Is PowerScope™ 2 an effective Class II corrector ? A prospective cephalometric study

Abstract

Objectives: The study was carried out to evaluate skeletal, dental and soft tissue effects produced by PowerScope™ 2 appliance following the correction of skeletal Class II malocclusion. Materials and Methods: A total of 10 patients (3 males and 7 females with mean age of 14.40 ± 0.70 yrs) diagnosed with skeletal Class II malocclusion and indicated for fixed functional appliance were treated using Power Scope™ 2 appliance. Paired t-test was used to assess skeletal, dental and soft tissue changes evaluated on lateral cephalograms taken at pre-functional (T1) and post-functional (T2) stages. Results: Maxillomandibular sagittal relation was markedly improved with a significant gain in the length of the mandible along with a restraining effect on the maxillary dentition. The improvement in molar relation was mainly contributed by dentoalveolar effects (72.3 %) and secondarily by skeletal effects (27.7 %) while the reduction in overjet was contributed by 22.4% skeletal and 77.6% dental effects. Vertical changes were non-significant. Following PowerScope™ 2 therapy there was an overall improvement in facial esthetics. Conclusion: Power Scope™ 2 serves as an effective skeletal Class II corrector with primarily dentoalveolar and secondary skeletal effects.
