Treatment effects of fixed functional appliance Powerscope in patients with class II malocclusion

Abstract

Introduction: Fixed functional appliances are devices which are fixed and effective 24 hours a day with minimal patient compliance which is a major advantage of fixed functional appliance. PowerScope is the latest innovation in Class II Correction which is a direct derivative of the Herbst Type II appliance. Material and Methods: 10 Patients with Class II Malocclusion Who Required Orthodontic Treatment were selected from the department of orthodontics and dentofacial orthopaedics, Al-Ameen Dental College and Hospital, Vijaypura for the study. Lateral cephalograms prior to the commencement of the treatment were recorded of 10 patients. Further, lateral cephelograms were taken prior to placement and after removal of PowerScope. The cephalograms were compared on Set of 33 cephalometric parameter divided into sagittal, vertical and angular measurements followed by statistical analysis with matched paired T test to determine the significance Result: In this study, mean and standard deviation of all the cephalometric values for before placing the powerscope and after removal of powerscope were compared out of all the 33 set of cephalometric Values, sagittal parameter Olp- Pg was statistically highly significant with p=<0.0001 show the position of mandibular base (Olp-Pg) came forward. Molar relation was statistically highly significant showing correction from class II to class I molar relation. Angular parameter ANB was statistically significant with p=0.001 shows skeletal mandibular advancement in relation to maxilla. Conclusion: PowerScope could be one of the best treatment options for class II correction, especially in noncompliant patients with a drastic improvement in soft tissue profile and aesthetic appearance.
