The self-locking bracket is a new technology in recent years, which brings revolutionary change to fixed orthodontic technology.
To make orthodontics more convenient.
Its main advantage is that it can greatly reduce the friction resistance between the wire and bracket.
Because it has a door on the bracket, the orthodontic wire can be directly locked in the groove of the bracket, eliminating the binding of the ligating wire or rubber band on the orthodontic wire.
1. The slide bracket is similar to the “buccal tube” in the state of self-ligation, and the self-locking structure corresponding to the bottom of the groove is a metal outer arm with little elasticity, which can open or close the groove by sliding and pulling or rotating in the gingival synaxial direction.
When opened, the bow wire is allowed to be incorporated into the groove, and when closed, the metal slide is formed, which limits the release of the bow wire and does not impose ligation force on it.
This bracket is mainly through the deformation of high elastic alloy arch wire (such as NiTi wire) to generate the orthodontic force to control the three-dimensional position of the tooth.
Numerous studies have found that because the groove is turned off a smooth hard metal chute, and such braces allow teeth along the arch wire sliding process in a certain degree of tilt, even using coarser arch wire can stay small in sliding friction, the friction not only significantly less than traditional treatments, but also lower than the self-locking braces of treatment for spring clip type.
2. The self-locking of the spring clamp bracket is completed by the spring clamp with better elasticity.
As a self-locking structure of the bracket, the spring clip can lock the arch wire into the bracket and interact with it due to its good elasticity to provide continuous and gentle torsional force and torque force to the tooth.
This method relies on highly elastic spring clips for energy storage and expression, combined with various angles preformed by elastic arch wires and brackets to achieve three-dimensional tooth position control, which is a major feature that neither traditional appliances nor slide type self-locking brackets appliances have.
