A severe skeletal Class II correction by activator headgear

The present case signifies the importance of functional jaw orthopedic treatment in a vertically growing female patient with mandibular deficiency and maxillary vertical excess and superimposition of pretreatment and posttreatment cephalometric tracings shows desired treatment outcomes. Skeletal Class II malocclusion with mandibular deficiency and maxillary excess is a severe skeletal problem encountered in growing individuals. Correction of mandibular deficiency and maxillary excess in a skeletal Class II patient with a vertical growth pattern poses a great challenge. The control of vertical dimension becomes very important as downward and backward rotation of mandible will exaggerate the facial convexity. The present case signifies the importance of functional jaw orthopedic treatment in a vertically growing female patient with mandibular deficiency and maxillary vertical excess. Activator headgear combination was used for skeletal correction which was followed by fixed mechanotherapy. Superimposition of pretreatment and posttreatment cephalometric tracings shows desired treatment outcomes.
