Description

Digital bracket for orthodontics {orthodontic digital bracket}

The present invention relates to a digital bracket for orthodontic treatment, and more specifically, to a digital bracket for orthodontic treatment with improved surgical convenience and precision for orthodontic treatment.

In general, occlusion refers to the state in which the upper and lower teeth engage with each other when the mouth is closed. And, malocclusion refers to an incorrect occlusal relationship that causes functional and aesthetic problems due to the alignment of the teeth being out of alignment or the engagement state of the upper and lower jaw being out of the normal position due to some cause.

Here, the cause of malocclusion is known to be largely genetically influenced, but it can also occur due to various causes such as problems with the shape or size of teeth, environmental influences, bad habits, incorrect posture, and congenital disorders.

On the other hand, when malocclusion occurs, the teeth are not aligned, so it is easy for food residue to remain between the teeth. In addition, because it is not easy to keep teeth clean by brushing correctly, plaque increases in the oral cavity, which can easily lead to gum diseases such as dental caries and gum inflammation. Furthermore, if there are teeth that deviate significantly from normal alignment or the jaw is in an abnormal position, there is a high possibility that damage to the teeth, such as tooth fracture, will occur when an external impact is applied.

Accordingly, orthodontic treatment is performed to treat the malocclusion. Here, the orthodontic treatment utilizes the property of teeth to move when subjected to external force.

In detail, orthodontic treatment uses various devices and methods depending on the cause or treatment period. For example, it can be classified into devices that suppress or promote the development of the upper and lower jaw bones or devices that gradually move teeth to a desired position. In addition, it can be divided into a removable device that can be installed and detached in the oral cavity and a fixed device that is attached to the teeth and removed at the end of treatment.

Meanwhile, the most widely used treatment currently is a fixed treatment using a device called a bracket. Fixed treatment using the bracket attaches the bracket to the teeth and moves the teeth using the tension of a wire such as an orthodontic wire or rubber band, and is commonly used in various types of orthodontic treatment.

In detail, the brackets are each firmly attached to the surface of the teeth to be corrected, and the wires are fixed to interconnect the brackets. In addition, by adjusting the tension applied to the wire, the direction and magnitude of the force applied to the wire can be variously adjusted, thereby gradually moving the tooth to be corrected. Accordingly, the position and posture of the tooth to be corrected is changed by the tension of the wire, and orthodontic treatment is performed while the tooth moves little by little.

However, as conventional orthodontic treatment is performed based on the operator's experience, the operator himself is fine-tuned by repeating the process of directly pulling or releasing the wire bound to the patient's teeth without exact certainty. This has the problem of increasing the procedure time and increasing the discomfort and pain of the recipient as it is adjusted to the desired dental structure through repeated trial and error.

In addition, conventional orthodontic treatment is not objective because it relies heavily on the operator's capabilities, and because the recipient must rely entirely on the operator's experience and abilities, it is difficult to achieve a universally desirable state of teeth.

Moreover, the operator's experience and knowledge are qualitative data that are difficult to record as specific data, and vary depending on the individual operator's abilities and experience. Because of this, the desirable orthodontic model itself, which is the final goal of orthodontic treatment, was formed by the subjective viewpoint or experience of the practitioner performing the procedure, so there was a problem in that orthodontic treatment was not universal and objective.

Meanwhile, the bracket is attached to the lingual or labial surface of the tooth to be corrected through an adhesive, and after the bracket is attached and fixed to the tooth, the wire is ligated. At this time, a slit through which the wire is inserted is opened in the bracket. Then, the wire is inserted and fastened into the slits formed in the plurality of brackets.

Here, the slit is provided with a passage through which the wire is introduced and an inner end into which the wire is inserted and fixed, and the passage opens to a narrower width than the inner end. At this time, while the inner end of the slit is formed as a relatively large internal space, the thickness of the body portion where the inner end is formed is formed to be thin.

Because of this, there was a problem in that the bracket was fractured as the tension of the wire was applied to the bracket, especially the outer surface of the bracket. Accordingly, some attempted to solve the fracture problem by increasing the thickness of the bracket. However, when the bracket is manufactured thickly, there is a problem in that the foreign body sensation increases when attached to the tooth, increasing the patient's discomfort. In addition, there was a problem in which the bracket attached to the tooth became separated due to repeated contact or interference with the opposing tooth or tongue.

Furthermore, when the slit through which the wire is fastened to the bracket is opened corresponding to the direction in which the jig is connected, the thickness of the bracket must be made thicker in consideration of the opening direction of the slit. As a result, there was a problem in that the bracket protruded excessively, increasing the patient's discomfort due to the foreign body sensation.

In order to solve the above problems, the present invention aims to provide a digital bracket for orthodontic treatment with improved convenience and precision for orthodontic treatment.

In order to solve the above problem, the present invention has an inner surface molded and attached to either the lingual or labial surface of the tooth to be corrected, and a wire that provides tension is inserted into the body portion that protrudes outward from the inner surface to a predetermined thickness. An attachment pad portion formed with at least one fastening groove that penetrates as much as possible on both sides and opens outward; A first reinforcing rib extending from the center of the outer surface of the attachment pad portion to the other end to reinforce the strength of the outer surface of the attachment pad portion against the tension of the wire, and extending from one end of the first reinforcing rib to both ends of one side of the attachment pad portion. a reinforcing protrusion that includes a second reinforcing rib that is obliquely branched and extends, and is integrally formed to protrude into a predetermined cross-sectional shape smaller than the cross-sectional area of the outer surface of the attachment pad portion; And an alignment portion that protrudes to one side of the attachment pad portion so that the attachment pad portion is disposed at a preset correction position on one surface of the tooth to be aligned, and has a fitting groove formed on the inner surface to surround and fit an end of the tooth to be aligned, A pair of extensions that connect the attachment pad portion and the alignment portion, but are biased toward each outer surface of the attachment pad portion and the alignment portion so that an escape space is formed on the inner side, and extend through a communication hole communicating with the escape space at the central portion in the width direction. A digital bracket for orthodontics is provided, which includes a guide jig portion including a connecting portion provided immediately, and each of the extension bars is integrally connected to a position corresponding to each end of the second reinforcing rib.

Here, a ligation groove is formed concavely on the other end of the attachment pad section, into which an elastic band that wraps and secures the outer surface of the attachment pad section to press and restrain the exposed ends of the wire passing through the fastening groove section is caught and restrained. 1. Preferably, the other end of the reinforcing rib protrudes and extends to the other side of the outer edge of the ligation groove.

Meanwhile, the reinforcing protrusion preferably has a rounded cross-sectional shape on the outer edge so that the cross-sectional area decreases as it goes outward, and an expanded opening recessed to face each other is formed in the central portion of the opening side of the fastening groove.

Through the above solutions, the present invention provides the following effects.

First, as the strength is reinforced through the reinforcing protrusion that protrudes in a 'Y' shape on the outer surface of the attachment pad, even if it is manufactured with a thinner thickness than a conventional bracket, the tension of the wire is applied to the outer surface of the attachment pad during the correction period, causing fastening. Since the fracture rate at the end of the groove is reduced, a compact yet highly durable bracket can be provided.

Second, each reinforcing rib branched in three directions protrudes in the shape of a thin bar, and its outer surface is formed with a rounded curved edge, so the thickness of the outer surface of the bracket gradually becomes thinner toward the outer surface, minimizing foreign body sensation and reducing the period of orthodontic treatment. It can prevent detachment of the bracket due to discomfort and interference with tissues inside the oral cavity.

Third, the connection part connecting the alignment part and the attachment pad part is provided as a pair of extension parts and is continuously connected to each end of the second reinforcing rib that extends obliquely on both sides on the outer surface of the attachment pad part, so that when the alignment part is separated from the bracket, the second reinforcement rib The boundary between the reinforcing rib and the connection part can be segmented, preventing damage to both ends of the attachment pad.

Fourth, the connection part is biased and extended outward at one end of the attachment pad part, securing an escape space spaced apart from the tooth surface on the inside, allowing the attachment pad part to be in close contact with the tooth, and the excess adhesive discharged to the outside of the bracket can be easily removed. The convenience of the procedure can be significantly improved.

Figure 1 is a perspective view of a digital bracket for orthodontics according to an embodiment of the present invention. And, Figures 2a and 2b are front views and usage examples showing a labial bracket among the digital brackets for orthodontics according to an embodiment of the present invention, and Figures 3a and 3b are orthodontic diagrams according to an embodiment of the present invention. This is a front view and example showing a lingual bracket among orthodontic digital brackets. And, Figure 4 is an exemplary view showing the end of a digital bracket for orthodontic treatment according to an embodiment of the present invention, and Figure 5 is a state in which the digital bracket for orthodontic treatment according to an embodiment of the present invention is disposed through the guide jig portion. This is an example diagram showing.

At this time, it is desirable to understand that 'digital bracket for orthodontics' and 'bracket', which will be described below, have the same meaning. In addition, it is desirable to understand that 'tooth' or 'each tooth', which will be described later, has a meaning that substantially corresponds to 'tooth to be corrected' or 'tooth to be corrected'. At this time, it is preferable to understand that the teeth or teeth to be corrected are teeth that require orthodontic treatment using the bracket of the present invention. For example, the teeth to be corrected may be the six anterior teeth where malocclusion mainly occurs.

Referring to Figures 1 to 5, the digital bracket 100 for orthodontics according to the present invention includes an attachment pad portion 110 and a reinforcing protrusion portion 140. At this time, it is desirable to understand that what is indicated as 100A in the drawing is a bracket attached to the labial side, and what is indicated as 100B is a bracket attached to the lingual side.

In detail, the attachment pad portion 110 is preferably formed as a protruding body portion 112 to have a predetermined thickness. The body portion 112 is preferably formed to protrude to the minimum volume in which the fastening groove portion 111, which will be described later, can be formed, and is preferably formed to have an area smaller than the overall area of each tooth to be corrected (t).

In addition, the body portion 112 is not greatly limited in its shape, but in particular, in the case of the lingual bracket 100B, the end corresponding to the root side of the tooth t may be formed to be narrow. That is, the body portion 112 is disposed so that one end faces the occlusal surface of the tooth to be corrected (t), and as the other end faces the root of the tooth to be corrected (t), both sides of the body portion 112 It may be formed in a trapezoidal shape with a narrowing width.

It is preferable that an attachment surface (110a) is formed on the inner surface of the body portion (112) to be attached to either the lingual or labial surface of the tooth (t) to be corrected. Hereinafter, it is preferable to understand that the attachment surface 110a formed on the inner surface of the attachment pad portion 110 and the attachment surface 110a formed on the inner surface of the body portion 112 have the same meaning. In other words, it is preferable to understand that the attachment pad portion 110 is an orthodontic member in which the attachment surface 110a and the fastening groove portion 111 are formed on the body portion 112.

In addition, it is preferable that at least one fastening groove 111 is formed in the body 112. The fastening groove portion 111 is a portion where the wire 113 that provides tension to correct the alignment by moving the position and direction of the tooth to be corrected (t) is inserted, and can be formed as a pair spaced apart as shown in the drawing. there is. At this time, the fastening groove 111 has an inner end 111d that penetrates both sides of the body 112, and has an opening in a preset direction so that the inner end 111d communicates with the outside of the body 112. It is preferable that (111e) is formed.

Here, the opening direction of the opening 111e may be set to correspond to the direction in which the wire 113 is fastened so that the tension of the wire 113 is transmitted, and the opening direction setting of the opening 111e is determined by the present applicant. Since it is disclosed in Patent No. 10-1917274 applied for and registered by , detailed description is omitted. For example, as shown in FIG. 2B, the opening 111e may be formed at one end and the outside of the body 112, and as shown in FIG. 4B, the opening 111e may be formed at one end of the body 112. And an opening may be formed on the other end side.

Additionally, the opening 111e is preferably formed to be narrower than the inner diameter of the inner end 111d. Therefore, when the wire 113 is introduced into the inner end 111d through the opening 111e, it may be caught on a step edge between the opening 111e and the inner end 111d. Through this, the tension of the wire 113 can be stably transmitted to the attachment pad portion 110 while preventing the wire 113 from being separated from the inner end portion 111d.

The reinforcing protrusion 140 is preferably formed to protrude integrally from the outer surface of the attachment pad 110 in the outward direction. Here, the reinforcing protrusion 140 is preferably formed to have a predetermined cross-sectional shape smaller than the cross-sectional area of the outer surface of the attachment pad portion 110. More preferably, the reinforcing protrusion 140 is formed to extend from the central portion of the outer surface of the attachment pad portion 110 by branching in three predetermined directions. That is, the reinforcing protrusion 140 may protrude integrally with a predetermined thickness outward from the outer surface of the attachment pad portion 110 corresponding to the outer side of the fastening groove portion 111.

In detail, the reinforcing protrusion 140 preferably includes the first reinforcing rib 141 and the second reinforcing rib 142.

The first reinforcing rib 141 extends and protrudes from the central portion of the outer surface of the attachment pad 110 toward the other end, and is located on the outside of the fastening groove formed on the other end of the attachment pad 110 (hereinafter referred to as the other fastening groove). It is provided with a protrusion for reinforcement. Preferably, the second reinforcing rib 142 is obliquely branched and protrudes from one end of the first reinforcing rib 141 to both ends of the attachment pad portion 110. The second reinforcing rib 142 is provided to reinforce the outside of the fastening groove (hereinafter referred to as one-side fastening groove) formed on one end of the attachment pad portion 110.

That is, the reinforcing protrusion 140 may be provided by extending the first reinforcing rib 141 and the second reinforcing rib 142 in a 'Y' shape. Therefore, as shown in FIG. 2A or FIG. 4A, when the attachment pad portion 110 is viewed from the outside, the pair of second reinforcing ribs 142 branched from the central portion of the body portion 112 substantially form the body portion. It may be provided in a form extending entirely along the horizontal direction of (112). In addition, the first reinforcing rib 141 and the second reinforcing rib 142 branched from the central portion of the body portion 112 are substantially extended along the longitudinal direction of the body portion 112. It can be.

In particular, the reinforcing protrusion 140 can solve the problem of the outer surface of the attachment pad 110 being fractured due to the tension of the wire 113 being applied in the outer direction of the fastening groove 111. . Therefore, when the bracket 100 is attached to the lingual side of the tooth, the outer structure of the fastening groove 111 is prevented from being damaged due to the pulling force of the wire 113 through the reinforcing protrusion 140. can do.

At this time, the first reinforcing rib 141 is preferably extended and protruded to intersect the penetrating direction of the other fastening groove portion 111b. Accordingly, the outside of the other end of the body portion 112 divided by the opening 111e can be reinforced through the first reinforcing rib 141. In addition, the second reinforcing rib 142 preferably extends and protrudes to intersect the penetrating direction of the one fastening groove portion 111a. Accordingly, since the outer end of the body portion 112 divided by the opening 111e is reinforced through the second reinforcing rib 142, durability against tension of the wire 113 can be significantly improved. At this time, the fact that the first reinforcing rib 141 and the second reinforcing rib 142 extend and protrude to intersect means that the first reinforcing rib 141 and the second reinforcing rib 142 correspond to the penetrating direction of the fastening groove 111. 2. It is preferable to understand that the reinforcing ribs 142 are arranged vertically or obliquely.

In this way, according to the present invention, even if the strength decreases due to the thickness of the body part 112 being thinned by forming the fastening groove part 111, the reduced strength can be compensated for through the reinforcing protrusion part 140. Therefore, in the bracket 100 of the present invention, even if the body portion 112 is formed to be thinner than the existing bracket 100, the body portion 112, especially the fastening groove portion ( 111), the end-side fracture rate can be significantly reduced.

For example, while conventional brackets are formed with a maximum thickness of about 4 mm, the present invention can implement a compact structure with an average thickness of 2.5 mm by applying the reinforcing protrusion 140. Moreover, as the overall area of the attachment pad portion 110 is substantially reinforced through the reinforcing protrusion 140, the area of the bracket 100 can also be reduced. Through this, it is possible to provide a bracket 100 with excellent durability that can support the tension of the wire 113 while minimizing foreign body sensation when the bracket 100 is attached to the tooth t.

In addition, the reinforcing protrusion 140 is provided such that the first reinforcing rib 141 and the second reinforcing rib 142 are formed in a 'Y' shape and protrude in a narrow bar structure. At this time, it is desirable that the cross-sectional shape of the outer edge of each reinforcing rib is formed to be round. Here, it is preferable to understand that each of the reinforcing ribs is the first reinforcing rib 141 and the second reinforcing rib 142.

In detail, the reinforcing protrusion 140 is formed with a curved edge 143 that is rounded along the outer edge, and the cross-sectional area of the reinforcing protrusion 140 may become smaller as it goes outward. Accordingly, the bracket 100 may be formed in a shape whose thickness gradually becomes thinner from the central portion of the outer surface of the body portion 112 to both sides of the other end. Through this, the feeling of a foreign body can be minimized while the bracket 100 is attached to the tooth to be corrected (t), and separation from the tooth (t) due to interference with internal oral tissues such as the tongue can be prevented. there is.

At this time, since the first reinforcing rib 141 is formed in a direction corresponding to the root side of the tooth t, it is preferable to be formed as a single protruding structure corresponding to the longitudinal direction of the bracket 100. Accordingly, the structure of the other end of the bracket 100 may be formed to be narrow in response to the surface shape of the tooth (t), whose cross-sectional area becomes narrower toward the tooth root. Through this, the feeling of foreign matter can be further reduced even if the reinforcing protrusion 140 protrudes outward when attaching the bracket 100.

Of course, in some cases, the reinforcing protrusion may protrude integrally with the outer surface of the attachment pad portion 110 in a shape where reinforcing ribs intersect each other, corresponding to an 'X' shape. Alternatively, the reinforcing protrusion may be an 'I' shaped reinforcing rib extending in correspondence with the longitudinal direction of the attachment pad portion 110 and integrally protruding across the central portion in the longitudinal direction of the attachment pad portion 110. Moreover, the reinforcing protrusion is provided with a pair of 'I'-shaped reinforcing ribs and may protrude integrally along both ends of the attachment pad portion 110 in the longitudinal direction. At this time, when the reinforcing protrusion is formed in an 'I' shape, the widths on both sides may be adjusted at a predetermined interval. In this way, if the reinforcing protrusion 140 is formed with an area smaller than the cross-sectional area of the outer surface of the attachment pad portion 110 and has a structure that protrudes to intersect the penetrating direction of the fastening groove portion 111, it falls within the scope of the present invention.

Meanwhile, the bracket 100 preferably further includes a guide jig portion 120. That is, the bracket 100 of the present invention preferably includes the attachment pad portion 110, the reinforcing protrusion portion 140, and the guide jig portion 120.

In detail, it is preferable that the guide jig part 120 protrudes from one side of the attachment pad part 110. This guide jig part 120 is preferably understood as a part that guides the attachment pad part 110 to be placed at a preset correction position on one surface of the tooth to be corrected (t).

In detail, the guide jig part 120 preferably includes an alignment part 121 and a connection part 122.

The alignment portion 121 has a molding groove 121a formed on the inner surface surrounding the end (ta) of the tooth to be aligned, and is preferably formed at a predetermined distance from one end of the attachment pad portion 110. do. At this time, it is preferable to understand that the end (ta) of the tooth to be corrected is the occlusal surface. That is, the alignment portion 121 may be formed with the outline of the matching groove 121a corresponding to the characteristic protruding structure of the end (ta) of each tooth.

Additionally, the connecting portion 122 is preferably extended to connect the alignment portion 121 and the attachment pad portion 110. In detail, it is preferable that one end of the connecting portion 122 is integrally connected to the alignment portion 121 and the other end is integrally connected to one end of the attachment pad portion 110. At this time, the connecting portion 122 is preferably extended toward the outer surfaces of the attachment pad portion 110 and the alignment portion 121 in a biased manner.

That is, in the bracket 100, the alignment part 121 and the attachment pad part 110, which are spaced apart at a predetermined interval, may be connected through the connection part 122. At this time, as the connecting portion 122 is biased toward the outer surface of the alignment portion 121 and the attachment pad portion 110, an escape space 126 may be formed on the inner surface. Accordingly, the entire outer inner surface of the attachment pad portion 110 may be exposed to the outside. Through this, an escape space 126 for excess adhesive among the adhesive applied between the attachment pad portion 110 and the tooth (t) in order to attach the attachment pad portion 110 may be formed. The excess adhesive is preferably understood as adhesive that is discharged to the outside of the attachment pad portion 110 while attaching the attachment pad portion 110 to the surface of the tooth (t).

In detail, as the adhesive is applied to the attachment surface 110a or the surface of the tooth t and then pressed, the excess adhesive excluding the amount of adhesive required to attach the bracket 100 is removed from the bracket 100. It is pushed outward from the inner side and discharged. At this time, the excess adhesive may be pushed and discharged through the escape space 126 to one end of the bracket 100 where the guide jig portion 120 is formed.

Therefore, the attachment surface 110a can be closely attached to the surface of the tooth t. In addition, since the thickness of the adhesive layer formed by curing the adhesive is minimal, the bracket 100 can be compactly attached to the surface of the tooth t. Moreover, since the excess adhesive discharged into the escape space 126 can be easily removed by scratching or wiping with a dental instrument such as tweezers, the convenience of the procedure can be significantly improved.

At this time, it is more preferable that the connecting portion 122 extends from one end of the body portion 112 with a pair of extension bars 123a and 123b spaced apart on both sides. Accordingly, a communication hole 124 penetrating inward and outward may be formed between the pair of extension bars 123a and 123b. Here, the communication hole portion 124 is preferably in communication with the escape space 126. That is, the escape space 126 may be opened on both sides between the alignment portion 121 and the attachment pad portion 110 and may also be opened outward through the communication hole portion 124.

Therefore, the excess adhesive can be easily removed through the communication hole 124. Through this, the attachment surface 110a can be closely attached to one surface of the tooth t regardless of the amount of excess adhesive discharged to one end of the attachment pad portion 110. In addition, since the excess adhesive remaining on the inner surface of the connecting portion 122 is substantially minimized, the problem of the connecting portion 122 being attached to one surface of the tooth t due to the adhesive can be fundamentally solved. . Through this, the guide jig part 120 can be easily removed from the end (ta) of the tooth to be corrected after the attachment of the attachment pad part 110 is completed.

Through this, the bracket 100 according to the present invention secures sufficient space for the excess adhesive to be discharged regardless of the amount of adhesive applied through the communication hole 124 in communication with the escape space 126. You can. In addition, since the extension bars 123a and 123b are provided as a pair and spaced apart on both sides of one end of the attachment pad portion 110, the attachment position of the attachment pad portion 110 guided through the alignment portion 121 can be accurately aligned and supported.

Moreover, since the pair of extension bars 123a and 123b support both ends of the attachment pad portion 110, the attachment position of the attachment pad portion 110 can be stably guided even if it is formed to be thin. Therefore, since the alignment part 121 and the central part of the attachment pad part 110 are connected by a single thin connecting means, the problem of positional error such as tilting of the position of the bracket when an external force is applied can be fundamentally solved. .

At this time, the connection portion 122 is biased to the outside of one end of the attachment pad portion 110 and is spaced apart. Therefore, even if the cutting device is inserted through the communication hole 124 or broken and separated by bending while holding the grip protrusion 130, the end of the cutting device or the fractured end of the extension bar 123 is not connected to the tooth. It is possible to prevent contact with one surface of (t). Through this, it is possible to prevent the surface of one side of the tooth t from being damaged by being scratched by the cutting tool or the end of the extension bar 123.

Here, the connection portion 122 may be formed to extend the pair of extension bars 123a and 123b corresponding to a preset cross-sectional area or diameter. That is, the connection part 122 can be uniformly formed with a constant thickness regardless of the thickness of the attachment pad part 110 and the alignment part 121. At this time, the pair of extension bars 123a and 123b may be formed to a thickness that allows them to be easily segmented to separate from the attachment pad portion 110 when the operator bends them with force. Therefore, excessive force is not required when cutting or dividing the connection portion 122 from one end of the attachment pad portion 110, and the force applied when separating the connection portion 122 causes the attachment pad portion 110 It is possible to prevent the attachment location from being changed unnecessarily.

At this time, a gap maintenance portion 123c may be further formed to support the gap between the pair of extension bars 123a and 123b. In detail, the gap maintenance portion 123c is disposed across the communication hole portion 124, and both ends may be integrally connected to the pair of extension bars 123a and 123b. At this time, the extension length of the gap maintenance part 123c may correspond to the inner gap between the pair of extension bars 123a and 123b.

Accordingly, deformation, such as widening or twisting of the gap between the pair of extension bars 123a and 123b, can be prevented through the gap maintenance part 123c, and the deformation of the extension bars 123a and 123b can cause the deformation of the extension bars 123a and 123b. The problem of changing the position of the attachment pad portion 110 can be fundamentally solved. Therefore, in the process of attaching the bracket 100 to the tooth to be corrected (t), the position where the alignment part 121 and the attachment pad part 110 are connected through the connecting part 122 can be firmly maintained. there is.

In this way, according to the present invention, even if the alignment part 121 and the attachment pad part 110 are spaced apart by a predetermined distance, the attachment pad part 110 can be guided to the correct attachment position through the connection part 122. Through this, the tension of the wire 113 can be accurately transmitted to the bracket 100, and the tooth to be corrected (t) can be precisely corrected and moved according to a preset orthodontic plan.

Here, the pair of extension bars 123a and 123b are preferably connected to positions corresponding to each end of the second reinforcement rib 142. Moreover, it is preferable that each of the extension bars 123a and 123b is continuously and integrally connected to each end of the second reinforcing rib 142. Accordingly, each of the extension bars 123a and 123b can be spaced apart from one surface of the tooth t by substantially the thickness of the attachment pad portion 110, and the escape space 126 can be formed larger. there is. Through this, it is easier to remove the excess adhesive, and the excess adhesive can be further prevented from adhering to the inside of the connecting portion 122 and the fitting groove 121a.

In addition, since the pair of extension bars 123a and 123b extend from each end of the second reinforcement rib 142, when the guide jig part 120 is separated through a process described later, the attachment pad part 110 It is possible to prevent one end from being segmented together with the pair of extension bars 123a and 123b. Accordingly, since the thickness of one end of the attachment pad portion 110 is maintained constant, the tension of the wire is stably supported, and the fracture rate can be further reduced.

Furthermore, in the design process of the bracket 100, the design of the reinforcing protrusion 140 and the guide jig portion 120 can be simplified, thereby significantly improving manufacturing convenience. The design process of this bracket 100 will be described later.

Meanwhile, the fitting groove (121a) is preferably formed to correspond to a tooth contour that is substantially continuous with the attachment surface (110a). In addition, the bracket 100 may be designed based on a scanning image obtained for the oral cavity so that the fitting groove 121a and the attachment surface 110a correspond to a continuous tooth contour.

In detail, an oral scan image of the target dental arch including the tooth to be corrected (t) is acquired, and each tooth image included in the acquired oral scan image can be virtually adjusted to correspond to a preset continuous dentition structure. Here, the preset continuous dentition structure is preferably understood as a virtual dentition line according to an orthodontic treatment plan established to correct the dentition of the patient to a desirable functional and aesthetic occlusion state. At this time, the oral scan image can be loaded into the planning unit, which is a simulation device that can virtually control the video or image.

And, the virtual design image of the bracket can be selected and extracted from the digital library. At this time, the digital library is preferably understood as a storage unit in which external shape information on components required for orthodontic treatment is stored as three-dimensional vector data. The digital library may be included in the planning unit or may be connected to the planning unit through wired or wireless communication.

In detail, the oral scan image is loaded into the planning unit and virtually adjusted to correspond to the continuous dentition structure. And, the virtual design image of the bracket selected and extracted from the digital library may be loaded into the planning unit. Here, the virtual design image may include a virtual pad portion, a virtual alignment portion, and a virtual connection portion.

Here, it is desirable to understand that the virtual pad part is three-dimensional basic design information of the attachment pad part 110. The virtual pad portion may be set as three-dimensional vector data for a block shape corresponding to the outer shape of the body portion 112. When placed on each tooth image of the oral scan image, this virtual pad unit may be set to a volume that can overlap with each tooth image. In addition, it is desirable to understand that the virtual alignment unit is three-dimensional basic design information of the alignment unit 121. The virtual alignment unit may be set to three-dimensional vector data about the block shape corresponding to the external shape of the alignment unit 121. This virtual alignment unit may be placed overlapping the top of each tooth image, that is, the image corresponding to the occlusal surface side.

In addition, it is desirable to understand that the virtual connection part is three-dimensional basic design information of the connection part 122. The virtual connection part may be set as three-dimensional vector data corresponding to the external shape of the connection part 122 and the reinforcing protrusion 140. That is, the virtual connection part may be continuously connected to the 'Y'-shaped virtual reinforcement part corresponding to the three-dimensional design information of the reinforcement protrusion 140. Additionally, the virtual connection unit may be stored substantially integrated with the virtual pad unit.

At this time, the virtual pad portion may be virtually arranged on one surface of each tooth image that has been virtually adjusted to correspond to the continuous dentition structure, and the virtual alignment portion may be virtually spaced apart from one end of the virtual pad portion. Here, three-dimensional surface information of the attachment surface 110a may be set corresponding to the boundary surface where the virtual pad portion and each tooth image overlap. In addition, three-dimensional surface information of the matching groove 121a can be set corresponding to the boundary surface where the virtual alignment unit and the angle tooth image overlap. In addition, as one end of the virtual connection part and the virtual alignment part are integrated, three-dimensional design information of the bracket 100 in which the virtual pad part and the virtual alignment part are formed integrally can be set.

Here, the virtual pad portion is provided in plural pieces to individually correspond to each tooth t, and can be set and stored through a virtual wire, which is the design information of the wire 113. At this time, the virtual wire is connected to the continuous dentition structure. It can be set to a corresponding arc shape. Additionally, the virtual alignment units may be spaced at predetermined intervals on the upper side of each virtual pad unit and may be set with set template information. Therefore, when one template information extracted from the digital library is loaded into the planning unit, it can be quickly virtual aligned to the oral scan image.

In addition, three-dimensional design information of the fastening groove portion 111 may be set based on the overlapping area of the virtual wire and the virtual pad portion. In detail, three-dimensional design information for the inner end portion 111d may be set corresponding to the overlapping portion of the virtual wire and the virtual pad portion. In addition, the three-dimensional design information for the opening 111e can be set by considering the direction in which the wire 113 can be easily inserted.

This bracket 100 can be formed of a synthetic resin material that is harmless to the human body and easy to print with a 3D printer, and the 3D design information of the bracket 100 is output through a manufacturing device such as a 3D printer to be integrated into one piece. can be manufactured. Therefore, the reinforcing protrusion 140 protruding in a 'Y' shape, the pair of extension bars 123a and 123b formed spaced apart on both sides, and the attachment surface formed corresponding to one surface of the tooth t. The shapes of (110a) and the matching groove (121a) can be manufactured precisely and easily.

Furthermore, the synthetic resin for manufacturing the bracket 100 is preferably provided in a color substantially similar to that of the tooth t. Therefore, even if the bracket 100 is attached to the labial surface of the tooth t, the bracket 100 does not stand out excessively, and aesthetics can be significantly improved. In addition, the synthetic resin may be made of a material having a strength sufficient to support the tension of the wire 113 at a certain level during photocuring.

Meanwhile, it is preferable that the ligation groove 114 is concavely formed on the other end of the attachment pad portion 110.

In detail, when the wire 113 is inserted and fastened into the fastening groove portion 111, the wire 113 is exposed on both sides of the attachment pad portion 110. Additionally, in order to prevent the wire 113 from falling out through the opening 111e, an elastic band 115 may be further provided to secure the wire 113. This elastic band 115 elastically expands to a greater extent than the circumference of the outer surface of the bracket 100 through the elastic force of the material, but expands and contracts when wrapped around the outer surface of the bracket 100 and is firmly pressed and fixed, thereby improving convenience of use and installation. can be significantly improved.

At this time, the wire 113 may be restrained when inserted into the fastening groove 111 through the elastic band 115 elastically fixed to surround the entire outer surface of the bracket 100. Here, as a portion of the elastic band 115 is received and locked in the ligation groove 114, the elastic band 115 can be firmly elastically fixed to the attachment pad portion 110, and the wire ( 113) may remain detained.

Here, the other end 141a of the first reinforcing rib 141 is preferably protruded and extended to the other side of the outer edge of the ligation groove 114. That is, the other end 141a of the first reinforcement rib 141 may protrude further from the edge of the other end of the attachment pad 110 to the other side. Accordingly, since the depression depth of the ligation groove 114 is formed relatively deeper through the other end 141a of the first reinforcement rib 141, the elastic band 115 can be more stably caught and restrained.

Furthermore, the depression depth of the ligation groove 114 can be minimized through a structure in which the other end 141a of the first reinforcing rib 141 protrudes further. Therefore, even if the fastening groove 111 penetrates and opens the attachment pad portion 110, the outer thickness of the body portion 112 can be maintained as thick as possible. Through this, the problem of the body portion 112 being fractured due to tension applied to the wire 113 can be significantly reduced.

In addition, it is preferable that expanded openings 116a and 116b, which are recessed and face each other, are formed at the opening side of the fastening groove 111, that is, at the center of the opening 111e. That is, even if the opening 111e is opened at an interval smaller than the inner end 111d of the fastening groove and the diameter of the wire 113, the facing edge of the opening 111e through the expanded openings 116a and 116b. can be easily elastically deformed. Therefore, excessive force is not required when inserting the wire 113 through the opening 111e, and the convenience of the procedure when fastening the wire 113 can be significantly improved. These expanded openings 116a and 116b may be formed on opposing edges of the opening 111e to have an oval shape. Therefore, when the wire 113 is introduced, elastic deformation is easy and no angled corners are formed, so damage to the wire 113 can be prevented.

Meanwhile, the alignment part 121 may be further provided with the grip protrusion 130.

In detail, the grip protrusion 130 is a configuration that allows the operator to attach the bracket 100 and transport and align it toward the tooth to be corrected (t), and protrudes and extends from the alignment portion 121. The grip protrusion 130 may be provided in a flat plate shape so that one end has a preset mounting area to facilitate the operator's grip. Therefore, even if the operator directly holds the grip protrusion 130 with his or her hand, it is possible to prevent it from coming off the hand through a stable grip.

In addition, the grip protrusion 130 extends in one direction to a predetermined length, so that even if the operator directly attaches the grip protrusion 130 by hand, it contacts the tooth to be corrected (t) and the attachment pad portion 110. It can be prevented from happening. Moreover, a step is formed between the alignment part 121 and the connecting part 122 through the support block 125 provided on one side of the connecting part 122. Accordingly, it is possible to limit the operator's fingertips from contacting the outer surface of the support block 125 and approaching the attachment pad portion 110.

Accordingly, the attachment pad part 110 side can be substantially separated from the guide jig part 120 side. Through this, hygiene can be significantly improved by preventing contamination of the operator's fingertips by contacting the tooth to be corrected (t) or the attachment pad portion 110. In addition, it is possible to prevent the excess adhesive (g) discharged toward the communication hole 124 from sticking to the operator's hands. Accordingly, the operator's discomfort is minimized in the process of attaching the bracket 100 to the tooth t, and thus the convenience of the procedure can be significantly improved.

At this time, a marking portion 131 that displays guidance information about the type and location of each tooth t may be formed at the end of the grip protrusion 130. In detail, the marking portion 131 may include guide information about the tooth t to which each bracket 100 is attached. In this marking unit 131, the unique number of each tooth (t) may be displayed in numbers or Braille. Accordingly, the operator can attach the bracket 100 to the correct position in the oral cavity by visually checking the marking portion 131 or recognizing it through the touch of the fingertip. Moreover, when the marking portion 131 is displayed in a protruding or engraved manner, the convenience of the procedure can be further improved because it simultaneously performs the function of guiding the position of the tooth t and the function of preventing the operator's hand from slipping. there is.

Here, it is preferable that the angle between the grip protrusion 130 and the connection portion 122 is formed to be 180 degrees or less. For example, the angle between the grip protrusion 130 and the connection portion 122 may be formed in the range of 150 to 170 degrees. Therefore, even if a small force is applied to the grip protrusion 130 through the lever principle, the thin extension bars 123a and 123b can be easily segmented with one end of the relatively thick attachment pad portion 110 as a boundary. You can. In addition, the rotation radius of the grip protrusion 130 for separating the guide jig portion 120 is minimized, and the force that can separate the extension bars 123a and 123b without a separate cutting tool is transmitted, thereby improving convenience of the procedure. can be significantly improved.

Meanwhile, the bracket 100 can be attached to the tooth to be corrected (t) through the following process.

First, the operator attaches the grip protrusion 130 and moves the bracket 100 into the patient's oral cavity. Then, the attachment surface 110a and the matching groove 121a are arranged to match each tooth t. At this time, since information about each tooth (t) is displayed on the grip protrusion 130, the operator can accurately place the bracket 100 on the corresponding tooth (t). In addition, since the attachment surface 110a and the matching groove 121a are formed to correspond to the specific curve of each tooth t, they are precisely placed at the exact position of each tooth t according to a preset orthodontic plan. It can be.

At this time, the adhesive may be applied and prepared on the attachment surface 110a or one surface of the tooth t. Therefore, when the attachment pad portion 110 is in close contact with one surface of the tooth (t) so that the bracket 100 is molded to one surface of the tooth (t), the excess adhesive is applied to the attachment pad portion (110). It may be discharged to the outside.

Here, the escape space 126 is formed inside the connection part 122, and the communication hole 124 is also formed in the connection part 122, so that a sufficient space through which the excess adhesive can be discharged can be formed. . Accordingly, the attachment pad portion 110 can be closely attached to one surface of the tooth t.

Here, the excess adhesive discharged to the outer inner surface of the attachment pad portion 110 is removed by scraping or wiping. At this time, the escape space 126 is formed inside the connecting portion 122 that extends deviated outward from one end of the attachment pad portion 110 to facilitate the excess adhesive discharged to one end of the attachment pad portion 110. It can be easily removed. In addition, since the spaced state of the alignment part 121 and the attachment pad part 110 is supported through the connection part 122, the problem of the excess adhesive flowing into the fitting groove 121a is substantially eliminated. It can be. Therefore, when the guide jig part 120 is separated, the alignment part 121 can be quickly separated from the tooth t.

Then, the adhesive laminated between the attachment pad portion 110 and one surface of the tooth t is hardened. Here, the adhesive may be made of a material that hardens through curing light such as ultraviolet rays. Therefore, the adhesive can be cured quickly and the procedure time can be significantly shortened.

On the other hand, when the operator holds the grip protrusion 130 and applies force in the outer direction of the oral cavity, the connecting portion 122 may be bent and separated based on the boundary between the connecting portion 122 and the attachment pad portion 110. there is. At this time, the other end of the connection portion 122 may be separated while being pressed toward the inner side of the attachment pad portion 110 in response to the direction in which the grip protrusion 130 is bent. That is, the pressure transmitted to the attachment pad portion 110 as the grip protrusion 130 is separated will substantially correspond to the direction of the force applied to attach the attachment pad portion 110 to the tooth (t). You can. Accordingly, the problem of the attachment pad portion 110 being separated from the tooth (t) when the guide jig portion 120 is separated can be prevented.

Subsequently, the wire 113 is inserted and fastened through the fastening groove 111, and the elastic band 115 can be fixed so that the wire 113 can be stably fixed.

At this time, terms such as “include,” “comprise,” “equip,” or “have,” as used above, mean that the corresponding component may be present, unless specifically stated to the contrary.
