Method for producing dental orthodontic supporter groove

Abstract

The invention discloses a making method of dental pincushion distortion tray groove, which comprises the following steps: rolling die; doing cold drawing; squeezing to form bar-shaped fine blank of pincushion distortion groove; manufacturing the fine blank into arch wire trench; cutting into individual product.

Description

technical field [0001] The invention relates to a production method of a dental orthodontic bracket body for dental orthodontics. Background technique [0002] Dental orthodontic brackets are equipment for orthodontics, and are key components of fixed orthodontic appliances. Its structure is shown in Figure 1 and Figure 2. For the correction of tooth deformity, usually several brackets are bonded to a row of teeth, and the arch wire is embedded in the arch wire groove 2 of each bracket body 1. In the process, the ligature wing of the bracket body is used to fix the dental arch wire on the bracket with the ligature wire, and the dental arch wire exerts various types of correction force on the teeth through the bracket, and gradually corrects the deformed teeth, thereby To achieve the purpose of orthodontics. [0003] For dental orthodontic brackets, the main problems to be solved are surface roughness (required Ra≤1.6μm) and precision. Only when the surface is smooth, can ...

AI Technical Summary

Problems solved by technology

Due to the influence of shrinkage instability and other factors in the casting process, the bracket body processed by casting method also has the problems of rough surface and difficult to guarantee the accuracy of external dimensions

Therefore, the surface roughness and precision of the brackets processed by these methods cannot meet the clinical requirements, and the processing procedures are complicated, the cost is high, and the production efficiency is low.
