The structure of the teeth, that is, the arrangement of teeth, is an important factor influencing a person's impression, and this impression can affect human relationships and social life. Accordingly, orthodontic treatment for the improvement of teeth, teeth, or facial skeleton along with plastic surgery is popular.

The above-mentioned orthodontic treatment can correct malalignment, for example, crooked teeth, and correct various skeletal inconsistencies that may occur during growth so that normal functions can be exerted. In addition, it can improve the facial line beautifully by changing the anatomical structure of the oral cavity.

Also, when abnormalities in the interlocking of upper and lower teeth or facial skeletal structure, especially in the jaw structure, are so severe that it cannot be treated with simple tooth movement, Growth Modification is used in adults with mild jaw structures in adolescence that do not complete growth. For moderate or more skeletal abnormalities, surgery to correct the abnormality of the jaw itself with surgery is sometimes applied along with orthodontic procedures.

The orthodontic treatment can be largely divided into labial correction and lingual correction. The labial correction is an orthodontic method in which a bracket used for orthodontics is attached to the labial and buccal surfaces of the teeth to perform orthodontic treatment, and the lingual Orthodontics is an orthodontic method that performs orthodontic correction by attaching brackets to the lingual side of the teeth.

The orthodontic treatment takes a long period of time, and various therapeutic effects such as improving the density of teeth in the anterior region or gapping between the incisors (open occlusion), or improvement of the palatal expansion or protrusion, or occlusion of the extraction space, can be realized.

The bracket base (11; Base) is a part attached to the teeth, and can be easily attached to the teeth and can be easily separated from the teeth without damaging the surface (A) of the teeth after orthodontic treatment is completed. That is, irregularities are sometimes applied to the tooth attachment surface.

And the bracket body 12, that is, the wire holder is a part into which the calibration wire is fitted, and the above-described wire holder 12 has a slot 13 into which a calibration wire, for example, an arch wire, is fitted. And, the wing 14 may be formed so that a ligation member such as a rubber band for binding of the calibration wire is wound.

In the bracket attached to each tooth, unique information for tooth movement, for example, a unique force application direction is set, and the bracket is located at a position set in the patient diagnosis and orthodontic treatment plan. It is important to be accurately attached, and if the above-mentioned bracket is attached to an incorrect position, it may cause improper tooth movement, resulting in incorrect treatment results.

The method using the above-mentioned bracket and orthodontic wire is the most commonly used orthodontic method, and the bracket 10 is a very important orthodontic appliance that transmits the force expressed from the orthodontic wire to the teeth, and is made of ceramic or metal material. Brackets of various manufactured structures are used in the field of orthodontics.

The bracket operation frame 100 is a structure detachable to at least one tooth of the patient to be corrected. In this embodiment, the bracket treatment frame 100 includes a tooth frame 110 and a bracket molding groove 120 .

The dental frame 110 is a negative-shaped structure having a shape in which the surface of the teeth to be corrected is engraved, for example, a frame of an empty intaglio structure in which the surface shape of the teeth is engraved. And the bracket molding groove 120 is formed integrally with the tooth mold 110 as a part for forming a bracket mold, that is, a mold for bracket molding.

More specifically, the bracket molding groove 120 is formed on the inside of the tooth frame 110 , and a bracket molding material, for example, resin for bracket molding, is formed inside the bracket molding groove 120 . is injected, a bracket 200 made of a resin material for supporting the orthodontic wire (hereinafter referred to as a 'resin bracket') may be molded in a predetermined portion of the bracket operation frame 100, that is, inside the bracket molding groove 120. . The bracket has various structures such as a slotted structure or a tubular structure, and a structure that is fixed to the tooth surface to support the orthodontic wire and transmit the force of the orthodontic wire to the teeth, that is, the wire support member is all included in the bracket.

A tooth contact surface 111 engraved according to the surface shape of the tooth to which the bracket is to be attached, that is, the bracket attachment tooth, is formed on the inner surface of the dental frame 110, and the tooth contact surface 111 is the resin bracket 200 for the patient. The tip portion of the crown has a engraved shape in order to be placed at a predetermined position of the tooth. More specifically, the tooth contact surface 111 forms an alignment reference surface of the resin bracket 200 so that the resin bracket 200 is disposed at a predetermined position on the tooth surface with respect to the end of the crown.

The tooth contact surface 111 preferably has a shape in which at least a portion of the surface shape of the crown end (hereinafter referred to as 'crown top') of the bracket-attached tooth is transferred (engraved) for accurate positioning of the bracket.

More specifically, the crown of the tooth (bracket attachment tooth) to which the resin bracket 200 is to be applied, for example, is manufactured in an engraved shape (intaglio) in which insulation of anterior teeth or an occlusal surface of posterior teeth is engraved, so that the crown of the tooth with the bracket The top may have a structure that engages with the tooth contact surface 111 and is covered by the tooth frame 110 .

In the case of a dental mold applied to the lower teeth, the crown top is the upper end of the tooth, and in the case of a dental mold applied to the upper teeth, the opposite is the case. The bracket treatment frame shown in FIG. 2 is a device applied to the upper teeth.

And the bracket molding groove 120 forms a molding space for the resin bracket 200, and the entrance (injection hole of the bracket molding material) of the bracket groove 120 is formed on the inner surface of the tooth frame 110 . do. The dental frame 110 covers the tooth surface to which the resin bracket 200 is attached. For example, when the resin bracket 200 is attached to the lingual surface of a tooth, the dental frame 110 has a lingual wall. , When the resin bracket 200 is a labial (buccal) bracket, the dental frame 110 has a labial (buccal) wall.

Although an embodiment for operating (fixing) the bracket 200, it is not limited thereto and may also be implemented as a structure for operating the bracket on the labial (buccal) side.

The bracket molding groove 120, only the entrance formed on the inner surface of the tooth frame 110 is open and the opposite side and the circumference are blocked so that the resin can be accommodated as it is until the resin is hardened. ) can be a structure.

For example, the bracket molding groove 120 may have an embossing structure protruding to the outside of the tooth frame 100 . The bracket operation frame 100 may be made of various materials such as a silicone material or a thermoplastic polyurethane (TPU) material, but it is natural that the material of the bracket operation frame is not limited thereto. The bracket operation frame 100 is made of a resin material, and a material that does not adhere well to an adhesive, for example, a material with low surface tension is good.

The bracket operation frame 100 may have a multi-layer structure, for example, the inner layer constituting the inner surface of the bracket operation frame 100 is made of the above-described thermoplastic polyurethane material, and the bracket operation frame 100 ) may have a layer structure of two or more layers made of polyethylene terephthalate (PET) material.

And, as described above, the resin is injected/cured into the inside of the bracket molding groove 120 to form a resin bracket, that is, the resin bracket 200, and the resin bracket 200 is the bracket operation frame. (Positioning) at a set position of the patient's teeth while being mounted on (100).

The resin bracket 200 can be molded using various types of resins, such as composite resin for dental aesthetic restoration, as a material, and the composite resin for aesthetic restoration is a well-known material in the dental field and manufactured by various companies. Since it is commercially available, an additional description is omitted.

However, for the effective implementation of the present invention, the greater the difference in surface tension (surface energy, unit: dynes/cm) between the material of the resin bracket and the material of the bracket treatment frame is, for example, the surface tension is 5-10 or more. The difference is good for minimizing or preventing the phenomenon of sticking together (sticking phenomenon) during the molding process of the resin bracket. The bracket operation frame 100 has low adhesiveness by an adhesive and has a lower surface tension than the resin bracket 200 so that the resin bracket can be easily released, and is preferably made of a material harmless to the human body, for example, dental resin. Of course, an appropriate release material according to the material of the resin bracket and the bracket operation frame may be pre-treated in the bracket molding groove.

And in this embodiment, the tooth frame 110, as in the example of FIG. 2, forms a dental arch shape and may be implemented in the form of a mouthpiece made of a resin material, each with at least one tooth may be divided into a plurality of engraved parts.

For example, the tooth frame 110 may include an anterior tooth frame 100a, a left molar frame 100b, and a right molar frame 100c, but the division structure of the tooth frame 110 is limited thereto. no. Of course, the dental frame is not divided into a plurality of parts and is integrally formed, for example, the anterior teeth frame 100a, the left molar frame 100b, and the right molar frame 100c described above are not separated from each other and are integrally connected. Alternatively, after being integrally manufactured, it may be cut and divided into a plurality of parts.

Figure 2 (a) is a photograph showing an example in which the bracket operation frame 100 is manufactured on the real model 300 that embodies the maxillary teeth (upper teeth) of the patient as it is, (b) of Figure 2 is the bracket operation frame ( 100) is an inverted photo to show the inside.

Next, with reference to FIGS. 5 to 7, an embodiment of a method for manufacturing a bracket operation instrument having the above-described bracket operation frame will be described.

The bracket molding step (S100) includes the step of forming the resin bracket 200 by injecting resin into the bracket molding groove 120 . And before the bracket forming step (S100), a frame manufacturing step (S30) of manufacturing the above-described bracket operation frame is performed, and before the frame manufacturing step (S30), a step (S20) of preparing a tooth model is performed. .

The frame manufacturing step (S30) may include manufacturing the bracket operation frame in a shape in which the tooth model is engraved by using the tooth model.

The tooth model preparation step (S20) is a step of preparing any one of a real model tooth model and a virtual 3D tooth model in which a bracket model for orthodontic wire support is disposed on the surface of each tooth. For example, a real tooth model such as a plaster model on which a real bracket model is placed is prepared, or a virtual 3D tooth model in which a virtual bracket model (B) is placed on a virtual tooth through computer 3D modeling can be prepared. .

6 is an image showing a virtual 3D tooth model in which a virtual bracket model (B) is disposed on the lingual side of the tooth through 3D modeling, and a real tooth model (300; see FIG. 2) based on this is an RP (Rapid Prototyping) It can be manufactured by a rapid prototyping machine, such as a machine, or a 3D prototyping device such as a 3D printer. For example, as described above, when the shape data of a 3D dental model designed on a computer is transmitted to a 3D modeling device such as a rapid prototyping machine or other 3D printer such as a RP (Rapid Prototyping) machine, the above-mentioned 3D modeling device is the Based on the shape data of the 3D tooth model, the 3D tooth model can be implemented as a real thing.

That is, the tooth model on which the virtual 3D bracket model is placed may be designed through 3D computer modeling, and as a more specific example, the tooth model may be designed on the computer by the CAD/CAM method, and obtained by 3D computer modeling. Based on the three-dimensional shape data of the tooth model, the real tooth model 300 (refer to FIG. 2A ) may be manufactured.

A thermocompression bonding transfer device (for example, German FORESTADENT's model name TRACK) may be used to manufacture the bracket operation frame 100 based on the real model 300, and the above-described thermocompression bonding device and the dental thermoplastic sheet (S) ) types and products are variously known in the dental field, so an additional description thereof will be omitted.

Of course, instead of the real model 300 manufactured based on the shape data by 3D modeling described above, the real bracket model (for example, a ready-made metal bracket) is placed on the tooth part of the real tooth model, such as a plaster model that reproduces the patient's teeth. or ceramic bracket) to prepare a real model tooth model on which the real bracket model is placed, and then, as described above, a bracket treatment frame can be manufactured through the method of attaching the thermoplastic sheet (S) to the real model tooth model. can

In another way, after the bracket operation frame 100 is also designed through computer modeling, the shape data of the bracket thistle 100 is transmitted to the above-described three-dimensional molding apparatus, and the bracket operation frame 100 is manufactured You may.

That is, after designing a bracket operation frame having a structure that covers the tooth part and the bracket model part with a predetermined thickness in the 3D tooth model described above, the shape data of the teeth and the shape data of the bracket model are invariant, and in the virtual bracket operation frame By removing the area where the virtual tooth part and the bracket model overlap, the shape data of the bracket operation frame can be extracted. This process can be performed by using the Boolean function.

Hereinafter, with reference to FIGS. 8 and 9 , a procedure (bracket molding and tooth surface attachment) of the bracket using the above-described bracket operation frame 100 will be described.

First, when a resin bracket molding material is injected into the bracket molding groove 120 of the bracket operation frame shown in (a) of FIG. 8 and hardened, as in the example shown in FIG. The resin bracket 200 described above is molded in the inside. That is, the bracket model (B) can be copied as it is by the bracket molding groove.

And after the adhesive is applied to the tooth surface portion to which the resin bracket is to be attached and/or the base surface of the resin bracket 200, as in the example shown in FIG. 111) that is, the resin bracket 200 that is mounted on the patient's tooth T exposed above the gum G through the bracket alignment reference plane, and whose position is set based on the tooth contact surface 111 of the dental frame ) is precisely placed at a preset position (bracket mounting position) on the tooth surface.

Next, when the attachment of the resin bracket 200 is completed, the bracket operation frame 100 is separated/removed from the patient's tooth T, as shown in FIG. The resin bracket 200 remains fixed to the tooth T. 8 is a cross-sectional view showing the process of applying the resin bracket to the molars (molars).
