The oral image generation unit is for generating a three-dimensional image of a mouth of a patient and includes a photographing unit, a template image storage unit for providing a basic template image for converting an image photographed by the photographing unit into a three- And an image generating unit for generating a three-dimensional image of the patient's mouth through the photographed image of the photographing unit and the selected template image.

The photographing unit photographs a mouth image of a patient, and the image generating unit generates a three-dimensional image through a basic template image and an image photographed by the photographing unit. That is, based on the basic template image, the presence of the tooth, the position information of the tooth, and the shape information of the tooth are acquired in the oral state of the patient, and a three-dimensional image reflecting such information is generated.

Referring to FIG. 2, the process of generating the three-dimensional image will be described in more detail. First, one template image corresponding to the oral cavity of the patient is selected from the basic template images stored in the template image storage unit.

For example, the template image may be classified based on the presence or absence of wisdom teeth. The template image in which the wisdom tooth exists is a 3D template image including 32 teeth. In the case of a template image that does not include wisdom teeth, 28 teeth And may be a 3D template image included.

The selection of the template image may be directly determined by the doctor who performs the procedure, or may be automatically selected based on the oral image of the patient photographed by the image generating unit.

If a template image that is most similar to the patient's oral structure is determined according to various conditions such as the patient's tooth condition, age, sex, and the like, the photographed image photographed by the photographing unit is matched with the teeth on the template image. If a specific tooth is not matched, the tooth can be judged as a non-existent tooth. Through this matching procedure, each of the teeth of the patient includes the wisdom teeth 1 to 32 or the wisdom teeth For non-template images, it can be indexed from 1 to 28.

Then, three-dimensional coordinate information of the patient's teeth matched based on the template image is obtained.

In order to determine each indexed tooth position information, tooth-to-tooth distance information is acquired based on a plurality of oral images of the patient, and position information of each tooth can be obtained in three-dimensional coordinates based on the distance information.

And acquires correction information of the tooth shape of the patient matched based on the template image.

The image generating unit generates a three-dimensional oral image of the patient by correcting the template image selected based on the position information and the shape correction information of each tooth through the steps described above.

The tooth fixing unit generates the tooth fixing unit 100 for fixing the patient's mouth during the dental procedure based on the three-dimensional image acquired by the oral image generating unit.
