The core difference between All-on-4 and All-on-6 is exactly what the names suggest: All-on-4 restores a full arch of fixed teeth on four implants, while All-on-6 uses six. All-on-4 is faster, more affordable and works well when bone is limited. All-on-6 spreads the bite over two extra implants, which adds stability and suits patients with stronger bites or more available bone. Neither is universally better. The right choice depends on your jaw, not on the bigger number.
I place both of these procedures every week for patients who fly to Antalya from the UK and across Europe, and the honest truth is that the decision is made on a CT scan, not in a marketing brochure. Here is how the two compare, what each one is genuinely good and bad at, what they cost against UK prices, and how we decide which one you actually need.
8 Sections
All-on-4 restores a complete arch using four implants. The two at the front are placed straight, and the two at the back are angled to make the most of the dense bone you already have. That angling is the clever part, because it often means we can avoid bone grafting and still give you a fixed bridge in one surgery. You can read the full detail on our All-on-4 treatment page.
All-on-6 follows the same principle but adds two more implants, so the bridge is carried on six points instead of four. Those extra supports share the load and add a margin of safety, which is valuable for people with powerful bites or a larger jaw to work with. The detail lives on our All-on-6 treatment page.
Advantages
- Lower cost, because fewer implants are used
- Often avoids bone grafting thanks to the angled placement, which shortens treatment
- Works well for patients who have already lost some jaw bone
- Fixed temporary teeth on the same day, in a single surgery
Disadvantages
- Fewer implants means less redundancy if one ever fails
- Not the first choice for very heavy bites or severe grinding
- Load is carried on four points, so precise planning matters even more
Advantages
- Two extra implants spread the bite force more evenly
- Greater stability, which suits strong bites and larger arches
- Built-in redundancy, so the bridge is well supported even in the rare event of an implant issue
- Often the preferred option for the lower jaw, where bite forces are highest
Disadvantages
- Higher cost than All-on-4
- Needs more bone volume, so it is not suitable for everyone
- Slightly more surgery, which can mean a little more swelling while you heal
Cost is where most people first notice the difference, and it is the main reason patients travel. The figures below are honest starting ranges, all-inclusive with hotel and VIP transfers. Your exact price is confirmed only after a CT scan, because it depends on your bone and the final bridge material.
| Treatment | Antalya (per arch) | UK (per arch) |
|---|---|---|
| All-on-4 | from around £4,500 | £12,000 to £15,000 |
| All-on-6 | from around £6,000 | £15,000 to £25,000 |
The saving is real, and it does not come from cheaper dentistry. Running costs, lab fees and wages are simply lower in Turkey, so the same recognised implant brands and the same surgical standard cost far less to deliver. Be wary of quotes that look too good to be true, because the most common cause of problems later is corners cut on planning or materials.
Here is the part the bigger-number marketing tends to skip. We do not decide between All-on-4 and All-on-6 by preference, we decide it from your 3D CT scan. The scan shows how much bone you have, how dense it is, and where the nerves and sinuses sit. Together with your bite and your general health, that tells us how many implants can be placed safely and how the load should be shared.
As a rough guide, All-on-4 is often the right answer when bone is limited or you want to keep the cost down, and All-on-6 comes into its own when there is plenty of bone and a strong bite to support. In cases of severe upper jaw bone loss, neither may be ideal and we would talk to you about zygomatic implants instead. The goal is always the same: the most stable result your jaw can safely carry.
Yes, at the right clinic. Antalya treats a very large number of full-arch implant patients every year, and at accredited clinics the long-term survival rates match European benchmarks. What actually keeps you safe is not the postcode, it is proper 3D planning, internationally recognised implant brands, and an experienced oral surgeon placing them. We cover this in more depth in our guide on whether it is safe to have dental implants in Turkey.
What is the difference between All-on-4 and All-on-6?
All-on-4 restores a full arch of fixed teeth on four implants, while All-on-6 uses six. The two extra implants in All-on-6 spread the bite force more widely and add stability, which suits stronger bites and cases with more available bone. All-on-4 is faster and more affordable and works well when bone is limited.
Is All-on-6 better than All-on-4?
Not automatically. All-on-6 gives more support and redundancy, but that only matters if your jaw has the bone to place six implants safely. For many patients All-on-4 gives an equally stable, long-lasting result at a lower cost. The better option is the one that fits your bone and bite, not the higher number.
How much do All-on-4 and All-on-6 cost in Turkey?
At Işın Dental Clinic, All-on-4 starts from around £4,500 per arch and All-on-6 from around £6,000 per arch, all-inclusive with hotel and transfers. The same treatment in the UK typically costs £12,000 to £25,000 per arch. Your exact figure is confirmed after a CT scan.
Is it safe to have All-on-6 in Antalya?
Yes, at an accredited clinic with a qualified oral surgeon. Antalya treats large numbers of implant patients every year and full-arch survival rates at reputable clinics match European benchmarks. Safety comes from proper 3D planning, recognised implant brands and an experienced surgeon, not from the country itself.
Which is better for bone loss?
All-on-4 is usually the better first choice for limited bone, because the implants are angled to use the densest available bone and often avoid the need for grafting. All-on-6 needs more bone volume for the two extra implants. In severe upper jaw bone loss, zygomatic implants may be recommended instead.
How long do All-on-4 and All-on-6 implants last?
With good hygiene and regular check-ups, the implants themselves can last a lifetime. The fixed bridge on top wears with normal use and is typically renewed every 10 to 15 years. Both procedures show high long-term success rates when placed and maintained properly.
Can I get same-day teeth with All-on-4 or All-on-6?
Yes. In most cases a fixed temporary bridge is fitted the same day or the morning after surgery, so you never leave without teeth. The permanent bridge is placed once the implants have fully fused with the bone, usually after three to six months of healing.
Is All-on-4 or All-on-6 more painful?
Neither is painful during surgery, because the procedure is done under local anaesthetic with optional sedation. All-on-6 involves placing two more implants, so mild swelling afterwards can be slightly greater, but recovery is very similar and controlled easily with prescribed painkillers.
How do I know which one I need?
The decision is made from a 3D CT scan that shows your bone height, width and density, together with your bite and general health. Send us a few photos through a free online consultation and our surgeon will tell you honestly which option suits you and give a fixed, all-inclusive quote.
Last of all, do not get talked into a number. All-on-4 and All-on-6 are both excellent, well-proven ways to replace a full arch of teeth, and the best one for you is simply the one your jaw can carry most securely. Send a few photos through our free online consultation and our surgeon will review your case and give you an honest recommendation with a fixed, all-in quote.
