The purpose of this study was to obtain the normal value of McNamura analysis for Chengdu adolescents with normal occlusion of early permanent dentition.
McNamara analysis was conducted on the basis of the lateral cephalograms of 67 Chengdu adolescents with normal occlusions, and the obtained data was compared with that of Shanghai adolescents and McNamara.
There was no difference in the normal value of McNamara analysis between male and female Chengdu adolescents. The Comparative results between Chengdu and Shanghai adolescents indicated significantly larger values of Shanghai adolescents in effective middle facial lengths, mandibular lengths and lower anterior facial heights. The vertical distances from the upper incisor to point A and, from the lower incisor to A-Po line of Chengdu adolescents were larger than those of white adolescents.
There is significantly difference in values of normal occlusions of McNamara analysis among different regions and different races.
本研究旨在获取成都早期恒牙列正常咬合青少年的麦克纳马拉分析法正常值。
对67名成都正常咬合青少年的头颅侧位片进行麦克纳马拉分析法,并将所得数据与上海青少年及麦克纳马拉的相关数据进行比较。
成都青少年男女之间麦克纳马拉分析法的正常值无差异。成都与上海青少年的比较结果表明,上海青少年在有效中面部长度、下颌长度和下面部高度方面的值显著更大。成都青少年上切牙至A点以及下切牙至A-Po线的垂直距离大于白人青少年。
不同地区和不同种族之间麦克纳马拉分析法正常咬合值存在显著差异。
