Ni-Ti Springs - Closed Coil
Cuspid Retraction — Eyelets are hooked on a free-sliding crimp hook placed mesial to the cuspid or on a Hemi-Hook of the cuspid bracket. If desired, a crimpable stop can be placed on the archwire to control the amount of retraction. Distalizing Molars/Anterior Unraveling — Crimpable sliding hook used as tie-back is placed distal to the lateral incisor. Eyelets are hooked onto the crimp hook and first molar buccal tube hook to activate retraction.
