All-on-4® treatment concept

A minimally invasive solution with a fixed full-arch restoration for high patient satisfaction


video coming soon

In 1998 Dr. Paulo Malo successfully treated the first patient with the All-on-4® treatment concept. Since then hundreds of thousands of patients have been treated with this concept using Nobel Biocare implants.

The All-on-4® treatment concept is the best solution for full-arch treatment using tilted implants. But only when Nobel Biocare products are combined. Many have tried to mirror this groundbreaking concept, but only we have the scientifically documented success to back it up.

The All-on-4® treatment concept is a cost-efficient, graftless solution that provides patients with a fixed full-arch prosthesis on the day of surgery.

Characteristics include:

  • Full-arch rehabilitation with only four implants
    Two straight anterior implants and two implants tilted up to 45º in the posterior
  • Immediate Function (fixed provisional bridge)
    For patients meeting criteria for immediate loading of implants
  • Graftless procedure
    Bone grafting is avoided by tilting the posterior implants, utilizing available bone

Why 98% of patients would recommend the All-on-4® treatment concept1

Rapid improvement in quality of life
A fixed full-arch prosthesis on the day of surgery quickly leads to improved patient satisfaction – with regards to function, esthetics, sense, speech and self-esteem2,3.

Shorter treatment times
Tilting of the posterior implants avoids the need for time-consuming bone grafting procedures, while immediate loading shortens time-to-teeth4.

Lower costs
The concept is the least costly in comparison with conventional implant treatment modalities of the edentulous and soon-to-be edentulous jaw5.

Patients with terminal dentition

A significant number of cases treated with the All-on-4® treatment concept are patients with failing dentition.

“Two thirds of patients we treat in our practice with full-arch restorations are soon-to-be edentulous patients.”
Dr. Wolfgang Bolz, Germany

Patients with edentulism are also often eligible for the All-on-4® treatment concept. A thorough evaluation of any patient is necessary in order to choose the right treatment and to establish a predictable treatment outcome. In our new e-book you will find four steps to help you identify the right patient and recommendations for treatment planning.

Proven long-term solution with high survival rates

The All-on-4® treatment concept is a proven long-term solution with up to 10 years follow-up in the mandible and 5 years in the maxilla.5,6

Cumulative survival rates are high in both the edentulous maxilla and mandible.
2, 3, 5, 6, 7, 8, 9, 10
Mid-term 3–4 years: 96.3–100%3,9,10
Long-term 5–10 years: 94.8–98.0%5,6

What Patients Say

"I always had problems with my teeth and oral health in general. My dentist was a real life-saver. My teeth feel like my own—so secure,
that I know I never have to worry about them ever again. Getting
implants is the best decision I have ever made!"

Pat Farrell, US

"For much of my life, I suffered from gum disease, bone loss and unstable teeth. I was very self-conscious about my situation and thought that there was no solution to my problem. I cannot believe the difference All-on-4 has made in my life."

Carole Lane, UK




What Users Say

"The use of four implants reduces treatment complexity, which yields many benefits. Costs for both the doctor and the patient are reduced because less surgical time and products are used. The lab technician can profit from reduced intricacy in the fabrication of the prosthesis – leading directly to more predictable workflow patterns. And simplified hygiene bodes well for improved long-term oral health all around."

Prof. Paulo Malo, Portugal

"Thanks to All-on-4, I can avoid lengthy and unpredictable bone grafting procedures. Patients with removable dentures tend to have a certain age. It makes a world of difference to them whether they get fully functioning teeth on the day of surgery or a year later."

Dr. Larry Benge, Australia

"All-on-4 has helped me increase my patient base substantially. I can offer a life-changing and cost-effective method that allows more patient to have proper implant treatment."

Dr. Antony Carbery, Canada

"With no other procedure that I offer is the increase in quality of life as apparent as with All-on-4. The patients enter my practice with misfitting and often painful removable dentures and leave the same day with a fixed implant-based provisional restoration that looks and feels like a full set of natural teeth."

Dr. Enrico Agliardi, Italy

"After more than 20 years in the field of implant dentistry, the All-on-4 technology now allows me to offer my patients a simple, predictable, and accessible treatment. There is no reason to tolerate unstable prostheses."

Dr. Thierry Dhuyser, Canada
