Description

Orthodontic self-ligating bracket system with open auxiliary groove

Technical Field

The application relates to the field of orthodontic equipment, in particular to an orthodontic self-locking bracket system with an open auxiliary groove.

Background

It is often desirable in orthodontic treatment to selectively extract teeth to provide space, the resulting space being used to relieve crowding in the arch or for adducted anterior incisors. In most cases where tooth extraction is necessary, the most commonly extracted tooth is premolar, which has great significance in correcting malocclusion deformity because the removal of premolar has minimal effect on the morphology and function of the dental arch.

The orthodontic bracket is bonded on the lip side of the residual tooth after the premolar is pulled out, the orthodontic brackets are connected by using the arch wire to be used as a track for tooth movement, and various force-applying accessories are matched to generate correcting force to move the tooth to an ideal position and angle, so that the aims of aligning dentition and improving attractiveness and functions are fulfilled. However, in the process of controlling the tooth movement by matching the orthodontic bracket and the arch wire at present, the tooth movement is difficult to be accurately, safely and efficiently controlled.

When the incisor is used for internal cutting, a large clearance is reserved between the groove of the existing incisor bracket and the arch wire, and only a torque couple is applied to the arch wire for control. However, the current situation is that the torque couple is difficult to realize accurate control, the clearance cannot be eliminated due to the fact that the torque is reduced, the stress concentration of the incisor apical area is increased due to the torque, and the side effect of root absorption and shortening is often easy to occur, so that the correction effect and the long-term stability are influenced.

In the stage of aligning and leveling, the cuspid treatment is often inclined, the cuspid treatment is easily inclined after receiving the correction force of the remote movement, the arch wire can be driven to extend, incisors are extended outwards, the covering and deepening of front teeth have a lot of potential hazards, teeth can be caused to move back and forth, and the treatment effect and the treatment course of the whole orthodontic treatment are influenced.

When closing the tooth extraction gap, the archwire is typically bent into a rocking chair shape to counter the "roller coaster effect" when closing the gap so that the tooth roots on either side of the gap can move in parallel to close the gap. However, when the rocking chair-shaped arch wire is in place in the orthodontic bracket groove, overlarge friction force can be generated between the deformation position of the rocking chair-shaped arch wire and the corresponding orthodontic bracket groove, and in order to overcome the friction force, the correction force is inevitably required to be increased, but the overlarge correction force can cause the displacement of other teeth which do not need to be moved besides the increase of periodontal injuries.

At present, the problems exist objectively in the field of tooth orthodontics, in order to solve the problems, doctors can only adjust the bonding position of an orthodontics bracket, the bending adjustment degree of an arch wire, the correction force and the like according to personal experience at present, accurate, safe and efficient control over tooth movement is difficult to achieve, and risks, time and economic cost of patients are increased.
