeth, can also help prolong their lifespan.

How are zirconium crowns fabricated?

Zirconium crowns are custom-made using computer-aided design and computer-aided manufacturing (CAD/CAM) technology. After taking digital impressions of the tooth, a dental laboratory mills the zirconia material into a precise crown shape based on the digital design. The crown is then customized to match the color and characteristics of the patient's natural teeth before being bonded into place by the dentist.

Can zirconium crowns be used for front teeth?

Yes, zirconium crowns can be used to restore front teeth with excellent aesthetic results. Zirconium oxide closely resembles the appearance of natural tooth enamel, allowing for seamless integration with surrounding teeth. Zirconium crowns are highly translucent and can be customized to match the color and shape of adjacent teeth, creating a natural-looking smile.

Do zirconium crowns require special care?

Zirconium crowns do not require special care beyond regular oral hygiene practices such as brushing, flossing, and routine dental check-ups. It's essential to avoid habits that can damage the crown, such as biting on hard objects or using teeth as tools. Your dentist may recommend a non-abrasive toothpaste to prevent scratching the surface of the crown.
