Various embodiments of the present invention will now be described with reference to the accompanying drawings.

FIG. 1 shows an example of a scanning image in which a dental caries region of a carious tooth can be determined.

Referring to FIG. 1, the dental caries region of a carious tooth can be determined as to whether or not the dental caries are present due to differences in contrast between images obtained through scanning, as shown in the drawing. Conventionally, in the scanning image, the presence of the caries or the judgment of the caries area becomes a subject of the person, and there may be a difference in the judgment of the caries area according to the difference of the experience or the proficiency of the judgment subject.

In this regard, according to the recent development of scanning devices, it is possible to determine the accurate dental area through a scanning image having a high resolution. According to an embodiment of the present invention, Determine the presence or the dentition area, and obtain data on the three-dimensional tooth image and the dental caries area of the tooth. This will be described in detail later with reference to FIG. 2 to FIG.

2 shows a schematic configuration of an apparatus for manufacturing a dental restoration according to an embodiment of the present invention.

Referring to FIG. 2, an apparatus 200 for manufacturing a dental restoration according to an exemplary embodiment of the present invention includes a controller 210, a scanner 220, and a manufacturing unit 230.

The control unit 210, the scanner 220, and the manufacturing unit 230 may each be constituted by one or more devices, and the dental restoration manufacturing apparatus 200 may also be constituted by a system including one or more devices And various modifications may be made without departing from the scope of the present invention.

The control unit 210 can generate information such as a removal area map and a restoration shape map, which will be described later, by performing an operation such as executing a program or a set of instructions stored in the memory based on the information acquired through the scanner 220 And may include at least one processor and memory for this purpose. The memory may store programs, instruction sets, and the like, and may include random access memory (RAM), read-only memory (ROM), magnetic disk devices, optical disk devices, . In addition, the control unit 210 may be configured to include a database utilizing the above-described memory.

The scanner 220 acquires the shape information of the carious tooth and acquires the three-dimensional tooth image and the cariostat area map, which will be described later, by the scanner 220 and transmitted to the control unit 210, The three-dimensional tooth image and the dental caries region map may be obtained by the calculation of the control unit 210 based on the shape information.

The manufacturing unit 230 is configured to generate a restoration based on the data received from the control unit 210 and may be a variety of processing devices such as a milling unit and a rapid prototyping device, The present invention is not limited to any specific apparatus as long as it is a configured apparatus.

The roles of the control unit 210, the scanner 220, and the production unit 230 will be described later in detail with reference to FIGS. 3 to 8. FIG.

FIG. 3 is a schematic flowchart of a method of manufacturing a dental restoration according to an embodiment of the present invention, and FIGS. 4A and 4B illustrate an embodiment of a method of manufacturing a dental restoration according to an embodiment of the present invention. Will be described with reference to Fig. 2 for convenience of explanation.

2 through 4, a method of manufacturing a dental restoration 450 according to an embodiment of the present invention includes first scanning 405 a dental tooth 400 through a scanner 220, The tooth image 420 and the dental caries area map 410 are acquired (S300).

The dental tooth 400 is a dental restoration 450 according to an embodiment of the present invention. The dental restoration 400 includes teeth, such as enamel caries, dental caries, and cemented caries, This applicable dental caries tooth 400 includes all the dental teeth which are damaged by the above-described caries or for which restoration treatment is required for other reasons.

The three-dimensional tooth image 420 represents three-dimensional information representing the entire image of the tooth including the dental area 401 of the dental carousel 400. The dental caries area diagram 410 also indicates the dental caries area 401, Dimensional information indicating the dentition area 401 so as to distinguish the width, height, and the like of the dentition area 401, not whether or not the denture area 401 exists.

The scanner 220 performing the scanning 405 of the dental caries 400 is preferably configured to be capable of three-dimensional scanning to obtain a three-dimensional tooth image 420 and a dental caries area 410, And may be configured to acquire three-dimensional information through two-dimensional scanning in various directions. For example, in the case of CBCT (Cone beam computed tomography), which is widely deployed, recent advances have been made in terms of resolution, thereby obtaining a high-quality image using a small dose of radiation and reconstructing it three-dimensionally In the case of optical coherence tomography (OCT), it is possible to acquire three-dimensional information on the principle similar to CBCT without the radiation exposure problem in the case of relatively shallow caries not invading to the dentin. In addition, it is possible to acquire the three-dimensional tooth image 420 and the dental caries area diagram 410 by utilizing various types of dental caries discrimination devices such as a laser.

When the three-dimensional tooth image 420 and the dental caries area map 410 are acquired, the control unit 210 generates the removal area map 430 based on the three-dimensional tooth image 420 and the dental caries area map 410 (S310).

The removal area map 430 refers to three-dimensional information indicating an area to be removed including the dental area 401 of the dental caries 400. The treatment of the caries tooth 400 is generally performed by deleting a region larger than the caries region 401 to reliably remove the caries tooth or caries lesion, and the larger the area of the tooth to be deleted in the treatment of the caries tooth 400, It is desirable to remove the minimum area within the range of reliably removing the caries tooth or caries lesion since the healthy tooth is weakened. The removal area map 430 generated by the control unit 210 is a map of the area 3 that can reliably remove the caries tooth or caries lesion based on the three-dimensional tooth image 420 and the dental caries area map 410 Dimensional information.

A detailed description of the removal area map 430 will be described later with reference to FIG.

According to an embodiment of the present invention, the process of creating or acquiring the removal area map 430, the restoration form diagram 440 and the removal method, which will be described later, can be performed through a predetermined process, , Matching with a previously stored database, or detecting or calculating information through a pre-stored program or set of instructions.

For example, the three-dimensional tooth image 420 and the dental caries area map 410 are matched with the database in which the data of the dental caries and the treatment are stored, to detect similar data, Removal method, and restoration form diagram based on the three-dimensional tooth image 420 and the carious area diagram 410 through a program or a set of instructions generated through the accumulated data .

The control unit 210 generates the restoration form figure 440 based on the three-dimensional tooth image 420 and the removal area figure 430 when the removal area figure 430 is generated at step S320.

When the area to be removed including the dental caries area 401 of the carious tooth is deleted, since the shape of the restoration can be changed according to the area of the residual healthy tooth, the removal area map 430 as well as the three- Based on this, a restoration form figure 440 is generated. For example, the shape of the restoration, such as an inlay, an onlay, or a crown, may vary depending on the proportion of the residual healed area compared to the residual healthy hothouse, not just the restoration that matches the area to be removed , And the restoration shape 450 reflecting the restoration shape 440.

A detailed description of the design of the restoration form will be given later in FIG.

The method of manufacturing a dental restoration according to an embodiment of the present invention determines the shape of the restoration in advance in the diagnosis step of the dental area based on the area to be removed from the dental caries through the above- The preparation of the restoration can be started at the same time, or concurrently, with the restoration, or before the ablation of the abdominal area is substantially performed. In addition, it is not necessary to perform the process of impression taking during the course of tooth preparation, impression preparation, model making and restoration, which is a treatment process of a general dental tooth, and it is necessary to prepare the restoration in parallel with the dental erasure process, Thereby saving time.

In order to produce such a restoration, consistency and objectivity are required for the dental caries area of the carious tooth to be precisely removed according to the removal area described above. The objectivity of such treatment will be described later in detail with reference to FIG. 5 to FIG.

FIG. 5A illustrates an embodiment of creating an elimination area map according to an embodiment of the present invention, and FIGS. 5B and 5C illustrate an embodiment of generating a restoration shape diagram according to an embodiment of the present invention .

5A, in determining the removal region for the toothous area 401 of the tooth, consideration is given to whether or not the tooth has nerve damage, the thickness and position of the residual healthy tooth after removal of the caries area, If the removal area is determined to be narrower than the denture area 401, the dental caries or caries lesion can not be reliably removed. If the removal area is determined to be wider than the denture area 401, It can remove the healthy hemorrhoids, and the remaining healthy hemorrhoids can be relatively weakened. For this reason, the removed region should be determined as the minimum area 501 in which the caries tooth or caries lesion can be reliably removed. According to an embodiment of the present invention, the controller 210 described above with reference to FIG. Based on the image and dental caries area map, we generate an elimination map corresponding to the three-dimensional information on the minimum area that can reliably remove the caries tooth or caries lesion.

As can be seen in FIGS. 5B and 5C, the restoration shape diagrams 525 and 535 may differ depending on the type of residual healthy tooth 520, 530 when the removal area is removed according to the removal area map. More specifically, considering the strength, thickness, and position of the area to be removed, the thickness of the remaining healthy hemorrhoid is thin or weak (530), or the area of the cleansed area is wide A crown-shaped restoration shape 535 for covering and protecting the entire remaining healthy hemorrhage is generated. When the filling treatment using amalgam or resin is performed, the area to be removed is wide, In the case where there is no need to cover the entirety by the sufficient strength of the healthy hemorrhage 520, a restoration shape 525 such as an inlay or onlay is produced. According to one embodiment of the present invention, the control unit 210 described above in FIG. 2 generates a restoration shape diagram 525, 535 considering the residual healthy tooth as described above based on the three-dimensional tooth image and the removal area map .

As shown in FIG. 5, the controller 210 described above with reference to FIG. 2 determines the three-dimensional information about the minimum area that can reliably remove the caries tooth or caries lesion based on the three-dimensional tooth image and the dental caries area map , And creates a restoration shape based on the three-dimensional tooth image and the removal area map in consideration of residual residual hemorrhage, and generates a removal area map and a restoration shape map based on the three- Or a method of detecting or calculating information through a pre-stored program or set of instructions to determine the type of removal area and restoration with consistency and objectivity.
