Description

[0001] ORTHODONTIC BRACKET SYSTEM [0002]

The present invention relates to a bracket system for orthodontic treatment.

The occlusal relationship in which the teeth are not arranged or the teeth of the upper and lower jaws are not normally engaged is called malocclusion. Such malocclusion is caused not only by genetic and environmental influences but also by bad habits. Malocclusion is a problem in terms of aesthetics, so it has a bad influence on smooth social life, and it is difficult to grasp and digest foods because the chewing is not smooth in terms of function, and the pronunciation becomes inaccurate.

In order to solve such a problem, an orthodontic bracket has been devised as disclosed in the following patent documents. These orthodontic brackets apply constant force to the teeth through the wire to move the teeth. 1, a conventional orthodontic bracket includes a base 1 attached to a tooth 5 and a slot 3 into which a wire 2 is inserted, and a plurality of conventional orthodontic brackets are simultaneously inserted into a tooth 5) It is used for calibration. Accordingly, a plurality of conventional orthodontic brackets attached to the upper and lower teeth 5 of the patient are connected to each other by the wires 2, and exert a force on the teeth 5. On the other hand, since the tooth 5 of the malocclusion-related state is in a tilted state, that is, tilted in the anteroposterior direction or tilted in the lateral direction, the slot 3 of the conventional orthodontic bracket has a constant torque angle and an angulation. In the case of a conventional orthodontic bracket having a generally known torque angle and an angulation value, there is a problem in that the orthodontic efficiency is significantly lowered when applied to a nonpatient patient who performs correction without removing a tooth. Further, conventionally, the orthodontic bracket is formed of metal, which causes a deterioration of aesthetic sense.

Accordingly, there is a desperate need for a solution to the problem that arises in the conventional calibration bracket.

2, the bracket system for orthodontics according to an embodiment of the present invention is a bracket system for orthodontics that corrects teeth using an arcuate wire 200,

A base 10 on one side 11 of which is disposed on the teeth and a plurality of brackets 40 including a blade 40 protruding from the other side 13 of the base 10 and formed with a slot 30 into which the wire 200 is inserted. (100), wherein, among the plurality of brackets (100)

The maxillary incisor bracket 100 disposed at the maxillary central incisor has a torque angle of 6.5 to 7.5 degrees and an angulation of 4.5 to 5.5 degrees and the maxillary incisor bracket 100 disposed at the maxillary lateral incisor has a torque angle of 2.5 to 3.5 And an angulation of 7.5 to 8.5 degrees. An upper canine bracket 100 disposed at the upper canine is formed with a torque angle of -3.5 to -2.5 degrees and an angulation of 6.5 to 7.5 degrees, and a first premolar tooth The upper first premolar tooth bracket 100 disposed at the first premolar tooth bracket 100 has a torque angle of -7.5 to -6.5 degrees and an angulation of -0.5 to 0.5 degrees and the upper second premolar tooth bracket 100 disposed at the second premolar tooth, A torque angle of -7.5 to -6.5 degrees and an angle of -0.5 to 0.5 degrees,

The mandibular incisor bracket 100 disposed at the mandible's anterior teeth has a torque angle of -6.5 to -5.5 degrees and an angulation of -0.5 to 0.5 degrees and the mandible canine bracket 100 disposed at the mandible's canine has a torque angle The mandibular first premolar bracket 100 disposed at the first premolar of the mandible has a torque angle of -12.5 to -11.5 degrees and an angulation of -0.5 to 0.5 degrees, And the mandibular second premolar bracket 100 disposed at the second premolar of the mandible is formed with a torque angle of -17.5 to -16.5 degrees and an angulation of -0.5 to 0.5 degrees to correct the dentition of the nonpatient patient .

The orthodontic bracket system according to the present invention includes a plurality of brackets 100 as an orthodontic appliance for calibrating a patient's teeth.

Here, the orthodontic appliance is a device for correcting the occlusal relationship of the teeth by correcting the malocclusion in which the teeth are not aligned or the maxillary and mandibular teeth are not normally engaged. The bracket 100 and the wire 200 are attached to the tooth and the wire 200 is engaged with the bracket 100 to apply a constant force to the bracket 100. [ Elastic member. Here, since the bracket 100 is disposed in each of the teeth of the maxillary and mandibular teeth, a plurality of brackets 100 are used, and the plurality of brackets 100 are connected to each other by the wires 200. On the other hand, since the teeth are arranged in a curved shape from the left molar to the right molar, the wires 200 are formed in an arcuate shape corresponding to the arrangement of the teeth (see FIG. Such a wire 200 applies a force to the bracket 100 attached to the tooth, and alters the alveolar bone, so that the tooth is moved and the teeth are calibrated.

Specifically, the bracket 100 includes a base 10 and a wing 40. [

Here, the base 10 is formed in a plate shape, and one surface 11 is disposed on the teeth. At this time, the base 10 may be attached to the rear surface as well as the front surface of the teeth. Here, the front surface of the tooth refers to the surface of the tooth that looks at the lips, and the back surface of the tooth refers to the opposite surface of the tooth, which refers to the surface of the tooth that looks at the tongue.

At this time, a step may be formed on the base 10. More specifically, a step is formed at a predetermined height in the direction of the other surface 13 with respect to the one surface 11 of the base 10 so that the width of the other surface 13 of the base 10 is smaller than the width of the surface 11 . Thus, the orthodontist can easily pick up the base 10 and attach it to the teeth.

Further, a curved surface may be formed on the side surface of the base 10. That is, since the side surface of the base 10 is rounded, the width gradually decreases from one surface 11 of the base 10 toward the other surface 13. Thus, since the curved surface is formed on the side surface of the base 10, when the bracket 100 is placed on the teeth, the patient feels less sense of foreign body.

The wings 40 are protruded from the other surface 13 of the base 10 and have slots 30 to which the wires 200 are coupled. Here, the slot 30 is formed by being recessed in the direction of the base 10 from the outer surface of the blade 40. Since the wire 200 is inserted into such a slit, the bracket 100 and the wire 200 are coupled to each other. Since the wire 200 exerts a force on the bracket 100 at this time, the slot 30 may be formed to correspond to the outer circumferential surface of the wire 200, And is brought into close contact with the outer peripheral surface.

Since the bracket 100 is attached to the teeth, not only a correcting effect but also aesthetics are required. Accordingly, the bracket 100 may be formed of a single crystal sapphire ceramic. Since the single crystal sapphire ceramic has excellent transparency, it is difficult to visually recognize the bracket 100 from the outside. Therefore, the bracket 100 formed of a single crystal sapphire ceramic is compatible with any tooth, thereby satisfying the aesthetic requirement of the patient. In addition, since the single crystal sapphire ceramic is excellent in durability and resistance to coloring, it can be continuously used without replacing it in the orthodontic correction step which takes a long time.

On the other hand, the slot 30 may be coated with silica to reduce frictional force. A wire 200 is inserted and placed in the slot 30 of the bracket 100 so that a frictional force is generated between the wire 200 and the slot 30. [ Here, the force applied by the wire 200 in close contact with the slot 30 acts on the tooth to which the base 10 is attached via the base 10. At this time, when a force larger than the bonding force between the teeth and the base 10 acts on the base 10, the bracket 100 is dropped from the teeth. Therefore, when the force applied by the wire 200 is greater than the bonding force, the slot 30 is coated with silica so that the wire 200 slips in the slot 30 and the force is canceled.

The bracket 100 uses the force of the wire 200 to apply the force required for the correction to the tooth, thereby correcting the orthodontic tooth. At this time, one of the important factors that determine the correction efficiency of the teeth is torque torque and the other is Angulation (Ang). Hereinafter, the torque angle and the engagement will be described.

FIG. 3 is a cross-sectional view taken along line AA 'of FIG. 2, FIG. 4 is a plan view of a bracket according to an embodiment of the present invention, FIG. 5 is a plan view of an upper and lower jaw, This is a photograph showing the state.

3, the slot 30 is recessed in the direction of one surface 11 of the base 10, and may be formed to be inclined at an angle with respect to the one surface 11 of the base 10. That is, the slot 30 is torque, wherein the angle of makin inclined at a predetermined angle with respect to the longitudinal axis (l ₂₎ perpendicular to the extension line (l ₁₎ of the one surface 11 or the one surface 11 of the base 10 It is called angle (α). In other words, the torque angle? Is an angle between the bottom surface of the slot 30 and one surface 11 of the base 10. In this case, when one surface 11 of the base 10 has a positive value when it is tilted in a lateral direction with respect to the surface of a tooth to which it is attached, that is, when tilted toward the lingual side, that is, toward the tongue, ).

, The slot 30, as shown in Figure 4 may be formed to be inclined at an angle with respect to the horizontal axis ₍₃ l). That is, the slot 30 may be inclined with respect to direction, i.e., the horizontal axis (l ₃₎ a plurality of teeth (5) are arranged from side to side, and the horizontal axis (l ₃₎ and aenggyulreyisyeon the angular slot 30. The forming ( β).

On the other hand, the plurality of brackets 100 are disposed in the teeth of the upper and lower mandible, respectively. As shown in Fig. 5 (a), the maxilla is divided into a central tooth U1, a lateral tooth U2, a canine U3, a first premolar U4, a second premolar U4 . On the other hand, as shown in FIG. 5 (b), the mandible is disposed in the order of the anterior tooth L1, the canine tooth L2, the first premolar tooth L3, and the second premolar tooth L4 along the direction of the molar from the center .

At this time, the plurality of brackets 100 have specific torque angles and angles, respectively, in accordance with the teeth to be disposed. The most commonly used torque angle and angulation bracket system is the extraction bracket, so it is usually preceded by an extraction before calibration.

Therefore, if such an extraction bracket is used for a non-patient, the desired correction effect can not be obtained. Experimentally, as shown in the X-ray film of FIG. 6 (a), when the extraction bracket is attached to the patient who has not been subjected to an untreated patient, the left-right inclination of the teeth is large and, as shown in the photograph of FIG. 6 (b) We found that the central incisors and lateral incisors were excessively inclined. Therefore, the orthodontic bracket needs to be formed to have an optimum torque angle and an orientation that can effectively calibrate the teeth without removing the teeth.

In this regard, in order to calculate the torque angle and the angle of the bracket for calibrating the dentition of the unexplored patient, the angular strain rate was measured while varying the torque angle and the angulation, respectively. Here, the angular strain rate indicates how much the angle of the tooth has moved from its original position toward its normal position. When the tooth moves from its original position, its value gradually increases, but reaches 100% when it reaches a normal position.

Figs. 7 to 8 are graphs showing strain rates of the tooth angle according to the torque angle and the angulation. In FIG. 7 (a), the angular strain was measured by varying the torque angle of the maxillary central incisor bracket disposed in the maxillary central incisor. Specifically, the angular strain rate was measured by comparing the first and the last photographs after mounting the maxillary central incisors brackets with different torque angles to different nonpatient patient groups with similar malocclusion and after the same correction time. At this time, the angular strain was measured with a torque angle difference of 0.5 degree increments. As a result, the angular strain can not reach 50% even when the torque angle ranges from 0 to 6 degrees. This is because the maxillary central incisors are heavily inclined to the forward side in the malocclusion state and therefore require a large torque angle. Even when the torque angle increases from 8 °, the angle strain is only 50 to 60%. This is because, even when the torque angle of the maxillary central incisor bracket becomes large, the lateral incisors, the canines, and the respective brackets disposed on the first and second premolars affect each other. On the other hand, the angular strain increases sharply from the torque angle of 6 °, and the angular strain is maintained at 90% or more in the range of 6.5 ° to 7.5 °. However, it decreased after 7.5 °. As a result, it was confirmed that a significant difference in the action and effect occurred between the case where the torque angle of the maxillary central incisor bracket was 6.5 ° and the case where the torque angle was 7.5 °.

In FIG. 7 (b), the angular strain was measured by varying the angulation of the maxillary central incisor bracket disposed at the maxillary central incisor. At this time, the angle strain was measured in the same manner as described above, except that the brackets having different angulations were mounted. As a result, in the range of 0 to 4 degrees of angulation, the angle strain did not reach 50%, and the trend showed a rapid increase from 4 degrees. In the range of 4.5 to 5.5 degrees, the angle strain was maintained at 90% And decrease thereafter. Therefore, there was a significant difference between the effects of 4.5 ° and 5.5 ° in the maxillary central incisor bracket. This is due to the lack of force to move the tooth when the angle is less than 4.5 ° and to the angular strain when the angle exceeds 5.5 ° due to the influence of the bracket placed on the other tooth.

8 (a), the angular strain was measured by varying the torque angle of the mandible canine bracket disposed on the canine of the mandible. At this time, the angle strain was measured in the same manner as in FIG. 7 (a). Hereinafter, "-" indicates the direction, not the magnitude, and therefore, the reference will be made on the basis that the torque angle gradually increases, that is, when the absolute value of the torque angle gradually increases. As a result, the angular strain is less than 50% when the torque angle ranges from 0 ° to -2 °. This is attributed to the inclination of the canine. On the other hand, the angular strain rate increases sharply as the torque angle exceeds -2 °, and the angular strain reaches 90% or more in the range from -2.5 ° to -3.5 °. However, if the torque angle exceeds -3.5 °, the angle strain rate sharply drops. This is because, even if the torque angle of the mandible canine bracket is increased, it is affected by the anterior teeth and the respective brackets disposed on the first and second premolars. As a result, there is a remarkable difference in operation effect between the case where the torque angles of the mandible canine bracket are -2.5 ° and -3.5 °.

8 (b), the angular strain was measured while varying the angulation of the lower canine bracket. The angle strain was measured in the same manner as in FIG. 7 (b). As a result, the angular strain is less than 50% in the range of 0 to 6 degrees of the angulation. On the other hand, the angulation shows a tendency to increase sharply from 6 °, while the angular strain is maintained above 90% in the range of 6.5 ° to 7.5 °, and thereafter decreases. Thus, there was a significant difference in the effect between the angles of 6.5 ° and 7.5 ° in the mandible canine bracket. This results in insufficient force to move the teeth when the angulation is less than 6.5 °, and when the angulation exceeds 7.5 °, it is analyzed that the angle strain is decreased due to the influence of the bracket placed on the other tooth.

The optimum torque angle and the angle of the bracket calculated by the above-described method are as follows. At this time, the torque angle and the angulation are calculated values in consideration of the systematic action of the respective brackets.

In the case of the maxilla, the torque angle of the maxillary central incisor bracket disposed at the central incisor is 6.5 to 7.5 degrees, the angulation is 4.5 to 5.5 degrees, the torque angle of the maxillary lateral incisor bracket disposed at the lateral incisors is 2.5 to 3.5 degrees, To 8.5 degrees. In addition, the torque angle of the maxillary canine bracket disposed on the canine is -3.5 to -2.5 degrees and the angulation is 6.5 to 7.5 degrees, and the torque angle of the maxillary first premolar bracket disposed on the first premolar is -7.5 to -6.5 degrees And the angulation is -0.5 to 0.5 degrees. In addition, the torque angle of the maxillary second premolar tooth bracket disposed at the second premolar is -7.5 to -6.5 degrees and the angulation is -0.5 to 0.5 degrees.

In the case of the mandible, the mandibular incisor bracket placed in the anterior position has a torque angle of -6.5 to -5.5 °, an angulation of -0.5 to 0.5 °, and a torque angle of the mandibular canine bracket placed on the canine is -3.5 to -2.5 ° And the angulation is 6.5 to 7.5 degrees. Also, the torque angle of the mandibular first premolar bracket disposed at the first premolar is -12.5 to -11.5 degrees, the angulation is -0.5 to 0.5 degrees, and the torque angle of the mandibular second premolar bracket disposed at the second premolar - 17.5 to -16.5 DEG, and the angulation is -0.5 to 0.5 DEG.

9 is a photograph showing a tooth condition of a patient using the bracket system for orthodontics according to the embodiment of the present invention.

Each of the brackets is formed to have a torque angle and an angle in the above-mentioned range, thereby enhancing the orthodontic effect of the non-patient.

In this case, each bracket must be operated simultaneously in a systematic manner. In order to have an angular strain of 95% or more in a systematic manner, the maxillary central incisor bracket has a torque angle of 7 °, an angulation of 5 °, An angle of 3 DEG, and an angle of 8 DEG. At this time, the maxillary canine bracket has a torque angle of -3 °, an angulation of 7 °, a torque angle of -7 ° for an upper first premolar bracket, an angle of 0 °, and a torque angle of -7 ° for an upper second premolar bracket , And the angulation is formed at 0 DEG. In addition, the mandibular incisor bracket has a torque angle of -6 ° and an angle of 0 °, a mandibular canine bracket has a torque angle of -3 ° and an angulation of 7 °, a mandibular first premolar bracket has a torque angle of -12 °, At 0 °, the mandibular second premolar bracket is formed with a torque angle of -17 ° and an angle of 0 °. As a result of the orthodontic correction of the untreated patient using this bracket, as shown in the X-ray film of FIG. 9 (a), the teeth were arranged right and left, and as shown in the photograph of FIG. 9 (b) I confirmed that the maxillary and mandibular teeth were in normal engagement.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
