现代正畸学和正颌外科需要准确识别下颌骨不对称，以提高此类畸形的诊断和治疗计划。虽然颅面畸形是非常常见的病理，但某些类型的不对称在没有适当的诊断工具的情况下可能非常难以评估。本研究的目的是实施三维（3D）分割程序的使用，以确定在不同的垂直和矢状模式的成人患者的下颌骨水平的不对称性，其中不对称性可能会被忽视的观察水平。研究样本包括60名成年患者（33名女性和27名男性，年龄在18至60岁之间）。受试者被分为3个矢状和垂直骨骼组。使用ITK-SNAP®和3DSlicer®软件将CBCT图像分割、镜像并基于体素与参考标志配准。构建三维表面模型，以评估不同解剖水平的不对称程度。存在一定程度的不对称，左半下颌骨倾向于包含右半下颌骨（0.123 ± 0.270 mm（CI 95% 0.036-0.222; p < 0.001）。虽然受试者在下颌骨不对称性和他们的矢状或垂直骨骼模式之间没有显着差异（分别为p = 0.809和p = 0.453），根据解剖区域发现了统计学显著差异（p < 0.001; CI 95%=1.020-1.021），髁状突较高，其次是升支和体部。虽然下颌骨不对称不能与对称患者的垂直和矢状面骨骼模式相关，但有关3D分割程序和彩色图的知识可以为识别下颌骨不对称提供有价值的信息。
An accurate identification of mandibular asymmetries is required by modern orthodontics and orthognathic surgery to improve diagnosis and treatment planning of such deformities. Although craniofacial deformities are very frequent pathologies, some types of asymmetries can be very difficult to assess without the proper diagnostic tools. The purpose of this study was to implement the usage of three-dimensional (3D) segmentation procedures to identify asymmetries at the mandibular level in adult patients with different vertical and sagittal patterns where the asymmetries could go unnoticed at the observational level. The study sample comprised 60 adult patients (33 women and 27 men, aged between 18 and 60 years). Subjects were divided into 3 sagittal and vertical skeletal groups. CBCT images were segmented, mirrored and voxel-based registered with reference landmarks using ITK-SNAP® and 3DSlicer® software’s. 3D surface models were constructed to evaluate the degree of asymmetry at different anatomical levels. There was a degree of asymmetry, with the left hemimandible tending to contain the right one (0.123 ± 0.270 mm (CI95% 0.036–0.222; p < 0.001). Although the subjects under study did not present significant differences between mandibular asymmetries and their sagittal or vertical skeletal pattern (p = 0.809 and p = 0.453, respectively), a statistically significant difference has been found depending on the anatomical region (p < 0.001; CI95%=1.020–1.021), being higher in the condyle, followed by the ramus and the corpus. Although mandibular asymmetries cannot be correlated with vertical and sagittal skeletal patterns in symmetric patients, knowledge about 3D segmentation procedures and color maps can provide valuable information to identify mandibular asymmetries.
