Description

Technical Field [0001] The present invention relates to a wire step pliers for orthodontic appliances,

The present invention relates to a wire step plier for orthodontic appliances.

Orthodontic treatment refers to making healthy oral tissues and beautiful facial features by correcting various skeletal incongruities that can occur during the growth process, including simply arranging crooked teeth.

As shown in Figs. 1 and 2, the Korean Patent Registration No. 1008742 (registered on January 10, 2011, entitled " Arthrow Wire " A toothbrush comprising a surface portion (10), a tongue surface portion (12), a gum surface portion (14), an occlusal surface portion (16), a mesial surface portion (18), and a centrifugal surface portion (26) for receiving a mesio-centrally extending arch wire with one side extending distally-centrally so that the wire (34) of the arch into the slot (26) is inserted and removed from the slot A main body of the apparatus; A turning member (40) mounted by the apparatus main body and forming a pivot shaft (42) extending in a mesio - centrifugal manner; A slot open position in which the opened slot side is opened and a slot closed position in which the slot side on which the shutter member 36 is opened is closed to hold the dental calibration arch wire 34 in the slot, And a shutter member (36) mounted by the pivoting member (40) so as to pivotally move with respect to the main body A swivel portion 50 mounted by the swivel member 40 for pivotal movement of the shutter member 36; And a slot closing part (52) movable together with the swivel part (50) and extending in a mesio-centrifugal manner with respect to the apparatus main body and closing the side of the slot (26) opened in the slot closing position, (36) has a swivel portion (50) surrounding the swivel member (40), the swivel portion (50) having a hole (60) extending through the swivel member (40) , The pivoting portion 50 has a wall having a cross-section at least annularly around the pivoting member 40, the wall having a radial slot 62 extending from the inside to the outside with a mesio- The wall being provided with a movable partition which can be moved about the pivot member 40 and is capable of being radially moved away from the pivot member 40 or bent toward the pivot member, As the member, the shutter member 36 There is formed a latch means member which operates mutually between the swivel portion 50 and the swivel member 40 when the shutter member is held at that position in the slot closing position, Centrifugal latch grooves 64 on one of the pivot members 40 and a mesio-centrifugal protrusion 66 on the other of the pivot portion 50 and the pivot member 40 And a latch means member formed on the side of the swivel part (50) is located in the movable partition part, which extends respectively immediately adjacent to the radial slot (62).

Such a conventional technique has a strong calibration function, but has a disadvantage in that it is not easy to perform an operation because it has a posture control spring means of an arch wire as a permanent part, and also the step of wire can not be adjusted.

As shown in FIG. 3, Korean Patent Laid-Open Publication No. 2014-2738 (Publication Date: January 1, 2014, title of invention: Design method of custom composite dental orthodontic wire and its execution) Collecting data on the tooth structure; And creating a tooth movement plan, the method comprising the steps of: preparing a set of custom composite dental orthodontic wire formed for use in combination with a bracket comprising a combination of a bracket for each bracket Determining a plurality of stages including a mounting position and an initial stage, determining a movement of the tooth from the initial tooth structure to a final tooth structure, Wherein the custom composite dental orthodontic wire used in the initial stage has at least one multidimensional bend. ≪ RTI ID = 0.0 > A < / RTI >

While this prior art teaches that a method of designing and implementing a customized orthodontic wire for use with an aesthetic orthodontic appliance is contemplated, no design guidelines or specific embodiments of the actual orthodontic wire are described There has been a fundamental problem that can not be easily carried out at the level of a person skilled in the art.

4 to 6, a handle portion is formed on one side and a grip portion is formed on the other side of the handle portion. And a second jaw which is coupled to the center of the first jaw so as to be rotatable in an intersecting manner and is formed in a symmetrical structure so as to correspond to the first jaw, and the first jaw and the second jaw (10) or a second jaw (10) so that the grip portion can firmly hold the object by a clamping force transmitted from the grip portion of the first jaw and the second jaw (12) capable of pressing the gripped wire (30) by a clamping force transmitted from the handle (11) of the first jaw and the second jaw is provided at either end of the grip (20); The other end of the first jaw 10 or the second jaw 20 is provided with a guide groove 23 having a step 22 for receiving the presser at a corresponding position of the presser 12, A cylindrical outer guide main portion 24 formed to be capable of bending and rolling the wire to be pressed by the pressing portion, thereby grasping a sharp cut portion of the wire positioned in the oral cavity during the orthodontic treatment, Wherein the wire-end bending mechanism of the dental wire is characterized in that it is capable of performing the curved processing of the cut portion of the wire only by the tightening operation.

Such prior art techniques are based on the idea that a bracket is first attached to the outer surface of a tooth, preferably the lingual surface of a tooth, as described above in the dental wire end bending mechanism, , It is possible to reduce the time-consuming time to a minimum and to eliminate the difficult process that was necessary for both physicians and patients. However, There is a problem that the degree of importance in calibration is low.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire step pliers for orthodontic appliances which can form a correct step at a time to achieve a desired orthodontic correction.

The object of the present invention is achieved by a method of manufacturing a semiconductor device comprising a first grip portion, a first shaping portion formed at the other end of the first grip portion and having an end portion divided into two and having a through hole at a side thereof, A first forming member curvedly formed in an "S " shape having a first step forming step formed thereon; A second shaping portion formed on the other end of the second handle portion and having an end portion divided into two portions and having a through hole formed on a side thereof; A second forming member curved in an "S" And a pivot pin inserted into the through hole formed in each of the first and second molding members to fix the first and second molding members, Moving between a first position in which the first and second step forming steps are spaced apart and a second position in which the first and second step forming steps are brought into close contact with each other and in which the first and second step forming steps And the distance W is 2 to 3.5 times the diameter of the wire to be bent.

Preferably, a vanadium carbide coating film is formed on the surface of the step forming steps of the present invention, and the hardness of the coating film is HV 3,500 to 4,300.

A through hole (not numbered) is formed in the side surface of the first forming portion 13.

Here, the first step molding step 15 has a coating film VC on which vanadium carbide is heat-treated, and the hardness of the coating film VC has HV 3,500 to 4,300.

The second molded member 30 is curved in an S shape and includes a second handle 31 and a second molding part formed at the other end of the second handle 31 and having an end divided into two parts 33 and a second step forming end 35 formed on the divided upper surface of the second forming part 33. [ A through hole (no number) is formed in the side surface of the second forming portion 33.

Here, the second step forming end 35 has a coating film VC on which vanadium carbide is heat-treated, and the hardness of the coating film VC has HV 3,500 to 4,300.

The first molded member 10 and the second molded member 30 are coupled in a symmetrical shape, and the pivot pin 50 is inserted and fixed to each through hole. The first molded member 10 and the second molded member 30 are held between the first position where the step forming steps 15 and 35 are spaced apart from the pivot pin 50 and the second position Lt; / RTI >
