Objectives:The objective of the study is to assess the skeletal, dental, and soft-tissue effects of PowerScope fixed functional appliance in Class II malocclusion. Materials and Methods: Fifteen late adolescent Class II subjects (CVMI Stages 5 and 6) were treated with fixed mechanotherapy and PowerScope fixed functional appliance. Student t-test was used to compare the cephalometric changes produced before insertion of appliance (T1) and 6 months after the treatment with this appliance (T2). Results: Maxillomandibular relationship improved with significant lengthening of the mandible. There was retroclination of maxillary incisors, proclination of mandibular incisors, extrusion, and sagittal displacement of mandibular molars and clockwise rotation of occlusal plane. Conclusion: PowerScope is effective in correcting Class II malocclusion with a combination of dentoalveolar (primarily) and skeletal changes. abstRactThis is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 License, which allows others to remix, tweak, and build upon the work non-commercially, as long as appropriate credit is given and the new creations are licensed under the identical terms.
