AIMS AND OBJECTIVES
The aim of this article is to re-evaluate anchorage coefficient values in orthodontics and their influence in the treatment decision through the usage of three-dimensional (3D) scanner.
MATERIALS AND METHODS
A sample of 80 patients was analyzed with the 3D scanner using the C2000 and Cepha 3DT softwares (CIRAD Montpellier, France). Tooth anatomy parameters (linear measurements, root, and crown volumes) were then calculated to determine new anchorage coefficients based on root volume. Data were collected and statistically evaluated with the StatView software (version 5.0).
RESULTS
The anchorage coefficient values found in this study are compared to those established in previous studies. These new values affect and modify our approach in orthodontic treatment from the standpoint of anchorage.
CONCLUSION
The use of new anchorage coefficient values has significant clinical implications in conventional and in microimplants-assisted orthodontic mechanics through the selection and delivery of the optimal force system (magnitude and moment) for an adequate biological response.
目的
本文旨在通过使用三维（3D）扫描仪重新评估正畸中的支抗系数值及其对治疗决策的影响。
材料与方法
使用C2000和Cepha 3DT软件（法国蒙彼利埃国际农业研究与发展中心），通过3D扫描仪对80例患者的样本进行分析。然后计算牙齿解剖参数（线性测量、牙根和牙冠体积），以根据牙根体积确定新的支抗系数。使用StatView软件（5.0版）收集数据并进行统计评估。
结果
将本研究中发现的支抗系数值与先前研究中确定的值进行比较。从支抗的角度来看，这些新值影响并改变了我们的正畸治疗方法。
结论
通过为适当的生物学反应选择和提供最佳力系统（大小和力矩），新支抗系数值的使用在传统正畸力学和微种植体辅助正畸力学中具有重要的临床意义。
