The All-on-X Procedure: What to Expect, Step by Step

Dr. Nav Atwal

The All-on-X procedure runs in stages: a consultation with CBCT 3D scans and digital planning; the surgery day, when failing teeth are removed and four to six implants are placed, usually with a fixed temporary arch fitted the same day; a healing period of about three to six months while the implants fuse with the bone; and finally the fitting of the strong, custom final prosthesis. Most patients keep a fixed set of teeth throughout.

Key Takeaways

- All-on-X is a staged process over a few months, not a single appointment. - Planning uses CBCT 3D imaging and digital design for precise, guided implant placement. - On surgery day, failing teeth are removed, four to six implants placed, and a fixed temporary arch usually fitted the same day. - The implants then integrate with the bone over about three to six months. - The stronger, custom final prosthesis is fitted after healing — and you keep teeth throughout.

All-on-X is a planned sequence of stages rather than a single appointment. Knowing the path in advance removes most of the uncertainty: from the first scan to the final set of teeth, each step builds on the last, and in a well-run case you are rarely without teeth at any point.

Step 1: Consultation and 3D Planning

Everything begins with diagnostics. A CBCT scan produces a three-dimensional image of the jaw, showing bone volume, density, and the position of nerves and sinuses. Combined with digital scans and photographs, it lets the entire surgery be planned virtually before anything is done — implant position, angle, and depth all decided in advance.

Step 2: Treatment Design

Using that data, the case is designed as a whole: how many implants, where they sit, how the new teeth will look and function, and how they will support the lips and face. Where guided surgery is used, a custom surgical guide is produced so the plan transfers precisely to the day of treatment.

Step 3: Surgery Day

The surgical appointment, carried out under local anesthesia with sedation options, typically includes:

Removal of any remaining failing teeth in the arch
Placement of the four to six implants, often with two angled at the back for stability
Attachment of a fixed temporary arch, usually the same day

Most patients leave with a full set of fixed temporary teeth — the basis of the "teeth in a day" experience.

Step 4: Healing and Integration

Over roughly three to six months, the implants undergo osseointegration — fusing with the surrounding bone to form a stable foundation. During this time you wear the fixed temporary arch and follow a soft-food guidance period early on. This stage cannot be rushed; it is what gives the final result its strength.

Step 5: The Final Prosthesis

Once the implants are fully integrated, impressions or digital scans are taken and the definitive prosthesis is fabricated — typically a stronger, more refined acrylic-titanium hybrid or monolithic zirconia bridge. It is fitted, the bite is balanced, and the result is finalized for appearance and function.

Step 6: Maintenance

All-on-X is low-maintenance but not no-maintenance. Daily cleaning under the bridge and regular professional visits — where the prosthesis can be removed, cleaned, and checked — keep the result healthy for the long term.

Planned Precisely, Start to Finish

The smoothness of an All-on-X journey comes down to the quality of the planning behind it. In my practice, the surgical and aesthetic plan is built in detail before treatment begins, so every stage is predictable and the final result is designed from the outset. A consultation is the first step to seeing what your own plan would involve.

Frequently Asked Questions

How long does the whole All-on-X process take? From surgery to the final teeth it usually takes about three to six months, the time needed for the implants to integrate with the bone, though you wear fixed temporary teeth throughout. Is All-on-X really done in one day? The surgery and a fixed temporary arch are typically completed in a single day, but the strong final prosthesis is fitted later, once healing is complete. Is All-on-X surgery painful? The procedure is done under local anesthesia, with sedation options, so it is not painful during treatment. Some soreness and swelling afterward is normal and is managed with medication. Are the failing teeth removed the same day as the implants? Yes. Any remaining teeth in the arch are usually extracted during the same appointment in which the implants are placed. When do I get my final teeth? The final prosthesis is fitted after the implants have integrated with the bone, generally three to six months after surgery. How many appointments does All-on-X involve? Typically a consultation and planning visit, the surgical day, a few short follow-ups during healing, and the appointment to fit and adjust the final teeth.
