All-on-6 Dental Implants: Cost, Procedure and Results

What Are All-on-6 Dental Implants?

All-on-6, it's the full-arch technique where a fixed bridge rides on six titanium posts, replacing an entire upper or lower jaw. Four-implant versions have been around longer, but six posts shift how the load spreads. Chewing force doesn't just land on four points, it spreads across six. That difference matters when parts of the jawbone have thinned out, or when someone wants the longest possible lifespan from the investment.

The rear two implants go in at about a sixty-degree angle, pterygoid or pterygomaxillary engagement, they call it. That angled anchorage grabs denser bone further back, skipping the weaker ridge near the sinus. All-on-4 can angle its back implants too, but adding a fifth and sixth post gives a genuinely three-dimensional support. Simple math: three load-bearing posts per side instead of two. A prosthodontist in Knightsbridge put it this way: "Building on six pillars instead of four. Even if one pillar goes, you aren't scrambling."

The bridge itself is the same size as an All-on-4 bridge, ten to twelve teeth in one arch. Simple: a set of fixed teeth that don't come out for cleaning, feel stable, and can handle normal eating, no rocking like some patients get with fewer implants.

Who specifically needs six rather than four?

• Patients with a V-shaped narrow jaw, where four posts would crowd the anterior bone
• Cases where the surgeon wants primary stability (the initial grip) to be very high for immediate loading (teeth attached the same day)
• Heavy opposite-arch occlusion (natural teeth grinding down on an acrylic bridge)
• Jawbone resorption that's present but not enough to require grafting

For UK patients, the practical edge is plain enough, and six implants instead of four doesn't double the cost. It bumps the price roughly 20 to 30 percent over an All-on-4 case. But the added redundancy cuts the chance of late-stage failure.

All-on-6 vs All-on-4: Why Two Extra Implants Matter

The jump from four implants to six might sound small. It isn't. Those two extra implants alter the load distribution across your jaw so the structure feels more like natural teeth and less like a removable bridge glued in place.

Stability and bite force

Four implants can support a full arch-that's not in question. But the physics is simple: more contact points mean the chewing force spreads wider. With All-on-6, you get roughly 30-40% more surface contact between implant and bone compared to All-on-4. That extra grip matters when you bite into something hard-an apple (a steak) a crusty baguette. Patients tell me they trust a six-implant bridge more for everyday eating. They worry less about something shifting or clicking.

All-on-4 works best when bone density is decent in the front of the jaw. The rear implants are angled to grab what bone exists. All-on-6 places two straight implants further back, near the molar region. That posterior support is the real difference. It turns a cantilever bridge into something closer to a full-arch restoration, balanced support all the way around.

Who qualifies for each

Not everyone qualifies for six implants. Enough bone height are needed by You It also width in the back of the jaw to anchor those extra fixtures. If you've had years of bone loss from missing teeth, the posterior ridge might be too thin. A CBCT scan tells you everything in minutes.

So who typically gets All-on-6?

• Patients with moderate bone loss but enough posterior ridge depth are typical candidates.
• So are those who want maximum chewing stability for the long term.
• Younger patients who might need the bridge to last 20 years or more also fit.
• And anyone who has already lost lower molars and has reasonable bone there.

All - on-4 tend to work better for people with advanced bone loss, where the back of the jaw simply won't support a sixth implant.

Timeline and surgical load

Two extra implants add roughly 20-30 minutes to surgery time. That's the main trade-off, plus a bit more bruising and swelling over the first few days. By day seven, the recovery trajectory is nearly identical. The price gap usually sits between £1,500 and £3,000, that's for the two extra implants and the longer bridge framework.

Across clinics like implants knightsbridge and knightsbridge kensington, All-on‑6 is turning into the go‑to for patients with solid bone, fewer long‑term maintenance headaches. Fewer broken bridges, less prosthetic wear, chewing confidence goes way up.

Forget which technique looks better on paper.

It comes down to bone support for six implants and whether the extra cost fits your budget.

Who Is a Candidate for All-on-6 Implants?

Not everyone who wants fixed teeth is well‑suited for all‑on‑6 implants. Compared to All‑on‑4 (those two extra implants mean you need a bit more bone material) but they also distribute the load across a longer arch. So patients with restrained bone loss toward the back of the jaw can sometimes go this route, a narrower setup wouldn't hold.

What surgeons look for

Bone volume is still the top gatekeeper. You need at least 8-10 mm of vertical bone in the back sections, plus enough width for a 3.5-4 mm implant. A CBCT scan shows the team the exact spots where bone is thick enough. If the upper jaw is too shallow (a sinus lift can add height) but that adds 4-6 months to the timeline. For lower jaws, a nerve‑mapping scan makes sure the implants steer clear of the inferior alveolar nerve.

Your overall health matters just as much. Uncontrolled diabetes, heavy smoking (over 10 cigarettes a day), and untreated gum disease, these are common reasons we turn people away. Blood‑thinning medications, warfarin, high‑dose aspirin, usually get paused before surgery.

The All-on-6 Procedure: Steps, Timeline, and What to Expect

All‑on‑6 isn't a one‑appointment thing, and it's a sequence, stages that stretch over months. Knowing the order ahead of time helps settle the nerves.

Stage one: Consultation and planning

Before any cutting, you'll sit for a CBCT scan. That 3D image shows the surgeon where the bone is thick and where the nerve canals run. Blood work gets ordered too, checking for uncontrolled diabetes or clotting issues that would postpone surgery.

Stage two: Surgery day

You're under sedation or general anaesthetic, local alone is rare for six implants. Any hopeless teeth come out first. Then the surgeon places the six implants in a specific arch shape. Two front‑most implants go straight into the denser premaxilla bone. Back two angle forward to dodge the sinus and the maxillary nerve. That angulation is what sets All‑on‑6 apart from a simpler All‑on‑4, you're adding bite support further back without violating anatomical boundaries.

A single arch takes about 2.5 to 3 hours. Same‑day teeth? In most cases, yes. Before you leave, a prefabricated acrylic bridge gets screwed onto the implants. This isn't your permanent set, more a trial run that lets you eat soft foods while the bone heals around the titanium.

Stage three: Osseointegration (the quiet part)

Of all the stages, the healing phase is the longest. The bone needs 4 to 6 months to fuse with the implants. During that window you wear the temp bridge (skip anything crunchy) and don't bite directly on the front teeth. Check-ins happen around week two and week eight, quick x-rays to confirm nothing shifted.

Stage four: Final restoration

Once the surgeon confirms integration, impressions are taken for the permanent bridge. Milled zirconia or a porcelain-fused-to-metal hybrid, the material choice affects cost and feel. Five to ten days later, the temporary comes off and the final bridge gets torqued into place. Bite adjustment takes another 20 minutes, and don't skip that step.

Stage	Timeline	What you'll notice
Consultation	1 visit, ~60 min	Scans, bloods, treatment plan
Surgery	1 day, 2.5-3 hrs	Immediate temporary teeth fitted
Healing	4-6 months	Soft-food diet, check-ups at weeks 2 and 8
Final bridge	1 week for fabrication + 1 fitting visit	Permanent teeth, bite adjusted

What most people don't expect

Your speech will change. The tongue has to relearn where the roof of your mouth ends and the new teeth begin. Two weeks of lisping is normal. Because your mouth feels foreign, also normal: the first night's sleep is awkward. That fades.

People checking out implant clinics in Knightsbridge often assume the timeline is something they can bargain over. It isn't. The bone sets the schedule, not the dentist. London practices promising 'teeth in a day' without a proper healing phase are cutting corners.

Recovery, Pain, and Results After All-on-6 Surgery

All-on-6 recovery unfolds in two stages, and the first week is rough, no sugar-coating it. Most patients I've talked with describe days 2 through 4 as the worst. Swelling peaks around the 48-hour mark. Plan on a soft-food diet for roughly two weeks, longer if your jaw needed grafting on top of the implants.

Pain wise, and manageable with what your clinic prescribes. Paracetamol and ibuprofen handle most of it. Stronger opioids are rarely needed beyond day three. Cold compresses for the first 48 hours, then warm after that. Honestly, the mental adjustment to having a fixed arch of teeth is bigger than the physical pain for most people. You wake up with teeth that don't come out. It takes a bit of getting used to.

The real timeline breaks down like this

• Days 1-3: Try to rest as much as possible, and use ice packs regularly. A liquid diet is what you'll be on. Keep your head propped up when sleeping. Avoid spitting and using straws.
• Days 4-7: The swelling should start dropping, and now you can manage mashed potatoes, scrambled eggs, and soups. Stitches are still in.
• Weeks 2-4: Move to soft solids, and pasta, fish, steamed vegetables work well. If you got a temporary bridge, it might feel weird-that's normal.
• Weeks 5-12: Start adding firmer foods slowly, and steak isn't allowed yet. Nuts are also off the menu. Your bone is integrating around those implants, so take it slow. That part takes a solid three months.

Bruising sometimes works its way into the jaw and down toward the neck. Looks alarming, but that's just gravity at work, and by day twelve at the latest, it's gone.

What results look like

Somewhere around weeks four to six, most people feel back to normal, talking, smiling, sharing soft meals. If you had immediate loading, the permanent bridge goes on around month three or four. With delayed loading, you're looking at five to six months. What you get is a full arch of fixed teeth (no clicking) no slipping.
