Nobel Biocare awards Dr. Paulo Malo for 25 years of the All-on-4® treatment concept

January 16 2023, Zurich, Switzerland

Dr. Paulo Malo has been presented a Quarter Century Award from Nobel Biocare, honoring the twenty-fifth anniversary of the revolutionary All-on-4® treatment concept. At a gathering in Nobel Biocare’s Dental Experience Center in Zurich, Switzerland, company President, Patrik Eriksson presented the trophy. 

Dr. Paulo Malo led the development of this treatment protocol in the early nineteen-nineties, with much-valued support from the late Dr. Bo Rangert of Nobel Biocare. In 1998, he treated the first patient documented in the first scientific study1, with the final version of the concept that became commercially launched.

The All-on-4® treatment concept is widely recognized as one of the most significant developments in implant dentistry. It 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.

With edentulism estimated to affect over 350 million people globally2, implant-supported restorations are recognized as one of the optimal treatment solutions.3 The All-on-4® treatment concept is one of the best-documented restorative solutions for edentulous patients, proven to provide clinically successful long-term outcomes.4,5

Dr. Malo said “In the early years of the All-on-4® treatment concept, very few people believed that it was possible. But I was seeing firsthand how successful the technique was for my patients and became completely dedicated to making it available for more people who suffer from edentulism. Twenty-five years ago, it was beyond my wildest dreams that it would reach the scale that it has today.”

He continued “This level of impact is all thanks to Nobel Biocare. They could see its true potential despite skepticism in the industry, and they took it to a global level like no other company would.”

Patrik Eriksson, President of Nobel Biocare said “I’m delighted to award Dr. Malo in recognition of this milestone. While many companies have tried to copy the All-on-4® treatment concept, Dr. Malo and Nobel Biocare have focused on pushing the boundaries to improve the products and further develop the end-to-end workflow.”

He concluded, “Together, we continue taking the lead for the future of the All-on-4® treatment concept.”

Throughout 2023 there will be a series of events to mark the twenty-fifth anniversary, including training courses, webinars and the continuation of the All-on-4® Center of Excellence program, which awards practices that have distinguished experience in, and loyalty to, the genuine All-on-4® treatment concept.


The All-on-4® treatment concept from Nobel Biocare is the original graftless full-arch solution on four implants. It provides a fixed full-arch prosthesis on the day of surgery6,7 for patients who meet the criteria for immediate loading. The prosthesis is placed on two straight implants in the anterior and two tilted implants in the posterior. Tilted implants are key to the concept, as they maximize the use of the existing bone to eliminate the need for bone grafting. This enables a shorter treatment time and reduced costs compared to conventional full-arch treatments.8 The All-on-4® treatment concept was launched commercially by Nobel Biocare in 2004 and over 250,000 patients have since been treated.9
