All-on-X replaces a full arch of missing teeth using four, six, or more implants depending on your bone and needs, with a temporary fixed prosthesis attached at the time of surgery and a permanent one placed after healing. It is designed for patients with significant tooth loss who want a fixed alternative to removable dentures, without the extensive bone grafting older techniques often required. At Sola Dental Spa in Staten Island, our team determines the right number of implants for your case using CT imaging before any surgery happens.
What is All-on-X, exactly?
All-on-X is a full-arch implant technique that replaces all of the teeth on the upper or lower jaw using a set of implants, most often four or six, though the exact number depends on your bone volume and oral health. Unlike placing implants one at a time, All-on-X restores the whole arch in a coordinated procedure, with a temporary fixed prosthesis attached to the implants right away.
What happens during the procedure?
| Step | What It Involves |
|---|---|
| CT imaging | Determines bone volume and the best position for each implant |
| Treatment planning | Teeth are designed from the scan to fit your jaw and bite |
| Extractions and implant placement | Damaged teeth are removed and 4 to 6 implants are placed |
| Temporary prosthesis | A fixed temporary set of teeth is attached for immediate function |
| Healing | Roughly 3 months for the implants to integrate with bone |
| Permanent restoration | The temporary prosthesis is replaced with a custom permanent one |
Once the implants have fully integrated with the bone, the temporary structure is replaced with a permanent one built to last for many years with proper care.
Is All-on-X the same as All-on-4?
They are closely related but not identical. All-on-4 always uses exactly four implants placed in specific, pre-planned positions in the jawbone. All-on-X does not fix the number in advance; your dentist determines whether four, six, or another number of implants will give the most secure, comfortable result based on your CT scan and the condition of your jawbone. Both techniques aim for the same outcome: a fixed, natural-looking arch of teeth and restored chewing function.
What does All-on-X cost?
| Material | Estimated Cost per Arch |
|---|---|
| Standard acrylic or composite prosthesis | $20,000 to $26,000 |
| Individual porcelain teeth | $30,000 and up |
Cost depends on the material chosen, the number of implants placed, and the condition of your jawbone. Porcelain generally lasts longer and is simpler to repair than acrylic. Many dental insurance plans cover part of the cost because All-on-X is considered a restorative rather than purely cosmetic procedure, so it is worth confirming your specific benefits before treatment.
Who is a good candidate for All-on-X?
All-on-X is generally recommended for patients dealing with:
- Significant or complete tooth loss in an arch
- Noticeable bone loss that complicates traditional implants or bridges
- Failing bridge work with a poor long-term outlook
- Active periodontal disease affecting the remaining teeth
It is not intended for replacing a single missing tooth, which is better addressed with a standard dental implant.
“The reason All-on-X works so well for patients with significant bone loss is that we are not trying to force implants into areas that cannot support them. We plan the number and angle of implants around the bone that is actually there, which is why the results hold up long term.”

Is All-on-X suitable for older patients?
Yes, and it is often especially well suited to them. All-on-X requires only a small amount of local anesthesia and places implants into the deepest, hardest layer of the jawbone, which resists the natural bone loss that comes with age, so the implants stay firmly anchored. Age alone does not disqualify a patient; adults in their sixties, seventies, and beyond routinely qualify as long as their overall health and bone volume support the procedure.
Frequently asked questions
How many implants does All-on-X use?
It varies by patient, most commonly four or six, determined by a CT scan of your jawbone and your dentist's treatment plan.
How long does recovery take?
Initial healing before the permanent restoration is placed generally takes about three months, though this varies by patient.
Will my dental insurance cover All-on-X?
Many plans cover part of the cost since it is considered restorative rather than purely cosmetic, but coverage varies, so confirm your specific benefits beforehand.
Is All-on-X painful?
The procedure is performed under local anesthesia, and most patients report manageable discomfort afterward rather than significant pain.
How is All-on-X different from traditional dentures?
All-on-X is fixed to implants in the jawbone rather than resting on the gums, so it does not require adhesive and does not shift while eating or speaking.
What is recovery actually like?
Most patients experience swelling and soreness for the first several days, manageable with prescribed or over-the-counter pain relief, and are back to normal activities within a week. A soft-food diet during the initial healing phase protects the temporary prosthesis while the implants begin to integrate with the jawbone underneath.
Can I still get All-on-X if I wear dentures now?
Yes, many All-on-X patients are current denture wearers who are tired of slipping, adhesive, or the maintenance routine, and the transition typically starts with a CT scan to assess remaining bone volume.
What happens if an implant fails?
Implant failure is uncommon when a case is well planned, but if it happens, the affected implant can typically be removed and replaced once the site heals, without affecting the rest of the prosthesis.
