Zirconia Teeth Implants

What is Zirconia Made From?

Zirconia, short for zirconium dioxide, is a ceramic material made by combining zirconium (a metal) with oxygen. Once oxidized, zirconium loses its metallic properties and becomes a ceramic that’s both incredibly strong and resistant to heat and corrosion. It offers a metal-level durability with the clean, aesthetic look of ceramic. That’s why zirconia is used not only in dentistry but also in aerospace, jewelry, and even industrial tools.

How is Zirconia Used in Dental Implants?

For dental implants, zirconia can be used in two ways:

• Implant Post (the root replacement): Instead of titanium, some dentists use a zirconia implant post. This sits inside your jawbone and acts like a new tooth root. Patients who prefer metal-free dentistry often ask for this option.
• Permanent Teeth / Crown (the visible tooth): Zirconia crowns are extremely common and well-established. They cap either a natural tooth or an implant and are known for their strength, natural appearance, and resistance to plaque.

The key is not to confuse the two. A “zirconia tooth” usually means a crown, while a “zirconia implant” refers to the root-like post in your jaw.

Comparing Teeth Materials: Zirconia, ZIRPEEK® vs. Other Options

When it comes to dental crowns (the teeth part), there are a few options:

• Zirconia offers a natural tooth-like color, high durability, and lower plaque buildup.
• ZIRPEEK® is a newer material that offers an advanced four-layer design incorporating platinum, zirconia as well as resin and a high-performance polymer that combines strength, flexibility, natural feel as well as less weight than zirconia.
• Porcelain-fused-to-metal crowns can look good but sometimes show dark lines at the gums over time.
• Full-metal crowns (like gold) are strong but not aesthetic.

At Smart Arches, we choose Zirconia as well as ZIRPEEK® because they blend in seamlessly, are extremely durable and hold up under chewing forces.

Comparing Implant Materials: Zirconia vs. Titanium

For the implant post itself, titanium has been the gold standard since the 1960s. It’s extremely well-studied, with survival rates over 90% and decades of research backing its safety and effectiveness.

Zirconia, on the other hand, is newer to the U.S. (FDA-approved in 2011). Early studies show promising results for bone integration and gum health, and many patients are drawn to its white, metal-free appearance. But the long-term data just isn’t as extensive as titanium yet. Here’s how they compare:

Titanium Implants

• Pros:
  • Decades of proven success with long-term survival rates over 90%
  • Two-piece systems allow angled abutments for complex cases
  • Strong, corrosion-resistant, and excellent bone integration
  • Lower failure rates compared to zirconia
• Cons:
  • Can sometimes show a grayish hue through thin or receding gums
  • May attract more plaque than zirconia
  • Rare cases of metal allergy or sensitivity

Zirconia Implants

• Pros:
  • Biocompatible and hypoallergenic — a good option for patients with metal sensitivity
  • Naturally white for superior aesthetics (especially in front teeth)
  • Smooth, non-polar surface resists plaque and bacterial buildup
  • Corrosion-resistant and tissue-friendly with good bone integration
• Cons:
  • Limited long-term research compared to titanium
  • Typically only available as one-piece systems, limiting customization
  • Limited restoration options
  • Difficult to adjust after placement as grinding can weaken fracture resistance
  • Potential for “material aging” over time, leading to small cracks
  • May have higher failure rates than titanium in some studies

At Smart Arches, we rely on titanium for implant posts because of its unmatched track record, long-term reliability, and flexibility for a wide range of patient needs. Zirconia is an exciting alternative for specific cases, but titanium remains the most trusted choice.

Is Zirconia a Safe Material?

Zirconia is a safe, bioinert, non-corrosive, and hypoallergenic material. The use of zirconia in teeth have decades of of use, while the use of zirconia in implants is relatively newer with less long-term studies, which is why at Smart Arches we use zirconia for permanent teeth and titanium for the implant post.

How Long Does Zirconia Last?

Again, we need to differentiate between zirconia used for the crown vs the implant itself.

Zirconia Crowns / Zirconia Teeth (the part you actually see)

• Typical lifespan: 10–15 years on average, but with good care they can last 20 years or more.
• Why they last so long: Zirconia is one of the strongest materials used in dentistry, and it’s highly resistant to cracking, chipping, and wear. Unlike porcelain-fused-to-metal crowns, there’s no risk of the porcelain layer breaking away.
• Factors that shorten lifespan: teeth grinding, chewing ice/hard foods, poor oral hygiene, or gum disease.
• Studies: Many dentists report survival rates above 90% at 10 years, which is excellent compared to other crown materials.

Zirconia Implant Posts (the root replacement)

• These don’t have as much long-term data yet. Studies show 5–10 year survival rates comparable to titanium, but they haven’t been around long enough in the U.S. to have 20–30 year studies.
