[First Embodiment]
Hereinafter, a method for manufacturing a mouthguard according to the first embodiment of the present invention will be described with reference to the drawings.

In the method for manufacturing a mouse guard according to the present embodiment, for example, as shown in FIG. 1, a 3D scanner (3D scanner) 1, a 3D printer (3D modeling device) 2, and an information processing device 3 for operating these are used. , 4 and tooth model 5 and the like are used. The information processing devices 3 and 4 are composed of, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a computer-readable storage medium, and the like. As an example, a series of processes for realizing various functions are stored in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing / arithmetic processing. As a result, various functions are realized. The program is installed in a ROM or other storage medium in advance, is provided in a state of being stored in a computer-readable storage medium, or is distributed via a wired or wireless communication means. Etc. may be applied. The computer-readable storage medium is a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.

The information processing apparatus 3 performs arithmetic processing on the three-dimensional shape data acquired by the 3D scanner 1 to create three-dimensional modeling mold shape data relating to the shape of the tooth model 5. The three-dimensional modeling mold shape data in the present embodiment is an example of the mold shape data according to the present invention. The information processing apparatus 4 executes the operation of the 3D printer 2 based on the three-dimensional modeling mold shape data.

The tooth model 5 is formed by the 3D printer 2 and is used as a molding so that the mouth guard has a shape corresponding to the shape of the wearer's teeth.

In the present embodiment, three-dimensional shape data in the oral cavity including the shape of the teeth of the wearer wearing the mouth guard is acquired, and the tooth model 5 is formed based on the acquired three-dimensional shape data. In the present embodiment, the tooth model 5 is modeled and created by the 3D printer 2 based on the acquired three-dimensional shape data. The three-dimensional modeling method using the 3D printer 2 is not limited, but is, for example, a liquid tank photopolymerization (photomodeling) method. Then, after the tooth model 5 is formed, the resin material which is the material of the mouth guard is pressed against the tooth model 5 to form the mouth guard.

As shown in FIG. 2, first, by scanning with the 3D scanner 1, the shape of the oral cavity including the wearer's teeth, that is, the shape of the dentition and the shape of the maxilla or mandible is acquired as three-dimensional shape data (step S11). .. The three-dimensional shape data includes information on the shape dimensions of the wearer's actual teeth and the like. The acquired three-dimensional shape data is temporarily recorded in the storage device. The storage device has a storage medium such as a memory and a hard disk, and may be built in a locally installed personal computer, a server device connected via the Internet, or the like. The information processing device 3 (for example, a personal computer) for creating the three-dimensional modeling mold shape data relating to the tooth mold model 5 acquires the three-dimensional shape data from the storage device.

Next, three-dimensional modeling mold shape data regarding the shape of the tooth model 5 is created so that the tooth model 5 is modeled by the 3D printer 2 (step S12). At this time, the shape dimensions of the wearer's actual teeth and the like in the three-dimensional shape data are calculated, and as described later, the shape dimensions of the three-dimensional modeling mold data are different from the shape dimensions of the actual teeth and the like. Contains information about dimensions.

The 3D modeling mold shape data is data relating to the outer shape of the tooth model 5, and is created based on the acquired 3D shape data, for example, using 3D CAD software. The created three-dimensional modeling mold shape data is temporarily recorded in the storage device. The storage device has a storage medium such as a memory and a hard disk, and may be built in a locally installed personal computer, a server device connected via the Internet, or the like. The information processing device 4 (for example, a personal computer or the like) for operating the 3D printer 2 acquires 3D modeling mold shape data from the storage device.

After that, the tooth model 5 is modeled by the 3D printer 2 based on the three-dimensional modeling mold shape data regarding the created tooth model 5 (step S13). The operation of the 3D printer 2 is controlled by, for example, the information processing device 4. When the modeling by the 3D printer 2 is completed, finishing such as removing the support portion from the modeled object formed by the 3D printer 2 is performed, and the tooth model 5 is completed. As the material of the tooth model 5, a material usually used as a material of the tooth model 5, particularly a material suitable for the tooth model 5 when being modeled by the 3D printer 2 is applied.

After the tooth model 5 is completed, the resin material which is the material of the mouth guard is pressure-bonded to the tooth model 5 while being heated. As a result, a mouthguard is formed corresponding to the shape of the tooth model 5 (step S14). After the resin material is molded to fit the tooth model 5, the mouthguard is completed by finishing. As the material of the mouth guard, the material usually used as the material of the mouth guard is applied.

Next, a method of creating the three-dimensional modeling mold shape data regarding the tooth mold model 5 and a method of forming the tooth mold model 5 based on the three-dimensional modeling mold shape data will be described.

The 3D modeling mold shape data is created by enlarging or reducing the shape dimensions of the 3D shape data, not the actual values of the tooth shape dimensions of the 3D shape data. For example, the shape dimension of the three-dimensional shape data is enlarged or reduced so that the tooth model 5 has a similar shape to the actual tooth. It should be noted that the enlargement or reduction with respect to the shape dimension of the three-dimensional shape data is not limited to the case where the shape is similar as a whole, and only the tooth portion or the jaw portion may be the similar shape, or the width direction, Only one of the depth direction and the height direction may be enlarged or reduced. The width direction, the depth direction, and the height direction correspond to, for example, the X-axis direction, the Y-axis direction, and the Z-axis direction orthogonal to each other in the three-dimensional CAD software.

Since the three-dimensional modeling mold shape data is created based on the enlarged or reduced shape dimensions, the 3D printer 2 forms a tooth mold model 5 having dimensions different from the actual tooth shape dimensions.

Then, by crimping the resin material to the tooth model 5 thus formed, a mouthguard having dimensions enlarged or reduced with respect to the actual tooth shape is formed. Mouthguards with dimensions smaller than the actual tooth shape are securely attached to the teeth and jaw. In addition, the mouthguard, which has a size larger than the actual tooth shape, can be easily attached to and detached from the tooth.

For example, when expanding the shape dimension of the 3D shape data, it is 100.2% of the shape dimension of the 3D shape data, and when reducing the shape dimension of the 3D shape data, the 3D shape data. It is set to 99.8% with respect to the shape dimension of. It should be noted that these magnifications are examples, and the magnifications applied to the present invention are not limited to these examples. The magnification of enlargement or reduction is set within a range in which the original function of the mouthguard is maintained when the mouthguard is attached to the tooth.

Since the 3D modeling mold shape data can be created by arbitrarily changing the magnification of the 3D shape data in the information processing device 3, the wearer's tooth arrangement, orientation, fit, etc. are taken into consideration. It can be created by determining the magnification. Conventionally, a dental model is formed by making a mold using an impression material by a dentist such as a dental clinic, and then pouring plaster into the mold by a dental technician such as a dental laboratory. In this case, since the shape and dimension of the mold cannot be changed by the impression material, it is difficult to form a tooth mold model different from the actual shape and dimension of the tooth of the wearer.

On the other hand, in the present embodiment, the shape of the oral cavity including the wearer's teeth is acquired as three-dimensional shape data by scanning with the 3D scanner 1, and then the tooth model 5 is based on the three-dimensional shape data. Is modeled and created by the 3D printer 2, so that the shape and dimensions of the tooth model 5 can be easily adjusted. Therefore, unlike the conventional mouth guard, it is possible to easily form a mouth guard having dimensions different from the actual tooth shape dimensions. And since the mouthguard, which has dimensions smaller than the actual tooth shape, is securely attached to the teeth and jaw, you can feel the fit that it is securely attached, and exercise performance is improved. In some cases. In addition, the mouthguard, which has a size larger than the actual tooth shape, is different from the case where the actual tooth size is the same, and even if the tooth arrangement and orientation are such that the mouthguard is difficult to put on and take off, it can be attached to and removed from the tooth. It will be easier.

Hereinafter, a method for manufacturing a mouthguard according to a second embodiment of the present invention will be described with reference to the drawings. In the above-mentioned first embodiment, the case where the tooth model 5 is formed by the 3D printer 2 and then the resin material is crimped to the tooth model 5 to form the mouth guard has been described, but the present invention describes this example. Not limited to. As will be described later in this embodiment, the mouthguard may be formed by the 3D printer 2 without forming the tooth model 5.

In the method for manufacturing a mouse guard according to the present embodiment, for example, as shown in FIG. 3, a 3D scanner (3D scanner) 1, a 3D printer (3D modeling device) 2, and information processing for operating these are performed. Devices 3 and 4 and the like are used. The information processing devices 3 and 4 are composed of, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a computer-readable storage medium, and the like. As an example, a series of processes for realizing various functions are stored in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing / arithmetic processing. As a result, various functions are realized. The program is installed in a ROM or other storage medium in advance, is provided in a state of being stored in a computer-readable storage medium, or is distributed via a wired or wireless communication means. Etc. may be applied. The computer-readable storage medium is a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.

The information processing device 3 performs arithmetic processing on the three-dimensional shape data acquired by the 3D scanner 1 to create the three-dimensional modeling mouse guard shape data. The information processing apparatus 4 executes the operation of the 3D printer 2 based on the three-dimensional modeling mouse guard shape data.

In the present embodiment, three-dimensional shape data in the oral cavity including the shape of the teeth of the wearer wearing the mouth guard is acquired, and the mouth guard is modeled and created by the 3D printer 2 based on the acquired three-dimensional shape data. To. The three-dimensional modeling method using the 3D printer 2 is not limited, but is, for example, a liquid tank photopolymerization (photomodeling) method. That is, the 3D printer 2 forms the mouth guard by applying the resin material which is the material of the mouth guard without forming the tooth model 5.

As shown in FIG. 4, first, by scanning with the 3D scanner 1, the shape of the oral cavity including the wearer's teeth, that is, the shape of the dentition and the shape of the maxilla or mandible is acquired as three-dimensional shape data (step S21). .. The three-dimensional shape data includes information on the shape dimensions of the wearer's actual teeth and the like. The acquired three-dimensional shape data is temporarily recorded in the storage device. The storage device has a storage medium such as a memory and a hard disk, and may be built in a locally installed personal computer, a server device connected via the Internet, or the like. The information processing device 3 (for example, a personal computer) for creating the three-dimensional modeling mouse guard shape data relating to the mouse guard acquires the three-dimensional shape data from the storage device.

Next, three-dimensional modeling mouse guard shape data regarding the shape of the mouth guard is created so that the mouth guard is modeled by the 3D printer 2 (step S22). At this time, the shape dimensions of the wearer's actual teeth and the like in the three-dimensional shape data are calculated, and as will be described later, the shape dimensions of the actual teeth and the like are included in the three-dimensional modeling mouse guard shape data. Contains information about different dimensions.

The 3D modeling mouse guard shape data is data relating to the outer shape of the mouse guard, and is created based on the acquired 3D shape data, for example, using 3D CAD software. The created three-dimensional modeling mouthguard shape data is temporarily recorded in the storage device. The storage device has a storage medium such as a memory and a hard disk, and may be built in a locally installed personal computer, a server device connected via the Internet, or the like. The information processing device 4 (for example, a personal computer or the like) for operating the 3D printer 2 acquires 3D modeling mouse guard shape data from the storage device.

After that, the mouth guard is modeled by the 3D printer 2 based on the created three-dimensional modeling mouse guard shape data (step S23). The operation of the 3D printer 2 is controlled by, for example, the information processing device 4. When the modeling by the 3D printer 2 is completed, finishing such as removing the support portion from the modeled object formed by the 3D printer 2 is performed, and the mouth guard is completed. As the material of the mouthguard, a material usually used as a material of the mouthguard, particularly a material suitable for the mouthguard when it is modeled by the 3D printer 2, is applied.

Next, a method of creating mouth guard shape data for three-dimensional modeling will be described.

The 3D modeling mouse guard shape data is not the value of the actual tooth shape dimension of the 3D shape data, but is created by enlarging or reducing the shape dimension of the mouse guard shape data related to the shape of the mouse guard. Will be done. The mouthguard shape data is created based on the three-dimensional shape data.

That is, as shown in FIG. 5, first, based on the three-dimensional shape data, a virtual reference mouthguard having the actual tooth shape dimensions is created in the information processing device 3 so as to correspond to the actual tooth. (Step S31). As a result, the mouthguard shape data regarding the reference mouthguard is acquired (step S32). Then, the mouthguard shape data for three-dimensional modeling is created by enlarging or reducing the shape dimension with respect to the mouthguard shape data of the virtual reference mouthguard (step S33).

The shaped mouthguard has, for example, a dimension in which the shape dimension of the reference mouthguard is enlarged or reduced so as to have a similar shape to a virtual reference mouthguard having the actual tooth shape dimension. It should be noted that the enlargement or reduction with respect to the shape dimension of the virtual reference mouth guard is not limited to the case where the shape is similar as a whole, and only the tooth part or only the jaw part may be made into the similar shape, or the width. Only one of the directions, the depth direction and the height direction may be enlarged or reduced.

Since the 3D modeling mouthguard shape data is created based on the shape dimensions enlarged or reduced with respect to the virtual reference mouth guard having the actual tooth shape dimensions, the actual tooth guard 2 can be used. A mouthguard with dimensions different from the tooth shape dimensions is formed. Mouthguards with dimensions smaller than the actual tooth shape are securely attached to the teeth and jaw. In addition, the mouthguard, which has a size larger than the actual tooth shape, can be easily attached to and detached from the tooth.

For example, when expanding the shape dimension of the reference mouth guard, it is set to 100.2% of the shape dimension of the mouth guard shape data regarding the reference mouth guard, and when reducing the shape dimension of the reference mouth guard, the reference mouse is used. It is set to 99.8% with respect to the shape dimension of the mouth guard shape data regarding the guard. It should be noted that these magnifications are examples, and the magnifications applied to the present invention are not limited to these examples. The magnification of enlargement or reduction is set within a range in which the original function of the mouthguard is maintained when the mouthguard is attached to the tooth.

Since the mouse guard shape data for 3D modeling can be created in the information processing device 3 by arbitrarily changing the magnification with respect to the mouse guard shape data of the reference mouse guard based on the 3D shape data, the wearer's teeth It is possible to determine the magnification and create it in consideration of the arrangement, orientation, fit, etc.

Therefore, it is easy to adjust the shape and dimensions of the mouse guard. Therefore, unlike the conventional mouth guard, it is possible to easily form a mouth guard having dimensions different from the actual tooth shape dimensions. And since the mouthguard, which has dimensions smaller than the actual tooth shape, is securely attached to the teeth and jaw, you can feel the fit that it is securely attached, and exercise performance is improved. In some cases. In addition, the mouthguard, which has a size larger than the actual tooth shape, is different from the case where the actual tooth size is the same, and even if the tooth arrangement and orientation are such that the mouthguard is difficult to put on and take off, it can be attached to and removed from the tooth. It will be easier.

In the second embodiment described above, a virtual reference mouthguard having actual tooth shape dimensions is created, and the shape dimensions are enlarged or reduced with respect to the created reference mouth guard for three-dimensional modeling. Although the case where the mouthguard shape data is created has been described, the procedure for creating the mouthguard shape data for three-dimensional modeling is not limited to this method in the present embodiment.

For example, unlike the first embodiment, unlike the second embodiment, the tooth model is not actually formed, but the information processing apparatus 3 creates a virtual mouth guard mold to create a virtual mouth guard. The shape dimension of the mold may be enlarged or reduced. Then, three-dimensional modeling mouthguard shape data regarding the shape of the mouthguard is created so as to correspond to the virtual mouthguard mold.

Hereinafter, this example will be described as a modified example of the method for creating the mouthguard shape data for three-dimensional modeling according to the second embodiment.

In this modification, the 3D modeling mouse guard shape data is created by enlarging or reducing the shape dimensions of the 3D shape data, not the values of the actual tooth shape dimensions of the 3D shape data. Will be done. For example, in the information processing apparatus 3, the shape dimension of the three-dimensional shape data is enlarged or reduced so that the virtual mouse guard mold has a similar shape to the actual tooth. It should be noted that the enlargement or reduction with respect to the shape dimension of the three-dimensional shape data is not limited to the case where the shape is similar as a whole, and only the tooth portion or the jaw portion may be the similar shape, or the width direction, Only one of the depth direction and the height direction may be enlarged or reduced.

(Step S41). As a result, the mold shape data of the virtual mouthguard type is acquired (step S42). The virtual mouthguard mold shape data in this modification is an example of the mold shape data according to the present invention.
