摘要
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角度,应用SPSS13.0统计软件包对数据进行处理,利用逐步多元回归分析法研究软硬组织的相关性。结果:鼻突度与上颌骨突度及下颌平面角相关,上唇突度与上颌骨突度及上中切牙倾斜度相关,下唇突度与上下颌骨突度及上颌中切牙倾斜度相关,颏部突度与上下颌骨突度相关,鼻唇角与硬组织相关性较小,颏唇沟角与下颌平面角及下颌前份高度相关。结论:颌骨的位置形态及上中切牙的倾斜程度与鼻唇颏部软组织侧貌有较大相关性,同时,软组织形态具有一定的独立性。
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.
