Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental bracket for orthodontic treatment and a dental orthodontic appliance using the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dental apparatus applied to a dental orthodontic treatment, and more particularly, to a dental bracket fixed to a tooth to support a wire for orthodontic treatment and defining a limit position of the wire.

For modern people, the appearance, especially the impression, acts as a criterion for judging people when interviewing for employment or entrance, and also plays a very important role in social life, such as occupying a large part in interpersonal relationships. Especially, It becomes a factor which influences the whole. As a result, orthodontic treatment for the improvement of teeth, teeth, or facial skeleton is performed along with plastic surgery.

The dental orthodontic treatment is a concept that includes correcting dentition, for example, orthodontic correction that aligns crooked teeth. It corrects various skeletal mismatches that can occur during the growth process and can perform normal functions And contributes to healthy oral tissues. Further, it can change the anatomical structure of the oral cavity to make a face line and make a beautiful face image.

The orthodontic treatment includes orthodontic treatment for improving the dentition such as malocclusion through progressive movement of the dentition, growth correction for promoting or suppressing the appearance of the facial skeleton in the growing period, surgical treatment for the facial skeleton, And orthognathic surgery to give skeletal improvement by performing the surgery.

In other words, it is impossible to treat with the simple tooth movement because the abnormality of the lower teeth and the facial skeletal structure, especially the jaw structure, are too severe. In such cases, Growth Modification. In adults, moderate to severe skeletal anomalies are also used in conjunction with the above-mentioned treatments for orthognathic surgery in which functional and / or aesthetic faces are corrected by correcting abnormalities of the jaw itself.

The orthodontic treatment can be broadly divided into a straight side correction and a lingual correction. The straight side correction is a technique in which a correcting mechanism used for orthodontic correction is attached to the surface of the lips (the outer surface of the teeth) And the lingual correction is a correction method in which the orthodontic appliance is attached to the surface of the tooth (Lingual) (the inner surface of the tooth) of the tooth to perform orthodontic correction.

Examples of the calibration mechanism include a calibration wire for realizing movement of a tooth and a wire supporter (generally referred to as a 'bracket') for supporting the calibration wire, and the bracket (dental bracket) Or lingual surface of the tooth. The bracket is provided with a plurality of teeth along an array direction of dentitions, and the orthodontic wire is coupled to the bracket.

The orthodontic treatment may take a long period of time depending on the condition of the patient. Examples of the dental orthodontic treatment include improvement of dentition of the anterior teeth or interposition of the anterior teeth, improvement of the stone entrance and removal of the teeth, And so on.

On the other hand, in the orthodontic orthodontic treatment, the correction for moving the teeth of the anterior portion to the lingual side, for example, the palatal side is referred to as lingual pulling, and in the case of the protruding teeth of the patient abnormally protruding forward, , And the lingual traction described above is presented as one method for correcting such a stone entrance and exit. In addition, the anterior teeth are spread to the lingual side even during orthodontic treatment with anterior crowding.

In the case of the above-mentioned orthodontic treatment, since the anterior portion is pulled backward and the wire passes through the three brackets of the posterior portion, the frictional force between one of the three devices (bracket) The movement is stopped, and lateral movement of the anterior and posterior portions occurs, which can remarkably increase the treatment period.

In order to perform various dental orthodontic treatments for the purpose of treatment described above, a dental orthodontic appliance including a wire for orthodontic treatment and a bracket for the purpose of treatment is installed inside the oral cavity of the patient, and a wire for orthodontic treatment is also moved along with the movement of the teeth . As a result, soft tissue in the oral cavity is injured and injured by the tip of the orthodontic wire, causing the operator to approach the distal end of the orthodontic wire with a dental tool, such as a distal end cutter The structural characteristics of the oral cavity and the orthodontic appliance installed in the oral cavity deteriorate accessibility, resulting in difficulties in the procedure, and in particular, side effects such as dropout of the device components.

As a specific example, in the orthodontic orthodontic procedure for pulling the teeth of the anterior portion backward, the wire moves backward along with the backward movement of the anterior portion. In this process, the rear end of the wire stimulates the buccal mucosa. In order to prevent this, the operator has to cut the rear end of the wire regularly or irregularly. However, due to the structural characteristics of the oral cavity and the orthodontic appliance installed in the oral cavity, Or there is a risk that the treatment will be prolonged due to the dropout of the device as described above.

Accordingly, the present inventors have developed a wire supporter that performs a function of limiting a movement of a wire used in a calibration procedure, that is, a wire for calibration, and a mechanism for supporting the wire, and a tooth correcting device having the wire supporter .

The orthodontic appliance includes a wire wire 310, an anterior bracket 10 and a canine bracket T3 200 and a guide wire 400 and a posture bracket 100. A pulling member 500 of an elastic material such as a rubber band or a spring is applied for pulling the wire wire 310.

The arsine wire 310 has an arch shape so as to be disposed along the teeth of the anterior portion. The front bracket 10 is fixed to the incisors for mounting the arsine wire 310 to the front portions T1, T2 and T3 and is fixed to the surfaces of the incisors to support the arsine wire 310 do. Generally, anterior teeth means teeth corresponding to central teeth, lateral teeth, and canines.

The canine bracket is a bracket that is directly or indirectly connected to the arc wire 310 so as to be disposed on one side of the canine T3, for example, a net side. The guide wire 400 is slidably inserted into the canine bracket and the tip of the guide wire 400 is exposed in front of the canine bracket through the canine bracket T3 200, The rear end of the wire 400 is fixed to the retainer bracket 100.

The canine bracket (200 of T3) is a bracket or guide bracket for slidably supporting the guide wire (400). For example, the guide bracket (200) described with reference to FIGS. 10 to 12 is attached to the canine bracket Lt; / RTI >

The first and second embodiments of the present invention will be described with reference to the accompanying drawings. The present invention is not limited to the above-described embodiments, and various changes and modifications may be made without departing from the scope of the present invention. The guide wire 400 is used as a posture bracket of the orthodontic appliance, and restricts the backward movement of the guide wire 400. Of course, other embodiments of the above-described dental bracket, for example, the second to fourth embodiments 100A to 100C, may also be applied to the mouth bracket of the orthodontic appliance according to the present embodiment.

In the present embodiment, the posterior tooth bracket 100 is fixed to the tooth surface of the foremost rear tooth among the left posterior tooth and the most rear tooth, for example, the seventh tooth (second molar).

The other molar teeth (left and right teeth 6 in the present embodiment) located in front of the molar teeth (left and right teeth 7 in this embodiment) to which the molar bracket 100 is applied among the left molar teeth and the right molar teeth, A separate guide bracket 200 to which both sides of the wire 310 are slidably inserted can be applied. Hereinafter, the guide bracket 200 applied to the left and right canines T3 will be referred to as a first guide bracket, and the guide brackets applied to the left and right molars, for example, the first molar T6 will be referred to as a second guide bracket.

The guiding brackets or second guiding brackets 200 applied to the left and right molar portions are respectively provided on both sides of the arbor wire 310 and support both sides of the arbor wire 310, As shown in Fig.

Next, the guide wire 400 extends from the left and right eccentric brackets 100 to both sides of the arced wire 310 through the second guide bracket T6 so as to guide the rearward movement of the anterior portion. Therefore, the guide wire 400 overlaps with both sides of the line wire 310.

The guide wire 400 passes through the second guide bracket 200 and is slidably inserted into the guide bracket of the canine T3, that is, the first guide bracket T3.

The traction member 500 is configured to provide a traction force to the line wire 310 for rearward movement of the forefingers T1, T2 and T3. The traction member 500 is provided at one end (front portion) And the other end (rear portion) of the pulling member is connected to the hook (rear hook) 240 of the second guide bracket.

According to the above-described orthodontic appliance, that is, the orthodontic system for realizing the rearward movement of the anterior portion, the frictional force acting on the orthodontic wire (wire wire, guide wire) upon pulling of the anterior portion is reduced and the tooth collapse during the orthodontic treatment can be prevented And the damage of the soft tissue in the oral cavity by the wire can be prevented.

When the forward portions T1, T2, and T3 are gradually moved backward by the above-described pulling member 500, the canine bracket, that is, the first guide bracket (T3 200) also moves backward. Since the rear end of the guide wire 400 is forwardly supported by the mouthpiece bracket 100 when the anterior portion is moved backward, the distal end of the guide wire 400 is gradually moved toward the front of the canine bracket T3 And protrudes long.

In this process, the guide wire 400 guides the backward movement of the anterior portion and provides a reaction force to the anterior portion of the retraction member 500 so that the teeth do not collapse. At the same time, both ends of the line wire 310 move backward through the second guide bracket (T6)

The operator cuts both ends of the wire wire 310 and the distal end of the guide wire 400 according to the moving distance of the anterior portion to prevent damage to the soft tissue and the occurrence of inflammation, Since the distal end of the guide wire 400 is exposed to a portion where the dental cutter is easily accessible, the operability is improved and the burden on the patient is reduced.

It is a matter of course that the orthodontic appliance described in the present embodiment is a pure-toe orthodontic appliance and an example of the orthodontic appliance is provided in the lower teeth, but it can also be applied to the correction of the upper teeth.
