Treatment of class ii in adulthood by forsus frd device.

Objectives: Scientific research data show that the Forsus FRD seems to have a great potential in the correction of Class II in childhood. The conclusions reached by the various Authors seem to support the hypothesis of an exclusively or mainly dentoalveolar correction, as the skeletal correction seems to have no - or little - appreciable results. In the light of such provided by different Authors, the potential of dentoalveolar compensation in adult patients with mild skeletal class II was investigated.

Materials and methods: At the UOC (Complex Operative Unit) of Orthodontics at "G. Eastman" Hospital Rome, 3 cases of skeletal class II mild (ANB <5 °) in adult patients were selected. They were treated with fixed multibracket appliance and Forsus EZ2 module. Cephalometric tracings were compared at the beginning and at the end of the treatment in order to assess the skeletal and dentoalveolar changes.

Results: The occlusal correction was achieved through a dentoalveolar compensation characterized by the flaring of the lower teeth.

Conclusions: Forsus FRD equipment is an excellent compromise for the correction of mild Class II, even during the post development age. The resulting correction is appreciated at dental alveolar level with a mesial movement of the incisors and molars.
