- Gaining space with crowded front teeth
- Gap opening in the posterior region
- Rotation of teeth

- Mesializing the anterior posterior teeth
- Distalizing posterior teeth
Sizes
Six different lengths allow space to be gained from the individual tooth area to the canine-canine distance. Different colors are assigned to the individual sizes. With full compression approx. 200 cN force development (progressively decreasing).
