Efficient and reliable – The one and only All-on-4®
by: Jim MackThere is only one proven All-on-4® treatment concept that provides edentulous and soon-to-be edentulous patients with an efficient and effective restoration using four implants to support an immediately delivered full-arch prosthesis.
After the first dental implant patient was treated in 1965, a discussion began around the optimal number of implants needed to anchor a fixed dental prosthesis in edentulous patients. Some clinicians tended to install as many implants as possible, often one per tooth. Others argued that biomechanically, only four or even three were needed. Only long-term clinical data could provide answers.

At the forefront
The records of the early patients of P-I Brånemark allowed for an early retrospective study.1 After a 10-year observation period, the survival rates were demonstrated to be the same for restorations with four and six implants. The challenge of advanced resorption remained, however. Because it is not possible in many cases to insert distal implants without grafting and/or nerve lateralization, the concept of tilting the two distal implants was introduced.
Immediate results

Today, the All-on-4® treatment concept is used around the world with similar high survival rates and patient satisfaction that is enhanced by limited costs.
