[Comparative study of mandibular growth and rotation in two sample groups treated according to the "Distal Active...

The "Distal Active Concept" therapy, favours an immediate repositioning of the mandible and introduces new therapeutic sequences which allow an easy correction of the Class II molar relationship, enhancing the mandibular growth simultaneously. The "Distal Active Concept" therapy is a combined treatment which induces the correction of the Class II malocclusion without extractions and without headgear. The dento-alveolar unit is used as a functional matrix to free, then enhance the mandibular growth and induce its counter-clockwise rotation. 35 patients treated with the "Distal Active Concept" therapy are compared to 33 patients, treated with the extraction of four bicuspids and in Edgewise therapy, in order to visualize the mandibular growth and the counterbalancing rotation described by Dibbets.
