The Procedure Explained

What Are All-on-4 Dental Implants?

All-on-4 is a fixed full-arch implant technique that uses four titanium implants per jaw to support a complete set of replacement teeth. The two rear implants are placed at an angle — typically 30–45 degrees — which distributes biting forces across the jaw and, crucially, allows treatment in patients who have experienced some bone loss without requiring bone grafting.

What It Is

Full arch of fixed teeth on four implants. Angled rear implants maximise bone contact without the need for grafting in most patients, making it suitable for a wider range of candidates than All-on-6.

UK Cost Range

From £9,500 per arch at standard clinics to £18,000 at premium practices. Full mouth (both arches) from £20,000. Finance available at most specialist clinics including 0% APR options.

Who It Suits

Patients with reduced bone volume who want to avoid bone grafting. Also ideal for those seeking the most cost-accessible full-arch fixed solution. A CT scan confirms suitability.

UK Pricing Guide

All-on-4 Cost UK — What to Expect

All-on-4 costs in the UK vary depending on clinic location, the implant brand used, prosthesis material (acrylic vs zirconia), and whether sedation is included. The figures below reflect the UK private market in 2024–2025.

Standard clinics outside major city centres tend to sit at the lower end of the range. Specialist implant practices in London and other cities charge premium rates that reflect higher overheads and experienced surgical teams.

Most UK clinics offer finance, including 0% interest-free options over 12–24 months, making the treatment accessible without requiring the full amount upfront. Always ask for a fully itemised written quote before committing.

The quote you receive should clearly state which implant brand is included, whether the prosthesis is acrylic or zirconia, what aftercare is provided, and any guarantees offered on the implants or prosthesis.

Step by Step

How the All-on-4 Procedure Works

All-on-4 spans several months from initial consultation to final prosthesis. Understanding each stage helps you plan your treatment realistically and know what to expect at every appointment.

Same-day teeth: All-on-4 is designed for immediate loading — you leave with a complete set of temporary teeth on the day of surgery, not weeks later.

1

Consultation & CT Scan

Appointment 1

Full assessment and cone beam CT scan to evaluate bone volume and jaw anatomy. Your clinician determines implant positions and confirms suitability for All-on-4.

2

Treatment Planning

1–2 weeks

Digital planning software maps precise implant positions based on your CT scan data. Pre-surgical extractions scheduled if any failing teeth remain.

3

Implant Surgery

3–4 hours

Four implants placed under local anaesthesia. Two front implants vertical, two rear implants angled at 30–45° to maximise bone contact and avoid the need for grafting.

4

Temporary Teeth

Same day

A full-arch temporary prosthesis is fitted the same day as surgery. You leave the clinic with a complete set of functional teeth.

5

Osseointegration

3–6 months

Implants fuse with bone over 3–6 months. Dietary restrictions apply during this period. Monitoring appointments ensure healing is progressing correctly.

6

Final Prosthesis

Final appointment

Permanent prosthesis — acrylic or zirconia — fabricated and fitted after osseointegration is confirmed via X-ray or CT scan. Final bite adjustments completed.

Treatment Comparison

All-on-4 vs Other Treatments

All-on-4 vs All-on-6

All-on-6 uses six implants in a more upright configuration, distributing load across a wider area and typically requiring more available bone. All-on-4's angled rear implants make it suitable for patients with reduced posterior bone volume — often without grafting.

All-on-4 vs Dentures

Conventional dentures rest on the gum, can move when eating or speaking, and do not prevent bone resorption. All-on-4 is fixed, functions like natural teeth, and stimulates the jawbone. The functional and aesthetic difference is significant.

All-on-4 vs All-on-8

All-on-8 uses eight implants for maximum stability in patients with strong bone density. For most patients, All-on-4 or All-on-6 provides excellent outcomes. The right number of implants is determined by your CT scan, not by personal preference.

Common Questions

All-on-4 Questions Answered

How much does All-on-4 cost in the UK?
All-on-4 in the UK typically costs between £9,500 and £18,000 per arch depending on the clinic, implant brand used, and prosthesis material. Full mouth treatment (both arches) ranges from £20,000 to £36,000. Finance options including 0% APR are available at most specialist clinics.
What is the difference between All-on-4 and All-on-6?
All-on-4 uses four implants per arch, with the two rear implants placed at an angle to avoid bone grafting in areas of reduced bone volume. All-on-6 uses six implants in a straighter configuration and typically requires more available bone but distributes load across a wider area. The best option depends on your bone volume as assessed on a CT scan — neither is universally superior.
Is All-on-4 available on the NHS?
All-on-4 dental implants are not available on the NHS in most circumstances. The NHS classifies full-arch implant treatment as elective, meaning it falls outside standard NHS clinical criteria. Exceptions exist for patients who have lost teeth as a result of cancer treatment, trauma, or certain congenital conditions.
How long does All-on-4 last?
The titanium implants, if they integrate successfully and are well maintained, can last 20 years or more — some studies show lifetime integration. The prosthesis on top has a shorter lifespan: acrylic prostheses typically need replacement or refurbishment every 5–10 years, while zirconia prostheses can last 15–20 years with proper care.
Can All-on-4 be done in one day?
Yes, in most cases. All-on-4 is specifically designed for immediate loading — meaning a temporary full-arch prosthesis is fitted on the same day as implant surgery. This is why it is also referred to as 'teeth in a day' or 'same day teeth'. The temporary prosthesis is replaced with a permanent one after the 3–6 month osseointegration period.
What implant brands are used for All-on-4 in the UK?
Nobel Biocare developed the original All-on-4 concept, and many UK clinics use Nobel Biocare or Straumann implants for this treatment. Other internationally recognised brands including Zimmer Biomet and Dentsply Sirona are also used. Ask any clinic to confirm the specific implant brand and system before committing to treatment.
