In describing the embodiments, when it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the embodiments, the detailed description thereof will be omitted.

The tooth scanning method according to an embodiment of the present invention may be performed by a tooth scanning device.

As shown in FIG. 1, the tooth scanning apparatus may include a scanner composed of an X-ray tube 110 and an image detector 120, a distance sensor 130, and a controller 140.

The X-ray tube 110 may project X-rays toward the teeth 101 of the patient 100. At this time, the X-ray tube 110 may be replaced with an X-ray source or an X-ray projector capable of projecting X-rays toward the teeth 101.

The image detector 120 may receive an X-ray projected from the X-ray tube 110 and transmitted through the tooth 101. In addition, the image detector 120 may generate an image of the tooth 101 by analyzing the received X-ray. In this case, the image detector 120 may be shaped in the shape of a plate through which X-rays can be incident at a predetermined width and height, as shown in FIG. 1.

The distance sensor 130 may measure the distance between the image detector 120 and 101. In this case, the distance sensor 130 may be coupled to the inside of the image detector 120 or to one side of the image detector 120.

The controller 140 may correct the position of the scanner including the X-ray tube 110 and the image detector 120 so that the distance between the image detector 120 and the tooth 101 is maintained.

Specifically, the controller 140 may compare the distance between the image detector 120 and the tooth 101 measured by the distance sensor with a reference distance. When the distance between the image detector 120 and the tooth 101 is less than the reference distance, the controller 140 may move the position of the scanner so that the image detector 120 is separated from the tooth 101.

At this time, since the X-ray tube 110 and the image detector 120 included in the scanner may be coupled with a fixed distance between each other as shown in FIG. 1, the image detector 120 in the controller 140 When the position of the scanner is moved to be spaced apart from 101, the X-ray tube 110 may move toward the tooth 101 by the distance the image detector 120 is separated from the tooth 101.

In addition, when the distance between the image detector 120 and the tooth 101 is the same as the reference distance, the controller 140 may maintain the position of the scanner.

In addition, when the distance between the image detector 120 and the tooth 101 exceeds the reference distance, the controller 140 may move the position of the scanner so that the image detector 120 approaches the tooth 101.

The arch 210 may have various sizes and shapes depending on the patient as shown in FIG. 2. Therefore, when the path of the scanner is set according to the arch 210 displayed in the center of FIG. 2 and a panoramic image of a patient having the arch 210 displayed on the left side of FIG. 2 is generated, the image when photographing the anterior portion of the patient Since the detector 120 is excessively close to the patient's teeth 101, the precision of the image may be lowered.

Accordingly, the controller 140 determines a path to generate an image of each of the teeth from one molar tooth to the other molar tooth of the patient with the distance between the image detector 120 and the tooth 101 as the reference distance, and the determined path By moving the scanner according to the shape of the patient's arch, and the path optimized for the patient's oral structure, it is possible to perform a scan. At this time, the scanner horizontally moves according to a path determined by the controller 140, and may generate a panoramic image of the patient's teeth according to the shape of the patient's arch and the patient's oral structure.

In addition, as shown in the class 2 (Class II) and class 3 (Class III) of FIG. 2, depending on the patient, the maxillary and the mandible may have an oral structure 220 that does not engage. In this case, the distance sensor 130 may measure the distance between the image detector 120 and the tooth 101 based on the tooth protruding outward from the maxilla and the mandible.

You can also have the patient bite a bite block. In this case, since the bite block is located between the upper and lower jaw of the patient, the distance sensor 130 may measure the distance between the image detector 120 and the bite block as the distance between the image detector 120 and the tooth 101.

The tooth scanning device determines the movement path of the scanner so that the distance between the patient's teeth measured by the distance sensor and the scanner is maintained, so that the scanner moves in a path optimized for the shape or size of the patient's arch and scans the patient's teeth. I can.

Reference numeral 310 is an example in which the distance between the image detector 120 and the tooth 101 measured by the distance sensor 120 coupled to the side of the image detector 120 is the same as the reference distance. At this time, the controller 140 does not change the position of the scanner, so that it is projected from the X-ray tube 110 and the X-ray tube 110 that project X-rays toward the patient's teeth 101 to pass through the teeth 101. The image detector 120 receiving the X-ray may maintain an optimized distance from the tooth 101.

320 is an example when the distance between the image detector 120 and the tooth 101 measured by the distance sensor 120 coupled to the side of the image detector 120 is less than the reference distance as shown in FIG. 3. At this time, since the image detector 120 was too close to the tooth 101, and the X-ray tube 110 is too far apart from the tooth, the image detector 120 is larger than the actual size of the tooth 101 and an unclear tooth image Can be created.

Accordingly, the controller 140 may move the position of the scanner so that the image detector 120 is spaced apart from the tooth 101. At this time, the controller 140 may move the position of the scanner until the geometric position between the X-ray tube 110, the image detector 120, and the tooth 101 becomes equal to 310.

330 is an example of a case where the distance between the image detector 120 and the tooth 101 measured by the distance sensor 120 coupled to the side of the image detector 120 exceeds the reference distance. At this time, since the image detector 120 was too spaced apart from the tooth 101 and the X-ray tube 110 was too close to the tooth, the image detector 120 would generate a tooth image that is smaller than the actual size of the tooth 101. I can.

Accordingly, the controller 140 may move the position of the scanner so that the image detector 120 approaches the teeth 101. At this time, the controller 140 may move the position of the scanner until the geometric position between the X-ray tube 110, the image detector 120, and the tooth 101 becomes equal to 310.

At this time, position 1, position 2, and position 3 may be positions of a scanner such that a distance between the image detector 120 and a tooth is a reference distance, respectively.

In step 420, the controller 140 controls the scanner including the X-ray tube 110 and the image detector 120 to move horizontally in the order of position 4, position 5, and position 6, so that the right teeth of the patient You can create a panoramic image of the image. In this case, the positions 4, 5, and 6 may be positions of the scanner such that the distance between the image detector 120 and the teeth becomes a reference distance, respectively.

In addition, the image detector 120 may generate a panoramic image of all teeth of the patient by combining the panoramic image generated in step 410 with the panoramic image generated in step 420.

5 is an example of a process of correcting an angle of a patient's scanner according to an embodiment of the present invention.

The tooth scanning apparatus may include an angle sensor 540 that measures an angle of a bite block 510 located between the upper and lower jaws of the patient.

In addition, the angle sensor 540 is installed on the same plane as the image detector 120 to measure an angle between the side surface of the byte block 510 and the image detector 120.

At this time, since the angle of the byte block 510 measured by the angle sensor 540 is based on the image detector 120, the angle sensor 540 is also inserted into the image detector 120 or in the image detector 120. Can be combined.

In addition, the controller 140 may correct the angle of the scanner so that the angle of the byte block measured by the angle sensor 540 is perpendicular to the image detector 120.

In addition, the tooth scanning apparatus may further include a laser irradiator 530 for irradiating a laser beam to the bite block 510. In this case, the angle sensor 540 may generate an incident image by photographing a laser beam irradiated to the side of the bite block 510. In addition, the angle sensor 540 may measure an angle between the laser beam included in the incident image and the side surface of the bite block 510.

The tooth scanning device controls the angle of the scanner so that the angle between the bite block held by the patient and the scanner measured by the angle sensor is a right angle, so that the scanner can scan the patient's teeth at an angle optimized for the patient's oral structure. .

The angle sensor 540 of FIG. 5 or the laser irradiator 530 may be included in the tooth scanning apparatus shown in FIG. 1.

In addition, when the distance between the image detector 120 and the tooth 101 measured in step 610 does not exceed the reference distance, the controller 140 may not move the position of the scanner.

In step 660, the scanner may generate an image of the tooth by photographing the patient's teeth 101 at the positions determined in steps 620 to 650. Specifically, the X-ray tube 110 of the scanner projects X-rays toward the patient's teeth 101, and the image detector 120 receives the X-rays transmitted through the teeth 101 to obtain an image of the teeth 101. Can be generated.

In step 670, the controller 140 may check whether or not all teeth have been photographed. At this time, when all the teeth are photographed, the controller 140 may end the tooth scan. If there is an unphotographed tooth among the patient's teeth, the controller 140 may perform step 680.
