Description

≪ 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 following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

It should be understood that the present invention may be applied to a straight side calibrator attached to the outer surface of a tooth, although a lingual calibrator in which a tooth calibrator is attached to the inside of a tooth is described as an example.

1 is an exploded perspective view of the orthodontic appliance 10 according to an embodiment of the present invention.

Referring to FIG. 1, the orthodontic appliance 10 may include a tooth attaching portion 100, a clip fixing portion 200, an assembly portion 300, and a cap 400. The tooth attaching portion 100 includes an attachment portion 120 on which an attachment surface to be attached to the teeth T1 and T2 is formed and may include a coupling portion 110 projecting from the attachment portion 120 on the surface. The assembly part 300 is provided with a coupling groove 360 to be coupled with the coupling part 110 and a slot 310 or 320 to which a wire can be coupled is formed at one side of the body where the coupling groove 360 is formed The slots 310 and 320 may have a plurality of slots. Further, after the tooth attaching portion 100 and the assembling portion 300 described above are coupled, the clip fixing portion 200 may be assembled to fix the combined state. The clip fixing part 200 may be fixed in a form of wrapping the coupled part 110 and the coupling groove 360 from the outside.

Specifically, since the orthodontic appliance 10 is attached to a tooth through a generally used adhesive agent or the like, an attachment surface (not shown) may be provided. The attaching surface (not shown) is a relatively flat surface to be attached to the teeth, and the engaging portion 110 formed to protrude from the attaching portion 120 formed in a plate- And the engaging groove 360 may be engaged with the engaging groove 360. [ Here, the coupling may be a sliding coupling, and the movement may be restricted in the other direction except the coupling direction for the sliding coupling. For this structure, the engaging portion 110 may be formed in a trapezoidal shape that becomes wider as the engaging portion 110 moves away from the attaching portion 120, and the engaging groove 360 may be formed to correspond to the trapezoid.

1, a coupling portion 110 having a trapezoidal shape is shown. However, a coupling portion 110 having a 'T' shape may be formed for sliding coupling, which is one of coupling methods. 300 may be formed to correspond to the coupling grooves 360 formed in the first and second coupling portions 300a, 300b.

The assembly part 300 coupled to the tooth attaching part 100 through the above-described structure may have slots 310 and 320 to which the 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 310 and 320 corresponding to the rectangular wire may be formed. In an embodiment of the present invention described below with reference to FIGS. 1 to 5, two slots 310 and 320 are formed, and each slot is referred to as a first slot 310 and a second slot 320 The slots 310 and 320 may be spaced apart from each other by a predetermined distance and angle.

The rectangular wires coupled to the slots 310 and 320 may block the open slots 310 and 320 so that the rectangular wires are not separated from the assembly 300. The fixing part 420 and the locking part 340 may be formed on the cap 400. For example, the fixing part 420 for fixing the rectangular wire coupled to the second slot 320, Can be brought into contact with and fixed to the square wire. Also, the engagement of the cap 400 with the assembly part 300 can be maintained by the latching part 440. In FIG. 1, the rectangular wire is a rectangular cross-section wire, and is in contact with one surface excluding three surfaces which are in contact with and contact with the second slot 320 to prevent the angular wire from being separated.

The reason why the slots 310 and 320 are angularly spaced is that the angles of the teeth of the anterior teeth and the teeth of the teeth to which the respective tooth braces 10 are attached in the tooth braid assembly in which a plurality of tooth braces 10 are coupled to one wire The angular spacing may be formed to compensate for the difference in angle.

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.

In order to maintain the coupling relationship after the coupling through the teeth of the tooth attaching unit 100 and the assembling unit 300 described above, the clip fixing unit 200 includes the assembly 300 and the tooth attaching unit 300 100, so that each of the structures 300 and 100 can be maintained in a coupled state. Specifically, since the clip fixing part 200 is located on both sides of the clip fixing part 200 in the insertion direction of the clip fixing part 200, the clip fixing part 200 can not come out in the direction of the insertion direction after insertion. However, the clip fixing part 200 can be separated by opening both sides where the locking part 210 is formed.

That is, the engaging part 210 can contact the engaging part 110 at least after the clip fixing part 200 is inserted, and the engaged state of the assembling part 300 and the tooth attaching part 100 can be maintained.

FIG. 2 is a front view of the tooth attaching part 100 and the assembling part 300 according to the embodiment of the present invention, and FIG. 2 (a) is a front view of the tooth attaching part 100 2 (b) is a front view of the assembly unit 300 according to an embodiment of the present invention.

Referring to FIG. 2A, a coupling groove 360 formed in the assembly part 300 is formed on the coupling direction side of the tooth attaching part 100, The coupling guide 111 may be formed for the purpose of being inserted into the coupling member 110. The engaging guide 111 may be formed as an oblique surface on both sides such that the engaging guide 111 is inclined with respect to the inserting direction so as to be gradually widened during insertion.

2 (b), the assembly part 300 assembled through the tooth attaching part 100 and the attachment part 120 includes the engagement groove 360, and the inner side surface of the engagement groove 360 And may include an inner inclined portion 330. The inner inclined portion 330 may correspond to the side inclined portion 112 which is the side angle of the coupling portion 110. The side inclined portion 112 may be formed at an acute angle from the attachment portion 120, 300 may also be formed at an angle corresponding thereto.

3 (a) is a side view of the orthodontic appliance 10 according to an embodiment of the present invention, and FIG. 3 (b) is a side view of the orthodontic appliance 10 according to one embodiment of the present invention. (A) of the orthodontic appliance 10 according to an embodiment of the present invention.

The above-described rectangular wire is coupled to the first slot 310 or the second slot 320, and 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 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 310 or the second slot 320 as the case may be so that the teeth corrector 10 connected to the respective slots 310 and 320 by wires can be positioned at different angles and heights . The teeth 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 teeth and the height of the teeth are different from each other, It is possible to simultaneously compensate for the angle and height difference.

Of course, the tooth corrector 10 may be positioned through the second slot 320 so that when the upper teeth are the reference, the transposition may be positioned further downward than the molar teeth.

Figs. 4 and 5 are diagrams showing a tooth correction device 10 to which teeth are attached and a tooth correction assembly to which wires are connected to the tooth corrector 10, respectively. Fig. 4 (a) 4 is a tooth brace 10 attached to a molar tooth T2 according to an embodiment of the present invention and FIG. 5 is a perspective view of a tooth brace 10 attached to a tooth T2 according to an embodiment of the present invention Figure 1 is a perspective view of a plurality of orthodontic braces coupled with a wire 1 according to the present invention.

FIG. 4 is a view showing a coupling position with the teeth T1 and T2 described with reference to FIG. 3. The square wire is coupled to the second slot 320 of the orthodontic appliance 10 attached to the anterior tooth T1, When the first slot 310 of the orthodontic appliance 10 attached to the first tooth T2 is engaged, the teeth can be calibrated by the elasticity generated when the wire is bent. When the wire is bent in a U shape, both ends are connected to the molar T2. As a person skilled in the art selects a wire, a wire torque may be generated on the transposition T1 side based on the molar T2.

5, a wire 1 is coupled to a first slot 310 or a second slot 320 of a plurality of orthodontic appliances 10, respectively, A plurality of teeth correctors 10 arranged on the front side can be a teeth corrector 10 to be attached to the anterior tooth T1 and a teeth corrector 10 to be attached to the teeth of the teeth corrector 10 disposed on both sides thereof .

The tooth corrector 10 of this orthodontic assembly may include a tooth attachment portion 100 attached to the tooth side and an assembly portion 300 slidingly coupled with the tooth attachment portion 100 as described above with reference to Fig. have. The sliding engagement can be engaged and disengaged with the wire 1 connected in the sliding direction. Of course, the coupling and disassembly process of the clip fixing part 200 can be performed at the time of coupling and separation, and a description thereof has been described above.
