G.20-G.21-G.23 Attachments

rigid attachments


The extracoronal dental attachment international Grifo, is available in three different versions:
- G. 20 SUPER MICRO
- G.21 MICRO
- G.23 STANDARD
is widely used and is intended to retain the removable denture to the remaining teeth.
It also allows you to solve any problem of space.
Easy to apply, it is made up of four main elements (female, male, pin and sheath) easily interchangeable removing the pin placed laterally to the sheath.
The particular cylindrical shape of the joint offers an extended contact surface giving a greater retention force and friction and gives a special ease of insertion.
Modern technology, using highly qualified materials, grants the best retention of the attachment over time.

Grifo attachments G.20-G.21-G.23 can be provided also with adjustable patrix allowing a more precise activation.
