All-on-4 vs All-on-6: The Difference, the Cost, and Which One You Need

Prices on this page are MedMatch Global's own published figures, checked against our partner clinics' current written price lists on August 11, 2026. Comparison figures for the U.S. and Canada are published private-pay averages, sourced separately. This page is general information, not medical advice.

The actual difference in one paragraph

Both techniques replace an entire arch of teeth with one fixed bridge carried on implants, and in both cases you leave with teeth. The difference is how many posts carry the load. All-on-4 places four implants, the two at the back angled to catch denser bone and avoid the sinus. All-on-6 places six, which spreads chewing force across more anchor points and gives the bridge more redundancy if one implant ever fails.

More implants is not automatically better. Four well-placed implants in good bone outperform six placed badly. What decides it is bone volume and density on your CBCT scan, how much force your bite generates, and whether the arch is upper or lower — the upper jaw is softer and more often gets six.

The prices, side by side

For comparison, All-on-4 for one arch is commonly quoted at $24,000–$30,000 in the United States and CA$25,000–CA$35,000 in Canada, with both arches passing $45,000. That is the gap that makes full-arch cases worth the flights when a single implant is not.

How the choice is actually made

A clinic that quotes All-on-6 before seeing a scan is selling, not diagnosing. The sequence should be: you send a panoramic x-ray or CBCT, the surgeon reads bone height and density at the planned implant sites, and only then do you get a number. Expect the answer to depend on:

• Bone volume. Thin or resorbed bone may not offer six safe sites without grafting — in which case four angled implants can be the more conservative plan, not the cheaper one.
• Upper versus lower jaw. The lower jaw is denser and often does well on four. The upper is softer and more frequently gets six.
• Bite force. Heavy grinders and patients opposing a natural dentition load the bridge harder, which argues for more anchors.
• Whether you need a graft or sinus lift. That changes both the plan and the timeline.

If two clinics give you different answers, that is not necessarily a red flag — it is a genuine clinical judgement call. What matters is that each of them can explain the reasoning from your scan.

Is All-on-8 worth it?

Some clinics market All-on-8, and for a small number of patients with heavy bite forces and good bone it is a legitimate plan. For most people it is upselling. Eight implants in a jaw that only supports six well is worse dentistry, not better, and the marginal benefit over six is small in the published literature. If you are offered All-on-8 without a scan-based reason, ask what specifically about your bone makes the extra two necessary.

The timeline, either way

Full-arch treatment normally runs across two trips. The first places the implants and fits a temporary fixed bridge, so you fly home with teeth. Three to six months later the second trip fits the final bridge once the implants have integrated.

• Trip one — 6 to 7 days: consultation, CBCT, extractions if needed, implant placement, temporary bridge fitted before you leave.
• Healing — 3 to 6 months at home: osseointegration. No travel, and you are not toothless during it.
• Trip two — 5 to 7 days: impressions, try-in, final bridge fitted and adjusted, written aftercare plan.

Anyone promising a permanent full-arch restoration in a single week is describing the temporary bridge, not the final one.

Frequently asked questions

What is the difference between All-on-4 and All-on-6?+

All-on-4 carries a full arch of fixed teeth on four implants, with the rear two angled to catch denser bone. All-on-6 uses six, spreading the chewing load across more anchor points and coping better with softer bone. Both give you a fixed bridge; the choice is a clinical one made from your CBCT scan.

How much does All-on-6 cost in Turkey?+

From $7,030 all-in per jaw through MedMatch — $6,400 paid directly to the clinic, plus 6 hotel nights, VIP transfers, your host and the flat $300 coordination fee. Flights are extra.

Do I need All-on-4 or All-on-6?+

Your scan decides. Dense lower-jaw bone often does very well on four; a softer upper jaw, heavy bite forces, or a wish for more redundancy argue for six. Any clinic quoting one over the other before seeing a CBCT is guessing.

How much is full mouth dental implants in Turkey for both jaws?+

From $8,300 all-in for both jaws, with hotel included. That is a single figure for the whole mouth, not per arch.

Is All-on-8 worth the extra money?+

For most patients, no. Eight implants only help if your bone genuinely supports eight good sites and your bite force justifies them. Ask what specifically on your scan makes the extra two necessary — if the answer is generic, it is an upsell.

How long do All-on-4 implants last?+

Published follow-up studies report implant survival in the region of 95% or better at ten years when placed and maintained properly. The bridge on top is the part that wears — plan on replacing or refurbishing the prosthetic at some point, and keep up hygiene appointments at home.

Will I be without teeth between the two trips?+

No. A temporary fixed bridge is fitted during the first trip, before you fly home. The final bridge goes on during the second trip once the implants have integrated.
