Description

The present invention relates to a self-ligating bracket. In more detail, the present invention forms a body portion and a base portion, which are constituents of a bracket attached to a tooth, using an elastic material, and a wire is self-ligated to a recess. Regarding the brackets that are.

There are many treatments for aligning and correctly orthodontic teeth that are misaligned. Two basic orthodontic procedures are commonly used.

Such orthodontic techniques include a lightwire technique and an edgewise technique.
The lightwire technique corrects each tooth with a different force to secure the bracket to all teeth, including the molars, and align the teeth with the arch wire that looks round in the cross section. And calibrate.

The archwire is loosely secured to the bracket, untied with a band, minimizes friction, and allows the tooth in contact at one point to slide, rotate, tilt, and twist freely.

In particular, italics, twisting and rotation require appropriate auxiliary equipment.

The edgewise technique is currently the most widely and commonly used orthodontic technique. In the initial stage, by using an arch wire with a circular cross-section, the flexible round arch wire allows the tooth in the wrong place to move over a wide range with less force.

The Arch Wire is constructed into a metal band or elastic band or other suitable form of holding mechanism by being inserted into a slot formed in a bracket attached to all permanent teeth, including molars. ..

Patent Document 1 is a patent registration publication of an invention relating to an "orthodontic bracket".

Referring to FIG. 1, in the invention described in Patent Document 1, in a bracket in which a ring or a ligation wire fixes an arch wire as an orthodontic bracket and corrects a tooth arrangement, the arch wire (5) is in the center. A body portion (6) having a first slot portion inserted into the portion and having a short contact area and a second slot portion into which the ring (6) or a ligation wire is inserted, each having a small cross-sectional area and forming a round at a protruding corner ( 3), the base portion (2) which is adhered and fixed to the surface of the tooth and has a bottom surface having a wide cross-sectional area and forms a round at the protruding tip portion, and the base portion and the body portion are integrally connected to the above. A home into which a ring and a ligation wire are inserted and fixed. The configuration includes a connection formed on the entire side surface.

Further, Patent Document 2 is a patent registration publication of an invention relating to "a bracket for orthodontic teeth".

Referring to FIG. 2, the invention described in Patent Document 2 is an orthodontic bracket for teeth, and a wire (5) for applying a force to the teeth to move the teeth to a desired position is attached to the teeth. By doing so, it is composed of a bracket body part (3) and a detachable attachment means (2), the wire (5) is fixed to the bracket body part (3), and the bracket body part (3) is made of a synthetic resin material. It is composed of a single columnar shape having a semi-circular cross section as a whole, and a housing ball (7) penetrating one surface of the cross section and the other surface of the opposite surface of the cross section is formed.

These receiving balls (7) have a cross-sectional size corresponding to that of the wire (5), and if the line (5) is housed through the receiving ball (7), its bracket body portion (3). ) Will be fixed in position.

The detachable attachment means (2) is coupled to the bracket body portion (3) and detachably attached to the tooth surface, and specifically, it is desirable that the first suction cup is made of a flexible material.

The material of such removable attachment means (2) can be any material that is supple but has good elasticity, but the configuration is disclosed by using a material such as rubber, for example.

FIG. 3 is a diagram showing an example of using an arch wire using a bracket.

In the invention described in Patent Document 1, a ring and a ligature are projected while fixing an arch wire and a bracket, and are connected to a lip portion to be visually exposed to another person, causing discomfort, food and drink, and the like. There is a problem that it is not hygienic because it gets caught in foreign matter.

Further, it is difficult to separate the ring and the ligature wire that have been inserted into the slot portion for a long time, the area where the slot portion and the arch wire contact is wide, and there is a problem that frictional resistance is generated.

In addition, there is a problem that the ring and the ligature wire for fixing the arch wire are colored with the passage of time, which causes visual disgust and discomfort to the other party.

In the invention described in Patent Document 2, the detachable attachment means and the bracket body portion are configured separately, which is complicated to manufacture and assemble. The ball for accommodating the bracket body portion, the detachable attachment means, and the bracket body portion. There is a problem that it is not hygienic because foreign substances such as food and drink are caught in the joint part of the.
