If you are replacing a full arch of teeth, you will hear two terms over and over: All-on-4 and All-on-6. They sound similar, but the right choice depends on your jawbone, your bite and your budget — not on which number is bigger. Here is how to tell which you actually need.

What they have in common

Both replace an entire upper or lower arch of teeth with a fixed bridge anchored on dental implants — no removable dentures. Both can often give you fixed temporary teeth the same day as surgery. The only real difference is how many implants support the bridge: four versus six.

All-on-4: four implants

• Uses four implants, with the two back implants angled to make the most of available bone.
• Often avoids the need for bone grafting, so it can suit patients with some bone loss.
• Lower cost and, frequently, a faster path to fixed teeth.
• Very well documented, with decades of strong success data.

All-on-6: six implants

• Adds two more implants for extra support and a more even spread of biting force.
• Can be the better choice for the upper jaw (softer bone) or for patients with a strong bite.
• May offer added security for very full arches or heavier chewing loads.
• Costs more and sometimes needs slightly more bone.

Which one is right for you?

There is no universally “better” option — it is case-by-case. As a general guide:

• Good bone, budget-conscious, lower jaw → All-on-4 is often ideal.
• Upper jaw, heavy bite, or wanting maximum support → All-on-6 may be worth the extra.
• The honest answer for your mouth comes only after a CBCT 3D scan shows your bone volume and density.

Indicative cost in India

Option	Per arch (indicative)	Both arches (indicative)

Frequently asked questions

Is All-on-6 better than All-on-4?

Not automatically. All-on-6 adds support and can suit the upper jaw or a heavy bite, but All-on-4 is excellent for most cases and costs less. The right choice depends on your bone and bite, confirmed by a CBCT scan.

Do All-on-4 and All-on-6 give same-day teeth?

Both can usually provide fixed temporary teeth the same day as surgery, with the permanent bridge fitted a few months later once healing is complete.

Which needs bone grafting?

All-on-4 is designed to avoid grafting by angling the rear implants, so it often suits some bone loss. All-on-6 may need slightly more bone. A 3D scan determines what is needed.

How much does All-on-4 vs All-on-6 cost in India?

Indicatively, All-on-4 is around £3,500–6,500 per arch and All-on-6 around £4,500–8,000 per arch, confirmed after assessment.

Which lasts longer, All-on-4 or All-on-6?

Both have strong long-term success when placed well and maintained. More implants can spread load, but good planning, hygiene and not smoking matter far more than the number alone.
