Description

The orthodontic bracket attaching device {the labial bracket attaching jig for orthodontics}

The present invention relates to an orthodontic bracket attachment device for accurately attaching the bracket used for orthodontics not only to the tooth surface, that is, the front tooth (front tooth), but also to the posterior part (molar tooth) inside the mouth. It relates to an orthodontic bracket attachment device that supports the bracket to be correctly positioned and attached to the tooth surface.

In general, the most important step in the field of orthodontic treatment to restore the aesthetic, pronunciation, chewing function of the teeth by arranging the teeth is to attach the bracket to the specific part of the teeth quickly and accurately, The bracket can be positioned at one height. The orthodontic wire that provides elasticity to move the teeth is inserted into the slots of the well-attached brackets, thereby transmitting the fixing force to the teeth, thereby allowing the desired tooth movement.

On the other hand, orthodontic treatment is mainly performed by orthodontic treatment performed by attaching the bracket to the labia (outside lip or cheek) and lingual orthodontic treatment by attaching the bracket to the invisible lingual lingual side. In both the orthodontic treatment and the lingual orthodontic treatment, the attachment process and the attachment mechanism are very important.

The correct position of the bracket during orthodontic treatment is based on the proper height and angulation (slope of the root of the tooth (left and right)) and torque (slope of the teeth (front and rear) of the tooth). ), Rotation (the degree of rotation of the tooth mounting criteria) must be accurately reproduced in three dimensions to ensure good orthodontic treatment.

The instruments used for orthodontics include a bracket for orthodontics, a tweezer for holding the bracket and attaching it to a tooth, and a gauge for measuring the height of the bracket. do.

The bracket 100 used in orthodontics is mounted on both sides of the stem 101 and the front part of the stem 101 as shown in FIG. 1A, and the slot 102a is inclined by a predetermined angle at the center thereof. Is formed and the upper and lower portions are formed to be bent and the tie wing 102 and the locking function, the wire 103 is inserted into the slot 102a of the tie wing 102 to provide orthodontic force, and the one side tie wing ( The identification mark 104 for marking the upper and lower positions of the bracket on the upper surface of the 102 to enable the operator to recognize, and the fixing piece 105 is provided over the tie wing 102 to provide a fixed force to the wire 103 It consists of.

In addition, as shown in FIG. 1B, a tube 110 for finishing the wire is attached to an end molar part inside the oral cavity, and the tube 110 has a hole 110a through which the wire penetrates in a longitudinal direction. have.

When the bracket 100 and the tube 110 configured as described above are adhered to the tooth surface, the orthodontic force exerted from the orthodontic wire 103 is transferred to the tooth to induce tooth movement to support the teeth.

When the bracket 100 is attached to each tooth surface, it is usually required to be precisely bonded at intervals of about 3.5 mm to 5 mm from the tooth tip (cutting surface, occlusal surface) to create an aesthetic and functional dentition. Dental adhesives used to adhere the brackets to the tooth surface must be adhered quickly as they solidify rapidly within about 10 seconds.

Here, in order to attach the bracket to the tooth surface, a tweezer-shaped tweezer as shown in FIGS. 2a and 2b was conventionally used, and the tweezer 201 is attached to the tooth surface by approaching from the front side according to the taste of the operator. A front access type (FIG. 2A) and a side access type (FIG. 2B) tweezer for attaching to a tooth surface by approaching from the side are proposed and used. Also, as shown in FIG. 2C, a gauge 301 is used to measure the height of the bracket on the basis of the cusp 300a of the tooth 300. These gauges are divided into several gauges with different heights every 0.5mm.

In the method of attaching the bracket 100 to the tooth surface using the conventional tweezers as described above, after holding the bracket 100 with the tweezer and attaching to the tooth surface, the height of the bracket position on the tooth surface and the tooth tip ends are measured. Since the gauge is used separately or measured and bonded by the operator's naked eye, the accuracy of orthodontic correction is lowered and the work takes a lot of time.

In addition, the process of attaching directly to the teeth uses an adhesive that hardens after about 10 seconds. Therefore, the bracket is transported to the tweezers, and then, after the procedure of measuring with a gauge, the procedure is performed. There is no problem.

Patent Registration No. 98-163827 by the applicant of the present application to overcome the above problems by attaching while measuring the bracket for correcting the teeth to be located in the center of the predetermined height of the tooth surface to improve the accuracy and speed of orthodontics A supporting gauge integrated tweezer 121 has been proposed, which is shown in FIG.

However, in the case of the gauge integrated tweezers 121, because of the obstacles of the oral structures such as the lips and the cheeks, because the incisor and the small molar can be accessed, it is difficult to access the large molar side of the oral cavity and the visibility is not good. In addition, in the case of uneven teeth, there is a possibility that the correct position of the bracket is changed, so that it is difficult to attach a reliable bracket.

Therefore, the present invention has been devised to solve the above problems, it is configured to enable the rotation of the tweezers to facilitate the bracket attachment work, as well as the front teeth (front teeth) in the state of maintaining the height of the tooth surface constant Rather, it is an object of the present invention to provide an orthodontic bracket attachment device that can facilitate the access of the bracket toward the center of the tooth surface (molar) inside the mouth.

In addition, the present invention can adjust the height of the tooth cusp surface in the bracket even if the condition of the tooth is uneven, orthodontic bracket that can be uniformly attached to the bracket while maintaining the height of the bracket and tooth surface constant Another object is to provide a support device.

In addition, the present invention is another object to provide a bracket support device for orthodontics that can easily hold the bracket for the correct correction of the teeth, which can be supported to promote the accuracy and speed of orthodontics.

In addition, the present invention allows the use of two points with the occlusal as a reference reference point to correct the torque angle, rotation angle and angulation angle correction of the adjacent posterior parts even in the case of not only the uneven tooth, but also the uneven tooth. It can be carried out in a simple manner, and by matching the reference point of the bracket and the occlusal pinch held on the tweezers exactly to provide the orthodontic bracket support device that can maintain the height of the bracket and tooth surface regardless of the wear of the tooth head There is another purpose.

Another object of the present invention is to provide an orthodontic bracket support device capable of improving the accuracy and rapidity of orthodontics by using two points with the occlusal as reference reference points.

Rotation angle of the handle 6 can be adjusted within 45 ° each side.

Referring to Figures 4 to 11 the operation of the bracket attachment apparatus of an embodiment of the present invention configured as described above are as follows.

First, as shown in Figure 7, the upper and lower plates (6a, 6b) of the handle 6 as the interval expansion shaft (7) is lowered and enters between the tweezers body (3a) by tweezers ( As shown in FIGS. 8A and 8B, the gripping piece 3b of the tweezer 3 secures a space for gripping both sides of the bracket. Then, the bracket is positioned on the gripping piece 3b, and the support plate 11 positioned across the groove of the gripping piece 3b is inserted into the slot 102a of the bracket 100 to support it. When the pressing force of the handle 6 is released in this state, the gap extension shaft 7 is lifted up by the elastic force and is separated from the tweezers body 3a, and the gap between the opened grip pieces 3b is reduced and the bracket 100 is reduced. Both sides of the tie wing 102 will be gripped.

As shown in FIG. 9, while the bracket 100 is supported by the tweezer 3, the bracket 100 is approached to the tooth surface, and the bracket 100 supported by the tweezer 3 is provided. In order to attach to the correction position "A" of the tooth surface, the cusp reference plate 4 which provides a reference surface for maintaining a constant height from the cusp 300a of the tooth 300 to the bracket located at the center of the tooth surface Place on cusp 300a. At this time, the correction position "A" of the tooth surface is the height gauge 21 via the female screw 21a fastened to the height adjusting screw 22 while rotating the handle 23 provided in the height gauge 21 forward and backward. Adjust by raising. Here, the height gauge 21 is raised and lowered at a pitch interval of 0.25 mm every one rotation of the handle 23, and the calibration position of the bracket is adjusted while reading the scale 21b formed on the outer circumferential surface of the height gauge 21.

When the bracket 100 is determined at the correct position "A" of the tooth surface, the tweezers 3 approaching the tooth surface are detached and the adhesive height is applied to the rear surface of the bracket 100, and then the calibration height is adjusted as in the initial operation. Place the prepared cusp reference plate 4 on the cusp surface and join the brackets. In order to firmly attach the bracket 100, when the gripping piece 3b is advanced to the contact surface of the tooth, the bracket support 2 is pushed backward while overcoming the elastic force of the spring 15, so that the bracket 100 This is smoothly pressed onto the tooth attachment surface.

After attaching the bracket 100 to the tooth surface, as shown in FIG. 8A, the interval of the tweezers 3 is extended by the operation of entering the interval extension shaft 7 as in the initial operation of gripping the bracket. Release it.

In addition, as shown in FIG. 8B, the position of the bracket is also inclined according to the angle of the alignment according to the degree of inclination of the tooth itself to the left or the right side (hereinafter referred to as “angulation”) about the long axis of the tooth. Attached in a state. In this case, the support plate 11 of the bracket support 2 is rotated within the c-groove spacing of the gripping piece 3b to enter the slot 102a of the inclined bracket 100. In this case, as described above, after the bracket 100 is attached, the gripping piece 3b is positioned at the interface adjacent to the teeth to check the degree of parallelism, and then the attachment work is completed.

When the gripping piece 3b of the tweezer 3 is returned to its original position after the attachment operation of the bracket 100 is performed, the bracket support 2 slides forward again by the restoring force of the spring 15. At this time, the bracket support (2) is that the engaging piece 13 is caught on the outer circumferential surface of the hollow tube (1a) is that further forward movement is impossible.

When the bracket 100 is attached to the teeth inside the mouth, that is, the molar part using the tweezers 3 according to the present invention, as shown in Figs. 10 and 11, the handle 6 is disposed at a predetermined angle. Rotate as much as possible to position the housing 1 at an angle that allows easy access to the molar portion. That is, as shown in Figures 4a, 4b and 11, when the handle (6) is rotated in accordance with the position of the tooth to which the bracket 100 is attached, the angle adjusting projection (9) provided on the lower plate (6b) Is inserted into one of the five grooves 8a formed on the bottom of the extension plate 8 and fixed, and the handle 6 can be adjusted within 90 ° to attach the bracket to all teeth in the oral cavity.

On the other hand, the present invention uses the two points of the occlusal formed in the dental molar (molar) as a reference reference point in order to give the reliability of the adjustment of the orthodontic height according to the uneven surface of the tooth as the reference reference point of the molar angulation, torque In addition, it can be connected to the occlusal and support device 350 to precisely perform the rotation angle correction while maintaining the occlusal height of all posterior parts and the tooth surface of the bracket.

As shown in Figs. 12 to 14, an embodiment of the occlusal and support device includes a head reference plate 4 inserted into the channel 401a by a set screw 408 penetrating the hole 401b formed on the upper surface. A support panel 402 to be connected, a support panel 402 installed upright on both sides of the support frame 401, and having a plurality of holes 402a horizontally formed at a predetermined side surface thereof, and the support panel 402. Occlusion hole 403a is formed by one of the plurality of holes (402a) and the height adjustment screw 404 and one end thereof is in contact with the two points of the occlusal and 400a, and both sides A width gap adjusting screw 410 connected to the upper hole 402b of the support panel 402 to change the width gap between the support panel 402 to adjust the width of the bite and the position pin 403, and the support panel And a connecting shaft 409 fitted into the groove 402c formed below the 402 and into which the spring 407 is inserted.

Is a well-known fact.

Examine whether the lower end of the occlusal and the location pin 403 fits the two points of the occlusal surface such as the occlusal (400a) of the posterior portion 400.

At this time, since the distance between the two points of the occlusal and 400a is formed differently for each person or molar, the width adjustment disk 406 of the width adjustment screw 410 is forward and reverse rotation, the male screw 405 is positive, When reversely rotated, the interval of the upper part of the support panel 402 changes by the pitch shift of the upper hole 402b of the support panel 402 (the space | interval of the support panel 402 becomes narrow in FIG. 14). Accordingly, the support panel 402 is rotated about the connecting shaft 408, so that the distance between the bite and the location pin 403 is adjusted (in FIG. 14, the bite and the location pin 403 is widened). The spring 407 inserted into the connecting shaft 408 provides elasticity according to the gap adjustment of the support panel 402 to precisely adjust the width gap.

The occlusal and positioning pins 403 are positioned at two points of the occlusal wall 400a, and then the tweezers 3 holding the bracket 100 approach the correcting position of the posterior surface 400 so that the bracket 100 is closed. Fix it. At this time, if an error occurs in the height between the calibration position of the bracket 100 and the occlusal and 400a supported by the position pin 403, or when the cusp surface is worn and the upper and lower heights of adjacent teeth are changed, Alternatively, when the posterior part is inclined from side to side by an angle θ of an angulation indicating the degree of inclination from the left and right of the long axis of the tooth, the occlusal and positioning pins 403 and the supporter 402 are coupled. Loosen the height adjustment screw 404 to adjust the up and down height of the occlusal and positioning pins (403). That is, the height adjustment screw 404 can be moved up and down within the interval between the long hole (403a) formed on the upright surface of the occlusal position pin 403, it is possible to smoothly adjust the height.

In addition, the angle of the torque θ 'indicating the degree of inclination of the posterior portion 400 toward the narrowing (the gap between the cheek side and the tongue of the molars) or the labia (the gap between the lips and the tongue) around the long axis of the tooth. If it is inclined forward or backward by a degree, or when the posterior part 11 is twisted by an angle of rotation indicating how much the posterior 11 is twisted toward the buccal side, the center part of the support panel 402 is formed. The support panel 402 and the support panel 402 according to the position of the occlusal wall 400a by moving the occlusal and positioning pins 403 back and forth from the holes 402a to the two side holes 402a 'and then fixing them with the height adjusting screws 404. The horizontal width (occlusal and front and rear width) position of the attached occlusal and the position pin 403 is to be adjusted.

As described above, the occlusal and location pins 403 are positioned at two points of the occlusal wall 400a as reference reference points. Since the dimensional adjustment can be made, the bracket 100 attached to the tweezers 3 can be fixed by approaching the correct position of the posterior portion 400 precisely. Accordingly, the heights of the occlusal surfaces 400a and the brackets 100 of all the posterior parts 400 are kept constant and may be an ideal arrangement having the same inclination angle.

At this time, when the posterior part is inclined by a predetermined inclination, the support bar fixing screw 704 is released and the support body 703 is rotated by the inclination of the posterior part while watching the graduation 703b formed at the periphery of the cylindrical groove 703a. . Next, the bracket 100 is attached by bringing the tweezers 3 closer to the posterior surface in the same manner as described above.

FIG. 23 is a configuration diagram illustrating a fifth embodiment of the present invention, and more easily modified to secure a view of the head reference plate and the bracket support. FIG. That is, as shown in Figure 23, the pair of tweezers 801 is formed so that the extension portion 801a cross each other to support the tie wing of the bracket and to provide a flow area of the bracket support at the tip 801b is formed. The housing includes a tweezer support member 802 and a height gauge 805. The tweezer support member 802 is connected to one end of the pair of tweezers 801. The height gauge 805 is positioned between the pair of tweezers 801 and is connected to a height adjusting screw which is lifted at a predetermined pitch interval according to the rotation, as in the other embodiment, by a sliding bar and a hollow tube parallel thereto. Move up and down. The bracket support 804 extends through the housing, one end of which is inserted into the slot of the bracket 100 by being positioned in the groove 801b of the tweezer 801 in a 'T' shape. It is fixed to the rotary knob (803). The cusp reference plate 807 is fixed to the upper end of the height gauge 805 to set the reference plane of the correction height on the cusp of the tooth. The height gauge fixing plate 806 has one end fixed to the upper surface of the height gauge 805 and the other end fixed to the upper surface of the tweezer support member 802 to fix the height gauge 805 not to flow.

The fifth embodiment configured as described above operates similarly to the first embodiment described above. That is, the bracket 100 is approached to the tooth surface while the bracket 100 is supported by the tweezers 801, and the beach reference plate 807 is bridged so that the bracket 100 is positioned at the correction height of the tooth surface. Place on 300a. Then, the bracket 100 is in contact with the tooth surface to adjust the position. At this time, if the position of the bracket 100 does not exactly match the height of the tooth surface and is high or low, by adjusting the height adjusting screw, the cusp reference plate 807 is elevated to adjust the position of the bracket 100. In addition, by rotating the rotary knob 803 to rotate the bracket support 804 to insert one end of the bracket support in accordance with the inclination angle of the bracket slot.

When the bracket 100 is correctly aligned at the correct position of the tooth surface, the tweezers 801 approaching the tooth surface are separated to apply the adhesive to the rear surface of the bracket 100, and then the height of the correction is adjusted as in the initial operation. After placing the reference plate 807 on the cusp surface, the bracket is joined.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various permutations and modifications can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

According to the present invention as described above, by integrally configuring the tweezers and the gauge, the mounting process of the bracket can be made simple, fast, and accurate, and the height of the orthodontic bracket can be uniformly adjusted from the cusp of the tooth. It is possible to perform the correct correction of the orthodontics. In addition, since the housing equipped with the tweezer and the gauge can be rotated at a predetermined angle by the rotation of the handle, the bracket can be easily accessed to the front teeth (front teeth) or side teeth (molar teeth) side of the oral cavity. Good visibility In addition, by positioning the gripping piece on the tooth adjacent boundary surface in a state where the bracket is attached to the tooth surface, by measuring the parallelism of the gripping piece and the bracket again, the arrangement of the bracket can be ideally positioned on the tooth surface.

In addition, by using the occlusal and positioning pins supported at two points with the occlusal as reference reference points, the same applies to the adjacent posterior parts by maintaining the same height and the same inclination angle to achieve the ideal arrangement. When attaching the bracket held on the tweezer to the posterior surface, the angulation and the height can be adjusted at the same time, so that the bracket can be reliably and precisely attached.
