All-on-4 dental implants are a fixed full-arch tooth replacement solution designed for patients who have lost most or all of their teeth. This method allows a complete set of teeth to be supported by four strategically placed implants.
This guide explains the All-on-4 concept, procedure steps, recovery, and important considerations.
What is the All-on-4 treatment?
All-on-4 is a dental implant technique where four implants are placed in the jawbone to support a full arch fixed prosthesis. The implants are positioned at specific angles to maximize bone support and stability.
In some cases, a temporary fixed prosthesis can be placed on the same day.
Who is a suitable candidate?
All-on-4 may be suitable for patients who:
- Have lost most or all teeth in one or both jaws
- Have sufficient bone density or moderate bone loss
- Wish to avoid removable dentures
- Are in good general health
A detailed clinical and radiological assessment is required.
How is the procedure performed?
Before the procedure
- Comprehensive examination and imaging (CBCT)
- Digital treatment planning
- Medical history evaluation
During the procedure
- Local anesthesia or sedation is administered
- Four implants are placed in the jawbone
- A temporary fixed prosthesis may be attached on the same day
After the procedure
- Healing and osseointegration period begins
- Follow-up visits are scheduled
- Final prosthesis is placed after healing
Treatment timeline
- Surgery and temporary teeth: 1 day
- Healing period: 3–6 months
- Final prosthesis placement: after healing
Timelines may vary depending on bone condition and individual healing.
Recovery & aftercare
- Swelling and discomfort may occur in the first days
- Soft diet is recommended during initial healing
- Smoking should be avoided
- Excellent oral hygiene is essential
Possible risks & considerations
- Swelling or bruising
- Implant failure (rare)
- Temporary speech adaptation
- Need for additional procedures in some cases
These risks are minimized with proper planning and aftercare.
Expected results
- Fixed, non-removable teeth
- Improved chewing and speech
- Enhanced facial support
- Long-term functional solution
