1 is a perspective view of a transparent calibration device according to an embodiment of the present invention.

Referring to FIG. 1, the transparent orthodontic device includes a transparent cover 100 coupled to a set of teeth on a user's upper and / or lower jaw.

In one embodiment, the transparent cover 100 may cover the lower or upper jaw teeth of the user. Hereinafter, a case in which the transparent cover 100 is applied to the lower jaw tooth for convenience of description. However, the present invention is not limited thereto, and the description of the lower jaw teeth may be replaced with the description of the upper jaw teeth.

With reference to FIG. 2, some terms used herein will be defined.

2 is a schematic diagram illustrating a transparent calibration apparatus according to an embodiment of the present invention.

As shown in FIG. 2, a tooth may be referred to as follows. That is, sequentially, the first inner incisors 11, the first incisors 12, the first canine 13, the first first small molars 14, the first second small molars 15, and the first first large The molar 16, the first second large molar 17 and the first third large molar 18 can be arranged. Since the left and right teeth are symmetrical, when the second inner tooth 21 is disposed next to the first inner tooth 11, the second side tooth 22 may be disposed in the same order. The upper jaw teeth and the lower jaw teeth correspond to each other, and the names of the upper jaw teeth may also be referred to as the names of the lower jaw teeth.

In one embodiment one tooth may comprise an outer wall, an inner wall and an upper end. The outer wall may mean a side wall visible from the outside of the user's mouth. The outer wall may be a portion facing the inner side of the lips. The inner wall may mean a portion adjacent to the user's tongue. The inner wall may be placed in contact with the tongue according to the user's tongue is placed, or the flow of the tongue.

The upper end is an upper end of the tooth, and may be disposed between the outer wall and the inner wall. That is, the upper end may spatially mean the end of the tooth exposed over the gum.

That is, the upper end may mean a portion in which the upper teeth and the lower teeth contact each other or a portion in which the food is crushed in contact with the food.

The upper ends of the incisors and canines may be narrower than the upper ends of the molar teeth. That is, the upper ends of the incisors and the canine are relatively sharp and suitable for tearing food. In comparison, the upper ends of molar teeth are relatively wide and may be suitable for crushing torn food.

Hereinafter, a transparent calibration apparatus according to some embodiments of the present disclosure will be described.

The transparent cover 100 may cover the upper jaw teeth and / or the lower jaw teeth as a whole. In one embodiment, the transparent cover 100 may cover from the first third large molar to the opposite second third large molar.

In one embodiment, the transparent cover 100 has a shape retaining force, and may be fitted to a user's dentition. That is, since the transparent cover 100 has a property of maintaining a predetermined shape, when the transparent cover 100 is inserted into a user's teeth, the transparent cover 100 may provide an action force, that is, a correction force, necessary for the user's teeth.

That is, the elastic force of the transparent cover 100 may provide orthodontic force to the target tooth, thereby rotating, laying down, or standing the tooth. That is, the transparent cover 100 may induce rotational movement or tilt movement of the target tooth.

The inner side of the transparent cover 100 may have a negative contour shape of the user's teeth so that the user's teeth can be inserted. However, it may have a deformed form based on the negative shape in order to be fitted to the user teeth or to provide an action force necessary for correction. In other words, the sound may reflect the shape of the teeth in the corrected state, rather than the sound shape reflecting the current tooth.

The transparent cover 100 may be light transmissive or semitransparent as a whole. In other words, the transparent cover 100 may be transparent. That is, the transparent cover 100 may transmit light at least partially so that the tooth is visually recognized from the outside. As a result, others cannot easily check whether the user has calibrated at a distance greater than a certain distance. That is, the transparent calibration device according to some embodiments of the present invention is superior in terms of aesthetics compared to the prosthetic device using a wire.

In one embodiment, the transparent cover 100 may be made of a material having elasticity. The elastic or shape holding force of the transparent cover 100 may provide a force in a predetermined direction to the tooth to move the tooth in accordance with the corrective purpose.

In one embodiment, the transparent cover 100 may be made of a transparent resin. The transparent resin may include, for example, one or more selected from the group consisting of polycarbonate, polyethylene terephthalate, polyurethane, and glycon modified polyethylene terephthalate.

In another embodiment, the transparent cover 100 may be made of a polymer material or an elastomer. The polymeric materials or elastomers are, for example, natural polyisoprene, such as cis-1,4-polyisoprene natural rubber and trans-1,4-polyisoprene gut perca, synthetic polyisoprene, polybutadiene, chloroprene rubber, polychloroprene, neoprene, Vaporene, butyl rubber, halogenated butyl rubber, styrene-butadiene rubber, nitrile rubber, halogenated nitrile rubber, ethylene propylene rubber, ethylene propylene diene rubber, epichlorohydrin rubber, polyacryl rubber, silicone rubber, fluorosilicone rubber, fluoro Low elastomers, perfluoroelastomers, polyether block amides, chlorosulfonated polyethylene, ethylene-vinyl acetate, thermoplastic elastomers, polysulfide rubbers, elastomeric olefins or combinations thereof.

The material of the transparent cover 100 listed above is exemplary, but is not limited thereto. That is, a material having physical properties necessary to achieve the function (transparency, elasticity, etc.) of the transparent cover 100 may be used as the material of the transparent cover 100.

The force required for orthodontics can be divided into two types. In other words, the transparent cover 100 formed in consideration of the calibration target is a force that is given as a whole and a force that is individually given to a specific tooth.

The latter can be conveyed in the following manner.

3 is a schematic diagram illustrating a transparent calibration device according to an embodiment of the present invention.

Referring to FIG. 3, the transparent orthodontic device according to the embodiment of the present invention may include an attachment by applying an individual action force to a specific tooth.

In one embodiment, the attachment may be attached on the inner wall and / or outer wall of the user's teeth.

The attachment is a three-dimensional shape, and may be any one of a polyhedron, a three-dimensional figure including a portion of the polyhedron and at least partly a curved surface. Since the direction and the magnitude of the action force may vary depending on the position, size or shape of the attachment, the position, size or shape of the attachment may be different depending on the purpose of calibration.

In addition, the movement pattern of the target tooth may vary according to the position, size, or shape of the attachment. The movement aspect may be, for example, tilt movement, rotation movement, fixed movement or pressure movement.

A depression may be formed in the transparent cover 100 to correspond to the attachment. The depression may have a negative shape of the attachment.

In one embodiment, the depression may be formed by the pressure applied by the transparent cover 100 and the elasticity of the material of the transparent cover. That is, when the transparent cover 100 is tightly fitted on an attachment made of a rigid material, a depression corresponding to the attachment may be formed due to the elasticity of the material. In this case, the direction of the force provided by the transparent cover 100 may vary according to the shape of the attachment.

In one embodiment, the first attachment a1 may be attached to the user's teeth. An adhesive for attachment may be applied between the first attachment a1 and the tooth. In one embodiment, the first attachment a1 may have a circular planar shape. When the first attachment a1 is disposed at the center of the outer wall, the tooth may be pushed inward from the outside and thus the tooth may be inclined.

The first recess 101 may be formed in the transparent cover 100 to correspond to the first attachment a1. The first recess 101 may have a negative shape corresponding to the first attachment a1.

In one embodiment, the second attachment a2 may be an oval having a planar shape biased to one side. In this case, the forces acting on one side and the other side based on the tooth center may be opposite to each other. That is, in the case of the second attachment (a2) may cause a rotational movement of the teeth.

A second recess 102 may be formed in the transparent cover 100 to correspond to the second attachment a2. The second recess 102 may have a negative shape corresponding to the second attachment a2.

In the case of the third attachment a3, the planar shape may be a straight oval. In this case, the degree of protrusion of the top and bottom of the oval attachment may be different. The difference in the shape of the protrusions can be lifted (moving) or pushed down. (High pressure movement)

The third recess 103 may be formed in the transparent cover 100 to correspond to the third attachment a3. The third recess 103 may have a negative shape corresponding to the third attachment a3.

3 illustrates only a few of the various forms of attachments, and the number and shape of attachments is not limited thereto. That is, one or more attachments and various types of attachments can be applied in various ways to provide the corrective force needed for the target tooth.

In order for the transparent orthodontic device to achieve its purpose, it is necessary to wear it for a sufficient time until the actual movement of the tooth appears. (Typically 16-21 hours per day, 7-14 days or more)

However, the transparent orthodontic device is easy to snap in and out, and causes inconveniences while being worn, so it is not easy for the user to be patiently putting on. One of the reasons for feeling the inconvenience is the foreign body caused by the transparent calibration device, reducing the inconvenience that the user may feel somewhat discomfort.

The transparent calibration device according to an embodiment may include an incision OP. The cutout OP cuts the transparent cover 100, thereby exposing a portion of the tooth.

Hereinafter will be described in detail with reference to FIG.

4 is a plan view of a transparent calibration device according to an embodiment of the present invention.

Referring to FIG. 4, the transparent calibration device may include a cutout OP0 for cutting off the transparent cover 100.

In one embodiment, the cutout OP0 may expose the upper end portion 11_t of the first inner incisor 11 and the upper end portion 12_t of the second inner incisor 21.

In general, the foreign body feeling felt by the user is greatest in the sensation felt by the first inner incisors 11 and the second inner incisors 21 and the touch with the tongue.

As shown in FIG. 4, when the cutout OP0 exposes the upper end portion 11_t of the first inner tooth 11 and the upper end portion 12_t of the second inner tooth 21, the first inner tooth 11 and the second inner tooth 21 are exposed. The inner incisors 21 can reduce the feeling of foreign matter.

In addition, the first inner incisor 11, the inner wall 11_i and the second inner side of the first inner incisor 11 in the transparent cover 100 to reduce the feeling of foreign body felt by the tongue contact with the first inner incisor 11 and the second inner incisor 21. The thickness of the portion covering the inner side wall 21_i of the front tooth 21 may increase as the distance from the outer circumference of the cutout OP0 is increased.

In other words, the transparent cover 100 may include a thickness reduction section in which the thickness decreases closer to the outer circumference of the cutout OP0. That is, the thickness of the portion of the transparent cover 100 corresponding to the inner wall 11_i of the first inner incisor 11 and the inner wall 21_i of the second inner incisor 21 is most near the outer periphery of the cutout OP0. It may be thin and thickest at the incision OP0 and at the furthest part (close to the gum). That is, as the distance from the outer circumference of the cutout OP0 increases, the thickness of the transparent cover 100 may gradually increase.

In this case, the user's tongue is the upper end portion 11_t of the first inner tooth 11 exposed from the portion corresponding to the inner wall of the first inner tooth 11 and the second inner tooth 21 in the transparent cover 100. And it is possible to move naturally to the upper end portion 12_t of the second inner tooth 21, thereby reducing the sense of foreign matter.

5 is a plan view of a transparent calibration device according to another embodiment of the present invention.

Referring to FIG. 5, in one embodiment, the cutout OP includes the upper end portion 11_t of the first inner incisor 11 and the upper end portion 21_t of the second inner incisor 21 and the first in the transparent cover 100. At least a portion of the inner wall 11_i of the inner incisor 11 and the inner wall 21_i of the second inner incisor 21 may be exposed.

Specifically, the cutout OP may completely expose the upper end portion 11_t of the first inner incisor 11 and the upper end portion 21_t of the second inner incisor 21 in the transparent cover 100.

In addition, the cutout OP may at least partially expose the inner wall 11_i of the first inner tooth 11 and the inner wall 21_i of the second inner tooth 21.

FIG. 5 illustrates a case where the cutout OP partially exposes the inner wall 11_i of the first inner tooth 11 and the inner wall 21_i of the second inner tooth 21. However, the present invention is not limited thereto, and in other embodiments, the cutout OP may completely expose the inner wall 11_i of the first inner tooth 11 and the inner wall 21_i of the second inner tooth 21. It may be.

As described above, foreign matter may be generated by contact of the tongue and the transparent cover 100. As shown in FIG. 5, the cutout OP includes the upper end portion 11_t of the first inner incisor 11 and the upper end portion 21_t and the first inner incisor of the second inner incisor 21 in the transparent cover 100. When exposing at least a portion of the inner wall 11_i and the inner wall 21_i of the second inner incisor 21 of 11, foreign matters caused by contact of the tongue and the transparent cover 100 may be reduced. Even in that case, since the outer walls of the first inner tooth 11 and the second inner tooth 21 are covered by the transparent cover 100, the corrective force provided by the transparent cover 100 can be maintained. (It may be a little weaker, but you can maintain the amount needed for correction.)

In addition, in another embodiment, in order to further reduce the feeling of foreign body felt by the tongue, the thickness of a portion adjacent to the outer circumference of the cutout OP in the transparent cover 100 may become thicker as it moves away from the outer circumference of the cutout OP. . That is, the transparent cover 100 may include a thickness reduction section in which the thickness decreases as it approaches the outer circumference of the cutout OP.

In other words, the thickness of the portion covering the first side incisor 12 and the second side incisor 22 in the transparent cover 100 is the thinnest in the region adjacent to the outer periphery of the incision OP, and the canines 13 and 23 It may be thickest in the vicinity of and.

That is, the thickness of the portion covering the first side incisor 12 and the second side incisor 22 in the transparent cover 100 may gradually increase as the distance from the cutout OP is increased.

The user's tongue generally contacts the first inner incisor 11, the second inner incisor 21, the first side incisor 12, and the second side incisor 22. As shown in FIG. 5, the transparent cover 100 at least partially exposes the inner walls of the first inner tooth 11 and the second inner tooth 21, and the first and second incisors 12 and 22. When the thickness of the portion covering the gradual increase is increased, the movement of the tongue moving on the first inner incisor 11, the second inner incisor 21, the first incisor incisor 12, and the second incisor incisor 22 is natural. This can reduce the feeling of foreign body feeling on the tongue.

Therefore, detailed description thereof will be omitted.

In addition, the cutout OP2 may expose the upper end portion 12_t of the first side incisor 12 and the upper end portion 22_t of the second side incisor 22. As described above, it is the first inner incisors 11 and the second inner incisors 21 that feel the greatest sense of discomfort. Secondly, it is a first side incisor 12 and a second side incisor 22 that feel a large amount of foreign body. In one embodiment, when the incision OP2 exposes the upper end 12_t of the first side incisor 12 and the upper end 22_t of the second side incisor 22, the first side incisor 12 and the second side The foreigner feeling that the front incisors 22 feel can be reduced.

In addition, the cutout OP2 may expose a portion of the inner wall 12_i of the first side teeth 12 and the inner side wall 22_i of the second side teeth 22. In particular, a portion adjacent to the upper end 12_t of the inner side wall 12_i of the first side incisor 12 and a portion adjacent to the upper side 22_t of the inner side wall 22_i of the second side incisor 22 may be exposed. .

The user's tongue generally contacts the first inner incisor 11, the second inner incisor 21, the first side incisor 12, and the second side incisor 22. In the case of the first incisor 12 and the second incisor 22, in particular, the first incisors 12 and 22_t are frequently in contact with the portions adjacent to the upper ends 12_t and 22_t.

The foreign body feeling caused by contact of the inner incisor 11, the second inner incisor 21, the first incisor incisor 12, and the second incisor incisor 22 may be reduced.

In addition, in another embodiment, in order to further reduce the feeling of foreign body felt by the tongue, the thickness of the portion adjacent to the outer circumference of the cutout OP2 in the transparent cover 100 may become thicker as it moves away from the outer circumference of the cutout OP2. . That is, the transparent cover 100 may include a thickness reduction section in which the thickness becomes thinner as it approaches the outer circumference of the cutout OP2.

That is, the portion of the transparent cover 100 that covers the inner wall 12_i of the first side incisor 12 and the inner wall 22_i of the second side incisor 22 becomes farther from the outer circumference of the transparent cover 100. The thickness may increase gradually.

As a result, the tongue may naturally move along the inner wall 12_i of the first side incisor 12 and the inner wall 22_i of the second side incisor 22, thereby reducing foreign body feeling.

7 is a plan view of a transparent calibration device according to another embodiment of the present invention.

Referring to FIG. 7, the cutout OP3 is, in one embodiment, the cutout OP3 is the upper end 11_t of the first inner incisor 11 and the upper end of the second inner incisor 21 in the transparent cover 100. At least a portion of the inner wall 11_i of the first inner tooth 11 and the inner wall 21_i of the second inner front tooth 21 may be exposed. In addition, the incision OP3 exposes a portion of the upper end 12_t and the inner wall 12_i of the first incisor incisor 12, and the upper end 22_t and the inner wall 22_i of the second incisor incisor 22. Part of the).

The incision OP2 is the upper end portion 11_t of the first inner incisor 11 and the upper end portion 21_t of the second inner incisor 21 and the inner wall 11_i of the first inner incisor 11 in the transparent cover 100. ) And at least a portion of the inner side wall 21_i of the second inner tooth 21 are the same as described above with reference to FIG. 5. Therefore, detailed description thereof will be omitted.

In addition, the cutout OP2 may expose the upper end portion 12_t of the first side incisor 12 and the upper end portion 22_t of the second side incisor 22. As described above, it is the first inner incisors 11 and the second inner incisors 21 that feel the greatest sense of discomfort. Secondly, it is a first side incisor 12 and a second side incisor 22 that feel a large amount of foreign body. In one embodiment, when the incision OP3 exposes the upper end 12_t of the first prosthesis 12 and the upper end 22_t of the second prosthesis 22, the first prosthesis 12 and the second The foreigner feeling that the front incisors 22 feel can be reduced.

Correspondingly, when the cutout OP3 has a radial shape, the user's tongue may not contact the transparent cover 100 or minimize contact, thereby minimizing foreign body feeling.

In addition, in another embodiment, in order to further reduce the feeling of foreign body felt by the tongue, the thickness of the portion adjacent to the outer circumference of the cutout OP3 in the transparent cover 100 may become thicker as it moves away from the outer circumference of the cutout OP2. . That is, the transparent cover 100 may include a thickness reduction section in which the thickness decreases as it approaches the outer circumference of the cutout OP2.

That is, the portion of the transparent cover 100 that covers the inner wall 12_i of the first side incisor 12 and the inner wall 22_i of the second side incisor 22 becomes farther from the outer circumference of the transparent cover 100. The thickness may increase gradually.

4 to 7 have been described with reference to the lower jaw teeth for convenience of description, but are not limited thereto. That is, the transparent orthodontic device according to some embodiments of the present invention may be applied to the lower jaw teeth and / or the upper jaw teeth. In addition, when applied to the lower jaw teeth and upper jaw teeth at the same time, there is an advantage that can reduce the foreign body feeling due to the contact of the lower jaw front teeth and the upper jaw teeth.

8 is a perspective view of a transparent calibration device according to an embodiment of the present invention.

Referring to FIG. 8, the transparent calibration device according to an embodiment may include a color layer 200.

In one embodiment, the color layer 200 may be made of an opaque material. There may be a portion of the user's teeth that is to be hidden or aesthetically deteriorated. The color layer 200 may cover this, thereby improving the aesthetics of the user wearing the orthodontic device.

In an embodiment, the color layer 200 may be disposed on an inner side surface of the transparent cover 100.

That is, in the state coupled to the user's teeth, the color layer 200 may be disposed between the outer wall of the user and the transparent cover.

In one embodiment, the color layer 200 may have a shape corresponding to the shape of the outer wall of one tooth. For example, if the color layer for covering the canine, it may have a shape corresponding to the canine outer wall shape.

In one embodiment, the color layer 200 may be formed by applying a paint. The paint may include a color similar to natural teeth or a color excellent in aesthetics (eg, a color used in a whitening laminate procedure or the like).

To this end, the paint may include any one or more selected from the group consisting of inorganic titanium oxide (TiO 2), red iron oxide (Fe 2 O 3), yellow iron oxide (Fe 2 O 3), and pink erbium oxide (Er 2 O 3).

In one embodiment, the color layer 200 may be used for repairing lost or deleted teeth.

That is, as shown in FIG. 8, the void 300, which is a lost or deleted tooth, may be disposed on the tooth of the user. The color layer 200 may cover the void part 300 to make it appear that there is a tooth in the corresponding area.

In an exemplary embodiment, the color layer 200 may have a thin thickness so that a tooth corresponding to an area in which the color layer 200 is disposed is inserted. For example, the thickness of the color layer 200 may be 0.01 mm to 0.1 m.

However, when the blank portion 300 is formed as shown in FIG. 8, the color layer 200 may fill a portion corresponding to the blank portion 300 in the transparent cover 100 to serve as a tooth restoration. In some embodiments, when the interior space of the transparent cover 100 is maximally filled by the user's dentition, the desired corrective force may work properly. In other words, a void occupying more than a certain volume may act as an obstacle to correction.

When the color layer 200 is expanded to have the shape of a tooth generally expected to be in the void 300 and at least partially fill the transparent cover 100, the color layer 200 may be adjacent in the engaged state. Support your teeth to help correct.

To this end, the color layer 200 may include a material used for dental restoration. For example, resin or the like may be used as the material of the color layer 200.

As will be described in detail later, the color of the color layer 200 may be input to the input unit of the 3D printer and output by the output unit.

For naturalness and aesthetics, the color of the color layer 200 may be applied to the color of the adjacent tooth. To this end, in one embodiment, the scanning unit may extract two color codes of adjacent teeth of the tooth into which the color layer 200 enters. In the present specification, the 'color code' is a code for expressing a color numerically, and may be one selected from an RGB color code, a CMYK color code, and an HSB color code.

In detail, the scanning unit may provide a color code extracted from one point of one tooth and a color code extracted from one point of the other tooth. The controller may determine the color of the color layer 200 by extracting an average value of two color codes. The controller may input an average value to the input unit, and the output unit may output the color layer 200 based on the average value.

8 illustrates that the color layer is formed only on a portion corresponding to one tooth, but is not limited thereto.

In other embodiments, the color layer may be formed on two or more teeth.

In addition, in one embodiment, the color layer may be formed as a whole to correspond to the outer wall of all teeth of the user. That is, the color layer may be disposed on a portion of the inner surface of the transparent cover 100 that corresponds to the outer wall of the user's teeth. In this case, natural and bright dentitions, such as laminate procedures, can be seen from the outside. The reason why the user avoids the braces is uncomfortable, but the aesthetic reasons are large. This is because the aesthetics of a general calibration device are not good. As described above, if the color layer covers the user's teeth and artificially recognizes the ideal teeth, this problem can be solved.

Hereinafter, a method of manufacturing a transparent calibration device according to some embodiments of the present invention will be described. Some of the configurations described below may be the same as the configuration of the transparent calibration apparatus according to some embodiments of the present invention, and descriptions of some configurations may be omitted to avoid redundant description.
