[0013] Solution to the problem

[0014] According to the present invention, as a means for achieving the above-mentioned object, there is provided a marker formed integrally with an oral bracket, the basic feature of which is that it is technically constructed to include: a bracket, which is located in the oral cavity of a patient and is capable of IR tracking and CBCT imaging; and a marker part, which is connected to one side of the bracket and is exposed to the outside of the oral cavity when the bracket is placed in the oral cavity of the patient so as to track the coordinates of the bracket.

[0015] The marker part has a fixed joint integrally connected to the side surface of the bracket and a movable joint that rotates left and right at the fixed joint to adjust the angle of the marker part, wherein gears are formed at the upper end of the fixed joint and the lower end of the movable joint, respectively, and the angle of the marker part is adjusted and fixed according to the connection position of the gears.

[0028] Hereinafter, examples of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the examples described herein and can be implemented in various other embodiments. In addition, in order to clearly describe the present invention, parts not related to the description are omitted from the accompanying drawings.

[0029] Throughout the specification, when a certain part “includes” a certain configuration element, it means not to exclude another configuration element but may further include another configuration element unless specifically described otherwise.

[0030] Figure 1 is a stereoscopic view of a marker formed integrally with an oral support according to the present invention, Figure 2 is a stereoscopic view of a bracket and a fixing joint according to the present invention, Figure 3 is a partial stereogram of a fixed joint and a movable joint according to the present invention, Figure 4 is a plan view showing a reference line and an angle adjustment scale according to the present invention.

[0031] like Figures 1 to 4 As shown, the present invention is constructed to include: a bracket 100, which is located in the patient's mouth and is capable of IR tracking and CBCT imaging; and a marker part 200, which is connected to one side of the bracket 100 and is exposed to the outside of the mouth when the bracket 100 is placed in the patient's mouth so as to track the coordinates of the bracket 100.

[0032] The bracket 100 is used in dentistry and realizes the function of guiding to an implantation position to determine the implantation position of an implant. The bracket 100 used in the present invention has both a radiopaque marker 500 that can appear on a CT image and an IR marker 300 that can be recognized by an IR camera.

[0033] Therefore, the CBCT data and the design file of the stent 100 may be merged on the 3D software, and the actual position of the stent 100 may be tracked in real time.

[0034] The process of using the IR marker 300 and the radiopaque marker 500 can be briefly described as follows.

[0035] - CBCT imaging: When the stent 100 according to the present invention is placed in the oral cavity of a patient and CBCT imaging is performed, the radiopaque marker 500 formed on the stent 100 is recognized during the CBCT imaging.

[0036] - Merge the patient's data and the 3D data of the stent 100 by matching the radiopaque markers 500 in the CBCT data with the markers in the STL design file of the stent 100 stored on the 3D software. Use the merged data to design implant placement planning information using the 3DPlanning CAD software.

[0037] - IR camera (not shown): The IR camera is separately installed outside and recognizes the position of the IR marker 300 .

[0038] - IR marker: When the bracket 100 is placed in the patient's oral cavity, the bracket 100 is located in the oral cavity and the IR marker 300 is located outside the oral cavity. In this case, the IR camera recognizes the position of the IR marker 300 in real time and tracks the coordinates of the bracket 100.

[0039] - Then, the coordinates of the support 100 obtained by the IR marker 300 and the IR camera are transmitted to the 3D visualization software, and the position of the patient is displayed in real time on the 3D visualization software.

[0040] In the design for implementing this process, a plurality of IR markers 300 are formed at the end of the movable joint 220 of the marker part 200, and the coordinates of the IR markers 300 can be recognized in real time by the IR camera. In addition, in this design, radiopaque markers 500 are respectively formed on the upper ends of the fixed joint 210 and the movable joint 220 of the marker part 200 and on the side surface of the bracket 100, so that the radiopaque markers 500 are recognized during CBCT imaging.

[0041] The marker part 200 includes a fixed joint 210 integrally connected to the side surface of the bracket 100 and a movable joint 220 that rotates left and right at the fixed joint 210 to adjust the angle of the marker part 200. Gears 400 and 410 are formed at the upper end of the fixed joint 210 and the lower end of the movable joint 220, respectively, and the angle of the marker part 200 is adjusted and fixed according to the connection position of the gears 400 and 410. After the angle is fixed, the fixed state is maintained. In this angle adjustment structure, the angle needs to be adjusted according to the impression acquisition position of the bracket 100.

[0042] Here, in the drawings, a configuration is described as an example in which the marker part 200 can separate the fixed joint 210 and the movable joint 220 from each other to adjust the angle thereof. However, the present invention is not limited thereto, and it should be noted that, in the case where the angle does not need to be adjusted, the marker part 200 can be formed as a single body without separating the fixed joint and the movable joint from each other.

[0043] On the other hand, a portion where the fixed joint 210 and the movable joint 220 are connected is selected, a reference line 600 for determining an angle is formed at a selected portion of the upper end of the fixed joint 210, and an angle adjustment scale 610 is formed at the upper end of the movable joint 220 so that the rotation angle of the movable joint 220 can be finely adjusted. The reference line 600 and the angle adjustment scale 610 enable precise angle adjustment.

[0044] The necessity of the reference line 600 and the angle adjustment scale 610 is as follows.

[0045] In some cases, dental treatment and surgery are not performed immediately after CBCT imaging, and parts of the bracket 100 and the radiopaque marker 500 need to be separated from each other according to convenience. In these cases, when the bracket 100 and the radiopaque marker 500 are placed at the exact position (angle) imaged in the CBCT data, the position of the patient can be accurately identified during surgery. However, when the bracket and the radiopaque marker are placed at different positions (angles), the coordinate values ​​of the treatment and surgery may change, and medical accidents may occur. In this case, the reference line 600 and the angle adjustment scale 610 can achieve their functions in the above-mentioned case.

[0046] As mentioned above, the description provided above focuses on an example; however, the example is described only as an example, 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 implemented without departing from the inherent characteristics of the example. For example, each configuration element specifically described in the example may be modified to implement. In addition, the differences associated with these modifications and applications will be interpreted as being included within the scope of the present invention specified in the appended claims.
