All-on-4 vs All-on-6 Cost: What UK Patients Really Pay in 2026
Specialist Prosthodontist · Taki Dent, Antalya
When UK patients weigh up All-on-4 against All-on-6, cost is almost always the deciding practical factor. So let me give you the real 2026 numbers in pounds — the same figures I quote in consultation — and explain precisely what you are paying for when you choose six implants over four.
The headline difference
The simplest way to remember it: All-on-6 costs roughly £1,500–£2,500 more per arch than All-on-4. That gap is fairly consistent wherever you are treated. What changes dramatically is the base price — and that is where Turkey transforms the maths for UK patients.
2026 prices: Turkey vs UK
| Procedure | Turkey (per arch) | UK private (per arch) |
|---|---|---|
| All-on-4 | £4,500 – £7,500 | £10,000 – £16,000+ |
| All-on-6 | £6,000 – £9,500 | £14,000 – £22,000+ |
| All-on-4 (full mouth) | £9,000 – £14,000 | £20,000 – £30,000+ |
| All-on-6 (full mouth) | £12,000 – £18,000 | £28,000 – £42,000+ |
The pattern is striking. In the UK, stepping up to All-on-6 might add £4,000–£6,000 to a full-mouth bill. In Turkey, the same upgrade adds around £3,000–£4,000 to a total that is already 60–70% lower. For many of my UK patients, the entire All-on-6 premium is comfortably absorbed by the saving they make simply by travelling.
What the extra money actually buys
The All-on-6 premium is not a mark-up — it reflects real costs:
- Two additional premium implant fixtures (Straumann or Nobel Biocare fixtures alone are £300–£600 each in materials).
- Two more abutments and the additional surgical time to place them.
- A longer, more heavily reinforced bridge framework.
- Occasionally a sinus lift or minor graft, because All-on-6's upright posterior implants need more bone height than All-on-4's tilted ones.
That last point matters for budgeting: if your bone is borderline, All-on-6 may carry an extra grafting cost (£150–£900 per site) and a few months more healing. It is one reason I often recommend All-on-4 even when a patient arrives asking for "the one with more implants".
What should be included in a fair quote
An all-inclusive full-arch quote should cover the surgery, sedation where appropriate, the same-day temporary bridge, the final bridge, and follow-ups during your stay. Budget separately for return flights (£150–£350), extra hotel nights (£30–£70), and a sensible contingency of £500–£1,000. You can see the complete breakdown on our cost comparison page.
Beware the suspiciously cheap All-on-6
If an All-on-6 quote lands close to a budget All-on-4 price, treat it as a warning, not a bargain. The savings usually come from somewhere you do not want — unbranded implants, an acrylic-only bridge that wears faster, or surgery without proper sedation. Always confirm the implant brand, the final bridge material (zirconia is the gold standard) and exactly what is included before you compare two prices.
So which represents better value?
If your bone suits it and budget is tight, All-on-4 in Turkey is the most cost-effective fixed full-arch option there is — life-changing teeth from around £4,500 per arch. If you have the bone and a heavy bite, the All-on-6 premium buys durability that pays for itself by avoiding future repairs. The wrong move is choosing on price alone in either direction.

Frequently asked questions
How much more is All-on-6 than All-on-4?
In Turkey, roughly £1,500–£2,500 more per arch — about £6,000–£9,500 versus £4,500–£7,500. In the UK the gap is larger because base prices are 60–70% higher.
Why is All-on-6 more expensive?
Two extra implants and abutments, more surgical time, a longer reinforced bridge, and occasionally minor grafting because the upright posterior implants need more bone. It is a genuine cost, not a mark-up.
Is a cheaper All-on-6 quote a red flag?
It can be. A bargain All-on-6 often means cheaper implants, an acrylic-only bridge, or no sedation. Always check the implant brand, bridge material and inclusions before comparing.
