How Long Do All-on-4® Dental Implants Last?

All-on-4 treatment done 7 years ago

When people start exploring All-on-4® dental implants, one of the first questions they ask is: 

“How long will they last?” 

And it makes sense, this is a life-changing treatment and a big investment in both your health and confidence.

In this article, we’ll cover what makes All-on-4® implants last and how you can care for your smile to keep it strong for years.

What is All-on-4® Dental Implants? 

Before exploring the longevity of All-on-4® dental implants, it’s important to first understand what the procedure involves.

Unlike traditional implants that replace each missing tooth one by one, All-on-4® uses just four implants to support a full set of teeth. These implants hold a fixed bridge of natural-looking teeth that don’t move, don’t need to be removed, and look and feel like your own.

The implants are placed at precise angles to make the most of your existing bone. This means no bone grafting is needed, while giving you a strong and stable foundation.

So, How Long Do All-on-4® Dental Implants Last?

The simple answer is: All-on-4® dental implants can last 20 years or more — and even though this technology has only existed for 20 plus years, if we were to extrapolate the results of long term studies, they can even last a lifetime— when cared for properly.

These implants are trusted because they’re supported by decades of clinical research. Nobel Biocare, the original creators, have some of the longest and most reliable success studies available.

That said, the longevity of All-on-4® depends on a few key factors:

1. Quality of the Implant and Materials

We only use authentic Nobel Biocare implants in our clinic. These are top-tier implants with proven long-term success and durability. The material and design of your final teeth — whether acrylic, zirconia, or titanium-reinforced — also affect lifespan and wear.

2. Skill and Precision in Surgery and Planning

All-on-4® is a highly skilled technique. The way implants are placed — including their angle, depth, and position — makes a huge difference. At The Point Dental, we use advanced 3D imaging (CBCT scans) to precisely plan every step before surgery, ensuring a strong and lasting foundation for your new teeth.

3. Patient Health and Habits

Like your natural teeth, implants require good oral hygiene and healthy habits to last. Smoking, uncontrolled diabetes, or poor dental care can impact the health of your gums and bone, which can affect the longevity of your implants.

4. Regular Maintenance and Follow-up

Just like your natural teeth, All-on-4® implants need regular check-ups and professional cleanings. We recommend six-monthly hygiene visits to monitor your implants, check for any issues, and keep everything in optimal condition.

Durability of Final All-on-4® Bridge

The implants themselves integrate with your bone and can last decades. The prosthetic teeth (the bridge) attached to the implants may wear over time and might need replacement or repair after 5 -15 years, depending on your chosen materials and functional habits, for example night time grinding, excessive eating of hard food.

We take the time to craft your final bridge carefully for durability and aesthetics, but it’s normal to expect some maintenance down the line, similar to how you might replace worn shoes.

Real Patient Experience

I’ve seen many patients who’ve had their All-on-4® implants for years with no issues. One patient who had their treatment completed 7 years ago just came in for their regular hygiene maintenance told me:

“This was still the best decision they have made so far.”

That’s what we aim for: a long-term, life-changing solution — not just a quick fix.
