From the perspective of preventing or consolidating the treatment effect of malocclusion, improving poor oral hygiene habits is of great significance in blocking the treatment of malocclusion. Invisible aligners are increasingly accepted and used by users due to their advantages of aesthetics, hygiene, ease of removal and insertion, and better orthodontic results.

[0003] Existing invisible orthodontic appliances typically feature raised structures on the tongue muscle training components, encouraging users to actively touch these structures to train their tongue muscles. However, the experience and enjoyment of touching these raised structures is poor, failing to motivate users and resulting in ineffective tongue muscle training. Summary of the Invention

[0036] In the various illustrations of this utility model, for ease of illustration, some dimensions of the structure or part may be exaggerated relative to other structures or parts. Therefore, they are only used to illustrate the basic structure of the subject matter of this utility model.

[0037] Reference Figure 1 As shown, an invisible aligner includes a shell-shaped body 10 and a tongue muscle training component 20. In this embodiment, all parts of the invisible aligner (e.g., the shell-shaped body 10 and the tongue muscle training component 20) are made of transparent or translucent polymer materials, making the aligner invisible. The tongue muscle training component 20 is connected to the shell-shaped body 10 and can provide tongue muscle training (e.g., tongue curling training, N-point vocalization training) to the user in the oral cavity after the shell-shaped body 10 is worn on the teeth.

[0038] In some embodiments, the shell-like body 10 has a cavity for accommodating a plurality of maxillary teeth. In this embodiment, the shell-like body 10 is configured as a shell-like structure capable of enclosing teeth (e.g., maxillary teeth).

[0039] In some embodiments, the tongue muscle training device 20 is connected to the lingual gingival margin or adjacent to the gingival margin of the shell-shaped body 10. In this embodiment, connecting the tongue muscle training device 20 to the lingual gingival margin or adjacent to the gingival margin of the shell-shaped body 10 reduces the feeling of a foreign object in the user's mouth, making it more comfortable to wear. Furthermore, it prevents the tongue from sinking down to find a comfortable position after wearing clear aligners. Preferably, the lingual gingival margin location is at 1 / 3 to 1 / 2 of the total crown height from the gingival margin.

[0040] In some embodiments, the tongue muscle training device 20 has a sensing cavity 201 and a sensing port 202 that exposes the sensing cavity 201. In this embodiment, the sensing port 202 is open and can expose the sensing cavity 201 to the outside, that is, the external environment can be connected to the sensing cavity 201 through the sensing port 202.

[0041] In some embodiments, the sensing opening 202 is located on the lingual side of the tongue muscle training device 20. In this embodiment, the tongue muscle training device 20 also has a palatal side opposite to the lingual side. The lingual side of the tongue muscle training device 20 refers to the side of the tongue muscle training device 20 facing the tongue after the invisible aligner is worn on the upper teeth. At this time, the palatal side refers to the side of the tongue muscle training device 20 facing the hard palate (e.g., the palatal mucosa). Because the sensing opening 202 is located on the lingual side of the tongue muscle training device 20, the user's tongue can easily touch the sensing opening 202 and extend into the sensing cavity 201 through the sensing opening 202.

[0042] The tongue muscle training device 20 is provided with a sensing cavity 201 and a sensing port 202 that exposes the sensing cavity 201. The sensing port 202 is located on the side of the tongue muscle training device 20 facing the tongue. The user's tongue completes the tongue muscle training by touching the sensing port 202 and partially extending into the sensing cavity 201. The experience and fun are good, which can stimulate the user's training enthusiasm and improve the effect of tongue muscle training.

[0043] In some embodiments, the shell-like body 10 has a geometric structure that gradually aligns the teeth from their initial position to the target orthodontic position. In this embodiment, when the invisible aligner is used for tongue muscle training (e.g., tongue curling training, N-point vocalization training) with the tongue muscle training component 20, it can simultaneously perform tooth orthodontic treatment, thereby achieving multiple functions with a single aligner without the need for multiple aligners for individual treatment.

[0044] Specifically, when a user wears an invisible aligner, the shell-shaped body 10 not only serves to enclose the teeth, but also to correct them, that is, to gradually reposition the teeth from their initial position to their target position. This not only improves the efficiency of the treatment at each stage, but also improves the overall treatment efficiency.

[0045] In other embodiments, the shell-like body 10 may only serve to wrap around the teeth and does not have an orthodontic effect on the teeth. This arrangement can enhance the user's wearing comfort, only produce the effect of training the tongue muscles, and does not have an orthodontic effect on the teeth. The orthodontic treatment is more targeted, while reducing the discomfort caused by the shell-like body 10 to the teeth.

[0046] For example, an orthodontic kit consisting of multiple clear aligners can be used for single-jaw orthodontic treatment, such as maxillary orthodontic treatment. During the treatment process, multiple clear aligners are used to gradually reposition the teeth from their initial position to their target position. For example, when multiple clear aligners are worn on the maxillary teeth, the tongue muscle training piece 20 can provide tongue muscle training for the user. At the same time, the shell-shaped body 10 has a geometric structure that allows the teeth to be gradually repositioned from their initial position to the target orthodontic position, so that the user's maxillary teeth can be treated while the tongue muscles are being trained, achieving synchronous treatment of the tongue and teeth and improving treatment efficiency.

[0047] In some embodiments, the shell-shaped body 10 and the tongue muscle training component 20 are integrally molded. In this embodiment, the shell-shaped body 10 and the tongue muscle training component 20 are integrally molded. This can be achieved by molding the shell-shaped body 10 and the tongue muscle training component 20 as a single piece using a thermoforming process, followed by cutting according to actual treatment needs, or by directly 3D printing. When using an integrally molded structure, the manufacturing process is simple, it is convenient for the user to wear, and the tight connection between the shell-shaped body 10 and the tongue muscle training component 20 ensures high wearing safety, preventing unnecessary injury caused by accidental ingestion due to a loose connection between the shell-shaped body 10 and the tongue muscle training component 20.

[0048] In other embodiments, the shell-shaped body 10 and the tongue muscle training component 20 are separate molding structures. In this embodiment, the shell-shaped body 10 and the tongue muscle training component 20 are separate molding structures, which can be separately connected and molded through adhesive, magnetic attraction, snap-fit, or other structures. The separate molding structure facilitates installation, allowing users to select shell-shaped body 10 and tongue muscle training component 20 that best suit the different orthodontic effects produced in their mouths, thus providing personalized treatment.

[0049] Reference Figure 2 and Figure 3 As shown, the tongue muscle training device 20 includes a sensing structure 203 forming a sensing cavity 201 and a support portion 204 connecting the sensing structure 203. The support portion 204 has opposing lingual surfaces 2041 and palatal surfaces 2042. In this embodiment, the sensing cavity 201 is formed by the sensing structure 203. When the invisible aligner is worn on the upper teeth, the side of the support portion 204 facing the tongue is the lingual surface 2041, and the side of the support portion 204 facing the palatal mucosa is the palatal surface 2042.

[0050] In some embodiments, at least a portion of the sensing structure 203 protrudes from the tongue side surface 2041. In this embodiment, as... Figure 2 The sensory structure 203 (e.g., all of the sensory structures 203) protrudes from the tongue side 2041. At this time, the sensory mouth 202 and the sensory cavity 201 also protrude from the tongue side 2041, making it easier for the user's tongue to touch the sensory mouth 202 and the sensory cavity 201, thereby facilitating tongue muscle training.

[0051] In other embodiments, at least a portion of the sensing structure 203 protrudes from the palatal side surface 2042. In this embodiment, as... Figure 3When the sensory structure 203 (e.g., all of the sensory structures 203) protrudes from the palatal side surface 2042, the sensory opening 202 is flush with the lingual side surface 2041. That is, the sensory cavity 201 is formed by the sensory structure 203 recessed into the lingual side surface 2041, meaning the sensory cavity 201 protrudes from the palatal side surface 2042. Therefore, the lingual side surface 2041 of the support portion 204 is a flat surface, reducing the sensation of a foreign object caused by the user's tongue touching the protruding sensory structure 203 after wearing the invisible orthodontic appliance.

[0052] Figure 2 and Figure 3 The two implementation methods provided are preferably manufactured by integral molding (e.g., hot pressing or 3D printing).

[0053] Reference Figure 4 and Figure 5 As shown, the tongue muscle training device includes a sensing structure 203 and a support portion 204. The sensing structure 203 is configured as a hole structure that at least partially penetrates the support portion 204. In this embodiment, the hole structure can be a blind hole or a through hole, that is, a blind hole that partially penetrates the support portion 204 or a through hole that completely penetrates the support portion 204. The sensing cavity 201 is formed within the corresponding hole structure (i.e., a blind hole or a through hole).

[0054] In some embodiments, the sensing structure 203 is configured as a perforated structure penetrating the support portion 204 to form a somatosensory closed loop between the tongue and the oral mucosa when the invisible aligner is worn on the maxillary teeth. In this embodiment, as Figure 4 The perforated structure (i.e., the sensing structure 203) is a through hole that completely penetrates the support portion 204. When the tongue extends from the sensing opening 202 into the sensing cavity 201, it can pass through the sensing cavity 201 and contact the palatal mucosa. Therefore, when the user uses the sensing structure 203 for tongue muscle training, the tongue can pass through the sensing cavity 201 and contact the palatal mucosa, forming a somatosensory closed loop (i.e., between the tongue and the oral mucosa), further enhancing the experience and enjoyment. Furthermore, the tongue-side surface 2041 of the support portion 204 is flat, which reduces the sensation of the user's tongue touching the protruding sensing structure 203 and causing a foreign body sensation after the user wears the invisible orthodontic appliance.

[0055] In other embodiments, the sensing structure 203 is configured as a hole structure that partially penetrates the support portion 204. In this embodiment, as... Figure 5 The hole structure (i.e., the sensing structure 203) is a blind hole that partially penetrates the support portion 204. The lingual side 2041 of the support portion 204 is a flat surface, which reduces the sensation of a foreign object caused by the user's tongue touching the raised sensing structure 203 after the user wears the invisible aligner.

[0056] Figure 4 and Figure 5In both embodiments provided, the hole structure can be formed on the support portion 204 through secondary processing (e.g., drilling).

[0057] For example, when the invisible aligner is worn on the upper teeth, the distance between the support portion 204 and the palatal mucosa is no more than 2 mm.

[0058] When the sensory structure 203 protrudes from the tongue side 2041 (as shown in the image) Figure 2 ) or partially penetrate the load-bearing part (such as Figure 5 When the bearing part 204 is in contact with the palatal mucosa for a long time, there is a gap between the bearing part 204 and the palatal mucosa (for example, the gap is less than 2 mm), which can prevent the bearing part 204 from being in sealed contact with the palatal mucosa for a long time, which would lead to the growth of bacteria.

[0059] When the sensory structure 203 protrudes from the palatal side 2042 (as shown in the image) Figure 3 When the bearing part 204 is in contact with the palatal mucosa, there is a sufficient gap (e.g., a gap of 2 mm) between the bearing part 204 and the palatal mucosa, which can prevent the sensing structure 203 from directly contacting the palatal mucosa and causing discomfort, thus ensuring wearing comfort.

[0060] When the sensing structure 203 completely penetrates the supporting part 204 (e.g.) Figure 4 The distance between the bearing portion 204 and the palatal mucosa is small enough (e.g., less than 2 mm) to allow the tongue to smoothly contact the palatal mucosa after passing through the sensing cavity 201, thereby forming a somatosensory closed loop.

[0061] In some embodiments, the curvature of the support portion 204 matches the curvature of the palate. In this embodiment, it is preferable that the curvature of the support portion 204 matches the curvature of the palate. When the support portion 204 is fitted to the palate (e.g.) Figure 2 The sensory structure 203 protrudes from the lateral surface of the tongue 204. Figure 4 The sensing structure 203 penetrates the entire bearing part 204, or Figure 5 When the sensing structure 203 partially penetrates the support portion 204, it can save space in the oral cavity and make wearing it more comfortable. When the support portion 204 is spaced apart from the hard palate (e.g., ...), it can save space in the oral cavity and make wearing it more comfortable. Figure 3 The sensory structure 203 protrudes from the palatal side (2042), which also makes the patient more comfortable to wear and saves space in the oral cavity.

[0062] In some embodiments, the area of ​​the sensing port 202 is not less than 0.2 cm². 2 and no larger than 2cm 2 In this embodiment, the area of ​​the sensing port 202 is greater than or equal to 0.2 cm². 2 At that time, the sensing opening 202 is designed to be easily perceived by the user's tongue tissue. The area of ​​the sensing opening 202 is less than or equal to 4 cm². 2 (e.g., 2cm)2 This design avoids the problem of an excessively large area affecting the accuracy of the training position, allowing users to precisely train their tongue muscles and achieve the desired training effect.

[0063] In some embodiments, the cross-sectional area of ​​the sensing structure 203 is not less than 0.2 cm². 2 and no larger than 2cm 2 In this embodiment, the cross-sectional area of ​​the sensing structure 203 is greater than or equal to 0.2 cm². 2 At the same time, ensure that the tongue can be inserted into the sensory cavity 201. The cross-sectional area of ​​the sensory structure 203 is less than or equal to 4 cm². 2 (e.g., 2cm) 2 ), just enough to accommodate the tip of the tongue (e.g. Figure 3 and Figure 5 The implementation shown is beneficial for tongue muscle training (such as N-point vocalization training and tongue curling training), increasing the experience and fun.

[0064] In some embodiments, the inner diameter of the sensing structure 203 is not less than 3 mm. In this embodiment, when the sensing structure 203 completely penetrates the bearing portion 204 (e.g. Figure 4 The inner diameter of the sensing structure 203 (i.e., the perforation structure) is greater than or equal to 3 mm, so that the tongue can smoothly pass through the sensing cavity 201 to touch the oral mucosa tissue (i.e., palatal mucosa tissue) covered by the support part 204 while sensing the sensing cavity 201. This allows for specific training of the tongue and the formation of a somatosensory closed loop (between the tongue and the oral mucosa), increasing the experience and enjoyment. Figure 2 , Figure 3 and Figure 5 In the embodiment shown, the inner diameter of the sensing structure 203 is greater than or equal to 3 mm, which facilitates the tongue to be inserted into the sensing cavity 201.

[0065] In addition, when the cross-section of the sensing structure 203 (e.g., the hole structure) is irregular, the maximum inner diameter needs to be greater than or equal to 3 mm.

[0066] Purely as a non-limiting example, the shell-like body 10 has an anterior tooth region 101 and a posterior tooth region 102. In this embodiment, as... Figure 1 The shell-shaped body 10 has a cavity for accommodating several maxillary teeth, dividing the cavity into anterior tooth region 101 and posterior tooth region 102. Furthermore, the shell-shaped body 10 has two anterior tooth regions 101 and two posterior tooth regions 102 located on the left and right sides. The anterior tooth region 101 can be used to accommodate the maxillary central incisors, lateral incisors, and canines, while the posterior tooth region 102 can be used to accommodate the maxillary first premolar, second premolar, first molar, second molar, and third molar.

[0067] In some embodiments, the support portion 204 is connected to the anterior tooth region 101 and / or the posterior tooth region 102. In this embodiment, the support portion 204 is connected to at least one anterior tooth region 101 and / or at least one posterior tooth region 102, that is, it can be connected to at least one of the left and right anterior tooth regions 101 and at least one of the left and right posterior tooth regions 102. The sensing structure 203 is fixed to the shell-shaped body 10 by the support portion 204, and the sensing structure 203 and the support portion 204 are either integrally formed or separately formed as described above. The connection position of the tongue muscle training component 20 can be determined according to the different types of tongue training (e.g., training of N-point vocalization position, tongue curling training), that is, the connection position of the support portion 204 (e.g., anterior tooth region 101 and / or posterior tooth region 102) can be determined.

[0068] For example, the distance D1 between the center of the sensing opening 202 and the lingual gingival margin of the anterior tooth region 101 is between 3 mm and 15 mm. Figure 1 The support portion 204 is connected to the anterior tooth regions 101 on both the left and right sides, thereby training the N-point vocalization position. Since the N-point vocalization position is different for each person, the distance D1 between the center of the sensing mouth 202 and the lingual gingival margin of the anterior tooth region 101 is set to be between 3mm and 15mm, which can meet the needs of the N-point vocalization position for all people.

[0069] Preferably, the distance D1 between the center of the sensing opening 202 and the lingual gingival margin of the anterior tooth region 101 is between 5mm and 8mm. In this embodiment, the distance D1 between the center of the sensing opening 202 and the lingual gingival margin of the anterior tooth region 101 is set to be between 5mm and 8mm, which is close to the requirement of the N-point vocalization position of the general population.

[0070] In some embodiments, the minimum distance D4 between the edge of the sensing port 202 and the edge of the bearing portion 204 is not less than 1 mm. In this embodiment, the edge of the sensing port 202 (e.g. Figure 1 The edge of the sensing port 202 near the free end 2044 and the edge of the bearing portion 204 (e.g.) Figure 1 The minimum distance between the free end 2044 and the sensor 202 is greater than or equal to 1 mm, ensuring the stability of the sensor 202 during molding (i.e., not easily broken). Moreover, compared to the solution where "the minimum distance D4 between the edge of the sensor 202 and the edge of the support part 204 is less than 1 mm", this allows the tongue to clearly perceive the complete shape of the sensor 202 when it touches the sensor 202.

[0071] Purely as a non-limiting example, the support portion 204 has a fixed end 2043 connected to the anterior tooth region 101 and a free end 2044 away from the fixed end 2043. In this embodiment, as... Figure 1Since the support portion 204 is connected to the left and right anterior tooth regions 101, the fixed end 2043 is the end of the support portion 204 that extends along the curvature of the palate and is close to the labial side (e.g., at the central incisor), and the free end 2044 is the end of the support portion 204 that extends along the curvature of the palate and is away from the labial side. When training the N-point vocalization position with the support portion 204 connected to the left and right anterior tooth regions 101, the support portion 204 extends from the fixed end 2043 toward the free end 2044, that is, from the lingual gingival margin of the anterior tooth region 101 toward the palate, so that the support portion 204 covers at least part of the palate (e.g., the hard palate).

[0072] For example, the distance D2 between the free end 2044 and the lingual gingival margin of the anterior tooth region 101 is not less than 5 mm. In this embodiment, as... Figure 1 When the support portion 204 is connected to the lingual gingival margin, the distance D2 between the free end 2044 and the lingual gingival margin of the anterior tooth region 101 (i.e., the distance between the free end 2044 and the fixed end 2043) is not less than 5mm. This allows for minimizing the length of the support portion 204 (i.e., the distance D2 between the free end 2044 and the lingual gingival margin of the anterior tooth region 101) under the premise of processing and training, thus saving oral cavity space. For example, when the distance D2 between the free end 2044 and the lingual gingival margin of the anterior tooth region 101 is 5mm, the radius of the sensing port 202 is 1mm, and the distance between the edge of the sensing port 202 near the free end 2044 and the edge of the support portion 204 (i.e., at the free end 2044) is 1mm, then the distance D1 between the center of the sensing port 202 and the lingual gingival margin of the anterior tooth region 101 is 3mm (i.e., the minimum distance for N-point vocalization training), thereby meeting the requirements of processing and training.

[0073] In some embodiments, the tongue muscle training device 20 has at least one sensing opening 202, the center of which is located at the top of the palate.

[0074] When the tongue muscle training piece 20 has a sensing opening 202, the support part 204 is connected to the anterior tooth area 101 (e.g., the left and right anterior tooth areas 101). At this time, the center of the sensing opening 202 is located at the top of the hard palate, thereby performing tongue curling training.

[0075] When the tongue muscle training device 20 has two sensing ports 202, the bearing part 204 is connected to the anterior tooth area 101 (e.g., the left and right anterior tooth areas 101) and the posterior tooth area 102 (e.g., one of the left and right posterior tooth areas 102). At this time, the center of the sensing port 202 corresponding to the anterior tooth area 101 is located at the top of the palate, so tongue rolling training can be performed.

[0076] like Figure 6When the tongue muscle training component 20 has three sensing ports 202, the support portion 204 is connected to the anterior tooth region 101 (e.g., the left and right anterior tooth regions 101) and the posterior tooth region 102 (e.g., the left and right posterior tooth regions 102). At this time, the center of the sensing port 202 corresponding to the anterior tooth region 101 is located at the top of the hard palate, and tongue curling training can be performed. In addition, this method only requires one support portion 204 to form multiple sensing ports 202.

[0077] Reference Figure 7 As shown, in some embodiments, the tongue muscle training device 20 has at least one sensing port 202, and the distance D3 between the center of the at least one sensing port 202 and the lingual gingival margin of the posterior tooth region 102 is not less than 3 mm.

[0078] When the tongue muscle training piece 20 has a sensing opening 202, the bearing part 204 is connected to the posterior tooth area 102 (e.g., one of the left and right posterior tooth areas 102). At this time, the distance D3 between the center of the sensing opening 202 and the lingual gingival margin of the corresponding posterior tooth area 102 is not less than 3mm, thereby performing tongue rolling training.

[0079] like Figure 7 When the tongue muscle training device 20 has two sensing ports 202, the supporting part 204 is connected to the left and right posterior tooth areas 102 respectively. That is, the tongue muscle training device 20 has a supporting part 204 that corresponds one-to-one with the sensing ports 202 (that is, the number of supporting parts 204 is two). At this time, the distance D3 between the center of the two sensing ports 202 and the lingual gingival margin of the corresponding posterior tooth area 102 is not less than 3mm, so as to carry out tongue rolling training.

[0080] Alternatively, when the tongue muscle training component 20 has two sensing ports 202, the supporting part 204 is connected to the anterior tooth region 101 (e.g., the left and right anterior tooth regions 101) and the posterior tooth region 102 (e.g., one of the left and right posterior tooth regions 102). The center of the sensing port 202 corresponding to the anterior tooth region 101 is located at the top of the hard palate, and the distance D3 between the center of the sensing port 202 corresponding to the posterior tooth region 102 and the lingual gingival margin of the posterior tooth region 102 is not less than 3 mm, thereby enabling multiple (i.e., two) tongue curling exercises. Of course, the distance D1 between the center of the aforementioned "sensing port 202 corresponding to the anterior tooth region 101" and the lingual gingival margin of the anterior tooth region 101 can also be set to be between 3 mm and 15 mm (or preferably between 5 mm and 8 mm), which can meet the needs of the N-point vocalization position, thereby enabling simultaneous N-point vocalization position training and tongue curling training.

[0081] like Figure 6When the tongue muscle training component 20 has three sensing ports 202, the supporting part 204 is connected to the anterior tooth region 101 (e.g., the left and right anterior tooth regions 101) and the posterior tooth region 102 (e.g., the left and right posterior tooth regions 102). At this time, the center of one of the sensing ports 202 (i.e., the sensing port 202 corresponding to the anterior tooth region 101) is located at the top of the hard palate, and the distance D3 between the center of the other two sensing ports 202 and the lingual gingival margin of the corresponding posterior tooth region 102 is not less than 3mm, thereby performing multiple (i.e., three) tongue curling exercises. Similarly, the distance D1 between the center of the aforementioned "sensing port 202 corresponding to the anterior tooth region 101" and the lingual gingival margin of the anterior tooth region 101 can also be set between 3mm and 15mm (or preferably between 5mm and 8mm), which can meet the needs of the N-point vocalization position, thereby performing N-point vocalization position training and tongue curling training simultaneously.
