Reverse Vector Arches

Increases efficiency in closing anterior open bites and correcting excessive overbites

Employs curve of spee to eliminate the need for step downs, step ups and other varieties of activating loops to

correct overbites

Leveling by extrusion (relative intrusion) can now be accomplished by one continuous reverse vector

Minimizes molar rotation

Controls incisor torque

Permanent midline etchmarks: three lines for maxillary, one line for mandibular arch
