Description

[Technical Field] This disclosure relates to a technique for acquiring a user's oral cavity information and obtaining a transparent orthodontic appliance based on a dental model corresponding to the user's oral cavity information. [Background Technology] Clear aligners, also known as braces or by brand names like Invisalign, are made of thin, transparent plastic. They are worn without archwires or brackets to straighten teeth and offer a pleasing aesthetic appearance, leading to their widespread use in recent years.

[0003] On the other hand, related to this, orthodontic treatment using clear aligners utilizes the property of teeth to move under external force, gradually moving them to the desired position. Orthodontic treatment can be categorized into labial braces, lingual braces, and clear aligners. Clear aligners, however, do not require metal structures like brackets attached to the mouth; instead, they use transparent plastic to guide the teeth to move gradually, thus achieving orthodontic correction. Therefore, they have been widely used in orthodontic treatment in recent years.

[0004] However, current methods for manufacturing clear aligners actually utilize clear aligner sheets. In this case, data from an oral scanner is used, and a dental model is output via 3D printing based on the treatment stage. The clear aligner is then manufactured using the sheet and the dental model in a thermoforming machine. Therefore, a polishing step is required to smooth out the trimming lines after removing the remaining sheet, thus creating the clear aligner.

[0005] This manufacturing method has the following limitations: when making clear aligners from sheet material, the remaining portion needs to be cut off and discarded, and the manufacturing cycle for clear aligners is relatively long. Furthermore, in the process of manufacturing three-dimensional clear aligners from two-dimensional sheet material, the thickness changes as the sheet is stretched, resulting in variations in the force applied by the clear aligner to different teeth, different tooth surfaces, and different patients.

[0006] Therefore, there is an urgent need for a method and technology for manufacturing transparent orthodontic appliances that can prevent changes in thickness when manufacturing three-dimensional transparent orthodontic appliances.

[0015] Furthermore, the method may also include the steps of generating a 3D image based on the statistical information and outputting the plurality of standard preformed orthodontic appliances through a 3D printer, wherein the shape of the plurality of standard preformed orthodontic appliances can be formed based on the 3D shape of a plurality of standard dental models, the plurality of standard dental models being determined based on the statistical information.

[0016] Furthermore, the internal space of the shape of the standard preformed orthodontic appliance can be configured to define a gap that is maintained even after the standard dental model is combined with the standard preformed orthodontic appliance.

[0017] Furthermore, the shape of any one of the plurality of standard preformed orthodontic appliances can be a shape corresponding to any one of the plurality of standard dental models.

[0018] A clear aligner manufacturing apparatus according to a second aspect of this disclosure may include: a receiving unit that acquires oral information of a user; and a processor that acquires specification information of a plurality of standard preformed aligners generated based on statistical information, determines one of the plurality of standard preformed aligners based on the oral information and the specification information, acquires a tooth model corresponding to the oral information, and acquires a clear aligner corresponding to the tooth model by deforming the determined standard preformed aligner to correspond to the tooth model.

[0019] Furthermore, the processor can control the vacuum heat treatment unit to perform heat treatment and vacuum treatment in the state where the determined standard preformed orthodontic appliance is combined with the dental model, and after performing the heat treatment and vacuum treatment, the clear appliance can be separated from the dental model.

[0020] In addition, the specification information may include information about the dental arch length, dental arch width, and tooth width.

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

[0024] [Beneficial Effects] According to one embodiment, since clear aligners are obtained by providing a three-dimensional shape for manufacturing customized finished clear aligners instead of using sheets, there is no need to discard the remaining material after manufacturing, thereby reducing material consumption.

[0025] Furthermore, since the transparent orthodontic appliance is obtained from a three-dimensional shape by providing a three-dimensional shape for manufacturing a customized finished product, it has the advantage that no thickness change occurs during the manufacturing process, and also has the effect of shortening the manufacturing cycle.

Furthermore, terms such as "...part" in the specification refer to a unit that processes at least one function or action, which may be implemented by hardware or software, or by a combination of hardware and software.

[0035] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement this disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein.

[0036] Throughout the instruction manual, "region" can be interpreted as a concept encompassing both two-dimensional and three-dimensional dimensions.

[0037] Hereinafter, several embodiments will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 This is a block diagram illustrating an example configuration of a device 100 according to one embodiment.

[0039] Reference Figure 1 The device 100 may include a receiving unit 110, a processor 120, and a vacuum heat treatment unit 130.

[0040] Those skilled in the art will understand that, except Figure 1 In addition to the components shown, device 100 may further include other general components. For example, device 100 may further include a memory (not shown). Alternatively, according to another embodiment, those skilled in the art will understand that... Figure 1 Some of the constituent elements shown may be omitted.

[0041] According to one embodiment, the receiving unit 110 can acquire a user's oral cavity information. For example, the receiving unit 110 can receive oral cavity information or 3D images of the oral cavity from an external device, but it is not limited to this embodiment. The device 100 can also acquire oral cavity information by acquiring multiple images corresponding to the user's oral cavity.

[0042] Oral information can be generated based on various data acquired about the oral cavity. For example, oral information can also be acquired based on scan data and / or CT data about the oral cavity. CT data and scan data can be received via scanners or external devices. (See reference...) Figure 1 The wireless terminal 140 or the wired terminal 150 may be an example of an external device.

[0043] According to one embodiment, the processor 120 can acquire specification information about multiple standard preformed orthodontic appliances generated based on statistical information. Furthermore, the processor 120 can determine one of the multiple standard preformed orthodontic appliances based on oral information and specification information. Additionally, the processor 120 can acquire a tooth model corresponding to the oral information. Furthermore, the processor 120 can obtain a clear aligner corresponding to the tooth model by deforming the determined standard preformed orthodontic appliance to correspond to the tooth model.

[0044] Reference above Figure 1 The embodiments described below will be referred to. Figures 2 to 6 To explain in more detail.

[0045] Figure 2 This is a flowchart illustrating the steps of acquiring a clear orthodontic appliance according to an embodiment of the apparatus 100.

[0046] In step S210, the apparatus 100 according to one embodiment obtains specification information about a plurality of standard preformed orthodontic appliances generated based on statistical information.

[0047] In one embodiment, the plurality of standard preformed orthodontic appliances are generated based on statistical information about various dental models obtained from external devices or external servers, and may include a plurality of pre-defined appliances. That is, the plurality of standard preformed orthodontic appliances may correspond to preformed clear devices. Device 100 may acquire a plurality of preformed clear devices that can be predicted to have a standard shape as a plurality of standard preformed orthodontic appliances based on statistical information.

[0048] The device 100 can acquire specification information for each of the plurality of standard preformed orthodontic appliances. In one embodiment, the specification information may include information about arch length, arch width, and tooth width, wherein the arch length represents the anteroposterior length of the arch, the arch width represents the lateral width of the arch, and the tooth width represents the width of the tooth. Therefore, the device 100 can acquire the arch length, arch width, and tooth width for each of the plurality of standard preformed orthodontic appliances representing a plurality of preset orthodontic appliances.

[0049] In step S220, the device 100 according to one embodiment acquires the user's oral cavity information.

[0050] In one embodiment, oral information may refer to information about the shape and alignment of the teeth of a user who wishes to wear clear aligners. For example, device 100 may acquire 3D data generated using scan data or CT data of multiple teeth of the user as oral information. Alternatively, device 100 may generate oral information by acquiring scan data or CT data of multiple teeth, or it may acquire oral information from an external device.

[0051] In step S230, according to one embodiment, the device 100 determines one of a plurality of standard preformed orthodontic appliances based on oral information and specification information.

[0052] In one embodiment, the device 100 can determine a standard preformed orthodontic appliance that is expected to be suitable for the user's oral cavity from multiple standard preformed orthodontic appliances by comparing oral information corresponding to the user's tooth shape, dentition, etc. with the specifications of the dental arch length, dental arch width, and tooth width corresponding to multiple standard preformed orthodontic appliances.

[0053] In step S240, a tooth model corresponding to oral cavity information is obtained by the apparatus 100 according to one embodiment.

[0054] In one embodiment, the tooth model is a model corresponding to the user's oral cavity, which may refer to the tooth model in the user's desired state, or the tooth model determined based on the user's oral cavity information.

[0055] In step S250, the apparatus 100 according to one embodiment obtains a clear aligner corresponding to the tooth model by deforming the determined standard preformed aligner to correspond to the tooth model.

[0056] In one embodiment, the device 100 can deform a standard preformed orthodontic appliance selected from a plurality of standard preformed appliances to correspond to a dental model, wherein the plurality of standard preformed orthodontic appliances correspond to a plurality of preformed devices. For example, with the selected standard preformed orthodontic appliance combined with the dental model, the device 100 can perform heat treatment and vacuum treatment on the standard preformed orthodontic appliance by controlling the vacuum heat treatment unit 130. Therefore, the device 100 can separate the clear aligner corresponding to the dental model from the dental model after performing heat treatment and vacuum treatment. In one embodiment, an example of determining one of the plurality of standard preformed orthodontic appliances and an example of obtaining the clear aligner will be achieved by... Figures 3 to 6 Please provide an explanation.

[0057] Figure 3 This is a schematic diagram illustrating an example of how a device 100, according to one embodiment, obtains information about the arch length and arch width of a plurality of standard preformed orthodontic appliances.

[0058] Reference Figure 3 According to one embodiment, the device 100 can acquire arch length 310 and arch width 320, representing specification information, for each of a plurality of standard preformed orthodontic appliances. That is, as Figure 3 As shown, the device 100 can obtain the dental arch length 310 and the dental arch width 320, wherein the dental arch length 310 represents the front-to-back length of the dental arch of each of a plurality of standard preformed orthodontic appliances, and the dental arch width 320 represents the left-to-right width of the dental arch.

[0059] Figure 4 This is a schematic diagram illustrating an example of obtaining tooth width with respect to a plurality of standard preformed orthodontic appliances using a device 100 according to one embodiment.

[0060] Reference Figure 4 According to one embodiment, the apparatus 100 can acquire the tooth width of each segment representing the tooth width. Specifically, the apparatus 100 can acquire the tooth width 410 of a first anterior portion and the tooth width 420 of a second anterior portion corresponding to the anterior portion, and can acquire the tooth width 430 of a posterior portion corresponding to the posterior portion.

[0061] In one embodiment, the width 410 of the first anterior teeth can be the width corresponding to the anterior teeth, namely the central incisors and lateral incisors, and the width 420 of the second anterior teeth can be the width corresponding to the canines located in the third position from the anterior teeth. Furthermore, the width 430 of the posterior teeth can be the width corresponding to any one of the teeth located in the fourth or higher position from the anterior teeth.

[0062] In one embodiment, the anterior tooth width of multiple standard preformed orthodontic appliances can be determined to be between 20 mm and 24 mm, and the posterior tooth width can be determined to be between 22 mm and 25 mm.

[0063] In one embodiment, device 100 can obtain information about the user's dental arch length, dental arch width, and tooth width based on oral information. Device 100 can then determine a corresponding standard preformed orthodontic appliance from a plurality of standard preformed appliances based on this information. That is, device 100 can determine the standard preformed orthodontic appliance that best matches the user's oral information by comparing the user's dental arch length, dental arch width, and tooth width information with the specifications of each of the plurality of standard preformed orthodontic appliances.

[0064] The user's tooth width can include the width of the user's anterior teeth and the width of the user's posterior teeth. That is, the user's tooth width can include the tooth width at the position corresponding to the first anterior tooth width 410, the second anterior tooth width 420, and the posterior tooth width 430 of the above-mentioned multiple standard preformed orthodontic appliances.

[0065] Therefore, the device 100 can determine the most corresponding standard preformed orthodontic appliance by comparing the widths of the user's anterior teeth and posterior teeth with the widths of the first anterior teeth 410, the second anterior teeth 420, and the posterior teeth 430 of the multiple standard preformed orthodontic appliances among one or more standard preformed orthodontic appliances having an arch length 310 and an arch width 320 similar to the user's arch length information and arch width information, respectively.

[0066] Figure 5 This is a schematic diagram illustrating an example of a device 100 according to one embodiment determining one of a plurality of standard preformed orthodontic appliances based on a user's dental arch type.

[0067] Reference Figure 5 In one embodiment, the dental arch type can be one of U-shaped, O-shaped, and V-shaped, wherein U-shaped represents a square shape as a Square type, O-shaped represents an elliptical shape as an Ovoid type, and V-shaped represents a gradually narrowing shape as a Tapered type. According to one embodiment, the device 100 can determine the user's dental arch type as any one of U-shaped, O-shaped, and V-shaped.

[0068] The device 100 can determine one of a plurality of standard preformed orthodontic appliances based on the determined user's dental arch type. For example, the device 100 can determine the standard preformed orthodontic appliance corresponding to the user's dental arch type from at least one or more standard preformed orthodontic appliances corresponding to the user's dental arch length information, user's dental arch width information, and user's tooth width information. Therefore, a standard preformed orthodontic appliance that uses information related to the user's dental arch type together with oral cavity information can be determined as the standard preformed orthodontic appliance corresponding to the user.

[0069] Figure 6 This is a schematic diagram illustrating an example of obtaining a transparent orthodontic appliance 630 from a three-dimensional shape according to one embodiment.

[0070] Reference Figure 6According to one embodiment, the apparatus 100 can modify one of a plurality of standard preformed orthodontic appliances representing a preformed device to correspond to a user's dental model 610. The user's dental model 610 is generated in a shape identical to the shape of teeth based on the user's oral structure. For example, the user's oral structure can be scanned using a 3D scanner, and the user's dental model 610 can be generated based on the scan data. This can be done using a 3D printer. The user's dental model 610 can be output by outputting the scan data acquired using a 3D scanner through a 3D printer.

[0071] In one embodiment, the device 100 can control the vacuum heat treatment unit 130 to deform a standard preformed orthodontic appliance 620, which is determined to be one of a plurality of standard preformed orthodontic appliances, into a shape corresponding to the user's dental model 610. Therefore, the device 100 can obtain a clear aligner 630 formed by deforming the determined standard preformed orthodontic appliance 620.

[0072] In one embodiment, the device 100 can generate 3D images based on statistical information and output multiple standard preformed orthodontic appliances via a 3D printer. For example, the shapes of the multiple standard preformed orthodontic appliances are formed based on the 3D shapes of multiple standard dental models, which are determined based on statistical information. The shape of any one of the multiple standard preformed orthodontic appliances can be a shape corresponding to any one of the multiple standard dental models.

[0073] For example, a standard dental model can be a dental model obtained based on statistical information about the size and specifications of Asian teeth. The shape of a standard preformed orthodontic appliance can be a shape combined with each of one or more standard dental models, which represent various sizes, heights, and other features classified according to the standard size or specification range of Asian teeth. For example, Asian teeth can be classified according to their size and specifications, and multiple standard preformed orthodontic appliances corresponding to shapes related to the morphology of a predetermined number, such as nine, standard dental models can be obtained and combined using dimensions, heights, etc.

[0074] In one embodiment, the internal space of a standard preformed orthodontic appliance can be configured to define a gap that is maintained even after a standard dental model is combined with the standard preformed orthodontic appliance.

[0075] Reference Figure 6 This confirms an example of combining the determined standard preformed orthodontic appliance 620 with a user's dental model 610 corresponding to the user's oral information. For example... Figure 6 As shown in the first step, the determined standard preformed orthodontic appliance 620 can be combined with the user's dental model 610.

[0076] Therefore, the device 100 can control the vacuum heat treatment unit 130 to perform heat treatment and vacuum treatment on the determined standard preformed orthodontic appliance 620 while it is combined with the user's dental model 610, thereby obtaining a clear orthodontic appliance 630 corresponding to the user's oral cavity information. That is, the vacuum heat treatment unit 130 can separate the determined standard preformed orthodontic appliance 620 from the user's dental model 610 after performing heat treatment and vacuum treatment on it. Therefore, a clear orthodontic appliance 630 that has been deformed into a shape corresponding to the user's dental model 610 by heat treatment and vacuum treatment of the determined standard preformed orthodontic appliance 620 can be obtained.

[0077] In one embodiment, the internal space representing the area where a standard preformed orthodontic appliance is combined with a dental model can be configured to define a gap that is maintained even after combination with the standard dental model. For example, the shape of the standard preformed orthodontic appliance can be determined to be a predetermined size larger than the shape of the standard dental model generated according to a standard specification range, in order to define the gap. That is, a plurality of standard preformed orthodontic appliances corresponding to a predetermined number (e.g., nine) can have a shape in which the internal space of each standard preformed orthodontic appliance is configured to define a gap exceeding the shape region of each of the plurality of standard dental models.

[0078] Therefore, heat treatment and vacuum treatment can be performed while a standard preformed orthodontic appliance 620, which is identified as one of a plurality of standard preformed appliances, is combined with a user tooth model 610 corresponding to the user's oral information. Thus, as... Figure 6 As shown in the final step, a clear aligner 630 corresponding to the shape of the user's dental model 610 can be obtained.

[0079] According to the present invention, since heat treatment and vacuum treatment are performed by combining a predetermined number of standard preformed orthodontic appliances with the user's dental model 610, thickness variations that may occur during heat treatment can be prevented when obtaining the clear orthodontic appliance 630 using existing clear sheet materials. That is, according to the present invention, since a 3D model can be obtained from a 3D model by utilizing multiple standard preformed orthodontic appliances representing the preformed device, it has the advantage of maintaining a uniform thickness.

[0080] Furthermore, when using existing transparent sheets to obtain the transparent orthodontic appliance 630, it is necessary to cut and polish a portion of the sheet; in contrast, according to the present invention, since the determined standard preformed orthodontic appliance 620 exists in a 3D shape corresponding to the transparent orthodontic appliance 630, it has the advantage of not requiring a polishing process.
