Description

Technical Field [0001] The present invention relates to a data conversion device for artificial tooth processing,

The present invention relates to a data conversion apparatus for artificial tooth processing and an artificial tooth design method using the same.

Impression in dental prosthodontics is an important clinical process that is essential for the diagnosis of the patient, planning of the future treatment, and the production of accurate prosthesis. Typical impression methods require skilled technicians to select the appropriate impression material according to the procedure and to make accurate impressions. Repetition of the impression may be inevitable due to various factors such as impression modification due to wrong selection or use of the impression material, vomiting response of the patient irrespective of the skill of the surgeon, and open defect. In addition, even in the stage of making the gypsum model after the impression taking, it may cause errors in the production of the dental prosthesis due to the limit of the detailed reproduction of the material and the abrasion. Therefore, studies are being conducted to automate the utilization and design and production of a computer for the design and processing of a dental prosthesis that proceeds manually.

In addition, when the scan data of the patient already exists, that is, when there is at least one scan data of the maxilla or mandible on the storage device 230 or the server device 500, the scan data may be read and displayed.

In addition, since the scan data of the patient already exists and the treatment is completed among a plurality of teeth requiring treatment of the patient, the necessary prosthesis is designed, and the prosthesis is synthesized in the scan data and stored in the storage device 230 or the server device 500 If stored, the stored data may be displayed.

In addition, the oral information detection unit 1700 can enlarge and display the area to be treated, which is automatically required to be treated. If there are a plurality of areas to be treated, the oral information detection unit 1700 can list and display the list of teeth. Information that can be displayed together.

If there is a tooth in the selected area, information that can identify the tooth, such as the type of the tooth or the number of teeth, , The information may be displayed by estimating the kind of teeth and the number of teeth that should have existed in the selected area based on the kind of the adjacent teeth or the number of the teeth when the selected area does not have a tooth due to a tooth missing or the like .

The oral information detector 1700 can detect the oral information from the scan data of each of the maxilla and mandible, and the oral information can be detected by the dental structure, the angle between the teeth and the teeth, the tooth gap, And may further include tooth condition information such as tooth color, caries, tooth decay, tooth damage, and tooth defect. More specifically, it is possible to detect intrinsic characteristic information of a tooth from a three-dimensional model generated based on scan data and to detect the state information of a tooth from a two-dimensional image generated based on the scan data. The two-dimensional image and the three-dimensional model data may be data generated by the oral scanner 100 and transmitted to the data conversion apparatus 200. The data conversion apparatus 200 may receive the scan data received from the oral scanner 100 As shown in FIG.

Further, the oral information detection unit 1700 can detect the tooth area on the scan data of the upper and lower teeth. As an example of detecting a tooth area, a tooth area may be detected based on a pixel-by-pixel tone value, but the present invention is not limited thereto, and an operator may manually display a tooth area on the image through the input device 250. Then, the oral information detecting unit 1700 can store the positional information of the displayed area when the operator displays the information.

In addition, the oral-information detecting unit 1700 can detect a region to be treated on the dental area.

The area to be treated refers to a region having a color different from the color of the peripheral teeth or the color of the average teeth on the tooth region due to tooth damage such as a caries or tooth decay, or a tooth defect.

As an example of a method of detecting a region to be treated, a tooth region is divided into a plurality of regions by considering an average tooth size of each kind of tooth, and a gray value of each of a plurality of divided regions is divided into a plurality of regions, It is possible to detect a region to be treated by detecting an area having a difference greater than or equal to a predetermined value. Alternatively, the region to be treated may be detected by detecting an average gray level value of the dental area and detecting an area where a difference between the average gray level value and the gray level value equal to or larger than the predetermined value is detected. In addition, the present invention is not limited to this, and the operator may divide the dentition area of the image into a plurality of areas through the input device 250, and the mouth information detector 1700 may store the position information of the divided areas.

In addition, the oral information detection unit 1700 can enlarge and display the detected region to be treated, and further display information about the type of the tooth and the number of the tooth. In the case of a plurality of treatment target areas, a list can be displayed.

In addition, the oral information detecting unit 1700 may detect an average tone value of a region excluding the region to be treated in the dental area and provide it to a prosthesis providing unit to be described later. Based on the information, it is possible to provide a prosthesis having a color similar to the tooth color of the patient.

The embodiment of the present invention detects the area to be treated in the maxillary or mandibular scan data and enlarges and displays the detected area to be treated, so that the operator can quickly check damaged teeth due to dental caries, tooth decay and the like. In addition, when a prosthesis is provided, it is possible to provide a prosthesis having a color similar to the color of the patient's teeth, thereby improving the satisfaction of the patient's treatment.

Meanwhile, the maxillary and mandibular scan data can be scanned at once by the oral scanner 100 including the omnidirectional lens.

The oral scanner 100 includes a lens array having at least one lens capable of receiving a 360 degree omni-directional image with a specific angle of view according to the refractive index and capable of improving the efficiency of light received from the omnidirectional lens, And an image sensor for detecting and converting one light into a digital signal.

Since the oral scanner 100 can acquire omni-directional images, it is possible to acquire maximal or mandibular scan data by one scan. Therefore, it is possible to acquire full image of full arch and to detect the area to be treated without having separate equipment such as two-dimensional camera equipment or coloring equipment as well as scan data for the manufacture of prosthesis, thereby collecting oral information such as caries and cavity can do.

In addition, since full scan scan data can be acquired by one scan, it is possible to eliminate an error caused in matching of a plurality of scan data, acquire full scan scan data in a short period of time, The accuracy of design and fabrication of the prosthesis can be improved by using the three-dimensional tooth image of the actual patient rather than the model image generated according to the matching of the scan data.

On the other hand, the central region of the image image shown in Fig. 5 is a region where no image is received by the omnidirectional lens by the reflection plate formed in the central region of the omnidirectional lens.

Fig. 6 is a flowchart of the manufacture of a prosthesis using the data conversion apparatus.

Referring to FIG. 6, the data conversion apparatus 200 may receive at least one scan data of the maxilla or mandible from the oral scanner 100 (S100). The received scan data may be stored in the storage device 230 (S110).

Next, the data conversion apparatus 200 converts the two-dimensional image into a panoramic image using the received scan data, displays the converted data, and displays the converted three-dimensional model (S200). The panoramic image and the three-dimensional model may be stored in the storage device 230 (S210). Also, the two-dimensional image herein is at least one of an image of the maxilla or mandible in the mouth of the patient. And the three-dimensional model may be the same as at least one of the maxilla or mandible in the patient's mouth. That is, the three-dimensional model converts the patient's oral structure into a three-dimensional graphic model.

In addition, the oral information detection unit 1700 can detect the intrinsic characteristic information of the teeth related to the dental structure such as the tooth size, the angle between the teeth, and the tooth interval based on the two-dimensional image of the scan data (S300). The two-dimensional image based on the scan data can be a two-dimensional image captured by the oral scanner 100. The data conversion apparatus 200 receives the scan data formed by the scan of the oral scanner 100, Dimensional image generated from the scan data. In addition, the dental structure information is used to detect the dentition on the two-dimensional image through the image processing, to detect the position information of each of the plurality of teeth in the detected dentition, to calculate the angle and interval information, And may be information generated as information is detected. In addition, the oral information detection unit 1700 may match the unique characteristic information of the teeth with the information identifying the corresponding patient (S310).

Next, the oral information detection unit 1700 can detect a region to be treated based on the state information of the teeth through image processing based on image analysis (S400). In step S400, the operator may designate the area to be treated by looking at the screen directly displayed. Then, the oral information detection unit 1700 may store information about the region to be treated with information identifying the corresponding patient (S410). In addition, the treatment target areas can be listed and stored in order of priority. The priority here is the degree to which the injured area is so large that it can be an order of priority for treatment.

In addition, the history of the patient can be managed by reading the information about the medical treatment area or the medical treatment area stored at the time of the treatment (S420).

Next, the oral information detection unit 1700 extracts the detected region to be treated from the images of the maxilla or mandible and can independently display it. If there is a plurality of regions to be treated, the oral information detection unit 1700 can list and display the list. In addition, the treatment target area may be listed and displayed in order of priority, and the priority of the treatment area may be the order of the treatment area to be preferentially treated because the damaged area is largely detected.

Next, a three-dimensional model of the abdomen or gum on the area to be treated can be generated (S600). For example, if a tooth exists on a region to be treated, the tooth preparation is prepared and the tooth prepared by the oral scanner 100 is scanned to generate scan data, and the data conversion apparatus 200 (S600). Here, the preparation means that a part of the tooth is removed before the prosthesis is applied. Therefore, since the shape of the tooth has changed since the preparation, re-scanning is performed. However, the preparation may be omitted if there is no tooth in the area to be treated, or the rescan process may not be performed if the scan data is used. When the abutment is installed in the treatment target region for the implant treatment, the data conversion apparatus 200 transmits the scan data of the abutment or the scan data of the prepared abutment prepared for the abutment to the oral scanner 100).

Next, a three-dimensional model can be generated using the generated scan date by re-scanning the region to be treated (S700).

The prosthesis type can be selected based on the generated three-dimensional model (S800). In this case, the operator can select an appropriate one from the plural prosthesis list, and the region where the three-dimensional model after the preparation is located in the three-dimensional model of the preparation front is detected, The prosthesis can be listed and displayed, or any one of the prostheses can be automatically selected and displayed.

Next, a region to design the prosthesis on the generated three-dimensional model can be selected (S900). Also, the area to be designed for the prosthesis can be extracted by trimming the three-dimensional model.

The prosthesis can then be designed according to the selected prosthesis type (S1000).

The data of the prosthesis designed next can be transferred to an artificial tooth processing apparatus to produce a prosthesis (S1100).

7 is a detailed flowchart of the prosthesis design.

Referring to FIG. 7, in step S910, the operator can trim and process the three-dimensional model generated in step S900 by designating the area through the input device 250, thereby extracting only the required area from the three-dimensional model. Alternatively, the data conversion apparatus 200 may detect the position of the three-dimensional model after preparation on the three-dimensional model of the prep table by comparing the three-dimensional model of the prep table in step S100 and the three-dimensional model after the preparation in step S600 And the three-dimensional model may be automatically trimmed in step S900 by comparing the areas.

In addition, regarding the modification of the prosthesis design in step S1000, the design modification of the prosthesis may include adjusting the angle, size, shape thickness, and position of the prosthesis.

The next designed prosthesis data may be stored in at least one of the storage device 230 and the server device 500 (S1010).

The next designed prosthesis is image-synthesized into a two-dimensional image in which a treatment target area exists and a treatment target area in a three-dimensional model, and the existing scan data is updated and stored in at least one of the storage device 230 and the server device 500 (S1020). When the history information of the patient is displayed, the image information of the treated state is displayed so that the treated matters can be updated on the image. Also, when the treatment target areas are listed and displayed in step S500, only the remaining treatment target areas other than the treatment target areas already treated may be listed and displayed.

8A is a detailed flow chart of the selection of the prosthesis type.

Referring to FIG. 8A, when the prosthesis type is selected in step S800, the data conversion apparatus 200 may detect the presence or absence of a tooth on the three-dimensional model (S810).

Next, if it is detected that a tooth exists, it is possible to detect whether or not the cusp of the tooth is fully formed (S820).

Next, when the cusp of the tooth is perfect, the prosthesis can be automatically selected based on the shape information of the cusp of the tooth (S830).

When the cusp of the tooth is not perfect, the cusp information of the corresponding tooth of the tooth and the intrinsic characteristic information of the adjacent tooth are detected (S840), so that a plurality of prosthesis candidates can be automatically selected. In the case where a plurality of prosthesis candidates are automatically selected, Any one of a plurality of prosthesis candidates may be selected through the input device 250 (S850). When the prosthesis is installed on the tooth on the treatment target area, the opacity of the prosthesis can be detected by detecting the cortical information of the opposed tooth as a tooth that is occluded with the prosthesis, so that the patient wearing the prosthesis can be prevented from feeling inconvenience . Also, by automatically selecting and presenting a plurality of prosthetic candidates suitable for the patient using the cusp information of the opposed value, the operator can be provided with the help of selecting the prosthesis.

However, if the cusp of the tooth is not perfect, the cusp information of the tooth may be detected to display the cusp information (S840). And the operator can select any of a plurality of prostheses on the stored prosthetic database based on the cortex information of the displayed comparison value. Therefore, the operator can select a more appropriate prosthesis using the cusp information of the opposing teeth.

If it is detected that the tooth does not exist according to the result of the detection in step S810, it is determined based on the unique information of the tooth to be positioned on the region to be treated, the cortex information of the opposing tooth, and the size and position information of the adjacent tooth adjacent to the region to be treated The prosthesis can be automatically selected, and the prosthesis here can be an artificial tooth model that can replace a missing tooth (S860).

8B is a detailed flowchart of the selection of a prosthesis type according to another embodiment.

Referring to FIG. 8B, when selecting the prosthesis type in step S800, the data conversion apparatus 200 can identify the presence or absence of existing patient's three-dimensional model data in at least one of the storage device 230 and the server device 500 (S801). That is, if there are three-dimensional model data based on the scan data of the teeth that existed in the area to be treated in the past, the corresponding three-dimensional model data can be used as restoration data to be applied to the damaged teeth (S802). By using the same three-dimensional model data as the actual teeth of the patient, the prosthetic design process can be omitted or minimized and the most suitable prosthetic tooth can be manufactured for the patient.

If there is no existing three-dimensional model data of the tooth, the restoration design model library according to the restoration type is displayed and displayed so that the user can select any one of the restoration design models on the loaded library (S803). In this case, the prosthesis type selection process described in FIG. 8A may be applied.

Hereinafter, the method of designing the prosthesis will be described in detail.
