What Are Full Arch Dental Implants? Fixed vs Removable Explained
How full arch implants work, fixed versus removable designs, suitability and timeline.
Checked by our editors. A dentist review of this article is planned but has not happened yet.
Full arch dental implants replace every tooth in the upper or lower jaw using a small number of implants, usually four to six, that hold a complete set of replacement teeth. The new teeth can be fixed in place or designed to snap on and off for cleaning.
The phrase covers several treatment designs, which is why clinic websites can seem to describe different things. This guide breaks full arch treatment into its parts, sets out who tends to be suitable and walks through a typical timeline so you can follow a consultation with confidence.
How do full arch dental implants work?
An implant is a small titanium screw placed in the jawbone that acts as an artificial root, according to the Oral Health Foundation. In a full arch plan, a handful of these roots share the job of supporting a whole row of teeth. Cleveland Clinic says full arch treatment usually uses four to six implants and may support non-removable dentures or dentures that snap on and off.
Names such as “All-on-4” or “All-on-6” describe particular versions of this idea. We compare them in our guide to All-on-4 dental implants.
Fixed or removable: what is the difference?
| Fixed full arch | Removable (snap-on) full arch | |
|---|---|---|
| Who takes it out? | Only the dental team | You, for daily cleaning |
| Feel | Closer to natural teeth | More like a denture, but held firmly by the implants |
| Cleaning | Interdental brushes and specialist aids around and under the bridge | Clean the denture out of the mouth and the implant fittings in the mouth |
| Typical use | Enough bone and a preference for teeth that stay in | Where easier hygiene or lower complexity is a priority |
Your dentist will recommend one based on your bone, bite and how you are likely to manage cleaning, so treat the table as a starting point for discussion.
Who is suitable for full arch implants?
Cleveland Clinic sets out the main checks:
- Age: typically at least 18, with no upper limit; your jaw must have finished growing.
- Bone: you need enough healthy jawbone, and a graft may be needed where bone has been lost.
- Gum and mouth health: active gum disease, extensive decay or poor oral hygiene can make implants unsuitable until treated.
- General health: unmanaged diabetes, some bone disorders and certain autoimmune conditions or medicines can raise the risk of complications.
- Smoking and vaping: these can disrupt healing.
What is the timeline for full arch treatment?
- Consultation and scans to check the jawbone and plan implant positions.
- Extractions and any grafting, if remaining teeth or bone need attention first.
- Implant placement. Cleveland Clinic says the first healing stage takes about a week.
- Integration. The bone fuses with the implants over roughly three to nine months, according to Cleveland Clinic. The Oral Health Foundation puts typical healing at about four months, and notes that in some cases teeth can be fitted the same day.
- Final teeth are made and attached once the implants are stable.

How long do full arch implants last?
Cleveland Clinic says the implant itself can last a lifetime with proper care, while the teeth on top wear sooner: around 15 years for crowns and bridges and at least seven years for dentures. The Oral Health Foundation adds that well-cared-for implants often last a very long time. Plaque around implants can cause peri-implantitis, which may lead to sore gums, infection and loosening, so daily cleaning and regular reviews matter as much as the surgery.
Is full arch treatment available on the NHS?
Only in limited circumstances. Guy’s and St Thomas’ NHS Foundation Trust offers implants to high-priority groups, including people missing all their teeth in one or both jaws where repeated conventional denture treatment has not worked. Most people pay privately; our full mouth dental implants price breakdown covers typical cost factors.
