得益于CIRAD建模实验室和Jacques Treil之间的长期合作，一种来自扫描仪采集的3D头部测量分析方法已经开发出来。骨骼描述模型是基于与面部生长的神经基质轴相关的八个标志（颧头、眶上、眶下、颏下点）；它已经被大量描述过了。这项工作的目的在于提出牙槽水平的分析。拱和齿的描述和标记主要依赖于系统地使用数学工具，计算中心惯性矩阵，以及三个基本选择：从牙弓组成的牙齿中识别牙弓，抛开任何牙槽标记，每颗牙齿相对于牙弓的标记，这可以通过正畸医生的眼睛观察到，而不是相对于颅面结构，通过牙冠根轴的方向而不是其唯一的颊侧来定义每颗牙齿的位置，它们在正畸学中的用途很多：诊断、力学选择、治疗模拟、治疗随访、结果分析……临床应用说明了理论介绍。
A 3D cephalometric analysis method from a scanner acquisition, has been developed thanks to a long collaboration between the CIRAD modeling Laboratory and Jacques Treil. The model of skeletal description is based on eight landmarks related to the neuromatrical axis of facial growth (heads of the mallei, supraorbital, suborbital, submental points); it has been abundantly described. The purpose of this work consists in presenting the dentoalveolar level of the analysis. The description and the marking of the arches and the teeth mainly rest on the systematic use of a mathematical tool, the calculation of the central matrix of inertia, and on three fundamental choices: the identification of the dental arches from their constituting teeth leaving aside any alveolar marking, the marking of each tooth relative to the arch, as it can be observed by the orthodontist's eye, and not relative to the craniofacial architecture, the definition of the position of each tooth by the orientation of its coronoradicular axis and not its sole buccal side, Their uses in orthodontics are numerous: diagnosis, choice of the mechanics, therapeutic simulation, therapeutic follow up, analysis of the findings... Clinical applications illustrate the theoretical presentation.
