成年女性错[牙合]畸形患者颅颌面软硬结构关系的研究

目的：研究成年女性错[牙合]畸形患者软组织侧貌特征与颅颌面骨骼及牙齿的相关性，找出对软组织侧貌影响明显的骨性或牙性畸形。材料与方法：收集120例成年女性错[牙合]畸形患者（年龄18岁-26岁，平均年龄23．5岁）治疗前头颅侧位片，利用Delaire头影测量分析方法测量颅颌面骨骼结构异常程度及鼻唇颏部侧貌软组织突度及相关...

The correlation of craniofacial hard tissue structure and soft tissue proffie among female adults with malocclusion

Objective： To investigate the relationship of soft tissue profile and craniofacial hard tissue characteristics among female adults with craniofacial deformity, and to find out the structure that can affect the profile remarkably, Methods： One hundred and twenty cephalometric films of female adults with craniofacial deformity aged from 18 to 26 years before orthodontic treatment were collected and measured with Delaire cephalometric analysis, the results were assessed by SPSS13.0 software package,and multiple regression analysis was used to examine the relationship of and craniofacial characteristics variation and soft tissue profile trait. Results：Nose prominence correlated with maxilla prominence and mandibular plane, upper lip prominence correlated with maxilla prominence and inclination of upper middle incisor, lower lip correlated with the prominence of maxilla and mandible as well as inclination of upper lip prominence, nasolabial angle has no remarkable correlation with skeletal and dental structure, mentolabial sulcus angle correlated with mandibular plane and anterior height of mandible. Conclusions： The position of maxilla and mandible and teeth were partly related with soft tissue profile, and soft tissue profile has independence to some extent.
