Title: Lingual Liberty: a philosophy,  a technique

The Lingual Liberty  system has been conceived to offer to the users a maximum of  liberty,  control of the set-up, choice of brackets and wires, immediate   in-office rebonding, lab independance  and a maximum of accuracy due to a specific bracket positioning procedure.

Lingual Liberty does not need robot for bending wires, even during detailing sequence,  because the lingual liberty  wires are flat, straight and preformed.

The presentation of cases will demonstrate the simplicity and the efficiency of the clinical procedures.
