All-on-4 vs All-on-6 vs All-on-X: How to Choose — and What Each Costs in China (2026)

If you are weighing All-on-4 against All-on-6 — or wondering what "All-on-X" on a clinic's price list means — the short answer is this: they are variations of the same idea, a full arch of fixed teeth anchored on dental implants, and the right variant is decided by your jawbone, not by which name sounds more premium. All-on-6 is not automatically stronger, and All-on-4 is not automatically a compromise. This guide explains how the three approaches differ, who each one suits, the honest downsides, and what each costs in China in 2026 — where full-arch pricing runs roughly 50–70% less than comparable private treatment in the US, UK or Australia. For the broader picture of implant treatment in China, see our dental implants in China overview and the All-on-4 in China guide. (Still weighing a removable denture against implants altogether? That is a different decision we compare here.)

What do All-on-4, All-on-6 and All-on-X actually mean?

In one line: All-on-4 fixes a full arch of replacement teeth on four implants, All-on-6 does it on six, and All-on-X leaves the number to your surgeon and your CT scan — including zygomatic implants for severe bone loss. Here is what each means in practice.

All-on-4 means a full arch of fixed replacement teeth supported by four implants: two placed vertically at the front, two tilted at up to about 45° at the back. The tilt is the clever part — it lets the implants use the denser bone at the front of the jaw and often avoids bone grafting, which is why All-on-4 became the standard full-arch protocol worldwide.

All-on-6 dental implants use the same concept with six implants per arch. The extra two implants spread chewing forces more widely, which can suit larger jaws, heavier bites, or patients who want more redundancy — but they also require more bone volume in more places.

All-on-X dental implants are the newer umbrella category you increasingly see on price lists. It simply means "full arch on however many implants your anatomy needs" — four, five, six or more — decided from your CT scan rather than fixed in advance. In practice it also covers special cases such as zygomatic implants, extra-long implants anchored in the cheekbone for patients whose upper jaw has lost too much bone for standard placement. A related concept you may see in the US is 3-on-6: three separate bridge segments on six implants, which allows one segment to be repaired without removing the whole arch.

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

Not universally. All-on-6 adds support and load distribution where the bone allows it — but it means more surgery, a higher price, and more bone volume, the very thing many full-arch patients lack, and published long-term survival rates for both protocols are high and broadly similar. Any clinic that declares a winner before seeing your CT scan is selling, not planning. Some dentists do prefer six implants for long-term maintainability when conditions are good; large published reviews put 5–10-year implant survival at roughly 95–99% when treatment is properly planned and maintained (sources in our 2026 cost report).

The practical cons of All-on-6: it costs roughly $1,900–$4,700 more per arch in China (and far more in Western private clinics), it is not an option if your posterior bone is thin without grafting, and two extra implants are two extra sites to keep clean for life. The practical cons of All-on-4: less redundancy if one implant ever fails, and heavier bites may argue for more support. Your surgeon weighs exactly this trade-off on your scan.

What's "better" than All-on-4? All-on-X, 3-on-6 and zygomatic options

Nothing on the menu is categorically better — the newest thinking, reflected in the All-on-X naming, is that the implant count should follow the anatomy. If you have been told you "don't have enough bone for implants", that is usually the start of the conversation rather than the end of it: graftless tilted placement (the original All-on-4 idea), additional implants where bone permits, or zygomatic implants for severely resorbed upper jaws each solve a different version of that problem. Zygomatic cases are genuine specialist surgery and are quoted case-by-case after a CT review — be wary of any fixed online price for them.

All-on-4 vs All-on-6 vs All-on-X at a glance

Prices from the SinoCareLink network's published 2026 China dental implant cost report; per arch, including implants, framework, bridge and clinical fees. Extractions, bone grafting or a sinus lift (assessed on CBCT) and any pre-existing gum treatment are quoted separately if needed; flights and accommodation are not included. Your written quote follows a CT review.

What does each option cost in China — and is China good for implant work?

How much do dental implants cost in China?

A single implant runs from $799 all-inclusive with a Korean Dentium system, with Swiss Straumann systems from $1,699 to $2,599. Full-arch: All-on-4 from $5,599 and All-on-6 from $7,499 per arch with Dentium, rising to $13,999/$18,699 with Straumann Roxolid — against the $25,000–$50,000+ per arch common in US private care, with the same global implant systems used in the US and Europe. Extractions, grafting and sedation, where needed, are itemised separately in your written quote after a CT review.

Is China good for dental implants? For international patients the honest answer is yes, with the usual caveat that you choose the provider carefully. Treatment through the SinoCareLink network takes place in large established dental hospitals and clinics with high-volume implant programmes, digital planning workflows, genuine registered implant systems, and an insurer-backed warranty programme on implant work. English coordination — from records review to appointments and follow-up — is arranged end to end (see also: is medical tourism in China safe?), with treatment bases including Beijing, Shanghai and other major cities.

Insurance, affordability and treating abroad

Will insurance pay for All-on-4? Rarely in full. In the US, dental insurance annual maximums (commonly $1,000–$2,000) are a rounding error against a $25,000–$50,000 arch; some plans contribute to parts of treatment, and medical insurance almost never covers it. That gap is why full-arch treatment has become one of the most travelled-for procedures in dentistry. American patients most often look at Mexico first, and UK patients at Turkey — both can be far cheaper than home (our All-on-4 in Turkey cost & safety guide covers that route in detail). China's case in that comparison is hospital-grade providers at genuinely low prices, the same global implant brands, written itemised quotes, and warranty support in writing. Whichever country you consider, ask for those same four things in writing before paying a deposit.

Wondering where All-on-4 is cheapest overall? The short version: several countries, China among them, deliver full-arch treatment at a fraction of US/UK prices, and the right choice depends on more than the sticker price — our country-by-country implant cost comparison breaks it down.

The honest downsides — read this before you book anywhere

Full-arch implant treatment is real surgery with a real adaptation period, whichever number of implants you choose. Expect swelling and a soft-food phase in the early weeks; speech and bite take time to feel natural. A fixed bridge needs disciplined hygiene — food can trap beneath it, and a water flosser plus professional cleanings are part of the deal for life. Most full-arch bridges include a gum-coloured base, which most patients accept quickly but is worth seeing in photos beforehand. Not everyone is a candidate: uncontrolled diabetes, heavy smoking and certain medications raise failure risk, and very severe upper-jaw bone loss points to zygomatic or staged solutions rather than a standard protocol. And as with any implant surgery, infection, nerve irritation, sinus complications in the upper jaw and the occasional failure of an individual implant are possible — your surgeon should walk you through these risks before you consent. If you treat abroad — in China or anywhere else — also ask in advance how warranty work is handled once you are home. The implants themselves have high published survival rates, but the bridge is a wear part — expect maintenance, relines or replacement over a 10–15+ year horizon. For suitable candidates none of this need be a reason not to treat; it is the context an honest provider should volunteer before taking your deposit.

Frequently asked questions

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

Not universally. All-on-6 spreads load over six implants and adds redundancy where bone volume allows, but it costs more, involves more surgery, and requires bone that many full-arch patients don't have. Published survival rates for both protocols are high and broadly similar; the right choice comes from your CT scan and surgeon's assessment, not the name.

How much does a full mouth of dental implants cost?

In China, a full mouth on All-on-4 — both arches — runs from about $11,200 all-inclusive with Korean Dentium systems, or from about $18,600 with Swiss Straumann; single arches from $5,599. In the US, $25,000–$50,000+ per arch is common, so $50,000–$100,000+ for a full mouth in private care.

Do All-on-4 or All-on-6 teeth have fake gums, and do they feel real?

Most full-arch bridges include a gum-coloured base to restore lost gum and bone height — how visible it is depends on your lip line, and your provider should show you real examples first. Most patients find modern zirconia bridges feel close to natural teeth for chewing and speech after an adaptation period of a few weeks; food can collect under any fixed bridge, so a water flosser becomes part of your routine.

How long do All-on-4 or All-on-6 implants last?

Large published reviews put 5–10-year implant survival at roughly 95–99% with proper planning and maintenance, and many continue to function well in longer-term follow-up studies. The fixed bridge itself is a wear part: expect professional maintenance and possible relines or replacement over a 10–15+ year horizon, whichever protocol you choose.

Who is not a candidate for All-on-4?

Uncontrolled diabetes or gum disease, heavy smoking, certain medications (such as some osteoporosis drugs) and very severe upper-jaw bone loss can rule out a standard protocol. Many of those patients still have options — grafting, additional implants or zygomatic placement — which is exactly what a CT-based remote review clarifies before you commit to anything.

Will insurance pay for All-on-4?

Rarely in full. Typical US dental plans cap annual benefits at $1,000–$2,000 against a $25,000–$50,000 per-arch price, and medical cover almost never applies. Some patients offset parts of treatment; many simply treat abroad, where an all-inclusive written quote can come in below their insurance deductible logic altogether.

Is China good for dental implants?

Yes for well-chosen providers: large established dental hospitals with high-volume implant programmes, genuine Dentium and Straumann systems, digital planning, insurer-backed warranty support and English coordination through SinoCareLink. All-on-4 runs from $5,599 per arch all-inclusive in 2026 — roughly 50–70% less than comparable private treatment in the US, UK or Australia.
