Treatment of class II malocclusions poses a major challenge for orthodontist. Class II malocclusion due to mandibular retrognathism during active growth can be treated using removable myofunctional appliances. Fixed functional appliance are given in non compliant patient. The present case report shows efficiency of Powerscope in correcting mandibular retrognathism in a patient aged 14-year-old male patient with a chief complaint of irregularly placed upper front teeth. Diagnosis revealed retrognathic mandible, orthognathic maxilla, Class II skeletal base with average towards vertical growth pattern with end on molar and canine relation on both side, crowding in upper and lower arch, overjet of 6mm, overbite of 4 mm and maxillary mid line shifted towards right side by 1mm. The case was treated initially with MBT 0.22” prescription followed by Powrerscope. Stable and successful results were obtained with improvement in facial profile, skeletal jaw relationship. Power scope proved to be effective in achieving correction by combination of skeletal and dental changes, also reduces time and helps in managing non-compliant patients.
