All-on-4 is a full arch dental implant solution: a complete upper or lower set of teeth supported by just four strategically placed implants. It is the most common solution for patients who have lost most or all of their teeth in one jaw, and it eliminates the need for removable dentures. In the UK, All-on-4 costs £10,000–£18,000 per arch. Both arches (full mouth) typically cost £18,000–£28,000.
What Is All-on-4?
The All-on-4 technique was developed by Nobel Biocare and uses four dental implants per arch — two placed vertically at the front and two placed at an angle (45°) at the rear. The angled rear implants avoid the need for bone grafting in most cases, by anchoring into denser bone further forward in the jaw. A fixed bridge of 10–14 teeth is then attached to the four implants.
The result is a permanent, non-removable set of teeth that look, feel and function similarly to natural teeth. Patients can eat, speak and smile normally. Unlike dentures, All-on-4 requires no adhesive and stays in place overnight.
All-on-4 Costs in the UK
- Single arch (upper or lower) in UK: £10,000–£18,000
- Full mouth (both arches) in UK: £18,000–£28,000
- With bone grafting (if needed): add £800–£2,500
- All-on-4 in Poland: £5,000–£8,500 per arch
- All-on-4 in Hungary: £5,500–£9,000 per arch
- All-on-4 in Turkey: £3,000–£6,000 per arch
The wide price range within the UK reflects differences in implant brand, the number of teeth on the bridge (10 vs 12 vs 14), the material of the bridge (acrylic vs zirconia) and the seniority of the treating clinician.
Am I Suitable for All-on-4?
All-on-4 is typically recommended for patients who:
- Have lost most or all teeth in one or both jaws
- Are currently wearing full dentures or are about to lose their remaining teeth
- Have sufficient bone density in the front of the jaw (the angled rear implants avoid the need for bone grafting in most cases)
- Are in good general health — diabetes, smoking and certain medications affect implant success rates
- Want a permanent, non-removable solution
All-on-4 is not suitable for patients with very limited bone volume throughout the jaw (All-on-6 with bone grafting may be more appropriate), for patients with uncontrolled systemic conditions, or for children and young people.
The All-on-4 Process
- Consultation and planning: CBCT 3D scan, treatment planning, discussion of bridge material options (acrylic temporary, then zirconia permanent)
- Extraction day (if needed): Remaining teeth extracted
- Implant placement: Four implants placed under sedation or general anaesthetic (day procedure)
- Temporary bridge: A temporary acrylic bridge fitted the same day — ‘teeth in a day’
- Healing period: 3–6 months for implants to integrate
- Permanent bridge: Final zirconia bridge fitted once implants have fully integrated
All-on-4 vs Implant-Supported Dentures
An alternative to All-on-4 is implant-retained overdentures — a removable denture anchored to 2–4 implants. This costs significantly less (£3,000–£8,000 per arch) but is less stable than All-on-4 and still requires removal for cleaning. For patients who cannot afford All-on-4 or are not suitable candidates for fixed implants, overdentures are a worthwhile middle ground.
Frequently Asked Questions
How much does All-on-4 cost in the UK?
All-on-4 dental implants cost £10,000–£18,000 per arch (upper or lower) in the UK. Full mouth treatment (both arches) typically costs £18,000–£28,000. Dental tourism to Poland or Hungary can reduce this to £5,000–£9,000 per arch.
What is the difference between All-on-4 and All-on-6?
All-on-4 uses four implants per arch; All-on-6 uses six. All-on-6 provides additional support and is typically recommended when bone density is lower or when a wider bridge is needed. It costs more — approximately £14,000–£22,000 per arch in the UK.
How long do All-on-4 implants last?
The implant fixtures typically last 15–25 years or more. The bridge (the teeth attached to the implants) usually lasts 10–15 years before needing replacement. Zirconia bridges last longer than acrylic.
Can I get All-on-4 on finance in the UK?
Yes. Most UK practices offering All-on-4 arrange finance through providers such as Chrysalis Finance. A £14,000 All-on-4 case on 5-year finance at 9.9% APR costs approximately £300/month. 0% finance is sometimes available for shorter terms.
