Nobel Biocare – All-on-4 treatment concept


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

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.

What is the All-on-4 treatment concept?

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.

  • bone grafting is avoided by tilting the posterior implants, utilizing available bone

Celebrating 25 years All-on-4

2023 marks a quarter century since the first scientifically documented clinical case of the All-on-4 treatment concept. First launched by Nobel Biocare, it is the only fixed full-arch treatment with 25 years of documented clinical success, which brought a revolutionary way of providing patients with a cost-efficient, graftless solution for fixed full-arch prostheses on the day of surgery, on just four implants.
