TECHNICAL FIELD

The present invention relates to an orthodontic clip device used for the correction process to a normal teeth correction state by applying appropriate forces to the teeth to move the teeth to the desired location, and more particularly, to an orthodontic clip device in which an orthodontic clip and a connecting wire for connecting and grasping the orthodontic clip can be naturally elastically bound through elastic restoration of a elastic member configured in the orthodontic clip, while being simply inserted to the bottom from the top of the orthodontic clip, thereby enabling the stable fixation and clean and beautiful wearing state of the teeth, while providing the easy and simple treatment.


BACKGROUND ART

In general, the orthodontic (dentition correction correction) treatment means a treatment of correcting a variety of skeletal disharmony that may occur in the course of growth, including simply aligning the crooked teeth to allow a normal teeth function, thereby making a healthy oral tissues and beautiful face figure. That is, it means functional/aesthetic treatments that move the teeth to a desired location in the alveolar bone by applying an appropriate force to the teeth.


In particular, a case where the teeth are not equally grown is called malocclusion, in the case of the malocclusion, it externally looks bad, it is not possible to functionally chew the food, and the pronunciation can be adversely affected. Furthermore, when leaving the malocclusion, the possibility of the occurrence of dental caries or periodontal disease becomes increase, and other parts of the body are also affected for a long period of time, which may induce or further worsen other diseases.


Therefore, when there is a malocclusion, it is desirable to move the teeth to the correct position and posture through the dentition correction to maintain the state of correct dentition correction. Indeed, many people acquire confidence in appearance through the orthodontic, and in some cases, often cure other diseases misunderstood as independent of the teeth through the orthodontic.


Meanwhile, an orthodontic device used as a correcting means of teeth requires a connecting wire for holding and tightening the teeth together to rightly correct the teeth when the teeth are unevenly arranged or a gap is spread, and a fixing means for fixing the connecting wire, and the orthodontic clipping device is applied at this time.


In the orthodontic clip device having such a function, in general, as a method of holding the connecting wire, a method of holding the connecting wire to the base portion of the clip base by the use of an auxiliary line, a method of fixing the connecting wire by covering or fixing it by a fixing clip after inserting the connecting wire by another fixing clip mounted on the top of the clip base, and a method of holding the connecting wire by coupling a separate lid formed on the clip base by the connecting wire are introduced.


However, since all the existing methods are methods of fixing the clip base bonded to the teeth by inserting the connecting wire from the front based on the teeth, the insertion and fixing works of the connecting wire are structurally very hard and inconvenience, and the problems of structural inconvenience and hygienic defect, such as a decline in orthodontic force to the teeth and the easy detachment of the connecting wire from the clip base itself are not still solved.


Thus, in terms of improvement in treatment convenience, reduction of and treatment period and the reduction of the treatment costs, there are demands for the development and need for orthodontic devices capable of accurately and stably transmitting the corrective force provided by the connecting wire to the teeth, while easily replacing the clip base of the bracket structural through the easy and simple work by an operator, depending on the situation or environment of the orthodontic treatment

Exemplary embodiments of the present invention will be described below in more detail with reference to the accompanying drawings. The present invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. Throughout the disclosure, like reference numerals refer to like parts throughout the various FIGS. and embodiments of the present invention.


Hereinafter, a specific configuration relation and its embodying principle of the orthodontic clip device according to the present invention will be described in detail with reference to the drawings of the preferred embodiments.


Basically, as illustrated in the use state diagrams of FIGS. 3 and 4, in the present invention, a clip base 10 as an orthodontic clip usually made of a ceramic material, and a connecting wire 70 for connecting and holding the connecting wire 70 are simply inserted from the top to the bottom (from the top vertically) of the recess of the clip base 10, and can be naturally elastically pressed and bound to the teeth 80 inserted through the elastically restoring force of the elastic clip 60 as an elastic structure of a metallic material configured in an internal recess space of the clip base 10, thereby forming an orthodontic clip device of a treatment method and a wearing structure in which a stable fixing (wearing) state can be formed to the teeth 80 to be corrected, while being structurally easily treated and simple.


First, in the clip base 10 made of a ceramic material, so as to be uniformly bonded and bound to the teeth 80, the internal part in the teeth direction as the bonding part 20 directly abutting against the teeth 80 forms a curved surface form to match the correction state of the teeth 80, the internal rear part 30 protrudes to the external side (outside) of the base portion 20, the external front part 40 is formed at an interval with the internal rear part 30 so that the connecting wire 70 can be inserted, seated and bound from top to bottom, the wire insertion hole 11 with open top is formed between the internal rear part 30 and the external front 40, the connecting wire 70 is inserted below the wire insertion hole 11, and the wire fixing hole 12 and the clip operating hole 13 are formed so that the connecting wire 70 is inserted and can be stably seated and bound, while being elastically supported by the internal elastic clip 60. At this time, it is a matter of course that the wire fixing hole 12 and a clip operating hole 13 are a single space, an internal space of the rear of the internal rear part 30 and an internal space of the front of the external front part 40, and form an integral space with the upper wire insertion hole 11.


It is configured so as to be naturally elastically operated to the connecting wire 70 basically installed on the metallic elastic clip 60 formed as the elastic means is basically installed in the clip operating hole 13 communicating with the lower side of the wire insertion hole 11 so that the connecting wire 70 inserted through the clip base 10 and the wire insertion hole 11 can be elastically support, bound and fixed to the space of the wire fixing hole 12 as the clip fixing groove 34 recessed at the front as the internal space of the clip base 10.


In particular, in the orthodontic elastic clip of the present invention, the fixing clip 50 as the same metallic fixing means as the elastic clip 60 is preferably installed, coupled and integrally configured in the clip fixing groove 34 as the wire fixing hole 12 of the internal rear 30 side communicating with the lower side of the wire insertion hole 11 so that the connecting wire 70 inserted through the wire insertion hole 11 of the clip base 10 can smoothly slide and the damage of the clip device can be structurally suppressed. Of course, the fixing clip 50 may be omitted in the configuration relation of the orthodontic clip device according to the present invention to further simplify the overall configuration relation.


Also, as the coupling state cross-sectional structure comparison diagram of FIG. 9, in the elastic clip 60 forming the elastic structure in which the intermediate part is bent at a certain angle to operate as the elastic supporting means to the teeth 80, the upper support part 62 can be basically integrally coupled to the internal part 42 of the eternal front 40 in which the wire insertion hole 11 is located, or as illustrated in the detailed structural diagram of the operating state of FIG. 7, it can be inserted and coupled to the clip binding groove 44 recessed to open downward to the external front 40.


Further, the elastic clip 60 is preferably configured so that the supporting part 63 protrudes to the lower side below the elastic part 61 while the intermediate elastic part 61 sloping so that the elastic operation can operate to the inserted connecting wire 70, and is grounded to the upper catching part 52 of the fixing clip 50 integrally coupled to the clip fixing groove 34 of the internal rear 30 in which the wire fixing hole 12 is located. This basically prevents the connecting wire 70 of a relatively small caliber from being detached from the wire fixing hole 12 to the outside through the wire insertion hole 11, by allowing the space of the wire fixing hole 12 through which the elastic clip 60 communicates with the wire insertion hole 11 to be blocked before the insertion operation of the connecting wire 70. Especially, the intermediate elastic part 61 of the elastic clip 60 improves the restoring force of the elastic operation, and is preferably formed at an angle capable of preventing scratch in the binding operation in which the connecting wire 70 is seated and elastically supported.


In addition, the clip base 10 as the orthodontic clip constituting the clip device of the present invention is configured so that, in forming the space of the wire insertion hole 11 between the internal part 42 of the external part 40 and the internal outside 30, the open upper space is formed to be smaller in size than the width of the lower space in which the elastic clip 60 is located so that the connecting wire 70 can be smoothly inserted and operated, and the upper parts 31 and 41 and the internal parts 32 and 42 facing each other of the internal rear 30 and the external front 40 forming the wire insertion hole 11 space is preferably generally in a curved surface form. The makes it possible to eliminate the feeling of foreign matter of the tongue and lips in a state of wearing on the teeth, by machining the entire protruding corner part of the clip base 10 as a curved surface and reducing its size, and by allowing the space between the adjacent orthodontic clips to spread somewhat to prevent foreign matter such as food from being structurally caught between the teeth and the orthodontic clip of the present invention, thereby providing the hygienic and aesthetic characteristics and doubling the convenience of use


Also, the base portion 20 of the clip base 10 is preferably configured so that the lower part 23 and the side part are tapered so that the tool can be easily caught when detaching the clip base 10 from the teeth 80, and the bonding part 21 of the base part 20 is preferably formed with a mesh-like embossed surface as illustrated in an enlarged view in a circle of FIG. 9 so that the bonding capability to the teeth 80 is improved.


Further, the clip base 10, as illustrated in the cross-sectional structure of FIG. 8, depending on the teeth condition and correcting method, the connecting wire 70 inserted from the top to the bottom through the wire insertion hole 11 can be configured so that the wire insertion hole 11 is formed in a slope direction (+ angle form and − angle form) on the front or rear to the teeth 80, and thus, the elastic clip 60 and the fixing clip 50 are also vertically or obliquely installed and coupled. That is, it is a matter of course that, as the level of the inclination of the wire insertion hole 11 of the upper space and the wire fixing hole 12 and the clip operating hole 13 of the lower space so as to be tilted in the front or rear direction to the teeth 80 based on the vertical direction (0 angle form) parallel to the teeth 80, the elastic clip 60 for elastically supporting the inserted teeth 80 and the fixing clip 50 on which the teeth 80 are seated and bound are also adjusted in angle in proportion thereto.


Meanwhile, as illustrated detail in the perspective views of FIGS. 1 and 2 and the enlarged view of FIG. 9, the clip base 10 made of a ceramic material constituting the orthodontic clip device of the present invention is configured so that direction and center mark 46 is preferably formed in the front part 43 of the external front 40 as instruction marks of a line and a circle representing the direction and center of the teeth 80. This can provide an effect of allowing the accurate binding position to be structurally and visually to be performed when attaching the clip base 10 as the orthodontic clip to the teeth 80.


Further, as generally illustrated in the overall configuration diagram, in the present invention, the metallic fixing clip 50 is coupled and fixed and integrally structured, the clip fixing groove 34 forming the wiring fixing hole 12 in a lower recessed space of the internal part 32 of the internal rear 30 is preferably formed in a step shape to be smaller than the cross-sectional area of the connecting wire 70 to be inserted and bound, which has a structural effect of being able to structurally more easily separate the connecting wire 70 during detachment, while being stably inserted and bound during coupling operation of the cross-section of the connecting wire 70 to the clip base 10, and furthermore, allowing more stable binding and fixing state by the supporting operation by the elastic clip 60 of the clip operating hole 13.


In particular, the upper wire insertion hole 11 and the lower wire fixing hole 12 formed in the internal space of the clip base 10 are preferably formed to be greater than the cross-sectional size of the connecting wire 70 at about 0.001 mm to 1.5 mm so that the connecting wire 70 is inserted, seated and bound from the open top (upper) direction to the bottom (lower) direction of the clip base 10, which provides structural characteristics of allowing the maintenance the stable binding state of the connecting wire 70 inserted through the wire insertion hole 11 in the wire fixing hole 12 while being smoothly guided and inserted without shaking rather than the interference fit, thereby allowing the maintenance of the binding state capable of preventing the smooth detachment of the connecting wire 70 after being structurally smoothly inserted.


Meanwhile, although the orthodontic clip device of the present invention, as illustrated in the configuration principle described above, the clip base 10 made of the ceramic material and the elastic clip 60 and the fixing clip 50 made of a metallic material are preferably basically formed by in a single structure, applied and embodied, in some cases, as illustrated in the application configuration illustrated in FIG. 10, the configurations of the basic structure may be formed and applied as a plurality of integral structures to be adjacent to each other in a symmetrical manner.


While the present invention has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
