| 中文摘要:目的 测量分析蒙汉民族上颌第2前磨牙与第1磨牙根间隙硬组织形态的数据，为口腔颌面外科、正畸科在临床治疗过程中口内支抗的设立提供参考。方法 使用多层螺旋CT对选取的60例正常大学生进行上颌骨扫描后，利用计算机软件测量釉牙骨质界下方不同层面中根间隙宽度、颊侧皮质骨厚度、牙槽嵴宽度，所得数据进行统计学分析及处理。结果 所得各项测量数据在上颌左右两侧对比，差异无统计学意义（P>0.05）。正常成年人上颌第2前磨牙与第1磨牙之间硬组织测量值在不同的测量平面内，男女之间存在不同程度的差异（P<0.05），而蒙汉族之间差异无统计学意义（P>0.05）。结论 作为颌间牵引钉的常规植入部位，其硬组织形态存在明显个体差异，在植入前应对该区域进行足够的测量分析。 |

| Abstract:Objective To provide the reference about setting up intraoral anchorage in the clinical course for the oral and maxillofacial surgery and orthodontic surgery treatment of subjects, by measuring and analyzing interradicular space between maxillary second premolar and the first molar including the Mongolian and Han nationality. Methods After the multi-slice spiral CT was used to scanning maxillary bone of 60 university students with normal occlusion, the data were made scientific researches by computer software, including the interradicular distances, the thickness of buccal cortical bone and the width of alveolar process in different planes. The data were statistically treated and analyzed. Results There was no significantly statistical difference (P>0.05) between both sides of maxilla hard tissue. There was a significantly statistical difference (P<0.05) between male and female, but no significantly statistical difference (P>0.05) between Han and Mongolian in different planes of hard tissue between the maxillary second premolar and the first molar. Concusion Beacause there is a significant individual difference on the shape of hard tissue as the normal location for traction screw implanting, the region should be measured and analyzed before implantation. |
