To evaluate the mean cephalometric values for Steiner Analysis in bihar population.
To evaluate the cephalometric features of a bihar population and to present_an organized, comprehensive cephalometric norms for Steiner cephalometric analysis.. To introduce mean values to assess skeletal, dental and soft tissue relationship using Steiner analysis for orthodontic diagnosis.. To compare standards that will be derived with the earlier established norms for other population.
The study was conducted in the Department of orthodontics and dentofacial orthopedics,Buddha Institute of Dental Sciences And Hospital,Patna(Bihar). The sample was collected from the out patient department of the same college.
The present analysis was made on lateral cephalograms of 60 subjects with well balanced and acceptable facial profile of Bihar population. The subjects were informed about the purpose of the study.
Subjects with age group of 18-26 years with dento-alveolar class I malocclusion and acceptable facial profile were selected by trained orthodontists, who belonged to the department of orthodontics and dentofacial orthopedics,Buddha Institute of Dental Sciences And Hospital.
There was increase in SNA angle, SNB angle, SND angle,in Bihar population than Caucasians. Bihar population has proclined and forwardly placed upper and lower incisors, which was indicative of bimaxillary protrusion as compared to Caucasians. Bihar population had protrusive upper and lower lips as compared to Caucasians. Bihar population males had tendency towards horizontal growth pattern of the mandible than females. Bihar females had more proclined lower incisors than males.
评估比哈尔人群Steiner分析法的平均头影测量值。
评估比哈尔人群的头影测量特征,并提出用于Steiner头影测量分析的系统、全面的头影测量标准。采用Steiner分析法引入平均值来评估骨骼、牙齿和软组织关系,以用于正畸诊断。将得出的标准与其他人群先前确立的标准进行比较。
本研究在巴特那(比哈尔邦)佛牙科学与医院正畸与牙颌面正畸科进行。样本取自同一学院的门诊部。
本分析基于60名比哈尔人群受试者的头颅侧位片,这些受试者面部轮廓匀称且可接受。已向受试者告知研究目的。
由佛牙科学与医院正畸与牙颌面正畸科训练有素的正畸医生挑选年龄在18 - 26岁、牙列Ⅰ类错 且面部轮廓可接受的受试者。
与高加索人相比,比哈尔人群的SNA角、SNB角、SND角增大。与高加索人相比,比哈尔人群的上下切牙前倾且位置靠前,这表明存在双颌前突。与高加索人相比,比哈尔人群的上下唇前突。比哈尔人群男性下颌骨呈水平生长模式的倾向比女性更明显。比哈尔人群女性的下切牙比男性更前倾。
