  In the “apparatus and method for forming a margin on a workpiece, especially a cutting tool” described in Patent Document 1, in order to form a margin, a laser unit and a clamp are arranged so as to continuously rotate the workpiece in the clamping device. Since it controls the device, it performs the same operation every time.

  In addition, in the “tire marking device, tire marking method, and tire” described in Patent Document 2, information on the tire type based on the barcode label attached to the tire is associated with the position data stored in the database. Based on this position data, the mounting table on which the tire is mounted may be controlled.

  However, all dental technicians, for example, dentures, are custom-made, so the shape differs for each wearer, and there is no one that is the same. Therefore, it is not possible to prepare position data in advance indicating the range to be marked.

When dentures with such circumstances are irradiated with laser to imprint information, it is necessary to operate the movable table with the dentures fixed to adjust the position to be imprinted toward the laser irradiation side.
For example, if the shape of the denture is slightly different, the same position may be engraved. However, when the denture is completed and replaced with the next denture, the installation location of the denture is slightly shifted. Therefore, if it is going to stamp at the same position, adjustment of the installation place of each denture is required. Since this adjustment requires accuracy, fine adjustment is complicated.

Then, the information is added to the information adding unit 130.

The 3D data generation unit 240 generates stereoscopic 3D data based on the scanning data from the scanner unit 120.
Based on the 3D data obtained by the 3D data generation unit 240, the assignment position selection unit 250 sets a range selected by the operator by operating the input unit 270 as the assignment position. Further, the application position selection unit 250 calculates the flatness of the surface of the plate denture D based on the 3D data from the 3D data generation unit 240 and selects the application position.

The verifying unit 290 has a function of verifying whether or not the information M has been correctly given to the bedded denture D to which the information M has been given.

Here, the information stamped on the denture D will be described.
The stamp can be, for example, identification information. The identification information is associated with the personal information registered in the database, so that the individual can be indirectly specified. The personal information may be a name, address, date of birth, sex, blood type, hospital name that identifies the dental clinic involved in treatment, a code identifying the hospital, and the like.

In particular, when the wearer suffers from dementia, if the information about the family to be contacted is associated, the identity of the wearer who is hesitant can be confirmed immediately, and the family can be contacted or worn. You can get in touch immediately when you get permission for treatment.
The identification information can be the wearer's name or a nickname. Furthermore, it can be a family crest, a photograph of a wearer, a figure, a picture, or the like.

Also, the information may be the name of the dental laboratory that produced the bedded denture D, the mark of the dental laboratory, identification information for identification from other dental laboratories, the model number of the denture, the identification information of the denture, etc. it can. If the information to be engraved is the identification information of the denture, and the manufacturing data on the bed denture D is made into a database in the dental laboratory, the date of manufacture of the bed denture D by the identification information of the bed denture D, It is possible to grasp the history so far, such as the material.
Furthermore, when personal information is directly given as information to be engraved on the denture D, it can be encrypted information.

  The operation and use state of the dental technician information providing apparatus 10 according to the first embodiment of the present invention configured as described above will be described with reference to the drawings. In addition, the information stamped on the denture D is assumed to be set in advance.

First, the operator sets the bed denture D on the stage 142 of the movable table 140. Then, the operator operates the input unit 270 to instruct the scan control unit 220 to start scanning.
The scan control unit 220 instructs the scanner unit 120 of the information providing apparatus 100 to perform 3D scanning via the communication units 210 and 110, and simultaneously moves the scanning position of the plate denture D workpiece toward the scanner unit 120. To instruct.

  The movable table 140 rotates the stage 142 while swinging the swing arm 141. By doing so, since the position of the denture D facing the scanner unit 120 is sequentially changed, the scanner unit 120 can sequentially 3D scan the entire surface of the denture D except for the concave portion with which the jaw ridge contacts. it can.

  Coordinates indicating the position of the contoured denture D obtained by the scanner unit 120 performing 3D scanning are output as scan data to the scan control unit 220 via the communication units 110 and 210. The scan control unit 220 stores this scan data in the storage unit 280 and notifies the 3D data generation unit 240 thereof. The 3D data generation unit 240 generates stereoscopic 3D data based on the scanning data from the scanner unit 120 read from the storage unit 280, stores the generated 3D data in the storage unit 280, and displays it on the display unit 260.

As shown in FIG. 3, the operator operates the input unit 270 while referring to the stereoscopic 3D data displayed on the display unit 260 to select the application position S to which information is added according to the range.
For example, the range can be rectangular by specifying upper left and lower right, circular by specifying the center and radius, or arbitrary shape by drawing an outline.
The giving position selection unit 250 can display the range selected by the operator as the giving position S in the 3D data displayed on the display unit 260 in a color different from the color outside the range. At this time, the grant position selection unit 250 can display the information M with the maximum size that can be given to the range defined as the grant position S, and simulate the grant state.

  When the operator operates the input unit 270 to instruct the application position selection unit 250 that selection of the application position S has been completed and also instructs the information application control unit 230 to start laser irradiation, the application position selection is performed. The unit 250 outputs the application position S selected from the 3D data to the information application control unit 230 as application position data.

The information addition control unit 230 controls the movable base 140 based on the coordinates of the application position so that the range indicated by the application position data is directed to the information addition unit 130. Further, the information addition control unit 230 reads the addition information data for imprinting the information M from the storage unit 280 and outputs it to the information addition unit 130 via the drive control unit 150.
Since the information application control unit 230 controls the movable table 140 on which the denture denture D scanned by the scanner unit 120 is disposed, the movable table 140 operates without shifting the application position of the dental technique. Therefore, the application position can be specified accurately. Accordingly, the application position can be accurately directed to the information application unit 130.

The information addition control unit 230 instructs the information addition unit 130 to irradiate laser light when the application position has moved to a position facing the information addition unit 130.
The information imparting unit 130 irradiates laser light based on the imparted information data from the information imparting control unit 230, thereby denaturing the surface of the denture denture D and imprinting information M as shown in FIG.

Next, the control device 200 verifies whether or not the information M is correctly given to the bedded denture D.
First, the operator operates the input unit 270 to instruct the scan control unit 220 to start verification. Then, as in the first scan, the scan control unit 220 instructs the scanner unit 120 to perform 3D scanning while instructing the movable stage 140 of the information providing apparatus 100.
The scan control unit 220 stores, in the storage unit 280, coordinates indicating the position of the outer shape of the bed denture D obtained by the scanner unit 120 performing 3D scanning as scan data.

The verification unit 290 compares the 3D data of the plate denture D before the information M is engraved with the 3D data of the plate denture D to which the information M is added, and the 3D data of the plate denture D to which the information M is added. Based on this comparison, the verification unit 290 determines whether or not the information M is correctly given to the bedded denture D, and displays the result on the display unit 260.
The verification unit 290 displays the two pieces of 3D data on the display unit 260, respectively, so that the operator can confirm the contents of the verification.

  Thus, even if the shape of the dental prosthesis D, which is a workpiece, is different for each wearer, the dental technical information providing device 10 performs 3D scanning in a state where the dental prosthesis D is scanned in 3D. Since the information M is added to the selected application position, the operation can be simplified and the information M can be accurately applied.

  In addition, the operator operates the input unit 270 while referring to the 3D data displayed on the display unit 260 to select the application position where the information is imprinted. By directing the work, it is possible to mark the application position selected by the operator.

Next, the function of the application position selection unit 250 that automatically selects the application position will be described.
It is assumed that the denture D has already been 3D scanned and 3D data has been generated. Further, it is assumed that the information to be given is set in the information grant control unit 230 as the grant information data. The assigned information data at this time indicates characters, symbols, figures, photographs, and pictures, and includes data indicating the size. For example, when the character string “ABC999” is given, the data indicating the font becomes the data indicating the size. Therefore, the range required for assigning a character string of 5 characters using a font based on data indicating the size is a range for obtaining flatness.
In addition, when a figure, a photograph, or a picture is added, it can be a rectangular range in which the figure is inscribed. Furthermore, an ellipse, a polygon, or an arbitrary shape in which a figure, a photograph, or a picture is inscribed can be used.

The provision position selection unit 250 obtains a range (a range for obtaining flatness) necessary for provision of information from the provision information data. Hereinafter, the range necessary for the application is referred to as a processing range because it is a range processed by laser irradiation.
Next, the application position selection unit 250 compares the required range with the 3D data and calculates the flatness within the processing range.
The flatness is calculated as follows. First, a tangent TL passing through a point P1, which is an arbitrary point on the surface of the denture D, and two points (P2, P3) located below the tangent TL and sandwiching the point P1 around the point P1. The distances L1 and L2 between the points P2 and P3 on the boundary of the machining range are calculated. Next, the point P1 is moved in a direction orthogonal to the direction from the point P2 to the point P3 within the processing range, and the distances L1 and L2 are sequentially obtained and combined over the entire processing range. If the value obtained by adding the distances L1 and L2 is small, it can be said that the flatness is high.
The application position selection unit 250 can sequentially test the machining range on the surface of the denture D, and extract some candidates from the machining range with the highest flatness.

  By setting the machining range thus obtained as the application position, the application position with the highest flatness is automatically selected. Alternatively, some candidates may be superimposed on the denture D and displayed on the display unit 260, and the operator may operate the input unit 270 to select the application position. Since the application position with high flatness can be accurately engraved with laser light, it is possible to apply information with high accuracy.

  In the first embodiment, based on the application position selected by the application position selection unit 250, the information application unit 130 applies the information M by the laser beam to the bedded denture D. When the flatness cannot be obtained, the operator may operate the input unit 270 to select the application position. In that case, the provision of the information M is formed according to the curved surface shape of the workpiece.

Next, a case will be described in which manufacturing data for producing the plate denture D is stored in the storage unit 280 of the control device 200, and information is given with reference to the manufacturing data.
Manufacturing data is data used when manufacturing the denture D1 which is a local denture, for example.
The bed denture D1 shown in FIG. 6 includes a first denture part 20 and a second denture part 30.

  In the first denture part 20, tooth artificial teeth 21 from the lower left 4th (first premolar) to the lower left 7th (second molar) are supported by a resin first denture base 22 (denture base). ing. The first denture part 20 is provided with a left side clasp 23 that hooks the lower left third (canine tooth) as an abutment tooth and stabilizes the mounting of the first denture part 20.

  In the second denture part 30, tooth artificial teeth 31 from the lower right 4th (first premolar) to the lower right 7th (second molar) are supported by a resin-made second denture base 32. . The second denture part 30 is provided with a right side clasp 33 that hooks the lower right third (canine tooth) as an abutment tooth and stabilizes the mounting of the second denture part 30.

The first denture part 20 and the second denture part 30 are connected by a bar 40.
The bar 40 is formed in an arch shape along the dental arch from the lower left third of the first denture part 20 to the lower right third of the second denture part 30.
The embedded portion 41 of the bar 40 in the first denture base 22 and the tip portions 22a and 32a of the second denture base 32 has a first portion 41a in which the thickness from the exposed portion 42 is maintained. The thickness of the bar 40 is reduced from the first portion 41a of the bar 40 embedded in the first denture base 22 and the second denture base 32, and the first denture base 22 and the second denture are formed as the second portion 41b. It extends toward the bases 22b and 32b of the floor 32, respectively. A pair of protrusions 41c for preventing the bar 40 from coming off from the first denture base 22 and the second denture base 32 is formed at the boundary between the first portion 41a and the second portion 41b.

  The first denture base 22 and the second denture base 32 are formed of a denture base-forming material in which a red-colored chemical fiber (capillary blood vessel artificial fiber) imitating a capillary is contained in a transparent acrylic resin. The denture base-forming material can be made into a translucent resin by containing capillary artificial fibers in the transparent resin.

  The production data of the bed denture D1 is obtained by associating material attribute data indicating the material of the member constituting the bed denture D1 with the 3D data indicating the bed denture D1. For example, the first denture base 22 and the second denture base 32 are made of resin, and the left side clasp 23, the right side clasp 33, and the bar 40 are made of metal. Associated with the 3D data shown. The material attribute data may be subdivided into a resin type, a metal type, or the like.

  The information addition control unit 230 superimposes 3D data obtained by 3D scanning the plate denture D1 and manufacturing data, determines from the manufacturing data what kind of material the member corresponding to the application position corresponds to, and provides information. Designates the intensity of the laser light emitted by the applying unit 130. For example, if the application position is the first denture base 22 or the second denture base 32, the information application control unit 230 suppresses the intensity of laser irradiation with resin or the like, and if the application position is the bar 40, the information application control unit 230 is made of metal. Increase the strength of By doing so, the information provision part 130 can be marked with the intensity | strength of the laser irradiation suitable for the position which provides information.

Further, the application position selection unit 250 can superimpose 3D data obtained by 3D scanning the plate denture D1 and manufacturing data, and can select an application position when the application position is selected.
