Abstract / Summary
Management of Class II malocclusion in late adolescents pose a therapeutic challenge due to the limited growth potential and the need to achieve balanced occlusal correction with facial aesthetics. While fixed functional appliances such as the Forsus Fatigue Resistance Device (FRD) are widely used during active growth phases, literature describing their application in growth-limited individuals is comparatively limited; particularly in patients with a horizontal growth pattern, where vertical control is critical. The present case presents a detailed description of a 19-year-old female patient with Class II malocclusion and its management by non extraction approach using Forsus FRD. Growth assessment was performed using cervical vertebral maturation indicators, confirming minimal residual growth potential. The present report focuses on treatment planning considerations, appliance selection and role of dentoalveolar camouflage in achieving functional occlusal correction, when growth modification is no longer possible. The case highlights the role of controlled biomechanics and torque management in achieving predictable dentoalveolar camouflage while minimising undesirable effects in late adolescent patient. Forsus FRD was delivered after alignment and levelling on a rigid stainless steel archwire with emphasis on incisor torque control. Active Forsus therapy was carried out for seven months, contributing in correction of molar and canine relationships and reduction in overjet. The total treatment duration was 24 months. Post-treatment results demonstrated achievement of bilateral Class I molar and canine relationships, improved facial profile, and satisfactory occlusal stability. Follow-up at six months showed stable results. The present case report addresses the limited evidence on the use of Forsus FRD in late adolescents with minimal growth potential and horizontal growth pattern.
