All-on-4 vs All-on-6: cost and clinical differences
Written by Saurabh SharmaSources checked against the citations pageCost data last verified
Both are full-arch, fixed implant systems that replace an entire row of teeth with a bridge anchored on implants, so it's easy to see them as the same product with a different number attached. They're not quite. The implant count changes how the case is planned, what bone it can work with, and usually the price. Here's what's actually different, with sourcing.
What the implant count actually changes
All-on-4 was designed around a specific workaround: placing the back two implants at an angle lets a surgeon anchor a full arch using bone that's already there, in patients who'd otherwise need a bone graft first. That's the technique's whole selling point, fewer implants, often no graft, one surgery.
All-on-6 uses six implants instead of four to support the same style of fixed bridge. A biomechanical study cited across several implant-planning resources found that spreading the load across six implants produced lower stress on both the cortical bone and the implants themselves compared to four, which is the mechanical argument for going with more implants when the case calls for it. Six implants also means more redundancy: if one fails, the bridge has more remaining support than a four-implant arch would.
Neither is universally "better." All-on-6 is generally the recommendation when bone density is uneven across the arch, when bite forces are unusually heavy, when the jaw is wider or longer than average, or when a patient's medical history makes healing less predictable and a dentist wants more support built in from the start. Outside of those situations, four implants is often considered sufficient, and adding two more just adds surgical sites and cost without a clear clinical upside.
Cost comparison
| Option | Typical cost per arch |
|---|---|
| All-on-4, standard (acrylic hybrid) | $15,000 – $25,000 |
| All-on-4, premium (zirconia hybrid) | $25,000 – $38,000 |
| All-on-6 (regional data, Texas market) | $23,000 – $32,000 |
That All-on-6 figure comes from one regional cost breakdown (Central Texas, 2026), not a national average, so treat it as directional rather than exact for your area. It puts All-on-6 roughly $3,000 to $5,000 higher per arch than All-on-4 in that market, attributed to the extra implant hardware and added surgical and lab time. Worth being upfront about: broader national cost surveys generally don't break All-on-4 and All-on-6 out separately, they quote both inside the same overall per-arch range, since material choice tends to move the price more than two extra implants do. If a provider quotes you a number for either option, ask them to itemize implant count separately from material so you can see what's actually driving the price.

The calculator below is set to the full-arch category. It doesn't currently split All-on-4 from All-on-6 since national pricing data doesn't cleanly separate them, but it will give you a real starting range based on material choice and add-ons, which you can bring into a conversation with your provider once they've told you how many implants your specific case needs.

All-on-4 vs All-on-6 FAQ
What's the actual difference between All-on-4 and All-on-6?
The number in the name is the number of implants placed per arch to support a full fixed bridge, four versus six. All-on-4 relies on the back two implants being angled to make the most of available bone without a bone graft, which is the whole reason the technique exists. All-on-6 spreads the same bridge across two more implants, which can mean better load distribution and a backup if one implant fails, but it also means more surgical sites and, usually, a somewhat higher bill.
How much do All-on-4 dental implants cost?
A standard (acrylic hybrid) All-on-4 arch runs $15,000 – $25,000, and a premium zirconia hybrid arch runs $25,000 – $38,000. What's included in that figure is the implants themselves, the abutments, and the prosthetic arch. It generally does not include bone grafting, extractions, sedation, or imaging if your case needs them, those get billed separately and the calculator below itemizes them.
Does insurance cover All-on-4 or All-on-6 dental implants?
Most dental insurance, including Delta Dental plans, treats full-arch implant cases as a major or elective procedure rather than a covered basic service. Some plans will cover a portion after a waiting period, but the annual maximum on most dental plans is far below the cost of even one arch, so plan to cover the bulk of it out of pocket or through financing regardless of which implant count you go with. Checking your specific plan's implant clause is the only reliable way to know what you'd actually get reimbursed.
Who actually needs All-on-6 instead of All-on-4?
Cases with uneven bone loss across the arch, unusually heavy bite forces, a wider or longer jaw, or a patient history that makes healing less predictable are the situations where a prosthodontist is more likely to recommend six implants over four. If your bone density is reasonably even and you don't have one of those complicating factors, four is often considered sufficient, which is part of why All-on-4 became the more commonly marketed option in the first place. This is a clinical call that needs a CT scan and an in-person exam, not something to decide from a cost comparison alone.
Is All-on-6 always more expensive than All-on-4?
Usually somewhat, but published pricing doesn't cleanly separate the two the way it separates material choice. Regional pricing data out of Texas puts All-on-6 roughly $3,000 to $5,000 higher per arch than All-on-4, driven by the extra implant hardware and longer surgical and lab time. But broader national cost surveys often quote All-on-4 and All-on-6 inside the same overall per-arch range, since material (acrylic versus zirconia) and case complexity tend to move the price more than two extra implants do. Get a written breakdown from your provider showing implant count separately from material so you can see what you're actually paying for.
Does the calculator below give a separate price for All-on-6?
Not yet. The calculator's "Full arch (All-on-4/6)" category runs one blended full-arch price range, because the underlying published cost data this site relies on generally doesn't separate the two implant counts cleanly at a national level, only at the regional or per-provider level. Use the estimate below as a starting range for either option, then ask your provider for a case-specific quote once they've determined how many implants your case actually needs.
