To describe the cephalometric characteristic of skeletal Class II malocclusion in Javanese Population at Universitas Airlangga Dental Hospital.
A total of 118 lateral cephalograms of preorthodontic patients with skeletal Class II malocclusion were obtained from Universitas Airlangga Dental Hospital. The lateral cephalograms were analyzed using digital cephalometric analysis to determine the ANB, mandibular length, facial axis, Y-axis, sella to nasion-mandibular plane (SN-MP), and lower anterior facial height (LAFH). Correlation between mandibular length and other variables was analyzed using Pearson correlation test with < 0.05.
There was an increase of ANB, Y-axis, SN-MP, and LAFH. While SNB was decrease and mandibular length was shortened. There was a significant correlation between mandibular length and other variables, such as facial axis, SN-MP, LAFH, and ANB.
Skeletal Class II malocclusion in Javanese Population at Universitas Airlangga Dental Hospital was characterized by short mandibular length and large ANB mostly not by the increased of SNA but by the lack of SNB. The length of mandible correlated with facial axis angle, lower anterior facial height, and mandibular plane angle.
描述印度尼西亚艾尔朗加大学牙科学院爪哇族人群骨骼Ⅱ类错牙合畸形的头影测量特征。
从印度尼西亚艾尔朗加大学牙科学院获取118例骨骼Ⅱ类错牙合畸形正畸治疗前患者的头颅侧位片。使用数字头影测量分析法对头颅侧位片进行分析,以确定ANB、下颌长度、面轴、Y轴、蝶鞍至鼻根点-下颌平面(SN-MP)以及下前牙面部高度(LAFH)。采用Pearson相关检验分析下颌长度与其他变量之间的相关性,检验水准为α<0.05。
ANB、Y轴、SN-MP和LAFH增加。而SNB减小,下颌长度缩短。下颌长度与其他变量之间存在显著相关性,如面轴、SN-MP、LAFH和ANB。
印度尼西亚艾尔朗加大学牙科学院爪哇族人群的骨骼Ⅱ类错牙合畸形特征为下颌长度短和ANB大,主要不是由于SNA增加,而是由于SNB不足。下颌长度与面轴角、下前牙面部高度和下颌平面角相关。
