Why is a 3D scan needed before All-on-4?

A 3D scan, usually a CT scan, shows the shape, height and quality of your jawbone in detail. The dentist uses it to decide whether All-on-4 is possible and where the four implants should go, including the angle of the back implants. It can also show whether extra steps such as bone grafting or a different implant approach might be needed in your case.

Will I leave the clinic with teeth on the day of surgery?

Many patients receive a temporary fixed bridge shortly after surgery, but this depends on how stable the implants are when they are placed. If the dentist feels the implants need more time before carrying a bridge, a different temporary solution may be used. Your clinic should explain during planning what you can realistically expect on surgery day.

Is the All-on-4 surgery painful?

The surgery itself is usually done under local anaesthesia, often combined with sedation, and sometimes under general anaesthesia, so you should not feel pain during it. Afterwards, swelling, bruising and discomfort are common for the first days. These are usually managed with medicines prescribed by your dentist. How much discomfort you feel varies from person to person.

Why do I need to wait before getting the final bridge?

The implants need time to bond with the jawbone before they can reliably carry a stronger, permanent bridge. This healing phase often lasts a period of months, though the exact timing depends on your bone, your general health and how healing progresses. Your dentist checks the implants before deciding when the final bridge can be made and fitted.

How many trips abroad does All-on-4 usually involve?

Often two trips are planned. The first usually covers the examination, scans, surgery and fitting of the temporary bridge. The second, after the healing period, is for making and fitting the final bridge and adjusting your bite. Some cases need a different plan, so ask the clinic to explain the number of visits and expected length of stay for your situation.

All-on-4 Procedure Steps: From 3D Scan to Final Bridge

Published October 12, 2026

Find out what happens at each stage of All-on-4 treatment, from the first consultation and 3D scan to surgery, temporary teeth, healing and the fitting of your final fixed bridge.

All-on-4 Procedure Steps: From 3D Scan to Final Bridge

If you are thinking about replacing a full arch of missing or failing teeth, knowing what lies ahead can make the whole journey feel more manageable. All-on-4 dental implants use four implants in the jawbone to hold a fixed bridge, so you are not relying on a removable denture. This guide walks you through the typical all-on-4 procedure steps, from the first 3D scan to the moment your final bridge is fitted.

Every treatment plan is individual. The order of steps described here is a common pattern, but your dentist will explain what applies to you, how long each stage may take in your case, and whether All-on-4 is a suitable option at all.

Step 1: Consultation, 3D Scan and Treatment Planning

Everything starts with planning. This stage is where the dentist works out whether All-on-4 is right for you and how the implants should be placed.

A planning appointment usually includes:

An examination of your mouth, gums, remaining teeth and bite
X-rays or a CT scan, which gives a 3D view of your jawbone
A review of your medical history, including any medicines you take
A conversation about your goals, such as how you want your teeth to look and feel

The 3D scan matters because it shows the amount and quality of bone in your jaw. With All-on-4, the two back implants are often angled to make the most of the bone that is available, which can reduce the need for bone grafting in some patients. If there is not enough bone, the dentist may suggest a different approach, such as bone grafting, more implants or another type of implant.

The dentist will also look at factors that can affect healing, for example uncontrolled diabetes, smoking, medicines that affect bone or blood clotting, and teeth grinding. Being open about your health at this stage helps the team plan safely.

Step 2: Surgery Day and Implant Placement

All-on-4 is normally an outpatient procedure, which means you go home the same day. It is usually done under local anaesthesia, often with sedation, and sometimes under general anaesthesia. Your dentist will discuss which option suits you.

On the day of surgery, the main all-on-4 procedure steps are typically:

Removing any remaining teeth that cannot be saved
Preparing the jawbone where the implants will go
Placing two straight implants at the front of the jaw
Placing two angled implants further back, using the available bone
Closing and protecting the gum around the implants

Having a clear picture of this sequence beforehand can help ease nerves. Ask your clinic what to eat beforehand, whether you need someone to accompany you, and what to bring.

Step 3: Fitting the Temporary Bridge

In many cases, a temporary fixed bridge is attached soon after surgery, as long as the implants are stable enough. This provisional bridge is lighter than the final one. It lets you leave with fixed teeth while the implants heal underneath.

A few things are worth knowing about the temporary bridge:

It is designed for the healing phase, not for long-term use
You will usually need to stick to soft foods and avoid chewing anything hard on it
It can wear or break, so following your dentist's advice on eating is important
Not every patient receives one immediately; this depends on how stable the implants are

Step 4: Healing While the Implants Bond With the Bone

This is often the longest part of treatment. Over a period of months, the implants gradually bond with the jawbone. This process is what gives them the stability needed to carry the final bridge.

In the first days after surgery, most people have swelling, some bruising and discomfort. This is usually managed with medicines prescribed by the dentist. Helpful habits during this phase include:

Resting after surgery and following all aftercare instructions
Using cold packs and taking medicines exactly as prescribed
Eating soft foods
Keeping the area clean as instructed, often with gentle rinses
Avoiding smoking, as it can slow healing
Attending every check-up, including remote follow-ups if you have travelled

How quickly you recover differs from person to person, so try not to compare your progress with someone else's.

Step 5: Fitting the Final Bridge

Once the implants have healed, the final bridge is made. It is stronger and custom-made for you. The dentist takes new impressions or scans, checks the fit, and adjusts your bite so that chewing feels balanced.

Final bridges can be made from different materials, such as acrylic, composite, zirconia or a metal framework. Your dentist can explain the pros and cons of each for your situation.

After the final bridge is fitted, long-term care becomes part of daily life:

Daily cleaning around the bridge and implants, as shown by your dental team
Regular professional check-ups, just as you would have for natural teeth
Telling your dentist early if anything feels loose, sore or different

Thorough cleaning matters because gum inflammation around implants, known as peri-implantitis, can develop if plaque builds up.

How the Steps Fit Together When You Travel Abroad

If you have treatment abroad, the stages are often spread over two trips. The first trip usually covers planning, surgery and the temporary bridge. The second trip, after the healing period, is for the final bridge and bite adjustments.

Before booking, it helps to ask:

Who will carry out the surgery, and how much experience do they have with full-arch implants?
Is a 3D scan part of the planning?
Which implant system is used, and can it be serviced in your home country?
How many trips are needed, and how long should you plan to stay?
How is follow-up handled once you are back home?

Costs depend on your individual plan and can only be confirmed after an examination. Asking for a written breakdown makes it easier to see what each quote includes.

When to Talk to a Doctor

All-on-4 is an established treatment, but like any surgery it carries risks. These can include infection, implants that do not fuse with the bone, nerve irritation causing numbness or tingling, sinus problems with upper jaw implants, and wear or breakage of the bridge. Good planning and careful aftercare help lower these risks, but no clinic can rule them out completely.

Contact your dentist or clinic promptly if you notice:

Pain or swelling that gets worse instead of better
Fever, pus or a bad taste that could suggest infection
Bleeding that does not settle
Numbness or tingling in the lip or chin that does not go away
A bridge or implant that feels loose or cracked

If you have a long-term health condition or take regular medication, talk to your own doctor before treatment too. Suitability, recovery and risks differ for everyone and should always be discussed with the treating dentist.

When you feel ready to explore your options, you can compare verified clinics, read about their planning and aftercare, and send one free request so clinics can contact you with their suggestions.
