Description

Method, device and recording medium for manufacturing a transparent orthodontic device

[0001] The present disclosure relates to a technology for obtaining a user's oral information and obtaining a transparent orthodontic device for a tooth model corresponding to the user's oral information.

[0002] Clear orthodontic devices, also known as aligners or Invisalign, are made of thin, transparent plastic and are shaped like a mouthpiece. Clear orthodontic devices are worn on the teeth to correct teeth without the use of wires or brackets, while also providing a pleasing appearance, making them widely used these days. Meanwhile, orthodontic treatment using clear orthodontic devices utilizes the natural tendency of teeth to shift when subjected to external force, gradually moving them to the desired position. Orthodontic treatment can be categorized into labial orthodontics, lingual orthodontics, and clear orthodontics. Clear orthodontics, which uses transparent plastic to gradually move teeth without the need for metal structures like brackets, has recently become widely used in orthodontic treatment. However, the existing method of manufacturing clear orthodontic devices relies on clear orthodontic sheets. This process involves using oral scanner data to create a 3D model of the teeth according to the treatment stage. The sheet and the model are then used in a thermoforming device to create the clear orthodontic device. Therefore, the transparent aligner is manufactured through a polishing process that removes the remaining parts from the remaining sheets after manufacturing the transparent aligner. This manufacturing method has the limitation that the remaining parts must be cut off and discarded when manufacturing the transparent aligner from the sheet, and the manufacturing time for the transparent aligner is long. In addition, when making a three-dimensional transparent aligner from a two-dimensional sheet, there is a limitation that the sheet stretches and changes in thickness, which causes the force on the transparent aligner to vary for each tooth, tooth surface, and patient. Therefore, there is a need for technology for a manufacturing method for a three-dimensional transparent aligner that does not cause changes in thickness.

[0003] One embodiment of the present disclosure is intended to solve the problems of the prior art described above, and to provide a method, device, and recording medium capable of reducing material consumption and shortening the working time in the process of manufacturing a transparent orthodontic device.

[0004] The technical problems to be solved are not limited to the technical problems described above, and may include various other technical problems within a scope obvious to a person skilled in the art.

[0011] In addition, the method further includes a step of generating a 3D image based on the statistical information and outputting the plurality of standard pre-aligners through a 3D printer; wherein the shapes of the plurality of standard pre-aligners can be formed based on the 3D shapes of the plurality of standard tooth models determined based on the statistical information.

[0012] Additionally, the internal space of the shape of the standard prealigner may include a free space that is maintained even after the standard tooth model is coupled to the standard prealigner.

[0013] Additionally, any standard pre-aligner shape among the plurality of standard pre-aligners may be a shape corresponding to any one of the plurality of standard tooth models.

[0014] A device for manufacturing a transparent orthodontic device according to a second aspect of the present disclosure may include a receiving unit for acquiring oral cavity information of a user; and a processor for acquiring specification information for a plurality of standard pre-aligners generated based on statistical information, determining one of the plurality of standard pre-aligners based on the oral cavity information and the specification information, acquiring a tooth model corresponding to the oral cavity information, and modifying the determined standard pre-aligner to correspond to the tooth model to obtain a transparent orthodontic device corresponding to the tooth model.

[0015] In addition, the processor controls a vacuum heat treatment unit to perform heat treatment and vacuum treatment while the determined standard prealigner and the tooth model are combined, and after performing the heat treatment and the vacuum treatment, the transparent orthodontic device can be separated from the tooth model.

Alternatively, a fourth aspect of the present disclosure may provide a computer program stored on a recording medium for implementing the method according to the first aspect.

[0020] According to one embodiment, by providing a three-dimensional shape for manufacturing a custom, ready-made transparent aligner without using a sheet, the transparent aligner is obtained, thereby reducing material consumption in that there is no need to discard any remaining material after manufacturing.

[0021] In addition, since a 3D shape for manufacturing a custom-made transparent orthodontic device is provided, a transparent orthodontic device in a 3D shape is obtained, which has the advantage of not causing a change in thickness during the manufacturing process, and also has the effect of shortening the manufacturing period.

[0035]

[0036] FIG. 1 is a block diagram showing an example of the configuration of a device (100) according to one embodiment.

For example, the device (100) may further include memory (not illustrated). Alternatively, those skilled in the art will appreciate that, according to other embodiments, some of the components illustrated in FIG. 1 may be omitted.

[0039] According to one embodiment, the receiving unit (110) can obtain information about the user's oral cavity. For example, the receiving unit (110) can receive oral cavity information or a 3D image of the oral cavity from an external device. However, this embodiment is not limited thereto, and the device (100) can also obtain oral cavity information by obtaining multiple images corresponding to the user's oral cavity.

[0040] Oral information can be generated based on various data acquired about the oral cavity.

Furthermore, the processor (120) may modify the determined standard pre-aligner to correspond to the tooth model, thereby obtaining a transparent orthodontic device corresponding to the tooth model.

[0042] The embodiments described above with reference to FIG. 1 will be described in more detail with reference to FIGS. 2 to 6.

[0043] FIG. 2 is a flowchart illustrating each step of obtaining a transparent orthodontic device by a device (100) according to one embodiment.

[0044] In step S210, the device (100) according to one embodiment obtains specification information for a plurality of standard prealigners generated based on statistical information.

[0045] In one embodiment, the plurality of standard pre-aligners may include a plurality of preset aligners, which are aligners generated based on statistical information about various tooth models acquired from an external device or an external server. That is, the plurality of standard pre-aligners may correspond to a plurality of pre-formed transparent devices. The device (100) may acquire a plurality of pre-formed transparent devices, which may be predicted to have a standard shape based on the statistical information, as the plurality of standard pre-aligners. The device (100) may acquire specification information for each of the plurality of standard pre-aligners. In one embodiment, the specification information may include information about the arch length indicating the front-to-back length of the arch, the arch width indicating the left-right width of the arch, and the tooth width indicating the width of the teeth. Accordingly, the device (100) may acquire the arch length, the arch width, and the tooth width for each of the plurality of standard pre-aligners representing the plurality of preset aligners.

[0046] In step S220, the device (100) according to one embodiment obtains the user's oral information.

[0047] In one embodiment, oral information may refer to information about the shape of the teeth, dentition, etc. of a user who wishes to wear a transparent orthodontic device. For example, the device (100) may acquire 3D data generated using scan data or CT data of a plurality of teeth of the user as oral information. In addition, the device (100) may generate oral information by acquiring scan data or CT data of a plurality of teeth, or may acquire oral information from an external device.

[0048] In step S230, the device (100) according to one embodiment determines one of a plurality of standard prealigners based on oral information and specification information.

[0049] In one embodiment, the device (100) can determine one standard pre-aligner among the plurality of standard pre-aligners that is expected to be suitable for the user's oral cavity by comparing oral information corresponding to the user's tooth shape, dentition, etc. with specification information corresponding to the arch length, arch width, and tooth width of the plurality of standard pre-aligners.

[0050] In step S240, the device (100) according to one embodiment obtains a tooth model corresponding to oral information.

[0051] In one embodiment, the tooth model is a model corresponding to the user's oral cavity, and may mean a tooth model in a desired state by the user or a tooth model determined based on the user's oral cavity information.

[0052] In step S250, the device (100) according to one embodiment transforms the determined standard prealigner to correspond to the tooth model to obtain a transparent orthodontic device corresponding to the tooth model.

[0053] In one embodiment, the device (100) can transform a standard pre-aligner determined from among a plurality of standard pre-aligners corresponding to a plurality of pre-molded devices to correspond to a tooth model. For example, when the determined standard pre-aligner and the tooth model are combined, the device (100) can perform heat treatment and vacuum treatment on the standard pre-aligner by controlling the vacuum heat treatment unit (130). Accordingly, after performing the heat treatment and vacuum treatment, the device (100) can separate the transparent orthodontic device corresponding to the tooth model. In one embodiment, an example of determining one of the plurality of standard pre-aligners and an example of obtaining the transparent orthodontic device will be described with reference to FIGS. 3 to 6.

[0054] FIG. 3 is a drawing illustrating an example of a device (100) according to one embodiment obtaining the arch length and arch width for a plurality of standard pre-aligners.

[0055] Referring to FIG. 3, a device (100) according to an embodiment can obtain a ridge length (310) and a ridge width (320) representing specification information for each of a plurality of standard pre-aligners. That is, as illustrated in FIG. 3, the device (100) can obtain a ridge length (310) representing the front-back length of the ridge of each of a plurality of standard pre-aligners, and a ridge width (320) representing the left-right width of the ridge.

[0056] FIG. 4 is a drawing illustrating an example of a device (100) according to one embodiment obtaining tooth widths for a plurality of standard prealigners.

[0057] Referring to FIG. 4, a device (100) according to an embodiment can obtain a tooth width for each section representing the width of a tooth. Specifically, the device (100) can obtain a first anterior tooth width (410) and a second anterior tooth width (420) corresponding to an anterior tooth, and can obtain a posterior tooth width (430) corresponding to a posterior tooth. In one embodiment, the first anterior tooth width (410) may be a tooth width corresponding to an anterior tooth (central incisor and lateral incisor), and the second anterior tooth width (420) may be a tooth width corresponding to a canine located at the third position on either side from an anterior tooth. In addition, the posterior tooth width (430) may be a tooth width corresponding to any one of teeth located at the fourth or more positions on either side from an anterior tooth. In one embodiment, the range of the anterior tooth width of the plurality of standard pre-aligners may be determined to be in a range between 20 mm and 24 mm, and the range of the posterior tooth width may be determined to be in a range between 22 mm and 25 mm. In one embodiment, the device (100) may obtain user arch length information, user arch width information, and user tooth width information for the user based on oral information. The device (100) may determine a corresponding standard pre-aligner among the plurality of standard pre-aligners based on the user arch length information, the user arch width information, and the user tooth width information. That is, the device (100) may determine a standard pre-aligner that best corresponds to the user's oral information by comparing the user arch length information, the user arch width information, and the user tooth width information with the specification information of each of the plurality of standard pre-aligners. The user tooth width may include the tooth width of the user's anterior teeth and the tooth width of the user's posterior teeth.That is, the user tooth width may include the tooth width at a position corresponding to the first anterior tooth width (410), the second anterior tooth width (420), and the posterior tooth width (430) of the plurality of standard pre-aligners described above. Accordingly, the device (100) may determine the most corresponding standard pre-aligner by comparing the tooth width of the user anterior teeth and the tooth width of the user posterior teeth with the first anterior tooth width (410), the second anterior tooth width (420), and the posterior tooth width (430) of the plurality of standard pre-aligners among the user arch length information and one or more standard pre-aligners having an arch length (310) and an arch width (320) similar to the user arch width information.

[0058] FIG. 5 is a drawing illustrating an example in which a device (100) according to one embodiment determines one of a plurality of standard pre-aligners based on a user's arch type.

[0059] Referring to FIG. 5, in one embodiment, the arch type may be one of a U-shape indicating a rectangular shape, which is a Square type, an O-shape indicating an oval shape, which is an Ovoid type, and a V-shape indicating a gradually narrowing shape, which is a Tapered type. The device (100) according to one embodiment may determine the user arch type as any one of a U-shape, an O-shape, and a V-shape. The device (100) may determine one of a plurality of standard pre-aligners based on the determined user arch type. For example, the device (100) may determine a standard pre-aligner corresponding to the user arch type among at least one standard pre-aligner corresponding to the user arch length information, the user arch width information, and the user tooth width information. Accordingly, a standard pre-aligner to which information about the user's arch type is applied together with oral cavity information may be determined as the standard pre-aligner corresponding to the user.

[0060] FIG. 6 is a drawing for explaining an example of obtaining a transparent orthodontic device (630) in a three-dimensional shape according to one embodiment.

[0061] Referring to FIG. 6, a device (100) according to an embodiment can deform one of a plurality of standard pre-aligners representing a pre-formed device to correspond to a user's tooth model (610). The user's tooth model (610) is generated to have the same shape as the tooth shape according to the user's oral structure. For example, a 3D scanner is used to scan the user's oral structure, and the user's tooth model (610) is generated based on the scan data. Accordingly, a 3D printer can be used. The scan data acquired using the 3D scanner can be output through a 3D printer to output the user's tooth model (610). In an embodiment, the device (100) can deform a standard pre-aligner (620) determined as one of the plurality of standard pre-aligners to correspond to the shape of the user's tooth model (610) by controlling a vacuum heat treatment unit (130). Accordingly, the device (100) can obtain a transparent orthodontic device (630) in which the determined standard pre-aligner (620) is modified. In one embodiment, the device (100) can generate a 3D image based on statistical information and output a plurality of standard pre-aligners through a 3D printer. For example, the shapes of the plurality of standard pre-aligners are formed based on the 3D shapes of the plurality of standard tooth models determined based on the statistical information. The shape of any standard pre-aligner among the plurality of standard pre-aligners may be a shape corresponding to any one of the plurality of standard tooth models. For example, the standard tooth model may be a tooth model obtained based on statistical information on the tooth specifications and sizes of Asians. The shape of the standard pre-aligner may be a shape combined with each of one or more standard tooth models that exhibit characteristics such as various dimensions and various heights classified according to a standard specification range representing the tooth specifications or sizes of Asians.For example, by classifying the tooth specifications and sizes of Asians and using the dimensions, heights, etc., a plurality of standard pre-aligners corresponding to the shape for being combined with a preset number (e.g., 9) of standard tooth models can be obtained. In one embodiment, the internal space of the standard pre-aligner shape can include a free space that is maintained even after the standard tooth model is combined with the standard pre-aligner.

[0062] Referring to FIG. 6, an example of a standard pre-aligner (620) determined to be coupled to a user's tooth model (610) corresponding to the user's oral information can be confirmed. As illustrated in the first step of FIG. 6, the determined standard pre-aligner (620) can be coupled to the user's tooth model (610). Accordingly, the device (100) controls the vacuum heat treatment unit (130) to perform heat treatment and vacuum treatment on the determined standard pre-aligner (620) while coupled to the user's tooth model (610), thereby obtaining a transparent orthodontic device (630) corresponding to the user's oral information. That is, the vacuum heat treatment unit (130) can perform heat treatment and vacuum treatment on the determined standard pre-aligner (620) coupled to the user's tooth model (610), and then separate it from the user's tooth model (610). Accordingly, a transparent orthodontic device (630) that is modified to correspond to the user's tooth model (610) by heat-treating and vacuum-treating the determined standard pre-aligner (620) can be obtained. In one embodiment, the internal space representing the area where the standard pre-aligner is coupled to the tooth model may include a free space that is maintained even after being coupled to the standard tooth model. For example, the shape of the standard pre-aligner may be determined to be a size that is a certain level larger than the shape of the standard tooth model generated according to the standard specification range so as to include the free space. That is, a plurality of standard pre-aligners corresponding to a preset number (e.g., 9) may have a shape such that the internal space of each standard pre-aligner shape includes a free space that exceeds the area of ​​each shape of the plurality of standard tooth models. Therefore, heat-treating and vacuum-treating may be performed in a state where the standard pre-aligner (620), which is determined as one of the plurality of standard pre-aligners, is coupled to the user's tooth model (610) corresponding to the user's oral information. Accordingly, a transparent orthodontic device (630) corresponding to the shape of the user's tooth model (610) can be obtained as shown in the last step of FIG. 6.According to the present invention, since a plurality of standard pre-aligners of a preset number are combined with a user's tooth model (610) to perform heat treatment and vacuum treatment, a thickness change that may occur during the heat treatment process when obtaining a transparent orthodontic device (630) using a conventional transparent sheet can be prevented. That is, according to the present invention, since a plurality of standard pre-aligners representing a pre-formed device are used, a 3D model can be obtained from a 3D model, so there is an advantage in that a thickness change can be applied uniformly. In addition, when obtaining a transparent orthodontic device (630) using a conventional transparent sheet, a process of cutting and polishing a portion of the sheet is necessary, whereas according to the present invention, since the determined standard pre-aligner (620) exists in a 3D shape corresponding to the transparent orthodontic device (630), there is an advantage in that a polishing process is unnecessary.
