Fixed functional appliances for correction of Class II malocclusion: A review

This review article presents various fixed functional appliances that have been developed all these years with the aim of correcting Class II malocclusion. Class II malocclusion though multifactorial in etiology, but the main cause is mandibular retrognathia. The treatment aims to modify the direction and amount of mandibular growth rather than restricting the development of the maxilla. Hence, the various appliances were developed removable and fixed with the aim to correct Class II malocclusion. Fixed functional appliances were developed with the aim to correct Class II malocclusion without the need of patient compliance, which was a major concern toward removable functional appliances.
