Abstract

The invention discloses a dual-auxiliary-hole low-friction sliding self-ligating bracket. The self-ligating bracket comprises a bracket main body and an adhesive bottom board, wherein the bracket main body is arranged on the adhesive bottom board; the bracket main body is provided with an arch wire groove, a main ligation wing, an auxiliary ligation wing and a locking plate; the locking plate is respectively matched with the main ligation wing and the auxiliary ligation wing; the arch wire groove is formed between the main ligation wing and the auxiliary ligation wing; a locking plate slot matched with the locking plate is formed in the auxiliary ligation wing; a slot matched with the locking plate is formed in the main ligation wing; and an auxiliary hole is formed in the bracket main body. In the using process, a torque can be effectively controlled during extruding, and auxiliary traction can be carried out, the gap of the locking plate is opened on a primary arch wire, the auxiliary hole can be used for drawing crowed teeth to be aligned, and a secondary arch wire is put into the auxiliary hole, so that the two arch wires can be used for accelerating alignment, enables effective torque control and synchronously keeps the arc of teeth, and the tooth root can be effectively twisted to avoid the conventional root absorption situation.

Description

technical field [0001] The invention relates to a self-locking bracket, in particular to a low-friction sliding self-locking bracket with double auxiliary holes. Background technique [0002] At present, there are many self-ligating brackets on the market. These self-ligating brackets have complex structures, cumbersome operations, long treatment time, and few combined functions. , when severe crowding occurs, ordinary passive self-ligating brackets are often unable to align the teeth synchronously, and effectively control the torque of the crowded front teeth. If the torque is reduced, this is not a true alignment. During the orthodontic process, the self-ligating brackets without auxiliary holes will often lose the torque during the crowding of teeth. If the torque is well controlled Therefore, it can be concluded that self-ligating brackets have many disadvantages: 1. While aligning, it is easier to lose torque control; 2. Crowded cases are in the row. The traction cann...
