All-on-4: fixed teeth, supported by implants.
All-on-4, also called a full arch fixed prosthesis or fixed denture, is a complete set of teeth supported by implants placed in the jawbone. At Well Clinic Odontologia in São Paulo, the case is planned digitally and the prosthesis is produced at the Well Lab, the clinic's own laboratory, with the possibility of an immediate prosthesis assessed case by case.
Consultations are available in English and Portuguese, in Jardim Paulista, São Paulo.
Made at the Well Lab
The full arch, planned before the first incision.
Rehabilitating an arch is not only about placing teeth where they are missing: it is about restoring how you bite, chew, speak, and breathe. This is a team case, and the team plans together.
A 2-hour first consultation
The team evaluates the whole case: bone condition, bite, general health, and the habits that influence how implants heal.
3D CT scan and DSD
Your new smile is designed digitally over your own face and the case is planned virtually, with the result visible before anything begins.
Guided implant surgery
The implants that will support the prosthesis are placed using a printed surgical guide. Whether an immediate prosthesis is possible is decided during planning, case by case.
Prosthesis made at the Well Lab
The definitive full arch prosthesis is produced in the clinic's own laboratory, in a CAD/CAM workflow, designed around facial harmony and biomechanics.
Fixed full arch or a conventional denture?
All-on-4 (fixed full arch)
- A fixed prosthesis, supported by implants placed in the bone
- It does not come out day to day: only the dentist removes it
- A full arch planned digitally for your face
Conventional denture
- A removable prosthesis, resting on the gum
- You take it in and out for cleaning
- It can shift while you speak or chew
The same treatment travels under several names: All-on-4, full arch protocol, fixed denture, implant supported denture. They all describe a fixed full arch prosthesis supported by implants. Which option makes sense for you is a planning decision, made with the team after your evaluation.
Understand the pieces of the treatment.
- Dental implants: the foundation of the protocol, titanium posts placed in the bone
- Digital Smile Design: how the new smile is designed before anything starts
- Sedation dentistry: an option for patients who are anxious about surgery
What patients ask us.
Is All-on-4 the same as a fixed denture?
Yes. All-on-4, full arch protocol, and fixed denture are different names for the same idea: a complete fixed set of teeth supported by implants, rather than a removable prosthesis resting on the gum.
Will I leave with teeth on the same day?
The possibility of an immediate prosthesis is assessed case by case during planning, and depends on bone condition and the surgical plan. It is defined before surgery, not improvised on the day.
Can I do this if I am travelling to Brazil for treatment?
The evaluation can start online, and records such as scans and images can be reviewed before you arrive. The team then organizes the appointments around your time in São Paulo. Because the prosthesis is produced at the Well Lab inside the clinic, adjustments happen on site.
How much does All-on-4 cost in São Paulo?
The investment depends on your individual plan, defined after the 2-hour first consultation, and it changes with the number of implants, the type of prosthesis, and the condition of the bone. The complete plan is presented before any decision.
