Cephalomteric changes in airway dimensions with twin block therapy in growing Class II patients
Introduction: Myofunctional appliances are commonly used for correction of skeletal Class II malrelationship. These appliances influence craniofacial and nasopharyngeal dimensions. Objectives: The present study was done to evaluate changes in airway with twin block therapy. Materials and Methods: Ce...

| description | Introduction: Myofunctional appliances are commonly used for correction of skeletal Class II malrelationship. These appliances influence craniofacial and nasopharyngeal dimensions. Objectives: The present study was done to evaluate changes in airway with twin block therapy. Materials and Methods: Cephalometric assessment of airway was done in 25 growing children in the age group of 11-13 years with Class II skeletal pattern. All the patients were treated with twin block appliance. Pre and post treatment lateral cephalograms were taken to evaluate the changes in different airway and craniofacial dimensions during the treatment period. The average treatment duration was 14.5 months. Results: Airway: A significant increase was observed in upper and lower pharyngeal width and area of bony nasopharynx. Craniofacial dimension: There was a significant increase in effective mandibular length, ramal length and mandibular plane angle. There was an increase in SNB angle, which resulted in decreased ANB angle. Conclusion: There was a definite improvement in airway dimension following twin block therapy |
