Description

{Self ligation orthodontic bracket assembly}

The present invention relates to an orthodontic bracket assembly, and more particularly, to an orthodontic bracket assembly that simplifies the operation mechanism of an arch wire for a dental orthodontic braid to improve orthodontic treatment, procedure efficiency, stability, To a calibration bracket assembly.

For example, orthodontic treatment for correcting an irregular tooth arrangement, such as malocclusion, usually uses an orthodontic brace, which is a mechanical assist device.

Until recently, various types and types of orthodontic appliances have been developed and used for orthodontic treatment. However, fixed orthodontic appliances are generally used, in which an arch wire is hung or pushed in a slot of a bracket attached to a tooth surface .

Conventional fixed orthodontic appliances have advantages such as ease of procedure for mounting brackets on the smooth outer surface of the teeth, while fixing the wires to the bracket requires a fixed, for example, elastic O-ring, bolt, Since it is necessary to tie the members to the brackets individually, it requires a great deal of time and effort, and has a disadvantage that the patient may feel pain easily.

Meanwhile, a self-ligation type bracket capable of fixing a wire by a so-called one-touch method is widely used to solve the disadvantage of a general fixed orthodontic appliance as described above, Japanese Patent Laid-Open Nos. 10-1541126 and 10-1506343.

 In short, the self-ligating orthodontic bracket assembly can be easily fixed and attached to a clip or cap, or a plate or a cover-like operation member, for example, by a one-touch operation without tightening the wire. Accordingly, the fixing member such as an elastic O-ring or bolt or clip for fixing the wire is excluded, thereby reducing the frictional force between the teeth, resulting in a relatively short calibration period and less pain and foreign body.

However, in the case of the conventional self-ligating orthodontic bracket assembly, the outer size is very small, but the structure of the operation member for wire bonding is very complicated, so that it is not easy to manufacture precisely, resulting in high manufacturing cost. There is a drawback and a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the technical background as described above and it is an object of the present invention to solve the problems of the background art described above, It can not be said to have been publicly known to the general public before.

The retainer 140 is a binding means for performing a complementary detachment function with the pin member 130 protruding from the bottom surface of the slide portion 113s of the bracket body 110 at a predetermined height.

2 and 3, the retainer 140 includes a circular plate 141h having a circular hole 141h formed in a center of a body 141 made of a plate-like elastic piece so as to be able to receive the pin member 130, And a slit hole 142s formed in the key hole 141s to form a passage through which the one side of the circular hole 141h is opened and the gap is expanded and contracted by the interference of the pin member 130, A pair of flow plates 141B extending from the circular plate 141A so as to protrude from the circular plate 141A and an arc-shaped long hole 141t formed as an escape groove communicating with the other side of the circular hole 141h, And a pair of elastic cushion ribs 141L formed in a wing shape so as to protrude inward at a boundary portion between the circular arc-shaped slots 141h and 141h.

6, when the ligation slide 120 is moved for opening and closing the slot 114, the pin member 130 is inserted into the flow plate 120 of the retainer 140, And is inserted in the slit holes 142s formed between the first and second slits 141B. At this time, the disc portion 141A is elastically deformed so that the gap of the slit holes 142s is spread by the interference of the pin member 130. [ The ligation slide 120 is inserted into or removed from the circular hole 141h of the circular plate 141A to receive or disengage the pin member 130 from the wire inserted into the slot 114, Lt; RTI ID = 0.0 > and / or < / RTI >

That is, the retainer 140 has a key seat formed at the center of a body 141 formed of a plate-like elastic piece, and is formed as a plate spring or a snap ring in the form of an arch or a horseshoe, A pin member 130 protruding at a predetermined height from a bottom surface of a slide portion 113s formed of a "concave" cavity in the second upper body 113 of the bracket main body 110 and a complementary desorption function The braid body 110 and the ligation slide 120 are coupled to each other through the bracket body 110 and the ligation slide 120, respectively.

That is, according to the self-ligating orthodontic bracket assembly 100 according to the present invention, the ligation slide 120 is set in a closed state to ligate a wire (not shown) inserted into the slot 114, When the pin member 130 is pushed into and inserted into the circular hole 141h of the circular plate 141A so that the elastic cushion 141L is inserted into the arc-shaped slot 141t So as to perform a brake function and a function. Accordingly, the ligation slide 120 can be pushed and closed to naturally absorb or substantially eliminate the impact generated when the arch wire ligation operation is performed.

Thus, according to the self-ligating orthodontic bracket assembly 100 of the present invention, it is possible to effectively relieve or completely eliminate the pain felt by a patient in the process of orthodontic correction using a conventional orthodontic bracket assembly .

Hereinafter, the operation of the self-ligating orthodontic bracket assembly 100 according to the present invention will be described in detail.

When the orthodontic treatment is performed using the self-ligating orthodontic bracket assembly 100 according to the present invention, the adhesive surface 111a forming the bottom surface of the base 111 of the bracket body 110 is attached to the tooth surface And an arch wire (not shown) is inserted into the slot 114 of the bracket body 110 in the tooth array direction to be seated.

When attaching the bracket body 110 to the tooth surface and setting it, the ligation slide 120 is set back to open so that the slot 114 is in an open state.

In the present invention, the treatment procedure for attaching and setting the bracket body 110 to the tooth surface is not limited to the present invention, and can be substantially the same as in the case of a conventional orthodontic treatment.

When the posterior end of the ligation slide 120 is lightly pushed by the orthodontist using a tool or a surgical tool to ligate the arch wire (not shown) inserted into the slot 114, the ligation slide 120 Shaped slide portion 113s provided on the second upper body 113 of the bracket body 110. [0064] As shown in FIG.

In accordance with such a sliding operation, the ligature slide 120 is closed to close the upper opening of the slot 114, thereby ligating the arch wire (not shown).

The retainer 140 provided on the bottom surface of the body 121 is fixed to the bottom surface of the slide portion 113s of the bracket body 110 by a pin May be set to the constrained and unlocked states to achieve locking and unlocking states by a complementary desorption action with the member (130).

That is, when the ligation slide 120 advances and slides to perform ligation operation, the pin member 130 is pushed into the circular hole 141h of the disc portion 141A of the retainer 140, . At this time, the shock absorbing elastic rib 141L is resiliently deformed toward the arcuate elongated hole 141t, so that the impact generated when the ligation operation is performed can be absorbed and relieved or alleviated. Thus, pain transmitted to the patient can be effectively excluded.

When the ligature slide 120 is set in a closed state to release the binding state of the arch wire inserted into the slot 114, the orthodontist inserts a tool or a surgical tool into the tool socket 112a, The ligation of the arch wire can be easily released as the upper side of the slot 114 can be opened by easily moving backward by the physical force pushing and pushing the ligation slide 120.

For example, by inserting the tip end of a tool or a surgical tool having a straight tip end portion into a tool socket 112a such as a flat screwdriver, and by gently rotating the tool socket 112a, the torque of the straight tip portion causes the ligation slide 120 The upper side of the slot 114 can be opened while being pushed backward. Accordingly, it is possible to provide the convenience of the procedure in which the ligation state of the arch wire can be easily and easily released by a so-called one-touch method.
