The scanner 120 scans an object of the scan area SA into two-dimensional or three-dimensional image data and inputs the scanned image data. The scanner 120 may include a three-dimensional scanner or a three-dimensional photographing camera. The scanner 120 may include a two-dimensional scanner. In this case, the scanner 120 may further include an apparatus for converting two-dimensional image data into three-dimensional image data.

The tooth model 10 is scanned by the scanner 120 in combination with the jig 20 to which the object 30 is attached. The jig 20 includes a first jig 21, which is a jig for topical use, and a second jig 22, which is a mandible jig. In addition, an auxiliary jig 23 for scaling the tooth model of the scanned image data is provided.

The apparatus 1 for dental model occlusion is provided with an auxiliary jig 23 on a mounting portion 121 of a scanner 120 and a tooth model 10 and a first jig 21 or a second jig 23, (22), and then the tooth model is scanned through the scanner (120).

In the case of extracting the object information for the automatic occlusion, the first and second jigs 21 and 22 may be installed in the articulator 40 and then scanned to extract the object information. The articulator 40 is also installed on the upper side of the auxiliary jig 23.

The object 30 is attached to the jig 20. Different types of objects are attached to the first jig 21 as a top jig and the second jig 22 as a mandatory jig. At this time, the object may be a target or an object of a specific shape. An object may be attached to the auxiliary jig 23 or the articulator 40 as the case may be.

For example, when the target is used as the object 30, the first target 31 is attached to the first jig and the second target 32 is attached to the second jig.

In the data part 170, control data for operation of the device for automatic tooth-modeling of the teeth and data for automatic occlusion are stored.

Information for recognizing the object 30 attached to the jig 20 is stored as the object data 172 in the data unit 170 when the tooth model is scanned and the image for the tooth model input through the scanner 120 Data 171 is stored and the occlusion data 173 automatically interlocked by the automatic occlusion unit 140 is stored.

The control unit 110 controls the overall operation of the device 1 for dental model locking and stores the image data 171 input from the scanner 120 in the data unit 170, Thereby outputting the image data to the screen. The control unit 110 stores the data generated from the object analyzing unit 130 and the automatic bite unit 140 in the data unit 170, respectively.

The object analyzing unit 130 extracts the object from the image data 171 input from the scanner 120 and recognizes the object.

The object analyzing unit 130 extracts an object from the image data input from the scanner 120 and compares the extracted object data with the object data 172 stored in the data unit 170 to determine whether the object is a previously stored object.

The object analyzing unit 130 recognizes the object and calls the object information for the object from the object data 172. Based on the object information, the object analyzing unit 130 extracts the tooth model for the upper and lower limbs according to the shape, .

That is, the object analyzing unit 130 may include a first object 31 and a second object 32, which are different from each other in the first jig 21 as a top jig and the second jig 22 as a mandatory jig, Recognizes each object, calls object information, and applies the object information to the automatic occlusion unit 140.

When the first target 31 or the second target 32 is recognized from the first jig 21 or the second jig 22, the object analyzing unit 130 determines the positional relationship between the first target and the second target And applies the data to the automatic occlusion unit 140.

The object analyzing unit 130 can recognize the object even when the position or direction of the jig is changed when the tooth model 10 is scanned by the scanner 120 together with the jig 20. [

The automatic occlusion unit 140 receives image data for the tooth model from the scanner, and performs image processing on the image data to occlude the tooth model.

The automatic occlusion unit 140 receives image data of the maxillary teeth model and the mandibular tooth model, respectively.

The automatic occlusion unit 140 distinguishes the image data of the maxillary and mandibular tooth models based on the object information, and sets the position information of the tooth model according to the shape, position, and orientation of the object based on the object information.

Further, the automatic occlusion unit 140 matches the image data obtained by scanning the top-and-bottom tooth model and the mandible tooth model according to the positional relationship between the first target and the second target based on the object information, And the mandibular tooth model are aligned so as to be vertically aligned. Accordingly, the automatic occlusion unit 140 generates occlusion information combined with the maxilla and mandible.

For example, the automatic occlusion unit 140 determines whether the image data of the scanned tooth model is rotated to the left or right based on the object information of the tooth model, sets the position information of the image data of the tooth model, Position.

Also, even if the maxillary tooth model and the mandibular tooth model are scanned at different positions or in different directions, they can be matched based on the positional relationship between the objects.

The control unit 110 stores the occlusion information in the data unit 170 as the occlusion data 173 and displays the occlusion data on the screen through the output unit 160. [

At this time, the occlusion data includes information on the occlusal plane as well as information on the shape in which the maxillary and mandibular tooth models are combined.

The control unit 110 outputs the occlusion process through the output unit 160 and outputs the occlusion data generated by the automatic occlusion unit 140 to the screen. In addition, the controller 110 may transmit the occlusion data to the outside according to the setting. Also, the controller 110 determines an error occurring during operation and outputs an error through the output unit 160.

On the other hand, the object information for the automatic occlusion can be obtained by scanning the jig 20, and is stored in the object data 172.

When the jig 20 is scanned by the scanner 120, the object analyzing unit 130 extracts the object attached to the jig. The first target 31 of the first jig 21 and the second target 32 of the second jig 22 as the mandibular jig are divided into a first target and a second target, Lt; / RTI >

The object analyzer 130 extracts the first target 31 and the second target 32 from the first jig 21 and the second jig 22 when the first jig 21 and the second jig 22 are scanned in the state where the first jig 21 and the second jig 22 are installed on the articulator 40, And generates a positional relationship between the first target and the second target, that is, a positional relationship between the two objects. At this time, it is stored as position relation object information between objects.

The positional relationship between the objects means that the position of each object is not always the exact position in the state where the teeth models of the maxillary and mandibular teeth are meshed with each other. Therefore, even if the tooth model is scanned at a different position And is corrected through the object information to enable the occlusion.

The control unit 110 stores the object information generated from the object analysis unit in the data unit 170 as the object data 172.

When the information about the object attached to the jig is initially stored in the object data 172, as described above, when the tooth model is scanned, the object attached to the jig can be recognized and position information on the image data of the tooth model can be set do.

The control unit 110 executes the object registration mode according to the setting of the input unit 150. When the object analyzing unit 130 extracts the object from the image data scanned in the object registration mode and the object information is generated, Register.

When the jig or the object is changed, the control unit 110 can register a new object through new registration or information change.

Figs. 3 to 5 are views showing the configuration of a jig of the apparatus for occlusion of a tooth model according to the present invention. Fig.

The jig 20 includes a first jig 21 as a jig for topical use and a second jig 22 as a mandibular jig. Further, an auxiliary jig 23 for positional correction may be provided.

As described above, the object 30 may be a target or an object having a specific shape. The object is described on the basis of being attached to the jig, but in the case of the target, it can be engraved or printed on the jig.

3, the first and second jigs 21 and 22 are provided with teeth models on the upper surfaces 21a and 22a and side surfaces 21e and 22e with attachment surfaces (21b) and (22b).

Objects of a specific shape are attached to the attachment surfaces 21b and 22b, and objects of different types are attached to the first jig and the second jig, respectively. When a target is used as an object, a first target 31 and a second target 32 are attached to respective jigs.

The auxiliary jig 23 or the articulator 40 may be attached to the auxiliary jig 23 or the articulator 40. In this case,

The first jig 21 and the second jig 22 are fixed to the upper surfaces 21a and 22a of the tooth model 10 so that the tooth model 10 is always installed at the same position. (Not shown).

The tooth model coupling portion may be configured to prevent the position of the tooth model 10 from being changed during the scan, and to fix the tooth model so that the tooth model is not detached from the jig as the case may be. For example, the tooth model joining portion may be formed with a groove to insert a part of the tooth model on one surface of the jig 20, or may be configured to receive or fix a part of the teeth model protruding from the jig.

On the other hand, when the jig 20 is not provided with the tooth model coupling portion, the position for the tooth model can be displayed so that the tooth model is always installed at the same position.

4, the first jig 21 and the second jig 22 are attached to the back surface 21c, 22c by being installed or inserted into the articulator 40, the mounting portion 121 of the scanner, or the auxiliary jig, Jig engaging portions 21d and 22d are provided.

The jig engaging portions 21d and 22d may be formed with protrusions protruding from the back surfaces 21c and 22c of the jig. The jig coupling portion has at least one projection, preferably three or more projections, and the shape of the projection is hemispherical. However, the projection may be formed in a polygonal shape or in various shapes, and is not limited to the drawings.

The jig engaging portions 21d and 22d are inserted and fixed in the grooves provided in the articulator 40, the mounting portion 121 of the scanner, or the auxiliary jig as described above.

At this time, the jig engaging portions 21d and 22d are installed at predetermined positions in the scan area SA of the scanner 120 according to the number or shape of the protrusions so that the tooth model can be scanned. However, in this case, the position can be corrected by using the object.

Further, since the jig is provided at the designated position by the jig engaging portions 21d and 22d, the jig is fixed without shaking during scanning, so that the scale of the predetermined image data can be maintained and more accurate data can be confirmed.

5, the auxiliary jig 23 is additionally attached to the first or second jig 21 with the tooth model 10 mounted on the first jig 21 or the second jig 22 .

The auxiliary jig 23 is provided with a coupling portion 23b for coupling with the first jig or the second jig on the upper surface 23a. At this time, the engaging portion 23b is configured to correspond to the shape of the jig engaging portion so that the jig engaging portions 21d and 22d are inserted and fixed.

The back surface 23c of the auxiliary jig 23 is provided with fixing portions 23d, 23e, 23f for fixing the scanner to the scanner. Each of the fixing portions is configured to be inserted or fastened according to its shape. The auxiliary jig is set so as to be directly mounted on the installation part 121 of the scanner, but may be provided in various sizes and shapes depending on the application.

An articulator 40 is mounted on the upper surface of the auxiliary jig 23, or the jig 20 is mounted without the articulator.

In some cases, the first or second jig may be installed in the scanner without the auxiliary jig, but the auxiliary jig is mounted for the scale and height correction of the tooth model of the image data. When the jig and the tooth model are scanned at left and right positions, there is no influence on the automatic occlusion, but when the scan position and the height are different, the size and the angle of the tooth model on the image data are different, Because of the problem of elaborate occlusion, an auxiliary jig is used to generate a constant scale of image data. For example, when the size of image data of the maxillary tooth model and the mandibular tooth model are different, accurate occlusion data can not be obtained even when the teeth are automatically interlocked.

Fig. 6 is an exemplary diagram referred to explain an object attached to a jig.

As shown in Fig. 6, the jig 20 is provided with an object 30. [ The object 30 is used to distinguish the jig and correct the position of the tooth model mounted on the jig. The object 30 is attached to the side surface of the jig as described above, and may be printed or engraved on the jig in some cases.

The object 30 may be a target or an object. The object 30 is configured to distinguish the up, down, left, and right.

The target may be formed of a combination of points, lines, and planes, and may have a shape or pattern of a figure such as a circle, a rectangle, etc., and an image having a specific meaning may be used.

In addition, since the objects 30 are for mutual distinction, the objects provided in the first jig and the second jig, for example, the first target and the second target are configured in different forms, It is preferable that it is provided on the side surface.

7 and 8 are views showing an example of a jig installed in an articulator and an articulator of a device for tooth model occlusion of the present invention.

As shown in Figs. 7 and 8, the articulator 40 is provided with mounting portions 40a and 40b, respectively, to which the first jig and the second jig are mounted. The mounting portions 40a and 40b are formed with a groove 40c in which a jig coupling portion is inserted. A separate fixing part (not shown) may be provided on the articulator to fix the first jig without detaching it.

At this time, the device for tooth model occlusion extracts object information by scanning with the jig mounted without a tooth model.

The articulator 40 is initially used to store the positional relationship between the first target 31 as an object of the first jig 21 and the second target 32 as an object of the second jig 22 as object information . When scanning is performed with the first jig and the second jig installed in the articulator 40, the information of the first target and the second target may be extracted together to generate the positional relationship of the objects in the combined state.

When the tooth model is occluded, the tooth model 10 mounted on the jig 20 is scanned without the articulator 40, and the mutual positional relationship is determined based on the stored object information to automatically perform the occlusion.

That is, since only the jig is used at the time of the tooth model scan, the object information of the jig is recognized from the image data, the object information is called, and the respective object information about the tooth model of the maxilla and mandible is extracted from the extracted position Based on the information based on the relationship, the tooth model can be occluded without an articulator.

9 to 12 are diagrams for explaining object information generation for automatic tooth model correction of the tooth model occlusion apparatus of the present invention.

As shown in Fig. 10, the jigs 20, 21 and 22 are mounted on the upper part of the auxiliary jig 23. In order to generate object information, only a jig is mounted without a tooth model and scanned to extract an object from image data to generate object information.

Thus, the scanner 120 scans the first jig 21 and the second jig 22, respectively. The first jig 21 is provided with a first target 31 and the second jig is provided with a second target.

The object analyzing unit 130 analyzes the image data of the first jig to extract a first target attached to the first jig and analyzes the image data of the second jig to obtain a second target attached to the second jig .

The object analyzer 130 generates object information for the first target and the second target, respectively, and applies the generated object information to the controller 110. The control unit 110 stores the generated object information as object data.

The object information includes the shape, position, and jig information of the object. Since different types of objects are attached to the jig, it is possible to distinguish between a jig for a topical use or a jig for a mandible through object information. In addition, since the object is configured to be able to distinguish between up, down, left, and right, the object can be recognized and the position where the jig is mounted and the direction in which the jig is mounted can be determined.

11, the scanner 120 scans a state where the first jig 21 and the second jig are coupled to the articulator 40. In this case,

The object analyzing unit 130 analyzes the scanned image data in a state where the first jig 21 and the second jig 22 are mounted on the articulator 40 to extract the first target and the second target, 1 object and the second target are analyzed to generate object information.

Thereby, object information for each of the first target and the second target attached to the first jig and the second jig, and object information in a state where the first jig and the second jig are coupled to the articulator are generated.

 The object analyzer 130 scans the jig and acquires tag information of the jig before scanning the tooth model.

The scanner 120 scans the first jig, which is a jig for topological exploitation (S310).

The object analyzing unit 130 extracts a first tag attached to the first jig from the scanned image data, and generates tag information of the first tag (S320).

The automatic occlusion unit 140 generates data of the aligned tooth model as occlusion data (S480). The control unit stores the occlusion data and outputs the data through the output unit (S490).

Therefore, according to the present invention, the maxillary and mandibular tooth models are individually scanned and then automatically engaged based on the object information obtained through the jig scan.

Further, by eliminating interference factors through model correction and creating a final tooth model, more precise diagnosis can be made on the tooth condition and a tooth model suitable for each person can be created.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.
