【摘要】：目的:建立大致正常成年汉族人群下颌骨三维形态测量方法并初步获取其三维形态测量平均值,为建立三维虚拟可变形下颌骨平均值模型提供前提。方法:利用现有大致正常成年汉族人群头颅三维CT数据库(54例),应用三维重建和测量软件Mimics 10.01,建立下颌骨外形轮廓三维测量方法。SPSS 13.0统计软件对所获得的数据进行整理分析。结果:获得大致正常成年汉族人群男性和女性下颌骨各部位长度、宽度、高度、深度、厚度、角度等84组均数和标准差,其中66组测量项目在男、女间差异存在统计学意义,16组测量数据男、女间差异无统计学意义,且此16组测量数据在下颌骨表面分布具有对称性。成年男性和女性下颌骨外形轮廓高、宽、深度间不具相关性。结论:大致正常成年汉族人群男性和女性下颌骨形态长、宽、深、高度各具特点,男、女个体下颌骨三维形态各具特征。
[Abstract]:Objective: to establish a three-dimensional morphological measurement method of mandible in normal adult Han population and to obtain the mean value of three-dimensional morphology measurement. Methods: 54 cases of cranial CT database of normal adult Han population were used to establish the mean value model of virtual deformable mandible. The external mandible was established by using Mimics 10.01, a 3D reconstruction and measurement software. SPSS 13.0 statistical software was used to analyze the data obtained. Results: the length of mandible in male and female adults was obtained. Width, height, depth, thickness, angle and so on 84 groups of mean and standard deviation, 66 groups of measurement items in men and women were statistically significant in 16 groups of measurement data, there was no significant difference between women and men. There was no correlation between the contour, width and depth of mandible in adult male and female. Conclusion: the mandibular shape of male and female adult Han nationality is long and wide. The depth and height of mandible have their own characteristics, and the mandible of male and female have their own characteristics.
