Description

{System For Rendering 3D Data}

The present invention relates to a CT-based 3D data generation system for dental medical care, and more particularly, to a system and method for acquiring the present state of a patient's teeth 3D data based on CT for dental medical treatment, thereby improving the accuracy and convenience of a dental orthodontic appliance design such as a prosthesis and an implant And more particularly, to a CT-based 3D data generation system for a dental medical treatment.

As the aging population increases and accelerates, the dental medical orthodontic market continues to grow in recognition of the importance of oral hygiene, and the importance of design and design of orthodontic appliances for dental correction through dental orthodontics such as prostheses and implants It is getting higher.

Conventionally, a method of acquiring the impression of a patient's teeth and scanning the same with a scanner to acquire 3D tooth data of a patient's current state is widely used for designing and designing a dental correction apparatus such as a prosthesis.

However, since the conventional 3D data acquisition method must include a process of acquiring an impression from a patient's teeth, the data acquisition process is very troublesome.

In order to solve the above-described problems, a 3D scanner has been developed.

The 3D scanner has the advantage of acquiring 3D tooth data by scanning the inside of the patient's teeth without any process of impression acquisition due to development of the scanner technology. However, the 3D scanner has a limitation that an error or an error may occur in the 3D data depending on an angle or direction of scanning, and therefore, an expert must scan the 3D data.

In addition, since it is only possible to acquire 3D data based on the appearance of the teeth and the shape of the gums, there is a problem that it is difficult to acquire data necessary for the treatment of the bonding relationship of the teeth and the gums and the internal structure of the teeth. Therefore, There was a problem that could occur.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems described above and to provide a method and apparatus for acquiring 3D tooth data on the basis of a dental CT for improving accuracy of data acquisition, Roots, and the like, and to provide a CT-based 3D data generation system for a dental medical treatment that can be used for designing and designing a dental-orthodontic appliance.

According to another aspect of the present invention, there is provided a CT-based 3D data generation system for dental use, comprising: a CT management unit for registering and managing a dental CT for a patient; and a controller for generating 3D tooth data from the CT of the patient registered in the CT management unit A data processing unit for providing a 3D data generating unit and an interface capable of simulating and processing and modifying the generated 3D data and a database for storing the generated 3D data, And extracting and generating.

In the present invention, 3D tooth data generated on the basis of CT can secure dimensional accuracy and provide 3D data mapped with CT rather than providing only simple 3D outline data. Therefore, Which is useful for designing and designing, and has an excellent effect of improving the precision and accuracy of the design and design of teeth and orthodontic appliances.

The 3D tooth data generated by the CT based on the above can be used for 3D design of a precise tooth. Since the dental prosthesis can be manufactured through the precision machining by the automatic milling machine, the time required for manufacturing the dental prosthesis can be dramatically improved And the inline process produces excellent effects that can be customized to make a dental prosthesis.

FIG. 2 is a schematic view illustrating a process of generating 3D data according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is a system configuration diagram schematically showing a CT-based 3D data generation system for dental treatment according to a preferred embodiment of the present invention.

1, a 3D data generation system according to the present invention includes a CT management unit for registering and managing a dental CT for a patient, a 3D data generation unit for generating 3D tooth data from a CT of a patient registered in the CT management unit, A data processing unit for providing an interface for simulating, processing and modifying the generated 3D data, and a database for storing the generated 3D data.

The CT management unit can acquire and manage the directly photographed CT, but can be acquired and registered and managed in association with the database in which the photographed CT is stored.

The CT management unit may map the CT and the patient information corresponding thereto to be managed.

The 3D data generation unit includes a preprocessing module for extracting CT registered through the CT management unit and pre-processing the CT, a data generation module for generating 3D tooth data by rendering the shapes of the teeth and gums of the pretreated CT, And a data management module for converting the generated 3D tooth data into a predetermined format and managing the converted 3D tooth data.

The preprocessing module removes unnecessary information from the photographed CT to generate 3D data, processes the CT, and sets a composition for optimizing 3D data generation.

As shown in FIG. 2, the data generation module extracts a line of a tooth and a gum line from the preprocessed CT, and renders it into a three-dimensional shape to generate 3D tooth data.

Since the CT includes internal information such as the structure of the teeth and the tissue, the axis and the angle of the teeth can be confirmed. The internal information, the contour line of the teeth and the shape of the gum line are analyzed and rendered to generate accurate 3D tooth data can do.

Here, in order to ensure the accuracy of the 3D tooth data, it is possible to generate the 3D tooth data by fusing together the teeth photographs of the patient.

The data management module can convert the generated 3D tooth data into a set format and generalize it, and can verify whether the generated 3D tooth data and the actual tooth data of the patient coincide with each other.

To this end, the data management module may verify the data by mapping the generated 3D tooth data to the CT of the patient to check whether the tooth axis, angle, gum line, etc. match the 3D tooth data, It is possible to notify the data generation module thereof and to regenerate the data.

Meanwhile, the data processing unit provides an interface for simulating, correcting, and processing the generated 3D tooth data, and plays a role of being utilized as a program for designing a tooth correcting mechanism such as a prosthesis.

As described above, the 3D tooth data generated based on the CT can secure dimensional accuracy, and not only the 3D outline data of the teeth is provided, but also the 3D data mapped with the CT is provided. Therefore, It can be applied to design and design, and the precision and accuracy of the design and design of the tooth and orthodontic appliance can be improved.

The 3D tooth data generated by the CT based on the above can be used for 3D design of a precise tooth. Since the dental prosthesis can be manufactured through the precision machining by the automatic milling machine, the time required for manufacturing the dental prosthesis can be dramatically improved It is possible to make customized dental prosthesis through inline process.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
