[Biomechanics of lower molar mesialization on mini-screws in multi-vestibular technique].

Introduction: Molar protraction can be used in several clinical situations. It provides a real service to the patient, when it makes it possible to replace an implant, for example, or in case of a very damaged molar compared to the patient’s age.

Material And Method: In this article, the authors describe the different molar mesialization systems in the vestibular multi-attachment technique, outlining the biomechanics of each.

[Mini-implants: pushing the limits of traditional orthodontics].

With the introduction during the last years of new tools such as low friction braces, skeletal anchorage, and especially mini screws, the tremendous evolution of lingual orthodontics, orthodontic care has evolved at a rhythm never known before. Using various clinical examples, the author shows the tremendous impact of the use of mini screws in a great number of treatments, producing particularly favourable facial changes, often going beyond the usual limits of orthodontic treatments.
