Background and Objectives: Among various interarch appliances for the correction of Class II malocclusion, PowerScope is one of the latest appliances used in the clinical practice of orthodontics. This clinical study was conducted to evaluate the clinical efficiency of PowerScope appliance by assessing skeletal, dentoalveolar, and soft-tissue changes and condyle-glenoid fossa relationship after using the appliance. The null hypothesis of this research is that there is a significant difference between dentoalveolar and soft-tissue changes alone. Methodology: Ten patients of age between 11 and 16 years, 4 males and 6 females, who reported to the Department of Orthodontics and Dentofacial Orthopedics, have been treated for Class II malocclusion (nonextraction) were selected for the study. Inclusion criteria included convex profile, retrognathic/deficient mandible, growing patient at least pubertal growth period, minimal crowding, and positive visual treatment objective. Exclusion criteria included patients with neuromuscular disease, temporomandibular joint problem, and skeletal open bite. Statistical Analysis: Statistical analysis is performed using Wilcoxon signed-rank test. Results: The study revealed the following findings. There are statistically significant changes in dentoalveolar and soft-tissue parameters after using PowerScope appliance. Statistical significant changes are seen in the anterior and posterior joint spaces relationship after using PowerScope appliance. Interpretation and Conclusion: Thus, PowerScope was clinically efficient in the correction of Class II malocclusion in noncompliant patients. Although there were changes in the skeletal parameters, they are not statistically significant. Hence, based on this clinical study, we can conclude that the Class II correction with PowerScope occurred almost entirely by dentoalveolar movement.
