DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for efficiently producing artificial teeth (artificial teeth) such as dentures, dentures, and crowns, and a system for predicting and diagnosing symptoms in the oral cavity.

[0002]

2. Description of the Related Art FIG. 6 is a flowchart showing a conventional method for producing artificial teeth such as dentures and dentures performed by a dentist and a dental technician in cooperation. In the manufacture of a conventional artificial tooth, first, a dentist (clinic / hospital) puts a tray in the patient's mouth and molds the patient's tooth mold with agar or silicone (step 101 in FIG. 6). Next, the dentist pours gypsum into the agar mold to make a gypsum dental model (step 102). FIG. 7A shows an example of a dental model manufactured by the dentist. And
The manufactured gypsum dental model is sent to a remote dental laboratory by mail or the like (step 103). The above steps 101 to 103 are performed by the dentist.

Next, the dental laboratory uses the sent plaster dental model to create a tooth profile with wax (step 104). Next, the tooth profile of the wax is embedded in a dental investment material (gypsum or Linsan) to form a mold for artificial tooth casting (step 10).
5). Next, a metal such as gold or silver is poured into the mold to cast a metal artificial tooth (step 10).
6). Thereafter, the surface of the metal artificial tooth is polished (step 107). Then, if desired by the patient (optionally), a ceramic film close to the natural tooth color is applied to the surface of the metal artificial tooth (step 108), and the surface is further polished. It is completed (step 109). The above steps 104 to 109 are performed by a dental laboratory. 7 (b) and 7 (c) show the above-mentioned artificial teeth, in which 22 indicates an artificial tooth, and 22a indicates a hollow portion of the artificial tooth.

[0004]

In the conventional method for manufacturing an artificial tooth as described above, the following various problems have been pointed out. First, since agar is used to acquire the shape of the patient's teeth, there is a problem that a measurement error (inconsistency) is likely to occur, and the measurement of the patient's tooth profile cannot be performed with high accuracy. In addition, when measuring a patient's tooth profile with agar, the patient needs to keep his or her teeth still for at least 3 minutes until the agar solidifies, which causes great pain to the patient. In addition, the method of measuring the tooth profile of a patient with agar has a problem in that the measurement accuracy greatly varies due to a difference in the level of personal skill of a person (doctor or nurse) using the agar. Also, in the method of measuring a patient's tooth profile using agar, agar is used. There is a problem of putting a burden. In addition, the method of measuring the tooth profile of a patient using agar has a problem that it is difficult for a person who cannot go to the hospital due to, for example, being bedridden to have artificial teeth prepared.

In the conventional method of manufacturing an artificial tooth, since a dentist and a dental technician perform each work at a distance from each other, a dental model (made of plaster) manufactured by the dentist is used for postal mail or the like. Since the method has to be sent to the work place of the dental technician, the period for manufacturing the artificial tooth is prolonged, and there is a problem that the artificial tooth cannot be quickly provided to the patient.

Next, FIG. 2 is a view for explaining the measuring instrument 1. The measuring instrument 1 is inserted into an oral cavity 10 of a patient to acquire three-dimensional shape data of a specific tooth 11 of the patient. This measuring instrument 1 is a non-contact type three-dimensional shape input device, for example, scans (scans) a patient's teeth as a subject by emitting laser light, and uses the reflected light as C
The three-dimensional shape data of the teeth is input to the workstation 2 while being captured by a CD (Charge Coupled Device) and further measuring the distance to the tooth which is the subject by the principle of triangulation. The dentist inserts the measuring instrument 1 into the oral cavity of the patient and moves the measuring instrument 1 while facing the patient's teeth so that the three-dimensional shape data of the patient's teeth (three-dimensional data of the tooth appearance) is obtained. ) Can be obtained. In the first embodiment, the measuring device 1 also includes a CCD camera, and the CCD camera can also acquire data on the color, shape, and condition of the teeth in the oral cavity of the patient. .

Next, FIG. 3 is a flowchart showing the entire flow of the manufacturing process of the artificial tooth according to the first embodiment. First, the work by the dentist will be described. The dentist selects the size (large, medium, small) of the measuring device depending on whether the patient is an adult, a boy (girl), or an infant (step 31 in FIG. 3). Next, washing and disinfection are performed so that there is no danger of bacterial infection or the like even if the selected measuring instrument 1 is inserted into the oral cavity of the patient.
The measuring device 1 is sufficiently cleaned (the same step 32). Next, the cleaned measuring instrument 1 is inserted into the patient's mouth (step 33) to obtain three-dimensional shape data of the patient's teeth and also obtain data on the color of the patient's teeth. (Step 34). Next, the dentist uses the camera 2 to image the face of the patient, and acquires data on the shape and color of the patient's face (step 35). Next, the dentist displays, on the display device of the workstation 3, a simulation image showing the state when the patient has artificial teeth on the display device of the workstation 3 based on the data obtained from the measuring device 1 and the camera 2. Then, the patient is asked whether or not the artificial teeth can be attached (step 36).

Then, after cutting the patient's teeth (step 37), the dentist inserts the measuring device 1 again into the patient's mouth to acquire three-dimensional shape data in the mouth (see step 37). Step 38). Then, the dentist obtains the data (the three-dimensional shape data of the patient's teeth, the tooth color data, the data of the shape and color of the patient's face, and the tooth Is transmitted to the workstation 5 on the dental laboratory side via a communication medium such as a communication line (step 39).

After receiving these data, the workstation 5 of the dental laboratory converts the tooth shape data into CAD / CAM data of a predetermined format (step 40). This CAD / CAM data is
It is transferred to the NC cutting machine 6 (for example, a computer-controlled aqua jet machine). The NC cutting machine 6 (Aqua jet machine) uses the transferred CAD / CAM
Based on the data, by cutting a material such as gypsum or cement, a dental model that is almost the same as a dentist previously manufactured using an agar mold is automatically manufactured (at the same step). 41).

Thereafter, as in the conventional case, a tooth profile is formed from the dental model with wax (step 42).
By embedding the tooth profile of this wax in a dental investment material,
A mold is made (step 43). Then, a metal such as gold or silver is poured into the mold to cast a metal artificial tooth (step 44). After the surface of the cast artificial tooth is polished (step 45), a ceramic film is baked to adjust the color of the surface (step 46) according to the patient's request. The work of adjusting the color of the ceramic film is performed based on the color data of the patient's teeth, the color data of the patient's face, and the like transmitted from the dentist's workstation 3 in step 39 described above. Finally, the surface of the ceramic film is polished and the shape and color of the surface are adjusted (step 46). The adjustment work in this step 46 is also performed in the above-mentioned step 39 in the dentist's workstation
Is performed based on the patient's tooth color data, the patient's face shape or color data, and the like transmitted from the PC.

As described above, in this embodiment, the dentist measures the three-dimensional shape of the patient's teeth, transmits this three-dimensional shape data to the dental laboratory, and the dental laboratory
On the basis of the transmitted data, a dental model to be used for manufacturing an artificial tooth is created. Therefore, according to the present embodiment, compared to the case where conventional agar is used, without placing a burden or burden on the patient as in the past,
In a very short time, easily and accurately, the 3
The dimensional shape data can be obtained. In this embodiment, the three-dimensional shape data is transmitted to the dental laboratory, and the dental laboratory manufactures a mold for an artificial tooth based on the three-dimensional shape data. It is possible to manufacture artificial teeth within and with high precision.
In the first embodiment, the dental lab also transmits artificial tooth color data and patient face color or shape data to the dental lab side based on these data. Since the color and shape of the teeth are adjusted, it is possible to provide an artificial tooth that is more satisfactory for the patient even in terms of appearance.

Embodiment 2 Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, unlike the first embodiment, the dental laboratory converts data transmitted from the dentist into CAD / CAM data (step 40 in FIG. 4), and then creates a dental model. 3 (see step 41 of FIG. 3 described in connection with the first embodiment), the tooth profile of wax is cut using an NC machine tool (e.g., a computer-controlled aqua jet machine). (Step 51 in FIG. 4). After that, the same processing as in the first embodiment is performed. That is, the tooth profile of this wax is buried in the investment material to create a mold (step 4 in FIG. 4).
3) and processing such as casting an artificial tooth from the mold (step 44 in FIG. 4).

As described above, according to the second embodiment,
Since the tooth profile of wax is suddenly created (cut, etc.) without creating a dental model from the CAD / CAM data, the manufacturing process of the artificial tooth is further simplified as compared with the first embodiment.・ Efficiency can be improved, and artificial teeth can be manufactured in a shorter time.

Embodiment 3 FIG. Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, unlike the first embodiment, the dental laboratory converts the data transmitted from the dentist into CAD / CAM data (step 40 in FIG. 5), and then creates a dental model. (See step 41 of FIG. 3 described with reference to the first embodiment), and a tooth profile of the wax is created (the first embodiment).
(See step 42 of FIG. 3 described for
Suddenly, an artificial tooth is cut from a block (block) of ceramic, metal, or the like using an NC machine tool or the like (step 52 in FIG. 5). After that, the same processing as in the first embodiment is performed. That is,
The artificial teeth are polished, and a process such as baking a ceramic film is performed. That is, in the third embodiment, the artificial tooth is not “molded” by the “casting” method as in the first and second embodiments.
It is manufactured by performing "cutting" processing based on M data.

As described above, according to the third embodiment,
Since the artificial teeth are suddenly created (cutting, etc.) from the CAD / CAM data without creating the tooth model of the dental model or the wax, the artificial teeth are compared with the first and second embodiments. The manufacturing process can be simplified and made more efficient, and an artificial tooth can be manufactured in a shorter time.

The present invention is not limited to the contents described in each of the embodiments described above, and various changes can be made without departing from the gist of the present invention.

For example, in the above embodiment, the dentist inserts the measuring device 1 into the patient's mouth and captures the reflected light of the laser beam to acquire the three-dimensional shape data of the tooth. However, the present invention is not limited to this, and various methods are possible. For example, in the present invention, as a method of acquiring three-dimensional shape data of a patient's teeth, instead of using the above-mentioned method using laser light, teeth are imaged by two different CCD cameras at a fixed distance, and the image data is obtained. May be used to obtain the three-dimensional shape data of the tooth. Further, in the present invention, as a measuring instrument of a type to be inserted into the oral cavity of a patient, a measuring instrument which emits x-rays or a stylus type such as an input pen (only by tracing a contour of a patient's teeth with a pen) And a digital optical sensor connected to the pen for measuring the position and movement of the pen tip), or a device for measuring the position and movement of the pen tip by magnetism or ultrasonic waves.

In the present invention, a type of measuring instrument which is not inserted into the patient's mouth may be used to measure the three-dimensional shape data of the patient's teeth. This type of measuring device includes, for example, x from the front of the patient's mouth toward the teeth.
A type that scans around the teeth in parallel with the teeth while emitting lines (used by dentists,
It has the same principle as a device for taking radiographs of teeth. C
T scan) may be used.

In the present invention, the measuring instrument 1 and the camera 2 are inserted into the oral cavity of the patient to diagnose / examine the patient's alveolar pyorrhea, periodontal disease, caries, or tartar. It is also possible to obtain the data required for Also,
By installing the system of the present invention in a vehicle and going to the patient's home or workplace by the vehicle, the patient's teeth 3
If dimensional shape data, color data, and the like are acquired, preliminary examination and treatment can be performed.

[0032]

As described above, in the artificial tooth manufacturing system according to the present invention, regardless of the conventional agar,
Since the three-dimensional shape data of the patient's teeth is acquired by the measuring device, the three-dimensional shape data of the patient's teeth can be obtained using conventional agar.
Compared to the case where the three-dimensional shape data is obtained, the patient does not have to pay much pain or burden to obtain the three-dimensional shape data of the patient's teeth. In addition, in the method of obtaining three-dimensional shape data using the measuring device of the present invention, there is no difference due to variations in personal skills of doctors and nurses as in the case of using conventional agar. The three-dimensional shape data of the patient's teeth can be more accurately and accurately compared to the case where the three-dimensional shape data is obtained from agar as described above.
Will be able to gain. In addition, the inconvenience of repeatedly performing "retake" of the mold using agar as in the related art is eliminated.

In the present invention, the three-dimensional shape data obtained as described above is transmitted from the dentist to the dental laboratory via a communication medium such as a communication line. The production of artificial teeth on the laboratory side can be performed in a much shorter time than the conventional method. Also, since the three-dimensional shape data is transmitted to the dental laboratory as it is,
As in the past, there was no inconvenience such as the fact that the dental mold was deformed while the plaster mold was being sent from the dentist to the dental laboratory, and accurate data was not transmitted to the dental laboratory. Manufacturing can be performed more accurately and reliably.

In the present invention, since the three-dimensional shape data of the patient's tooth is transmitted to the dental laboratory as it is, the dental laboratory uses the transmitted three-dimensional shape data to generate an artificial tooth data based on the transmitted three-dimensional shape data. It is also possible to create a mold of the type or to create an artificial tooth directly.

Further, in the artificial tooth manufacturing system according to the present invention, laser light is emitted to the patient's teeth in the oral cavity of the patient, and the reflected light is measured, thereby obtaining the tooth 3.
By obtaining the three-dimensional shape data, the dentist can obtain the three-dimensional shape data of the patient's teeth extremely easily, with high accuracy, and within a short time.

Further, in the artificial tooth manufacturing method according to the present invention, the intraoral insertion type measuring instrument is cleaned before being inserted into the oral cavity of the patient. The danger of bacterial infection and the like is prevented.

Further, according to the present invention, the data on the color of the patient's teeth is also transmitted to the dental lab.
On the dental laboratory side, based on this data, it is possible to finish the color of the artificial tooth in the same way as the original natural tooth, so that it is possible to provide an artificial tooth that is more satisfactory for the patient.

In the present invention, data on the shape and color of the patient's face is also transmitted to the dental lab, so that the dental lab can generate an artificial tooth based on these data. Since the color and shape can be adjusted to match the shape and color of the patient's face, it is possible to provide an artificial tooth that is more satisfactory for the patient.

In the present invention, when a tooth profile of wax is to be immediately created (cutting or the like) without creating a dental model based on the measured tooth shape data of the patient, Since the step of preparing the conventional dental model can be omitted, the manufacturing process of the artificial tooth can be simplified and made more efficient, and the artificial tooth can be manufactured in a shorter time than in the conventional case.

Also, in the present invention, an artificial tooth is immediately created (cutting or the like) without creating a dental model or a tooth profile based on the measured tooth shape data of the patient. In this case, the step of creating a conventional dental model and the step of creating a tooth profile of wax can be omitted, so that the manufacturing process of an artificial tooth can be simplified and made more efficient than in the past, and the artificial tooth can be manufactured in a shorter time. Be able to manufacture teeth.
