Description

A three-dimensional reference plane on a CT image and a three-dimensional reference plane on a CT image formed by the three-dimensional reference plane made by the same}

More particularly, the present invention relates to a face frame for forming a three-dimensional reference plane on a CT image and a three-dimensional reference plane on the CT image formed by the face frame.

In order to realize predictable diagnosis and precise surgery of skeletal malocclusion patients, we have tried to add many ideas to traditional treatment methods, but it was difficult to obtain satisfactory results.

In the course of many anxieties to find the cause of the limitation, the dentists have a three-dimensional form, treating the face bone of a dynamic person in a three-dimensional space, I was too dependent on static cephalograms to think about the diagnosis and treatment.

Also, considering that the change of the position of the skeleton by the operation is made by the rotation transformation and the linear transformation in the three dimensional space, it is necessary to reproduce the occlusion with the face bone in the three dimensional coordinate system. In this way, the state of the occlusion diagnosed with the articulator separated from the face can be reproduced together with the skeleton on the 3 - dimensional position, so that more accurate diagnosis and treatment will be possible.

For example, the orthognathic surgery system aims to reproduce pre-operative, post-operative, and post-operative conditions. To do so, it is necessary to digitize the patient's diagnostic data, Unlike the procedure, digital chin correction is stored as a STL (standard tessellation language) extension with cone beam computerized tomography (CBCT) for the digitized data of the patient's face, skeleton and dental state, and processed through a computer program. The stl extension is one of the international standard formats for representing three-dimensional data. It is a kind of polygon format that expresses the surface of the solid object, that is, the three-dimensional shape, composed of numerous triangular surfaces, Information,

I am using a lot of CT photographs for chin correction surgery. However, the problem is that CT photographs do not have a 3D reference plane. If there is a three-dimensional reference plane, the upper and lower mandibles can be cut, shifted and rotated at will. Before and after the treatment, the accuracy of the operation can be evaluated according to the reference plane. It is very easy to use the Boolean function, which can fill in the missing part or collapse part. This makes mock surgeries and surgical wafers much easier.

For this reason, there is a need to develop a technology capable of providing a three-dimensional plane that can be used as a reference on a CT photograph based on 3D technology.

For example, it is difficult to accurately position an object in the cyber 3D space of a CAD program. Since the Camper's plane is parallel to the occlusal plane with the same inclination, Camper's plane is used as a reference plane for five templates , It is possible to simulate the tooth movement by positioning the lower third, lower third, and lower third, respectively. Therefore, it is possible to simulate the movement of the tooth in the camper's plane, This is because the virtual teeth can be set up and moved according to this template after positioning the most suitable one.

More specifically, a method of moving and setting up a virtual tooth according to a template will be described.

First, the tooth model STL file and the CT DICOM file should be merged by using the CT image forming ball common to the two images as the medium. In order to do this, the model STL file and the CT photograph STL file must be calibrated A template is needed.

However, since the distance and the angle of the CT image forming ball of the face frame for forming a three-dimensional reference plane on the CT image of the present invention are measured, this distance is compared with the measured distance on the program, and the distance on the program is rescaled (The reduced size can be restored to its original state). As a result, when the size of the CT photograph is enlarged or reduced to the same size as the model, the two are perfectly matched.

Therefore, when the DICOM, which is the image of the CBCT, which is a three-dimensional diagnostic image formed using the face frame for forming a three-dimensional reference plane on the CT image of the present invention, and the STLfile obtained through the scan and CAD are overlapped, The information of the bone can be seen at the same time, and the tooth can be placed in the most ideal position based on the position of the bone.

Further, according to the 3D diagnostic image formed using the face frame for forming a three-dimensional reference plane on the CT image of the present invention, the result of the virtual procedure can be extracted in the form of a file in which an ideal tooth arrangement is possible in Dental CAD, In other CT viewers known so far, the result of a virtual procedure that can be seen only by itself can be realized.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various changes and modifications will be possible.
