What is All on 4 Dental Implants?

You’ve been told you need most or all of your teeth replaced, and the quote from a UK private dentist made your stomach drop. Then a friend mentions all on 4 dental implants and suddenly there’s a new option on the table. But what does it actually mean? Is it really a full set of teeth on just four screws? And is it as solid as it sounds?

Here’s the honest answer about all on 4 dental implants, written for UK patients who want the facts straight before booking a flight or signing on any dotted line.

What does All-on-4 actually mean?

All on 4 dental implants is a technique in which a full arch of replacement teeth—upper, lower, or both—rests on just four titanium implants set into the jawbone. The two rear implants are angled at roughly 30 to 45 degrees, and that tilt is really the whole secret. By angling them, the surgeon can anchor into the denser bone toward the front of the jaw while steering clear of the sinus cavities and nerves further back. The upshot? A bone graft usually isn’t necessary.

The concept was developed by Dr Paulo Maló in the 1990s and has been documented in long-term studies showing implant survival rates above 94% at 10 years when placed correctly.

Who is a good candidate?

This isn’t for someone missing just a tooth or two. It’s built for people who are losing—or have already lost—most of the teeth in an arch. Candidates typically include patients with:

• Advanced gum disease and multiple failing teeth
• An existing full denture they’ve grown tired of
• Significant bone loss that rules out conventional implants without grafting
• Heavy decay across most of one or both jaws

Smokers, people whose diabetes isn’t well controlled, and anyone taking certain bone-density medications should be carefully evaluated beforehand. Not sure where you stand? Having a professional look over your X-rays and CT scan is a must — and the All-on-4 service page is a good place to start for the clinical details.

How does the procedure work day by day?

Most patients wrap up their treatment in just two trips to Istanbul, spaced about 3-4 months apart.

First visit (4-7 days)

3D CT scan, extractions of any remaining hopeless teeth, placement of the four implants under local anaesthetic with sedation if needed, and fitting of a fixed temporary bridge. You leave with teeth the same day — this is the “teeth in a day” part everyone talks about. For the surgical detail, see same-day implants.

Healing phase (3-4 months at home in the UK)

The implants fuse with the bone—a process called osseointegration. During this time, you’ll wear the temporary bridge and stick to softer foods for the first 6-8 weeks, easing back to your normal diet from there.

Second visit (5-7 days)

The permanent bridge, typically made of zirconia or titanium-reinforced acrylic, is then fitted and fine-tuned.

How painful is it really?

The procedure is carried out under local anaesthetic, usually paired with IV sedation — so you’ll feel pressure, but not pain. Expect some swelling, bruising and a dull ache during the first 3-5 days, all of which respond well to ibuprofen and paracetamol. Most patients tell us it’s more uncomfortable than genuinely painful. By the one-week mark, the majority are tucking into soft food and no longer need any pain relief.

Why is it cheaper in Turkey than in the UK?

A full-arch set of all on 4 dental implants in the UK will usually set you back somewhere between £12,000 and £25,000 per arch if you go private. The NHS won’t cover implants, save for rare reconstructive cases. Head to Turkey for the same treatment — even with premium brands like Straumann or Nobel Biocare — and you’re typically looking at a fraction of those figures. That said, the actual cost hinges on your bone condition, which brand you go with, and whether extractions are part of the picture. Prices shift from case to case, so an examination is essential before any accurate plan can be drawn up.

The price gap comes down to lower clinical overheads, staffing costs and lab fees in Turkey — it’s not a sign of cheaper materials. Always ask which implant system you’re being quoted for. The brand counts for more than the country does.

What about aftercare once you’re back home?

Most patients tend to overlook just how wide this gap really is. Here’s what you’ll need after getting all on 4 dental implants:

• A UK dentist or hygienist visit every 6 months for professional cleaning around the bridge
• A water flosser at home — regular floss won’t reach under the prosthesis
• A night guard if you grind your teeth, to protect the zirconia
• An annual X-ray to check the bone level around the implants

Reputable Turkish clinics provide a written warranty on the implants and the bridge, plus a treatment record your UK dentist can follow. Ask for both before you travel.

All-on-4 vs All-on-6 — which is better?

Adding more implants helps distribute the chewing forces, which can be especially helpful in the upper jaw, where the bone tends to be softer. That’s why All-on-6 is often the go-to choice for the upper arch, whereas all on 4 dental implants perform beautifully in the lower jaw. When upper-jaw bone loss is severe, your dentist might bring up zygomatic implants as an alternative. Ultimately, the right call comes down to what your CT scan reveals — not just the price tag.

What are the realistic risks?

No implant procedure is entirely risk-free. The published failure rates hover around 2-5% per implant across a 10-year span. Potential complications include infection, loss of the implant, fractured screws, and chipping of the prosthetic teeth. Smoking roughly doubles the odds of failure. A solid surgical plan paired with an honest medical history can minimise these risks — though never fully eliminate them.
