| 摘 要： | 目的建立哈尔滨地区正常恒牙颅面三维CT测量项目和参考值范围。方法采用螺旋CT和AW4.2工作站对58例哈尔滨地区17~25岁正常恒牙青年颅颌面硬组织重建测量,并进行统计分析。结果角度测量项目基本无性别差异,绝大多数线距测量值男性组显著大于女性组;面前部及颅底项目比值无性别差异,N-ANS∶ANS-Me∶N-Me约为0.46∶0.56∶1,SN∶Ba-S∶N-Ba约为0.57∶0.52∶1;左右测量项目间无统计学差异;下颌非对称率<2.5%(2.4°或2.3 mm)。结论建立了哈尔滨地区成年人恒牙三维CT颅颌面硬组织正常值数据库。线距测量有性别差异,男性较大;男女两组间角度测量值及面部比率呈较高的一致性;GoL-S-GoR是一理想的美学三角;该方法对面部不对称性畸形分析较为可靠。

| Abstract: | Objective To establish the diagnosis items and normal value range by CT three-dimensional measurement on permanent normal occlusion of Harbin adults,and to provide a fixed quantity foundation of diagnosis,treatment and design for orthodontics and orthodontical surgery.Methods 58 Harbin adults(male:29 and female:29) aged from 17 to 25 with normal occlusion were chosen.The craniomaxillofacial hard tissue was scanned by means of the Spiral CT.Then the 3D images of craniomaxillofacial bones were reconstructed o... |
