Soft tissue cephalometric changes after correction of skeletal class II with Twin block functional appliance therapy: A pilot study

Abstract

Background: The correction of skeletal class II malocclusions when the patient is in growing stages by functional appliances is most favorable option, since a normal path of mandibular growth can be achieved at this stage. This article aims at determining the effects of Twin block functional appliance on the facial soft tissues. Materials and Methods: Changes in soft tissue after the correction of skeletal class II with Twin block were measured using lateral cephalometric radiographs. Results: Significant soft tissue changes have been found after treatment with Twin block functional appliance. Conclusion: Twin block functional appliance in skeletal class II patients with retrognathic mandible is also capable of producing significant and favorable soft tissue changes in addition to its skeletal and dental effects.
