Objective：To evaluate the effect of combined surgical and orthodontic treatment in osteal bimaxillary protrusion.Method：Twenty-two patients with osteal bimaxillary protrusion were corrected by combined surgical and orthodontic treatment.Result：None of the twenty-two patients had complications such as tooth discoloration or odontonecrosis after the treatment.According to the X-rays analysis and clinical manifestation,the coordination of tooth,jaw bone and lineament was proved successful.After clinical and follow up observation,the occlusion was well and the effect was stable.Conclusion：Combined surgical and orthodontic treatment can not only guarantee soft tissues like muscles be conditioned to the new position of jaw bone,but also help construct the stable occlusion in patients with osteal bimaxillary protrusion.
