Therefore, the structure of the wire connecting member is not limited to a specific one, and various structures can be applied. Therefore, the wire connecting portion of the orthodontic appliance according to the present invention is not limited to soldering or wire connecting members.

On the other hand, the orthodontic appliance according to the present invention may further comprise an elastic member 14 for providing an orthodontic force for movement of a tooth, as in the following embodiment. The elastic member 14 may be provided on the calibration wire 10 to achieve gradual movement of the tooth, for example, movement in the direction of the root.

6 to 9, the elastic member 14 has one end supported by the calibration wire 10 and the other end supported by one of the brackets 31, So that an elastic force for moving the teeth is provided to the bracket 31. As shown in Fig.

To this end, the present invention discloses a structure in which a supporter for supporting one end of the elastic member 14 is provided on the calibration wire 10. The elastic member 14 is a structure for realizing movement of a tooth by using the elastic force of a material (an elastic material or a shape memory material), and the elastic member 14 is not limited to a rubber band or a spring.

The elastic member 14 can move the tooth by pushing or pulling the tooth using the elastic force of the material. The elastic member 14 can be moved in the same direction as the coil spring The teeth can be gradually stretched or compressed to realize the gradual movement of the tooth based on the restoring force of the elastic member.

Accordingly, the present invention can add a direct movement force to a specific tooth and minimize or prevent the reaction applied to adjacent teeth, prevent vertical movement / insertion of the tooth during its movement, maintain a vertical position, It is not necessary to disperse various types of orthodontic appliances in the oral cavity, thereby minimizing the burden on the patient and the practitioner.

A coil spring may be applied as an example of the elastic member 14 and the calibration wire 10 may penetrate the inside of the coil spring 14 in the longitudinal direction so that the position of the coil spring 14 Lt; / RTI > Accordingly, the calibration wire 10 serves as a support for supporting the elastic member 14 and can guide the pulling direction of the bracket 31.

When the orthodontic wire 10 is bent (bent) into a predetermined shape according to the intention of the operator, the coil spring 14 is also deformed corresponding to the shape of the orthodontic wire 10, It is installed inside the oral cavity.

In this embodiment, an example of moving the second molar 1a by moving the second molar 1a rearwardly, i.e., in the centrifugal direction, is realized, and the wire connecting portion 13 performs the function of the supporter The orthodontic appliance according to the present invention may be applied to movement of teeth other than the second molar 1a and the orthodontic wire 10 may be provided with the supporter separately from the wire connection part 13. [

In this embodiment, since the wire connecting portion 13 functions as the supporter as described above, when the wire connecting portion 13 is formed by the above-described soldering as in the first embodiment of the calibration wire, The wire connecting portion 13 is formed to be thicker than the thickness of the second wire 12, particularly, the diameter of the coil spring, and is applied as the supporter.

Of course, when the wire connecting portions are formed by the wire connecting members 13a and 13b, the thickness of the wire connecting members 13a and 13b may be thicker than the diameter of the coil spring.

One end of the elastic member 14 may be supported by the fixed anchor 50, but one end of the elastic member 14 may contact the gum as the elastic member 14 approaches the fixed anchor 50 The one end of the elastic member 14 is supported by the supporter and in particular the wire connection portion 13 so that the elastic member 14 and the fixed anchor 50 are spaced apart from each other by a predetermined distance It is good to leave.

The elastic member 14 is elastically compressed between the wire connection portion 13 and the first bracket 31 of the second molar 1a so that the elastic member 14 is elastically compressed. The restoring force of the second bracket 31 can provide a direct pushing force to the second molar 1a via the first bracket 31 so that it does not give any reaction to other nearby teeth, The burden on the alveolar bone and the root tissue can be reduced.

Of course, when the elastic member 14 is elastically stretched between the wire connecting portion 13 and the first bracket 31, it may provide a direct pulling force to the second molar 1a.

As described above, in the orthodontic appliance 10 of the present embodiment, the first wire 11 is supported by the fixed anchor 50 and the second wire 12 is supported by the second molar 1a Since the orthodontic force of the elastic member 14 is directly applied to the first bracket 31 in a state of guiding the first bracket 31 and the second bracket 31, accurate and effective dental movement can be easily realized without any reaction between the teeth and the procedure time can be shortened.

The connecting wire of the first wire 11 constitutes a closed loop so that the calibration wire is not separated from the fixed anchor 50 even if a force is applied to the calibration wire 10 in any direction.

An orthodontic system for performing orthodontic correction on the posterior portion using the orthodontic appliance according to this embodiment will be described with reference to FIGS. 7 to 9. FIG.

The orthodontic wire 10 of the orthodontic appliance according to the present invention deformed into a shape suitable for the purpose of the orthodontic treatment and the setting environment of the orthodontic wire is inserted into the elastic member 14, that is, the inside of the coil spring. Since the calibration wire 10 is divided into the first wire 11 made of a soft material and the second wire 12 made of a hard material as described above, the first wire 11 is free It can be easily varied.

In the present embodiment, the first wire 11 is held by a fixed anchor 50 fixed to the jaw, in particular a screw, and fixed to the supporting structure of the fixed anchor 50, And in a case where it is determined that the installation direction of the calibration wire or the other anchoring structure to the fixed anchor is not appropriate in the process of mounting the calibration wire 10 on the oral cavity of the patient, The shape of the wire 11 can be easily changed.

The second wire 12 is inserted into the coil spring 14 in a state deformed to have a shape corresponding to the relative position of the first bracket 31 and the fixed anchor 50, The orthodontic wire 10 on which the probe 14 is mounted is installed inside the oral cavity of the patient, for example, on the narrow side of the maxilla as shown in Figs.

7 to 9, brackets 31, 32, 33 and 34 are fixed to the teeth 1a, 1b, 1c and 1d for correcting the teeth, , 32, 33 and 34 are adhesively fixed to each tooth by using a dental adhesive resin. And the line wires 35 connecting the brackets are mounted along the brackets. The brackets fixed to the second molar 1a, the first molar 1b, the second premolar 1c and the first premolar tooth 1d are successively inserted into the first bracket 31, The second bracket 32, the third bracket 33, and the fourth bracket 34, respectively. For reference, the tooth marked 1e is a canine.

In this embodiment, the orthodontic system is configured such that the orthodontic appliance pushes the second molar 1a directly in the centrifugal direction. At this time, one end of the coil spring 14 is connected to the wire of the calibration wire 10 And the other end of the coil spring 14 is supported by the first bracket 31 so that the coil spring 14 is compressed. The second wire 12 is inserted into the wire hole 31a formed in the first bracket 31 in the transverse direction and then the connection link of the first wire 11 is inserted into the fixing anchor 50 ) To be installed.

When the orthodontic system using the orthodontic appliance according to the present embodiment is installed in the oral cavity of the patient through the above process, the coil spring 14 provided on the orthodontic wire 10 is inserted into the first bracket 31 The bracket 31 of the second molar 1a is pushed rearward so that movement of the second molar 1a is realized and the orthodontic wire 10 is inserted into the teeth 1, The vertical position of the second molar is maintained at the time of calibration so that the effective movement of the teeth can be facilitated.

In order to prevent the second molar 1a from being opened between the second molar 1a and the first molar 1b by the movement of the second molar 1a and the bracket 32 provided in the first molar 1b, An elastic spring may be further provided as an auxiliary elastic member 43 for pushing the first molar 1b toward the second molar 1a side between the brackets 33 provided in the two premolar teeth 1c, Accordingly, the movement of the second molar 1a and the first molar 1b in the direction of the arrow shown in Fig. 9 can be realized at the same time. The auxiliary elastic member 43 is installed on and supported by the line wire 35.

Although the present invention has been described by taking the orthodontic treatment as an example by pushing the maxillary second molar 1a, the present invention is not limited thereto. In addition to pushing or pulling other teeth other than the second molar 1a, So that unnecessary use of other correcting mechanisms can be minimized and the reaction against other teeth can be minimized when the second molar 1a is moved.

When the second molar 1a is pushed backward, the coil spring 14 is stretched so that the resilient compressive force of the coil spring 14 gradually decreases, and the corrective force applied to the second molar 1a gradually decreases According to the orthodontic wire 10 of the orthodontic appliance according to the present invention, a practitioner can easily reapply the compressive force of the coil spring 14 Therefore, the ease of operation is improved.

In other words, when the operator hooks up the connection ring of the first wire 11 having a soft material by using the dental forceps, the connection width of the connection ring is narrowed to the left and right, The coil spring 14 is compressed again while being moved rearward.

That is, since the first wire 11 of the calibration wire 10 according to the present invention is made of a soft material and can be easily changed in shape using a small force, the practitioner can separate the connection ring from the fixed anchor 50 The compression force of the coil spring 14 can be easily reapplied and the calibration mechanisms constituting the orthodontic system can be replaced or the coil spring can be reinstalled for the reattachment of the compression force of the coil spring.

Although not shown, the first wire 11 may be installed through the anchor wire hole 51 formed in the fixed anchor 50 in a straight or bent state, which is not bent.

10 shows another example of orthodontic correction by the orthodontic appliance according to the present invention. In this embodiment, the orthodontic wire is installed in the oral cavity almost in a straight line, and the first molar or the second premolar 1c As an example of orthodontic correction by the addition of an orthodontic force, this is an example in which some teeth, for example, one of the posterior teeth, is extracted or missing.
