Dr. Rubén Davó, from the Vithas Medimar Hospital, leads the first study that endorses the ‘Quad Zygoma’ as the definitive solution for failed maxillary implants

1. Published in the prestigious journal Clinical Oral Implants Research (COIR), the study offers clinical evidence after a follow-up of up to 17.5 years 

2. Research positions this technique as a reliable salvage therapy for complex cases of failure in implants of the entire upper arch

The first study on zygomatic implants of 2026 has recently been published in the scientific journal Clinical Oral Implants Research (COIR), which is now available in open access.  In it, Dr. Rubén Davó, maxillofacial surgeon at the Vithas Medimar Hospital and director of Vithas Davó Dental Institute, positions Spanish maxillofacial surgery and dentistry at the international forefront.

“This publication represents a milestone in providing the first robust, long-term clinical evidence that redefines the Quad Zygoma protocol. Research shows that this technique is a highly reliable rescue therapy for patients who have suffered the failure of previous rehabilitations of complete dentures, definitively overcoming the concept of being a simple alternative treatment,” explains Dr. Davó.

Scientific evidence

The study provides conclusive figures on the effectiveness of this intervention in critical cases. Thus, on a sample of 28 patients treated with a total of 112 zygomatic implants, an average follow-up of 8.2 years has been carried out, with documented cases of up to 17.5 years of evolution.

The survival rate of the implant has been 98.2% and in 100% of cases it was performed with an immediate function protocol, allowing the patient to recover function and aesthetics in record time.

“When conventional solutions fail and there are no longer clear alternatives, the patient is in a situation of extreme vulnerability. This study shows that Quad Zygoma is a highly predictable solution that restores quality of life in the long term,” says Dr. Rubén Davó.

A benchmark in complex surgery

Vithas Davó Dental Institute has thus established itself as a world reference centre for the resolution of complex failures in implantology. The results show that complications are manageable and do not compromise the ultimate success of rehabilitation.

For the scientific community, this work published in COIR sets a new standard, proving that the protocol, led by Dr. Davó, is the definitive answer when the rest of the options to recover fixed teeth have failed.
