In contemporary orthodontics, the complex and multifactorial etiology of class II malocclusion has always presented a clinical challenge to the orthodontists. Management of class II malocclusion requires a thorough evaluation as the treatment options available vary widely from growth modification using dentofacial orthopedics with functional appliances, dental camouflage using extraction or non-extraction approaches or even orthognathic surgery. Selection of treatment modality for class II patient is based on the age, growth potential, location of skeletal component, the severity of malocclusion and the compliance of the patient. Correction of skeletal class II malocclusion due to retrognathic mandible can be
done with non-compliance appliances such as fixed functional appliances. Fixed functional appliances are emerging as viable and successful treatment option for class II patients owing to the refinement in their designs and mechanics to advance the retrognathic mandible. A wide variety of non-compliance fixed functional appliances are available that can be used with comprehensive fixed mechanotherapy. Forsus fatigue resistant device and Powerscope are two such fixed functional appliances used for class II correction. These appliances can be assembled chair-side and installed easily intraorally. This case report substantiates the efficacy of these appliances in the two types of Class II malocclusion growing patients presenting with a chief complaint of forwardly placed upper jaw and a mean age of 14 years (age range of 13–15 years).
