Preparazione ortodontica per il trattamento delle II Classi da retrusione mandibolare.

This research aims to introduce a therapeutic protocol for patients with Class II skeletal malocclusion caused by mandibular retrusion. The Authors emphasize the benefits of orthodontic therapy in removing dental interferences before using a functional appliance. Especially in Class II skeletal malocclusions with madibular retrusion, the aim of the first part of orthodontic treatment should be the correction of occlusal relationships interfering with the development of the disc-condylar complex. It is therefore necessary that orthodontic therapy remove trasversal and vertical premature contacts altering mandibular position. Furthermore this preliminary correction allows the establishment of a more favourable environment that will improve the result of functional therapy.
