Objective: This study aimed to assess the skeletal and dento-alveolar changes associated with using the new hybrid aesthetic functional appliance in the correction of class II division 1 malocclusion. Materials and Methods: Sixteen patients aged (8-12y) who had skeletal class II division 1 caused by mandibular deficiency were chosen and treated with the hybrid aesthetic function appliance. Before and after treatment, lateral cephalometric radiographs, photographs and study casts were taken. The duration of treatment was about 9-12 months. Results: The hybrid aesthetic functional appliance improved the mandibular forward position (P = 0.005) and increased the mandibular effective length (P = 0.001) so increasing the difference between the mandible and maxilla effective lengths (P ≤ 0.001) but the appliance also flared the lower incisors (P ≤ 0.001). Conclusions: Skeletal class II division 1 malocclusion was effectively corrected with the hybrid aesthetic functional appliance. Hybrid aesthetic functional appliances produced skeletal effects by increasing the mandibular length and forward growth of the mandible. Also, the appliance produces a dental effect represented in the flaring of lower incisors.
