The present invention relates to a medical imaging apparatus, and more particularly, to an oral multi-vision system and a control method thereof that can accurately show the oral state of the patient during the procedure.

In general, dental treatment does not allow the patient to see the dental condition being treated. However, if necessary, the doctor reflects the tooth to be treated on the mirror and shows it to the patient and can explain the tooth condition, but the patient cannot see his or her teeth during the treatment. Recently, with the development of technology, a camera and a lighting device are installed in a pen-shaped bar, and the rod can be inserted into the oral cavity to obtain a dental image and show the tooth to the patient through a monitor. The lighting device has the disadvantage of being able to show the patient's dental condition before or only after treatment and not being able to show his or her dental condition to the patient during the treatment.

In other words, most of the currently developed dental lighting fixtures or intraoral imaging devices are unable to photograph the patient's teeth during the procedure of dental care and treatment and thus cannot show the patient's teeth to the patient during the dental procedure.

Accordingly, an object of the present invention is to solve the problems of the prior art, and the oral multi-vision system that allows both the patient and the doctor to show the patient's oral cavity and teeth condition in real time even after the dental examination and treatment and treatment and The control method is provided.

In order to achieve the above object, oral multi-vision system according to an embodiment of the present invention comprises a pair of opening holder for holding and holding both sides of the lips; A link unit connecting the opening holders; Mounting plates extending from each of the opening holders; A plurality of lamps installed on the mounting plate; A plurality of cameras are provided on the mounting plate.

The oral multi-vision system includes an input device for receiving a user's command; A display device for displaying an image photographed by the camera; Supply power to the lamp and the camera, adjust the brightness of the lamp according to the user's command input through the input device, and selectively turn on / off the cameras, and images of the camera selected according to the user's command And an image processing unit and a main body unit for supplying bays to the display device and adjusting the resolution and size of the display image according to the user's command.

The control method of the oral multi-vision system according to the present invention is a pair of opening holder for separating and gripping both sides of the lips, the link portion connecting the opening holder, the mounting plate extending from each of the opening holder, on the mounting plate In the control method of the oral cavity multi-vision system including a plurality of lights to be installed, and a plurality of cameras installed on the mounting plate, the lamp and the camera disposed in the mouth by supplying power to turn on the lights and the camera Receiving an image photographed by; Displaying a menu screen including an upper and lower teeth row layout, a left / right selection item, and an enlargement / reduction selection item on a display device; Selecting an image of a camera photographing the selected tooth and displaying the selected tooth on the display device when the user selects a specific tooth from the upper and lower tooth row arrangements through an input device; Enlarging or reducing the resolution and size of the image data to be supplied to the display device when the user selects the enlargement / reduction selection item through the input device; When the user selects the left / right selection item through the input device, one of the image of the camera photographing the left side of the tooth selected by the user and the image of the camera photographing the right side of the selected tooth is selected. And supplying the selected image to the display device.
