A full-arch All-on-4 costs about $20,000-$30,000 per arch in 2026, while All-on-6 runs $24,000-$38,000 per arch — roughly $3,000-$8,000 more. All-on-4 usually avoids bone grafting with angled implants; All-on-6 adds a redundancy safety net and better back-tooth bite force.

Estimate your full-arch cost

The biggest variables are how many implants you place, whether you need a graft, and the prosthesis material. Use the calculator for a personalised per-arch range, then compare it to the independent benchmarks below.

All-on-4 vs All-on-6 cost by component (2026 benchmarks)

The headline difference is two extra implants and a higher chance of grafting. The zirconia prosthesis costs the same either way. The ranges below reconcile published 2024-2026 payer and provider fee data and separate the surgical fee from the prosthesis and any graft.

The redundancy safety net: why six can be safer than four

This is the factor clinics rarely lead with. Implants can fail years later from infection or peri-implantitis.

All-on-6 advantage — if one implant fails a decade in, five still support the bridge, and the restoration usually survives.
All-on-4 risk — lose one implant and the biomechanical balance is destroyed; the bridge often becomes unstable and may need to be completely redone.

Think of it as a plane with six engines versus a table with four legs: lose one engine and you keep flying, lose one leg and it wobbles.

Bone density and the "no-graft" appeal

In the back of the upper jaw the sinus often dips low, leaving little bone.

All-on-4 strategy — the surgeon tilts the back two implants 30-45 degrees to anchor in denser front-jaw bone and bypass the sinus, so most patients need no graft.
All-on-6 strategy — placing implants further back (under the molars) often requires a sinus lift or bone graft, adding $2,000-$4,000 and several months of healing.

Bite force and the cantilever

In All-on-4 the implants cluster toward the front, leaving the molars on a cantilever — an overhang with no implant directly beneath. All-on-6 places implants further back, so heavy chewing force transfers straight into an implant instead of stressing a floating section. Heavy chewers and grinders generally do better long-term on six.

Hygiene and maintenance

You must clean under a fixed bridge with a water flosser or superfloss every day.

All-on-4 — only four posts to navigate; the angled layout leaves slightly more space.
All-on-6 — six posts and tighter gaps require more dexterity. Poor hygiene drives peri-implantitis, the leading cause of late implant failure either way.

Which is right for you?

Choose All-on-4 if...	Choose All-on-6 if...
You have low bone volume in the back jaw	You have healthy, thick jawbone
You want to save $3,000-$8,000	You prioritise the redundancy safety net
You want teeth in a day without grafting	You will wait a few months for grafting if needed
You are older with lighter chewing forces	You are a heavy chewer or grinder

Hidden and adjunct costs people miss

These appear on most real full-arch plans and are the usual reason a quote climbs:

Item	Typical U.S. cost
Consultation & 3D CBCT scan	$300 – $950
Tooth extractions (per arch)	$600 – $2,000
Bone graft / sinus lift	$2,000 – $4,000
IV sedation	$500 – $1,500+
Final zirconia prosthesis upgrade (if not bundled)	$4,000 – $6,000

Insurance, HSA/FSA and financing

Related procedures — extractions, grafts and the prosthesis are often covered around 50% up to your annual maximum, even when the implants are not.
Two calendar years — staging treatment across a year-end can tap two annual maximums.
HSA/FSA — full-arch implants are an IRS-eligible medical expense, lowering the real cost by your tax rate.
Financing — CareCredit, dedicated dental lenders and in-house plans spread $20,000-$38,000 totals over time.

Frequently asked questions

How much more does All-on-6 cost than All-on-4?

Per arch, All-on-4 typically runs $20,000-$30,000 and All-on-6 runs $24,000-$38,000, so All-on-6 is usually about $3,000-$8,000 more. The gap comes from two extra implants and abutments plus a higher chance of needing a bone graft or sinus lift to place the posterior implants.

Is All-on-6 actually safer than All-on-4?

It has a redundancy advantage. With six implants, losing one years later still leaves five supporting the bridge, so the restoration often survives. With four, losing one disrupts the whole biomechanical balance and the bridge frequently has to be redone. Both protocols still report 95%+ implant survival over 10 years.

Why does All-on-4 avoid bone grafting?

All-on-4 angles the two back implants 30-45 degrees to anchor in dense front-jaw bone and bypass the sinus, so most patients avoid a sinus lift. All-on-6 places implants further back where the sinus often dips low, so it more commonly needs a graft, adding $2,000-$4,000 and several months of healing.

Can I chew steak better with All-on-6?

Often yes. In All-on-4 the molars sit on a cantilever (an unsupported overhang), so heavy back-tooth biting stresses a floating section of bridge. All-on-6 places implants further back, so chewing force transfers directly into an implant. Heavy chewers and bruxers tend to do better long-term on six.

Is the zirconia bridge included in the price?

It should be, but always confirm. The final zirconia prosthesis is roughly $10,000-$12,000 of the total and is the same for All-on-4 or All-on-6. Some clinics advertise a low number that covers only the implants and a temporary acrylic bridge, then bill the final zirconia teeth separately months later.

Does insurance cover All-on-4 or All-on-6?

Most plans treat full-arch implants as elective and exclude the implants themselves, but many cover related steps — extractions, a bone graft, or the prosthesis portion — at roughly 50% up to your annual maximum. Splitting treatment across two calendar years can tap two maximums and reduce out-of-pocket cost.

Can I upgrade from All-on-4 to All-on-6 later?

Usually not without redoing the case. The implant angles and positions differ, so converting means removing the angled posts and starting over, which is traumatic and costly. Decide based on your bone volume and chewing habits up front rather than planning to add implants later.
