Description

TECHNICAL FIELD

[0001] The present application relates to the field of dental orthodontic appliances, and in particular, to a selective guide rail appliance. BACKGROUND

[0002] During the growth and development of children, malocclusion may occur due to congenital genetic factors and bad living habits, etc. This not only affects the appearance, but also may cause diseases such as dental caries, periodontal disease, and temporomandibular joint disease. Therefore, it is necessary to orthodontically treat the malocclusion of teeth.

[0003] The basic principle of orthodontics is to apply appropriate correction force to the teeth, so that the force is transmitted to the teeth, alveolar bone, periodontal tissue, jaw bone, and temporomandibular joint, thereby causing tissue remodeling, and ultimately achieving tooth movement.

[0004] At present, there are various types of medical devices for orthodontics, mainly including removable appliances, bracket appliances, and bite induction appliances. Among them, bite induction appliances are more and more used for children's orthodontics due to their convenience, comfort, and easy cleaning.

[0005] A general bite induction appliance includes a labial side wall, a lingual side wall, and a jaw pad connected between the two. The upper part of the labial side wall, the upper part of the lingual side wall, and the upper surface of the jaw pad form an upper accommodation groove for accommodating the upper dentition of the user, and the lower part of the labial side wall, the lower part of the lingual side wall, and the lower surface of the jaw pad form a lower accommodation groove for accommodating the lower dentition of the user. When worn, the upper and lower dentitions are respectively inserted into the upper and lower accommodation grooves, and the bite force is actively applied to the bite induction appliance, so that the reaction force of the appliance forms a correction force to orthodontically treat the teeth.

[0006] However, the general bite induction appliance is mass-produced in standardization, and the design of the upper and lower accommodation grooves does not take into account the situation that the user may have teeth that need to be avoided (i.e. teeth that need to be avoided from force, such as loose teeth, recently repaired teeth, etc.) or unerupted teeth. When used, the teeth that need to be avoided may be damaged by the correction force, or the unerupted teeth may not have enough space for eruption, affecting their normal growth.

[0007] The prior art needs to be improved in view of the above problems. Practical new type content

[0008] The purpose of the present application is to provide a selective guide rail appliance, which has the advantages of providing avoidance space for teeth that need to be avoided and providing eruption space for unerupted teeth.

[0009] The application provides a selective guide rail appliance, which is a bite induction appliance, comprising a labial side wall, a lingual side wall, and a jaw pad connected between the labial side wall and the lingual side wall, an upper part of the labial side wall, an upper part of the lingual side wall, and an upper surface of the jaw pad forming an upper accommodation groove for accommodating the upper dentition of a user, a lower part of the labial side wall, a lower part of the lingual side wall, and a lower surface of the jaw pad forming a lower accommodation groove for accommodating the lower dentition of the user; at least one partial position of the upper accommodation groove and / or the lower accommodation groove is provided with a guide rail groove; the guide rail groove is used to provide space for the user's teeth that need to be avoided to avoid contact with the selective guide rail appliance, or to provide space for the user's unerupted teeth to erupt.

[0010] The provision of the guide rail groove at least in one partial position of the upper accommodation groove and / or the lower accommodation groove provides space for the user's teeth that need to be avoided or for the unerupted teeth to erupt, thereby solving the problem that the existing bite induction appliance may cause damage to the teeth that need to be avoided or affect the normal growth of the unerupted teeth, and having the advantages of providing space for the teeth that need to be avoided and for the unerupted teeth to erupt.

[0011] Preferably, the selective guide rail appliance comprises at least one guide rail groove for providing space for the user's teeth that need to be avoided and / or at least one guide rail groove for providing space for the user's unerupted teeth to erupt.

[0012] This design allows the appliance to better adapt to the specific situation of the patient during the correction process. For teeth that need to be avoided, the guide rail groove provides space to avoid contact between the appliance and these teeth, thereby preventing unnecessary pressure or interference. For unerupted teeth, the guide rail groove provides space for future growth, allowing the appliance to continue to function during the eruption of the teeth.

[0013] Preferably, the positions of the upper accommodation groove and the lower accommodation groove other than the guide rail groove are provided with tooth grooves that are one-to-one corresponding and adapted to the teeth of the user other than the teeth that need to be avoided and the unerupted teeth.

[0014] This design achieves the dual function of providing space for the teeth that need to be avoided and the unerupted teeth, while accurately correcting other teeth. This design skillfully balances the needs of avoiding specific teeth and correcting other teeth, improves the accuracy and effectiveness of correction, increases the applicability of the appliance, can meet the individual needs of different patients, and may improve the comfort of wearing.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0048] It should be noted that: similar labels and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0049] ​​In the process of growth and development of children, due to congenital genetic factors or bad living habits, the phenomenon of misaligned teeth and the relationship between teeth and bones is more common. These malocclusion not only affects the appearance, but also can cause dental caries, periodontal disease and temporomandibular joint disease and other oral diseases. Therefore, it is of great significance to orthodontic teeth with malocclusion.

[0050] The basic principle of orthodontics is to apply appropriate correction force to make the alveolar bone, periodontal tissue, jaw and temporomandibular joint to be reconstructed and changed, and finally realize the movement and arrangement of teeth. The current widely used correction device mainly includes active correction device, bracket correction device and occlusal induction correction device. Among them, the occlusal induction correction device gradually becomes the preferred tool in the process of children's orthodontics because of its convenience, comfort and easy cleaning.

[0051] The general occlusal induction correction device is composed of a lip side wall, a tongue side wall and a jaw pad therebetween. When the patient places the upper and lower teeth into the upper and lower accommodation grooves respectively and applies the occlusal force, the reaction force of the correction device forms the correction force to apply continuous pressure on the teeth, thereby realizing the orthodontics of the teeth. However, the traditional occlusal induction correction device is produced according to the standardization batch, which inevitably has some limitations. These correction devices do not take into account the individual differences, such as some patients may have teeth that need to be avoided (i.e. teeth that need to be avoided from force, such as loose teeth, newly repaired teeth, etc.) or unerupted teeth. In this case, the standardized correction device applies unnecessary correction force to the teeth that need to be avoided, which may cause damage to the teeth. For unerupted teeth, the correction device cannot provide enough growth space, which may affect the normal eruption of the teeth.

[0052] To solve this problem, the present application proposes an innovative selective guide rail correction device design.

[0053] Please refer to Figures 1-12 The selective guide rail correction device in some embodiments of the present application is an occlusal induction correction device, which includes a lip side wall 1, a tongue side wall 2 and a jaw pad 3 connected between the lip side wall 1 and the tongue side wall 2. The upper part of the lip side wall 1, the upper part of the tongue side wall 2 and the upper surface of the jaw pad 3 form an upper accommodation groove for accommodating the upper teeth of the user. The lower part of the lip side wall 1, the lower part of the tongue side wall 2 and the lower surface of the jaw pad 3 form a lower accommodation groove for accommodating the lower teeth of the user. At least one local position of the upper accommodation groove and / or the lower accommodation groove is provided with a guide rail groove 4. The guide rail groove 4 is used to provide a space for the teeth that need to be avoided by the user to avoid the contact between the teeth that need to be avoided and the selective guide rail correction device, or to provide an eruption space for the unerupted teeth of the user.

[0054] At least one partial position of the upper accommodation groove and / or the lower accommodation groove is provided with a guide groove 4 for providing space for the avoidance of the user's teeth that need to be avoided or for the eruption of the unerupted teeth, thereby solving the problem that the existing bite induction appliance may cause damage to the teeth that need to be avoided or affect the normal growth of the unerupted teeth, and having the advantages of being able to provide space for the avoidance of the teeth that need to be avoided and for the eruption of the unerupted teeth.

[0055] The design of the guide groove 4 is flexible and diverse, and can be customized according to the specific needs of the patient. For teeth that need to be avoided, the guide groove 4 can be designed as a cavity with a size larger than the teeth that need to be avoided (for example Figure 1 For unerupted teeth, the guide groove 4 can be designed as a groove that is adapted to the expected shape and size of the unerupted teeth after eruption (the expected shape and size can be predicted by existing technology).

[0056] The position of the guide groove 4 can also be flexibly set as needed. They can be set at any position of the upper accommodation groove or the lower accommodation groove, and can be single or multiple, symmetrically distributed left and right, or asymmetrically distributed according to the special circumstances of the patient.

[0057] Since the user may have teeth that need to be avoided but no unerupted teeth, have unerupted teeth but no teeth that need to be avoided, or have both teeth that need to be avoided and unerupted teeth, the corresponding selected guide appliance includes at least one guide groove 4 for providing space for the user's teeth that need to be avoided and / or at least one guide groove 4 for providing space for the user's unerupted teeth.

[0058] This design allows the appliance to better adapt to the specific circumstances of the patient during the correction process. For teeth that need to be avoided, the guide groove 4 provides space to avoid contact between the appliance and these teeth, thereby preventing unnecessary pressure or interference. For unerupted teeth, the guide groove 4 provides space for future growth, allowing the appliance to continue to function during the eruption of the teeth.

[0059] The position and number of guide grooves 4 can also be adjusted as needed. For example, multiple guide grooves 4 can be provided at different positions of the upper accommodation groove and the lower accommodation groove to accommodate multiple teeth that need to be avoided or unerupted. These guide grooves 4 can be symmetrically distributed left and right, or asymmetrically distributed, depending on the actual situation of the patient's teeth.

[0060] Preferably, positions other than the guide groove 4 in the upper accommodation groove and the lower accommodation groove are provided with tooth grooves 5 that are one-to-one adapted to the user's teeth other than the teeth that need to be avoided and the unerupted teeth (the shape, size and position are all adapted so that the tooth groove 5 can closely fit the corresponding teeth to ensure that precise correction force is provided to the corresponding teeth).

[0061] This design achieves the dual function of providing space for teeth to be avoided and unerupted teeth, while accurately treating other teeth. This design skillfully balances the needs of avoiding specific teeth and treating other teeth, improving the accuracy and effectiveness of treatment, increasing the applicability of the appliance, and meeting the individual needs of different patients, and may improve the comfort of wearing.

[0062] Specifically, the design of the tooth groove 5 can be customized according to the patient's dental condition. The shape, size and position of the tooth groove 5 can be accurately matched to the patient's dental morphology. For example, for the anterior teeth area, the tooth groove 5 can be designed to be slightly inclined in shape to guide the teeth to move to the ideal position (as shown in Figure 3 For the molar area, the tooth groove 5 can be designed to be wider in shape to provide sufficient support and stability (as shown in Figure 3

[0063] The inner surface of the tooth groove 5 can be designed as a smooth curve, which can reduce friction and improve the comfort of wearing. At the same time, small protrusions or grooves can be added inside the tooth groove 5, which can provide additional treatment force to guide the teeth to move in a specific direction.

[0064] In some embodiments, the upper accommodation groove and / or the lower accommodation groove are provided with guide rail grooves 4 symmetrically left and right.

[0065] The left and right symmetrical arrangement of the guide rail groove 4 has the advantages of balance, applicability, aesthetics and universality. By arranging the guide rail groove 4 symmetrically left and right, the selected area guide rail appliance can better meet the individual needs of patients, while ensuring the treatment effect and wearing comfort. When the patient wears the appliance, the teeth to be avoided or the unerupted teeth will naturally enter the corresponding guide rail groove 4. Since the guide rail groove 4 is arranged symmetrically left and right, the force of the appliance in the oral cavity is more balanced, reducing the discomfort caused by excessive unilateral force. At the same time, for the case of needing to avoid teeth or reserve space for unerupted teeth on both sides, this design can meet the needs of both sides at the same time, improving the applicability and universality of the appliance. In addition, the left and right symmetrical design is more coordinated in appearance, improving the aesthetics of the appliance, which has a positive effect on increasing the patient's willingness to wear and compliance. Compared with traditional standardized mass-produced occlusal induction appliances, the design of the present application is more flexible, can better meet the individual needs of patients, while ensuring the treatment effect and wearing comfort.

[0066] The left and right symmetrical arrangement of the guide rail groove 4 can have various implementations.

[0067] ​For example, the upper accommodation groove and / or the lower accommodation groove is provided with one left-right symmetrical guide rail groove 4. Generally, when there are teeth to be avoided or unerupted teeth in the anterior tooth area of the user, a left-right symmetrical guide rail groove 4 is arranged in the anterior tooth area, but the range of the left-right symmetrical guide rail groove 4 is not limited to only the anterior tooth area. For example: the 1-1 tooth area (such as Figures 4-6 In the 1-1 tooth area of the upper accommodation groove and the lower accommodation groove, a left-right symmetrical guide rail groove 4 is arranged; Figures 7-9 In the 2-2 tooth area of the upper accommodation groove and the lower accommodation groove, a left-right symmetrical guide rail groove 4 is arranged; Figures 13-15 In the 2-2 tooth area of the upper accommodation groove, a left-right symmetrical guide rail groove 4 is arranged; the 3-3 tooth area, the 4-4 tooth area, the 5-5 tooth area, the 6-6 tooth area, the 7-7 tooth area or the 8-8 tooth area is provided with a left-right symmetrical guide rail groove 4; wherein, referring to the tooth position diagram shown in Figure 31 For the upper dentition, the 1-1 tooth area refers to the area from tooth No. 11 to tooth No. 21, the 2-2 tooth area refers to the area from tooth No. 12 to tooth No. 22, and so on; for the lower dentition, the 1-1 tooth area refers to the area from tooth No. 31 to tooth No. 41, the 2-2 tooth area refers to the area from tooth No. 32 to tooth No. 42, and so on.

[0068] For example, the upper accommodation groove and / or the lower accommodation groove is provided with two groups of left-right symmetrical guide rail grooves 4, each group of guide rail grooves 4 includes at least one guide rail groove 4 (one or more than one). Generally, when there are teeth to be avoided or unerupted teeth in the posterior tooth area of the user, corresponding guide rail grooves 4 are arranged in the corresponding posterior tooth area, but the range of the left-right symmetrical guide rail groove 4 is not limited to only the posterior tooth area. Taking the case of one guide rail groove 4 in each group as an example, such as: in the upper accommodation groove, the 11-12 tooth area and the 21-22 tooth area, the 11-13 tooth area and the 21-23 tooth area, …, the 11-18 tooth area and the 21-28 tooth area, the 12-13 tooth area and the 22-23 tooth area, the 12-14 tooth area and the 22-24 tooth area, …, the 12-18 tooth area and the 22-28 tooth area, the 13-14 tooth area and the 23-24 tooth area (such as Figures 1-3 In the 13-14 tooth area and the 23-24 tooth area of the upper accommodation groove, a guide rail groove 4 is arranged; the 13-15 tooth area and the 23-25 tooth area, …, the 13-18 tooth area and the 23-28 tooth area, the 14-15 tooth area and the 24-25 tooth area, the 14-16 tooth area and the 24-26 tooth area, …, the 14-18 tooth area and the 24-28 tooth area, the 15-16 tooth area and the 25-26 tooth area (such as Figures 10-12In the upper accommodating groove, the 15-16 tooth area and the 25-26 tooth area are provided with a guide rail groove 4, the 15-17 tooth area and the 25-27 tooth area, the 15-18 tooth area and the 25-28 tooth area, the 16-17 tooth area and the 26-27 tooth area, the 16-18 tooth area and the 26-28 tooth area, or the 17-18 tooth area and the 27-28 tooth area are provided with a guide rail groove 4.

[0069] In the lower accommodating groove, the 31-32 tooth area and the 41-42 tooth area, the 31-33 tooth area and the 41-43 tooth area, the 31-38 tooth area and the 41-48 tooth area, the 32-33 tooth area and the 42-43 tooth area, the 32-34 tooth area and the 42-44 tooth area, the 32-38 tooth area and the 42-48 tooth area, the 33-34 tooth area and the 43-44 tooth area (for example Figures 1-3 In the lower accommodating groove, the 33-34 tooth area and the 43-44 tooth area are provided with a guide rail groove 4, the 33-35 tooth area and the 43-45 tooth area, the 33-38 tooth area and the 43-48 tooth area, the 34-35 tooth area and the 44-45 tooth area, the 34-36 tooth area and the 44-46 tooth area, the 34-38 tooth area and the 44-48 tooth area, the 35-36 tooth area and the 45-46 tooth area (for example Figures 10-12 In the lower accommodating groove, the 35-36 tooth area and the 45-46 tooth area are provided with a guide rail groove 4, the 35-37 tooth area and the 45-47 tooth area, the 35-38 tooth area and the 45-48 tooth area, the 36-37 tooth area and the 46-47 tooth area, the 36-38 tooth area and the 46-48 tooth area, or the 37-38 tooth area and the 47-48 tooth area are provided with a guide rail groove 4.

[0070] In the lower accommodating groove, the 33-34 tooth area and the 43-44 tooth area are provided with a guide rail groove 4, the 33-35 tooth area and the 43-45 tooth area, the 33-38 tooth area and the 43-48 tooth area, the 34-35 tooth area and the 44-45 tooth area, the 34-36 tooth area and the 44-46 tooth area, the 34-38 tooth area and the 44-48 tooth area, the 35-36 tooth area and the 45-46 tooth area (for example Figure 31 As shown in the tooth position diagram, for the upper teeth, the 11-12 tooth area refers to the area from tooth No. 11 to tooth No. 12, the 21-22 tooth area refers to the area from tooth No. 21 to tooth No. 22, the 11-13 tooth area refers to the area from tooth No. 11 to tooth No. 13, the 21-23 tooth area refers to the area from tooth No. 21 to tooth No. 23, and so on; for the lower teeth, the 31-32 tooth area refers to the area from tooth No. 31 to tooth No. 32, the 41-42 tooth area refers to the area from tooth No. 41 to tooth No. 42, the 31-33 tooth area refers to the area from tooth No. 31 to tooth No. 33, the 41-43 tooth area refers to the area from tooth No. 41 to tooth No. 43, and so on.

[0071] It should be noted that the above two examples of left-right symmetry can exist alone or simultaneously, for example Figures 16-18 In the upper accommodating groove, the 2-2 tooth area is provided with a left-right symmetrical guide rail groove 4, and the 33-36 tooth area and the 43-46 tooth area of the lower accommodating groove are provided with a guide rail groove 4.

[0072] In other embodiments, the upper accommodation groove and / or the lower accommodation groove are asymmetrically provided with the guide groove 4.

[0073] This asymmetric arrangement can provide more precise space for the teeth that need to be avoided or for the unerupted teeth according to the actual situation of the user's teeth. The technical feature of asymmetrically arranging the guide groove 4 allows the selected area guide appliance to better adapt to the individual needs of different users. This design allows the appliance to have different numbers, sizes, or positions of guide grooves 4 on the left and right sides, respectively, so as to be more precisely customized for each user's specific tooth situation. In addition, since it can more accurately provide space for teeth that need to be avoided, unnecessary interference is avoided while not affecting the normal correction of other teeth, thus possibly speeding up the overall correction process. This not only improves the correction efficiency, but also possibly reduces the user's discomfort and improves the overall user experience.

[0074] The asymmetrically arranged guide groove 4 can have various implementations.

[0075] For example, the upper accommodation groove and / or the lower accommodation groove are provided with at least one guide groove 4 only on the left side or the right side. If the user's upper dentition has teeth that need to be avoided or unerupted teeth only on one side of the left and right sides, the upper accommodation groove can only have a guide groove 4 on the corresponding side; if the user's lower dentition has teeth that need to be avoided or unerupted teeth only on one side of the left and right sides, the lower accommodation groove can only have a guide groove 4 on the corresponding side.

[0076] Thus, one of the following situations can occur:

[0077] 1. The upper accommodation groove is provided with at least one guide groove 4 only on the left side;

[0078] 2. The upper accommodation groove is provided with at least one guide groove 4 only on the right side;

[0079] 3. The lower accommodation groove is provided with at least one guide groove 4 only on the left side;

[0080] 4. The lower accommodation groove is provided with at least one guide groove 4 only on the right side;

[0081] 5. The upper accommodation groove is provided with at least one guide groove 4 on the left side and the lower accommodation groove is provided with at least one guide groove 4 on the left side; for example Figures 28-30 In the 22-23 tooth area of the upper accommodation groove and the 32-33 tooth area of the lower accommodation groove are provided with one guide groove 4; Figures 25-27 In the 22-24 tooth area of the upper accommodation groove and the 32-34 tooth area of the lower accommodation groove are provided with one guide groove 4; Figures 22-24 In the 22-25 tooth area of the upper accommodation groove and the 32-35 tooth area of the lower accommodation groove are provided with one guide groove 4; Figures 19-21The 22-27 tooth area of the upper accommodation groove is provided with a guide groove 4, and the 32-37 tooth area of the lower accommodation groove is provided with a guide groove 4;

[0082] 6. The right side of the upper accommodation groove is provided with at least one guide groove 4, and the right side of the lower accommodation groove is provided with at least one guide groove 4;

[0083] 7. The left side of the upper accommodation groove is provided with at least one guide groove 4, and the right side of the lower accommodation groove is provided with at least one guide groove 4;

[0084] 8. The right side of the upper accommodation groove is provided with at least one guide groove 4, and the left side of the lower accommodation groove is provided with at least one guide groove 4.

[0085] Wherein, the extension range of each guide groove 4 can refer to the foregoing.

[0086] Or for example, the left and right sides of the upper accommodation groove and / or the lower accommodation groove are each provided with at least one guide groove 4, and the distribution positions of the guide grooves 4 on the left and right sides are asymmetric. If the user has teeth to be avoided or unerupted teeth on the left and right sides of the upper dentition, and the teeth to be avoided or unerupted teeth on the left and right sides are asymmetric, then the upper accommodation groove can be provided with asymmetric guide grooves 4 on the left and right sides; if the user has teeth to be avoided or unerupted teeth on the left and right sides of the lower dentition, and the teeth to be avoided or unerupted teeth on the left and right sides are asymmetric, then the lower accommodation groove can be provided with asymmetric guide grooves 4 on the left and right sides. Thus, one of the following situations can occur:

[0087] 1. Only the left and right sides of the upper accommodation groove are provided with at least one guide groove 4, and the distribution positions of the guide grooves 4 on the left and right sides are asymmetric;

[0088] 2. Only the left and right sides of the lower accommodation groove are provided with at least one guide groove 4, and the distribution positions of the guide grooves 4 on the left and right sides are asymmetric;

[0089] 3. The left and right sides of the upper accommodation groove are each provided with at least one guide groove 4, and the left and right sides of the lower accommodation groove are each provided with at least one guide groove 4, the distribution positions of the guide grooves 4 on the left and right sides of the upper accommodation groove are asymmetric, and the distribution positions of the guide grooves 4 on the left and right sides of the lower accommodation groove are asymmetric.

[0090] It should be noted that the above two examples of non-symmetrical arrangement can exist alone or simultaneously. For example, while the upper accommodating groove is provided with at least one guide rail groove 4 only on the left side or the right side, the left side and the right side of the lower accommodating groove are both provided with at least one guide rail groove 4, and the distribution positions of the guide rail grooves 4 on the left and right sides are asymmetric; or, while the lower accommodating groove is provided with at least one guide rail groove 4 only on the left side or the right side, the left side and the right side of the upper accommodating groove are both provided with at least one guide rail groove 4, and the distribution positions of the guide rail grooves 4 on the left and right sides are asymmetric.

[0091] In the present application, the selected area guide rail appliance is an integral product, which is more conducive to ensuring that the structural integrity and mechanical properties of the product meet the requirements, for example, it can be prepared by using a 3D printing process, but is not limited thereto.

[0092] In the present application, the selected area guide rail appliance can be prepared from at least one of medical materials such as silicone, thermoplastic elastomer, TPU, TPE, polyurethane, nylon, PETG, etc., and preferably silicone, which is more comfortable to wear.

[0093] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
