How long does All-on-4 take? Planning the calendar from first appointment to final bridge

All-on-4 is measured in months, not weeks — and almost all of that time is waiting rather than treatment. The operation itself takes roughly 60 to 120 minutes per jaw, and where the implants sit firmly enough on the day, you go home with a fixed temporary bridge. Then comes the part that cannot be hurried: a healing phase of three to six months while bone bonds to the implants, before the definitive bridge is made and fitted. Around that sit two shorter phases people forget to budget for — diagnostics and planning at the start, and the approval wait while your health insurance fund processes the treatment and cost plan (Heil- und Kostenplan, HKP) before treatment may begin — how long that takes varies from fund to fund. If you are trying to fit this around a job, a move or a flight home, that is the shape you are planning against.

Everything else on the calendar is negotiable. This is not.

An implant is not a screw in a wall. After placement, bone cells grow onto and into the implant surface until the implant is locked in living bone. That process — osseointegration — takes months, and it runs at the speed of your biology, not your diary. Three to six months is the usual span, and where it lands within that range depends on bone quality, on whether a bone graft (Knochenaufbau) was involved, on your general health, and on habits like smoking.

Understanding this changes how the whole treatment feels. Patients who expect “teeth in a day, finished” grow impatient in month two. Patients who understand that they are wearing a functioning temporary bridge while their jaw does its work tend to find those months uneventful, which is exactly what they should be.

Add those up and you see why “how long does it take” has no single answer: the healing phase dominates, and phases 1 to 3 can be brisk or slow depending on your findings and your fund.

This is the phase you control most, and the one worth not rushing.

The first consultation with us is free. It is an assessment, not a sale: what is the condition of the remaining teeth, what does the gum look like, what has already been tried, what do you actually want at the end of it. If a full arch is a realistic route, the next step is imaging.

A 3D X-ray (DVT) is not optional for this kind of planning. Placing tilted implants safely means knowing exactly where the maxillary sinus sits in the upper jaw and where the nerve canal runs in the lower one — and a flat X-ray shows height but not width. A DVT costs 178 € in our practice.

Alongside it, a digital scan with Primescan records the shape of the jaw and the bite. No trays, no impression material setting in your mouth — which matters a great deal to patients with a strong gag reflex.

Then the planning itself happens on a screen: implant positions are placed virtually, in your anatomy, with the finished teeth already in the picture, and the plan is transferred into a surgical guide. Software also flags findings on the images for the dentist to review — support for the assessment, never a substitute for it.

How long all of this takes is mostly a scheduling question. Several appointments can often be combined; if you are travelling in from Düsseldorf, Cologne or Bonn — and patients do travel for this, from across NRW and from further afield in Germany — say so when you book, and we will try to put the imaging and the consultation on the same day.

This is where timetables slip, and it has nothing to do with dentistry.

The HKP goes to your statutory fund and must be approved before treatment starts. Begin first and the entitlement to the fixed subsidy (Festzuschuss) is lost. How long the fund takes to process it varies from fund to fund.

Practical consequences for your calendar:

• Do not book the surgery date before the plan has gone in. Or rather: book it far enough out that the answer will have arrived.
• Holidays slow funds down, like every other office in Germany. A plan submitted just before Christmas or in August may sit longer.
• Private insurance adds its own loop. If you have private health insurance (PKV) or a supplementary dental policy (Zahnzusatzversicherung), send them the cost estimate and get the reimbursement confirmed in writing. That correspondence runs in parallel, not afterwards.

If preliminary treatment is needed — gum disease brought under control, teeth removed — that often fits neatly into this waiting window rather than adding to the total.

The operation is shorter than most people expect, and the day around it is longer.

Arrival and preparation. Checks, the local anaesthetic (Betäubung), and — if you have chosen it — sedation or laughing gas (Lachgas). Anxious patients should ask about this at the planning stage rather than on the morning; it changes the arrangements, not the treatment.

The surgery itself. Any teeth that need removing come out, the implants are placed through the surgical guide, and the connectors are attached. Roughly 60 to 120 minutes per jaw. Guided placement is part of why that figure is what it is: the decisions were made in the planning software, so the time in the chair is spent executing them.

The temporary bridge. Where the implants are firm enough at that moment, the fixed temporary is fitted the same day — usually after a wait while it is adapted. This is why the appointment occupies most of a day even though the operation is measured in minutes. Where stability is not sufficient, immediate loading is not sensible, and your dentist will say so and explain the alternative. That is a judgement made for good reasons, not a complication.

Going home. If you had sedation, you must not drive, and you need someone with you. Plan that before the day, not on it.

Both jaws? Treating upper and lower in one session means one recovery instead of two, but a more demanding day and a stricter diet phase, because you have nothing firm to chew against. Splitting them is gentler and stretches the calendar. There is no universally right answer — it is worth discussing openly at planning, including how it affects your work.

This is the long middle, and for most people it is uneventful.

What you notice. Swelling peaks around day two or three and then subsides. Speech feels odd for a week or two. Eating is soft for a fortnight and then gradually returns to something like normal — the full food timetable is here: Can you eat straight away with All-on-4? What works on day one and what needs patience.

What you do. Keep the appointments. There are check-ups in these months, and the temporary bridge sometimes needs adjusting as the gum settles into its final shape. Clean under the bridge daily with the tools you were shown. Stop smoking if you can — nothing else you do in this period has as much influence.

What is happening underneath. Bone is remodelling around each implant. You cannot feel it, which is precisely why the schedule is set by the dentist and not by how well you feel.

Why three to six and not a fixed number. Denser bone in the lower jaw generally integrates faster than softer bone in the upper. A graft adds its own healing time. Diabetes, smoking and some medications slow things down. Your dentist decides when the implants are ready by examining them, not by counting weeks on a calendar.

The final bridge is not one appointment. Expect a short series across some weeks:

• Recording. A digital scan or impression of the healed situation, with the implant positions registered precisely.
• Bite and try-in. How the teeth meet, how they look, how they sound when you speak. This is your chance to say something is not right — shape, shade, length. Say it now, at the try-in stage, when changing it is straightforward.
• Laboratory work. The framework and the tooth arch are made. Our own master dental laboratory (Meisterlabor) is in the building, which shortens this loop and means the technician can look at your face rather than a photograph.
• Fitting. The bridge is screwed on, the bite is adjusted, the screw channels are closed.
• A check shortly afterwards. Small adjustments in the first weeks are normal, not a sign that something went wrong.

How long the whole phase takes depends on the material, the number of try-in stages and — honestly — on how quickly appointments can be found in both your diary and ours.

Once the bridge is in, the treatment is finished and the maintenance begins.

Recall appointments, professional cleaning (professionelle Zahnreinigung, PZR) adapted to implants, and periodic checks of the screws and the tissue around the implants. Reported implant survival sits at around 95 % and above in the studies — and those results belong to people who come back for check-ups and clean under the bridge every day. We give a 2-year warranty on dentures; what it covers in a specific case is a conversation to have before treatment.

A bone graft. Where one is needed, it brings its own healing period before or alongside implant placement.

Gum disease that is still active. Periodontitis has to be under control before implants go in. Treating it first is not a delay, it is a precondition.

Slow approval. Processing times differ between funds, and they run longer over holiday periods.

Smoking. It is the most consistently unhelpful factor in implant healing, and the weeks around surgery are where stopping does the most good.

Diabetes and general health. Well-controlled diabetes is not a barrier to implants; poorly controlled diabetes slows healing. Blood-thinning medication, bone-related medication and immune conditions all need to be on the table at planning, because they influence both the plan and the pace.

An implant that does not integrate. Uncommon, but possible. It means a step backwards and a new healing period, and it is one of the things to discuss in writing at the planning stage.

Your own diary. More timetables slip because of holidays and business travel than because of biology.

This is the part most articles leave out, and it is the part expat patients ask about most.

Time off work. Full-arch surgery is not a lunchtime appointment. Plan for the rest of that day and a quiet couple of days after, more if your job is physical or involves a lot of speaking. A dentist in Germany can issue a sick note (Arbeitsunfähigkeitsbescheinigung) where it is medically justified — ask on the day rather than afterwards.

Book the surgery early in the week or before a weekend. Many people prefer a Thursday, so the swelling peak falls on days when they are at home anyway. We are open Monday to Friday 07:30–19:30 and Saturday 08:00–18:00, and early appointments are the easiest to fit around a working day.

Do not book a long-haul flight for the days right after surgery. Give yourself a clear window afterwards, and keep the first follow-up appointments free.

Trips home. If you visit family abroad every year at the same time, put that in the plan at the first consultation. The healing phase is flexible about where you are — it is the surgery and the fitting appointments that need you in Wuppertal.

Moving away during treatment? Say so early. A treatment plan that will end in another city is a plan that should be designed differently from the start.

The commute. From Düsseldorf, Cologne or Bonn it is a manageable journey, and most of the appointments in the healing phase are short. Cluster them where possible; ask us to.

Long treatments have a lot of appointment-making in them, and that is where the language barrier actually bites — not in the surgery itself but in the phone call, the reminder letter, the sick note, the fund’s approval letter.

Practical points: ask for your appointment card and post-operative instructions in English; photograph anything from your fund and bring it to your next visit; and tell us at the outset if you have fixed travel dates. We treat patients in English routinely, along with German, Russian, Turkish, Ukrainian, Arabic, Kurdish and French, and it is much easier if the appointment is planned for that from the start.
