The purpose of this study was to evaluate the treatment outcome of Twin Block functional appliance and to determine the skeletodental, soft tissue and TMJ changes concurrent with the treatment. Ten subjects 5 males and 5 females with age ranged from 9 to 11 years were used in this study. All the cases showed Angle's Class II division 1 malocclusion due to mandibular retrusion. For each case out of the ten, lateral Cephalometric x-ray, right and left tomographic X-ray were done before and after treatment. On the base of the data obtained from this study both skeletodental and soft tissue improvement were detected after treatment. Also a significant reduction of the posterior joint space with significant increase of the condylar head thickness was seen. These outcomes make the appliance very effective in cases with retrognathic mandible, orthognathic maxilla and normal incisors inclination.
