Hereinafter, the configuration of the dental image providing device 1 having the above-described features will be described with reference to FIG. 1.

Referring to FIG. 1, a dental image providing device 1 according to an embodiment includes a data acquisition unit 10, a storage unit 12, a control unit 14, an input unit 16, and an output unit 18. do.

The data acquisition unit 10 acquires dental image data including at least one dental object. Dental objects include teeth, bones, maxillary sinus, nerves, TMJ, airways, and implants. Dental image data may be a two-dimensional image or a three-dimensional image. In the case of a three-dimensional image, a three-dimensional image can be acquired in a three-dimensional format from the beginning, or a three-dimensional image can be obtained from a two-dimensional image. Additionally, in the case of a two-dimensional image, it may be created in a two-dimensional format or may be an image obtained from a three-dimensional image. Dental image data includes CT data, scan data, etc. The data acquisition unit 10 executes dental image data in a program or loads data stored in a web page or server.

CT data uses CT (Computed Tomography) to generate tomographic images of the patient's head, and each tomographic image can be combined into one to obtain a three-dimensional image. The acquired CT data may be stored in the storage unit 12.

Scan data is data containing information on actual teeth, including damaged teeth. The scan data may be tooth model scan data obtained by scanning a plaster model created in imitation of the patient's mouth with a 3D scanner, and an impression modeled after the patient's mouth may be obtained using a 3D scanner. ) may be impression body scan data obtained by scanning. As another example, it may be oral scan data obtained by scanning the inside of a patient's mouth using a 3D intra-oral scanner. The acquired scan data may be stored in the storage unit 12.

The storage unit 12 stores various data, such as information necessary to perform the operation of the dental image providing device 1 and information generated according to the operation. Dental image data of individual patients is stored in the storage unit 12 according to one embodiment, and when simulating dental treatment, image data of a specific patient among all image data can be provided to the control unit 14 upon user request. . At this time, the storage unit 12 stores the image of the upper row of teeth and the image of the lower row of rows of each individual patient, and the image of the upper row of rows and the image of the lower row of rows that match the image data of a specific patient are stored in the storage unit 12 according to the user's request. ) can be provided. In addition, the CT data images and scan data images of the upper and lower teeth can be matched according to the user's request and provided to the control unit 14.

The input unit 16 receives a user manipulation signal. For example, a tab screen display request for displaying a tab screen corresponding to at least one dental object among a plurality of tab screens is input through the user interface. At this time, the user interface may be provided to imaging software or certain software that is linked to the imaging software (for example, hospital business management software, etc.). Here, the tab screen display request may include at least one of a screen change request from video software and a screen change request including a call to video software from other linked software.

The output unit 18 displays a tab screen. When the control unit 14 generates a first image rendered in a first direction and a second image rendered in a plurality of second directions using the dental image data acquired through the data acquisition unit 10, the output unit 18 displays at least one of the generated first image and second image on the tab screen. The tab screen is a screen classified according to the dental object corresponding to the purpose of providing the image, and refers to one tab displayed on the entire current screen. For example, the tab screen includes the Tooth tab screen, Bone tab screen, Temporomandibular joint (TMJ) tab screen, Airway tab screen, and Implant. It may include a tab screen, Endo tab screen, Multi Planar Reformation (MPR) tab screen, etc. Examples of bone tab screens include the Bone-maxillary sinus tab screen and the Bone-Nerve tab screen.

The output unit 18 can display a screen for user convenience. For example, a first image rendering a predetermined dental object in a first direction may be displayed on the tab screen. Alternatively, second images rendered by rendering a predetermined dental object in a plurality of different second directions may be displayed at once. The first image may be a 3D image that has been previously converted to the first direction. The second image may be a 3D image viewed from a second, different direction.

The control unit 14 renders at least one dental object of the dental image data acquired through the data acquisition unit 10 and outputs it through the output unit 18. For example, the controller 14 may generate a first image by rendering a predetermined dental object in a first direction. The generated first image is displayed on the tab screen corresponding to the dental object through the output unit 18. As another example, the control unit 14 may generate second images in which a predetermined dental object is rendered in a plurality of different second directions. The second image is displayed on the tab screen corresponding to the dental object through the output unit 18. The user can analyze teeth, bones, maxillary sinus, neural tube, jaw joint, airway, implant, endo, multi-angle reconstruction, etc. through at least one of the first image and the second image generated through the control unit 14.

For example, a second image of a predetermined dental object viewed from a plurality of different second directions is configured to be displayed on one screen through the output unit 18. Through this screen, users no longer need to rotate the image to view dental objects. This will allow users to check structures or lesions at a glance without any additional user manipulation when diagnosing a patient, which will lead to a reduction in diagnosis time.

As another example, the control unit 14 configures a screen optimized for the purpose of providing images. In other words, it does not simply provide multiple screens equally, but provides specialized screens according to the purpose of providing video.

For example, on the tooth tab screen, the screen is configured to provide images in 6 directions for a single tooth: Mesial, Distal, Buccal, Lingual, Root, and Top, allowing the overall shape and lesion of the tooth to be checked at once. , For multiple teeth, the screen is configured to provide images in four directions: Buccal, Lingual, Root, and Top, allowing the overall shape and lesions of the teeth to be checked at once. The bone-maxillary sinus tab screen is mainly intended for viewing for implant surgery or checking for inflammation, so it does not provide images in 6 directions, but rather displays the screen in the Sagittal (Bucco-Lingual Axis: BA) direction, where shapes and problems can be easily seen. The screen is configured to provide a large screen in the Coronal (Mesio-Distal Axis: MA) and Axial (Arch Axis: AA) directions for auxiliary purposes. The MA cross section can be used with the same meaning as the Cross cross section, the BA cross section can be used as the Parallel cross section, and the AA cross section can be used with the same meaning as the Axial cross section.

As another example, by configuring a screen that has been automatically edited (e.g., cropped) in advance to fit the dental object to be viewed and controlling it to be displayed through the output unit 18, the user does not have to use image design tools such as clipping. You can achieve your desired goal without it. You can create a screen with automatic editing (e.g. Clipping, Opacity) applied to various dental objects such as the maxillary sinus, inferior alveolar nerve canal, overall bone shape, TMJ, etc.

The control unit 14 displays a view mode selection interface on the screen through the output unit 18, and can selectively display or hide a predetermined image according to a user-selected input signal from the input unit 16 through the view mode selection interface. .

When the user wants to check in detail or make fine adjustments on the screen, he or she can check the image in detail or make fine adjustments by performing an operation of selecting a predetermined dental object through the input unit 16 on the screen. For example, when a user selects the maxillary sinus area or neural canal area on the bone tab screen, an image showing the selected maxillary sinus area or neural canal area can be displayed.

For example, on the implant tab screen, the user can drag and move fixtures displayed in the image, and in the image, the user can move the fixture in the desired direction by using the fine adjustment tool or dragging the fixture. can be rotated and moved.
