“…Complex. Te postprocessing three-dimensional model of nasomaxillary complex is imported into the fnite element analysis software ANSYS workbench'19.0 (analysis system) [12], the boundary and contour lines of the threedimensional solid model are established, and the tiny points, lines, and surfaces that have or may have an impact on the modeling are manually processed, and the model is divided into regular modules. When delimiting, the element size is set to 1 mm, 2 mm, and 3 mm, respectively.…”

Nasal bone is a long, paired series of small bones, which is narrow at the top and broad at the bottom, that forms the base of the nasal dorsum. Together with the nasal part of the frontal bone, the frontal process of the maxilla and the middle plate of the ethmoid bone constitute the bone scaffold of the external nose. In this paper, the DICOM image data file was imported into the Mimics software for 3D reconstruction. At the same time, the Geomagic software was used for relevant image processing, and the finite element software ANSYS was used to establish a finite element model to analyze the stress characteristics of the nasomaxillary complex. Results. The maximum principal stress and maximum strain force at the lower segment of nasal bone and the junction of nasal bone and maxilla were relatively large. When the same external force acts on the lower segment of the nasal bone and the angle is 0° (sagittal force), the maximum principal stress and maximum strain force are the smallest. When the angle continues to increase, the maximum principal stress and maximum strain force continue to increase.
