If you’re missing multiple teeth—or facing the reality of full-arch tooth loss—you may feel overwhelmed by your options. Traditional dentures? Costly full-mouth implants? Fortunately, there’s a proven solution that combines comfort, efficiency, and long-term results: the All-on-4® dental implant system.
But how well does it really work?
Let’s take a deep dive into what patients (and science) say about All-on-4, including a landmark study that revealed a 94.8% success rate after 10 years.
What Is All-on-4?
The All-on-4 dental implant technique allows for the full restoration of a missing upper or lower arch of teeth using just four strategically placed implants.
Unlike traditional full-mouth dental implants (which may require 6–10 per arch), All-on-4:
- Uses two vertical implants in the front
- And two angled implants in the back to maximize bone contact
- Often avoids the need for bone grafts
- Is designed for same-day tooth placement in many cases
This method was developed by Dr. Paulo Maló in collaboration with Nobel Biocare in the 1990s—and has revolutionized full-arch rehabilitation since.
The Study: 94.8% Success After 10 Years
In a long-term clinical study published by Dr. Maló and his team in the Journal of the American Dental Association, researchers followed patients who received All-on-4 treatment.
The findings:
- 245 patients with a total of 980 implants were monitored for 10 years
- Cumulative implant survival rate: 94.8%
- Prosthesis survival rate (how long the full arch of teeth lasted): 99.2%
- Very low complication rate, with most issues easily corrected
What does this mean for you?
It means if you’re a candidate for All-on-4, the odds are overwhelmingly in your favor for long-term success—with results that both look and feel like natural teeth.
Benefits of All-on-4 Implants
Here’s why more patients and clinicians are choosing All-on-4 over traditional options:
1. Immediate Results
In many cases, patients leave the office the same day with a fixed temporary prosthesis—no waiting months for teeth.
2. Avoid Bone Grafting
Because the rear implants are angled, they avoid areas of low bone density, often eliminating the need for sinus lifts or grafting.
3. Natural Look and Feel
All-on-4 implants are fixed in place, so they don’t shift or slip like removable dentures.
4. Lower Cost
Fewer implants = lower surgical and material costs than traditional full-arch restoration.
Are There Risks?
Like any dental procedure, All-on-4 carries some risks:
- Peri-implantitis: An inflammatory condition that can compromise implant success if not managed early.
- Mechanical wear: Over time, the prosthetic teeth may require maintenance or replacement.
- Hygiene and follow-up: Patients must commit to good oral hygiene and regular dental visits.
However, with proper care, most patients experience stable, functional, and aesthetic results for a decade or more.
Are You a Candidate for All-on-4?
You may qualify for All-on-4 if:
- You’re missing most or all of your teeth in one arch
- You wear dentures and are looking for a permanent upgrade
- You have moderate bone loss but want to avoid grafting
- You want fixed teeth that don’t come out at night
