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.
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.
The occlusal correction was achieved through a dentoalveolar compensation characterized by the flaring of the lower teeth.
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.
科研数据表明，Forsus FRD在矫治儿童安氏II类错颌方面似乎具有巨大潜力。不同作者得出的结论似乎支持仅通过或主要通过牙-牙槽骨矫治的假说，因为骨骼矫治似乎没有或仅有不明显的效果。鉴于不同作者提供的此类信息，本研究调查了轻度骨骼型安氏II类成年患者的牙-牙槽骨代偿潜力。
在罗马“G. 伊斯曼”医院正畸综合手术单元（UOC），选取了3例成年骨骼型轻度安氏II类错颌患者（ANB<5°）。采用固定多托槽矫治器和Forsus EZ2模块进行治疗。在治疗开始和结束时进行头影测量描记，以评估骨骼和牙-牙槽骨的变化。
通过以下颌牙唇倾为特征的牙-牙槽骨代偿实现了咬合矫治。
Forsus FRD矫治器是矫治轻度安氏II类错颌的理想折衷方案，即使在生长发育后期也是如此。在牙槽骨水平，通过切牙和磨牙的近中移动实现了令人满意的矫治效果。
