Description

Stacked double-groove bracket

Technical Field

The utility model belongs to the field of medical equipment, relates to an orthodontic component, in particular to a superimposed double-groove bracket used for fixing an appliance.

Background

In the orthodontic treatment, the common appliance comprises a fixed appliance and a transparent appliance, wherein the fixed appliance has a plurality of different structural forms, and mainly comprises a square wire appliance and a straight wire appliance. The square wire appliance is designed in 1928 as a basic appliance, and the straight wire appliance is a square wire appliance, is designed in the early 70 th of the 20 th century and is improved by multiple scholars later. Nowadays, the straight wire appliance is also the most used appliance at present.

At present, a fixed orthodontic device mainly comprises a bracket, an orthodontic arch wire and accessories, and although the fixed orthodontic device has various different structural forms, the fixed orthodontic device is mainly characterized in that the structure of the bracket is changed, for example, a Tip-Edge bracket (formally published in 1987) applied to a differential straight wire orthodontic device combines the concepts of a Begg bracket and a straight wire bracket, so that teeth can obliquely move and have the functions of the straight wire bracket. No matter how the bracket used for fixing the appliance is improved and deformed, the structural form of the appliance is that the bracket designed by the first generation appliance (the square wire appliance) is a blue book, and the appliance adopts a single-groove form and can not be integrated in multiple directions and multiple functions, for example, the differential straight wire appliance has the following defects:

first, vertical tooth problem: Tip-Edge brackets allow the teeth to tilt, but later on they are time consuming to erect with Tip-Edge brackets: the vertical clinical operation of the positive shaft spring is relatively complicated; when the transverse pipe is inserted into the nickel-titanium wire vertically, if the nickel-titanium wire is thin, the vertical force is weak, and if the nickel-titanium wire is thick, the nickel-titanium wire is difficult to be in place, and the bracket is easy to fall off.

Secondly, the problem of torque control: because the opposite angles of the groove are provided with the wedge-shaped triangular blocks, the arch wire is not easy to cling to the groove wall of the groove during torque control, the torque of the tooth root can be controlled only by matching the positive shaft spring, the operation is more complicated, and the root control effect is slower.

Thirdly, anchorage problem: Tip-Edge differential straight wire arch correction techniques typically use stainless steel wires manufactured by a.j.wilcox corporation. The hardness and elasticity of other arch wires are different, the correction effect is different, sometimes the arch wires are not easy to open and bite, sometimes the anchorage molars are easy to lean backwards. In the Tip-Edge differential straight arch correction technology, when the tooth extraction gap is closed in a tooth extraction case, the molar is easy to move towards the middle (forwards), and sometimes the anchorage molar is elongated to a certain degree. Therefore, anchorage is required to be reinforced.

And fourthly, because the Tip-Edge differential straight wire appliance is mainly imported, the Tip-Edge differential straight wire appliance is not widely applied in China at present and is relatively expensive.
