The user device 100 acquires image data of the interior of the mouth of the subject who needs an artificial tooth procedure and transmits the image data to the electronic device 200. To this end, the user equipment 100 may perform communication such as ling term evolution-advanced (LTE-A), long term evolution (LTE), wideband code division multiple access (WCDMA) The image data that is transmitted to the electronic device 200 may include a 3D shot image and an oral scan image of the interior of the subject's mouth. To this end, the user device 100 may perform wireless or wired communication with a CT scanner and an oral scanner. If the user can not acquire an oral scan image for the inside of the mouth of the client because the oral scanner is not connected to the user apparatus 100, the user can acquire the gypsum model for the inside of the oral cavity and send it to the manager of the electronic device 200 have.

The electronic device 200 is an apparatus used by an administrator to determine a dental prosthesis. The electronic device 200 determines a prosthesis necessary for a prosthetic dentist's procedure using a CT image and an oral scan image received from the user device 100. If the electronic device 200 does not receive an oral scan image from the user device 100, the electronic device 200 acquires an oral scan image using a gypsum model of the interior of the mouth of the subject.

More specifically, the electronic device 200 generates a three-dimensional image by matching a CT shot image and an oral scan image. The electronic device 200 selects a fixture image for at least one fixture to be placed in the mouth according to an input from the manager, and places the selected fixture image in the three-dimensional image. At this time, the fixture image may be disposed at a position where the artificial teeth procedure is required among the inside of the wearer's mouth. The electronic device 200 places an abutment image for at least one abutment associated with the placed fixture image in the fixture image. The electronic device 200 determines a crown suitable for the placement position based on the tooth arrangement around the placement position shown in the three-dimensional image and the appearance information of the abutment image arranged in the fixture image. As such, the electronic device 200 can determine a dental prosthesis including a fixture to be placed at the placement position, an abutment coupled to the fixture, and a crown coupled to the abutment.

At this time, the three-dimensional image includes a placement position in which an artificial tooth is required to be implanted in the oral cavity. The control unit 260 places the fixture image for at least one fixture at the placement position. The control unit 260 places at least one abutment image related to the disposed fixture image in the fixture image. The control unit 260 determines a crown suitable for the placement position based on the tooth arrangement around the placement position shown in the three-dimensional image and the appearance information of the abutment image disposed in the fixture image. The control unit 260 can determine a dental prosthesis including a fixture to be placed at the placement position, an abutment coupled to the fixture, and a crown coupled to the abutment.

More specifically, the control unit 260 receives the 3D photographed image and the oral scan image of the interior of the subject's mouth from the user device 100 through the communication unit 210. [ The control unit 260 scans the gypsum model for the inside of the subject's mouth from the image obtaining unit 220 and receives the obtained oral scan image if the oral scan image is not received from the user device 100. [ The control unit 260 generates a three-dimensional image by matching the 3D photographed image and the oral scan image. The control unit 260 displays the generated three-dimensional image on the display unit 240. At this time, the controller 260 may display a three-dimensional image of a part of the inside of the oral cavity on the display unit 240 about a position where the artificial tooth is to be placed in the oral cavity. When displaying a three-dimensional image, the controller 260 can display information such as a position, a diameter, an orientation, and a depth of a fixture, on which a fixture as a base for placing an artificial tooth, is to be placed.

When the three-dimensional image is displayed, the control unit 260 calls the digital library stored in the memory 250, and displays at least one fixture image included in the digital library on the display unit 240. At this time, the control unit 260 can receive the tooth number corresponding to the placement position from the input unit 230. The control unit 260 may extract a fixture image for at least one fixture corresponding to the inputted tooth number from the digital library and display the fixture image on the display unit 240. The control unit 260 selects a fixture image to be placed at the placement position among at least one fixture image displayed on the display unit 240 based on the signal received from the input unit 230. [ The control unit 260 can overlay the selected fixture image on the three-dimensional image displayed on the display unit 240. [ For example, the control unit 260 can overlay the fixture image on the three-dimensional image, and arrange the fixture image at the fixture position. At this time, the control unit 260 can adjust the arrangement position of the fixture image by the input of the input unit 230.

The control unit 260 arranges a fixture image in the three-dimensional image, and extracts an abutment image for at least one abutment that can be combined with the fixture image disposed in the digital library, and displays the abutment image on the display unit 240. The control unit 260 selects an abutment image to be combined with the fixture image arranged in the three-dimensional image among the abutment images based on the signal received from the input unit 230. [ The control unit 260 can overlay the selected abutment image on the fixture image displayed on the display unit 240. [ At this time, the control unit 260 can adjust the arrangement position of the abutment image by the input of the input unit 230. [

The control unit 260 determines the appearance of the crown suitable for the placement position based on the tooth arrangement around the placement position shown in the three-dimensional image and the appearance information of the abutment image arranged in the fixture image. The control unit 260 generates a crown image based on the determined outline of the crown. The control unit 260 calculates horizontal or vertical distances from a plurality of predetermined reference points on the outer surface of the crown image to the outer surface of the abutment image, and sets the degree of deflection to a minimum value among the calculated distance values. In this case, the deflection degree refers to a portion where the interval between the crown image and the abutment image is the narrowest based on the reference point, and a higher deflection degree can ensure a sufficient thickness between the crown and the abutment. Accordingly, the control unit 260 can determine that the higher the degree of deflection of the abutment, the higher the suitability. The control unit 260 may further display suitability according to the degree of deflection in the abutment image. When the selection completion signal for the abutment image arranged in the fixture image is received from the input unit 230, the control unit 260 determines the fixture image, the abutment image, and the crown image as the final dental restoration. As described above, according to the present invention, it is possible to more easily determine a prosthesis to be placed at a position where an operation of an artificial tooth is required among the oral cavity of a patient.
