[Evaluation of morphology of incisor section of the upper jaw using cone beam computed tomography in Mongolians]

High precise evaluation of the premaxilla morphology is essential to perform detailed diagnosis and treatment plans in implantology and the orthodontic field. We aimed to study morphometric analysis measurements of the premaxilla.

In this cross-sectional study, maxillary CBCT images from 208 patients were evaluated in the Maxillofacial Radiology department between 2014-2024. Sagittal views were assessed to determine thickness of the anterior part in three levels. The difference in canal diameter and length between genders was evaluated using an One Way ANOVA test.

When determining the thickness of the alveolar ridge of the anterior part of the maxillary bone in the sagittal plane at the upper level, it was 11.00±1.65 mm in men and 10/70±1.78 mm in women (f=0.32), (p=0.811), at the lower level 5.62±0.97 mm in men and 5.35±0.78 mm in women (f=0.54), (p=0.66) and an average level of 6.05±141 mm in men and 5.70±1.18 mm in women (f=0.29), (p=0.83), respectively, statistically significant no gender difference was observed.

The average superior thickness of the maxillary anterior bone was 10.85±1.71 mm, the medium thickness was 5.87±1.29 mm, the inferior thickness was 5.48±0.87 mm, among Mongolian adults. We observed that the maxillary anterior bone thickness is increased from tip to base of the them.
