Abstract
Description
Technical Field
[0001] This application relates to the field of orthodontics in oral clinical practice, and particularly to a shell-shaped dental instrument. Background Art
[0002] Orthodontics is a comprehensive treatment method for dental and maxillofacial deformities, mainly for correcting dental and maxillofacial deformities. Its main purpose is to treat abnormal conditions such as irregular teeth, tooth gaps, protruding teeth, and jaw development. Through orthodontic treatment, teeth can become complete and beautiful, achieving the purpose of coordinated balance of the dentognathic system. Since multiple orthodontic treatment methods may be combined in orthodontic treatment planning, such as arch expansion, arch constriction, and distal movement of molars, if orthodontists ignore the factor of muscle function during clinical diagnosis and treatment, due to the imbalance of labial, buccal, and lingual muscle forces caused by bad tongue habits or abnormal tongue positions, and this unbalanced muscle force may cause the teeth after orthodontics to not be able to stably occlude in the accurate position, resulting in the recurrence of malocclusion deformities, so that repeated orthodontic treatments may be required, seriously affecting the orthodontic efficiency.
[0003] There is a current solution to first perform tongue muscle force treatment in the early stage of orthodontic treatment and then perform traditional orthodontic treatment after the tongue muscle force becomes normal. However, the orthodontic treatment time is relatively long, and long-term wearing is not beneficial to the comfort and experience of patients. Therefore, if a treatment device that can perform tooth orthodontics and tongue training simultaneously can be designed, the above problems can be successfully solved.
[0004] In this application, the "jaw" in "malocclusion", "open bite", "overbite", "occlusal plane", etc. is "occlusion" (hé). This character is a rare character, and since it is not available in the character library of general input methods, it is often written as "jaw" in daily life and on the Internet. For the convenience of reading in this article, it is also written as "jaw". Utility Model Content
[0005] The purpose of this application is to provide a shell-shaped dental instrument, which can achieve simultaneous tooth orthodontics and tongue training, reduce the possibility of orthodontic recurrence, accelerate the overall orthodontic speed, shorten the overall orthodontic cycle, and improve the user experience.
[0006] To solve the above technical problems, an embodiment of this application provides a shell-shaped dental instrument, including: a shell-shaped body provided with a plurality of tooth receiving cavities, at least one arch portion is extended and provided on the lingual side of the posterior tooth area of the shell-shaped body, the arch portion at least partially spans the arch width of the shell-shaped body, and the arch portion is designed to provide arch expansion force, arch constriction force, or auxiliary resistance force for the distal movement of posterior teeth to at least some teeth in the posterior tooth area, wherein, a tongue guiding structure for guiding the tongue to lick is provided on the arch portion.
[0007] The shell-shaped dental device in the embodiment of the present application, by setting a tongue guide structure on the dental arch, allows different functional devices to be used at the same time. When the user wears the shell-shaped dental device in the present application, tongue training and tooth orthodontics can be carried out at the same time, reducing the possibility of orthodontic recurrence and speeding up the overall correction speed. In addition, by presetting the shape, position, and number of the tongue guide structure, a variety of flexible training of the tongue can be achieved, so that doctors can design tongue training programs for patients more flexibly, increase the fun of the tongue training process, and increase patient compliance, which is especially conducive to promotion among pediatric patients.
[0008] In some embodiments, the tongue guiding structure includes: a through hole portion, or a tongue protrusion protruding away from the palate. Different forms of the tongue guiding structure can be achieved by protrusions or through holes, and both can generate stimulation and guide the user to lick.
[0009] In some embodiments, the through hole is filled with: a single-layer solid block formed by at least one of sugar, calcium, and milk, or a multi-layer structure formed by multiple of them; or the tongue protrusion is: a single-layer solid block formed by at least one of sugar, calcium, and milk, or a multi-layer structure formed by multiple of them. Further limiting the through hole and the tongue protrusion, both can be implemented in combination with a sweet or milky slow-release structure, so as to induce the user to lick more through the taste, so as to enhance the training effect.
[0010] In some embodiments, the side of the tongue protrusion away from the palate is a smooth arc surface. The outer surface of the tongue protrusion is further limited to a smooth arc surface to prevent the thorns from damaging the tongue and other soft tissues of the oral cavity when contacting the tongue protrusion, and reduce the foreign body sensation when the shell-shaped dental appliance is worn.
[0011] In some embodiments, there are multiple tongue guide structures, and at least two of the multiple tongue guide structures have different sizes. It is limited to setting multiple tongue guide structures in the shell-shaped dental instrument, so as to guide the tongue to lick multiple target positions, increase the range of tongue movement during tongue muscle training, and enhance the tongue training effect. In addition, since different sizes of tongue guide structures will cause different licking difficulties, different sizes of tongue guide structures are set to combine tongue training of different difficulties, so as to enrich the tongue training program.
[0012] In some embodiments, the size is characterized by at least one of the following: the area of the projection pattern of the tongue guide structure on the dental arch portion, the maximum width of the projection pattern of the tongue guide structure on the dental arch portion, the surface area of the tongue guide structure facing the tongue side, and the height of the tongue guide structure on the dental arch portion. By setting tongue guide structures with different parameters, tongue guide structures of different sizes can be realized, the variation possibilities of the tongue guide structure are increased, and the morphological diversity of the tongue guide structure is increased.
[0013] In some embodiments, there are multiple tongue guide structures, at least one of which is located at or near the midline of the palate, and at least one is located near the shell-like body. In some embodiments where multiple tongue guide structures are provided, some are located in the middle and some are located at the edge, and licking targets with different distances are combined to increase the difficulty of training, so as to enrich the tongue training program and adapt to different application scenarios.
[0014] In some embodiments, the size of the tongue guide structure located near the midline of the palate is larger than that of the tongue guide structure located near the shell-like body. In some embodiments where multiple tongue guide structures are provided, the size of the middle tongue guide structure is larger than that of the surrounding tongue guide structures, and licking targets of different difficulty levels are combined to enrich the tongue training program and adapt to different application scenarios.
[0015] In some embodiments, the shell-shaped dental appliance includes a plurality of tongue guide structures arranged along the midline of the palate. The tongue guide structures defined near the midline of the palate are arranged sagittally forward and backward. Since the more backward the position in the sagittal direction is, the more difficult it is to lick, and the stronger the tongue muscle strength required, the tongue guide structures arranged sagittally forward and backward can guide the patient to gradually train the tongue muscles to improve the training effect.
[0016] In some embodiments, the plurality of tongue guide structures are arranged at intervals, and the interval between two adjacent tongue guide structures is greater than 0 and less than or equal to 5 mm. The tongue guide structures arranged sagittally forward and backward are arranged at intervals of a certain distance to avoid excessive intervals that reduce the user's interest in licking.
[0017] In some embodiments, the maximum width of the projection pattern of the tongue guide structure on the dental arch is 1-10 mm. The size of the tongue guide structure is limited to avoid a tongue guide structure that is too small, which makes licking too difficult and has no induction effect, and a tongue guide structure that is too large, which occupies too much space in the oral cavity and affects the wearing experience.
[0018] In some embodiments, when the dental arch portion is designed to provide an expansion force, the dental arch portion includes a flexible connection portion for connecting the shell-like body and the dental arch portion body, and the flexible connection portion absorbs at least a portion of the deformation of the end of the dental arch portion when the dental arch portion is deformed. It is further defined that in the expansion scenario, the dental arch portion is flexibly connected to the shell-like body so as to absorb the retraction force caused by the compression deformation of the dental arch portion when the tongue guide structure is licked.
[0019] In some embodiments, the shell-shaped body, the dental arch portion and the tongue guide structure are integrally formed. The shell-shaped dental device in the present application is manufactured by integrally forming, which reduces the manufacturing cost and improves the integrity of the shell-shaped dental device.
[0020] In some embodiments, when the dental arch portion is designed to provide an expansion force, the side of the dental arch portion close to the palate directly or indirectly contacts the hard palate portion to absorb the reaction force of the dental arch portion when worn, and the reaction force comes from the force applied by the shell-like body to one or more teeth of the patient. Further limited to the expansion scenario, the dental arch portion can absorb the reaction force by direct or indirect contact with the hard palate portion to provide auxiliary force for expansion or other forces applied to the teeth.

[0035] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.
[0036] The "anterior tooth area" and "posterior tooth area" mentioned in various embodiments of the present application are defined according to the classification of teeth in the second edition of "Introduction to Stomatology" published by Peking University Medical Press, pages 36-38. The posterior tooth area includes premolars and molars, which are shown as teeth 4-8 in the FDI marking method. The anterior tooth area is shown as teeth 1-3 in the FDI marking method, and the teeth in the anterior tooth area include central incisors, lateral incisors and canines.
[0037] The "jaw plane" mentioned in each embodiment of the present application is obtained according to the definition and confirmation method on page 83 of the 6th edition of "Orthodontics". One method is to connect the occlusal midpoint of the first permanent molar and the midpoint between the upper and lower central incisors (1 / 2 of the overbite or open bite); the other method is obtained by equally dividing the jaw contact points of the posterior teeth, and the jaw contact points of the first permanent molar and the first deciduous molar or the first premolar are often used.
[0038] In order to solve the above-mentioned technical problems, the inventors of the present application have conducted in-depth research on oral correction devices and proposed a dental instrument that can implement invisible correction, dental arch correction, tongue muscle training and other programs at the same time, so that doctors can combine multifunctional orthodontics when designing treatment plans, so as to combine different functional devices and shorten the overall orthodontic cycle.
[0039] In one embodiment of the present application, a shell-shaped dental instrument is provided, specifically comprising: a shell-shaped body provided with a plurality of tooth receiving cavities, at least one dental arch portion extending from the lingual side of the posterior tooth area of the shell-shaped body, the dental arch portion at least partially spanning the dental arch width of the shell-shaped body, the dental arch portion being designed to provide an expansion force and a contraction force to at least part of the teeth in the posterior tooth area, or to provide an auxiliary support force for the distal displacement of the posterior teeth, wherein a tongue guide structure for guiding the tongue to lick is provided on the dental arch portion. By providing a tongue guide structure on the dental arch portion, different functional devices can be used at the same time, and when the user wears the shell-shaped dental instrument in the present application, tongue training and tooth orthodontics can be carried out at the same time, thereby accelerating the correction efficiency. In addition, by presetting the shape, position, and number of the tongue guide structure, a variety of flexible training of the tongue can be achieved, so that the doctor can design a tongue training program for the patient more flexibly, and also increase the fun of the tongue training process, increase the compliance of the patient, and is particularly conducive to promotion among pediatric patients.
[0040] The implementation details of the shell-shaped dental apparatus of this embodiment are described in detail below. The following contents are only provided for the convenience of understanding and are not necessary for implementing this solution:
[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, the shell-shaped dental instrument in this embodiment specifically includes: a shell-shaped body 10 that can be worn on the maxillary dentition, a dental arch portion 11 connected to the shell-shaped body 10 at the position of tooth No. 5, and a tongue guide structure 12 provided at the position of the palate midline L on the dental arch portion 11. The tongue guide structure 12 is a tongue protrusion that protrudes away from the palate, and the side away from the palate is a smooth arc surface, so as to reduce the stimulation during licking, avoid the thorns from damaging the tongue and other soft tissues of the oral cavity when contacting the tongue protrusion, reduce the foreign body sensation of the shell-shaped dental instrument when worn, and enhance the wearer's willingness to lick. The tongue protrusion in this embodiment is formed by extending part of the dental arch portion 11 away from the palate, specifically a partial sphere, such as a hemisphere, with a height of h, and the center just falls on the position of the palate midline L. Since it is provided on the palate midline L, the position of guiding the tongue to lick is relatively centered, which is conducive to the uniform force of the tongue.
[0042] After the shell-shaped dental device in this embodiment is worn on the patient's maxillary dentition, the patient can feel a slight foreign body sensation at the tongue protrusion, so that the tongue is induced to lick. At this time, it can be understood that the tongue licking the tongue protrusion is actually an involuntary tongue rolling movement, and the tongue rolling movement can help train the muscle strength and flexibility of the tongue. It can be understood that the height of the tongue protrusion will affect the stimulation of the patient after wearing it. When the height h is larger, the larger the space it occupies in the oral cavity, the stronger the foreign body sensation, and when the patient is guided to lick, the difficulty of the patient's tongue licking the tongue protrusion will be reduced, so the difficulty of tongue training can be changed by designing the height h.
[0043] In addition to the above-mentioned method of forming the tongue protrusion by extending the main body of the dental arch portion 11, some embodiments can also form the tongue protrusion by setting a protrusion at a relative position of the dental arch portion 11. The protrusion can specifically be a single-layer block solid formed by at least one of a sugar block, a calcium block, and a milk block, or a multiple-layer structure formed by multiple of them. The scheme for limiting the tongue protrusion can be combined with a slow-release structure with a sweet or milky taste, so as to induce the user to lick more through the taste, so as to enhance the training effect. Moreover, as the licking progresses, the volume of the above-mentioned protrusion becomes smaller and smaller as it dissolves, and through the design of the formula, the dissolution speed of the protrusion can be changed to control the length of time that the patient can be guided to lick after wearing it. At the same time, such a slow-release protrusion can also be used as an indicator of the length of time the patient wears it.
[0044] In addition, in some embodiments, the dental arch portion 11 is designed to provide expansion force for one or more teeth covered by the shell-shaped body 10. When the tongue guiding structure 12 guides the tongue to lick the top 111 of the dental arch portion 11, the dental arch portion 11 will be subjected to an upward pressure F1 when the tongue licks and squeezes the dental arch portion 11, thereby causing the dental arch portion 11 to deform, such as becoming a shape 11', and the top 111 of the dental arch portion 11 will move upward. At the same time, the tooth receiving cavity 10 will produce a tongue-directed (such as Figure 4 The tongue guide structure 12 may be licked by the tongue, and the tongue guide structure 12 may be licked by the tongue. The tongue guide structure 12 may be licked by the tongue, and the ... It can be understood that although the flexible connection portion 101 will absorb part of the force transmitted from the dental arch body, it can still be understood that the designed expansion force will meet the force applied by the deformation of the dental arch portion 11 and still have sufficient expansion force after deducting the absorbed force.
[0045] In addition to the above-mentioned method of designing the flexible connection portion 101, in some embodiments, the dental arch portion 11 can be designed to directly or indirectly contact the hard palate on the side close to the palate to absorb the reaction force exerted on the dental arch portion 11 when worn, and the reaction force comes from the force applied by the shell-like body 10 to one or more teeth of the patient. In some embodiments implemented by direct contact, the top 111 of the dental arch portion 11 can be designed to abut against the corresponding area of the hard palate. In some embodiments implemented by indirect contact, the top 111 of the dental arch portion 11 can be designed to abut against the corresponding area of the hard palate. Figure 5 As shown, the dental arch portion 11 includes a soft pad 14 disposed on the side of the dental arch portion 11 body close to the palate, so as to absorb at least part of the pressure when the dental arch portion 11 contacts the palate. By arranging the soft pad 14 between the dental arch portion 11 and the palate, when the dental arch portion 11 contacts the palate, at least part of the pressure is absorbed by the soft pad 14, thereby minimizing the foreign body sensation when worn. It can be understood that when the tongue 2 squeezes the dental arch portion 11, since the top of the dental arch portion 11 is against the hard palate area, and the tongue 2 has a certain width, the squeezing force F2 of the tongue 2 on the dental arch portion 11 will be dispersed to other areas of the top, and since the dental arch portion 11 has bending elasticity, the squeezing force F2 will be converted into a vertical expansion force in the T2 direction, and the dental arch portion 11 has an expansion tendency in the T2 direction, so as to assist in providing the expansion force. In addition, in some embodiments, the soft pad 14 is made of a water-absorbing and swellable material. By limiting the soft pad 14 to be made of a water-swelling material, when the soft pad 14 is soaked in saliva, the volume expands and a downward pressure is applied to the dental arch portion 11 to assist in arch expansion. Specifically, the water-swelling material can be PC, silicone rubber, etc., or other materials with relevant properties, which are not limited here. In addition, it can be understood that the shape of the soft pad can be as follows Fig.13 The square blocks shown may also be in other shapes, which are not listed here one by one.
[0046] In some embodiments, the shell body 10, the dental arch portion 11 and the tongue guide structure 12 can be integrally formed. The shell-shaped dental device in the present application is manufactured by integrally forming, which reduces the manufacturing cost and improves the integrity of the shell-shaped dental device.
[0047] It is worth mentioning that in addition to the above-mentioned setting of the tongue guiding structure 12 on the midline of the palate, in other embodiments, the tongue guiding structure 12 can also be set close to the midline of the palate. It does not need to be absolutely located at the midline of the palate. In another part of embodiments, the tongue guiding structure 12 can be set close to the shell-like body 10. The specific setting position is related to the target position where the tongue needs to be guided to lick. If the tongue needs to be guided to lick at a certain position, the tongue guiding structure 12 can be set at that position. The setting position is flexible and has little restriction. At the same time, the tongue guiding structures 12 at different positions can be combined to guide the tongue to lick multiple positions, so as to enhance the flexibility of tongue training, which will not be listed one by one here.
[0048] In some embodiments, a reinforcement part for enhancing the force applied by the dental arch part 11 is provided on the dental arch part 11, and the reinforcement part is one or more reinforcement ridges protruding from the dental arch part 11 and perpendicular to the surface of the dental arch part 11. When the tongue licks the tongue guide structure 12 to squeeze the dental arch part 11, its stress is dispersed to avoid damage caused by excessive compression and deformation of the dental arch part 11, and its anti-deformation ability is enhanced to avoid causing undesirable force on the teeth.
[0049] It is worth mentioning that although the present embodiment is described by taking the position where the dental arch portion 11 is connected to the shell-like body 10 corresponding to tooth No. 5 as an example, in actual applications, in other embodiments, the dental arch portion 11 can be connected to the position where the shell-like body 10 corresponds to other tooth positions, such as tooth No. 6, tooth No. 4, etc., or between teeth No. 5-6. Its setting position is flexible and will not be listed one by one here.
[0050] It can be understood that although the above-mentioned embodiment is described by taking a shell-shaped dental instrument including a dental arch portion 11 as an example, in actual applications, the shell-shaped tongue training instrument in some embodiments may include multiple dental arch portions 11, so as to further expand the area where the tongue guide structure 12 can be set through multiple dental arch portions 11, which will not be repeated here.
[0051] It can be seen that the shell-shaped dental instrument in this embodiment allows different functional devices to be used at the same time by setting a tongue guide structure 12 on the dental arch portion 11. When the user wears the shell-shaped dental instrument in this application, tongue training and tooth orthodontics can be carried out at the same time, which speeds up the correction efficiency. In addition, by presetting the shape, position, and number of the tongue guide structure 12, a variety of flexible training of the tongue can be achieved, so that doctors can design tongue training programs for patients more flexibly, increase the fun of the tongue training process, and increase the compliance of patients, which is especially conducive to promotion among pediatric patients. In addition, by designing the shape of the dental arch portion 11, it is achieved that the dental arch portion 11 can provide an expansion force, so that the shell-shaped dental instrument in this embodiment can simultaneously achieve expansion correction and tongue training when worn, combining the two correction methods to improve the overall correction efficiency.
[0052] Another embodiment of the present application also relates to a shell-shaped dental instrument. The difference between this embodiment and the previous embodiment is that in the previous embodiment, the tongue guiding structure 12 is a tongue protrusion protruding away from the palate, while in this embodiment, the tongue guiding structure 12 is a through hole portion, providing a variety of implementation methods, and can also be combined with other structures as needed to achieve a more flexible tongue guiding structure 12.
[0053] Specifically, the design of the through hole portion can also cause foreign body stimulation to the patient. In some embodiments, a through hole structure can be formed by cutting off a portion at a corresponding position of the dental arch portion 11. The bottom view of the structure is similar to Figure 2 The through-hole structure can reduce the coverage area of the dental arch portion 11 on the soft tissue in the oral cavity, enhance the air permeability after wearing, and enhance the comfort.
[0054] In some embodiments, the through hole portion is filled with: a single-layer solid block formed by at least one of sugar blocks, calcium blocks, and milk blocks, or a multi-layer structure formed by multiple of them. The through hole scheme can be combined with a slow-release structure with a sweet or milky taste to induce the user to lick more through the taste, so as to enhance the training effect.
[0055] It can be seen that in this embodiment, the tongue guiding structure 12 is realized by the through hole portion, which provides another form of tongue guiding structure 12, which can generate stimulation, guide the user to lick, and enrich the implementation method, so that different structural forms can be designed according to needs in actual applications to expand the application scenarios.
[0056] Another embodiment of the present application also relates to a shell-shaped dental instrument. This embodiment is substantially the same as the above embodiment, with the main difference being that in the above embodiment, a tongue guide structure 12 is provided on a shell-shaped dental instrument, while in the present embodiment, a plurality of tongue guide structures 12 are provided, so as to guide the tongue to lick a plurality of target positions, increase the range of tongue activity during tongue muscle training, and enhance the tongue training effect.
[0057] In some embodiments, there are multiple tongue guide structures 12, at least one of the multiple tongue guide structures 12 is located at or near the midline of the palate, and at least one is located near the shell body 10. In some embodiments where multiple tongue guide structures 12 are limited, some are located in the middle and some are located at the edge, and licking targets with different distances are combined to increase the difficulty of training, so as to enrich the tongue training program and adapt to different application scenarios. Figure 6 As shown, the invention specifically comprises three tongue guide structures 12, one of which is located at the palate midline L, and the other two tongue guide structures 12 are close to the shell-like body 10 and symmetrically distributed on both sides of the dental arch portion 11. Figure 7From the perspective of the figure, the three tongue guide structures 12 protrude away from the palate. In some embodiments, the sizes of the three tongue guide structures 12 may be different, such as the tongue guide structure 12 located on the palate midline L is larger, and the two tongue guide structures 12 close to the shell-like body 10 are smaller. It can be understood that the size can be characterized by at least one of the following: the area of the projection figure of the tongue guide structure 12 on the dental arch portion 11, the maximum width of the projection figure of the tongue guide structure 12 on the dental arch portion 11, the surface area of the tongue guide structure 12 facing the lingual side, and the height of the tongue guide structure 12 on the dental arch portion 11. It is defined that by setting tongue guide structures 12 with different parameters, tongue guide structures 12 of different sizes can be realized, the variation possibility of the tongue guide structure 12 is increased, and the morphological diversity of the tongue guide structure 12 is increased. In some embodiments, the shape of each tongue guide structure 12 can be set to a different shape, such as the hemispherical shape mentioned above, or a semi-ellipsoidal shape, or even a truncated cone, etc., which are not listed one by one here. For example, as determined by the figure of its projection on the dental arch portion 11, the projection figure can be referred to. Figure 6 In the bottom view, taking the tongue guide structure 12 as a hemispherical shape as an example, its projection figure is roughly circular. If the maximum width of the circle is used to represent the size, the width of the tongue guide structure 12 located on the midline of the palate is recorded as d1, and the maximum width of the projection figure of the two tongue guide structures 12 close to the shell-like body 10 on the dental arch 11 is recorded as d2, and d1 is designed to be greater than d2. The size of the tongue guide structure 12 is limited to avoid a tongue guide structure 12 that is too small, which makes licking too difficult and has no induction effect, and to avoid a tongue guide structure 12 that is too large and occupies too much space in the oral cavity, affecting the wearing experience. For another example, if the size is represented by the area of the projection figure, the projection area of the tongue guide structure 12 located on the midline of the palate on the dental arch 11 is designed to be larger than the projection area of the tongue guide structure 12 close to the shell-like body 10 on the dental arch 11. For another example, if the height of the tongue guide structure 12 is used to represent the size, the height h1 of the tongue guide structure 12 located on the midline of the palate is designed to be larger than the height h2 of the tongue guide structure 12 close to the shell-like body 10. Other embodiments may be characterized by using different parameters and combinations, which are not listed here one by one.
[0058] In other embodiments, the tongue guiding structure 12 may be disposed on the midline of the palate and near the shell-like body 10, such as Figure 8 As shown, seven tongue guide structures 12 can be provided, one of which is located at the midline L of the palate, and the remaining six are divided into two groups, with three in each group respectively distributed near the shell-like body 10, and the tongue guide structure 12 located at the midline L of the palate is larger in size.
[0059] In some embodiments, the maximum width of the projection pattern of the tongue guiding structure 12 on the dental arch portion 11 is 1-10 mm, such as Figure 6For example, d1 is 10mm, 8mm, 6mm, etc., and d2 is 1mm, 2mm, 3mm, etc., which are not listed here one by one. The size of the tongue guide structure 12 is limited to avoid a tongue guide structure 12 that is too small to make licking too difficult and has no induction effect, and to avoid a tongue guide structure 12 that is too large to occupy too much space in the oral cavity and affect the wearing experience.
[0060] In some embodiments, for the convenience of calculation, the above-mentioned projection on the dental arch 11 can use the surface where the dental arch 11 is located as the projection reference, specifically, the surface connected by the two sagittal anterior and posterior boundary lines of the dental arch 11 can be used as the reference, or the jaw plane can be used as the projection reference. When the projection reference is constant, the relative sizes of multiple tongue guide structures 12 can be determined, and the calculation is flexible and simple, and the design is convenient.
[0061] It can be seen that in this embodiment, multiple tongue guide structures 12 are set in the shell-shaped dental instrument, so as to guide the tongue to lick multiple target positions, increase the range of tongue movement during tongue muscle training, and enhance the tongue training effect. In some embodiments where multiple tongue guide structures 12 are limited, some are located in the middle and some are located at the edge, and licking targets with different distances are combined to increase the training difficulty, so as to enrich the tongue training program and adapt to different application scenarios. In addition, since different sizes of tongue guide structures 12 will cause different licking difficulties, tongue training of different difficulties can be combined by setting tongue guide structures 12 of different sizes to enrich the tongue training program.
[0062] Another embodiment of the present application also relates to a shell-shaped dental instrument. This embodiment is substantially the same as the above embodiment. A plurality of tongue guide structures 12 are also arranged in a shell-shaped dental instrument. The main difference is that: in the above embodiment, at least one tongue guide structure 12 is arranged at the midline of the palate and one tongue guide structure 12 is arranged at the midline of the palate. Fig. 9 As shown, the shape of a single tongue guide structure 12 is similar to any one of the tongue guide structures 12 in the aforementioned embodiments, and will not be repeated here.
[0063] In some embodiments, three tongue guide structures 12 are arranged at intervals along the midline of the palate, and the interval distance t1 between two adjacent tongue guide structures 12 is greater than 0 and less than or equal to 5 mm, such as 1 mm, 3 mm, etc. The tongue guide structures 12 arranged sagittally forward and backward are arranged at intervals of a certain distance to avoid excessive intervals that reduce the user's interest in licking.
[0064] It can be seen that in this embodiment, a plurality of tongue guide structures 12 are provided on a shell-shaped dental appliance at the same time, and the tongue guide structures 12 near the midline of the palate are arranged sagittally forward and backward. Since the more backward the position is in the sagittal direction, the more difficult it is to lick, and the tongue muscle strength required is stronger, the tongue guide structures 12 arranged sagittally forward and backward can guide the patient to gradually train the tongue muscles to improve the training effect. At the same time, the tongue guide structures 12 arranged sagittally forward and backward are arranged at intervals of a certain distance to avoid too large intervals, which reduces the user's interest in licking.
[0065] Another embodiment of the present application also relates to a shell-shaped dental instrument. In this embodiment, when the dental arch portion 11 is designed to provide auxiliary support force, the dental arch portion 11 is at least partially in contact with the palate on the side close to the palate.
[0066] Specifically, the contact may be direct or indirect. The shape of the dental arch portion 11 may be other shapes in addition to the strip shape in the aforementioned embodiment. Fig.10 As shown in the whole piece, the contour of the dental arch portion 11 is roughly the same as the contour of the hard palate area. After wearing, the dental arch portion 11 contacts the hard palate area so as to absorb the reaction force exerted on the dental arch portion 11 when worn, and the reaction force comes from the force applied by the shell-like body 10 to one or more teeth of the patient.
[0067] Some implementations such as Fig.11 As shown, a spacing hole structure 13 is provided between the dental arch portion 11 and the shell-like body 10, and the spacing hole structure 13 is provided between the anterior tooth area of the shell-like body 10 and the dental arch portion 11, or the spacing hole structure 13 is provided between the posterior tooth area of the shell-like body 10 and the dental arch portion 11. Further, the spacing hole structure 13 is provided between the left canine and the right canine in the anterior tooth area of the shell-like body 1011, and the length of the spacing hole structure 13 along the dental arch direction is the length of at least one tooth in the anterior tooth area in the mesiodistal direction. The spacing holes of the above structure can effectively isolate the dental arch portion 11 and the anterior tooth area of the shell-like body 10, effectively blocking the reaction force transmitted to the dental arch portion 11 from being transmitted to the anterior tooth area of the maxillary teeth, and avoiding the lip tilt of the teeth in the anterior tooth area.
[0068] Other parts of the implementation are as follows Fig.12 and Fig.13 As shown, the connection area between the dental arch portion 11 and the shell-like body 10 is wider, covering the area corresponding to teeth No. 4-6, thereby increasing the connection and binding of the area of teeth No. 4-6 to strengthen the mutual support of the teeth in the posterior area. At the same time, the dental arch portion 11 is widened at the top to form a supporting portion 102, which has a shape roughly the same as that of the hard palate area. After wearing, the supporting portion 102 can fit with the top of the hard palate area to increase the contact area at the top position, reduce the pressure on the surface mucosa of the hard palate area, and reduce the problem of mucosal damage in the hard palate area during the support. Specifically, Fig.12A tongue guiding structure 12 is provided in the Fig.13 Three tongue guiding structures 12 are arranged in a front-to-back manner. The number and position of the tongue guiding structures 12 can be designed according to the needs of tongue training, and will not be described in detail here.
[0069] It can be seen that in this embodiment, the dental arch portion 11 is designed to provide auxiliary support force so that when the patient wears the shell-shaped dental appliance, the molars can be pushed distally and the tongue can be trained at the same time, thereby achieving a composite implementation of the correction plan and shortening the overall correction period.
[0070] It can be understood that, in addition to being designed to provide the expansion force mentioned in the above embodiments, and to provide auxiliary support force for the distal movement of one or more posterior teeth, the dental arch portion 11 can also be designed to provide the contraction force in some embodiments. When designed to provide the contraction force, the tongue guide structure 12 provided on the dental arch portion 11 is similar to the tongue guide structure 12 in the aforementioned embodiments, which will not be repeated here.
[0071] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
