The relation of the maxillary central incisor, nasal bone, anterior cranial base lengths and the body height in different skeletal patterns

Abstract EN

Background : The reason for measuring the frontonasal field which include the length of the anterior cranial base, the nasal bone, and the incisors is that all these structures deviate from normal structures in patients with malformations of the frontonasal field.

Materials and Methods : Maxillary central incisor, nasal bone and anterior cranial base lengths were measured by Cephalometric analysis of 122 lateral Cephalometric radiographs using AutoCAD 2008 program, also body height was assessed by height measuring standard for adult patients with different skeletal patterns, including CLI (n= 48), CLII (n= 45), CLIII (n= 29), normal MP-SN angle (n= 70), low angle (n= 28) and high angle (n= 24) .

Results and Conclusion : The maxillary central incisor was longer in high angle males group c.

Short nasal bone was found in CLII males and females and in low angle males group.

Longer anterior cranial base was found in low angle males, while the anterior cranial base was shorter in high angle males.
