An Orthodontic Archwire Bending Sequence Planning Method Based on Equiangular Partitioning

Abstract

The invention discloses a uniform angle division orthodontic arch wire bending sequence planning method and relates to the technical field of orthodontic arch wire bending techniques. The uniform angle division orthodontic arch wire bending sequence planning method is provided according to individual orthodontic arch wire curves of patients, on the basis of an orthodontic arch wire curve formationcontrol point information set and a robot movement information set of formation control points and with the combination of characteristic that an orthodontic arch wire is bent by using a robot. The method is technically characterized by comprising the following steps: according to the individual orthodontic arch wire curves of patients, inputting the orthodontic arch wire curve formation controlpoint information set M and the robot movement information set N of the formation control points into an orthodontic arch wire bending system; dividing the individual orthodontic arch wire curves; andsequencing divided uniform division domains.

Description

technical field [0001] The patent of the invention relates to a sequence planning method for orthodontic arch wire bending with equiangular division, and 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.

Problems solved by technology

[0003] In the current process of bending orthodontic archwires by the orthodontic archwire bending robot (CN103892929A), due to the limitation of the robot structure, in order to improve the efficiency and bending accuracy of the robot bending orthodontic archwires, it is necessary to plan the orthodontic archwires in advance. The bending sequence of arch wire forming control points, while orthodontic arch wire has the characteristics of complex shape and large number of bending points, the existing orthodontic arch wire forming control point bending sequence planning methods mostly target a single forming control point , the planning efficiency is low, and the planning cycle is long. Obtaining a method to improve the planning efficiency of the forming control point bending sequence is a necessary prerequisite for realizing efficient digital bending of orthodontic archwires. At present, the orthodontic archwire bending technology field lacks orthodontic archwires. The method of bending sequence planning is difficult to achieve efficient digital bending of orthodontic archwires
