Number of implants |
2 to 6 implants |
3 implants or
more |
Female part |
Clips and retention devices (plastic or brass) |
- counterbar and retention devices (plastic or brass) |
Type of prosthesis |
Removable prosthesis with mucosal support |

Mechanical behaviour
|
- tissue duality
- rotation around the CB if 2 implants
|
- 0 degré of liberty
- no tissue duality
- behaves like a fixed implant-retained overdenture
- behaves like a fixed implant-supported prosthesis
