The special expansion screw with a feature against unwanted reversing.
All Variety expansion screws are available with the patented unwanted reversing click feature:
- Variety click Mini – 8
- Variety click SP (small palate) Mini – 8
- Variety click Maxi – 12
- Variety click SP (small palate) Maxi – 12
The unwanted reversing click is the ideal screw locking feature during the active treatment phase: it enables reliable activation/deactivation of the screw with a clearly perceptible click after a quarter turn. For both the orthodontist and the patient, this means a high degree of security.
Both the Variety click Mini and the Variety click Maxi are primarily designed for fixed appliances in the mandible, but they can be used for early palatal expansion in the maxilla as well.
