目的:建立甘肃省保安族正常恒牙初期牙软组织侧貌的X线头影测量Burstone分析法的正常值,并探讨其软组织侧貌的性别特征。方法:选取保安正常恒牙初期牙儿童265例(男135例,年龄13.71±1.83岁;女130例,年龄12.52±1.64岁),摄取标准头颅侧位定位片,应用Dolphin Imaging软件选取标志点,并进行计算机辅助测量,采用SPSS13.0软件包进行统计学分析,对其颌面部软组织侧貌进行性别的特征分析,并与正常汉族青年的数据进行对比讨论。结果:得到Burstone分析法的正常值标准。结论:男女软组织侧貌发育特征很相近,但仍存在一定差异,颏唇沟深(Si-LiPg′),鼻唇角(Pn-Sn-Lso),下唇突距(Li-SnPg′)女性大于男性,上下唇长度比(Sn-Stms/Stmi-Me),面部高度男性大于女性,保安族人男性唇部和面中部软组织侧貌比女性明显突出。了解正常牙牙人群软组织侧貌的发育特征,有助于临床诊断及矫治计划的制定。
OBJECTIVE: To establish the normal value of Burstone analysis by X-cephaplex analysis of soft tissue profile of Bao’an normal permanent teeth in Gansu Province during the initial period and investigate the gender characteristics of soft tissue profile. Methods: A total of 265 children (135 males and 13.71 ± 1.83 years old and 130 females, aged 12.52 ± 1.64 years) with normal permanent dentition were enrolled in this study. The standard cephalometric flaps were taken. Dolphin Imaging software was used to select landmark points , And computer aided measurement was carried out. SPSS 13.0 software package was used for statistical analysis. Sexual characteristics of the maxillofacial soft tissue profile were analyzed and compared with the data of normal Han youth. Results: The Burstone analysis of the normal standard. CONCLUSIONS: The morphological characteristics of soft tissue in men and women are similar, but there are still some differences. The Si-LiPg ’, Pn-Sn-Lso and Li-SnPg’ Greater than male, Sn-Stms / Stmi-Me, male at face height was higher than female at the same time. To understand the developmental features of soft tissue profile of normal dental crowds is helpful for the development of clinical diagnosis and correction plans.
