Personalized orthodontic appliance having orthoaxis function

Abstract

The invention discloses a personalized orthodontic appliance having an orthoaxis function, which comprises No.1 to No.7 personalized orthodontic lingual brackets connected in series with each other by an arch wire. Each personalized orthodontic lingual bracket comprises a base plate and a bracket body portion connected with the base plate. Among the No.1 to No.7 personalized orthodontic lingual brackets, towing hooks with through holes are arranged on the lower sides of the bracket body portions of at least two personalized orthodontic lingual brackets, and the through holes are connected together in series through an axis correction wire. The towing hooks with the through holes are arranged on the lower sides of the bracket body portions of the personalized orthodontic appliance having the orthoaxis function, and the orthoaxis wire penetrates through the through holes, so that corresponding orthodontic force is produced on the lower sides of the bracket body portions while the dentalcrown moves in the orthodontic process, thereby gradually correcting the positions of the roots of teeth and avoiding the inclination of teeth in the distal movement process; therefore, the personalized orthodontic appliance has the orthoaxis function. Besides, the personalized orthodontic appliance is simple and smart in structure, good in axis correction effect, and thus suitable for dental extraction cases in personalized orthodontic therapy.

Description

technical field [0001] The invention relates to a personalized orthodontic appliance for orthodontics. Background technique [0002] Personalized orthodontic appliances, which have been used by more and more patients, have a series of personalized orthodontic lingual brackets (referred to as lingual brackets) connected in series through arch wires. Each lingual bracket The grooves are made according to the tooth types of the human oral cavity. Different tooth sizes are equipped with different lingual brackets. The structure of the lingual brackets includes the bottom plate that fits the teeth and the bracket that is integrated with the bottom plate. body. The classification of these tooth numbers is numbered according to the order in which the central incisor (front tooth) is tooth No. 1, and the second molar is tooth No. 7. Therefore, lingual brackets also have corresponding numbers from 1 to 7. [0003] In the field of orthodontic treatment, there is a tooth extraction c...

AI Technical Summary

Problems solved by technology

For labial orthodontics, the double groove system or positive axis spring is generally used to realize the positive axis function; but for lingual orthodontics, the bracket body is thin and inclined, and the prominence of premolars is generally higher than that of canines , so there will be a bend between the premolar and the canine, so that neither the double groove system nor the positive axis spring can be used

So far, personalized orthodontic appliances still do not have positive axis function
