Full-arch restoration
A full arch on four or six implants
The name behind your smile.
When an arch has no teeth left, or the remaining teeth cannot be saved, four or six implants can carry a fixed bridge. This is major surgical and restorative treatment — not a one-day service.
The difference patients actually feel
A complete denture rests on the gum and is held by it. Chewing force drops sharply, taste changes, and bone continues to resorb underneath.
A fixed bridge on implants transfers load into the bone. It does not come out, does not move when you speak, and needs no adhesive. For most patients that is the difference between wearing teeth and having them.
When four implants, and when six
Four implants — the two rear ones angled — often avoid the sinus and the softer posterior bone, frequently without grafting. Six implants spread load across more supports and leave reserve if one is lost over the years.
The choice is made on the scan, against bone volume, bone quality and the opposing arch. Both are the same decision with the same goal, which is why we discuss them on one page rather than selling them as two products.
Provisional and definitive bridges
You usually receive a fixed provisional bridge within days of surgery, so you do not leave without teeth. It is functional but not final.
The definitive bridge is made once tissues have settled — typically after three to six months — and that is when final aesthetic adjustment happens.

Stages of treatment
Stages and realistic timing
For most patients the whole process runs between four and eight months.
Diagnostics
CBCT, assessment of remaining teeth, periodontal status, planning of implant positions. This is where four versus six is decided.
Surgery
Removal of unsalvageable teeth, levelling of the ridge, implant placement — usually in one session per arch.
Provisional bridge
A fixed temporary bridge so you can function and look normal while bone heals.
Healing
Three to six months, with dietary restrictions and review appointments.
Definitive bridge
Digital impressions, try-ins, the final bridge, and maintenance instruction.
What the evidence shows
98.1%
implant survival with All-on-4 at 5+ years
Systematic review and meta-analysis of 55 studies (2026): 98.14% for All-on-4 and 97.50% for All-on-6. Mechanical complications 5.91% and 6.64%; biological 6.54% and 7.41%. In a 10–18 year series of 471 patients, cumulative implant survival was 93% and prosthesis survival 98.8%.
~22%
peri-implantitis prevalence at patient level
Pooled meta-analytic estimate (95% CI 14–30%); peri-implant mucositis approximately 43%. A later meta-analysis of 57 studies estimated 19.5% at patient level. Reported prevalence ranges from 1% to 47% because case definitions differ, and rises with time in function.

Who this is for
Who this is for
- An edentulous arch, or teeth with a poor long-term prognosis
- Sufficient bone in the anterior part of the jaw
- Patients who cannot tolerate a removable denture
- Willingness to attend professional maintenance twice a year
Good to know
- Active untreated infection
- Severe uncontrolled systemic disease
- Inability to clean underneath a fixed bridge
- An expectation that the result needs no maintenance
Good to know
What you should know in advance
A systematic review and meta-analysis of 55 studies reports pooled implant survival of 98.14% for All-on-4 and 97.50% for All-on-6 at five years or more. Mechanical complications, however, are not rare: 5.91% and 6.64% respectively — and in a long-term series of 471 patients followed for 10 to 18 years, mechanical complications occurred in 36.7% of cases.
In plain terms: the implants usually stay. It is the bridge on top — a fractured tooth, debonded veneering, wear — that most often needs attention over the years. Budget for that as part of the cost, not as a surprise.
Hygiene under a fixed bridge is harder and needs specific tools. Patients who cannot or will not maintain it are better served by another solution.
Alternatives
Alternatives
Implant-retained overdenture
Fewer implants, lower cost, removable for cleaning. A compromise on stability.
Conventional complete denture
The most affordable option. The least comfortable, and bone resorption continues.
Individual implants and bridges
Where some of your own teeth are salvageable, this is sometimes a better answer than clearing the arch.

Frequently asked questions
Frequently asked questions
In most cases a fixed provisional bridge is fitted within days of surgery, and sometimes on the day itself. Whether that is possible depends on the primary stability measured during surgery — it is not promised beforehand.
Cost is built from the implants, the provisional bridge, the definitive bridge and any bone preparation. The provisional bridge is €750 for All-on-4 and €1,000 for All-on-6; implants are €650 (Neodent) or €950 (Straumann) each. The total for your case follows the scan and planning, and you receive it in writing.
Studies report high implant survival at five to ten years alongside frequent mechanical complications in the prosthesis over time. Realistically: the implants usually stay; the bridge above them is repaired or replaced over the years.
A fixed bridge does not cover the palate, which most patients describe as a more natural sense of taste and easier speech than a complete denture. The first weeks still require adaptation.
With All-on-4, angling the posterior implants often avoids a sinus lift. “Often” is not “always” — that is what the scan is for.
