Full Arch Restoration
All-on-4 Dental Implants London
A full arch of fixed, permanent teeth — supported by just four implants. All-on-4 is designed for patients with extensive tooth loss or severe bone loss, and often requires no bone grafting at all.
What Is All-on-4?
Four Implants. A Complete Smile.
All-on-4 is a revolutionary dental implant technique that restores a full arch of missing teeth using only four implants per jaw. Two implants are placed vertically at the front of the jaw, and two are placed at a strategic angle at the back — maximising contact with available bone and avoiding the need for sinus lifting in most cases.
This approach is particularly suitable for patients who have experienced significant bone loss and would not be eligible for conventional implants. The angled placement of the posterior implants compensates for reduced bone volume and provides a secure, stable foundation for the prosthesis.
A temporary fixed prosthesis is attached within 48 hours of surgery. You leave the clinic with teeth — and you are never without them at any stage of treatment.
Is It Right for You?
Who Is a Candidate for All-on-4?
- —Complete tooth loss in one or both jaws
- —Insufficient bone volume for conventional implants
- —Patients unable to undergo sinus lifting or bone grafting
- —Those seeking a permanent alternative to removable dentures
- —Patients with a strong gag reflex who struggle with removable prosthetics
Key Advantage vs All-on-6
Ideal for Bone Loss
All-on-4 uses angled implant placement to bypass areas of reduced bone density — making it the preferred solution for patients who have experienced significant bone loss and would not be suitable for All-on-6.
In most cases, no bone grafting or sinus lifting is required — reducing surgical complexity, recovery time and overall treatment cost.
