Description

Orthodontic brackets and how to use them

[0001] The present invention relates to an orthodontic bracket and a method of using the same, and is characterized in that a cap having an appropriate slot can be selected according to the thickness and shape of an orthodontic wire selected during the orthodontic process, thereby providing appropriate orthodontic force to teeth throughout the entire orthodontic process. In addition, the invention is characterized in that convenience is increased and orthodontic treatment can be performed safely by fastening a base member and a cap member necessary for orthodontic wire correction using a slide and / or snap fit method.

[0002]

[0003] Uneven dental alignment or malocclusion can be caused by factors such as abnormal development of the teeth themselves or jawbones. People with uneven or misaligned teeth may cover their mouths when talking or smiling. This can also lead to a more passive attitude in interpersonal relationships, making it difficult to lead a fulfilling social life. Furthermore, when eating, they may not be able to grind food evenly, and food can become lodged between the teeth, potentially leading to various dental or digestive problems.

[0004] To address these issues, orthodontic techniques are being researched and developed to apply continuous force to the teeth, causing tooth movement along with remodeling of the alveolar bone surrounding the teeth.

[0005] A representative example is the braces-based orthodontic method used in orthodontic treatment to correct misaligned teeth (dentition). This orthodontic treatment uses brackets that are attached to the teeth, wires made of shape-memory materials or stainless steel that are connected to the brackets to actually hold the teeth in place, and accessories such as ties that secure the orthodontic wires. In other words, to correct teeth, brackets are fixed to the surface of the teeth with resin, and then wires are inserted into the brackets fixed to each tooth. The wires are bent or bent to fit the position of each tooth, taking into account the shape of the teeth or dentition, and are connected to the teeth through the brackets for a long period of time so that the wires transmit a force to the teeth to return to their original position (even dentition shape), thereby correcting the position of the teeth. And, throughout the entire process of orthodontic treatment using brackets, the size and direction of the force to be transmitted to the teeth are different, so an orthodontic wire of an appropriate size and thickness must be selected and replaced. For this purpose, a self-ligating bracket has been developed.

[0006] However, since these conventional brackets are used continuously while attached to the teeth, the slots where the orthodontic wires are seated are designed to have a size corresponding to the thickness of the largest orthodontic wire. This makes it impossible to provide the appropriate orthodontic force required at each stage of orthodontic treatment. In other words, when the orthodontic wire is selected at each stage of orthodontic treatment, the slot size must be changed accordingly. However, it was difficult to change the slot size corresponding to this with brackets that were continuously attached to the teeth. As a result, brackets with slots corresponding to the thickness of the largest orthodontic wire were generally used. However, in this case, the space between the orthodontic wire and the slot was too large, limiting the proper transmission of the weak, continuous force delivered by the wire to the teeth. Furthermore, from the practitioner's perspective, conventional brackets presented the problem of requiring a cumbersome process of installing or replacing the orthodontic wire, which required a lot of time and effort.

[0007]

[0008] The present invention has been devised to solve the above problems, and provides an orthodontic bracket and a method of using the same, which can effectively transmit the restorative force of an orthodontic wire to teeth and periodontium by supporting the selection and use of an appropriate orthodontic wire throughout the entire orthodontic process through the selection of various cap members.

[0283] Additionally, a method of using an orthodontic bracket is provided, characterized in that the identification mark is formed in relief.

[0284] In addition, a method of using an orthodontic bracket is provided, characterized in that the base member and the cap member are formed of resin, and the resin is an engineering plastic.

[0285] The orthodontic bracket and method of using the same according to the present invention have the following effects.

[0286] First, it has the effect of allowing for the appropriate force to be applied to teeth, adjusted and applied at different times, throughout the entire orthodontic treatment process. In other words, it supports the easy use of appropriate orthodontic wires throughout the entire orthodontic treatment process. Specifically, by selecting and using an appropriate cap based on the shape and thickness of the orthodontic wire being used, it effectively transmits the orthodontic wire's restorative force to the teeth and periodontal tissue. This can shorten the orthodontic treatment period and minimize side effects such as root resorption.

[0287] Second, since conventional brackets do not provide slots appropriate for the size and shape of the orthodontic wires used in each stage of orthodontic treatment, brackets with slots for the largest orthodontic wires had to be used, or the cumbersome task of removing the bracket attached to the teeth and attaching another bracket had to be performed. However, the present invention provides brackets with slots appropriate for the size and shape of the orthodontic wires used by replacing the cap, thereby increasing convenience for both the user and the practitioner.

[0288] Third, in the case of an embodiment in which the base member and the cap member constituting the bracket are joined and fastened in two ways, that is, using a slide and a snap fit, among the embodiments of the invention, the convenience of use is increased, and the stability during the entire process of orthodontic treatment is also improved.

[0289] Fourth, in stages where the use of transparent orthodontic devices such as Invisalign is required during the orthodontic treatment, the use of transparent orthodontic devices can be supported, thereby providing the advantages of both bracket-based orthodontic devices and transparent orthodontic devices. Specifically, by applying temporary resin to the base member, it can function as an attachment, thereby achieving the effect of achieving more effective orthodontic treatment by selectively combining the advantages of bracket-based orthodontic devices and transparent orthodontic devices such as Invisalign. For reference, in addition to the method of applying temporary resin to the base member, a method of attaching a cap member to the base member may also be used.

[0290] Fifth, orthodontic brackets are secured without using wires, and the elastic bands are smaller and smoother than conventional brackets, reducing the risk of food getting caught or causing damage to the oral cavity. Furthermore, foreign body sensations are also reduced.

[0291] Sixth, in the case of existing brackets that only provide a single fixed-size slot, there were many cases where stainless steel wires had to be used primarily. However, according to the present invention, the force provided by nickel-titanium wires, which have low rigidity but can exert a weak and continuous force, can be effectively transmitted to teeth, thereby achieving the effect of enabling nickel-titanium wires to be used more actively in orthodontic treatment. In addition, through this, the number of replacements of orthodontic wires in orthodontic treatment is also drastically reduced, thereby increasing convenience for patients and / or orthodontists.

[0292] Seventh, the shape of the second wire slot of the cap member and the direction of slide progression can be predicted through the identification mark formed on the cap member, thereby increasing the convenience of users such as those performing corrections, and also having the effect of preventing mistakes in advance.

[0293] Eighth, the present invention has the effect of allowing the bonding agent to not overflow into the portion where the first wire slot or the slide-type and / or snap-fit-type bonding is made through the pattern formed on the first-first surface of the base member, while allowing the excess resin or other bonding agent to move up and down the base member so that it can be used for attachment to the tooth surface, thereby enabling more convenient treatment and more solid attachment of the base member.

[0294] Ninth, in the case of an embodiment in which the cap member and the base member are connected in a hinge manner, the connection between the cap member and the base member can be more easily supported, and at the same time, the sliding movement of the premolars and / or molars can be easily supported during the process of orthodontic treatment.

[0375] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. The present invention is susceptible to various modifications and various forms. Specific embodiments are illustrated in the drawings and described in detail in the text.

[0376] However, this is not intended to limit the present invention to a specific disclosure form, but should be understood to include all modifications, equivalents, or substitutes included in the spirit and technical scope of the present invention.

[0377] In addition, in the description of the present invention, terms such as "first", "second", etc. are used only for the purpose of distinguishing one component from other components, and are not used to limit any meaning. In addition, singular expressions include plural expressions unless the context clearly indicates otherwise, and terms such as "comprise" or "have" should be understood to specify that a feature, number, step, operation, component, part, or combination thereof described in the specification exists, but do not exclude in advance the possibility of the existence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0378] Drawings 1 to 13 are drawings illustrating conventional orthodontic devices, and are drawings illustrating conventional orthodontic devices and problems and limitations that may arise from the use of such conventional orthodontic devices.

[0379] Drawing 1 is a drawing showing the appearance of a transparent orthodontic device, also called invisalign, which is one of the conventional orthodontic devices.

[0380] Invisalign, also known as clear aligners, are made of clear plastic and are less noticeable than traditional metal braces, making them a popular choice for many people. Invisalign is custom-made for each patient's individual teeth structure and uses a series of aligners to gradually move teeth into the correct alignment. Typically, aligners are replaced every two weeks, gradually moving teeth and correcting the bite.

[0381] However, since correction using these Invisalign devices requires continuous replacement with new ones, the cost of correction is higher than that of correction using conventional metal correction devices. At the same time, in cases of complex or severely misaligned teeth, the treatment effect is low, so the correction period is prolonged or the desired teeth correction effect is not achieved.

[0382] Drawing 2 is a drawing showing an example of a conventional metal orthodontic device, and Drawing 3 is a drawing showing how such a conventional metal orthodontic device is used.

[0383] Drawing 2 schematically shows the appearance of a conventional metal orthodontic device (20) that is attached to and used on teeth. This conventional metal orthodontic device (20) is attached to an individual tooth (T) and is used to support a orthodontic wire (10). More specifically, this conventional metal orthodontic device (20) is attached to the tooth (T), and a wire (50) is used to secure the orthodontic wire (10) and the conventional metal orthodontic device (20). Through this, the restoring force of the orthodontic wire (10) made of a shape memory alloy or the like is transmitted to the tooth (T), so that the tooth (T) is aligned to the correct position. In this process, if necessary, a rubber band may be used to transmit additional force to the rubber band hook (21) to adjust the alignment of the jaw and the teeth.

[0384] These conventional metal orthodontic devices (20) have the advantages of being more effective in treating serious tooth misalignment, requiring less treatment time, and being less expensive than transparent orthodontic devices such as Invisalign. However, in order to effectively perform tooth alignment and occlusion using these conventional metal orthodontic devices (20), continuous observation and adjustment by a specialist are required. However, since the conventional metal orthodontic devices (20) are not only difficult to remove once attached to the teeth, there was a disadvantage in that there was a limit to supporting the use of an appropriate orthodontic wire (10) for each treatment period. In addition, there was inconvenience from the practitioner's perspective in that the orthodontic wire (10) had to be individually fixed to the conventional metal orthodontic devices (20) using a wire (50), etc., and furthermore, there was a problem in that food could get stuck in the mouth or the tongue could be injured due to the protruding rubber band hanger (21) or wire (50).

[0385] Drawings 4 to 6 are drawings showing the appearance of a conventional self-ligating bracket and a method of using the same. First, Drawing 4 shows the appearance of a conventional self-ligating bracket with the cover closed, Drawing 5 shows the appearance of a conventional self-ligating bracket with the cover open, and Drawing 6 shows the appearance of an orthodontic wire being fixed using a conventional self-ligating bracket.

[0386] In order to solve the inconvenience of fixing or replacing the orthodontic wire (10) during the process of correcting teeth (dentition) using the conventional metal orthodontic device (20) discussed above, a conventional self-ligating bracket (30) was developed, which can install or replace the orthodontic wire (10) by opening and closing the cover (31), as shown in the drawing. This conventional self-ligating bracket (30) has the advantage of increasing convenience for the practitioner, etc., in that there is no need to fix the orthodontic wire (10) one by one using a wire (30), etc. In addition, the frictional force between the orthodontic wire (10) and the conventional self-ligating bracket (30) is also reduced compared to the conventional metal orthodontic device (20), so there is also the advantage of shortening the treatment time. However, since these conventional self-ligating brackets (30) are generally used in a fixed state by being attached to the teeth (T), there has been a problem that they do not optimally support the orthodontic wires (10) used in each stage of orthodontic treatment, as explained below through the following drawings. In addition, there has also been a problem that the cover (31) frequently breaks down.

[0387] Drawing 7 is a drawing showing a comparison of the orthodontic wire used in comparison with the conventional self-ligating bracket, etc.

[0388] In orthodontic treatment, an appropriate orthodontic wire (10) must be selected and used for each treatment step. In order to gradually move the teeth (T) to the desired position, it is preferable to initially use a light and flexible thin orthodontic wire (10) to apply continuous and weak force, and then replace the orthodontic wire (10) with a thicker and harder one as the treatment progresses. However, in treatment using a conventional metal orthodontic device (20) or a conventional self-ligating bracket (30), since it is difficult to remove or replace the device fixed to the teeth (T), rather than using a conventional self-ligating bracket (30) having an appropriate slot (SL) to match the orthodontic wire (10), a bracket having the largest slot (SL) in preparation for the largest diameter orthodontic wire (10) to be used in the future is generally used. For example, although the conventional self-ligating bracket (30) provides two slot (SL) specifications, this only supports the selection of the slot (SL) specification within the approximate range of wires used at the start of treatment, and is not prepared to support the selection of an appropriate wire according to the time during the treatment process, and in order to use an orthodontic wire (10) that is outside the range of the conventional self-ligating bracket (30) attached, the old one had to be removed from the tooth and a new one had to be reattached to the tooth.

[0389] In this way, if the size of the slot (SL) does not match the orthodontic wire (10), when using the orthodontic wire (10) with a small diameter that is initially used, the force is not properly transmitted to the teeth, and if a orthodontic wire (10) with a large diameter is suddenly used to solve this problem, the optimal orthodontic force is not applied, resulting in the problem of the tooth root being absorbed.

[0390] Drawings 8 to 13 are drawings showing limitations that occur when a slot (SL) of an appropriate size is not supported compared to the diameter of the orthodontic wire.

[0391] First, Drawing 8 shows the use of a thin-diameter orthodontic wire (10) to provide a weak and continuous force in the early stages of orthodontic treatment. However, since the slot (SL) of a conventional metal orthodontic device (20) or a conventional self-ligating bracket (30) is designed to match the diameter of the thickest orthodontic wire (10), the gap between the orthodontic wire (10) and the slot (SL) is large, as shown in Drawing 9. Therefore, the weak and continuous force provided by the orthodontic wire (10) is not properly transmitted to the teeth, making it impossible to achieve the intended purpose in the early stages of orthodontic treatment.

[0392] After going through the initial orthodontic treatment process like this, the orthodontic wire (10) is replaced with a thicker and larger diameter stainless steel wire, as shown in Drawing 10. When the orthodontic wire (10) comes into contact with the slot (SL), it is recognized that there is a difference in height between the teeth (T), and only then does the movement of the teeth (T) begin. However, as can be seen from Drawing 11, since the orthodontic wire (10) changed in this way does not come into contact with the slot (SL) at an optimal distance, it fails to provide the optimal orthodontic force targeted at the teeth (T), but instead provides a strong and intermittent force to the teeth (T). In this case, the movement speed of the teeth (T) is slow, and the side effect of the tooth root being absorbed also occurs.

[0393] Drawings 12 and 13 are drawings showing the appearance of the tooth root being absorbed during orthodontic treatment.

[0394] Root resorption, which is a phenomenon in which the length or volume of the root of a tooth (T) decreases, is known to occur frequently when a strong and intermittent force is continuously applied to the tooth (T). As previously discussed, if an appropriate slot (SL) is not prepared in relation to the diameter and size of the orthodontic wire (10), and a weak and continuous force is not provided to the tooth (T) in the initial orthodontic stage, and then a strong and intermittent force is suddenly provided to the tooth (T) through wire replacement, the possibility of this occurring may increase, and such root resorption may cause discomfort such as pain to the patient.

[0395] Therefore, it is necessary to provide and develop a new orthodontic bracket that can shorten the period of orthodontic treatment while minimizing side effects such as root absorption by appropriately maintaining the gap between the orthodontic wire (10) and the bracket used at each stage of orthodontic treatment so that optimal orthodontic force is provided to the teeth (T).

[0396] Figure 14 is a graph showing the force applied according to displacement depending on the material of the orthodontic wire used.

[0397] As can be seen from the graph, when there is a displacement change of 3 millimeters (mm), the nickel-titanium (Ni-Ti) wire exerts a force of about 6 Newtons (N), and this force is almost maintained until a displacement of 1 millimeter, whereas the stainless steel wire exerts a large force of 22 Newtons at a displacement change of 3 millimeters, and the force decreases rapidly as the displacement decreases. Through this, it can be seen that the nickel-titanium wire is most ideal for providing a weak and continuous force, which is the ideal corrective force suitable for orthodontic treatment.

[0398] However, as previously examined, since the conventional self-ligating bracket (30) or the conventional metal orthodontic device (20) has a slot (SL) for using the largest diameter wire, it cannot properly transmit the force provided by a wire with low rigidity but high spring back, such as nickel-titanium, to the teeth (T), and therefore many orthodontists have used thicker stainless steel wires to perform orthodontic treatment. However, when such thick stainless steel wires are used, intermittent and strong force is exerted, which slows down the movement of the teeth (T), and there is a high possibility that side effects such as root resorption may occur.

[0399] Therefore, there is a need to provide and develop a new orthodontic bracket that supports the active use of nickel-titanium wires as orthodontic wires (10), thereby enabling orthodontic treatment to be completed in a shorter period of time and preventing side effects such as pain and root resorption. For reference, nickel-titanium wires have the characteristics of low stiffness, high spring back, and high stored energy. Low stiffness means that they are flexible and easy to manipulate, high spring back means that they have an excellent ability to return to their original shape after being deformed or bent, and high stored energy means that they store a significant amount of energy through deformation and release it while returning to their original shape. In summary, nickel-titanium wires store a significant amount of energy even with small deformation, and release this stored energy as they gradually return to their original shape, thereby providing a weak but continuous orthodontic force to the teeth.

[0400] Drawing 15 is a drawing showing the appearance when orthodontic wires of various sizes and shapes are placed in slots provided by conventional self-ligating brackets or conventional metal orthodontic devices, and Drawing 16 is a drawing showing the shape and size of slots that should ideally be provided according to the size and shape of orthodontic wires.

[0401] As previously discussed, the conventional self-ligating bracket (30) or the conventional metal orthodontic device (20) can only provide one fixed-size slot (SL), and if the size of the slot (SL) is to be changed, the bracket must be removed from the tooth (T) and another bracket must be attached. For this reason, only one bracket is often used throughout the entire course of orthodontic treatment for the tooth (T). In this case, if the gap between the slot (SL) and the orthodontic wire (10) is too large, the restorative force provided by the orthodontic wire (10) is not properly transmitted to the tooth. Conversely, even if the gap is too small and the friction between the orthodontic wire (10) and the slot (SL) is increased, the force exerted by the orthodontic wire (10) is offset by the frictional force, so that an appropriate orthodontic force is not provided to the tooth (T).

[0402] Therefore, in order to provide an appropriate corrective force, it is appropriate to have a gap of about 0.1 millimeter (mm) between the orthodontic wire (10) used and the slot (SL) as shown in Drawing 16. Since the present invention can provide slots (SL) corresponding to various sizes and shapes of the orthodontic wire (10) used, it is possible to achieve the effect of transmitting the appropriate corrective force required for each stage of orthodontic treatment to the teeth (T) as it is. Furthermore, when mainly using nickel-titanium wires that continuously provide weak force, one nickel-titanium wire provides corrective force over a wider range in orthodontic treatment, so the number of replacements of the orthodontic wire (10) can also be reduced. Specifically, since the number of replacements, which was about 9 times in general orthodontic treatment, only 3 times is required, the convenience of patients and / or orthodontists in orthodontic treatment can be expected to increase.

[0403] Based on the above-described contents, the orthodontic bracket according to the present invention and the method of using the same, as well as its configuration and operation method, will be examined in detail one by one.

[0404] Drawing 17 is a drawing showing the overall appearance of the orthodontic bracket according to the present invention.

[0405] The orthodontic bracket (1000) according to the present invention comprises a base member (100) and a cap member (200), and transmits the orthodontic force provided by the orthodontic wire (10) to the tooth (T) through a wire slot (WS) formed by combining and fastening the cap member (200) onto the base member (100) that is directly attached to the surface of the tooth (T). The cap member (200) combined with the base member (100) can be replaced or changed with another cap member during the orthodontic treatment for the tooth (T), and by changing the cap member, a wire slot (WS) suitable for the shape and diameter of various orthodontic wires (10) can be provided, thereby providing the tooth with the appropriate orthodontic force required at each stage of the orthodontic treatment for the tooth (T). Here, the base member (100) and the cap member (200) can be formed using a resin, and specifically, a white or transparent engineering plastic can be used so as not to be easily recognized from the outside. For reference, the base member (100) and the cap member (200) are fastened through a slide and / or snap fit method, and this part will be examined in more detail with reference to the drawings below.

[0406] Drawing 18 is a drawing showing a side view of a base member constituting an orthodontic bracket according to the present invention.

[0407] The base member (100) that is attached and fixed to a tooth (T) using resin (RE) and serves as the basis of the orthodontic bracket (1000) according to the present invention may have a first-first surface (100-1) that is used for attachment to the tooth (T) and a first-second surface (100-2) that is in contact with the cap member (200), and a first wire slot (110) that forms a wire slot (WS) through combination with the cap member (200) may be formed on the first-second surface (100-2). The orthodontic bracket (1000) according to the present invention is used by sliding the cap member (200) laterally on the base member (100), and the specific process thereof will be described below with reference to the drawings. For reference, the end of the side of the base member (100) through which the cap member (200) enters may be slightly tapered so that the cap member (200) can easily slide in, and the first wire slot may be formed with a curved surface in the width direction (Y).

[0408] Drawing 19 is a drawing schematically showing a method of using an orthodontic bracket according to the present invention.

[0409] With the base member (100) fixed at a desired position on the surface of the tooth (T), the orthodontist, etc., places an orthodontic wire (10) suitable for the corresponding orthodontic step in the first wire slot (110) of the base member (100), and then slides the cap member (200) thereon toward the base member (100) to fasten and couple the cap member (200) to the base member (100). More specifically, the cap member (200) is fastened to the base member (100) through the process from (a) to (c) of the drawing, and the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) slide along the 1-1 base fastening member (180) and the 1-2 base fastening member (190) of the base member (100), and finally, a snap-fit ​​connection is made, and the mounting of the cap member (200) is completed. That is, the base member (100) and the cap member (200) are slide-fastened, and then a snap-fit ​​fastening is additionally performed. The detailed configuration of the base member (100) and the cap member (200) for this purpose will be explained below.

[0410] The present invention has the effect of supporting easy use of an appropriate orthodontic wire (10) throughout the entire orthodontic treatment process, since an appropriate cap member (200) can be selected and used according to the shape and thickness of the orthodontic wire (10) being used. In addition, since the support of the orthodontic wire (10) is completed simply by sliding the cap member (200), the convenience of the practitioner and / or patient throughout the entire treatment process is also increased.

[0411] Drawing 20 is a drawing showing an orthodontic wire being placed and supported between a base member and a cap member of an orthodontic bracket according to the present invention, and Drawing 21 is a drawing showing a side view of the orthodontic bracket of Drawing 20.

[0412] When the fastening between the base member (100) and the cap member (200) is completed through the processes (a), (b), and (c) of the drawing 19 discussed above, the present invention performs an orthodontic operation of moving the teeth (T) by using the orthodontic force provided through the orthodontic wire (10) arranged between the base member (100) and the cap member (200). Specifically, the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) slide along the 1-1 base fastening member (180) and the 1-2 base fastening member (190) of the base member (100) and then snap-fit ​​fastening is performed at their ends, thereby fastening the base member (100) and the cap member (200), and the orthodontic wire (10) is supported through the wire slot (WS) formed by the combination of the cap member (200) and the base member (100). For reference, the second wire slot (210) of the cap member (200) can be formed in a size and shape corresponding to the size and shape of the orthodontic wire (10) used so as to provide an appropriate interval, and when the orthodontic wire (10) is replaced, the cap member (200) in which the second wire slot (210) having a shape and size corresponding to the replaced orthodontic wire (10) is formed can be replaced and used.

[0413] Through this, the present invention has the effect of supporting easy use of an appropriate orthodontic wire throughout the entire process of orthodontic treatment.

[0414] Drawing 22 is a drawing showing a cap member with an identification mark attached to a base member of the present invention.

[0415] As previously discussed, the present invention is characterized in that the two members are joined through slide engagement and snap-fit ​​engagement by sliding the cap member (200) relative to the base member (100). In order to help orthodontists, dentists, etc. easily identify in which direction the cap member (200) should be moved and what shape the second wire slot (210) formed in the cap member (200) is, an identification mark (290) may be formed in relief on the 2-2 surface (200-2) of the cap member (200). For example, if the identification mark (290) is displayed in a semicircular shape, this may mean that the cross-section of the second wire slot (210) of the cap member (200) is formed in a semicircular shape, and the direction in which the curved portion of the semicircular shape faces may indicate the direction in which the two members should be slid to be joined with the base member (100). Through this, the user of the present invention, such as the correction, can easily check the shape and slide movement direction of the second wire slot (210) and attach it to the base member (100). In other words, it is possible to prevent mistakes or errors in selecting and attaching the cap member (200) in advance.

[0416] So far, the overall appearance and simple combination and fastening method of the orthodontic bracket (1000) according to the present invention have been confirmed, and below, the detailed configuration of the base member (100) constituting the orthodontic bracket according to the present invention will be examined in more detail.

[0417] Drawing 23 is a drawing showing the overall appearance of the base member constituting the present invention.

[0418] The base member (100) that is attached to the tooth (T) and serves as a foundation for the cap member (200) to be combined has a first-first surface (100-1) that is used when attaching to the tooth using a bonding agent such as resin (RE) and a first-second surface (100-2) that comes into contact with the cap member (200), and a slot protrusion (211) formed along the longitudinal direction (X) of the second wire slot (210) of the cap member (200) and a first wire slot (110) that serves to accommodate the orthodontic wire (10) may be formed on the first-second surface (100-2). The first wire slot (110) of the base member (100) supports the orthodontic wire (10) at an appropriate interval together with the second wire slots (210) of various sizes and shapes formed in the cap member (200), thereby efficiently transmitting the orthodontic force provided by the orthodontic wire (10) to the teeth (T). This will be examined in more detail with reference to the drawings below. For reference, the first wire slot (110) of the base member (100) and the second wire slot (210) may be formed to have the same length, and may be formed to accommodate 20 to 50 percent of the cross-sectional area of ​​the orthodontic wire (10) to be placed therein. In addition, the cross-section of the first wire slot (110) is formed in a semicircular shape so that a curved surface is formed in the width direction (Y), and the curvature value of this curved surface is smaller than the curvature value of the curved surface of the second wire slot (210) of the cap member (200), and the depth value can be formed to be larger than the diameter value of the orthodontic wire having a circular cross-section.

[0419] Drawings 24 and 25 are drawings showing the first and second surfaces of the base member constituting the present invention.

[0420] On both sides of the first wire slot (110) of the base member (100), a first-first base fastening member (180) and a first-second base fastening member (190) may be formed along the longitudinal direction (X). These first-first base fastening members (180) and first-second base fastening members (190) may play a role in supporting fastening in a slide manner and a snap-fit ​​manner with the cap member (200). Specifically, the 1-1 base fastening member (180) may include a 1-1 rail portion (181) which is an area that supports a slide-type fastening with the cap member (200) and a 1-1 groove portion (182) which is an area that supports a snap-fit-type fastening with the cap member (200), and the 1-2 base fastening member (190) may include a 1-2 rail portion (191) which is an area that supports a slide-type fastening with the cap member (200) and a 1-2 groove portion (192) which is an area that supports a snap-fit-type fastening with the cap member (200). For reference, the lengths of the 1-1 base fastening member (180) and the 1-2 base fastening member (190) formed in this manner may be formed to be the same as the length of the first wire slot (110), and the width value of the first wire slot (110) may be greater than the width value of the second wire slot (210) of the cap member (200).

[0421] Drawings 26 and 27 are drawings showing the appearance of the base member in the direction in which the cap member slides.

[0422] The cap member (200) constituting the present invention slides along the longitudinal direction (indicated by 'X' in the drawing) and is fastened to the base member (100). Drawings 26 and 27 are drawings showing the appearance (left side) of the base member (100) at the portion where the cap member (200) slides.

[0423] Through the drawing, it can be confirmed that a first wire slot (110) is formed in the center along the width direction (indicated as 'Y' in the drawing) of the base member (100), and it can be confirmed that a first-first base fastening member (180) and a first-second base fastening member (190) are formed on both sides of the first wire slot (110) to support a slide-type and a snap-fit-type fastening with the cap member (200). More specifically, based on the width direction, the ends of the structures for fastening the first-first base fastening member (180) and the first-second base fastening member (190) may be formed in a hook shape facing outward, outside, of the base member (100). That is, the cross-sections of the first-first base fastening member (180) and the first-second base fastening member (190) when viewed from the side may be formed in a hook shape. In other words, since the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) move along the 1-1 base fastening member (180) and the 1-2 base fastening member (190) like a rail and enter the base member (100), the end of the structure for slide fastening of the 1-1 base fastening member (180) and the 1-2 base fastening member (190) can be expressed as being formed in a hook-shaped rail shape facing outward of the base member based on the width direction. For reference, the part where the 2-1 cap fastening hole (220) of the cap member (200) is inserted may be referred to as the 1-1 space (171), and the part where the 2-2 cap fastening hole (230) is inserted may be referred to as the 1-2 space (172). These spaces may be formed in the shape of '┌', '└ ' with an undercut formed below the 1-1 base fastening hole (180) and the 1-2 base fastening hole (190) for stable fastening of the cap member (200) and the base member (100).In addition, the 1-1 space (171) and the 1-2 space (172) can be used as spaces in which an orthodontic auxiliary wire (40) providing additional corrective force is fixed and used. This will be described in more detail with reference to the drawings below.

[0424] Drawing 28 is a drawing showing the appearance of the base member on the opposite side of the direction in which the cap member slides.

[0425] In order to snap-fit ​​fastening with the cap member (200), the first-first base fastening opening (180) and the first-second base fastening opening (190) of the base member (100) may be formed with a first-first groove (182) and a first-second groove (192), respectively, and the second-first cap fastening opening (220) of the cap member (200) may be formed in the first-first base fastening opening (180) and the first-second base fastening opening (190) on the opposite side of the slide entry point. In more detail, the ends of the first-first base fastening member (180) and the first-second base fastening member (190) are formed to be slightly raised so that the first-first groove portion (182) and the first-second groove portion (192) can be formed with an undercut therebelow, and the second-first clasp (222) and the second-second clasp (232) of the cap member (200) are caught here, thereby forming a snap-fit ​​type connection. For reference, the term "end" used in the process of explaining the shape of the first-first base fastening member (180) and the first-second base fastening member (190) refers to the end of a portion formed by extending from the body, and can be understood to be used in a meaning including referring to the direction in which the end is facing.

[0426] In this way, the present invention double-joins and fastens the base member (100) and the cap member (200) through a slide method and a snap-fit ​​method, thereby preventing the cap member (200) from being unintentionally detached or released from the base member (100), thereby ensuring that the joint is stably maintained throughout the entire process of orthodontic treatment.

[0427] Drawing 29 is a drawing showing the appearance of the unevenness formed on the first surface of the base member constituting the orthodontic bracket according to the present invention, and Drawing 30 is a drawing showing the appearance of the pattern formed on the first surface of the base member constituting the orthodontic bracket according to the present invention.

[0428] The first-first surface (100-1) of the base member (100) constituting the present invention may have protrusions formed to increase the contact area with a bonding agent such as resin (RE) so as to be effectively and more firmly attached to the surface of the tooth (T), and Drawing 29 is a drawing showing an example of protrusions formed for this purpose. Furthermore, the first-first surface (100-1) of the base member (100) may have a pattern formed to increase the contact area with a bonding agent such as resin (RE), as shown in Drawing 30. In this pattern, a wall pattern (176) may be formed to prevent the bonding agent from leaking out of the base member (100), particularly to prevent it from leaking to the left and right sides where the cap member (200) slides in. This wall pattern (176) may be formed entirely along the edge of the 1-1 surface (100-1), but may not be formed in some areas. A third open portion (173) and a fourth open portion (174) may be formed in the portion facing the 1-3 surface (100-3), which is the upper portion of the base member (100), and in the portion facing the 1-4 surface (100-4), which is the lower portion, so that the bonding agent can escape to the outside. By forming a pattern of this structure on the 1-1 surface (100-1) of the base member (100), the present invention prevents the bonding agent buried in the 1-1 surface (100-1) from overflowing into the space where the slide and snap fit bonding is made, while allowing the excess applied bonding agent to move to the 1-3 surface (100-3) and the 1-4 surface (100-4) above and below the base member (100), so that it can be used for attachment of the base member (100) to the surface of the tooth (T).For reference, the first surface (100-1) of the base member (100) may be formed to be slightly concave in the center so that it can be well attached to the surface of a tooth (T) that is formed to be slightly convex, and an identification mark (175) may be formed in a negative or positive shape so that an orthodontist, dentist, or other practitioner can easily check the type of base member (100) being used. However, it is preferable to form it in a positive or negative shape, but the identification mark (175) is not necessarily limited to being formed in a positive or negative shape.

[0429] Hereinafter, the cap member (200), which is another component of the orthodontic bracket (1000) according to the present invention, will be examined in detail one by one.

[0430] Drawing 31 is a drawing showing a side view of a cap member constituting the present invention.

[0431] The drawing shows the left side of the cap member (200), and the cap member (200) constituting the orthodontic bracket (1000) according to the present invention can be formed to include a second-first surface (200-1) that contacts the base member (100), and a second wire slot (210) formed on the second-first surface (200-1). In addition, the cap member (200) can be formed to further include a second-first cap fastening member (220) and a second-second cap fastening member (230) to support a slide and snap-fit ​​fastening with the base member (100) on both sides of the second wire slot (210). Specifically, the 2-1 cap fastening member (220) is formed in a hook shape such that the end of the structure for fastening with the 1-1 base fastening member (180) of the base member (100) faces the inside, the inner side of the cap member (200) based on the width direction, and this may be the same for the 2-2 cap fastening member (230). In other words, the 2-1 cap fastening member (220) may be formed as a hook-shaped rail whose cross-section is formed in the shape of '┌' or '└' such that the end of the structure for slide fastening faces the inside, the center of the cap based on the width direction, and this may be the same for the 2-2 cap fastening member (230). Here, the 'inside' and 'inner side' of the cap member (200) refer to the direction toward the center of the cap member (200), and the 'end' can be understood to refer to the end formed by extending from the body and the direction in which the end is directed. For reference, the opposite side of the 2-1 surface (200-1) that comes into contact with the base member (100) can be referred to as the 2-2 surface (200-2), on which an identification mark (290) implicitly indicating the slide entry direction and the shape of the second wire slot (210) described above can be formed in relief or intaglio.

[0432] Drawing 32 is an enlarged view showing a second wire slot portion of a cap member constituting the present invention.

[0433] A second wire slot (210) may be formed on the 2-1 surface (200-1) of the cap member (200) to support an orthodontic wire (10) and to transmit the orthodontic force provided by the orthodontic wire (10) to the teeth (T), and slot protrusions (211) may be formed along the longitudinal direction on both sides of the second wire slot (210). The second wire slot (210) may be formed in various shapes depending on the shape and diameter of the orthodontic wire (10) to be supported, and the drawing shows a second wire slot (210) formed in a semicircular shape. Here, the slot protrusion (211) supports the orthodontic wire (10) and plays an important role in the process of transmitting the orthodontic force provided by the orthodontic wire (10) to the teeth (T). Specifically, it can play a role in supporting the orthodontic wire (10) while maintaining an appropriate gap without it coming off through the force transmitted when the base member (100) and the cap member (200) are combined. Accordingly, even if the second wire slot (210) has only a semicircular shape, the orthodontic wire (10) can be stably supported through the assistance of the slot protrusion (211) and the first wire slot (110). For reference, the curvature value of the curved surface of the second wire slot (210) may be greater than the curvature value of the curved surface of the first wire slot (110) of the base member (100).

[0434] In this way, the present invention can be used by selecting a cap having an appropriate second wire slot (210) according to the shape and thickness of the orthodontic wire (10) used, so that the effect of effectively transmitting the restorative force of the orthodontic wire to the teeth and periodontium can be achieved.

[0435] Drawing 33 is a drawing showing the side surface of a portion of a cap member constituting the present invention that slides into a base member.

[0436] Drawing 33 is a drawing showing the right side of the cap member (200), and when combined with the base member (100), this part comes into contact with the base member (100) first. A 2-1 latch (222) for snap-fit ​​fastening may be formed at a portion where the slide entry begins from the 2-1 cap fastening opening (220) of the cap member (200), and similarly, a 2-2 latch (232) for snap-fit ​​fastening may be formed at a portion where the slide entry into the base member (100) begins from the 2-2 cap fastening opening (230). This 2-1 latch (222) is caught in the 1-1 groove portion (182) formed in an undercut structure in the 1-1 base fastening opening (180) of the base member (100) to fasten in a snap-fit ​​manner, and this may also be the same for the 2-2 latch (232). More specifically, the cap member (200) is made of elastic resin, and when the cap member (200) starts to slide with the base member (100), the 2-1 clasp (222) of the cap member (200) moves slightly downward by the 1-1 base fastening member (180) of the base member (100), and as the sliding movement continues, when it meets the 1-1 groove (182) of the 1-1 base fastening member (180), the 2-1 clasp (222) moves upward, thereby forming a snap-fit ​​fastening. And, this process can equally occur on the 2-2 clasp (232) side of the cap member (200). Through this structure, the orthodontic bracket (1000) according to the present invention can effectively support a stable connection between the base member (100) and the cap member (200). For reference, if necessary, the 2-1 latch (222) and the 2-2 latch (232) may not be formed, and the corresponding 1-1 groove (182) and the 1-2 groove (192) may not be formed. In this case, the connection between the base member (100) and the cap member (200) may be formed by a sliding method.In addition, if necessary, the 2-1 rail part (221) and the 2-2 rail part (231) may not be provided, and the corresponding 1-1 rail part (181) and the 1-2 rail part (191) may not be formed. In this case, the connection between the base member (100) and the cap member (200) may be made by fastening using a snap fit method.

[0437] Drawings 34 and 35 are drawings showing the 2-1 surface of the cap member constituting the present invention that comes into contact with the base member.

[0438] A second wire slot (210) may be formed along the longitudinal direction at the center of the cap member (200) constituting the present invention, and slot protrusions (211) that help support the orthodontic wire (10) may be formed on both sides thereof. Here, the lengths of the second wire slot (210) and the slot protrusions (211) may be formed to be the same. For reference, in the case of the drawing, the second wire slot (210) is formed to be smaller than the length of the cap member (200), but this is not limited thereto, and if necessary, the second wire slot (210) may be formed to be the same as the length of the cap member (200), and the lengths of the second wire slot (210) and the first wire slot (110) may also be formed to be the same.

[0439] A second-first cap fastening member (220) and a second-second cap fastening member (230) used for fastening and joining with the base member (100) can be formed on both sides of the second wire slot (210) and the slot protrusion (211). The second-first cap fastening member (220) can be formed by including a second-first rail portion (221) and a second-first latch (222). In addition, the second-second cap fastening member (230) can be formed by including a second-second rail portion (231) and a second-second latch (232). Looking at the roles of the detailed configuration in more detail, the 2-1 rail part (221) can perform a role of being connected to the 1-1 rail part (181) of the base member (100) in a sliding manner, and the 2-1 latch (222) can perform a role of being connected to the 1-1 groove part (182) of the base member (100) in a snap-fit ​​manner. In addition, similarly, the 2-2 rail part (231) can perform a role of being connected to the 1-2 rail part (191) of the base member (100) in a sliding manner, and the 2-2 latch (232) can perform a role of being connected to the 1-2 groove part (192) of the base member (100) in a snap-fit ​​manner. For reference, in the drawing, the length of the 2nd wire slot (210) is depicted as being shorter than the 2-1 cap fastening hole (220) or the 2-2 cap fastening hole (230), but if necessary, the lengths may be formed to be the same. For reference, the dotted arrows in the drawing show the direction in which the cap member (200) must move to engage with the base member (100).

[0440] A 2-1 protrusion (281) may be formed on the 2-3 surface (200-3) of the cap member (200) constituting the orthodontic bracket (1000) according to the present invention, and a 2-2 protrusion (282) may be formed on the 2-4 surface (200-4), which is the other side of the 2-3 surface (200-3). These 2-1 protrusions (281) and 2-2 protrusions (282) may be used to hang rubber bands such as power chains used to provide additional orthodontic force during orthodontic treatment. In addition, in order to easily hang the power chain, the sizes of the 2-1 protrusions (281) and 2-2 protrusions (282) may be formed to be somewhat smaller than the diameter of the hole formed in the power chain, and the entrance and the end of the 2-1 protrusion (281) and the 2-2 protrusion (282) may be formed to be slightly narrower than the inside and the inner side. For reference, these 2-1 protrusions (281) and 2-2 protrusions (282) are considerably smaller and have a smoother shape than the rubber band hook (21) of a conventional metal orthodontic device (20), so that the mucous membrane in the mouth can be prevented from being damaged by these protrusions or foreign substances such as food from being caught.

[0441] Drawing 36 is a drawing showing the 1-2 surface of the base member and the 2-1 surface of the cap member in contrast to each other when combined.

[0442] This drawing is a drawing comparing the detailed configuration of the first-second surface (100-2) of the base member (100) and the second-first surface (200-1) of the cap member (200), which are surfaces that come into contact with each other, in order to easily explain the process of joining the base member (100) and the cap member (200) to each other. Although it is a view from above, the second-first surface (200-1) of the cap member (200) is projected and shown for convenience of explanation.

[0443] Now, if we look at the role of each component in the process of joining the 1-2 side (100-2) of the base member (100) and the 2-1 side (200-1) of the cap member (200) in more detail, as the cap member (200) moves in the lateral direction (from left to right in the drawing) of the base member (100), the 2-1 latch (222) of the 2-1 cap fastener (220) comes into contact with the 1-1 rail portion (181) of the 1-1 base fastener (180) having a tapered edge, causing the 2-1 latch (222) to move downward. And as the force continues to be applied, the 2-1 latch (222) continues to move along the 1-1 rail portion (181) and meets the 1-1 groove portion (182). At this point, the 2-1 latch (222) rises upward and enters the 1-1 groove portion (182), thereby completing the fastening and combination of the cap member (200) and the base member (100). Specifically, the 2-1 latch (222) is inserted into the 1-1 groove portion (182), and the 2-1 rail portion (221) comes into contact with the 1-1 rail portion (181), thereby completing the fastening in the snap-fit ​​manner and the slide manner. Here, a wall may be formed on the far right side of the 1-1 home portion (182) to prevent continued movement of the 2-1 latch (222), or a wall may be formed on the 2-1 cap fastening member (220) at the end opposite to the entry direction to prevent further movement. In addition, the same process may be performed between the 2-2 cap fastening member (230) and the 1-2 base fastening member (190). Through this, the present invention can ensure stable coupling and fastening between the cap member (200) and the base member (100).For reference, in the process of combining the cap member (200) and the base member (100), a wire slot (WS) for supporting the orthodontic wire (10) is formed, in which the second wire slot (210), the slot protrusion (211), and the first wire slot (110) are also arranged. For this purpose, the width value of the first wire slot (110) can be made larger than the width value of the second wire slot (210) of the cap member (200).

[0444] Drawing 37 is a drawing showing the appearance of a second wire slot having a semicircular cross-section that supports an orthodontic wire in an orthodontic bracket according to the present invention.

[0445] The cross-section of the first wire slot (110) of the base member (100) constituting the present invention is formed in a semicircular shape. In addition, compared to the cap member (200) being changed to provide an appropriate slot depending on the orthodontic wire (10) being used, the shape of the first wire slot (110) does not change depending on the replacement of the orthodontic wire (10) since the base member (100) remains attached to the tooth (T). Nevertheless, the first wire slot (110) of the base member (100) is formed to have a depth value (D1) that is greater than the depth value (D2) of the second wire slot (210) and greater than the diameter value of the orthodontic wire having a circular cross-section, thereby effectively supporting the orthodontic wire (10) being placed. Furthermore, the first wire slot (110) has a width value (Y1) that is larger than the width value (Y2) of the second wire slot (210), and a curvature value of a curved surface formed in the width direction is also smaller than the curvature value of the second wire slot (210), thereby efficiently supporting the orthodontic wire (10) arranged between the first wire slot (110) and the second wire slot (210) at an appropriate interval. In particular, by accommodating the slot protrusion (211) of the cap member (200) in the first wire slot (110), almost all of the arranged orthodontic wire (10) is accommodated inside, and through this, even if a part of the second wire slot (210) is open, the orthodontic wire (10) can be efficiently supported through the first wire slot (110). Here, the first wire slot (110) can accommodate 20 to 50 percent of the cross-sectional area of ​​the orthodontic wire (10) therein, and the second wire slot (210) can accommodate 50 to 95 percent of the cross-sectional area of ​​the orthodontic wire (10) therein.For reference, a virtual surface where the 1-2 surface (100-2) of the base member (100) and the 2-1 surface (200-1) of the cap member (200) make contact can be referred to as a contact surface (CP), and although only the second wire slot (210) for one diameter is shown as an example in the drawing, if the diameter of the orthodontic wire (10) is changed, a cap member (200) having a corresponding second wire slot (210) can be selected and used. For example, the diameter of the cross-section of the second wire slot (210) can be selected in the range of 0.3 to 0.5 millimeters, or, in the case of supporting an orthodontic wire (10) having a circular cross-section, can be formed to be 0.8 to 1.2 millimeters larger than the diameter of the corresponding orthodontic wire (10). Alternatively, referring to an orthodontic textbook, the gap between the orthodontic wire (10) and the slot is 0.1 millimeters, which provides the lowest coefficient of friction and thus the optimal orthodontic force, so the second wire slot (210) may be formed so that the gap is 0.05 to 0.1 millimeters greater than the orthodontic wires (10) being placed.

[0446] By forming a wire slot with an appropriate optimal spacing between the first wire slot (110), the second wire slot (210), and the slot protrusion (211) around the orthodontic wire (10), the present invention can support the replacement and use of various orthodontic wires (10) according to the orthodontic treatment stage by replacing the cap member (200) while the base member (100) is attached to the teeth.

[0447] Drawing 38 is a drawing showing the appearance of a second wire slot having a rectangular cross-section that supports an orthodontic wire in an orthodontic bracket according to the present invention.

[0448] In the course of orthodontic treatment of teeth (T), in addition to orthodontic wires (10) having a circular cross-section, orthodontic wires having a square cross-section can also be used. Such orthodontic wires (10) can be used when there is a need to provide orthodontic force in the direction of torque to teeth. However, since conventional self-ligating brackets (30) or conventional metal orthodontic devices (20) are not easy to remove after being attached to teeth (T), the use of orthodontic wires (10) having a square cross-section must be prepared, and the use of the largest orthodontic wire (10) must also be prepared, so the slot must be prepared to be large in advance. As a result, there was a problem in that an appropriate distance from the orthodontic wire (10) could not be maintained, so that the orthodontic force was not properly transmitted to the teeth or was lost due to friction.

[0449] In contrast, the present invention can select and use a cap member (200) that supports an orthodontic wire (10) having a rectangular cross-section when it is necessary to use the same, thereby solving problems such as the gap being too large and the orthodontic force not being transmitted, and transmitting an appropriate orthodontic force transmitted by the orthodontic wire (10) to the teeth (T). Specifically, the second wire slot (210) used when supporting a rectangular orthodontic wire (10) but not requiring torque is formed so that a virtual line (IL) extending vertically from the bottom surface of the second wire slot (210) meets a virtual surface covering the upper portion of the first wire slot (110), i.e., a virtual surface formed by contact between the first-second surface (100-2) and the second-first surface (200-1), while being perpendicular to the contact surface (CP). When using an orthodontic wire (10) having a rectangular cross-section, the first wire slot (110) accommodates about 20 to 50 percent (%) of the cross-sectional area of ​​the orthodontic wire (10) therein. In addition, the second wire slot (210) having a rectangular cross-section in the width direction is formed to have a vertical (width) length of 0.4 to 0.6 millimeters and a horizontal (CP direction) length of 0.5 to 0.8 millimeters, thereby being able to accommodate about 50 to 95 percent of the cross-sectional area of ​​the orthodontic wire (10) therein. For reference, the slot protrusions (211) arranged on both sides of the second wire slot (210) can restrict the arranged orthodontic wire (10) from moving from the center position of the first wire slot (110) to an unwanted position, thereby preventing the frictional force between the orthodontic bracket (1000) according to the present invention and the orthodontic wire (10) from increasing.

[0450] Drawing 39 is a drawing showing the appearance of a second wire slot having a rectangular cross-section with an inclined cross-section that supports an orthodontic wire in an orthodontic bracket according to the present invention.

[0451] When torque needs to be applied in orthodontic treatment, a cap member (200) having a second wire slot (210) in an inclined rectangular shape can be selected and used. Looking at the shape of the second wire slot (210) of the cap member (200) in more detail, an imaginary line (IL) extending vertically from the bottom surface of the second wire slot (210) meets an imaginary surface covering the upper portion of the first wire slot (110) (an imaginary surface 'CP' formed by the contact of the first-second surface (100-2) and the second-first surface (200-1)) at an angle, so that the second wire slot (210) can be manufactured to have an inclined rectangular shape. The inclination formed by the imaginary line and the contact surface (CP) can be appropriately selected as needed, and can be selected in the range of 9 to 35 degrees.

[0452] In this way, the bracket according to the present invention enables the provision of an appropriate slot according to the size and shape of the orthodontic wire used in each stage of orthodontic treatment, thereby providing an appropriate orthodontic force to the teeth (T) in each treatment stage, thereby maximizing the treatment effect and shortening the treatment period. For reference, in drawings 37 to 39, the second wire slot (210) is shown to have a semicircle, square, or slanted square shape in order to support the orthodontic wire (10) having a circular or square cross-section. However, it should be noted that if the thickness and shape of the wire used are changed, the shape and size of the second wire slot (210) may also be changed together to appropriately support it. That is, the second wire slot (210) may be changed to an appropriate shape and size so that the gap between the orthodontic wire (10) used and the inner wall of the second wire slot (210) is maintained at approximately 0.1 millimeter.

[0453] Drawing 40 is a drawing showing an identification mark formed on the second-second surface of a cap member constituting the present invention and its role.

[0454] As previously described, the 2-2 side (200-2) of the cap member (200) constituting the present invention may be formed with an identification mark (290) indicating the shape and / or the slide entry direction of the second wire slot (210). Although not limited to, this identification mark (290) may be formed in relief, and the slide entry direction for fastening the cap member (200) to the base member (100) and the shape of the cross-section of the second wire slot (210) may be indicated and marked with a single identification mark (290). For example, when a right semicircle shape such as (a) in the drawing is indicated on the 2-2 side (200-2), it can inform the user of the correction device, etc., that the cross-section shape of the second wire slot (210) of the corresponding cap member (200) is a semicircle shape and that the slide entry direction should be moved from left to right. Similarly, in the case of a triangular shape such as (c) of the drawing, the shape of the cross-section of the second wire slot (210) is a 30-degree inclined square, and the slide entry direction for fastening with the base member (100) can be represented as the left-to-right direction as indicated by the dotted line of the drawing, which is the direction indicated by the triangle. In addition, in the case of a rectangular shape such as (b) of the drawing, the shape of the cross-section of the second wire slot (210) is a 15-degree inclined square, and the entry direction for slide and snap fit fastening can be represented as the left-to-right direction from the part where the identification mark (290) is indicated to the part where it is not.

[0455] In this way, the shape and slide direction of the second wire slot (210) of the cap member (200) can be predicted through the identification mark (290) formed on the cap member (200), thereby increasing the convenience of the user for correction, etc., and preventing mistakes from occurring in advance.

[0456] The following drawings 41 to 46 illustrate in more detail each step of the usage process of the orthodontic bracket (1000) according to the present invention through drawings.

[0457] Drawing 41 is an enlarged view showing the etched tooth surface.

[0458] In order to effectively attach the base member (100) constituting the present invention to the tooth (T), a process of etching (ET) the surface of the tooth (T) using a weak acid or the like may first be performed, and the drawing is a drawing showing an enlarged view of the surface of the tooth on which the etching has been performed. For reference, this etching (ET) is a preliminary measure to ensure that a bonding agent such as a resin, which will be used later for attaching the base member (100), penetrates well into the tooth (T).

[0459] Drawings 42 and 43 are drawings showing the process of attaching the base member constituting the present invention to the tooth surface.

[0460] After performing etching (ET) on the surface of the tooth (T), a process of applying a first resin (RE1) having good flowability to the surface of the etched (ET) tooth (T) can be performed, and a process of applying a second resin (RE2) having a higher viscosity than the first resin (RE1) to the 1-1 surface (100-1) of the base member (100) can be performed. Here, the 1-1 surface (100-1) of the base member (100) may have a pattern or unevenness previously formed so as to increase the contact area with the second resin (RE2), and if such a pattern or unevenness is not previously formed, etching may be performed before applying the second resin (RE2). Next, a process of moving the base member (100) to which the second resin (RE2) is applied to the tooth (T) and attaching it to the tooth (T) can be performed. This attachment process can be accomplished by using a light curing device to shine light onto the first resin (RE1) and the second resin (RE2), which are light-curing resins. By using the first resin (RE1) and the second resin (RE2) in a differentiated manner in this way, the present invention allows the base member (100) to be easily removed from the surface of the tooth (T) after the treatment is completed in the future.

[0461] Drawings 44 and 45 are drawings showing the process of fastening a cap member to a base member while an orthodontic wire is placed, and Drawing 46 is a drawing showing the completed support of an orthodontic wire through an orthodontic bracket according to the present invention.

[0462] As described above, after the attachment of the base member (100) is completed, an appropriate orthodontic wire (10) is selected and placed at each stage of orthodontic treatment, and then a cap member (200) having a second wire slot (210) capable of supporting the orthodontic wire (10) at an appropriate interval is selected and fastened to the base member (10), thereby transmitting the orthodontic force provided by the orthodontic wire (10) to the teeth (T). For reference, in the drawing, an orthodontic wire (10) having a circular cross-section is selected, and it can be confirmed that a cap member (200) having a second wire slot (210) having a semicircular cross-section is selected and used to support the orthodontic wire (10). However, if an orthodontic wire (10) of a different size and shape is selected, a cap member (200) having an appropriate second wire slot (210) to support the orthodontic wire (10) may be selected and used again.

[0463] Since the present invention can support slots with appropriate spacing according to the actively used wire, it can actively support the use of nickel-titanium wires that have weak elasticity but exert a weak and continuous force, and through this, the force provided by the nickel-titanium wire can also be effectively transmitted to the teeth. Accordingly, the number of replacements of the orthodontic wire (10) in orthodontic treatment for teeth (T) can be drastically reduced, thereby increasing the convenience of the patient and / or the orthodontist.

[0464] Drawings 47 and 48 are drawings showing an orthodontic auxiliary wire mounted in an open area of ​​a base member constituting the present invention to provide additional orthodontic force required for orthodontic treatment.

[0465] In the course of orthodontic treatment for teeth (T), there are cases where additional orthodontic force is required in addition to the orthodontic force provided by the orthodontic wire (10). In this case, the present invention can help transmit this additional orthodontic force to the teeth (T) by using the orthodontic auxiliary wire (40) through the 1-1 space (171) and the 1-2 space (172) of the base member (100). Specifically, in the area where additional orthodontic force transmission is required, the bound cap member (200) is removed, and the orthodontic auxiliary wire (40) is placed in the 1-1 space (171) or the 1-2 space (172) of the base member (100), and a temporary resin (TR) is applied thereon to fix the orthodontic auxiliary wire (40) thereon, thereby transmitting additional orthodontic force and traction force to the teeth (T). The temporary resin (TR) used here can be easily removed if it is necessary to re-attach the cap member (200) in the future.

[0466] In addition to the method of using a rubber band, the present invention can also support the use of an orthodontic auxiliary wire (40) using a base member (100) attached to a tooth (T) in this way, thereby enabling more efficient tooth (T) (dentition) orthodontic treatment.

[0467] Drawing 49 is a drawing schematically showing the concept of use of the orthodontic bracket according to the present invention.

[0468] Drawing 49 schematically shows the appearance of the orthodontic bracket (1000) according to the present invention described so far and the method of using the orthodontic bracket (1000) to be described later, and shows that various orthodontic wires (10) can be placed on one base member (100) attached to a tooth (T), and for this purpose, a cap member (200) having various second wire slots (210) can be selected and used.

[0469] In this way, by selecting various orthodontic wires (10) throughout the entire process of orthodontic treatment and effectively transmitting the orthodontic force provided by the orthodontic wires (10) to the teeth (T), the present invention can shorten the treatment period for orthodontic treatment of teeth (T) and minimize side effects such as root absorption.

[0470] Drawing 50 is a drawing showing the removal of the base member attached to the tooth.

[0471] Even when the base member (100) needs to be removed from the surface of the tooth (T) due to completion of orthodontic treatment of the tooth (T), the present invention can more easily remove it from the surface of the tooth (T) compared to a conventional self-ligating bracket (30) or a conventional metal orthodontic device (20). For example, in the process of removing a conventional bracket, the bracket may break, so it must be ground with a high-speed cutting tool, and the resin remaining on the surface of the tooth must also be ground, making the removal process difficult in many cases. However, the present invention helps the base member to be removed more easily by pulling the fastening member formed on the base member (100). This process can be carried out by pulling the 1-1 base fastening member (180) and the 1-2 base fastening member (190) of the base member (100), and a removal tool (RM) can be specially designed and used so that the 1-1 base fastening member (180) and the 1-2 base fastening member (190) can be pulled more efficiently. In particular, this removal method can be more efficient by applying and attaching resins having different viscosities between the resin applied to the tooth (T) and the resin applied to the 1-1 surface (100-1) of the base member (100) when attaching the base member (100) described above.

[0472] The orthodontic bracket (1000) according to the present invention can cleanly remove and detach the base member (100) from the surface of the tooth (T), thereby reducing the treatment time and increasing the convenience of the orthodontist or patient.

[0473] Drawings 51 to 54 are flowcharts showing a method of using an orthodontic bracket according to the present invention.

[0474] The present invention can be performed first, as a preliminary step for using the orthodontic bracket (1000) according to the present invention, by etching the surface of the tooth (T) using a weak acid or the like (S1-1). Specifically, etching can be performed on the surface of the tooth (T) to which the base member (100) is to be attached. Next, a process of applying a first resin (RE1) to the surface of the etched tooth (T) can be performed (S1-2), a process of applying a second resin (RE2) to the first-first surface (100-1) of the base member (100) can be performed (S1-3), and a process of attaching the base member (100) to which the second resin (RE2) is applied to the tooth (T) can be performed (S1-4). The reason for applying the first resin (RE1) and the second resin (RE2) in two parts is that the bonding force between the first resin (RE1) and the tooth (T) and the bonding force between the second resin (RE2) and the base member (100) are greater than the bonding force between the first resin (RE1) and the second resin (RE2), so that when the base member (100) is removed from the surface of the tooth (T) in the future, the first resin (RE1) and the second resin (RE2) are separated, allowing the base member (100) to be easily detached.

[0475] After the base member (100) is attached to the tooth (T) in this way, a practitioner such as an orthodontist or dentist can go through a process of determining whether an orthodontic auxiliary wire (40) is necessary (S1-5). Here, if it is determined that an orthodontic auxiliary wire (40) is not necessary, a process of placing an orthodontic wire (10) between the base member (100) and the cap member (200) can be performed (S1-6), and a process of fastening the cap member (200) to the base member (100) can be performed (S1-7). For reference, in the above process, the orthodontic wire (10) is placed between the first wire slot (110) of the base member (100) and the second wire slot (210) of the cap member (200), and the fastening of the cap member (200) and the base member (100) can be performed through a slide method and / or a snap fit method. Additionally, in the case of an embodiment in which the cap member (200) and the base member (100) are connected in a hinge manner, snap-fit ​​fastening can be achieved by rotating the cap member (200) toward the base member (100) around the hinge axis.

[0476] In this way, when the orthodontic bracket (1000) according to the present invention is mounted on the tooth (T) and used, the practitioner such as an orthodontist or dentist can go through a process of checking whether the orthodontic wire (10) needs to be replaced during the orthodontic treatment of the tooth (T) (S1-8). Here, if it is determined that the orthodontic wire (10) needs to be replaced, a process of releasing the cap member (200) from the base member (100) can be performed (S1-9), and then the orthodontic wire (10) can be replaced while going through a process of removing it (S1-19). Here, the orthodontic wire (10) to be replaced may have a diameter, etc., larger than the previous one, and therefore, the second wire slot (210) of the newly mounted cap member (200) may be selected to have a larger cross-sectional area than the second wire slot (210) of the removed one. The specific process of release or detachment between the cap member (200) and the base member (100) will be examined through other drawings.

[0477] Here, if it is determined that correction of the orthodontic wire (10) is not necessary, then a process may be performed to determine whether treatment using an Invisalign or transparent orthodontic device is necessary (S2-1). At this stage, if it is determined that it is necessary to utilize an Invisalign or the like, a process may be performed in which the cap member (200) is released from the base member (100) by the practitioner (S2-2) and a process may be performed in which the orthodontic wire (100) is removed (S2-3). Next, a process may be performed in which a temporary resin (TR) is applied to the 1-2 surface (100-2) of the base member (100) to fill the 1-1 space (171), the 1-2 space (172) of the base member (100) (S2-4), and a process may be performed in which a frame for Invisalign or transparent orthodontic treatment is mounted on the teeth (S2-5). In this way, the base member (100) for Invisalign, to which temporary resin (TR) is applied, can function as an attachment. Alternatively, instead of applying temporary resin (TR), a method in which a thin cap member for attachment is mounted on the base member (100) may be utilized. For reference, orthodontic treatment using Invisalign is less effective than orthodontic treatment using brackets in terms of movement and arrangement of teeth (T), but is effective in expanding the dental arch, etc. In this way, the present invention can achieve the effect of achieving more effective orthodontic treatment by selecting the advantages of orthodontic treatment using brackets and the advantages of treatment using a transparent orthodontic device such as Invisalign by enabling it to be used as an attachment without removing the base member (100).

[0478] Next, the orthodontic device goes through a process of confirming whether treatment using an Invisalign or transparent orthodontic device has been completed (S2-6), and if it is determined that treatment using an Invisalign or the like is no longer necessary, the frame for the Invisalign or transparent orthodontic device is removed from the teeth by the orthodontic device (S2-7), and the temporary resin (TR) applied to the base member (100) or the cap member for the attachment may be removed (S2-9). For reference, since the temporary resin (TR) applied to the base member (100) is not chemically bonded to the base member (100) very hard like a bonding agent even when hardened, it can be removed using tweezers or the like.

[0479] Next, a process of determining whether the orthodontic treatment (T) is completed is performed (S2-9), and if further orthodontic treatment is needed, the process moves to step 'A' of drawing 51 to continue the treatment process. In this process, if the orthodontist determines that an orthodontic auxiliary wire (40) is necessary (S1-5), in order to support the use of the orthodontic auxiliary wire (40), first, the cap member (200) is released from the base member (100) (S3-1), and a process of placing the orthodontic auxiliary wire (40) by utilizing the 1-1 space (171) of the base member (100) may be performed (S302). Specifically, the orthodontic auxiliary wire (40) may be placed in an area where the 2-1 cap fastening member (220) and / or the 2-2 cap fastening member (230) of the base member (100) are inserted. Here, in order to prevent the orthodontic auxiliary wire (40) from coming off, a process of applying temporary resin (TR) over the orthodontic auxiliary wire (40) can be further performed (S3-3).

[0480] In this way, while orthodontic treatment is being performed using the orthodontic auxiliary wire (40), the practitioner, such as the orthodontist, may decide to stop using the orthodontic auxiliary wire (40) (S3-4). In this case, the temporary resin (TR) applied over the orthodontic auxiliary wire (40) may be removed using tweezers or the like (S3-5), and the orthodontic auxiliary wire (40) placed in the 1-1 space (171) and / or the 1-2 space (172) may be removed (S3-6).

[0481] During this process, the orthodontist can perform a process of deciding whether or not to finally end the orthodontic treatment (S3-7), and if a decision to end the orthodontic treatment is made here, all components used in the orthodontic treatment, including the base member (100), are removed from the surface of the tooth (T) through a process (S4-1), and the treatment process can be ended.

[0482] In this way, the present invention can support the easy use of an appropriate orthodontic wire throughout the entire process of orthodontic treatment, and can also support the use of a transparent orthodontic device such as Invisalign at a stage where the use of such a device is required, thereby maximizing the effectiveness of orthodontic treatment, shortening the orthodontic treatment period, and improving the convenience of patients and practitioners.

[0483] Drawing 55 is a flowchart showing the process of combining the base member and cap member constituting the present invention.

[0484] The process of fastening the base member (100) and the cap member (200) described in Drawing 51 can be carried out in detail through a process in which the cap member (200) starts to slide in from the side of the base member (100) (S5-1), the cap member (200) continuously moves to complete the slide entry, and the snap fit fastening of the cap member (200) and the base member (100) is completed (S5-2). More specifically, the fastening can be carried out in such a way that the 2-1 clasp (222) and the 2-2 clasp (232) of the cap member (200) receive force while riding the 1-1 base fastening member (180) and the 1-2 base fastening member (190) and move downward, and while continuously moving, they meet the 1-1 groove (182) and the 1-2 groove (192) and move upward to fit into the grooves, thereby performing the snap fit fastening. Or, depending on the embodiment, the slide entry may not be performed and the fastening may be performed in a snap-fit ​​manner, or the fastening may be performed in a snap-fit ​​manner according to rotation. Specifically, in the case of the orthodontic bracket (1000) according to another embodiment, the fastening may be performed in a snap-fit ​​manner by a force applied when the cap member (200) moves toward the base member (100), and in the case of another embodiment, the fastening may be performed in a snap-fit ​​manner by a force applied when the cap member (200) connected in a hinge manner rotates toward the base member (100). The detailed appearance of this embodiment will be specifically confirmed through the drawings below.

[0485] In this way, the present invention has the effect of increasing convenience of use and improving stability during the entire process of orthodontic treatment by combining the base member and the cap member constituting the orthodontic bracket (1000) through a slide and / or snap fit method.

[0486] Drawing 56 is a flowchart showing the process of releasing the base member and cap member constituting the present invention.

[0487] The release of the base member (100) and the cap member (200) can be performed in the reverse order of the bonding and joining process, which can be performed from the process in which the 2-1 latch (222) and the 2-2 latch (232) of the cap member (200) are detached from the 1-1 groove (182) and the 1-2 groove (192) of the base member (100) (S6-1). Here, the process of detaching the 2-1 latch (222) from the 1-1 groove (182) or detaching the 2-2 latch (232) from the 1-2 groove (192) can be performed using a specially designed tool. Next, the cap member (200) slides in the opposite direction to the direction in which it was slid in and is detached from the base member (100), thereby detaching the base member (100) and the cap member (200) constituting the present invention from each other (S6-2). For reference, in another embodiment, the snap-fit ​​connection between the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) may be released in such a manner that the cap member (200) moves inward of the cap member (200) and then moves away from the base member (100), and in another embodiment, the connection between the 2-1 cap fastening member (220) of the cap member (200) may be released in such a manner that the cap member (200) rotates in a direction away from the base member (100) around an axis connected in a hinge manner after moving inward of the cap member (200). Details of the orthodontic bracket (1000) according to another embodiment and another embodiment will be specifically confirmed through the drawings below.

[0488] The orthodontic bracket (1000) according to the present invention can be easily combined and released, so that an orthodontist or other practitioner can easily replace or remove the cap member (200) when performing tasks such as replacing an orthodontic wire (10).

[0489] Drawing 57 is a drawing showing the overall appearance of another embodiment of the orthodontic bracket of the present invention.

[0490] Another embodiment of the orthodontic bracket (1000) according to the present invention is largely composed of a base member (100) and a cap member (200), and the roles of the base member (100) and the cap member (200) are the same as in the previous embodiment in that they transmit the orthodontic force provided by the orthodontic wire (10) to the teeth (T) through a wire slot (WS) formed by combining and fastening each other. In addition, the cap member (200) coupled to the base member (100) can be replaced with another cap member (200) during the orthodontic treatment of the teeth (T) and can be used the same way. However, there is a change in the structure for fastening the base member (100) and the cap member (200) in a snap-fit ​​manner, and this part will be examined in more detail with reference to the drawings below. For reference, the base member (100) and cap member (200) constituting the bracket can be formed of a resin including engineering plastic, and specifically, TR 90 having high durability and safety can be selected and used.

[0491] Drawing 58 is a drawing showing a process of combining a cap member and a base member in another embodiment of the orthodontic bracket of the present invention.

[0492] In the orthodontic bracket (1000) of the embodiment discussed above, the slide and snap-fit ​​connection with the base member (100) is continuously achieved by sliding the cap member (200) laterally, whereas in another embodiment of the orthodontic bracket (1000), the cap member (200) is moved in the direction of the arrow and a pressing force is applied, thereby fastening the cap member (200) and the base member (100) in a snap-fit ​​manner. Through this, the orthodontic bracket and the method of using the same according to another embodiment of the present invention can achieve the effect of further increasing the convenience of use. The detailed configuration of the cap member (200) and the detailed configuration of the base member (100) that enable such snap-fit ​​connection will be confirmed in more detail through the following drawings.

[0493] Drawing 59 is a drawing showing another embodiment of the orthodontic bracket of the present invention as viewed from the side.

[0494] In the case of the orthodontic bracket (1000) of another embodiment, the base member (100) and the cap member (200) are fastened together to form a wire slot (WS), and the orthodontic force provided by the orthodontic wire (10) is transmitted to the tooth (T) using this wire slot (WS) so that the tooth (T) moves in the desired direction. For reference, in the drawing, 'Y' indicates the width direction, 'Z' indicates the height direction, and 'X' indicates the length direction. For reference, the orthodontic bracket (1000) can be manufactured in various sizes as long as it can be attached to the surface of the tooth (T) and support the orthodontic wire (10), but for example, it can be manufactured in a size of 3 to 4 millimeters in width, 3 to 4 millimeters in length, and 2 to 3 millimeters in height.

[0495] Drawing 60 is a drawing showing the overall appearance of a base member constituting another embodiment of the orthodontic bracket of the present invention.

[0496] According to another embodiment, the base member (100) is also attached to the tooth (T), and the role of transmitting the force provided by the orthodontic wire (10) to the tooth (T) together with the cap member (200) coupled thereon is the same as the role of the base member (100) described above. However, the detailed configuration for forming a snap-fit ​​connection with the cap member (200) in a more convenient manner is different, and for this purpose, the base member (100) may have a 1-1 base fastening member (180) formed on the other side of the first wire slot (110), and a 1-2 base fastening member (190) formed on one side of the first wire slot (110). In addition, a 1-1 protrusion (193) may be formed on both sides of the first wire slot (110) of the base member (100), a 1-3 surface, and a 1-2 protrusion (194) may be formed on the 1-4 surface. These 1-1 protrusions (193) and 1-2 protrusions (194) may be used for hanging a rubber band used as an auxiliary aid in correcting teeth (T).

[0497] Drawing 61 is a drawing showing a side view of a base member constituting another embodiment of the orthodontic bracket of the present invention.

[0498] The base member (100) constituting another embodiment of the orthodontic bracket (1000) of the present invention may be formed with a first-first surface (100-1) used for attachment to a tooth (T), and a first-second surface (100-2) in a direction in contact with the cap member (200), and as described above, it can be confirmed that a first-first base fastening member (180) and a first-second base fastening member (190) are formed on both sides of the first wire slot (110). More specifically, the first-first base fastening member (180) may be formed in a manner that penetrates from the first-second surface (100-2) to the first-third surface, and the first-second base fastening member (190) may be formed in a manner that penetrates from the first-second surface (100-2) to the first-fourth surface. And, when the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) are inserted here, snap fit fastening is achieved.

[0499] Drawing 62 is a drawing showing a view from the first to third sides of a base member according to another embodiment of the orthodontic bracket of the present invention.

[0500] Looking at the 1-3 side of the base member (100), it can be seen that the 1-1 base fastening hole (180) is formed to penetrate the 1-3 side and open to the outside, and the end of the 2-1 cap fastening hole (220) of the cap member (200) is pushed out through this, so that the 1-1 base fastening hole (180) and the 2-1 cap fastening hole (220) are fastened to each other. This method and structure can be formed in the same way on the 1-4 side, which is the opposite side of the base member (100).

[0501] Drawing 63 shows a view of the first and second surfaces of a base member according to another embodiment of the orthodontic bracket of the present invention.

[0502] As described above, it can be confirmed through the drawing that the 1-1 base fastening hole (180) and the 1-2 base fastening hole (190) are formed on both sides of the 1st wire slot (110) formed near the center in the width direction (Y) of the base member (100). More specifically, it can be confirmed that the 1-1 base fastening hole (180) is formed in a manner that penetrates from the 1-2 side (100-2) to the 1-3 side on the other side of the 1st wire slot (110), and it can be confirmed that the 1-2 base fastening hole (190) is formed in a manner that penetrates from the 1-2 side (100-2) to the 1-4 side on one side of the 1st wire slot (110). Through this structure, the present invention can support more convenient fastening and coupling between the cap member (200) and the base member (100).

[0503] Drawing 64 shows a view of the first side of another embodiment of the base member of the present invention.

[0504] The first-first surface (100-1) of the base member (100) is a surface that serves to be attached to the tooth (T), and may be formed concavely to facilitate attachment to the tooth (T). In addition, a bonding groove (195) or pattern may be formed on the first-first surface (100-1) to increase the contact area with the bonding agent. Through this structure, the present invention can stably attach the base member (100) to the surface of the tooth (T) and prevent the bonding agent from overflowing to the outside.

[0505] Drawing 65 shows the overall appearance of a cap member according to another embodiment of the orthodontic bracket of the present invention.

[0506] According to another embodiment of the present invention, a cap member (200) may be provided with a second-first cap fastening member (220) and a second-second cap fastening member (230) for fastening to a base member (100), and a second wire slot (210) may be formed between them to support an orthodontic wire (10) to be placed therebetween. For reference, the second wire slot (210) may be formed to have a rectangular cross-section, and may be manufactured to have a slightly inclined shape (3 degrees to 20 degrees) to apply torque during orthodontic treatment.

[0507] Drawing 66 is a side view drawing showing another embodiment of the cap member of the present invention, and Drawing 67 is a drawing showing the 2nd-3rd side of the cap member of the present invention.

[0508] The cap member (200) may be provided with a second-first surface (200-1) facing the base member (100) and in contact with the base member (100), and a second-second surface (200-2) opposite the second-first surface (200-1), and a second wire slot (210) may be formed at the center of the width direction (Y) of the second-first surface (200-1). In addition, slot protrusions (211) may be formed on both sides of the second wire slot (210) along the longitudinal direction of the second wire slot (210).

[0509] On the other side of the second wire slot (210), a 1-1 base fastening hole (180) of the base member (100) and a 2-1 cap fastening hole (220) for fastening in a snap fit manner may be formed, and on one side of the second wire slot (210), a 1-2 base fastening hole (190) of the base member (100) and a 2-2 cap fastening hole (230) for supporting fastening in a snap fit manner may be formed. Looking at the structure for snap-fit ​​fastening in more detail, the end of the 2-1 cap fastening member (220) is formed to face the outside of the cap member (200) based on the width direction (Y), and the end of the 2-2 cap fastening member (230) is also formed to face the outside of the cap member (200) based on the width direction, so that when the cap member (200) is pushed into the base member (100), this part moves inward for a moment and then fastens with the 1-1 base fastening member (180) of the base member (100) opened to the 1-3 side and the 1-2 base fastening member (190) of the base member (100) opened to the 1-4 side, thereby forming a snap-fit ​​fastening. Additionally, the 2nd wire slot (210) may be formed so that its cross-section has a rectangular shape. Specifically, a virtual surface (IP) parallel to the inner side wall of the second wire slot (210) may be made to meet an virtual surface passing through the 2-2 surface of the cap member (200) at an angle so that the second wire slot (210) has a cross-section of an inclined rectangle or parallelogram, and the angle may be selected in the range of 3 to 20 degrees. By forming the second wire slot (210) to have such an inclined rectangle shape, the present invention can effectively provide the torque force required in the orthodontic process to the teeth (T). For reference, the vertical length value of the second wire slot (210) having a rectangular cross-section in the width direction may be 0.3 to 0.6 millimeters, and the longer horizontal length value among the horizontal sides may be selected in the range of 0.5 to 0.8 millimeters.

[0510] Drawing 68 shows a second-first surface of a cap member according to another embodiment of the present invention.

[0511] It can be confirmed that a second wire slot (210) is formed at the center of the width direction (Y) of the 2-1 side (200-1) of the cap member (200), and it can be confirmed that slot protrusions (211) are formed on both sides thereof, and the second wire slot (210) can be formed to accommodate 45 to 95% of the orthodontic wire (10) arranged inside based on the cross-sectional area. For reference, the cap member (200) according to another embodiment of the present invention is used for the arrangement, horizontal alignment, and angle adjustment of anterior teeth. When the cross-section of the second wire slot (210) of the cap member (200) in the width direction is square, it is mainly used for the angle adjustment of the tooth (T) through torque application, and the cap member (200) having the second wire slot (210) whose cross-section is a semicircle, which will be confirmed later, can be mainly used for the arrangement of the tooth (T) in the initial stage of the orthodontic process. In this way, the present invention can shorten the period of orthodontic treatment and increase the effectiveness by supporting the selection and use of various brackets depending on the position of the tooth (T), orthodontic treatment, and timing.

[0512] Drawing 69 shows the overall appearance of a cap member according to another embodiment of the present invention.

[0513] A cap member (200) according to another embodiment of the present invention is similar to the cap member (200) of the other embodiment described above in many parts, but differs in that a curved surface is formed inside so that the cross-sectional shape of the second wire slot (210) has a semicircular shape rather than a square shape. The cap member (200) according to another embodiment supports an orthodontic wire (10) having a circular cross-section, and can be utilized to provide a weak orthodontic force to the tooth (T) in the initial stage of orthodontic treatment of the tooth (T). For reference, an identification mark indicating the cross-sectional shape of the second wire slot (210) and / or the inclination of the second wire slot (210) may be formed in a manner such as embossing on the 2-2 surface (200-2) of the cap member (200).

[0514] Drawing 70 shows a side view of a cap member according to another embodiment of the present invention.

[0515] Through the side view, it can be confirmed in more detail that the second wire slot (210) of the cap member (200) of another embodiment is manufactured in a semicircular shape, unlike the second wire slot (210) of the cap member (200) of other embodiments. The diameter of this second wire slot (210) may be 0.3 to 0.9 millimeters, and a cap member (200) having a second wire slot (210) that is 0.8 to 1.2 millimeters larger than the diameter of the orthodontic wire (10) having a circular cross-section used may be selected and used. By using the cap member (200) having the second wire slot (210) of this size, the present invention can reduce the frictional force with the orthodontic wire (10) and fully transmit the orthodontic force provided by the orthodontic wire (10) to the teeth (T).

[0516] Drawing 71 shows a side view of another embodiment of the orthodontic bracket of the present invention, in which a base member and a cap member are combined.

[0517] In another embodiment of the present invention, the force provided by the orthodontic wire (10) is transmitted to the teeth (T) through the wire slot (WS) formed by the second wire slot (210) of the cap member (200) and the first wire slot (110) of the base member (100). In order to effectively provide this orthodontic force, the first wire slot (110) of the base member (100) may be formed so that the width value (Y1) has a value greater than the width value (Y2) of the second wire slot (210) of the cap member (200), and may be manufactured so that a curved surface is formed in the width direction. In addition, the depth value (Z2) of the second wire slot (210) of the cap member (200) may be formed so that the depth value (Z1) of the first wire slot (110) of the base member (100) has a value greater than the depth value (Z1) of the first wire slot (110) of the base member (100). Through this structure, the first wire slot (110) of the base member (100) can stably support the orthodontic wire (10) while internally accommodating the slot protrusions (211) formed on both sides of the second wire slot (210). For reference, the first-first protrusion (193) formed on the first-third surface of the base member (100) used for hanging a rubber band or the first-second protrusion (194) formed on the first-fourth surface can be formed to have a first inclination (D2) of about 15 degrees with respect to an imaginary surface covering the first-second surface (100-2) of the base member (100).

[0518] Drawing 72 shows another embodiment of the orthodontic bracket of the present invention, in which an orthodontic wire is placed between a base member and a cap member.

[0519] When the orthodontic wire (10) is placed over the first wire slot (110) of the base member (100) and the cap member (200) is pressed while moving thereon, the cap member (200) and the base member (100) are fastened in a snap-fit ​​manner, and the orthodontic force provided by the orthodontic wire (10) is transmitted to the tooth (T) through the wire slot (WS) formed by the first wire slot (110) and the second wire slot (210). Looking at this process in more detail, the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) are pressed by the base member (100) and slightly move inward of the cap member (200), and then move outward when they meet the open areas of the 1-1 base fastening member (180) and the 1-2 base fastening member (190), respectively, thereby completing the snap-fit ​​fastening.

[0520] The process of releasing and removing the cap member (200) from the base member (100) can be performed in the opposite direction to the joining process. The 2-1 cap fastening member (220) and the 2-2 cap fastening member (230) of the cap member (200) are moved inward of the cap member (200), and then the cap member (200) is lifted in the direction in which the 2-2 surface (200-2) faces, thereby releasing the joining between the cap member (200) and the base member (100). This process can also be performed using a separate tool that can easily press the 2-1 cap fastening member (220) and the 2-2 cap fastening member (230). In this way, the present invention can easily provide a bracket having an appropriate slot corresponding to the size and shape of the orthodontic wire (10) used in each step of orthodontic treatment, since the joining and releasing between the cap member (200) and the base member (100) can be performed very easily.

[0521] Drawing 73 is a drawing showing the overall appearance of another embodiment of the orthodontic bracket of the present invention.

[0522] Another embodiment of the orthodontic bracket (1000) of the present invention has a difference from the orthodontic bracket (1000) of the previously described embodiment in that the cap member (200) and the base member (100) are connected to each other in a hinge manner (HG). That is, in the case of the other embodiments described above, the cap member (200) and the base member (100) are configured separately and independently, but in the case of the other embodiments, the cap member (200) is connected to the base member (100) in a hinge manner (HG), which is unique in that it is rotatable. These other embodiments can be mainly used on teeth after the premolars rather than on anterior teeth, and together with the orthodontic wire (10) having a circular cross-section that is used together, it effectively supports the gliding movement of teeth after the premolars.

[0523] Drawing 74 is a drawing showing another aspect of the orthodontic bracket of the present invention.

[0524] The orthodontic bracket (1000) according to another embodiment can be viewed in more detail through a side view, and it can be seen that the upper cap member (200) and the lower base member (100) are connected to each other in a hinge manner. In addition, the shape of the wire slot (WS) formed through the combination of the second wire slot (210) of the cap member (200) and the first wire slot (110) of the base member (100) can also be seen. In the case of the drawing, it can be seen that the second wire slot (210) is formed in a semicircular shape in order to support the orthodontic bracket (1000) having a circular cross-section. In detail, it can be seen that the width value of the first wire slot (110) is greater than the width value of the second wire slot (210), and the curvature value of the curved surface of the first wire slot (110) is less than the curvature value of the curved surface of the second wire slot (210), so that it can be seen that it is formed to form a gentle curved surface. For reference, other embodiments of the present invention are mainly used for premolars and molars, and the second wire slot (210) is generally manufactured in a semicircular shape, but is not limited to being formed to have a square cross-section if necessary.

[0525] Drawing 75 is a drawing showing another embodiment of the orthodontic bracket of the present invention, in which the cap member is open.

[0526] As previously described, the cap member (200) of the orthodontic bracket (1000) according to another embodiment of the present invention is rotatable around an axis that operates in a hinge manner (HG). That is, when fastening and combining the base member (100) and the cap member (200), the cap member (200) is pressed while being rotated toward the base member (100), so that the 2-1 cap fastening member (220) moves slightly inward of the cap member (200) and then returns to its original position, thereby forming a snap-fit ​​fastening with the 1-1 base fastening member (180). Conversely, when releasing the base member (100) and the cap member (200), the 2-1 cap fastening member (220) is lifted by rotating its end in a state where it is moved inward of the cap member (200) by a separate tool, etc., so that the fastening between the base member (100) and the cap member (200) is released. In this way, the present invention can further improve user convenience related to orthodontic work on premolars and molars.

[0527] Drawing 76 is a drawing showing the overall appearance of a base member constituting another embodiment of the orthodontic bracket of the present invention, Drawing 77 is a drawing showing the appearance of the first and second surfaces of the base member of another embodiment, Drawing 78 is a drawing showing a side view of a base member according to another embodiment, and Drawing 79 is a drawing showing the first and fourth surfaces of the base member according to another embodiment.

[0528] In another embodiment, the base member (100) may have a pair of hinge protrusions (199) formed on one side of the first wire slot (110) to support hinge-type coupling with the cap member (200), and a 1-1 base fastening member (180) formed on the other side of the first wire slot (110) to support snap-fit ​​coupling with the 2-1 cap fastening member (220) of the cap member (200). That is, similar to the base member (100) of another embodiment described above, the 1-1 base fastening member (180) is formed to open to the outside starting from the 1-2 side (100-2) and penetrating the 1-3 side, but on the opposite side, a pair of hinge protrusions (199) is formed instead of the 1-2 base fastening member (190). For reference, the first wire slot (110) of the base member (100) and the second wire slot (210) of the cap member (200) can be formed to have the same length value.

[0529] Drawing 80 is a drawing showing the overall appearance of a cap member according to another embodiment, Drawing 81 is a drawing showing a side view of a cap member according to another embodiment, Drawing 82 is a drawing showing a portion where a hinge groove is formed of a cap member according to another embodiment, Drawing 83 is a drawing showing a top view of a cap member according to another embodiment, and Drawing 84 is a drawing showing a top view of a cap member according to another embodiment.

[0530] The cap member (200) coupled with the base member (100) of these other embodiments may also have a pair of hinge grooves (291) for hinge coupling, and the hinge protrusions (199) of the base member (100) may be inserted into these hinge grooves (291), thereby connecting the cap member (200) and the base member (100) as one, thereby completing the orthodontic bracket (1000) according to other embodiments of the present invention. In addition, the cap member (200) of these other embodiments may have a cap groove portion (292) formed to prevent the first and second protrusions (194) of the base member (100) and the cap member (200) from colliding with each other when opening and closing about the hinge axis. This part can prevent the cap member (200) from being restricted by the first and second protrusions (194) during the opening process by receiving the first and second protrusions (194) of the base member (100) inside when the cap member (200) is opened. Through this configuration, the orthodontic bracket (1000) according to another embodiment of the present invention can easily support the sliding movement of premolars and / or molars during the orthodontic process.

[0531] As described above, although the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
