How Many Implants Are Needed for Full Mouth Restoration?
The number of implants required varies based on the type of restoration. Here is a guide.
The number of implants needed depends on several factors, including bone quality, jaw size, and the type of restoration.
- For the upper jaw (maxilla):
- Overdenture (removable): 4β6 implants
- All-on-4: 4 implants
- All-on-6: 6 implants
- Individual implants: 8β10 implants (one per missing tooth)
- For the lower jaw (mandible):
- Overdenture (removable): 2β4 implants (the lower jaw can often manage with fewer)
- All-on-4: 4 implants
- All-on-6: 6 implants
- Individual implants: 8β10 implants
- Why different numbers?
- 4 implants (All-on-4) β uses two straight implants in the front and two angled implants in the back to maximize contact with available bone. This often avoids the need for bone grafting
- 6 implants (All-on-6) β provides more support and is better for people with good bone density who want extra stability
- Overdentures with 2β4 implants β sufficient to hold a removable denture securely, especially in the lower jaw
What Your Dentist Will Consider
- Bone density and volume
- Jaw size and shape
- Bite forces
- Your budget
- Whether you prefer fixed or removable
