Abstract

Objectives: Dentofacial morphology of Class III malocclusion may display a midfacial

discrepancy which requires multidirectional correction. The vomer bone as a central

strut of midface complex has a role in sustaining a balanced stomatognathic system.

That craniofacial interrelation was obtained from two (2D) or three dimensional (3D)

analysis of cephalometric images in the identification still remains unclear. This study

was designed to clarify dimensional changes and pattern variations of the vomer

bone in a different dentofacial discrepancy.

Methods: Anatomical landmarks examinations were performed on 96 patient’s cone

– beam computed tomography (CBCT) image to determine vomer bone outline of

Turkish adult patients. The vomeral outline determination was done by using cropping

tools of the software algorithm. The vomer bone components within midface were

identified, connected and linear references were taken horizontally between anterior

maxilla base plane and vomer base plane. The vomeral components were spliced,

measured, and reconstructed in a three-dimensional model using MIMICS 19.0

version (Mimics®, Materialize, Leuven, Belgium) software. The vomer bone pattern

was classified into 3 main type groups that were statistically analyzed among study

groups respectively.

Results: A high significant with a positive correlation of the different vomeral

components and three pattern model with different dentofacial profiles were found.

Also, the vomer bone variations were more severe in male than female (p<0.01).

No statistically significant between the vomeral components of cases and mean age

(p>0.05) were determined.

Conclusion: The results of this study provide fine details of surgical anatomy

knowledge of the vomer bone pattern that can be used as a valuable reference for

Orthodontic and Orthognathic procedures.
