Management of facial asymmetry poses as a challenge to many orthodontists due to the topographic intricacies of the various facial structures. Traditional manual model of surgery, though an essential aid to treatment planning can be time consuming, complicated and may leave place for potential errors. Stereolithographic model using three- dimensional approach is a revolutionary change in the field of facial asymmetry management. The aim of this study was to use stereolithographic model for orthognathic-surgical treatment of a patient with facial asymmetry having class III skeletal base. A 14-year oldfemale patient presented with a class III skeletal base with hemi mandibular elongation. Stereographic models were designed from the CT scan of each patient. The images were reformatted into three- dimensional plane using these models. Extraction of impacted third molars in the osteotomy site followed by extraction of upper first premolars were planned for the orthodontic part of the treatment. Le forte I maxillary impaction of 4 mm with jaw correction and Bilateral sagittal split osteotomy setback of 5 mm was planned for the surgical part in the virtual surgical wafer. The jaw procedures were performed in accordance with the virtual plan. A 5-year follow-up showed remarkable improvement in the facial asymmetry of the patient with stable occlusion. This complicated case therefore highlights the advantages of rapid prototyping using CT images for the production of stereolithographic models for a better and more precise correction of facial asymmetries.
