Treatment

All-on-4 & All-on-6

A complete, fixed set of teeth supported by four or six implants — a long-term alternative to dentures.

What it is

Understanding all-on-4 & all-on-6.

All-on-4 and All-on-6 are full-arch solutions that replace a whole upper or lower set of teeth using just four or six implants as anchors. The implants are positioned to make the most of the available bone, supporting a fixed bridge of teeth.

It's designed for people who have lost most or all of their teeth, or whose remaining teeth cannot be saved — offering a stable, fixed result rather than a removable denture.

Who it's for

You may be suitable if

  • You're missing most or all of the teeth in one or both jaws
  • You wear a denture and want something fixed and stable
  • Your remaining teeth are failing and need replacing
  • You have enough bone to support full-arch implants (assessed at consultation)
  • You want to restore comfortable eating and a confident smile

We'll also consider

  • !Full-arch treatment is a significant procedure planned over several visits
  • !Temporary teeth are usually provided while you heal — final teeth come later
  • !Suitability depends on bone and general health
  • !Diligent cleaning and regular reviews are essential
  • !We'll discuss the risks and aftercare in full beforehand

Only an in-person assessment can confirm what's right for you — that's what your consultation is for.

How it works

Your treatment journey.

01

Consultation & 3D scan

We assess your jaw, bone and bite with 3D imaging and discuss your goals and options.

02

Digital planning

The full arch is planned digitally so implant positions and the new teeth are mapped in advance.

03

Implant placement

The implants are placed and, in many cases, a fixed set of temporary teeth is fitted while you heal.

04

Final teeth & aftercare

Once integrated, your definitive bridge is fitted, and we set up a long-term care and review plan.

FAQ

Common questions.

Is it the same as 'teeth in a day'?

Many full-arch cases allow a fixed set of temporary teeth to be fitted shortly after surgery, with the definitive teeth made once healing is complete. Whether this suits your case is confirmed at your planning appointment.

All-on-4 or All-on-6 — which do I need?

It depends on your bone volume and bite; more implants can provide additional support in some cases. We recommend the most appropriate option after your 3D assessment.

How much does full-arch treatment cost?

Cost depends on the number of arches, implants and materials involved. We provide a detailed written quote after your consultation, with no obligation.

How do I clean them?

Fixed full-arch teeth are cleaned daily much like natural teeth, with some additional aids we'll show you. Regular professional reviews keep everything healthy.

How long does the whole process take?

Timescales vary between individuals because healing differs. We'll give you a realistic, personalised timeline at your planning appointment.

By the numbers

The wider picture.

Around 1 in 10 adults aged 75+ in England have no natural teeth, and tooth loss increases steadily with age.

Source: Adult Oral Health Survey 2023 (OHID, GOV.UK)

The proportion of adults in England with no natural teeth has fallen from 28% in 1978 to 2.5% today — more people now keep or replace teeth rather than go without.
