Highlights
The Class II malocclusion in growing patients is common finding in orthodontic set up
The use of intra oral class II elastics pose the same problem and have additional vertical effects which are detrimental to final outcome in most cases.[2]
ForsusTM fatigue resistant device (FRD) has a spring component that delivers the force, which when compressed maximally produces around 200gm of force that is equivalent to using heavy intraoral class II elastics.[4]
Summary
The Class II malocclusion in growing patients is common finding in orthodontic set up. Amongst the variety of components of Class II malocclusion, mandibular retrusion is most common finding.[1] Treatment approach in such cases varies from using a headgear to restrict maxillary growth, using a functional appliance or a combination of both. The use of intra oral class II elastics pose the same problem and have additional vertical effects which are detrimental to final outcome in most cases.[2]. Forsus produces more of a dento-alveolar changes as compared to skeletal changes brought about by removable functional appliances.[5,6] forsus produces more of lower incisor proclination and has less vertical side effects when compared to intraoral class II elastics.[7] The duration with forsus should be minimum 6 months to bring about necessary changes in occlusion.[8].
