Description

Jig-integrated brace with tooth correction line}

The present invention relates to a jig-integrated orthodontic appliance having an orthodontic arc, and more particularly, a plurality of brackets fixed to the inner tooth surfaces of a plurality of orthodontic teeth, respectively, and the plurality of brackets are each coupled by a bridge and corrected The bracket is fixed to the orthodontic tooth by integrally forming a jig that is arranged to surround the upper part of the tooth and inserting an arc wire providing tension for teeth correction into the through hole formed in the bracket. The present invention relates to a jig-integrated orthodontic appliance having a tooth correction line that can achieve maximum orthodontic efficiency by reducing the deviation of the correction rate, which was influenced by the skill level of the operator, as well as improving the shortening and convenience.

Various methods provided as a means for correcting teeth include crooked teeth, protruding mouth, and surgical correction to surgically compensate for the maxillary and mandibular skeletal gap, and these methods are widely used for the purpose of restoring balanced facial features and functions. It is used, and various devices and methods are used depending on the cause or treatment time. For example, the upper and lower jawbones can be classified into devices that inhibit or enhance the development or devices that gradually move the teeth to a desired position.

In addition, it can be classified into removable devices that can be installed and removed in the oral cavity and fixed devices that are attached to the teeth and removed at the end of treatment.

Meanwhile, as one of the methods for correcting teeth, there is an orthodontic method using a double bracket.The orthodontic method using a double bracket uses a property that moves when the tooth receives an external force, and attaches the bracket to the tooth and corrects it. It is a fixed type therapy that gradually moves teeth by using the tension of a wire such as a dragon wire or a rubber band, and is commonly used in various types of orthodontic treatment.

Looking in more detail, each bracket is firmly attached to the surface of the tooth to be corrected, a wire is fixed to interconnect the brackets, and the tension of the wire is adjusted to variously control the direction and strength of the force applied to the wire. As a result, the tooth to be corrected is gradually moved. Therefore, the orthodontic treatment is performed by gradually moving the tooth to be corrected while its position and posture are changed by the tension of the wire.

The conventional orthodontic method using the bracket made as described above greatly changes the orthodontic efficiency according to the experience of the operator. First, in the process of fixing the bracket to the orthodontic tooth, the tension of the wire must be accurately fixed at the center of the orthodontic tooth. It can act accurately, but since the fixing position of the bracket is changed according to the ability of the operator, the tension of the wire does not work correctly, and there is a problem that the orthodontic position of the orthodontic tooth is displaced from the designed position.

In addition, according to the experience of the surgeon, the wire is pulled or loosened while adjusting the tension while finely adjusting the dentition, but there is a problem in that the patient's discomfort and pain are increased by the repetitive tension adjustment process of the wire.

In addition, in the conventional bracket, brackets are individually molded to correspond to each of the orthodontic teeth, and after fixing the molded bracket to the orthodontic teeth with an adhesive, the wire is bonded to the bracket, and the combined wire is tightened or loosened to increase tension. It consists of a process of adjusting.

In the correction method using a bracket made through the above process, there is a problem in that the time required for the procedure is determined by the experience and ability of the operator in all processes, and the discomfort and pain of the person being treated increase.

In addition, while teeth are generally flat on the labial side, the lingual side has a lot of curvature and a wide variety of morphological variations. Conventional brackets have a lot of curves and are very difficult to fix on the tooth surface of the lingual side with very diverse morphological variations. It is difficult, and even in a fixed state, there is a problem in that food is caught in the gap by generating a gap between the tooth surface, and furthermore, there is a problem that the position of the bracket is twisted or displaced during the correction process, causing a negative effect on the treatment result.

Therefore, in the field, in the orthodontic method using a double bracket, the correction efficiency does not depend on the experience or ability of the operator, and there is an urgent need for a bracket that can shorten the time required for the procedure while increasing the correction efficiency.

Does not.

Hereinafter, a preferred embodiment of a jig-integrated orthodontic appliance having a tooth orthodontic arc according to the present invention will be described with reference to the accompanying drawings.

First, the jig-integrated orthodontic appliance 1 having a tooth orthodontic arc according to the present invention is a jig 10 that surrounds and couples the upper portions of a plurality of orthodontic teeth arranged adjacent to each other as shown in FIGS. 1 and 2. ), a plurality of brackets 20 each fixed to the inner tooth surface of the plurality of orthodontic teeth and having a through hole 21 penetrating in the longitudinal direction of the jig 10, and the plurality of brackets 20 The bridge 30 connecting the jig 10 and the arc wire 40 which is inserted through the through holes 21 respectively formed in the plurality of brackets 20 to provide tension for correcting the position of the orthodontic tooth Including, the jig 10 and the bracket 20 are integrally molded by the bridge 30, where the arc line 40 is pre-inserted into the bracket 20 for orthodontic teeth By being combined with the procedure, it is possible to minimize the discomfort and pain of the non-operator by minimizing the time required for the procedure, and further, there is an effect of maintaining a constant correction efficiency, which was influenced by the experience and ability of the operator.

Looking at this in detail with reference to the accompanying drawings, first, the jig 10 surrounds and couples the upper portions of a plurality of orthodontic teeth T arranged adjacent to each other, and extends in the longitudinal direction and is an orthodontic tooth ( A fitting groove 11 is formed that fits on the upper surface of T).

Here, the jig 10 and the fitting groove 11 formed in the jig 10 are formed to correspond to the position and shape of the orthodontic tooth, and the length and shape of the jig 10 and the fitting groove 11 are After the orthodontic tooth is photographed through an imaging device such as an X-ray or a scanner, it is determined by a result value calculated by reading it through a reading program.

Looking at this in more detail, the fitting groove 11 is formed in a shape matching the characteristic mastication surface shape of the orthodontic tooth, and the mastication surface of each orthodontic tooth is fitted in a shape matching the fitting groove 11, which will be described later. The convenience of the procedure for fixing the bracket 20 to the tooth surface of the tooth and the time required for the procedure can be shortened, which will be described in detail in the description of the bracket 20 to be described later.

On the other hand, the photographing apparatus and the reading program are well known used in the conventional orthodontic method, and detailed illustrations and descriptions in the present invention will be omitted.

The jig 10 is a characteristic structure of the present invention and has the following differences from the jig constituting the conventional bracket for correcting teeth.

First, the jig 10 of the present invention is made so that one jig 10 is coupled to the entire plurality of orthodontic teeth, and the conventional jig is made to be individually coupled to a plurality of orthodontic teeth.

Due to this difference, since the treatment process of the jig 10 of the present invention is completed by only coupling once to the orthodontic tooth, the treatment time is relatively short compared to the treatment time required for combining the conventional jig to each orthodontic tooth. The jig 10 can be coupled to the orthodontic tooth.

On the other hand, the material, thickness, and width constituting the jig 10 can be changed due to reasons such as the condition of the orthodontic teeth and the time of correction, and are not limited to the shape shown in the drawings, and are harmless to the human body and processed. Of course, various materials can be used as long as this is possible.

The bracket 20 is fixed to the inner tooth surface of the orthodontic tooth through an adhesive, and is disposed at a position spaced apart from each other along the length direction of the jig 10, and a position corresponding to each of a plurality of orthodontic teeth individually Is placed in

The bracket 20 is fixed to the inner tooth surface of the orthodontic tooth so that the tension provided from the arc 40 to be described later acts on the orthodontic tooth, and is fixed to the inner tooth surface of the orthodontic tooth through an adhesive and can be corrected. It is removed after completion.

Here, the shape and size of the bracket 20 are changed according to the shape of the orthodontic tooth, but preferably, one surface that contacts the tooth surface of the orthodontic tooth has a flat plate shape as a basis, but corresponds to the shape of the abutting tooth surface. Transformed into shape.

That is, the area in contact with the tooth surface of the orthodontic tooth is increased so that the fixed position is not displaced, but the gap between the bracket and the tooth surface is prevented from occurring, thereby preventing food from being caught in the gap.

On the other hand, the bracket 20 has a through hole 21 formed through the lengthwise direction of the jig 10, that is, along the direction in which orthodontic teeth are arranged, and the through hole 21 has an arc line 40 to be described later. ) Is inserted.

A plurality of brackets 20 made as described above are formed to individually correspond to a plurality of orthodontic teeth, and are coupled to one jig 10 through a bridge 30 so that the jig 10 is attached to the upper portion of the orthodontic tooth. By fitting to the surface, a plurality of brackets 20 can be placed at the designed position of the orthodontic tooth.

Through this, the bracket 20 of the present invention can save a relatively time required for the procedure compared to the process of fixing a plurality of brackets independently molded to correspond to each of the conventional orthodontic teeth with an adhesive. As described above, since the jig and bracket are formed by scanning the position and shape of the orthodontic tooth, simply by combining the jig to the upper part of the orthodontic tooth, the bracket can be placed at a predetermined position on the tooth surface of the orthodontic tooth. Since it can be disposed, it is possible to minimize the change in correction efficiency according to the fixing position of the bracket, which was influenced by the experience or ability of the operator.

In addition, the bracket 20 is abutted to the tooth surface of the orthodontic tooth in a state coupled to the jig 10 and then adhered by an adhesive. At this time, each bracket 20 is attached to the orthodontic tooth before fixing with the adhesive. There is an advantage in that it is easy to check whether it exactly matches the specified position on the tooth surface of the tooth.

Conventional brackets are independently molded as described above, so the operator directly moves the bracket to match the expected position before fixing to the tooth surface of each orthodontic tooth, and marks the matched area through a marking means or immediately applies an adhesive. It is bonded through. However, the conventional bracket and the method of treating the same increase the time required for the process of bonding each bracket to the orthodontic tooth, causing discomfort and pain for the patient to be treated, as well as connecting each bracket to change the tooth position. There is a problem in that the calibration efficiency is deteriorated as the arcs providing tension are arranged in an oblique line.

In other words, in the conventional bracket, the adhesive position of the bracket is determined by the experience or ability of the operator, so the arc line cannot be horizontal even by a slight change in position and is arranged diagonally to the top or bottom, and the tension acts in an unintended diagonal direction. While doing so, there is a problem in that the calibration efficiency is poor or cannot be displaced to the designed calibration position.

On the other hand, in the bracket 20 of the present invention, in a state in which a plurality of brackets 20 are coupled to one jig 10 by a bridge 30 to be described later, the bracket ( 20) can be correctly positioned at the designed position, and the bracket 20 can be fixed using an adhesive after final confirmation of the bonding position while moving the bracket 20 up and down using the bridge 30 before bonding. In addition to shortening the time required for the process, the arc line inserted into the through hole 21 formed in the bracket 20 can be maintained horizontally, thereby increasing the working efficiency of tension, that is, the calibration efficiency.

The bridge 30 connects the jig 10 and the bracket 20, and the bracket 20 is integrally coupled to the jig 10, but the bracket 20 is an adhesive on the tooth surface of the orthodontic tooth. After being fixed by, it is cut from the bracket 20 through a cutting device such as a dental drill.

The bridge 30 is not limited to the shape and number shown in the drawings, and can be variously changed according to the shape and size of the bracket 20.

The arc line 40 is inserted through the through hole 21 formed in the bracket 20 to integrally connect a plurality of brackets 20 and push the bracket 20 using a tension formed through an elastic restoring force. By pulling, the position of the fixing tooth to which the bracket 20 is coupled is displaced.

This line 40 is a line inserted into the through hole 21 before the bracket 20 enters the oral cavity of the person to be treated. This is a relatively procedure compared to connecting a plurality of brackets using a conventional line. It has the advantage of reducing the time required for treatment and does not cause discomfort and pain for the recipient.

Looking at this in more detail, in the conventional arc line, since the arc line is inserted into the fixed bracket after the bracket is individually adhered to the orthodontic tooth, the recipient must keep the mouth open throughout the procedure of inserting the arc line. It is difficult to connect the arc wire to the bracket because the position of the orthodontic teeth is uneven and the arc line has a high elastic force to form tension when connecting multiple brackets using a single arc line. There was this.

On the contrary, since the arc wire 40 of the present invention is coupled to the through hole 21 formed in the bracket 20 before the bracket 20 is coupled to the orthodontic tooth, the bracket 20 is attached to the tooth surface of the orthodontic tooth. At the same time as coupled to the position of the line 40 is also set.

Therefore, compared to the prior art, the treatment process can be reduced, thereby minimizing the treatment time, thereby reducing the discomfort and pain of the person being treated.

In addition, even if the arc line is deformed convex or concave according to the position of the orthodontic tooth, the horizontal can be maintained, so that the direction of action of the tension provided by the arc line can be guided to the designed direction, thereby maximizing the correction efficiency.

On the other hand, the jig 10 has a stabilizer for preventing a stepped jaw from occurring between the orthodontic tooth and the comparison tooth disposed adjacent to the orthodontic tooth when the position of the orthodontic tooth is corrected by the tension of the arc line 40 50 is further provided, wherein the stabilizer 50 is provided at both ends in the longitudinal direction of the jig 10, is connected by the jig 10 and the bridge 30, and is the highest among the orthodontic teeth. A first region 51 fixed to the tooth surface of the orthodontic tooth disposed outside, and a second region 52 connected to the first region 51 and fixed to the tooth surface of the comparative tooth.

The stabilizer 50 made as described above is to solve the problem that a stepped jaw is formed between adjacent comparative teeth when the position of the orthodontic tooth T is displaced by the tension of the arc line 40.

The stabilizer 50 is composed of a first region 51 fixed to the tooth surface of the orthodontic tooth and a second region 52 connected to the first region 51 and fixed to the tooth surface of an adjacent comparative tooth. .

The first region 51 and the second region 52 are formed to surround the tooth surface of a fixed orthodontic tooth or a non-fixed tooth, and are fixed to the orthodontic tooth or the non-fixed tooth through an adhesive.

Here, the portion where the first region 51 and the second region 52 are in contact with each other is formed to have an elastic restoring force, so that even if the position of the first region 51 is displaced, the second region 52 becomes the first region 51 By limiting the degree of displacement, it is possible to prevent the occurrence of a stepped jaw between the orthodontic tooth and the comparative tooth.

Meanwhile, the number of the second regions 52 may increase as the overlapping of orthodontic teeth or comparative teeth increases. In particular, when the overlapping of the orthodontic teeth with the adjacent comparative teeth is severe, the second region 52 Increase the number of ).

This is because if there are orthodontic teeth with severe overlapping, a strong tension acts on the orthodontic teeth to correct them, and this causes a severe change in the position of the orthodontic teeth, which can form a stepped jaw between the teeth and the comparative teeth. When tension is applied, the number of the second regions 52 is increased to prevent the first region 51 from being displaced beyond the designed position, thereby preventing the formation of a stepped jaw between the orthodontic tooth and the adjacent non-orthodontic tooth. .

As described above, in the present invention, specific matters such as specific components, etc., and limited embodiments and drawings have been described, but this is provided only to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , If a person of ordinary skill in the field to which the present invention belongs, various modifications and variations are possible from these descriptions.

Therefore, the spirit of the present invention is limited to the described embodiments and should not be defined, and all things equivalent or equivalent to the claims as well as the claims to be described later belong to the scope of the spirit of the present invention. .
