| Objective: This study was designed to evaluate the treatment outcomes for Class II malocclusion by using PowerScope Appliance. Patients, materials and methods: A sample of 10 patients with an age range from 14 to 18 years, suffering from skeletal Class 2 and Angle Class II division 1 malocclusion. All patients didn’t undergo any orthodontic treatment previously and were free of systemic diseases that affect craniofacial growth. Pre and post‑treatment lateral cephalograms were obtained, cephalometric analysis was performed. Class I relation were obtained in with a substantial improvement in facial profile, skeletal jaw relationship, and overall esthetic appearance of the patient. A significant forward displacement of the mandible was the principal element for successful correction of Class II malocclusion. Results: Restriction of maxillary growth with significant mandibular growth were observed with Power- Scope appliance. The Class II correction was obtained mainly by slight maxillary molar distalization and intrusion, in addition to mesial migration of the mandibular molars and flaring of the lower incisors. Soft tissue profile improvements was observed with this appliance. Conclusions: PowerScope appliance provides an effective correction of Class II division 1 malocclusion in adolescent patients as it promotes restriction of anterior maxillary displacement with significant forward mandibular repositioning which reduces both skeletal and soft tissue profile convexities. PowerScope appliance caused dentoalveolar changes including slight maxillary molar distalization, in addition to mesialization of the lower molars and proclination of the lower incisors which results in correction of Class II malocclusion. | ||||
