All-on-6 Dental Implants: What They Are and What They Cost vs All-on-4
All-on-6 replaces a full arch of teeth on six implants — typically $24,000-$38,000 per arch in 2026, versus $20,000-$30,000 for All-on-4. The two extra implants cost roughly $1,500-$4,000 each and buy redundancy plus stronger back-tooth chewing; All-on-4 counters with angled implants that usually avoid bone grafting.
New to the terms? The All-on-6 glossary entry covers candidacy, procedure steps and recovery in depth; this page does the money: what each protocol costs, component by component, and whether the 5th and 6th implant earn their price.
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.

Cross-check: the few clinics that publish an All-on-6 number land inside this band — two 2026 provider pages we reviewed both quote $24,000-$31,000 per arch, and most competitors publish no figure at all.
What the 5th and 6th implant actually cost — and buy
Nobody on the current search results prices the marginal implant, so here is the math from the component rows above. The all-in gap between protocols is $3,000-$8,000 for two extra implants — roughly $1,500-$4,000 per additional implant, before any graft those posterior positions may force. What each marginal dollar buys:
| The extra $1,500-$4,000 per implant buys | The hidden multiplier it can trigger |
|---|---|
| Redundancy: lose one implant years later and five still carry the bridge | Posterior placement raises the odds of a $2,000-$4,000 sinus lift or graft |
| Direct implant support under the molars (no cantilever) | Extra months of healing if grafting is needed |
| Load spread across six posts — less stress per implant for grinders | Two more posts to keep clean for life |
The honest framing: for a heavy chewer with good posterior bone, the marginal implant is cheap insurance. For a patient with a low sinus and light bite, the same implant can cascade into grafting costs and delays that erase its value — which is why the two protocols coexist rather than one having "won."
Where your state sits (All-on-4 series)
Full-arch pricing tracks local restorative costs. In our state dataset, the All-on-4 per-arch state average runs from about $12,595 (Alabama) to $19,275 (California), median about $14,870 — an estimated series scaled by each state's Restorative Cost Index, and a base-package figure: advertised all-in zirconia packages typically land in the $20,000-$30,000 band above it. All-on-6 follows the same geography plus its $3,000-$8,000 premium. State-by-state detail lives on the All-on-4 cost hub, or check yours directly:

Estimated series (Restorative Cost Index) and a base-package figure — advertised all-in zirconia packages typically run higher; add the $3,000-$8,000 premium for All-on-6. Series basis: estimated series scale the national range by the state’s Restorative Cost Index; bands around averages are modeled, not measured percentiles. Insurance model: preventive 100% / basic 75% / major 50% / cosmetic and implants often excluded, payout capped at your annual maximum — real plans vary.

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.
