[0034] Hereinafter, preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings.

[0035] FIG. 3A is a perspective view of a dental support block according to an embodiment of the present disclosure, FIG. 3B is an exemplary view showing a screen in the case of supporting a user's face on a dental support block according to an embodiment of the present disclosure, and FIG. 3C is an exemplary view showing a screen in the case of supporting a user's face on a dental support block 100 of the present disclosure. First, referring to FIGS. 3A and 3B, the dental support block 100 of the present disclosure includes a jaw protuberance support portion 110, a pedestal 120, a sliding operation portion 130, and an upper surface mounting portion 140.

[0036] The mental protuberance support portion 110 is a portion which comes into contact with a mental protuberance part of a user when the user moves his or her face forward to capture an image of teeth or dentition. Therefore, the mental protuberance support portion 110 may serve to guide movement forward and positioning when the user captures an image of the teeth or dentition.

[0037] The pedestal 120 is a portion located at the bottom of the mental protuberance support portion 110 and attached to a dental imaging apparatus to support the user's face. Here, a portion of the pedestal 120 may be in contact with and support a lower portion of the user's mental protuberance and serve to stably support the user's face when the image of the teeth or dentition of the user is captured.

[0038] The sliding operation portion 130 has of a cylindrical rod structure having a diameter smaller than the mental protuberance support portion 110, and a partial lower portion thereof may enter or leave from the inside of the mental protuberance support portion 110 in a sliding manner through a groove provided in the mental protuberance support portion 110. This is to adjust a shape of the dental support block 100 to fit the user's facial structure because each user has different facial structures or shapes and different distances between noses and mental protuberances. In addition, the sliding operation portion 130 may have a scale 132 on a surface thereof to check a position of the sliding operation portion 130 after the support block 100 is adjusted according to the user's facial structure and used. Therefore, after capturing an image of the teeth or dentition by adjusting the sliding operation portion 130 according to his or her facial structure, the user may check a positional relation between the sliding operation portion 130 and the mental protuberance support portion 110 by the scale 132. Thereafter, when an imaging is performed again afterward, the user may easily adjust the position of the sliding operation portion 130 according to his or her facial structure.

[0039] The upper surface mounting portion 140 is a portion bent in an “L” shape from an upper end of the sliding operation portion 130, which comes into contact with a part under a nose and a philtrum part of the user. The upper surface mounting portion 140 may be long or short in length depending on the user's facial structure and may be configured to be slidable.

[0040] After brining the mental protuberance support portion 110 into tight contact with his or her mental protuberance part, the user may bring the upper surface mounting portion 140 into contact with the part under the nose and the philtrum part by adjusting the sliding operation portion 130 in an up-down direction to adjust a shape of the support block 100 according to his or her facial structure.

[0041] The dental support block 100 of the present disclosure may be formed of transparent or colored plastic, carbon fiber, or synthetic resin. The synthetic resin may include a nylon resin, polycarbonate resin, a polyethylene resin, an acrylonitrile-butadiene-styrene (ABS) resin, or the like. Also, the dental support block 100 may be formed of a mixture of a carbon fiber and a synthetic resin.

[0042] When the user captures an image using the dental support block 100 of the present disclosure, the user may bring an end portion of the upper surface mounting portion 140 into close contact with the philtrum part under the nose and bring a front part of the mental protuberance into contact with the mental protuberance support portion 110 as shown in FIG. 3C, and in this state, a base part of the lower jaw may be stably supported by the pedestal 120. In this case, the upper jaw (maxilla) and the lower jaw (mandible) of the user may be in a natural occlusal state, and thus imaging may be performed in the accurate occlusal state.

[0043] FIG. 4 is a perspective view of a dental support block according to another embodiment of the present disclosure. Referring to FIG. 4, the dental support block 100 of the present disclosure may include a mental protuberance support portion 110, a pedestal 120, a sliding operation portion 130, and an upper surface mounting portion 140. These elements may be integrally configured or may be separately configured and coupled through a main body coupling portion 150. That is, in a state where the main body coupling portion 150 is fixed to the dental imaging apparatus, the mental protuberance support portion 110 supporting the user's jaw part and the pedestal 140 are coupled as one component to one side of the main body coupling portion 150 and the upper surface mounting portion 140 supporting a part under the nose or a philtrum part of the user and the sliding operation portion 130 may be coupled as one component to an upper portion of the main body coupling portion 150. Of course, the mental protuberance support portion 110 and the pedestal 120 may be separately coupled to the main body coupling portion 150.

[0044] As such, in case where the mental protuberance support portion 110, the pedestal 120, the sliding operation portion 130, and the upper surface mounting portion 140 are configured as individual components or configured to be coupled through one or more components, the dental support block 100 may be configured in various combinations by changing a size or shape of required components according to the user's facial shape.

[0045] FIG. 5 is an exemplary view showing a screen when a user captures an image using the dental support block 100 according to an embodiment of the present disclosure. Referring to FIG. 5, the dental support block 100 of the present disclosure is located at a face mounting portion such that an oral part of the user faces an X-ray light source of the imaging apparatus to capture an image of the head and neck, jaw joint, teeth or dentition, and the like through the dental imaging apparatus.

[0046] Here, the support block 100 of the present disclosure is configured to support the user's nose and the mental protuberance part of the user. However, since the user may move the face in the directions of up, down, left, and right, and thus, the support block 100 may include a face support frame 200 serving to fix the user's face.

[0047] The face support frame 200 may include a front frame 210 for supporting a front part of the user's face and a rear frame 220 for supporting a rear part of the user's face. The front frame 210 and the rear frame 220 may be integrally or separately formed.

[0048] The front frame 210 is open in a middle portion of a front surface thereof with respect to the front of the user for image capturing but has a circular structure along a circumference of the face so that the user may bring his or her face into close contact therewith in a forward direction. Here, when the user brings the face into close contact with the front frame 210 in the forward direction, the rear frame 220 may be brought into close contact with the back of the user's face and fixed to the user's face using a belt or the like so that the user's face may not move backward.

[0049] A process in which the user captures an image of the head and neck, jaw joint, teeth or dentition, and the like using the support block 100 of the present disclosure may be performed as follows.

[0050] First, the user may place the upper surface mounting portion 140 at a part under the nose and the philtrum part of the user by adjusting the sliding operation portion 130 of the support block 100 and brings the mental protuberance support portion 110 into close contact with the user's mental protuberance part so as to be in contact with the user's mouth part. Here, the support block 100 may be located such that the user's mouth part faces the X-ray light source of the dental imaging apparatus. Since the support block 100 of the present disclosure is not a structure bitten in an oral cavity of the user using teeth, the user may maintain a natural oral structure as usual. Therefore, the oral structure of the user as usual may be reflected as it is in treating teeth or manufacturing correcting or assisting devices.

[0051] Thereafter, the front frame 210 and the rear frame 220 may be attached and fixed to the user's face so that the user is located in a fixed form for capturing an image of the head and neck, jaw joint, teeth or dentition, and the like. In this state, an oral structure such as a user's teeth or dentition is captured by X-rays using the dental imaging apparatus.

[0052] FIG. 6 is an exemplary view of a screen when a dental support block according to an embodiment of the present disclosure is mounted on a dental imaging apparatus. Referring to FIG. 6, the dental support block 100 of the present disclosure may be used in a 3D CT apparatus such as a cone beam CT. In addition, the support block 100 of the present disclosure may be configured as an integral component provided together with the dental imaging apparatus or may be configured as an independent component which can be separately attached to various dental imaging apparatuses. In addition, as shown in FIG. 4, when the dental support block 100 is configured in an assemblable form, the dental support block 100 may be configured to include the main body coupling portion 150 attached to the dental imaging apparatus and a plurality of components which can be coupled to the main body coupling portion 150.

[0053] As described above, in case where an image of the head and neck, jaw joint, teeth or dentition, and the like of the user is captured using the dental support block of the present disclosure, the teeth or dentition of the user can be treated or an auxiliary device may be manufactured by reflecting the natural oral structure of the user as usual as it is.

[0054] Although the embodiments of the present disclosure have been described above with reference to the accompanying drawings, a person skilled in the art to which the present disclosure pertains will understand that the present disclosure may be implemented in any other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of the present disclosure is defined by the appended claims, rather than the detailed description, and should be construed as including all modifications and variations derived from the meaning and scope of the claims and concept equivalent thereto.
