All-on-6 Dental Implants - UK Guide 2026

Who is this treatment for?

Ideal for patients who need a full fixed arch but have reduced bone density, a strong bite (bruxism), or who want extra mechanical safety margin beyond a standard All-on-4. Also commonly used for full mouth reconstructions where the patient values long-term load distribution.

How the treatment works, step by step

1. 01

   Full mouth assessment and 3D planning

   A specialist implantologist reviews a full mouth examination, CBCT scan, and digital impressions to plan the optimum position of six implants. Failing teeth in the arch are usually extracted on the day of surgery.

2. 02

   Implant placement and immediate bridge

   Six implants are placed in the arch under local anaesthetic with optional sedation. The extra two implants add around 30 to 45 minutes to the surgical time compared to All-on-4. A fixed temporary bridge is typically attached the same day.

3. 03

   Healing (3-6 months)

   Bone integrates with all six implants over several months. The distributed load across six fixtures reduces the stress on any single implant, which can improve long-term success rates in higher-risk cases.

4. 04

   Final fixed bridge

   Once healing is complete, a permanent bridge in zirconia, acrylic-titanium hybrid, or porcelain-metal is fitted. The bridge is custom-made to match the patient's face, smile line, bite, and phonetic needs.

What's included in a typical private quote

• Full mouth clinical examination and CBCT scan
• Digital smile design and treatment planning
• Surgical placement of six titanium implants per arch
• Necessary extractions of failing teeth on the day
• Same-day fixed temporary bridge
• Final fixed bridge (zirconia or hybrid)
• Sedation where clinically appropriate
• Review appointments and warranty

Common add-ons that affect the price

These are the most common items that may raise the final quote. A good consultation will tell you which of these apply to your case before you commit.

• Bone graft (per site) £300 - £1,200
• Sinus lift (upper arch) £1,000 - £2,500
• IV sedation £350 - £800
• Upgraded zirconia bridge £1,500 - £4,000

Are you a good candidate?

Most UK patients can have this treatment, but the following factors make a difference to clinical planning and long-term success:

• Full arch of missing or failing teeth
• Reduced bone density or higher mechanical load expected
• Bruxism (teeth grinding) or strong bite forces
• Non-smoker or willing to stop during healing
• Good general health, controlled medical conditions

All-on-6 vs All-on-4: when the extra two implants matter

All-on-4 and All-on-6 are the same treatment concept - a full fixed arch of teeth supported by implants - but with different mechanical margins. All-on-4 uses four implants per arch, usually placed at specific angles to maximise bone contact. All-on-6 adds two more implants, which distributes chewing forces across a larger number of anchor points.

For most patients with adequate bone density and a standard bite, the clinical outcome of All-on-4 is excellent and the extra cost of All-on-6 is not justified. But in specific cases, the additional mechanical safety margin is worth the 15 to 25 percent price increase. The clearest indications for All-on-6 are:

• Reduced bone density where individual implants would be more heavily loaded than ideal, typically in older patients or long-term denture wearers with significant jawbone atrophy.
• Bruxism or heavy bite forces, where teeth grinding puts unusual stress on the bridge and implants over time. Six implants handle repetitive load better than four.
• Larger jaws or wider arches, where spreading the load across six fixtures creates a more balanced and biomechanically stable final bridge.
• Patient preference for additional redundancy, particularly for patients who want the longest possible lifespan and are comfortable paying the upgrade cost.

The decision between All-on-4 and All-on-6 should always be made at the planning stage, after a CBCT scan and a conversation with the implant dentist about your specific bite, bone, and medical history. A good clinic will not push you toward the more expensive option without a clinical reason.

Typical UK pricing for All-on-6 in 2026

In 2026, the UK private market prices All-on-6 at approximately £11,500 to £17,000 per arch, with an average around £14,000. This is about 15 to 20 percent higher than All-on-4 for the same clinic, reflecting the extra implant fixtures, additional surgical time, and the more complex bridge design.

For a full mouth case (both arches), All-on-6 comes in at £23,000 to £32,000, compared to £18,000 to £28,000 for All-on-4. The absolute difference of £4,000 to £5,000 per case can be significant, but for the right patient, it buys a materially more durable result.

Is same-day loading still possible with six implants?

Yes. All-on-6 follows the same "teeth in a day" protocol as All-on-4: the six implants are placed in the morning, and a fixed temporary bridge is attached the same day so the patient leaves with a full functional set of teeth. The temporary bridge is worn through the 3 to 6 month healing phase, and replaced with the final permanent bridge once osseointegration is complete.

The extra two implants do add around 30 to 45 minutes of surgical time compared to All-on-4. Most UK clinics still complete the full treatment in a single morning session, often with optional sedation.

Long-term success rates and warranty

Peer-reviewed UK and European data suggests that All-on-6 achieves 10-year implant survival rates of 95 to 98 percent in well-selected cases, marginally higher than All-on-4 for patients with the risk factors listed above. For patients with good bone and a normal bite, both techniques perform similarly.

Most UK private clinics offer a warranty of 3 to 5 years on the final bridge and 10 to 15 years on the titanium fixtures. Ask for the warranty in writing before you commit, and make sure it covers the loss of any single implant during the warranty period, not just mechanical failure of the fixture itself.
