Description

Technical Field

[0001] The present invention relates to an indirect bonding device and an indirect bonding method for a dental orthodontic device, and more particularly, to an indirect bonding device and an indirect bonding method for a dental orthodontic device that can easily discharge excess adhesive inside and enable an operator to recognize whether a fixture in the oral cavity is correctly fastened. Background Art

[0002] In order to correct malocclusion, an orthodontic device made of a material harmless to the body is bonded to teeth, and then a force of an orthodontic wire is applied to the device to treat the maloccluded teeth into normal occlusion. At this time, the above orthodontic device is called a bracket, and the treatment of using the corresponding bracket to correct malocclusion is called fixed orthodontic treatment or bracket orthodontic treatment.

[0003] In order to perform orthodontic treatment using the bracket as described above, the corresponding bracket must be bonded to the target teeth to be corrected. At this time, the applicable bonding methods are mainly divided into a direct bonding method and an indirect bonding method. The direct bonding method is a method in which an operator directly bonds a bracket to a required position of the target teeth to be corrected using tools such as forceps. The indirect bonding method is a method in which an arbitrary indirect bonding jig (InDirect Bonding Jig, hereinafter referred to as 'IDB Jig') is manufactured according to the oral structure of each subject and then directly fastened to the teeth of the subject to more easily and accurately bond the bracket. In recent years, the utilization rate of the indirect bonding method has gradually increased.

[0004] Figure 1 An existing general vacuum forming type indirect bonding jig is shown.

[0005] As shown in the figure, an existing general indirect bonding jig is simply applied in a form covering the teeth of a subject. In the case of using an existing indirect bonding jig, the amount of adhesive for bracket bonding may be large. However, at this time, the adhesive diffuses between the indirect bonding jig (IDB Jig) and the tooth surface, and the adhesive adheres excessively to the tooth surface.

[0006] In this case, in order to remove the excess adhesive in the corresponding part, after the operator separates the indirect bonding jig (IDB Jig) from the oral cavity, additional work is required to remove the excess adhesive attached to the corresponding tooth surface using a tool such as a bur. Moreover, in this process, there are problems of increasing the possibility of tooth damage and working time. In addition, the excess adhesive interferes with the fit between the jig and the teeth and becomes an obstacle, making it difficult to place the bracket at an accurate position (Bracket Placement) as planned by the operator.

[0007] Moreover, when using an indirect bonding jig (IDB Jig), since the jig covers the labial (buccal) surface, lingual surface, mesiodistal surfaces, etc., including the occlusal surface of the tooth, it is difficult to confirm the proper fastening state of the jig. This ultimately interferes with the correct fastening of the jig, increases the possibility of incorrect fastening, and also makes it difficult to accurately place the bracket, causing problems.

[0031] Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention can be implemented in various different forms and is not limited to the embodiments described herein. And, in order to clearly describe the present invention in the drawings, parts irrelevant to the description are omitted, and similar parts are denoted by similar reference numerals throughout the specification.

[0032] Throughout the specification, when a part is described as being "connected" to another part, this includes not only the case of "direct connection" but also the case of "indirect connection" with another member interposed therebetween. And, when a specific part is described as "including" a specific structural element, this means that other structural elements can be further included without excluding other structural elements unless otherwise specified.

[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0034] Figure 2 A perspective view of the indirect bonding device 1 for dental orthodontic appliances according to the present invention, Figure 3 and Figure 4 A top view for observing the exterior and interior of the indirect bonding device 1 for dental orthodontic appliances according to the present invention, Figure 5 A detailed view magnifying a part of the accommodating part 200 according to the present invention.

[0035] As shown in the figure, the indirect bonding device 1 for dental orthodontic appliances according to the present invention has a basic structure of a jig body part 100 and an accommodating part 200, and according to an embodiment of the present invention, may further include a discharge hole part 300 and / or a window part 400.

[0036] The jig body part 100 is a structure that constitutes the body of the indirect bonding jig, and can also be configured to cover the positive oral shape of the subject. That is, according to the needs of the surgery, it is selected from the shapes of the upper or lower jaws of the subject to form a shape that covers the surfaces of each tooth.

[0037] The receiving part 200 is a space formed inside the jig body part 100, and can be formed as a groove for receiving the orthodontic bracket to be bonded to the tooth surface of the subject. At this time, the receiving part 200 is formed corresponding to the number and position of the orthodontic brackets that need to be added corresponding to the lingual side and / or labial side of the tooth surface of the subject.

[0038] Generally, the indirect bonding device of the orthodontic device is manufactured by first placing the orthodontic bracket on a cast model obtained by simulating the teeth of the subject, and adding the above cast model relative to the upper surface. Generally, the work of simulating the teeth can be applied to the method of pouring alginate into the jig and reproducing the negative shape of the teeth by having the patient bite, and the method of putting an oral scanner into the mouth to scan and monitor the oral cavity of the subject.

[0039] Based on the cast model formed in the same structure as the oral structure of the subject in the above-described manner, the receiving part 200 of the present invention can be formed as a negative-shaped groove corresponding to the tooth surface to which the orthodontic bracket of the subject needs to be bonded.

[0040] The jig body part 100, which is the basic structure of the present invention, and the receiving part 200 formed inside the jig body part 100 are used as an indirect bonding jig (IDB Jig) for accurately bonding the orthodontic bracket to the target teeth for orthodontics in the form of vacuum forming.

[0041] At this time, preferably, the jig body part 100 and the receiving part 200 of the present invention can be composed of one or more materials, and are composed of flexible materials to be able to receive the orthodontic bracket.

[0042] Moreover, the jig body part 100 according to an embodiment of the present invention can be easily separated. That is, the surgical operator can appropriately divide and use the jig body part 100 of the present invention corresponding to the tooth surfaces and oral structures of various shapes of the patient.

[0043] In addition, the jig body part 100 according to an embodiment of the present invention can be formed of a transparent material that allows the interior to be seen through, and can be composed of various colors.

[0044] The indirect bonding device 1 for a dental orthodontic device according to an embodiment of the present invention is characterized in that it further includes a discharge hole portion 300.

[0045] Figure 6 And Figure 7 A detailed view showing an enlarged view of the discharge hole portion 300 of the present invention and cross-sectional views of various embodiments are illustrated.

[0046] As Figure 6 Shown, the discharge hole portion 300 may be formed by one or more holes penetrating the inner and outer portions of the jig body portion 100. The discharge hole portion 300 serves as a passage for discharging the above-mentioned adhesive from the inside of the device when an excessive amount of adhesive (resin) is added to the orthodontic bracket.

[0047] When using an indirect bonding jig, an excessive amount of adhesive is often added for bonding the orthodontic bracket. In this case, there is a problem that the adhesive that is not used for bonding the bracket due to the excessive addition diffuses between the indirect bonding jig and the tooth surface of the subject and adheres to the tooth surface.

[0048] At this time, in the indirect bonding device 1 for a dental orthodontic device according to an embodiment of the present invention, the discharge hole portion 300 penetrates the jig body portion 100 so that the portion of the receiving portion 200 in contact with the tooth surface of the subject and the orthodontic bracket is connected to the outside, so that the unnecessary excessive adhesive can be easily discharged to the outside of the device.

[0049] For this purpose, the discharge hole portion 300 according to an embodiment of the present invention may be formed as a plurality of through holes spaced apart by a predetermined distance according to the shape of the jig body portion 100. At this time, preferably, the discharge hole portion 300 is respectively provided corresponding to the positions of the grooves of the receiving portion 200 where the orthodontic bracket is formed.

[0050] As Figure 7 Shown, in the discharge hole portion 300 according to an embodiment of the present invention, the cross-section penetrating from the inner receiving portion 200 for receiving the orthodontic bracket to the outside of the jig body portion 100 may be formed in various shapes.

[0051] As Figure 7 As shown in (a) of, the discharge hole portion 300 according to an embodiment of the present invention may have a predetermined cross-sectional area.

[0052] As Figure 7 As shown in (b) of, the discharge hole portion 300 according to an embodiment of the present invention may be formed in a shape in which the cross-sectional area gradually narrows from the inner receiving portion 200 toward the outside of the jig body portion 100. That is, the cross-sectional area of the discharge hole portion 300 gradually narrows toward the outside, so that the excessive adhesive inside it is induced to gather in the discharge hole portion 300 along the narrowed cross-sectional area.

[0053] On the other hand, as shown in (c) of Figure 7 , the discharge hole portion 300 according to an embodiment of the present invention may be formed such that the cross-sectional area gradually narrows from the inner accommodating portion 200 toward the outside of the jig main body portion 100 and then gradually widens. After the excess adhesive accumulates in the discharge hole portion 300 along the gradually narrowing cross-sectional area, it can be more effectively discharged to the outside of the device through the relatively widening cross-section.

[0054] The dental orthodontic device indirect bonding apparatus 1 according to an embodiment of the present invention is characterized in that it further includes a window portion 400.

[0055] Figure 8 And Figure 9 are a detailed view of the window portion 400 of the present invention shown enlarged and cross-sectional views of various embodiments, respectively.

[0056] As Figure 8 shown, the window portion 400 is formed on the outer surface of the jig main body portion 100, is formed of a material capable of seeing through the inside, and serves as a lens for displaying the inside of the device. That is, the window portion 400 allows the surgical operator to visually confirm the inside of the jig main body portion 100 during the operation.

[0057] When using the indirect bonding jig, since the jig covers the labial (buccal) surface, lingual surface, mesial-distal surfaces, etc. including the occlusal surface of the tooth, it is difficult to confirm the proper state of the indirect bonding jig. This ultimately interferes with the correct fastening of the indirect bonding jig, increases the possibility of incorrect fastening, and is a disturbing factor that obstructs the accurate bonding of the orthodontic bracket.

[0058] At this time, in the dental orthodontic device indirect bonding apparatus 1 of the present invention, through the window portion 400, the surgical operator can visually confirm the fastening state with the tooth surface in the oral cavity of the subject to perform the operation. And the same is true when a casting model manufactured by simulating the tooth surface of the subject is connected to the device.

[0059] In addition, when removing the dental orthodontic device indirect bonding apparatus 1 of the present invention from the oral cavity or the casting model of the subject after fastening, the surgical operator can visually confirm the released state of the fastening, so it can be removed more easily.

[0060] For this reason, the window portion 400 according to an embodiment of the present invention may be formed in a plurality at a predetermined distance according to the shape of the jig main body portion 100.

[0061] As Figure 9 shown in (a) of , the window portion 400 according to an embodiment of the present invention may be formed as a lens having a predetermined thickness at the central portion and the edge.

[0062] As shown Figure 9 in (b) of Figure 9 , the window portion 400 according to an embodiment of the present invention may be formed as a concave lens whose central portion is thinner than the edge. Optically, a concave lens propagates light, so a large area can be seen at once, rather than making large objects look small. Therefore, through the window portion 400, the surgical operator can confirm the fastening state inside the jig body portion 100 in a wider range.

[0063] On the other hand, as shown Figure 9 in (c) of Figure 9 , the window portion 400 according to an embodiment of the present invention may be formed as a convex lens whose central portion is thicker than the edge. Optically, a convex lens is used to collect light, so small objects can be made to look larger, rather than seeing a small area. Therefore, through the window portion 400, the surgical operator can confirm the tooth surface as the surgical target in a further magnified state inside the jig body portion 100.

[0064] That is, the surgical operator selects any one of the embodiments of the window portion 400 of the present invention as described above according to the surgical needs to use, so that the dental orthodontic device indirect bonding device 1 can be fastened and removed more effectively.

[0065] In addition, the window portion 400 of the present invention may be formed in the form of a lens as described above, and is formed in a penetrating state without including materials such as additional lenses, so that the surgical operator can confirm the inside of the device.

[0066] Another technical feature of the present invention is an indirect bonding method for a dental orthodontic device.

[0067] The indirect bonding method for a dental orthodontic device of the present invention includes: a step of simulating the teeth of the subject to manufacture a casting model; a step of manufacturing a dental orthodontic device indirect bonding device 1 including a jig body portion having a shape covering the tooth portion of the casting model and a receiving portion as a space for receiving the tooth orthodontic bracket; a step of temporarily bonding the tooth orthodontic bracket on the receiving portion; a step of applying an adhesive to the tooth orthodontic bracket; a step of fastening the dental orthodontic device indirect bonding device 1 to the teeth of the subject; and a step of removing the dental orthodontic device indirect bonding device 1 from the teeth of the subject.

[0068] At this time, the main feature of the dental orthodontic device indirect bonding device 1 applicable to the indirect bonding method for a dental orthodontic device of the present invention is the dental orthodontic device indirect bonding device 1 further including the discharge hole portion 300 and / or the window portion 400 of an embodiment of the present invention as described above.

[0069] That is, the step of fastening the dental orthodontic device indirect bonding apparatus 1 to the teeth of the subject is characterized in that the adhesive that has been excessively added to the inside of the dental orthodontic device indirect bonding apparatus 1 is discharged to the outside.

[0070] And the step of removing the dental orthodontic device indirect bonding apparatus 1 from the teeth of the subject is characterized in that the operator visually confirms the inside of the dental orthodontic device indirect bonding apparatus 1 and removes it.

[0071] Therefore, in the indirect bonding method of the present invention, instead of attaching to the mouth of the moving patient, it is bonded to a jig made outside and the entire orthodontic bracket is transferred and bonded. As a result, compared with the case of directly bonding the orthodontic bracket, the orthodontic bracket can be accurately bonded in accordance with the set position and direction.

[0072] Moreover, regardless of the size of the open mouth or the size of the teeth, the difficulty of bonding the orthodontic bracket is significantly reduced. Therefore, the orthodontic bracket can be bonded without difficulty regardless of the proficiency of the operator, and the time required for bonding the orthodontic bracket can be greatly saved.

[0073] In particular, compared with the case of applying the existing indirect bonding device, the excessive adhesive can be easily discharged, so that tooth damage can be prevented and the working time can be shortened. And the operator can visually recognize the fastening state of the indirect bonding apparatus 1 on the target tooth, so that incorrect fastening can be prevented, and the jig can be very easily removed after the operation.

[0074] The above description of the present invention is for illustration. Those of ordinary skill in the technical field to which the present invention pertains can understand that without changing the technical spirit or essential features of the present invention, it can be easily modified into other specific forms. Therefore, it should be understood that the above embodiments are exemplary in all aspects and not restrictive. For example, each structural element described as a single form can be implemented in a dispersed form, and similarly, the structural elements described in a dispersed form can also be implemented in a combined form.
