Problems solved by technology

[0005] In view of the above problems, the present invention proposes a method for determining the equal angle division angle of orthodontic arch wire bending sequence planning, which solves the problem of lack of determination of the division angle when the orthodontic arch wire is divided into equal angles at present, and is beneficial to bending Reasonable planning of the bending sequence avoids interference during the bending process of the robot, and then realizes efficient digital bending of orthodontic archwires

Embodiment 2

[0071] Embodiment 2: as figure 2 As shown, in the process of determining the angle division angles such as the bending sequence planning of a personalized orthodontic archwire curve, such as image 3 As shown, assuming that through the calculation of step two, the initial number of equal-angle divisions is a=6, and by continuing to step three, the division angle β determined under the initial number of equal-angle divisions can be calculated. Generate 6 iso-angle domains with the same angle on the archwire curve, and then proceed to step 4 to judge whether the number of divisions should be increased, that is, judge from the first iso-angle domain, and judge the bending point density of its iso-angle domain And the angle-to-distance ratio of the bending point in the equiangular domain and Whether the set density of bending points in the equal-angle domain and the angle-distance ratio and upper limit of the bending point in the equal-angle domain are satisfied at the same ti...

Abstract

The invention relates to the technical field of orthodontic arch wire bending, in particular to an equal-angle division angle determination method for orthodontic arch wire bending sequence planning.When equal-angle division is used to plan the bending sequence for an orthodontic arch wire, based on an orthodontic arch wire curve forming control point information set and a robot motion information set of forming control points, an upper limit value of the bending point density of an equal-angle region and an upper limit value of a bending point angular distance ratio sum of the equal-angle region are set in combination with the orthodontic arch wire bending characteristic of a robot; the equal-angle division angle determination method for orthodontic arch wire bending sequence planning isestablished; a division angle is changed according to the bending point density and the bending point angular distance ratio sum of the equal-angle region in the equal-angle division process; and finally the division angle is determined and output. Through quantitative constraint on the bending point density and the bending difficulty of the divided region, the rationality of division angle determination is ensured, and the planning efficiency is improved.

Description

technical field [0001] The patent of the present invention relates to an orthodontic arch wire bending sequence planning and other angle division angle determination method, which belongs to the technical field of orthodontic arch wire bending. Background technique [0002] Malocclusion is the third largest oral disease that endangers human health, showing a high incidence rate. In modern stomatology, fixed orthodontics is a commonly used and effective orthodontic treatment, and the bending of orthodontic archwires is a fixed In recent years, the key to orthodontic technology has been deeply influenced by digital manufacturing technology. The traditional oral manufacturing process is undergoing revolutionary changes. The field of orthodontics is also benefiting from digital technology. The processing of arch wires in orthodontic appliances is becoming digital. develop. [0003] Orthodontic archwire bending sequence planning is a necessary prerequisite for digital bending of...
