What is All-on-4 and who is it for?
All-on-4 (All on four) restores a jaw in which all teeth are missing or need to be extracted, using a fixed prosthesis placed on four implants. It is often chosen in the following situations:
- People who wear removable dentures and want to get rid of their dentures,
- People whose teeth are loose and about to be lost due to advanced gum disease,
- Patients with bone loss in the back areas who do not want, or are not suitable for, a bone graft or sinus lift,
- Patients who want fixed teeth quickly and for whom fewer surgical procedures are the goal, for example in implants for elderly patients.
Suitability is determined by bone volume, general health (e.g. well-controlled diabetes), smoking and gum health, through a periodontal assessment and 3D CT scan.
The All-on-4 treatment process step by step
- Examination and 3D CT scan: Bone height and width, and the position of the sinuses and nerves are assessed.
- Digital planning: Implant angles and prosthesis design are planned with digital impressions and smile design.
- Surgery day: Any necessary extractions are carried out and four implants are placed. The procedure is performed under local anaesthesia; sedation can be considered for anxious patients.
- Immediate loading: If adequate primary stability is achieved, temporary fixed teeth are fitted on the same day or within a few days.
- Permanent prosthesis: After healing and osseointegration, the permanent bridge is made. Depending on preference, an acrylic-titanium hybrid or zirconia prosthesis is fitted.
How long does All-on-4 take, and how many days until it is finished?
In suitable cases, surgery and temporary fixed teeth can be completed on the same day. For the permanent prosthesis, bone healing must be awaited; this period varies from patient to patient and usually takes a few months. Whether additional procedures are needed determines the exact timeline.
All-on-4, All-on-6 or individual implants?
| Option | Key feature | Suitable for |
|---|---|---|
| All-on-4 | Fewer implants, angled placement, often without grafting | People with bone loss in the back areas |
| All-on-6 | Force is distributed over 6 implants, broader support | People with sufficient bone volume and strong chewing force |
| Individual implants | A separate implant for each tooth, the most natural feel | People with suitable bone and budget |
| Removable denture | The most economical | People who do not want or are not suitable for surgery |
All-on-4 prices 2026: what determines the cost?
The price of All-on-4 cannot be given as a single figure; the following factors are decisive:
- Jaw: Upper jaw, lower jaw or both jaws together,
- Implant brand: Straumann, Nobel Biocare, German implant brands or Korean-made systems (see our implant brands guide),
- Prosthesis material: Acrylic hybrid or zirconia,
- Additional procedures: Extractions, bone contouring, grafting if necessary.
All-on-4 warranty and maintenance
Implant manufacturers’ warranty terms vary by brand. The most important factors for longevity are regular check-ups, professional cleaning and good oral hygiene at home; the health of the tissues around the implants is monitored for peri-implantitis.

Frequently asked questions
Is All-on-4 painful?
The procedure is performed under local anaesthesia. Afterwards there may be swelling and tenderness for a few days, which is controlled with painkillers.
Can All-on-4 be done for a patient with bone loss?
Thanks to the angled placement of the back implants, it can be performed in many cases of bone loss without the need for a graft. The final decision is made based on the CT scan; if bone is severely insufficient, zygomatic implants or grafting options are considered.
Can diabetic patients have All-on-4?
Implant treatment can be planned for diabetic patients whose blood sugar is under control. HbA1c values and healing risk are assessed together with your dentist.
Do All-on-4 teeth come out while eating?
No. The prosthesis is screwed onto the implants; it can only be removed by the dentist for check-ups and maintenance.
