Introduction: Angle’s Class II Div 1 malocclusion is one of the most common malocclusions in orthodontics. In cases of Angle’s Class II Div 1 malocclusion with mandibular deficiency, myofunctional appliances are often used with the intent of stimulating mandibular growth. Twin block is one of the most popular myofunctional appliances.
Aim: The aim of this study was to find out “Does the length of mandible increase with Twin Block appliances” using cephalometric radiograph.
Materials and Methods: Cephalometric radiographs of 15 patients who had Class II Div I malocclusion, before and after treatment were examined. The mean changes after Twin Block were compared with pre-treatment parameters using independent‘t’ test.
Results: There were statistically significant differences in Pre and Post-treatment mandibular length. Patients treated with twin block appliance showed a mean increase of 4 mm in the mandibular length.
Conclusion: Twin Block is an effective myofunctional appliance which can be used to increase the effective mandibular length in patients with skeletal Class II Div I malocclusion.
Keywords: Functional appliance, Class II malocclusion, Twin block
