蒙汉族下颌孔位置的CBCT测量对照研究

Measurement and contrast study of the Location of Mandibular Foramen in Mongolian and Han Nationality Using CBCT

目的本研究应用CBCT对内蒙古地区蒙汉族正常成人下颌升支区进行CBCT扫描。方法选取牙合正常蒙汉族成年人各30名,采用CBCT进行下颌骨升支区扫描,利用应用软件Invivo-dental进行三维重建,定位标记点,测量下颌孔的位置。对所测量的数据进行分析。结果 (1)各项测量值经统计学处理,获得蒙汉族正常成年人相关测量值。(2)蒙汉族左右两侧各项对应数据比较,差异无统计学意义(P>0.05)。(3)下颌孔的位置蒙古族男女、汉族男女、蒙汉族女性比较,差异有统计学意义(P<0.05),蒙汉族男性比较,差异无统计学意义(P>0.05)。结论 (1)利用应用软件Invivo-dental进行三维重建和测量,图像清晰,数据准确。(2)总结了内蒙古地区蒙汉族正常成人下颌孔位置的解剖特点。

Objective The research on the application of CBCT in Inner Mongolia Han and Mongolia normal adult mandibular ramus area by CBCT scanning.Methods Select the normal occlusion of Han and Mongolian Adults in 30, with CBCT of mandibular ramus area scanning, 3D reconstruction by using the software Invivo-dental, the location of markers, measurement of mandibular foramen position. The measured data were analyzed.Results （1） the measured values obtained by statistical processing, the Mongolian and Han normal adults related to the measured value. （2） the left and right sides of the Han and Mongolian data comparison, no statistically significant difference （P〉0.05）. （3） the location of the mandibular foramen of Mongolian Han men and women, men and women, between Mongolian and Han women, was statistically signicant the difference （P〈0.05）, Mongolian and Han men, there was no statistically signicant difference （P〉0.05）.Conclusion （1） using the software Invivo-dental to carry out three-dimensional reconstruction and measurement, the image is clear, the data is accurate. （2） summarizes the anatomy characteristic of the mandibular hole position of Mongolian and Han nationality normal people in Inner Mongolia area.
