Sponsor's own description
The treatment of skeletal Class II malocclusion can be carried out through different approaches. One of these is the using of Fixed Functional Appliances (FFA), one of main drawbacks of these appliances is the proclination of the lower anterior teeth limiting the skeletal effect that is originally addressed in those patients.To overcome these limitations, miniplates anchored Forsus FRD were introduced, it showed high success rate in achieving a more skeletal effect with retroclination of lower anterior teeth rather than their proclination. Although Herbst appliance is categorized as the best FFA with more stable skeletal and dentoalveolar effects, miniplates had never been tried as an anchorage source with Herbst appliance in skeletal Class II patients.
