Technical Field

[0001] The present invention relates to a dental bracket, and more particularly, to a dental bracket including a handle and a clamp which are used by being detachably coupled to a main bracket body according to a use purpose, and which enable dental treatment and surgery to be performed safely and accurately. Background Art

[0002] An implantation process for replacing teeth includes making a gingival incision to expose alveolar bone, and then forming a hole in the alveolar bone, wherein a fixture is implanted into the hole using a drill. A bracket can be used as an auxiliary tool to guide the surgeon during the drilling work of forming the hole, the position of the hole formed in the alveolar bone and the placement direction of the fixture.

[0003] The bracket includes: a guide hole 1a into which a drill is inserted when a hole is formed in the alveolar bone; a bracket guide 1b which guides the position of the drill; and a bracket support 1c which supports the bracket guide. Depending on the number and position of target teeth for the implantation process, the bracket support may be formed to cover all teeth, or may be partially formed to cover only adjacent teeth and adjacent gingival surfaces close to the surgical target teeth.

[0004] The bracket is designed by a software program and output through a 3D printer, etc. to be produced as an actual product based on the design result. According to the prior art, the bracket guide is designed to have a set height regardless of the length of the fixture (i.e., the drilling depth), and the drilling depth is determined by the length of the drill used in the operation.

[0005] According to the above-mentioned related art, it is inevitable to use drill bits having various lengths in accordance with the length of the fixture. Therefore, the number of drill bits included in the surgical kit used in the implantation operation increases, which leads to the inconvenience of using a plurality of drill bits at the same time according to the type of the fixture implanted in the operation. The increase in the number of drill bits not only causes inconvenience to surgeons and patients, but also becomes a factor that increases the purchase cost of the surgical kit and causes difficulty in its management.

[0031] According to an example of the present invention, a patient-specific stent is provided in the form of a kit.

[0032] refer to Figures 1 to 7 , the present invention is a dental bracket, which includes a main bracket body 100, an elastic clip 300 and a light-curable resin 200. In addition, a handle 400 and a clamp 500 are used, which can be detachably connected to the main bracket body 100 according to the purpose of use.

[0033] The main support body 100 is located in the maxillary arch or the mandibular arch, except for the treatment target or surgical site in the same maxillary arch and the mandibular arch, and has a corresponding square connection notch 110, which enables the corresponding handle 400 or the clamp 500 to be selectively detachably connected to the main support body according to the purpose. In addition, the main support body 100 has a corresponding assembly hole 120, and the elastic clip 300 is inserted into the assembly hole 120 to be connected to the upper end of the main support body. Figure 1 and Figure 2 As shown, the bracket is constructed with two identical main bracket bodies 100, each of which has a square connection recess 110 and an assembly hole 120, and a pair of two parts having the same construction are connected to each other by an elastic clip 300 to be used.

[0034] like Figure 3 As shown, the elastic clip 300 is coupled to the upper end of the main bracket body 100 to achieve the function of imparting elasticity to the main bracket body 100. In this regard, the elastic clip 300 has an inverted "U"-shaped body, and both lower end portions are formed to be inclined inwardly, so that when the lower end portion of the elastic clip 300 is forced to be inserted into and coupled to the assembly hole 120 formed at the upper end of the main bracket body 100, the main bracket body 100 smoothly tilts inwardly.

[0035] The configuration of the inwardly inclined main bracket body allows the handle 400 to have a pliers-like shape when the handle is coupled to the main bracket body 100 , so that the clamping and opening movement of the main bracket body 100 can be easily performed on the tooth side.

[0036] The light-curable resin 200 is formed on the corresponding inner wall of the main bracket body 100 and realizes the function of obtaining a tooth impression.

[0037] The light-curable resin 200 has a surface film 210 formed on the surface of the light-curable resin, and the surface film 210 suppresses the light-curable resin 200 from intruding between teeth during the acquisition of the tooth impression. After the tooth impression is acquired, the impression acquisition area of ​​the light-curable resin 200 is cured by a light curing device (not shown). The surface film 210 has a film shape, the inside of the surface film 210 is filled with the light-curable resin 200, and the surface film not only hygienically protects the filled light-curable resin 200 from the outside, but also suppresses the light-curable resin 200 from excessively intruding into the undercut between the teeth.

[0038] The handle 400 and the clamp 500 that can be detachably coupled to the main bracket body 100 have respective different functions. When the handle 400 or the clamp 500 is coupled to the main bracket body 100, the bracket is fully constructed and used as a kit. The sealed kit product contains the handle 400, the clamp 500, and the main bracket body 100 fully assembled in a sealed package and is sold on the market, and the sold kit product is opened to be used as a disposable bracket for dental treatment.

[0039] The handle 400 detachably coupled to the main support body 100 has a corresponding connection portion 410 at the lower end, which is detachably coupled to the square connection recess 110, and the coupled handle is configured to make the main support body 100 overcome the elastic force of the elastic clip 300 and separate from each other toward the right and left sides, respectively. When the handle 400 is coupled to the main support body 100, a clamp-like structure is formed, such as Figure 5 In other words, the main support body 100 is tilted inwardly due to the elastic clip 300, and the handles 400 are separated from each other outwardly.

[0040] In the above state, when the handle 400 is pressed inward, the main bracket body 100 overcomes the elasticity of the elastic clip 300 and enters a state in which the main bracket body is separated from each other toward the right and left sides. In this state, when the handle 400 is released after the bracket is located in the maxillary arch or the mandibular arch (usually, the opposite natural teeth, anchor pins, abutments, crowns, dentures, gums, etc.), the elasticity of the elastic clip 300 causes the main bracket body 100 to enter a clamped state on the tooth side except for the treatment target and surgical site in the same maxillary arch and mandibular arch. In this state, a tooth impression is obtained by the light-curing resin 200. After the tooth impression is obtained, the light-curing resin 200 is cured by a light-curing device.

[0041] The clamp 500 detachably connected to the main bracket body 100 has a fastening member 510 threadedly connected to the upper portion of the clamp and tightly screwed by the fastening member to prevent the main bracket body 100 from moving, and the clamp has corresponding tight contact portions 520 formed at the lower portion and in tight contact with the square connection recesses 110, respectively.

[0042] The clamp 500 has an inclined surface 530 on one side of the upper end, and the inclined surface 530 allows the oral cavity to be smoothly opened. In addition, the inner surface of the close contact portion 520 has a rounded shape, so that when the close contact portion 520 is in close contact with the square connection recess 110, close tightening can be smoothly performed by the close contact portion 520 of the rounded shape.

[0043] The main purpose of the clamp 500 constructed as described above is to prevent the separated main bracket body 100 from moving or falling off to increase its angle. In this regard, when taking a dental impression, the handle 400 is detached from the main bracket body 100, such as Figure 7 As shown, the close contact portion 520 of the clamp 500 is located on the side of the square connection recess 110, and then the fastening member 510 is fastened, thereby suppressing the movement of the main bracket body 100 and increasing the fixing force. The clamp 500 constructed as described above is used during dental treatment and surgery.

[0044] At the same time, it should also be noted that such a configuration can be implemented, where, for example Figure 8 As shown, the camera 600 is disposed on the side of the clamp 500, and the camera can image the inside of the patient's oral cavity in real time during treatment and surgery.

[0045] As mentioned above, the description provided above focuses on the embodiments; however, the embodiments are described only as examples, and the present invention is not limited thereto. In addition, a person skilled in the art to which the present invention belongs may find that various modifications and applications of the present invention not illustrated in the description provided above may be obtained without departing from the essential features of the embodiments. For example, each configuration element specifically described in the embodiments may be modified to achieve. In addition, the differences associated with these modifications and applications should be interpreted as being included within the scope of the present invention specified in the appended claims.
