All-on-6 dental implants use six implant posts per arch to support a full set of fixed replacement teeth. It is the step up from All-on-4 — more implants mean a wider distribution of load, which is particularly useful when bone density is good enough to support the extra posts. This guide covers UK costs, how it compares to All-on-4, and who is a suitable candidate.
All-on-6 vs All-on-4: What Is the Difference?
| Factor | All-on-4 | All-on-6 |
|---|---|---|
| Implants per arch | 4 | 6 |
| UK cost per arch | £8,000–£18,000 | £10,000–£22,000 |
| Bone volume needed | Less — angled implants compensate | More — ideally good posterior bone |
| Load distribution | Good | Better — more even spread |
| Suitable for heavy bite? | Yes, but some limitations | Better for high bite force patients |
| Cantilever (overhang) | Often present at back | Reduced or eliminated |
| Recovery time | 2–4 weeks for normal function | 2–4 weeks for normal function |
The practical difference for most patients is small. All-on-4 was designed specifically to minimise the need for bone grafting by using angled posterior implants — it has an excellent 20-year evidence base. All-on-6 is chosen when the patient has good bone volume, a heavy bite, or when the surgeon wants to reduce reliance on cantilever at the back of the arch.
Neither system is universally “better” — the right choice depends on your bone anatomy, bite force and the surgeon’s assessment. A clinic that only offers one option should raise questions.
All-on-6 Dental Implants Cost UK 2025
| Treatment | Cost Range UK | Notes |
|---|---|---|
| All-on-6 single arch | £10,000–£22,000 | Upper or lower — includes implants, bridge, temps |
| All-on-6 full mouth (both arches) | £20,000–£40,000 | Most common for full-mouth reconstruction |
| All-on-6 with zirconia bridge | £13,000–£26,000 | Most durable final restoration material |
| All-on-6 with acrylic bridge | £10,000–£18,000 | Lower cost, less durable long-term |
| All-on-6 abroad (Hungary/Poland) | £6,000–£10,000 per arch | Saves 40–55% net of travel costs |
Who Is a Good Candidate for All-on-6?
- Missing most or all teeth in one or both arches
- Sufficient bone volume in both front and back of the jaw
- Strong bite force (bruxism, history of grinding)
- Wants to eliminate or minimise cantilever extension at the back
- Patients wanting the most stable possible full-arch solution
Patients with significant bone loss at the back of the jaw may need a sinus lift (upper) or bone augmentation before All-on-6 is possible. In those cases, All-on-4 with angled implants is often the more practical choice — no grafting required.
The All-on-6 Procedure: What to Expect
- Initial consultation and CBCT scan: 3D imaging to assess bone volume and plan implant positions precisely
- Extraction of remaining teeth: Done on the same day as implant placement in most cases
- Implant surgery: Six implants placed under local anaesthetic or IV sedation — takes 2–4 hours per arch
- Same-day provisional bridge: Temporary fixed teeth fitted before you leave the clinic
- Healing (3–6 months): Soft diet during osseointegration — the implants fuse with the bone
- Final bridge fitting: Permanent zirconia or acrylic-on-titanium bridge placed and adjusted
All-on-6 Bridge Materials: Acrylic vs Zirconia
| Material | Cost Premium | Lifespan | Aesthetics | Repairability |
|---|---|---|---|---|
| Acrylic on titanium frame | Lower | 7–12 years | Good | Easier — individual teeth can be replaced |
| Zirconia (monolithic) | Higher (£2,000–£4,000 more) | 15–25 years | Excellent | Harder to repair if chipped |
| Zirconia fused to titanium | Mid-range | 15–20 years | Excellent | Good |
Zirconia is the premium choice for long-term durability and aesthetics. Acrylic is a solid option for patients prioritising upfront cost, or as a longer-term provisional while assessing the final result.
Frequently Asked Questions
How much does All-on-6 cost in the UK?
All-on-6 in the UK costs £10,000–£22,000 per arch depending on the clinic, implant brand and bridge material. Full-mouth treatment (both arches) typically ranges from £20,000 to £40,000.
Is All-on-6 better than All-on-4?
Not universally — it depends on your anatomy. All-on-6 distributes load over more implants and reduces cantilever, which benefits patients with good bone volume and strong bite force. All-on-4 uses angled implants to avoid bone grafts when posterior bone is limited. Your surgeon should recommend the approach suited to your specific anatomy.
Can you eat normally with All-on-6?
Yes — after the healing period (3–6 months) most patients can eat a normal diet including hard foods. During healing, a soft diet is required to protect the integrating implants.
How long does All-on-6 last?
The implant posts can last a lifetime with good oral hygiene and regular maintenance. The bridge typically lasts 10–15 years for acrylic or 15–25 years for zirconia before needing replacement.
Is All-on-6 available on the NHS?
No. All-on-6 treatment is not available on the NHS. It is a private treatment. NHS full dentures remain the NHS alternative for full arch tooth loss.
