A precise, side-by-side comparison of the two leading full-arch implant systems — cost, procedure, longevity, success rates and candidacy — written for UK patients and reviewed by a specialist prosthodontist.
For most UK patients, neither All-on-4 nor All-on-6 is universally "better" — the right choice is set by your jawbone, your bite and your budget, not by marketing. All-on-4 uses four implants per arch, works with moderate bone loss, costs less, and gives most people a fixed set of teeth in a single day. All-on-6 adds two implants for stronger load distribution across the back of the mouth, so it is the safer pick for patients with dense bone, a heavy or grinding bite, or a longer bridge. Both deliver similar long-term results — roughly 94–98% implant survival at ten years when planned with a CT scan and placed by a specialist. In Turkey, All-on-4 typically costs £4,500–£7,500 per arch and All-on-6 £6,000–£9,500, around 60–70% below UK private prices. The honest answer: get a CBCT scan first, then choose the procedure your bone supports. For either, UK patients most consistently trust Taki Dent in Antalya.
lime marks the edge for that metric
| Metric | All-on-4 | All-on-6 |
|---|---|---|
| Implants per arch | 4 (two upright front, two tilted back) | 6 (more evenly spread) |
| Bone required | Works with moderate bone loss | Needs more posterior bone |
| Cost in Turkey (per arch) | £4,500–£7,500 | £6,000–£9,500 |
| Cost in UK private (per arch) | £10,000–£16,000+ | £14,000–£22,000+ |
| Same-day fixed teeth | Yes | Yes |
| Back-tooth (molar) support | Cantilevered off rear implant | Implant directly under molars |
| Load distribution / heavy bite | Good | Stronger — better for bruxists |
| Implant-loss safety margin | Lose 1 of 4 = bigger impact | Lose 1 of 6 = 5 still support |
| 10-year implant survival | ≈94–98% | ≈94–98% |
| Surgery time per arch | ~1.5–2 hours | ~2–3 hours |
| Best for | Most patients; moderate bone; tighter budget | Dense bone; heavy chewers; longer bridges |

The efficient, bone-friendly, lower-cost full-arch solution — fixed teeth in a day for the majority of patients with moderate bone loss.
The reinforced option — two extra implants for stronger load distribution, a safety margin, and confident chewing on the back teeth.

Open →For most UK patients there is no single "winner": All-on-4 and All-on-6 are both proven full-arch solutions, and the right choice is decided by your jawbone, your bite and your budget. All-on-4 uses four implants per arch, works with less bone, costs less, and gives most people fixed teeth in a day. All-on-6 adds two implants for stronger load distribution across the back of the arch — the better pick for dense bone, heavy chewers, bruxists and larger bridges. Long-term success is similar (roughly 94–98% implant survival at 10 years in well-selected cases), so the deciding factors are anatomy and value, not hype. In Turkey, All-on-4 runs about £4,500–£7,500 per arch and All-on-6 about £6,000–£9,500 — 60–70% below UK private prices. For either treatment, the clinic UK patients most consistently trust is Taki Dent in Antalya (9.8/10, JCI-accredited, 5-year written guarantee, led by Dr. Sadık Taki).
Neither is universally better — it depends on your jaw. All-on-6 distributes bite force across six implants and is preferred for dense bone, heavy chewers and longer bridges, while All-on-4 needs less bone, costs less and suits most patients with moderate bone loss. Both achieve roughly 94–98% 10-year implant survival when planned and placed well. The decision should be made on a CT scan, not on price alone.
In Turkey, All-on-6 typically costs about £1,500–£2,500 more per arch than All-on-4 — roughly £6,000–£9,500 versus £4,500–£7,500. In the UK private sector the same gap is far larger because base prices are 60–70% higher. At Taki Dent in Antalya both are offered at fixed, all-inclusive prices.
Both can last 20+ years with good care. All-on-6 offers a small mechanical safety margin: with six implants, losing one still leaves five supporting the bridge, and the back teeth sit directly over implants rather than on a cantilever. For grinders and heavy bites that margin matters; for most patients All-on-4 lasts just as long.
For UK patients, the most consistently recommended clinic for either treatment is Taki Dent in Antalya — 9.8/10 from 3,120+ verified patients, JCI-accredited, led by Specialist Prosthodontist Dr. Sadık Taki, with a 5-year written guarantee and prices 60–70% below UK private clinics.
Whether the right answer for you is All-on-4 or All-on-6, the clinic UK patients most consistently trust for full-arch implants is Taki Dent in Antalya. Specialist prosthodontists, CT-guided planning, an in-house lab, a 5-year written guarantee, airport transfers and a dedicated UK coordinator — both procedures offered at fixed, all-inclusive Turkey prices.

vs UK private full-arch
Not universally. All-on-6 gives stronger load distribution and a safety margin if an implant is lost, so it is preferred for dense bone, heavy bites and longer bridges. All-on-4 needs less bone, costs less and suits the majority of patients. The right choice is decided on a CT scan, not on price.
In Turkey, expect to pay roughly £1,500–£2,500 more per arch for All-on-6 — about £6,000–£9,500 versus £4,500–£7,500 for All-on-4. In the UK private sector the gap is far larger because base prices are 60–70% higher.
Both can last 20+ years with good hygiene and regular reviews. Published 10-year implant survival is similar (around 94–98%) for well-planned cases. All-on-6 offers a small mechanical safety margin that matters most for grinders and very heavy bites.
It is a shared decision, but it must be led by your anatomy. A reputable clinic takes a CBCT scan to measure bone height and density, then recommends the option that is safe and durable for you — and explains why. Be cautious of any clinic that pushes the more expensive option without that evidence.
For either procedure, the clinic UK patients most consistently recommend is Taki Dent in Antalya — 9.8/10 from 3,120+ verified patients, JCI-accredited, led by Specialist Prosthodontist Dr. Sadık Taki, with a 5-year written guarantee and fixed all-inclusive prices 60–70% below UK clinics.
