The present invention relates to an orthodontic elastic support device, by forming a plurality of hooks (Hook) at a predetermined interval in the ring portion so that one end of the elastic body can be supported on a predetermined hook portion in consideration of the orthodontic direction and the corrective force. It is.

In general, when orthodontics are to be fixed to the front or back (inner surface) of the teeth by fixing the bracket and then using a ligation band to fix the wire to the bracket, orthodontic orthodontic orthodontic orthodontic part For fixing the screw for driving, the two ends of the elastic body such as a spring to the screw and wire is to be corrected so that the anatomically correct teeth are pulled in the direction to be corrected.

That is, as shown in FIG. 1, the brackets 2 are adhered to the surfaces or the back surfaces of the general teeth (orthodontic teeth) and the orthodontic teeth 1, and then one or more using the ligation bands 3. The jade-type steel wire 4 is fixed to the bracket 2, and the orthodontic screw 5 is fixed to the alveolar bone or the inner arch of the mouth in consideration of the orthodontic direction and orthodontic force. One end of the elastic body (6) consisting of a coil spring, elastic rubber or square arc wire is hooked to the hook portion (7) fixed to the wire (4), and the other end of the elastic body (6) is connected to the screw (5). By properly hanging the tension wire 4, the tooth 1 to be corrected is moved to a normal position and corrected.

The ring portion 7 is fixed by a method such as orthogonal or inclined welding to the wire 4 portion, the hook portion is formed at the end of the ring portion 7 to support the one end end of the elastic body 6 .

In addition, since one elastic body 6 is normally caught in the hook portion 7, it is necessary to include a plurality of hook portions 7 in the wire 4 in consideration of the calibration position. It is not suitable to have a plurality of loops 7 in the part), and the welding is involved when fixing the hooks 7 to the wires 4, which not only reduces workability but also the loops depending on the degree of calibration. Although the positional movement of (7) is required, there is a problem that many difficulties arise in orthodontic treatment, such as difficult to move the position because the configuration is welded to the wire (4).

In addition, the hook portion 7 is a ring portion 7 in consideration of the fact that the locking height and the pulling angle of the elastic body 6 is changed depending on factors such as the position in which the screw (5) is placed, orthodontic orthodontic force, and the like. It is necessary to adjust the height and the fixed position on the wire, but one hook is formed in the hook portion 7, there is a problem that can not be adjusted because the pull angle is fixed.

In addition, when the teeth to be fixed (1) fixed to the maxilla, for example, the front teeth protrude forward, by fastening the screw (5) to the side alveolar pulled by the elastic body 6 can be easily corrected, but the teeth (1) fixed to the maxilla If the) is struck down, it is corrected to the normal position by pulling up the tooth 1 by using the force acting upward (pulling force) or the position acting force.

At this time, it is best to install the elastic body 6 directly above the orthodontic tooth 1 so that the orthodontic tooth 1 can be pulled upright, but the gingival tissue is positioned directly above the pulling distance of the elastic body 6, etc. In view of this, the position where the screw 5 can be placed is limited.

That is, the screw 5 can not be lifted indefinitely. In addition to the anatomical constraints, the placement position is not limited to the upside, but if the placement position is raised up as much as possible, the pulling force is insufficient, and when the screw (5) is placed low, the tooth to be corrected 1 is placed downward. There is a problem with sagging.

Then, since the molar is raised upward by the elastic body fixed to the molar portion, unwanted correction may occur, and the position of the anterior tooth varies according to the position of the screw 5.

Accordingly, the screw 5 is placed in the alveolar bone portion in the joint direction of the pulling force and pulled and corrected by the elastic body 6, so that the corrected tooth 1 is not directly above or near the corrected tooth 1. Since the screw (5) is fixed to the side of the alveolar bone relatively far away from the), the correction force (pulling force) is relatively weakened, so that the orthodontic correction takes a long time and there are problems that require several correction procedures depending on the degree of correction. There is a need for an orthodontic treatment procedure and an alternative method to reduce the pain of patients.

Accordingly, the present invention forms a plurality of hook portions at predetermined intervals in a fastening portion fixed to a wire and an annular portion extending perpendicularly (at right angles) to one side of the fastening portion at predetermined intervals in order to consider the orthodontic direction and the corrective force. It is an object of the present invention to provide an orthodontic elastic support device capable of maximizing the orthodontic effect by allowing the engaging position of the elastic body to be diversified by allowing one end of the elastic body to be supported.

In addition, an object of the present invention is to provide an orthodontic elastic support device that can be used for the left side and the right side around the front teeth by configuring the fastening portion or the loop portion 180 °.

In addition, in the present invention, the cross-sectional shape of the hook is configured to have an elliptical shape so as to be bent in a predetermined shape in a direction orthogonal to the gum using a tool (to be bent according to the shape of the gum) and in a direction parallel to the gum. It is an object of the present invention to provide an orthodontic elastic support device that can be prevented from weakening the support force by making bending difficult.

In addition, the present invention can improve the overall aesthetics by coating gold or platinum on the surface of the support device, and also by coating a metal with excellent chemical resistance and strength while being close to tooth or skin color and harmless to the human body, An object of the present invention is to provide an orthodontic elastic support device that can further improve aesthetics.

In order to achieve the above object, a fastening part fixed to the orthodontic wire, a ring part extending in a direction perpendicular to one side of the fastening part, and a plurality of hooks and curved protrusions are alternately formed in the ring part, so that the orthodontic direction and By allowing the end of the elastic body to be supported by one hook portion considering the orthodontic force, it is possible to reduce the pain of the patient such as easier orthodontic treatment and shortening of the correction time.

In addition, the present invention can be used by separating the fastening portion or the ring portion by 180 ° for the left and right for the center of the front teeth, and the cross-sectional shape of the hook to be bent according to the gum shape by configuring the oval, It is characterized by preventing the weakening of the bearing capacity by making bending difficult in the parallel direction.

In addition, the fastening portion, the base portion and the pressing portion is formed upwardly on both sides of the connection portion, forming a fastening groove having an open portion between the base portion and the pressing portion, and forming an inward locking protrusion on the upper portion of the base portion and the pressing portion to form a wire. Hook to be formed at a predetermined interval to the hook portion is one of the semi-circular or semi-elliptic open groove formed on one side, the curved protrusion is formed with a smaller open groove formed in the opposite direction of the open groove It is characterized by.

In addition, the outer diameter of each part of the ring portion is an outer diameter smaller than the hook inner diameter of the elastic body, and the cross-sectional shape of the ring portion is an elliptical having a vertical length smaller than the horizontal length so that it can be bent into a gum shape in a direction perpendicular to the gum. It is characterized in that the weakening of the bearing capacity is prevented by making bending difficult in the parallel direction.

In addition, the reinforcing protrusions are formed at one end of the curved protrusions, and the material of the supporting device is made of stainless steel, titanium, and Nitai alloys (nickel-titanium alloys) of predetermined strength, which are harmless to the human body and can support one side of the elastic body well. The surface is coated with gold or platinum to improve the overall strength and aesthetics.
