McNamara cephalometric analysis for Shijiazhuang adults with normal occlusion

Objective To study the teeth,jaws and craniofacial structures of Shijiazhuang adults with normal occlusion by using McNamara Analysis, so as to establish the norms of McNamara Analysis for Shijiazhuang adults with normal occlusion and to provide the reference for clinical diagnosis, design and treatment evaluation of orthodontic and orthognathic surgery.Methods McNamara Analysis was conducted on the basis of the laterial cephalograms of 74 Shijiazhuang adults with normal occlusion and the data obtained was compared with that of Shanghai.Results A normal range of measurements and the craniofacial structure feathers of Shijiazhuang adults with normal occlusion were obtained by using McNamara Analysis. In Shijiazhuang adults the effective maxillary length, the effective mandibular length,the anterior facial height, the upper incisor to point A vertical were larger in male than those in female. The effective maxillary length, the effective mandibular length and the upper incisor to point A vertical of Shijiazhuang male were larger than those of Shanghai male.Conclusion McNamara Analysis reflect the relationship of the mandible to the maxilla quantitatively, the linear parameters are comparable.
