≪ Desc / Clms Page number 1 > ORTHODONTIC APPLIANCE AND ASSEMBLY INCLUDING THE SAME &

The present invention relates to an orthodontic appliance and a orthodontic appliance.

Generally, for a person, teeth are an important factor in producing a personal appearance due to the appearance of the image due to color and shape. Since the dentition due to the alignment of the teeth affects not only the tooth itself but also the skeletal structure of the face, It is known to be an important factor in image formation. Particularly, in the case of a person with deformed teeth, not only the influence on the external image but also the own diet is inconvenient, so correction of the dentition has been regarded as an important treatment object in dentistry. For this reason, dental orthodontics has a long history in dental treatment, and its method or technique has also been remarkably developed. In the orthodontic treatment which has been widely practiced recently, one bracket is attached to the outer tooth surface of each tooth forming the teeth, and a wire made of a strong material having a wire for orthodontic correction is bundled to the fixing structure formed on the bracket And the position or orientation of each tooth is gradually corrected over a long period of time by the external physical force of the wire.

In recent years, there has been an increase in the procedure of attaching a bracket to the inner side of the teeth, i.e., the tongue side of the teeth, connecting the wires to the teeth, and performing the desired orthodontic treatment with the external force of the wires . In addition, there is an increasing tendency to use transparent correction devices in addition to lingual correction devices. Recently, it has been known that, in a known bracket where the sizes of the occlusal surface slots and the horizontal slot are different from each other and the central portions of the arch wires to be joined are shifted from each other, the occlusal surface slots and the horizontal surface slots of the premolar, So that the arch wire of the same size can be used in combination. However, this configuration has a disadvantage in that it is troublesome for replacement and washing because of connecting the arch wire to the patient with a correcting device attached to each tooth in the oral cavity.

The tooth attaching portion 100 is divided into a plurality of And a slider 110 extending in a direction in which the surface faces. A plurality of the latching blocks 110 may be formed, and a space may be formed on the inner side of the latching block 110 through arrangements facing each other. 1, when the four latching belts 110 are extended, the seating part 112 can be formed in which the shape of the rectangular column is inserted and seated.

The assembly part 200 may include an insertion part 230 that is seated in the seating part 112 formed on the inner side by extending the latching part 110. The length of the insertion portion 230 in the insertion direction may be equal to or greater than the extension length of the sling 110. When the insertion part 230 is inserted between the latches 110, the latching part 110 and the insertion part 230 can be fixed to each other by the engagement between the protrusion 111 and the groove part 231 included in the insertion part 230. This will be described later in detail with reference to FIG.

Meanwhile, the assembly part 200 coupled to the tooth attaching part 100 through the above-described structure may have slots 210 and 220 to which a wire can be coupled at one side. Here, the wire may be a rectangular wire having a polygonal cross section, and a plurality of slots 210 and 220 corresponding to the rectangular wire may be formed. One embodiment of the present invention will be described below with reference to FIGS. 1 to 5, in which two slots 210 and 220 are formed, and each slot is referred to as a first slot 210 and a second slot 220 The slots 210 and 220 may be formed with a predetermined distance and angle apart from each other.

The rectangular wire coupled to each of the slots 210 and 220 blocks the opened slots 210 and 220 so that the rectangular wire can be fixed so as not to be separated from the assembly portion 200. The fixing part 320 and the locking part 340 may be formed on the cap 300. For example, the fixing part 320 fixing the rectangular wire coupled to the second slot 220 so as not to be detached, Can be brought into contact with and fixed to the square wire. Also, the engagement of the cap 300 with the assembly part 200 can be maintained by the latching part 340. In FIG. 1, the rectangular wire is a rectangular cross-section wire, and contacts the one surface excluding the three surfaces which are in contact with and in contact with the second slot 220, thereby preventing the rectangular wire from being separated from the assembly portion 200 .

The reason why the slots 210 and 220 are angularly spaced from each other is that the angles of the teeth of the anterior teeth and the molars in which the teeth corrector 10 is attached in the tooth correcting assembly in which a plurality of teeth correctors 10 are coupled to one wire The angular separations may be formed to compensate for the difference in angles.

Further, in order to compensate for the difference in angle of the distance, there is a case where the attachment portion 120 is attached to the anterior teeth and the posterior teeth, respectively, as described above. In the anterior teeth, the upper teeth are lower and the lower teeth are upper teeth It can be formed so as to compensate for such a distance difference.

Referring to FIG. 2 (a), the insertion portion 230 may include a groove portion 231. The groove portion 231 may correspond to the protruding portion 111 formed in the fastening base 110 of Fig. 2 (b). Such a corresponding structure may be formed such that the length of the insertion portion 230 is longer than the length of the extension portion 110 extending from the seating portion 112 so that the assembly portion 200 is engaged with the tooth attachment portion 100 . That is, the insertion portion 230 may correspond to the groove portion 231 and the projection portion 111 in a state where the insertion portion 230 is seated on the seating portion 112.

In addition, the assembly unit 200 may include not only the insertion unit 230, which is a structure for assembling with the tooth attachment unit 100, but also slots 210 and 220 to which the wire can be coupled. Here, the wire may be a square wire, and a plurality of slots 210 and 220 may be formed. In an exemplary embodiment of the present invention, two wires 210 and 220, which are first and second slots 210 and 220, The assembly 200 including the slots 210 and 220 is illustrated.

The two slots 210 and 220 may be formed at angles different from each other in the assembly unit 200, and may be spaced apart from each other by a predetermined distance. The detailed description of the different angles and predetermined distances will be described in detail below with reference to Fig. 3 in addition to the above-described description.

2B is a sectional side view of the tooth attaching portion 100 in the coupling direction with the assembly portion 200 described above. The engagement portion 110 may include a protruding portion 111. The protrusion 111 may protrude toward an inner space provided by a plurality of forked extension portions 110 and may correspond to the groove portion 231 included in the insertion portion 230. Therefore, the length of the inserting portion 230 in the inserting direction can be longer than the length of the inserting portion 112 extending from the seating portion 112. That is, when the insertion part 230 is seated in the seating part 112, the projection 111 and the groove part 231 can be in contact with each other.

In order for this coupling structure to be achieved, the latch 110 may have elasticity. When the insertion portion 230 is inserted due to the elasticity, the protrusion 111 is temporarily inserted into the groove portion 231 by a predetermined distance when the insertion portion 230 is inserted into the seating portion 112, 200 and the tooth attaching portion 100 can be maintained in a state where they are coupled to each other. That is, in the coupling process, friction may occur between the insertion portion 230 and the protrusion 111.

Further, in the case of the orthodontic appliance in which a plurality of orthodontic appliances 10 are connected to the square wire, the tooth attaching portion 100 can be pulled or pushed by the user in the state where the tooth attaching portion 100 is attached to the teeth by the user .

The above-described rectangular wire is coupled to the first slot 210 or the second slot 220, and the elasticity generated when the wire is bent is transmitted to each tooth corrector 10, so that the teeth can be calibrated.

Furthermore, since the wire is formed into a rectangular shape, not only the elasticity generated when the wire is bent but also the correction of the teeth can be performed by the torque generated when the wire is twisted. Therefore, the elasticity of the wire affects the orthodontic force and the orthodontic treatment can be performed by adjusting the degree of elasticity including the torque of the wire for the stepwise treatment.

That is, when using a circular wire and using a circular wire, it is difficult to expect correction by torque. The present embodiment exemplifies the case of using a square wire capable of calibration by torque. Therefore, when a torque-correcting force is not required, a circular wire may be employed by a person skilled in the art.

Referring to FIG. 3B, the tooth corrector 10 may be formed with an inter-slotted angle A, wherein the inter-slot angle A is an angle at which the tooth corrector 10 is attached to the molar, Which is different from each other according to the angle to be attached to the object to be calibrated. This is because one wire is connected to the first slot 210 or the second slot 220 as the case may be so that the tooth braces 10 connected to the respective slots 210 and 220 by wires can be positioned at different angles and heights . The tooth corrector 10 attached to the anterior teeth relative to the illustrated lower teeth may be positioned further upward because the angles of inclination of the anterior teeth and the height of the teeth are different from each other in the posterior teeth, It is possible to simultaneously compensate for the angle and height difference. This structure corresponds to the specific details of the different angles and predetermined distance separations described with reference to Fig. 2 (a).

Of course, the teeth corrector 10 may be positioned through the second slot 220 so that the teeth may be positioned further down than the teeth when the teeth are the reference.
