All-on-X Fixed Arch
Permanently fixed to a small number of implants. Functions like a full set of fixed teeth — no removal, no adhesive, cared for like natural teeth with brushing and regular review.
A full arch, fixed or more securely held
When a denture stops feeling like a solution, there's another option.
Maybe your denture shifts when you eat, or you've quietly ruled out certain foods altogether. All-on-X uses a small number of implants to support a fixed, full-arch replacement — and if a removable option still suits you better, an implant-supported overdenture can add real stability without going fully fixed. We'll talk through both honestly before anything is decided.
A denture that works, and a denture that lives with you, aren't the same thing.
A denture can do a lot, but "getting by" and "not thinking about it" are two very different experiences. If a few of these sound familiar, it's worth a calm conversation about what a fixed or implant-supported option could look like for you.
- A denture that shifts or clicks when you eat, laugh or speak.
- Foods you've quietly given up on because chewing feels unreliable.
- Adhesive you rely on daily just to feel confident it'll stay put.
- Most or all of the teeth in an arch missing, failing, or already replaced with a plate that no longer feels secure.
What All-on-X actually is.
All-on-X refers to a fixed, full-arch prosthetic supported by a small number of strategically placed implants — typically around four to six per arch, though the exact number depends on your bone volume and jaw shape. Rather than replacing each tooth individually, the whole arch is replaced as one connected, non-removable prosthetic.
Because it's fixed permanently to the implants, it functions much like a full set of natural teeth — no daily removal, no adhesive, no need to take it out overnight. It's a genuinely different approach from a conventional denture, and it's worth understanding the trade-offs against a removable implant-supported denture too, covered in the comparison below.
Two ways to add implant support to a full arch.
Both use implants to improve on a conventional denture — the honest difference is whether the result comes out at night or stays in permanently.
Implant-Supported Overdenture
A smaller number of implants than All-on-X support a denture that clips securely into place, adding real stability over a conventional denture while still coming out for cleaning each day.
Which option suits you depends on bone volume, general health, and how important a fully fixed result is to you personally. Suitability and results vary between individuals — confirmed together at your consultation.
What the visits look like.
Full-arch treatment involves more planning upfront, spread across a realistic number of appointments.
01
Consultation & 3D imaging
We assess bone volume across the whole arch and your general health, and talk through whether a fixed or removable implant-supported option suits you.
02
Any preparation needed
Bone grafting or a sinus lift is discussed if imaging shows it's needed — more common for full-arch treatment after years of tooth loss or denture wear.
03
Placing the implants
A small number of implants are placed per arch at planned positions, then given time to integrate before the final prosthetic is fitted.
04
Fitting your prosthetic
Your fixed arch or implant-supported overdenture is made, fitted and checked carefully for bite, comfort and appearance.
05
Review & ongoing care
Each supporting implant is reviewed at check-ups, helping catch any early signs of peri-implantitis.
What bone grafting actually involves.
After years of missing teeth, or long-term denture wear, the jawbone across an arch can gradually thin — without natural tooth roots to support it, bone simply resorbs over time. This is genuinely common in patients considering All-on-X or an implant-supported denture, more so than for a single missing tooth.
Bone grafting rebuilds volume at the sites that need it, creating a stable foundation for the implants that will support your prosthetic. 3D imaging across the whole arch tells us exactly where grafting is, and isn't, genuinely needed.
Any surgical or invasive procedure carries risks. Before proceeding, please seek a second opinion from an appropriately qualified health practitioner.
What a sinus lift actually involves.
For an upper-arch All-on-X or implant-supported denture, the maxillary sinus is a relevant factor for the back implant positions. In patients who've been missing upper back teeth for a long time, the sinus floor can sit close to the available bone, which is where a sinus lift comes in.
The sinus membrane is gently lifted and graft material placed beneath it, building the bone height needed for a stable implant position at the back of the arch. It's a well-established procedure specific to the upper jaw, and only recommended where your imaging shows it's genuinely required.
Any surgical or invasive procedure carries risks. Before proceeding, please seek a second opinion from an appropriately qualified health practitioner.
Looking after a full-arch prosthetic for the long run.
Because a fixed arch or overdenture relies on every one of its supporting implants, we check each implant individually at review appointments — inflammation around one (peri-implantitis) doesn't automatically mean the others are affected, and it's usually picked up early. Cleaning underneath a fixed prosthetic is part of what we'll show you, since it's different from cleaning natural teeth.
If peri-implantitis is found on any supporting implant, treatment can include laser-assisted decontamination of the affected surface, alongside a review of your home care routine. We offer dedicated peri-implantitis management across all three clinics — read the full peri-implantitis page for the detail →
Know the range before you ask.
Full-arch treatment is a bigger investment than a single implant, and it's fair to want the range upfront. Cost depends on whether you're considering a fixed All-on-X arch or a removable implant-supported overdenture, and whether bone grafting or a sinus lift is needed. We work with payment options that spread cost across smaller, regular amounts.

Estimate only — not a quote or credit approval. Your actual cost is confirmed at consultation, and depends on the number of implants and any bone grafting or sinus lift needed.
We accept
About the estimator: it gives an indicative figure only, based on a typical starting price per arch — it is not a quote. Every plan is priced individually once we've assessed your jaw with 3D imaging, and bone grafting or a sinus lift, if needed, is costed separately. You'll always see the exact cost in writing before agreeing to treatment. Repayment figures are illustrative, calculated by spreading the estimated total evenly across a Humm plan, and exclude any fees or charges Humm may apply; finance is subject to Humm's own eligibility criteria and approval, and is not guaranteed.
Care that talks you through it.
Fixed or removable, honestly compared
We lay out All-on-X and implant-supported overdentures side by side, so you choose based on what suits your life, not a sales pitch.
Bone mapped across the whole arch
3D imaging assesses volume across the entire jaw, so grafting or a sinus lift is only ever recommended where it's genuinely needed.
Reviewed for the long run
Every supporting implant is checked at regular reviews, with laser-assisted peri-implantitis care available if it's ever needed.
The things people usually ask.
All-on-X is a fixed, non-removable prosthetic permanently supported by implants, functioning like a full set of fixed teeth. An implant-supported overdenture is still removable — it clips onto a smaller number of implants for extra stability and security compared with a conventional denture, but comes out for cleaning. Which suits you depends on how much stability you want and your bone volume.
Typically around four to six implants support a full arch, though the exact number depends on your bone volume and jaw shape, confirmed with 3D imaging. This is fewer implants than replacing every tooth individually.
It depends on the bone volume across your arch, which we assess with 3D imaging. Bone loss is common after years of missing teeth or denture wear, so grafting or a sinus lift is discussed more often for full-arch treatment than for a single implant — but it's only recommended where imaging shows it's genuinely needed.
Each supporting implant is checked individually at review appointments, since the prosthetic relies on all of them working together. Laser-assisted decontamination can be used on an affected implant surface where appropriate — see our dedicated peri-implantitis page for the full detail.
Cost depends on the number of implants, whether bone grafting or a sinus lift is needed, and the type of prosthetic chosen. We'll only ever confirm an exact, written cost once we've assessed your jaw — you can also get a rough indicative figure using our repayment estimator on this page.
