    Comparison of the effects of fixed and removable functional appliances on the skeletal and dentoalveolar structures.
    (2011) Bilgiç F.; Hamamci O.; Başaran G.
    To compare and analyse the effects of activator and Forsus FRD EZ appliances in the treatment of skeletal Class II division I malocclusion. Lateral cephalograms and hand-wrist radiographs were collected from 24 Class II division I growing patients (14 females, 10 males). The patients were randomly divided into two equal groups and either treated with an activator appliance (Mean age 12.67 +/- 1.24 years) or with a Forsus FRD EZ appliance (Mean age 12.31 +/- 1.09 years). Pretreatment and posttreatment cephalometric radiographs were obtained, traced, superimposed and data analysed using paired t-tests and the Wilcoxon signed rank test. The results demonstrated that the Forsus FRD EZ effectively corrected the Class II malocclusion, but the changes were mainly dentoalveolar. The Forsus FRD EZ appliance induced a clockwise rotation of the occlusal plane without significant alteration in the vertical facial dimension. Skeletally, maxillary growth was restricted and pogonion moved forward which improved the profile. The Forsus FRD EZ appliance may be an effective dentoalveolar treatment method to manage a skeletal imbalance and improve the profile in growing patients.

    Noncompliance therapy: Veltri appliance.
    (2009) Doğan K.; Başaran G.; Hamamci N.; Hamamci O.
    To achieve intraoral molar distalization without any extraoral appliance or patient cooperation. The intraoral distalization technique was performed on a female 12 years 8 months of age with cooperation deficiency, and the positive results are presented. The patient initially accepted the headgear planned at the beginning of treatment, but she did not wear it long enough. We therefore abandoned the use of extraoral appliances and employed intraoral distalization instead. We preferred to use a Nance button Veltri appliance we could create in our clinic. Once the patient had accepted our new treatment plan, we completed the distalization process in about 2 months. After a 2-month retention period, we completed treatment with a fixed Roth edgewise appliance and maximum anchorage in the maxilla for approximately 18 months. Following treatment, a Class II Division I dental relationship became a Class I relationship in both the canine and molar regions, and a functional occlusal relationship and esthetic facial appearance were obtained. This appliance can be used when patient cooperation is compromised. COPYRIGHT © 2008 BY QUINTESSENCE PUBLISHING CO, INC.
