Technical Field
The present invention relates to an orthodontic bracket used for orthodontics, and more particularly, to an orthodontic bracket having a structure that can open and close an insertion groove into which a orthodontic wire is inserted and stably restrain the orthodontic wire in the insertion groove.
Background
Orthodontics (correction of malocclusion) refers to dental treatments that use fixed or removable orthodontic devices to correct malocclusion, palatal protrusion, and malocclusions. Orthodontics have a medical role of correcting the unevenness of teeth, which may cause inconvenience in daily life, and an aesthetic role of beautifying the face by correcting misaligned teeth.
As a material used in the orthodontic appliance, metal is mainly used, but recently, ceramic has become commonly used for orthodontic treatment. For example, a bracket formed of ceramic is attached to the front region, and a bracket formed of metal is attached to a molar, that is, the rear region, but if a bracket formed of ceramic is used, the cost is increased compared to a bracket formed of metal.
As described above, the bracket is an orthodontic appliance for performing orthodontic treatment. The bracket is attached to the surface of the tooth to be corrected, and orthodontic wires such as arc wires are tied (flaps) into slots formed on the bracket. Thus, the torque of the orthodontic wire is uniformly transmitted to the tooth via the bracket to perform orthodontic treatment.
As described above, in order to perform general orthodontic treatment, brackets and orthodontic wires are used, the brackets support the orthodontic wires in a state in which the brackets are fixed to tooth surfaces (surfaces of teeth), and orthodontic forces applied by the orthodontic wires are transmitted to the teeth via the brackets on the respective teeth.
Brackets, i.e., orthodontic brackets, are generally attached to the tooth surface using a tooth bonding resin. Each bracket generally has a slot type structure in which a slot is formed in a front surface of the bracket so that the orthodontic wire is inserted into the slot, in which case a bracket base is attached to a tooth surface, and the angle of the slot is very important in order to precisely perform orthodontic treatment.
In order to tie down orthodontic wires inserted into slots in the brackets, the brackets are generally provided with side wings for tying down. Therefore, after the orthodontic wire is inserted into the insertion groove in the bracket, a wire attachment member such as a restraining elastic band is wound around the side wings to prevent the orthodontic wire from being loosened.
The conventional orthodontic bracket includes: the rubber band-type portable electronic device includes a holder main body having a plurality of side wings for coupling the rubber band and a slot formed on the holder main body, and a holder base configured to support the holder main body. Further, as a self-locking type orthodontic bracket, a clip-type binding member is used to prevent the orthodontic wire from being loosened, the clip-type binding member is coupled to a bracket body having a slot provided therein, and the binding member opens and closes the slot.

As apparent from the above description, the orthodontic bracket according to the present invention has the following effects.
First, the orthodontic bracket according to the present invention can precisely and consistently transmit the force, e.g., torque, of the orthodontic wire to the teeth, and minimize or prevent the factors causing the malfunction, e.g., deformation or damage of the binding member caused by the opening and closing of the slot.
Second, the orthodontic bracket according to the present invention includes a binding member having elasticity at an inner side of a bracket cover configured to cover a bracket main body, and allows the binding member to be seated in the bracket cover to be integrally moved with the bracket cover, thereby enabling easy opening and closing of an insertion groove for binding and releasing orthodontic wires. Therefore, the orthodontic bracket according to the present invention can realize the advantages of both the active type self-locking bracket and the passive type self-locking bracket.
Third, the surfaces of the orthodontic bracket according to the present invention, such as the contour and the front surface of the orthodontic bracket, form a curved surface of a circular arc shape, thereby being capable of minimizing the feeling caused by stimulation of the tongue, for example, caught on the orthodontic bracket attached to the teeth inside the mouth, and minimizing or preventing the problem of soft tissue damage in the mouth, for example, caused by the orthodontic bracket.
Fourth, the orthodontic bracket according to the present invention allows the binding member configured to press the orthodontic wire toward the inside of the insertion groove to be separated (removed) from the bracket cover, thereby allowing the binding member to be selectively attached to or detached from the bracket cover in accordance with the corresponding stage of orthodontic treatment.
Fifth, the orthodontic bracket according to the invention allows the bracket cover to move (open or close) only in the case where a force of a prescribed magnitude or more is applied to the bracket cover, thereby enabling the position of the bracket cover to be stably maintained in the closed state and the open state.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
Accordingly, the scope of the invention should be limited only by the attached claims and equivalents thereof.
