All-on-5: what five implants mean for a full-arch restoration

A careful explanation of All-on-5, how implant count relates to the future restoration and why planning comes first.

Key points

  • All-on-5 describes a full-arch restoration supported by five implants, but the number five does not prove a clinical advantage by itself.
  • Support count follows 3D diagnostics, bone assessment, bite analysis and design of the future restoration.
  • Provisional and final materials, timing, maintenance and repair terms should be clarified separately.

How to use this guide

  • Do not choose five implants as a ready-made package; first obtain the restoration design and prognosis of every tooth that might be retained.
  • Ask to compare All-on-4, All-on-5, All-on-6 and removable options using the same diagnostic records.
  • Separate the provisional restoration, definitive prosthesis, maintenance and potential repairs.

What All-on-5 means

All-on-5 is a label used for a fixed full-arch prosthesis supported by five implants. It is not a specific implant brand or a universal standard for every patient.

The fifth support must have a defined position and purpose in the combined surgical and restorative plan. The clinic should confirm its protocol and relevant experience.

When full-arch restoration is discussed

It may be considered when most teeth are missing, remaining teeth have a poor prognosis, or a removable denture is unstable. The possibility of preserving each tooth should still be assessed.

The decision should not be based on promotional images or a package name. Gums, bone, bite, speech, hygiene and general health all matter.

Why there may be four, five or six supports

Implant number depends on bone volume, anatomy, restoration length and load distribution. More supports do not automatically mean a better outcome in every case.

The clinician should explain each proposed position on 3D imaging, expected primary stability and access for the prosthesis. A fallback plan should also be considered.

Provisional teeth and “teeth in a day”

When conditions allow, a fixed provisional restoration may be placed on the day of surgery. It provides appearance and limited function while tissues heal.

It is not the final prosthesis and does not mean unrestricted chewing. The definitive restoration is made after healing and the bite is reassessed.

What the plan and estimate should show

Diagnostics, extractions, implants, grafting, provisional prosthesis, abutments and definitive restoration should be identified. Ask about anaesthesia, reviews and maintenance as well.

Material, repairability, warranty terms and what happens if one implant develops a problem should be clear. Do not compare only the opening package price.

Care after full-arch treatment

The space beneath the prosthesis needs daily cleaning with suitable floss, brushes or an irrigator. Gums and tissues around implants require professional monitoring.

Arrange a review for bleeding, odour, movement, a loose screw or a bite change. Preventive maintenance is part of long-term care.

Questions to ask at your consultation

  • Why are exactly five supports proposed for my case?
  • Does the clinic have confirmed experience and cases using this approach?
  • Which materials are planned for the provisional and definitive restorations?

Frequently asked questions

Is All-on-5 better than All-on-4?

There is no universal answer. Selection depends on bone, restorative design and the clinic’s confirmed protocol.

Can I receive permanent teeth on the day of surgery?

A same-day restoration is usually provisional. The definitive prosthesis follows healing.

Can bone grafting always be avoided?

No. The need depends on anatomy and planned implant positions.

Can the prosthesis be repaired?

Some designs can be repaired, but this depends on material and the type of damage. Ask during planning.
