Antegonial Notch和Ramus Notch的深度與下顎旋轉的相關性
Evaluation the Relationship of the Depth of Antegonial Notch and Ramus Notch with Rotation of Mandibule
摘要
In recent years, some researchers have reported that the depth of the mandibular antegonial notch is related with mandibular rotation and higher the lower facial height. However, the data for those studies were derived from populations with extreme morphologic characteristics. The purpose of this investigation was to evaluate whether the depth of antegonial notch and ramus notch are related to the mandibular rotation. Lateral cephalometric radiographs were obtained from 30 males and 30 females with cervical vertebral maturation (CVM) at 5 and 6 stage. Correlation analysis revealed that the depth of antegonial notch and ramus notch both with SN-GoGn, SN-Palatal, Palatal-GoGn and Gonial angle not are connected (P＞0.05), with Y-axis angle related (P＜0.05), the male has deeper antegonial notch than female, but the ramus notch depth does not have the difference in the male and female groups. We concluded that the depth of antegonial notch and ramus notch fails to provide sufficient indication of mandibular rotation.
