Personalized orthodontic appliance having orthoaxis function

Abstract

The present invention discloses an individualized orthodontic appliance with axis correction functions, comprising No. 1-7 individualized lingual brackets connected in series by an archwire. Each individualized lingual bracket includes a base plate and a bracket body connected with the base plate. In the No. 1-7 individualized lingual brackets, the underside of the bracket body of at least two of the individualized lingual brackets is disposed with a crimpable hook with a through hole and the through holes are connected in series by an ortho-axial wire. In this invention, the underside of the bracket body is disposed with the crimpable hook with the through hole and the ortho-axial wire is used to pass through the through holes. In this way, the underside of the bracket body can produce the corresponding orthodontic force while the crown of tooth is moving during the orthodontic treatment. The positions of the teeth roots can also be gradually corrected. It prevents teeth from inclining when they move far from the center; therefore the correction function is achieved. The structure of the individualized orthodontic appliance provided by the invention is simple and ingenious, the axis correction function is excellent and it is applicable to patients with dental extraction in the individualized orthodontic treatment.

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...

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
