Your dentist mentioned All-on-4. The clinic in Turkey is suggesting All-on-6. You're not sure what the difference is, which one you need, or whether the more expensive option is actually better for your situation.
The answer depends on your bone density, how many teeth you're missing, and what your jaw can support. Here's the honest comparison.
All-on-4 vs All-on-6 Dental Implants: A Complete Comparison
Four implants versus six implants. Both give you a full set of fixed teeth, but the engineering is different.
All-on-4 uses four dental implants to support a full arch of replacement teeth, while All-on-6 uses six implants for the same job. All-on-6 spreads bite force across more anchor points and works best when you have good bone density. All-on-4 was designed for people with less bone — it uses angled back implants to grab onto whatever bone you have left.
Your bone density matters most. But budget, jaw size, and whether you grind your teeth all play a role.
What Each Procedure Involves
All-on-4
Two straight implants go in the front. Two angled implants (usually 30-45 degrees) go in the back.
The angled placement is the clever bit. It reaches denser bone toward the front of your jaw, dodging the need for bone grafting in most cases. A full arch of 10-12 teeth attaches to these four implants, either the same day or after healing.
All-on-6
Six implants spread across your jaw: two front, two middle, two back. More anchor points mean more stability and stronger bite force.
The force from chewing gets distributed across six points instead of four. Less stress on each implant. Same full arch attached, but with better support underneath.
Side-by-Side Comparison
| Factor | All-on-4 | All-on-6 |
|---|---|---|
| Number of implants per arch | 4 | 6 |
| Bone density required | Lower (angled implants compensate) | Higher (vertical placement standard) |
| Bone grafting typically needed | Rarely | Sometimes |
| Procedure time | 2-3 hours per arch | 3-4 hours per arch |
| Bite force distribution | Concentrated on 4 points | Spread across 6 points |
| Long-term durability | Excellent (15-25 years) | Excellent (20-30 years) |
| Suitability for full arch | Yes | Yes |
| Immediate loading possible | Yes (same-day teeth) | Yes (same-day teeth) |
| Recovery time | 3-6 months full integration | 3-6 months full integration |
| Implant failure impact | Loss of 1 implant is more critical | Greater redundancy if 1 implant fails |
Cost Comparison
The price difference reflects the extra implants and longer surgery time.
Per-Arch Pricing
| Treatment | UK Private Price | Turkey Price | Savings |
|---|---|---|---|
| All-on-4 (standard implants) | £12,000 - £15,000 | £4,000 - £5,500 | 60-67% |

| All-on-6 (premium implants) | £18,000 - £25,000 | £7,000 - £10,000 | 60-65% |
Full Mouth (Both Arches)
| Treatment | UK Private Price | Turkey Price | Savings |
|---|---|---|---|
| All-on-4 both arches (standard) | £22,000 - £28,000 | £7,500 - £10,000 | 64-66% |
| All-on-6 both arches (standard) | £28,000 - £34,000 | £9,500 - £13,000 | 62-66% |
These prices include implants, prosthetic arch, consultation, imaging, and standard aftercare. Bone grafting costs extra if you need it.

When All-on-4 Works Better
You have bone loss. All-on-4 was invented for this exact problem. If traditional implants won't work because you don't have enough bone, All-on-4 might still be possible without grafting.
You want to skip bone grafting. Bone grafts add 3-6 months and significant cost. All-on-4's angled technique usually avoids this.
Budget matters. Two fewer implants = lower cost. For both arches, the savings add up.
Speed matters. Fewer implants mean shorter surgery and easier same-day teeth placement.
When All-on-6 Works Better
Your bone density is good. If bone loss isn't your main problem, six implants give better force distribution without needing the angled approach.
You grind your teeth. Bruxism puts serious stress on implants. Six anchor points handle this better than four.
You want maximum durability. If one implant fails (rare but possible), you still have five supporting the prosthetic while a replacement gets placed.
You have a larger jaw. Bigger jaw structures benefit from wider implant distribution across the full arch span.
You eat challenging foods. Steaks, nuts, crusty bread — the extra bite force capacity of All-on-6 handles demanding diets better.
Recovery Comparison
| Recovery Stage | All-on-4 | All-on-6 |
|---|---|---|
| Immediate post-surgery swelling | Moderate (2-3 days) | Moderate to significant (3-5 days) |
| Soft food diet | 2-4 weeks | 2-4 weeks |
| Return to normal activities | 3-5 days | 5-7 days |
| Temporary prosthetic worn | 3-6 months | 3-6 months |
| Final prosthetic fitted | 4-6 months post-surgery | 4-6 months post-surgery |
| Full osseointegration | 3-6 months | 3-6 months |
All-on-6 involves more surgical work, so expect slightly more swelling initially. By two weeks, comfort levels are similar for both procedures.
Getting Your Assessment
Your bone density, jaw structure, and bite habits determine which option suits you. An online dental assessment narrows this down before you travel.
A MyDentalFly assessment covers:
- Which teeth need extraction or are already missing
- History of bone loss or gum disease
- Eating habits and lifestyle factors
- Previous dental work and complications
Clinics use this information for preliminary recommendations and accurate quotes for both options. The final decision usually requires a 3D CBCT scan at the clinic, but the assessment gets you 90% of the way there.
Which One Do You Need?
The candidacy checker tells you in 60 seconds whether bone loss, smoking, or medical conditions affect your suitability for implants. The free dental health check then maps your teeth and recommends whether All-on-4 or All-on-6 is the right call for your specific jaw.
The implant brand comparison shows success rates across 13 brands — because the brand matters as much as the technique. We've verified every clinic on our platform and your dental tourism consultant coordinates everything.

Key Takeaway
Before you book anything, get a dental health check. Knowing exactly what treatment you need — and what it should cost — protects you from surprise bills, unnecessary procedures, and clinics that don't match your needs.
Know what you may need before you fly
The most common concerns we hear from patients:
- •“The price changed when I arrived — they said I needed extra work”
- •“I didn't know which clinic was right for my situation”
- •“I had no way to compare — every clinic quoted different things”
We built MyDentalFly to solve these problems. Not by replacing clinics, but by making sure you understand what you may need before any clinic gets involved.
Our interactive dental health check lets you map your teeth, answer a few health questions, and get a free report showing what treatment you may need and what it could cost. It's interactive, easy to understand, and designed for people without a dental background.
From there, we match you with clinics based on your actual dental situation — not every clinic suits every case. Some cases need experienced surgeons, some need specific equipment. You compare real treatment plans side by side and decide when you're ready.

Why use a platform for dental treatment abroad?
Think of us like Booking.com for dental tourism — except we assess you first.
Getting dental work abroad means navigating a different healthcare system, a different language, and clinics you've never visited — all while trying to understand what treatment you actually need. Most people do this alone, piecing together information from WhatsApp messages and online reviews.
MyDentalFly organises the entire process. Your dental needs are assessed before you travel, you compare treatment plans from vetted clinics side by side, and everything — from your initial assessment to your aftercare notes — is documented on your patient portal. We're not a clinic and we don't sell treatment. We're the layer between you and the clinic that keeps everything transparent and on track.
