Description

Orthodontic bite guide < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bite guide for orthodontic treatment, and more particularly, to a bite guide for orthodontic treatment which improves ease of use and stability of bonding in orthodontic treatment.

In general, malocclusion refers to an inaccurate occlusal relationship in which the teeth are not arranged in an array, or the engagement state of the upper and lower malleus is out of the normal position and is a functional and aesthetic problem.

On the other hand, when malocclusion occurs, there is a high possibility of causing damage to teeth, jaw joints, gum disease, etc., so orthodontic treatment for treating the malocclusion is performed.

In detail, the orthodontic treatment utilizes the property that the teeth move when receiving an external force, such as a device for suppressing or enhancing the development of the jawbone, and a device for gradually moving the tooth to a desired position.

Currently, the most widely used type is a fixed treatment method in which a device called a bracket is attached to a tooth and the tooth is moved by the tension of a wire such as an orthodontic wire or an elastic band, which can be used for various kinds of orthodontic treatment.

In detail, the brackets are each firmly attached to the surface of the tooth to be aligned, and the wires are fixed to interconnect the brackets. The teeth to be calibrated can be gradually moved by regulating the tension applied to the wire and variously adjusting the direction and size of the force applied to the wire. Accordingly, the orthodontic treatment is performed while the position and posture of the tooth to be aligned is changed by the tension of the wire and the tooth moves little by little.

At this time, when the anterior portion of the upper arch of the maxilla or the anterior portion of the mandible is opposed to the anterior portion of the arch opposing the anterior portion of the arch, the bracket attached to the anterior portion of the arch of the target collides with the anterior portion of the opposed arch. Accordingly, there have been many cases in which the bracket is separated from the anterior portion during mastication, and the soft tissue inside the oral cavity is wounded or swallowed together with food.

In addition, in the state where the anterior portions of the subject arch and the cervical arch are mutually engaged, it is difficult for the pressure applied through the elastic member such as the wire to be accurately transmitted to the correction target tooth, and the time required for calibration is increased, It is difficult to precisely control the temperature.

Conventionally, a method of applying resin to the chewing surface of the posterior portion has been devised to maintain the gap between the target arch and the cervical arch, but the resin in the viscous fluid state has a sufficient thickness in the direction of the gap between the target arch and the cervical arch There is a problem that it is difficult to be applied.

In addition, since the applied resin has a low bonding force to the target molar, the surface portion is formed in a rounded shape, and the pressing pressure through the mating mouth portion is loaded in a direction deviating from the water line direction of the bonding surface, . In addition, when the mating mating part contacted with the resin slips along the rounded surface part, pressure is generated in a direction in which the object arch and the mating arch are moved away from the normal mating position, so that the foreign body feeling during mastication is large, There was a problem.

Further, since the resin is generally provided to less than the strength of the teeth so as to prevent damage to the mating posterior part or the target posterior part, there is a problem in that it is difficult to stably maintain a gap between the target arch and the mating arch due to wear of the mating posterior part there was.

SUMMARY OF THE INVENTION [0006] In order to solve the above problems, the present invention provides a bite guide for orthodontic appliances improved in ease of use and stability of bonding during orthodontic treatment.

According to another aspect of the present invention, there is provided a method of correcting a tooth of a subject to be orthodonticized, the method comprising: A bonding support portion formed with an adhesive surface having an inner surface profile and adhered to the support target tooth; And a chewing surface of a supporting tooth opposed to the tooth to be supported protruding from an upper surface of the joining support for maintaining a calibration gap between the tooth to be calibrated of the subject to be orthodonticized and an opposed tooth to be opposed thereto, And a bite body portion having a deformation inducing groove recessed in an upper surface portion of the bite support portion so that deformation of the bite support portion is induced when the bite portion is separated from the support target tooth.

Wherein the deformation inducing groove is formed along the dental arch direction connecting the teeth to be supported and the adjacent teeth adjacent to the teeth to be supported and has both ends open to communicate with the outer periphery of the bite body, And an extension guide slit formed in a direction orthogonal to the tangent line of the dental arch so as to intersect with the slit and having a closed end portion which is pressed by the dental grip device at both ends.

Preferably, the extension guide slit is formed with an extension guide surface extending in the direction of the dental arch at a central portion intersecting with the reduction guide slit.

In addition, it is preferable that a mold stopper surface corresponding to a masticating surface profile of the supporting tooth is formed on the upper end of the bite body based on the three-dimensional image.

At this time, a concave-convex embossing portion is formed on the adhesive-guiding surface so as to increase the separation resistance against the applied dental adhesive, and the bonding support portion is provided with a groove And a discharge inducing hole is formed through the through hole.

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

First, the abutting support part is stuck to the supporting object teeth by tightly covering the chewing surface, and the bite body protruding from the upper surface part is pushed radially inward to come in through the free space in the reduction inducing slit opened toward the dental arch The teeth are deformed to be separated from the surface of the teeth to be supported and are easily separated, so that the joint stability and the ease of use of the product can be improved at the same time.

Second, by merely pressing both ends of the extension induction slit cross-disposed on the reduction induction slit, the pressing direction and the reduction direction of the reduction inducing slit are aligned so that an easy primary transformation is possible. However, Since the extended deformation is induced, the edge portion and the central portion of the joint support portion are successively separated completely by continuous pressing in the same direction, so that the usability of the product can be further improved.

Third, since the die pad provided on the upper surface of the bite body supports the chewing surface of the supporting tooth to provide a stable feeling of chewing feeling, the foreign body feeling is reduced, and the pressure generation in the oblique direction due to slipping during chewing, The separation of the adhesive layer and the burden on the jaw joint are reduced, so that the binding stability and the satisfaction of use of the product can be improved.

Fourth, an adhesive applied between the bonding support and the teeth to be supported is inserted into the embossed embossed portion and is separated from the surface of the tooth to be supported while maintaining the state of being bonded to the adhesive induction surface when the bonding support is deformed. The remaining adhesive can be minimized, and the removal work of residual adhesive and the resulting damage to the teeth can be reduced, so that the usability and satisfaction of the product can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a tooth guide for orthodontic treatment according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view showing a mounting state of a bite guide for a teeth correction according to an embodiment of the present invention, FIG. 2 is a perspective view showing a mounting state of a bite guide for a teeth correction according to an embodiment of the present invention, FIG. 4 is a bottom view of a tooth guide for orthodontic treatment according to an embodiment of the present invention; FIG. 4 is a perspective view of a tooth guide for orthodontic treatment according to an embodiment of the present invention;

As shown in FIGS. 1 to 4, a tooth guide 100 for orthodontic treatment according to the present invention includes a joint support portion 10 and a bite body portion 20.

Here, the bite guide 100 is provided inside the oral cavity of the subject to be orthodonticized to maintain a sufficient clearance gap between the to-be-aligned teeth 2a and the to-be-matched teeth 2f which are disposed opposite to the to-be- Means a device to be installed.

In this case, the tooth to be corrected (2a) refers to a tooth requiring orthodontic correction by dental deformation or malocclusion among the whole teeth of the subject's arch to be subjected to correction of the maxillary or mandibular heights. The orthodontic prosthesis 3) is actually a tooth to be installed.

The orthodontic prosthesis 3 installed in the orthodontic tooth 2a during chewing is prevented from being separated by the interference of the orthodontic tooth 2f or the orthodontic tooth 2b is inserted through the orthodontic prosthesis 3 It is preferable to reflect the current occlusal state between the to-be-corrected tooth 2a and the to-be-corrected tooth 2f so as to secure a space that can be deformed at the target position and angle according to the pressure.

At this time, the bite guide 100 is provided on the tooth 2b to be supported with little or no deformation at the time of orthodontic correction of the tooth 2a to be aligned. Here, the tooth 2b to be supported can be set as a tooth included in one of the object arches including the object tooth 2a to be calibrated or the confrontation arch including the correcting object tooth 2f, and the object tooth 2a ), It is preferable to set it as a molar portion having a wide and flat shape of chewing surface while being less likely to deform during orthodontic correction.

2 to 4, the bonding support portion 10 is provided in a rounded plate shape having a size to cover the chewing surface of the tooth to be supported 2b, and a profile corresponding to the chewing surface The adhesive surface 11 is formed and adhered to the tooth 2b to be supported via a dental adhesive such as a resin. Here, it is preferable that the size and the outer shape of the bonding support portion 10, and the profile of the adhesive-guiding surface 11 are set based on the three-dimensional image 1 obtained for the inside of the oral cavity of the subject to be orthodonticized.

In detail, the three-dimensional image (1) refers to three-dimensional outline data representing the inside of the oral cavity of the subject to be orthodonticized, and may be provided as an oral scan image of the target arch and the arch arch. Of course, such an oral scan image can be obtained by directly capturing an image of the inside of the mouth of the subject of orthodontic correction or indirectly capturing an image of the impression model obtained with respect to the interior of the oral cavity of the orthodontist.

At this time, the outline information of all the teeth included in the target arch and the antagonism arch is displayed in the three-dimensional image (1), and an orthodontic correction plan suitable for the subject of orthodontic correction is established based on the obtained three- And the orthodontic prosthesis 3 can be designed and placed virtually in the three-dimensional image 1 according to the established orthodontic plan.

Here, the fact that the orthodontic prosthesis 3 is virtually disposed means that the three-dimensional coordinate is calculated in a state where the orthodontic prosthesis 3 is installed on the orthodontic tooth 2a. Dimensional image information is displayed on the three-dimensional image (1).

Of course, the three-dimensional image 1 may be composed of only the oral scan image. In order to establish the orthodontic correction plan and to design the orthodontic prosthesis 3, information on the internal structure of the root, alveolar bone density, It is also possible to provide a matched image through registration of an image and an oral scan image.

At this time, a calibration gap can be set considering the positions and angles of the orthodontic prosthesis 3 and the orthodontic tooth 2f displayed in the three-dimensional image 1, The supporting object tooth 2b suitable for holding the calibration gap can be selected in the state where the opposing arch is lifted in accordance with the above-mentioned calibration clearance, and the various designing processes of the bonding support 10 and the bite guide 20 can be performed.

Here, the bonding support portion 10 is provided at a size corresponding to the mastication surface of the tooth 2b to be supported, and the middle portion of the mastic surface and the lingual and labial rims of the masticatory surface are wrapped As shown in FIG.

That is, both end portions of the bonding support portion 10 may be rounded along the lingual and protruding edges of the masticating surface, and may extend so as to surround the inner and outer surfaces of the teeth 2b.

At this time, by using the three-dimensional outer shape information of the tooth 2b to be supported which is set on the three-dimensional image 1, the joining support 10 having a shape to wrap the joining surface and the side surface connected to the joining surface can be accurately designed have.

As a result, the contact support area between the support target tooth 2b and the bonding support portion 10 is increased, and both ends of the bonding support portion 10 are hooked to the support target tooth 2b, .

That is, the pressure in the lingual and lateral directions applied to the bonding support portion 10 is not concentrated to the adhesive layer formed thinly between the bonding support portion 10 and the tooth to be supported 2b, And thus the phenomenon that the bonding support portion 10 and the tooth to be supported 2b are slipped and separated in the adhesive layer direction can be minimized. As a result, it is possible to stably support not only the vertical external force generated in the general chewing process but also the horizontal external force generated in the process of brushing or the like during the sleeping.

 The adhesion inducing surface 11 is provided with a profile corresponding to the chewing surface. That is, it is preferable that the adhesive inducing surface 11 is formed to have a surface gradient similar to that of the chewing surface, and that the chewing surface surface profile of the tooth to be supported 2b is inverted so as to match the chewing surface.

For example, in the case where the tooth to be supported 2b is a prefecture, the adhesive guiding surface 11 is formed so as to correspond to a chewing surface having a rounded concavo-convex surface in which the central portion is recessed and the rounded rim portion is protruded, And the rim portion may be formed with an upwardly recessed surface profile.

At this time, by using the three-dimensional outer shape information of the tooth 2b to be supported, which is set on the three-dimensional image 1, the adhesion guide surface 11, which is precisely matched to the surface shape and the wear state of the chewing surface, .

As a result, the area of adhesion between the surface of the tooth 2b to be supported and the bonding support portion 11 is maximized, and the dental adhesive applied between the support target tooth 2b and the bonding support portion 11 is a chewing surface And the adhesion-inducing surface 11, and the bonding stability of the product can be improved.

In addition, since the adhesive inducing surface 11 is provided with a profile that is inversely fused on the chewing surface, the portion of the chewing surface which is recessed so that the protrusion of the chewing surface is inserted and the portion protruding to be inserted into the depressed portion of the chewing surface, A latching structure can be formed. Accordingly, the water-splitting direction and the horizontal direction separation resistance in the adhesive layer direction can be simultaneously increased, and the bonding stability of the product can be further improved.

1 and 2, the bite body 20 includes a bite body 20 for holding the calibration gap between the tooth 2a to be calibrated to the orthodontic subject and the opposed tooth 2f facing the tooth, And supports the chewing surface of the opposing tooth 2e which protrudes from the upper surface of the supporting portion 10 and is opposed to the tooth to be supported 2b.

Of course, depending on the dentition form of the subject to be orthodontic, one or more teeth of the opposed arch may be contacted with one tooth to be supported (2b), so that the masticating surface of the supporting mating tooth is a mating surface But it is understood that it means a portion which is substantially in contact with the upper surface portion of the bite body portion 20. [

Here, the bite body 20 is preferably designed based on the three-dimensional image 1 obtained for the inside of the oral cavity of the subject to be orthodonticized. That is, the three-dimensional image (1) used for designing the orthodontic correction plan and orthodontic prosthesis (3) includes all the teeth of the confrontation arch including the target arch and the tooth to be occluded (2f) And the occlusal relationship between the teeth is displayed.

In addition, in the three-dimensional image (1), the object arch and the cervical arch are displayed as a virtual image in accordance with a calibration gap set in consideration of the positions and angles of the orthodontic prosthesis (3) and the orthodontic tooth (2f). At this time, when the support target tooth 2b suitable for the calibration gap maintenance is selected, the bonding support portion 10 corresponding to the surface profile of the support target tooth 2b is designed and the three-dimensional outer shape of the designed bonding support portion 10 Information can be virtually arranged on the three-dimensional image (1).

The fact that the bonding support portion 10 is virtually disposed means that the three-dimensional coordinates of the bonding support portion 10 are calculated in a state where the bonding guide surface 11 is fused to the surface of the tooth to be supported 2b And it is preferable to understand that the three-dimensional outer shape information of the joint support part 10 is imaged and displayed on the three-dimensional image 1.

At this time, when the bonding support portion 10 is virtually disposed, the bite body portion 20 is formed so as to correspond to the space between the support teeth 2e, which are virtually piled up from the upper surface of the bonding support portion 10 along the calibration gap. Can be set. That is, the height of the upper surface of the bite body 20 is preferably set according to the distance from the upper surface of the bonding support portion 10 to the chewing surface of the supporter tooth 2e.

Accordingly, the correcting gap can be stably maintained in a state in which the chewing surface of the supporting tooth 2e is supported on the upper surface of the bite body 20, The separation of the orthodontic prosthesis 3 is prevented, and the tooth 2a to be aligned can be stably and smoothly moved and corrected within a sufficient correcting gap.

The bite body 20 has a flat circular cross section, which is protruded from a central portion of the upper surface of the bonding support portion 10 covering the masticating surface, and the upper surface portion of the bonding support portion 10 It is preferable to have a maximum diameter within a range that does not deviate.

At this time, on the basis of the joint supporting portion 10 virtually arranged on the supporting object teeth 2b and the mating face of the supporting mating teeth 2e virtualized in the calibration gap on the three-dimensional image 1, Since the projecting direction of the portion 20 and the position of the upper surface portion 26 are designed, the support stability against the mastic surface of the supporting tooth 2e can be improved.

That is, the upper surface portion 26 of the masticating bite body 20 is brought into contact with the mating surface of the supporting tooth 2e in parallel with the mating supporting portion 10 in the state of the tooth 2b to be supported Pressure can be applied to the upper surface portion 26 of the bite body portion 20 in the direction perpendicular to the bite portion 20 and a stable dispersion of the adhesive layer provided between the bonding support portion 10 and the teeth to be supported 2b .

Thus, unlike in the prior art in which the chewing pressure of the supporting tooth 2e is concentrated in a diagonal or inclined direction on a part of the adhesive layer between the resin and the tooth 2b to be supported during the occlusion of the resin, ) And the tooth 2b to be supported, so that the bonding stability can be improved.

Since the bonding and mounting direction can be guided in such a shape that the bonding guide surface 11 of the bonding support portion 10 is matched with the mating surface of the tooth to be supported 2b, Can be accurately placed in the direction originally designed based on the three-dimensional image (1).

2 to 3, it is preferable that a marking part 25 is formed on the outer circumference of the bite body part 20 so that a reference value expression corresponding to the to-be-supported tooth 2b is displayed so that the mounting position is guided . Here, the reference value expression refers to the position of a tooth and the number assigned to each arch to distinguish the teeth.

That is, the marking portion 25 is formed in a groove or protruding protrusion shape recessed in the outer circumferential surface of the bite body 20, and the reference value expression is formed in the support target tooth 2b.

Thus, the bonding support portion 10 can be accurately installed on the predetermined support target tooth 2b, and the bonding and mounting directions can be guided in the process of bonding the adhesive-guiding surface 11 and the to-be-supported tooth 2b have. That is, since the bite body 20 can be installed in the correct position and direction so as to stably support the supporting tooth 2e, the calibration gap can be stably maintained and the installation convenience of the product can be improved .

At this time, the dental adhesive may be photocurable, and the bite body 20 and the bonding support 10 are preferably made of a light-transmitting material through which cured light of the adhesive is transmitted. As a result, the curing quality of the adhesive is improved, and visibility is reduced from the outside, thereby improving the aesthetics of the adhesive.

It is preferable that the deformation inducing groove 21 is formed in the upper surface 26 of the bite body 20 such that the deformation of the bonding support 10 is induced when the bite tooth 2b is separated from the tooth to be supported 2b.

The deformation inducing groove 21 may be formed in a straight slit shape that is recessed downward from the upper surface portion 26 of the bite body 20 and extends along the radial direction of the bite body 20 .

At this time, when the outer circumference of the bite body 20 is gripped through the crown remover and pressed radially inward, the inner space of the bending deformation groove 21 is reduced and the upper end of the bite body 20 is radially inward And the joint support portion 10 connected to the bite body portion 20 is deformed. That is, both ends of the bonding support portion 10 are sloped along the deformation direction of the bite body portion 20 in a state where the central portion of the bonding support portion 10 is supported on the center surface of the tooth to be supported 2b, Side surface of the to-be-supported tooth 2b. At this time, since the deformation pressure of the bonding support portion 10 is concentrated on the edge portion of the adhesive layer, the bonding guide surface 11 can be easily separated from the surface of the support target tooth 2b.

When the dental screwdriver or the like is inserted into the inner space of the deformation guide groove 21 and opened, the upper end of the bite body 20 is expanded and deformed in the radially outward direction and connected to the bite body 20 The bonding support portion 10 is deformed.

That is, the center of the bonding support portion 10 is raised along the deformation direction of the bite body portion 20 in a state where the rim of the bonding support portion 10 is supported on the rim side surface of the to-be-supported tooth 2b, Can be separated from the central portion surface of the base 2b.

At this time, since the deformation pressure of the bonding support portion 10 is concentrated at the central portion of the adhesive layer, the bonding guide surface 11 can be easily separated from the surface of the support target tooth 2b. In this way, while the joint support portion 10 maintains stable engagement, the bite body portion 20 is deformed at the time of pressing in the radial direction and can be easily separated, so that the usability of the product can be improved.

The deformation inducing groove 21 may include a reduction inducing slit 21a and an extension inducing slit 21b.

In detail, the reduction guide slit 21a is formed along the direction of the dental arch t connecting the support target teeth 2b and the adjacent teeth 2c and 2d adjacent to the support target teeth 2b, And an opening (23) communicating with the outer periphery of the bite body (20).

That is, the reduction guide slit 21a can be easily reduced and deformed when pressing toward the radially inward side in a shape in which both end portions in the dental arch direction are opened.

At this time, when the bite body 20 is pressed in the direction w orthogonal to the tangential line t1 of the dental arch t, the upper end of the bite body 20 is inserted through the clearance in the reduction guide slit 21a, The bonding support portion 10 connected to the lower end of the bite body 20 can be deformed to be spaced apart from the tooth to be supported 2b.

That is, both sides of the bite body 20 divided by the reduction guide slit 21a are in close contact with each other through the clearance of the reduction guide slit 21a to induce deformation of the bonding support portion 10 . At this time, in the state in which the center side of the bonding support portion 10 corresponding to the reduction inducing slit 21a is supported on the surface of the tooth to be supported 2b, the bonding support portion 10 connected to both sides of the divided byte body portion 20 Can be lifted from the surface of the tooth 2b to be released, and the engagement state through the adhesive can be released.

Further, the reduction guide slit 21a can guide the mounting direction of the bonding support portion 10. That is, the teeth to be supported 2b are guided through the marking portion 25 and the both end openings 23 of the reduction guide slit 21a are arranged in the direction of the adjacent teeth 2c and 2d, Can be installed in the correct direction. Accordingly, the joining induction surface 11 and the chewing surface can be easily engaged with each other.

The extension guide slit 21b is formed in a direction w perpendicular to the tangential line t1 of the dental arch t to intersect with the reduction guide slit 21a. At this time, a closed end portion 24 to be pressed by the dental grip device is formed at both ends of the extension inducing slit 21b. That is, the extension guide slit 21b is formed in a shape that intersects with the reduction guide slit 21a and has both ends closed, and both closed ends can be pressed by a dental grip device such as a crown remover or the like .

At this time, the reduction direction of the reduction guide slit 21a and the grip direction of the dental grip apparatus can be guided through the closed end portion 24. That is, when the end side closed end portion 24 of the extension guide slit 21b formed in the direction perpendicular to the reduction guide slit 21a is pressed, the reduction direction of the reduction guide slit 21a and the direction The shrinkage inducing slit 21a can be easily shrunk and deformed in a state in which the pressing direction is aligned.

Further, the extension guide slit 21b can be used for an expansion deformation through a dental flathead screwdriver or the like. That is, when the dental flathead screwdriver is inserted, both ends of the dental flathead screwdriver are not released from the inside of the expanded extension inducing slit 21b, so that the pressure in the opening direction can be accurately transmitted to the bite body 20.

When the closed end portion 24 is radially inwardly pressed, the rim portion of the bonding support portion 10 is separated. When the inside of the expansion inducing slit 21b is radially outwardly pressed, the center of the bonding support portion 10 The part is separated, and the joint support 10 can be completely separated by two operations.

At this time, the extension guide slit 21b is preferably formed with an extension guide surface 24a extending in the direction of the dental arch at a central portion intersecting with the reduction guide slit 21a.

Here, the extension guide surface 24a may be formed at a portion where the extension guide slit 21b and the reduction guide slit 21a intersect with each other, and the intersection portion may be formed to be roundly connected, It may be formed by tapering. Of course, it is also possible that the extension guide surface 24a is formed on the entire inner surface of the extension guide slit 21b as the extension guide slit 21b is extended toward the outer side of the dental arch as it goes toward the center. At this time, the extension guide surface 24a is kept separated from each other in the shrinking direction of the reduction guide slit 21a due to the round or inclined shape when the inner surfaces of the shrinkage inducing slit 21a are in contact with each other, It is possible to switch the additional external force exerted in the shrinking direction of the reduction contraction slit 21a to the outward direction of the dental arch t.

Accordingly, by simply pressing the closed end portion 24 radially inward, the reduction guide slit 21a is first shrunk and deformed, and when the expansion guide surface 24a is in close contact with the inner surface of the reduction guide slit 21a, The extension guide slit 21b can be secondarily expanded and deformed in the direction of the dental arch t.

That is, since the rim portion and the central portion of the bonding support portion 10 can be sequentially separated by continuous pressing in the same direction, the usability of the product can be further improved.

Unlike the prior art in which the material is limited by a dental resin or the like so as to have a predetermined strength to provide the support force of the support tooth 2e while having a predetermined adhesive force to the tooth 2b to be supported, 100 and the dental adhesive for providing the fixing force to the teeth 2b to be supported may be made of different materials so that the supporting force against the supporting tooth 2e is improved while having a more stable adhesive force, It can provide the base technology that can provide the tool.

FIG. 5 is a perspective view of a tooth guide for orthodontic treatment according to another embodiment of the present invention, and FIG. 6 is a bottom view of a tooth guide for orthodontic treatment according to another embodiment of the present invention. In the other embodiment, the basic structure except for the shape of the upper surface of the bite body 220 and the shape of the lower surface of the joint support part 210 is the same as that of the above-described embodiment, and thus a detailed description of the same structure will be omitted.

5 to 6, a mold stopper surface 226 is formed on the upper end of the bite body 220 to correspond to the stitching surface profile of the supporting tooth on the basis of the three-dimensional image 1, desirable.

That is, when the bonding support part 210 is virtually disposed on the supporting object teeth in a state where the object arch and the cervical arch displayed on the three-dimensional image 1 are virtually elevated along the calibration gap, The height of the bite body 220 may be set to correspond to the space between the raised supporting teeth.

At this time, a mold stopper surface 226 is formed on the upper surface portion of the bite body 220 so as to have a surface gradient similar to that of a chewing surface of the supporting tooth which is in contact with the tooth during chewing. Of course, it is more preferable that the die-like joint surface 226 is provided so as to have a surface profile that matches the chewing surface profile of the supporting tooth.

In this case, since one or more opposed arch tooth-side teeth can be brought into contact with one tooth to be supported according to the dentition form of the subject to be orthodonticized, the chewing surface profile of the tooth- And it is understood that it means a portion which substantially comes into contact with the upper surface portion of the body portion 220.

Thus, in a state in which the die holding surface 226 is mated with the chewing surface of the supporting tooth, it is possible to stably support the chewing pressure of the supporting tooth without slipping and to provide stable writing sensitivity, .

In other words, as the support slidably slides from the upper surface portion of the bodyside body 220, the pressure at the time of chewing is loaded on the bonding support portion 210 in an oblique direction, thereby separating the adhesive layer or imposing a burden on the jaw joint of the subject Discomfort can be minimized.

The embossed emboss part 212 may be formed on the adhesive guiding surface 211 to increase the separation resistance against the applied dental adhesive.

The concavo-convex embossing portion 212 is formed in a groove having a small area which is depressed upward from the adhesive inducing surface 211 and is formed so as to be distributed over the entire area of the adhesive inducing surface 211 .

That is, the adhesive applied between the bonding supporting portion 210 and the teeth to be supported is inserted into the concave embossing portion 212 and can be firmly coupled to the adhesive guiding surface 211. At this time, the bonding force between the adhesive and the adhesive-guiding surface 211 can be formed to be higher than the bonding force between the adhesive and the subject tooth.

In this way, when the bonding support portion 210 is deformed, the bonding agent is separated from the surface of the support target tooth in a state in which the adhesive is stably held in the bonding guide surface 211 in accordance with the adhesive force deviation through the embossed emboss portion 212 , The amount of adhesive remaining on the surface of the tooth to be supported can be minimized. Accordingly, after the separation of the bonding support part 210, the subsequent operation of scraping the residual adhesive by using a bur or the like is minimized, thereby improving the usability of the product. However, Since the risk of damage is reduced, the satisfaction of use of the product can be improved.

Meanwhile, the bonding support part 210 may be formed with a discharge inducing hole 213 communicating with the deformation inducing groove so as to discharge excess of the adhesive. At this time, the discharge inducing hole 213 may be formed so as to penetrate part of the convex-concave embossing portion 212 which is opposed to the deformation inducing groove, and may be provided as a separate hole separated from the concave- It is also possible.

Hereinafter, the discharge inducing holes 213 are provided in a pair of slit-like shapes intersecting each other in a shape similar to the shape of the deformation inducing groove.

At this time, when the adhesive agent is applied to the lower surface of the bonding support part 210 in a state of being adhered to the surface of the object tooth, the adhesive pressed by the surface of the object tooth naturally flows into the discharge inducing hole 213 Can be discharged. Accordingly, separation due to excessive adhesive or deviation in the mounting direction is minimized, and the bonding support portion 210 and the object tooth can be stably and tightly bonded.

In addition, since the adhesive disposed between the bonding support part 210 and the teeth to be supported and the adhesive flowing along the inside of the discharge guide hole 213 are connected and cured integrally, the bonding support part 210 and the supporting object teeth The bonding stability can be further improved.

At the time of deformation of the bite body 210 through the deformation inducing groove, the amount of the deformation of the joint supporting portion 210 may be increased through the discharge inducing hole 213 corresponding to the deformation inducing groove, (210) and the teeth to be supported can be smoothly separated.

As described above, the present invention is not limited to the above-described embodiments, and variations and modifications may be made by those skilled in the art without departing from the scope of the present invention. And these modifications fall within the scope of the present invention.
