Abstract

Objectives: This study was conducted to evaluate the efficacy of Powerscope appliance in the treatment of skeletal Class II patients by three-dimensional image.
Patients and methods: This study was conducted on 14 orthodontic patients with a mean age of 15.39 ± 1.25 years old. The study included post-pubertal female patients with skeletal Class 2 of ANB angle greater than 4° due to the retruded mandible. Cone-beam computed tomography was made before (T1) and after (T2) installation of the Powerscope appliance. The images were imported into Invivo dental software version 5.2 for the measurements. The collected data were tabulated and statically analyzed using Statistical Package for the Social Sciences (SPSS) version 23. Paired t-test was used to study the changes after treatment. The significance level was set at ≤ 0.05.
Results: Results showed statistically significant changes regarding skeletal and dental parameters.
Conclusion: (1) Powerscope appliance provides an effective tool for the treatment of skeletal Class 2 adolescent patients. (2) Effects of Powerscope appliance were mainly dental with lesser skeletal effects. (3) The skeletal changes were seen in the mandibular base with minimal maxillary skeletal effects.
