THE HORIZONTAL
678-802 The Horizontal instrument produces an indentation to accent individual root torque. It also serves a second purpose by enhancing retention of either clear aligners or retainers by placing an indent into a tooth’s undercut or below a bonded attachment to enhance the contact of the aligner to that attachment.
Accent individual root torque by producing an indent at the gingival margin on either the buccal or lingual for any tooth in the arch form.
