All-on-4 is a full-arch implant solution that has transformed the treatment of patients with significant tooth loss. For patients who have lost most or all of their teeth, or who are facing the prospect of dentures, all-on-4 offers a fixed, non-removable alternative that looks and functions like a natural set of teeth.
All-on-4 is a technique in which four dental implants are placed strategically across the arch to support a full set of fixed replacement teeth. The two posterior implants are placed at an angle of up to 45 degrees, which allows them to be positioned in bone that is naturally denser and avoids the need for bone grafting in most cases.
The prosthesis, typically an acrylic or zirconia arch of replacement teeth, is attached to the four implants and remains fixed in the mouth. Unlike a traditional denture, it cannot be removed by the patient. It is cleaned in the same way as natural teeth.
It is not the right solution for everyone. A thorough clinical assessment, including a CBCT scan with our carestream cs 8200, is essential before any recommendation is made.
All-on-4 treatment is a significant investment. In the UK in 2026, full-arch all-on-4 treatment typically ranges from £12,000 to £25,000 per arch. Cost varies depending on the materials used for the final prosthesis and the complexity of the case.
At Berkhamsted Dental, we provide a complete treatment plan and transparent fee breakdown at your consultation before any decision is made. We also offer 0% finance options through tabeo to help spread the cost.
Fixed and secure. All-on-4 prostheses are fixed in place. There is no movement during eating or speaking, no adhesive required, and no need to remove them at night.
Bone stimulation. Because the implants are anchored in the bone, they stimulate bone maintenance. Dentures do not, and bone loss under a denture progresses over time.
Natural function. Patients with all-on-4 can eat a full range of foods, including those that are difficult or impossible with conventional dentures.
Confidence. For many patients, the psychological difference between removable dentures and a fixed, beautiful set of teeth is transformative.
