Abstract:
OBJECTIVEThe purpose of this study was to obtain the normal value of McNamura analysis for Chengdu adolescents with normal occlusion of early permanent dentition.
METHODSMcNamara 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.
RESULTSThere 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.
CONCLUSIONThere is significantly difference in values of normal occlusions of McNamara analysis among different regions and different races.
