Utilizing Forsus Fatigue Resistance Device for Harmonious Facial Profile in Class II Malocclusion- A Case Report

Skeletal class II malocclusion is a common orthodontic situation. Forsus is a fixed functional appliance that works really well for the treatment of class II malocclusion. It can apply a steady force, the degree of which can be changed by selecting a pushrod from various sizes to meet varied therapeutic needs. When the Forsus FRD's spring is compressed to 12 mm, a force of 226g can be applied. A case report of a 13-year-old patient, who was diagnosed in the department of orthodontics and dentofacial orthopaedics, has been described. In this case, patient had a convex facial profile and visual treatment objective was positive. Cephalometric radiograph revealed presence of skeletal class II malocclusion. Intraoral examination showed presence of Angle’s class II division 1 malocclusion. Accordingly, the innovative treatment plan was designed for extraction of over retained deciduous teeth, followed by space closure using mushroom loop (M Loop). Treatment plan also included, correction of class II division 1 malocclusion using fixed orthodontic treatment using MBT 0.022” slot prescription with forsus fatigue resistance device(FRD), establishing functional stability and esthetics, without disturbing the surrounding structures and maintaining the periodontium integrity. Case was successfully completed in 1.5 years.
