Purpose: To establish the normal values of cephalometric items for children with normal occlusion in Shandong province, and study the growth tendency of them and analyze the characteristics in different skeletal stages and sexes.
Methods: Lateral cephalograph was taken in 172 children of Han nationality with normal occlusion in Shandong province. The pictures were processed by WinCeph7.

Purpose: To establish the standard values of roentgengraphic cephalometry in children with normal occlusion in Shandong district and to make the facial model.
Methods: 156 children were selected to take lateral cephalograph, and were divided into two groups: mixed dentition and early permanent dentition. Cephalograms were analyzed for all subjects with WinCeph7.
Objective: To investigate the displacement, the position of rotation center and the stress distribution of PDL under different loading force system (Moment/Force, M/F) by simulating clinical loading force system.
Methods: A three-dimensional finite element model of upper central incisor, which consists of 945 isoparametric elements and 1,245 nodes was developed. The displacement, the position of the rotation center and the stress distribution of PDL were analyzed under 13 types of loading force system.

Objectives: To investigate different type of tooth movement under different force systems by simulating clinical loading force systems.
Methods: Develop a three-dimensional finite element model of upper central incisor, which consists of 945 isoparametric elements, 1245 nodes. Analyse the types of tooth movement under different force system with a horizontal force of 1 N being applied at the upper central incisor.
