Derotation- and Molar Correction Spring
The Derotation Spring is used to derotate canines and pre-molars. Using
the partial arch technique you can derotate teeth during the levelling
phase without compromise.
Molar Correction Spring
The Molar Correction Spring has been designed to derotate and up-right
second molars by using physiologically correct force levels and
avoidance of a bite raising effect.
