All-on-4 vs All-on-6: Which Full-Arch Implant Is Right for You?
All-on-4 or All-on-6? A clear, honest comparison of implants used, cost, bone needs and who each option suits.
Both All-on-4 and All-on-6 replace a full arch with a fixed bridge on just a handful of implants — the difference is four implants versus six, and how much bone and bite force each is built to handle. All-on-4 typically costs £3,000–4,500 per arch in Turkey; All-on-6 is usually a bit higher because it uses more implants. Your CT scan, not a general preference, decides which one actually fits your jaw.
Key takeaways
- All-on-4 uses four implants; All-on-6 uses six — both support one fixed full-arch bridge.
- All-on-6 spreads the bite over more implants, which can suit more bone or a heavier bite.
- All-on-4 in Turkey typically costs £3,000–4,500 per arch; All-on-6 is usually somewhat higher.
- The right choice depends on your bone volume and bite, confirmed by a CT scan — not a fixed rule.
What's the actual difference between All-on-4 and All-on-6?
Both techniques replace a full arch of teeth with one fixed bridge supported by implants rather than natural roots — the number of implants is the core difference. All-on-4 places two implants vertically at the front and two angled at the back, using the angle to anchor into the strongest available bone even where volume is limited. All-on-6 adds two more implants, spreading the load across six anchor points instead of four. More implants generally means more support and a wider safety margin, but it also means more surgical sites and, in some cases, a requirement for more bone to begin with.
| Criterion | All-on-4 | All-on-6 |
|---|---|---|
| Implants per arch | 4 | 6 |
| Best suited to | Moderate bone loss | More available bone, heavier bite |
| Load distribution | Concentrated on 4 posts | Spread across 6 posts |
| Typical cost in Turkey | £3,000–4,500 per arch | Usually a little higher — ask for an exact quote |
| Same-day fixed temporaries | Usually possible | Usually possible |
Which costs more — All-on-4 or All-on-6?
All-on-4 in Turkey typically costs £3,000–4,500 per arch, using the same established pricing that applies across our full-arch treatments. All-on-6 uses two more implants and, often, more surgical time and lab work, so it's typically a bit higher — we don't quote a fixed figure here because the exact cost depends heavily on your individual case, any grafting needed, and the bridge material. Ask us on WhatsApp for a written, itemised quote once your CT scan and photos have been reviewed, so you're comparing your real number rather than a generic range.
Which one suits your bone and your case?
Neither option is objectively ‘better’ — each is matched to a different starting point. All-on-4 was originally developed for patients with reduced bone at the back of the jaw, using the angled posterior implants to avoid grafting in many cases. All-on-6 is often chosen when there's more bone available to work with, when a heavier bite or a history of teeth grinding calls for extra support, or when your surgeon wants a wider safety margin for a particular case. The only way to know which applies to you is a 3D CT scan reviewed by a named, accredited implant surgeon.
All-on-4 often fits when
- Bone volume is moderate, especially at the back of the jaw
- You want the most efficient full-arch surgery
- Your bite force is average
- You're replacing a full arch, not isolated teeth
All-on-6 often fits when
- You have more available bone to work with
- Your bite is heavier or you grind your teeth
- Extra long-term stability is a priority for you
- Your surgeon recommends spreading load over more implants
Does the healing timeline differ between the two?
Not meaningfully. Both All-on-4 and All-on-6 follow the same biological process — the implants need to fuse with the jawbone through osseointegration, which takes roughly 3–6 months regardless of whether there are four or six of them. Both techniques commonly allow a fixed temporary bridge on the day of surgery, so you're not left without teeth during that healing period. The final, custom porcelain or zirconia bridge is fitted afterwards on a second, shorter visit once your dentist confirms the implants have fully integrated.
Frequently asked
It generally spreads the bite over more implants, which can add a margin of support, but ‘stronger’ depends on your bone and bite, not the implant count alone. A well-planned All-on-4 can be entirely sufficient for many patients.
Yes — the plan is confirmed after your 3D scan, not before. If your bone or bite suggests six implants would serve you better, your surgeon will discuss that with you before surgery, not during it.
It depends on your bone volume, not the technique itself. Some All-on-6 cases need no grafting at all; others do. Your CT scan will show this clearly.
Not typically. The extra two implant sites add a little more surgical time, but most patients describe recovery for both techniques as similarly manageable with simple painkillers.
All-on-4 is the more frequently used starting point because it suits a wide range of bone situations, but All-on-6 is a well-established, equally valid option for the right case.
