No Friction Mechanics for Extraction Cases

I began practicing lingual orthodontics 40 years ago for purely aesthetic reasons, and since then I have never stopped looking for solutions to the problems posed by the lingual technique in order to enhance the quality of my treatments.

Today, I am  presenting a frictionless mechanics for extractions cases which, combined with fully digital bracket positioning, allows good control of incisor torque and avoids the usual side effects. All treatment steps will be detailed and justified during the presentation of numerous treated cases.
