Finite point return generation method for bending motion planning of orthodontic arch wire

Abstract

The invention provides a finite point return generation method for bending motion planning of an orthodontic arch wire and relates to the technical field of bending of the orthodontic arch wire. The finite point return generation method for bending motion planning of the orthodontic arch wire is obtained on the basis of an information set of shaping control points of an orthodontic arch wire curveand a robot motion information set of the shaping control points in combination with motion characteristics of a robot for bending the orthodontic arch wire according to the individual orthodontic arch wire curve of a patient. The technical key points are as follows: the information set M of the shaping control points of the orthodontic arch wire curve and the robot motion information set N of the shaping control points are input into an orthodontic arch wire bending system according to the individual orthodontic arch wire curve of the patient; the individual orthodontic arch wire curve is divided; the number of the control points in each divided area is calculated, and all the areas are arranged in descending order; a reverse bending information set is calculated; whether interference occurs at bending points is detected.

Description

technical field [0001] The patent of the present invention relates to a finite point search and generation method for motion planning of orthodontic arch wire bending, which belongs to the technical field of orthodontic arch wire bending. Background technique [0002] With the improvement of living standards, more and more attention is paid to beauty and health. A beautiful appearance and a healthy body can bring people confidence, but the occlusal jaw, which has always been called the facade, sometimes hinders the realization of this wish. The health of the jaw not only directly affects the beauty of the face, but also relates to the normal oral function. Oral malocclusion is a major oral disease that endangers human health. It has a high incidence rate. In clinical oral treatment, patients often wear orthodontic appliances. In recent years, with the development of digital manufacturing technology, the digital processing of arch wires in orthodontic appliances has become an...
