| Abstract | ||
| Aim of the work: The present study was conducted to assess four cephalometric measurements utilized in evaluation of the maxillary position in the anteroposterior direction. The assessment was depending on normality parameters of each measurement and the correlation between them. Material and Method: Lateral cephalometric radiographs of forty Egyptian adults (20 males and 20 females) with an age range from 19-22 years were selected for this purpose. All had accepted normal occlusions, normal skeletal relationship and balanced profiles. The radiographs were traced and the following measurements were done; SNA angle, A point to nasion perpendicular distance, condylion to A point distance, and basion to A point distance. Statistical analyses were performed to asses these four measurements. Results: The results revealed that Ba-A was the best measurement satisfied the normal distribution assumption. Ba-A and SNA angle had the highest symmetrical distribution. There were significant correlation between all measurements except between Co-A and either SNA and A-Np. In addition, there were significant differences between males and females regarding Co-A and Ba-A measurements. Conclusion: In assessing the maxillary growth, Ba-A measurement satisfied the normal and symmetrical distribution assumption better than the other studied measurements. The males norms of Co-A and Ba-A measurements should not be used for females. | ||
