i-TTЯ Lingual System - Lingual Orthodontics theoretical and practical course

Bari, Centri Odontoiatrici Specialistici

7 - 8 - 9 November 2014

Presentation of the course

Till a few years ago lingual orthodontics was considered just an alternative to buccal orthodontics and only for esthetic problems, requested from particular patients, who desired, because of personal needs, a beautiful smile without compromising their own dental esthetics. Than, thanks to a lot of studies all over the world on lingual orthodontics and more and more innovative materials, less invasive too, this technique arised close to buccal orthodontics not only as a simple alternative but like a valid orthodontic technique able to solve the great part of dento-skeletal malocclusions.

The bracket i-TTЯ produced by Rocky Mountain Orthdontics company®, from an idea and project of Prof. Aldo Macchi, is an innovative lingual bracket. This lingual bracket presents characteristics completely different from other lingual brackets both as regards the application, both the insertion of the archwire and the control of the dental movements. The i-TTЯ is a not Edgewise lingual bracket, with dynamic torque and selective friction control.
