摘要

在本文中，我们提出了一种新的正畸金属丝设计系统（OWDS），它允许医务人员在三维断层医学图像上设置支架的附着位置和方向。为了实现机器人对正畸金属丝的全自动化加工，提出了一种基于齐次变换的几何设计金属丝建模方法。提出了一种新的自定义线材优化设计算法，使线材长度最短，满足线材安装的约束条件。通过导线几何设计实例和数值实验，验证了该方法的有效性。

Medical image-based 3D orthodontic wire optimization considering constraints at bracket and processing points.

In this paper, we propose a new orthodontic wire design system (OWDS) that allows medical staff to set the bracket attachment position and direction on a 3D tomographic medical image. To enable fully automated processing of the orthodontic wire by a robot, a method for modeling the geometrically designed wire based on homogeneous transformation is proposed. A new custom algorithm is proposed for optimal wire design, which results in the shortest length that satisfies the constraints required for wire mounting. Through case studies of wire geometry design and other numerical experiments, the effectiveness of the proposed method is verified.
