ABSTRACT
Objective:To study the craniofacial characters of non-surgical treatment of the female patients with bimaxillary protrusion in northeastern region of China.Methods:80 patients with bimaxillary protrusion in northeastern region of China received orthodontic treatment were divided into two groups,the ANB angles of the first group were no more than 4.7?,the second one exceeds 4.7?.Cephalograms were analyzed in all the subjects.Compared with the normals in Beijing.Results: Most of the female patients with bimaxillary protrusion had shorter anterior cranial bases,longer posterior cranial bases,longer and more prognathic maxillas,longer mandible lengths,higher anterior and anterior upper facial heights,obvious procumbency,thicker mental thickness,procumbent soft tissue profile with a low lip line.Different groups had the features as follows:the main abnormal factors were the maxilla in sagittal aspect of the first group.They had the suitable facial planes.The second group's abnormal factors were the mandible,they had the divergent facial plane.Conclusion:The non-surgical treatment′s patients of bimaxillary protrusion have unique character.The results suggest it is of critical importance to adjust the position of jaws to benefit the improvement of facial features.
