Objectives: to evaluate PowerScope appliance assisted with Low-Level Laser Therapy on mandibular changes in the treatment of skeletal class 2 malocclusions.
Patients and methods: The current study was conducted on 24 orthodontic female patients with an age range from 14- to 16-year-old who were collected from the outpatient clinic at Orthodontic Department, Faculty of Dental Medicine, Boys, Al-Azhar University, Cairo, Egypt. They were randomly divided into 2 groups, each consisted of 12 patients, Group A (Laser group) were treated with PowerScope appliance and Low-Level Laser Therapy (LLLT), Group B (Control group) were treated with PowerScope only.
Results: There were a statistically significant changes in skeletal and dentoalveolar measurements.
Conclusion: PowerScope appliance provides an effective tool for the treatment of Class II division 1 malocclusion in adolescent patients. The PowerScope appliance promotes restriction of anterior maxillary displacement with significant forward mandibular repositioning which reduces skeletal convexity. Effects of PowerScope appliance with or without LLLT were mainly dentoalveolar with little skeletal effects
