Full Arch Implants
A fixed, implant-supported replacement for a full arch of missing or failing teeth.
What full-arch implants are
Rather than placing an implant for every single missing tooth, a full arch of replacement teeth is supported by a small number of strategically placed implants — commonly four, which is why this is often called an "All-on-4" solution (some cases use more, sometimes described as All-on-X). A fixed prosthetic arch is then attached to those implants, giving you a full, natural-looking set of teeth that doesn't come out, unlike a denture.
How the implants are arranged
The placement is deliberately angled to make the most of the bone that's available and to avoid sensitive structures like nerves and sinuses:
- Two implants are placed toward the back of each side of the jaw, angled at roughly 30°
- Two implants are placed more vertically near the front of the jaw
- Together, this creates a secure, stable foundation for the full prosthetic arch — and often avoids the need for a bone graft that a straight, vertical placement might otherwise require
The "one-day smile"
In suitable cases, a temporary fixed bridge can be attached to the implants on the same day as surgery — meaning you leave with a functioning, good-looking set of teeth rather than going without while you heal. The final, permanent restoration is fitted once the implants have fully integrated with the bone, typically after a few months.
Benefits over traditional dentures
- Fixed in place — no clipping in and out, no slipping while eating or speaking
- Stronger bite force — chew the foods you actually want to eat, much closer to natural teeth
- Preserves jawbone — the implants stimulate the bone the way natural tooth roots do, which traditional dentures don't
- Natural appearance — designed to mimic the look of real teeth, which helps confidence as much as function
Longevity
Full-arch implant restorations are built for extended durability — with good care, a lifespan of 15 years or longer is realistic, compared to around five years for a traditional denture before it typically needs relining or replacing.
Is it right for you?
This option generally suits people who are missing most or all of the teeth in an arch, or who have multiple failing teeth that make sense to replace as a set rather than one at a time. A thorough assessment of your jawbone and general health is the first step — we'll talk you through whether you're a good candidate, and whether a bone graft is likely to be needed.
How many implants are used?
Typically four per arch, though some cases call for more, depending on bone volume and the specifics of your situation — we'll confirm the right number for you during planning.
Will I be without teeth while it heals?
Not if you're eligible for the same-day fixed temporary bridge — most patients leave the surgery with a functioning set of teeth already in place.
Is it the same as dentures?
No — unlike removable dentures, a full-arch implant solution is fixed in place. It functions much more like natural teeth, with significantly better chewing strength and no risk of slipping.
Will I need a bone graft?
Often not, because the angled implant placement makes efficient use of the bone that's already there — but it does depend on your individual bone volume, which we'll check with imaging beforehand.
How long does the whole process take?
Planning, placement and healing typically spans several months from start to the final restoration — we'll give you a realistic, personalised timeline at your consultation.
