摘要
目的研究蒙古族正常成年人颅颌面硬组织的三维头影测量正常值,为正颌外科提供临床诊断、治疗计划及手术方案制定的数字依据。方法对48名符合正常标准的三代蒙古族后裔成年人进行颅颌面螺旋CT薄层扫描,用三维软件重建颅颌面硬组织三维图像,在屏幕上定点测量37项线距和19项角度。结果获得了蒙古族正常成年人颅颌面硬组织双螺旋CT三维头影测量正常值。结论①蒙古族正常成年人颅颌面硬组织的差异主要体现在骨骼大小上,而在骨骼轮廓和比例关系上差异较小,蒙古族女性的下颌开张度大于男性,而男性较女性面部前凸。②蒙古族正常成年人颅颌面硬组织结构左右也存在着一定程度的属于正常形态变异的不对称现象。③蒙古族正常成年人颅颌面硬组织形态具有明显的性别差异及种族特点,在正颌外科的临床诊断、治疗计划、手术方案的制定及术后面形预测应参考蒙古族自身的正常值。
Objective To obtain the three- dimensional cephalometric values for the Mongolian adults with normal occlusion. Methods The craniomaxillofacial hard tissue of 48 Mongolian adults （mate 25, female 23） with normal occlusion was scanned by the Spiral CT. Three - dimensional images of craniomaxillafacial bones were reconstructed by a 3D program and 37 items of length and 19 items of angle were measured on the image. Results The cephalometric values of the 37 items of length and 19 items of angle were collected. Conclusion The cephalometric values showed that Mongolian have some obvious features as compared with other races. The data may be useful in the fields of orthognathic surgery.
