Abstract:
Objective To establish the differential templates of juvenile and children in Shandong with normal occlusion, according to the group of skeletal age. Methods 212 juvenile and children at the age of 8-16 years (107 males and 105 females) with normal occlusion in Shandong natives were took cephalomatric radiographs, and divided into different groups by cervical vertebrae skeletal age. Then these cephalomatric radiographs were scanned on the computer and 14 skeletal landmarks were vectorizated. An analytical method of Ricketts and McNamara with WinCept 7.0 was used to make statistics and variance analysis among gender and every group of cervical vertebrae skeletal age,and then established the templates. Results The juvenile and children in Shandong natives with normal occlusion had different templates. Conclusion By overlapping the same skeletal age of templates by SN plane, we can see that male face outline is greater than female and male mandibular plane angle is smaller than female. By overlapping the same gender of templates, there is a developmental trend of mandibular bone to be forward and downward, and to revolve anticlockwise with age.
