摘要

The device (1) has a rear head (2) for fixing to a molar (M), and front head (3) for attachment to a canine tooth (C) in front of the molar. An intermediate assembly couples the rear head and the front head to each other. A hook (14) attaches a return device (30) for returning the orthodontic device rearwardly. The intermediate assembly includes an anteroposterior arm (20), a rear hinge (21) linking the arm to the rear head, and a ball joint (22) linking the anteroposterior arm to the front head.
