【摘要】 目的:本研究旨在利用螺旋CT检查数据,经过Mimics软件处理后观察和测量颏管的解剖解剖结构,以减少颏管区种植手术的损伤。方法:先把螺旋CT数据以DICOM 3.0格式保存,接着导入Mimics软件,在螺旋CT的二级重建图像上,进行观察和测量。结果:颏孔前3mm冠状面的测量项目(管下缘距、颏管横径、纵径、管嵴距,管舌和管颊距),左右对比差异无统计学意义;女性比男性小(P<0.05);对下颌骨颏管区的解剖结构可以在可视化三维数字模型上进行多方位对测量和综合评价。结论:螺旋CT与Mimics软件结合,可以对颏管区种植术前进行准确的确测量,并且可以建立可视化的三维模型。更多还原

【Abstract】 Objective To observe the anatomical characteristics of mental canal area and analysis the data by Mimics software, in order to prompt the injured risks to anatomical structure by dental implantation in this area. Methods The CT digital imaging data were saved as DICOM 3.0files,transformed to two-grade reconstructed images of,and then measured by the Mimics software.Results Regarding the diameter and longitudinal diameter of the mental foramen,the horizontal distance of mental canal,the canal-crest distance, canal-inferior distance,canal-lingual distance,canal-buccal distance,the diameter and longitudinal diameter of the mental canal in the two coronal plane, which were 3mm away from the mental foramen,there were no statistically significant differences between left and right in the same gender.However,there were statistically significant differences(P<0.05) about comparisons in different gender.data,which were converted into a visual 3D digital models by mimics softwares,could provided sufficient information, measure and given comprehensive evaluation about the anatomic structureof mandibular mental canal. Conclusion Combined with Mimics software, Spiral CT affords the precise measurement before the dental implantation in mental canal area,and establishes visual 3D model. It provides assistances for the doctor-patient communication,diagnosis, treatment and curative effect evaluation on dental implant.更多还原
