Asher Facial Bow

Recommended especially for correction in protrudence and overbite cases with extractions in sliding techniques (Straight-Wire).
Designed to fit into the loops of archwires of 38 mm, in order to avoid manipulations to the doctor.
It is used in conjuction with extraoral headgear: high-pull for upper teeth.
Can be used to retract incisors and cuspids, on block. Once the cuspids have been moved distally, it is often used to move upper incisors distally.
