All-on-4 vs All-on-6: What's the Difference?

How All-on-4 and All-on-6 full-arch implant bridges compare, why your jawbone matters, and what the two-visit process involves.

The same idea, a different number of implants

Both replace a full arch of teeth with a fixed bridge held in place by dental implants: four implants for All-on-4 and six for All-on-6. Unlike a removable denture, the bridge is fixed and is only taken out by a dentist.

How the dentist chooses

The choice depends on how much healthy jawbone you have, where it is, and your bite. The dentist decides after examining your X-rays and your mouth; some people need a bone graft first.

Neither option is better for everyone, and the dentist may recommend a different solution altogether.

Why it takes two trips

Implants need time to fuse with the jawbone, usually around four months, before the final bridge is fitted. Full-arch treatment therefore usually means one visit to place the implants (often with a temporary bridge), healing at home, and a second visit for the final bridge.

Looking after a full-arch bridge

There's no lifetime guarantee. Cleaning around the implants and regular check-ups with a dentist help prevent gum problems that can lead to implants loosening.
