Description

Technical Field

[0001] This utility model relates to the field of medical devices, more specifically to the field of oral appliances, and particularly to a shell-shaped dental instrument and orthodontic system for snoring prevention. Background Technology

[0002] Snoring is a common sleep phenomenon. To date, most people still consider snoring commonplace and take it for granted. Some even see snoring as a sign of sound sleep. In fact, snoring is a major health hazard. Snoring can lead to adverse consequences such as daytime sleepiness, fatigue, poor concentration, headaches, and decreased work performance. Severe snoring is often accompanied by sleep apnea syndrome, which seriously affects the patient's health.

[0003] There are many causes of snoring, with the most common being airway obstruction. The nasal cavity and oral cavity are both connected to the airway. When a person is asleep, airway obstruction can occur due to muscle relaxation, jaw retraction, and tongue falling back. People in this situation often breathe through their mouths to allow air to pass. One way to open the airway is to pull the jaw forward, increasing the muscle tension in the throat, tongue, and soft palate, thus opening the airway that has collapsed due to muscle relaxation during sleep. Therefore, for snoring caused by this reason, the method to stop snoring is to pull the jaw forward to the ideal position to open the airway.

[0004] In recent years, invisible dental instruments have become increasingly popular in the field of orthodontics due to their aesthetic appeal and convenience. Orthodontic manufacturers have also attempted to combine anti-snoring devices with invisible dental instruments. Currently, invisible dental instruments used to treat snoring often use a connecting rod to guide and hold the mandible forward to a position that opens the airway. However, this type of device requires the mandible to be pulled forward beyond the mounting point of the maxilla to complete the connection, causing severe discomfort for patients. Furthermore, it affects the patient's mouth opening, leading to nighttime awakenings due to suffocation. This results in low user acceptance and hinders market promotion. Although there have been improvements in the technical solutions for anti-snoring devices, such as the dental instrument for anti-snoring provided in Chinese patent CN202420429948.8, which has an elastic part on the connector so that when the connector is hooked to the protrusion of the maxilla, the elastic part undergoes elastic deformation due to the force along the long axis of the connector, so that the connector has a certain buffering effect when hooking the protrusion. This effectively solves the discomfort caused by the patient's mandible being pulled too far forward in the sagittal direction during installation. However, the problem of the patient's mouth opening being affected after wearing the device has not yet been solved, and the comfort needs to be improved.

[0005] Therefore, it is necessary to provide an anti-snoring device that is simple in structure, can effectively suppress snoring, and can solve the discomfort problems during and after wearing. Utility Model Content

[0006] The technical problem solved by this utility model is to overcome the defects of the existing technology and provide a stable, reliable and comfortable shell-shaped dental instrument and orthodontic system for snoring prevention.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A shell-shaped dental instrument for snoring prevention includes: A first shell-like body that accommodates the patient's maxillary teeth and a second shell-like body that accommodates the patient's mandibular teeth; The first shell-shaped body has a first repositioning jaw element extending towards the opposing jaw on each side of the posterior tooth region. The first repositioning jaw element includes a first base connected to the first shell-shaped body. The first base extends towards the opposing jaw and is provided with a first locking part. The first locking part includes a first protrusion disposed at the free end of the first locking part and a first connecting part connecting the first protrusion and the first base. The first protrusion, the first connecting part and the first base enclose a first locking cavity with an opening facing the mesial direction. The second shell-shaped body has second repositioning occlusal elements extending towards the opposing jaw on both sides of the posterior tooth region. Each second repositioning occlusal element includes a second base connected to the second shell-shaped body. The second base extends towards the opposing jaw and has a second locking portion. The second locking portion includes a second protrusion at its free end and a second connecting portion connecting the second protrusion and the second base. The second protrusion, the second connecting portion, and the second base together form a second locking cavity with an opening facing distally. The outer contour dimension of the first protrusion is smaller than the inner contour dimension of the second locking cavity, and the outer contour dimension of the second protrusion is smaller than the inner contour dimension of the first locking cavity. The first connecting part is provided with a first guide surface on the side facing the near center, and the second connecting part is provided with a second guide surface on the side facing the far center; When worn, the first and second repositioning jaw elements cooperate to move the patient's mandible forward in the sagittal direction to a preset position that opens the patient's airway, thereby suppressing snoring: the first protrusion is housed in the second locking cavity, and the surface of the first protrusion facing the mesial side at least partially abuts against the second guide surface; the second protrusion is housed in the first locking cavity, and the surface of the second protrusion facing the distal side at least partially abuts against the first guide surface; the projection of the first guide surface on the horizontal plane has a first preset length in the sagittal direction, and the projection of the first guide surface on the coronal plane has a first preset height in the gingival-maxillary direction; when the second protrusion slides along the first guide surface, it causes the second guide surface to slide relative to the first protrusion, wherein the second protrusion can slide within a second preset length in the sagittal direction, and simultaneously, it can slide within a second preset height in the gingival-maxillary direction, the second preset length being less than the first preset length, and the second preset height being less than the first preset height.

[0008] This design, on the one hand, through the locking engagement of the first and second repositioning jaw elements, ensures that after wearing, the first protrusion is housed within the second locking cavity, with at least a portion of the surface of the first protrusion facing the mesial side abutting against the second guide surface, and the second protrusion is housed within the first locking cavity, with at least a portion of the surface of the second protrusion facing the distal side abutting against the first guide surface. This provides stable and reliable support for the forward movement of the mandible, opening the patient's airway and ensuring the effectiveness of snoring suppression. On the other hand, by setting a first preset length in the sagittal direction and a first preset height in the gingival-maxillary direction for the first and second guide surfaces, the patient's mandible can slide within a certain range in both the sagittal and gingival-maxillary directions, providing the patient with dynamic adaptation space. This ensures patient comfort while precisely controlling the forward movement of the mandible.

[0009] Preferably, the first preset height satisfies the following condition: when the second protrusion slides along the first guide surface upwards to one end of the first guide surface near the first protrusion, the gap between the incisal edges of the maxillary and mandibular anterior teeth in the upwards gingival direction is within a preset gap range. This setting effectively prevents excessive open bite or discomfort caused by temporomandibular joint dislocation. Furthermore, the preset gap ensures airflow to the anterior teeth region, maintaining airway patency and facilitating treatment effectiveness.

[0010] Preferably, the lower surface of the first protrusion facing the opposing jaw and the upper surface of the second base facing the opposing jaw are a set of surfaces with matched contours, and the lower surface of the first protrusion facing the opposing jaw and the upper surface of the second base facing the opposing jaw make surface contact when they come into contact, and / or, the upper surface of the second protrusion facing the opposing jaw and the lower surface of the first base facing the opposing jaw are a set of surfaces with matched contours, and the upper surface of the second protrusion facing the opposing jaw and the lower surface of the first base facing the opposing jaw make surface contact when they come into contact. This surface contact design improves the stability of the fit between the first and second repositioning jaw elements, reduces local wear at the contact points, and facilitates the achievement of orthodontic effects; moreover, surface contact reduces the discomfort that may be caused by point or line contact.

[0011] Preferably, the first base and the second base each cover at least two-thirds of the lateral width of one tooth in their corresponding posterior tooth region in the mesiodistal direction. This arrangement ensures sufficient support area between the first base and the first shell-like body, as well as between the second base and the second shell-like body, thereby guaranteeing the installation reliability of the first and second repositioning jaw elements.

[0012] Preferably, the distal ends of both the first and second repositioning jaw elements do not exceed the mesial end of the penultimate tooth position in the patient's posterior tooth region.

[0013] Preferably, a first occlusal pad protruding towards the opposing jaw is provided on the occlusal surface of at least one tooth in the posterior tooth region on both sides of the first shell-shaped body; the protrusion height of the first occlusal pad is used to open the anterior tooth region of the patient's upper and lower jaws to a first target height. Alternatively, at least one tooth in the occlusal surface of the posterior region on both sides of the second shell-like body is provided with a second occlusal pad protruding towards the opposing jaw; the protrusion height of the second occlusal pad is used to open the anterior region of the patient's upper and lower jaws to a second target height. The design of the first or second occlusal pad further assists in airway opening and improves the treatment effect. At the same time, the protrusion height of the first or second occlusal pad can be adjusted according to the patient's specific situation to achieve personalized treatment.

[0014] Preferably, a third occlusal pad protruding towards the opposing jaw is provided on the occlusal surfaces of the two posterior tooth regions of the first shell-shaped body, and a fourth occlusal pad protruding towards the opposing jaw is provided on the occlusal surfaces of the two posterior tooth regions of the second shell-shaped body corresponding to the position of the third occlusal pad. When worn, the top surfaces of the third occlusal pad and the fourth occlusal pad facing the opposing jaw bite each other. The total height of the protrusions of the third occlusal pad and the fourth occlusal pad is used to open the anterior tooth region of the patient's upper and lower jaws to the third target height.

[0015] Preferably, when the first shell-shaped body is provided with a first jaw pad, the side of the first repositioning jaw element near the tooth and the side of the first jaw pad near the first repositioning jaw element are disposed adjacent to each other. When the second shell-shaped body is provided with the second jaw pad, the side of the second repositioning jaw element near the tooth and the side of the second jaw pad near the second repositioning jaw element are adjacent to each other. The adjacent design transmits the force guiding the mandible forward from the first locking part to the first jaw pad or from the second locking part to the second jaw pad, reducing deformation of the shell-shaped dental instrument.

[0016] Preferably, when the first shell-shaped body is provided with a first jaw pad, a first transition portion is further provided between the side of the first repositioning jaw element near the tooth and the side of the first jaw pad near the first repositioning jaw element, and the first transition portion is supported on the occlusal surface of the tooth covered by the first repositioning jaw element. When the second shell-shaped body is provided with the second occlusal pad, a second transition portion is further provided between the side of the second repositioning occlusal element near the tooth and the side of the second occlusal pad near the second repositioning occlusal element. The second transition portion supports the occlusal surface of the tooth covered by the second repositioning occlusal element. The design of the first transition portion allows the gingival-occlusal force on the first repositioning occlusal element and the first occlusal pad to be supported by the tooth covered by the first transition portion, or the design of the second transition portion allows the gingival-occlusal force on the second repositioning occlusal element and the second occlusal pad to be supported by the tooth covered by the second transition portion, thereby improving the overall integrity and mechanical strength of the shell-shaped dental instrument.

[0017] Preferably, the first transition portion and the second transition portion are further provided with reinforcing ridges to enhance their mechanical strength. These reinforcing ridges are formed by the first and second transition portions, which are concave or convex towards the distal or mesial tooth side, and extend along the mesiodistal or buccal-lingual direction. The reinforcing ridges further enhance the mechanical strength of the first and second transition portions, thereby extending the service life of the shell-shaped dental instrument.

[0018] Preferably, the side surfaces of the first and second repositioning jaw elements are further provided with reinforcing ridges to enhance their mechanical strength. These reinforcing ridges are formed by the concave or convex side surfaces of the first and second repositioning jaw elements, extending along the gingival-maxillary direction, and are a plurality of grooved or protruding structures. The surfaces of the first and second jaw pads are further provided with reinforcing ridges to enhance their mechanical strength. These reinforcing ridges are formed by concave or convex surfaces of the first and second jaw pads, extending along the gingival direction. The reinforcing ridges further enhance the mechanical strength of the first and second repositioning jaw elements, as well as the first or second jaw pad, thereby extending the service life of the shell-shaped dental instrument.

[0019] To achieve the objective of this invention, this application also provides a dental orthodontic system, comprising multiple sets of shell-shaped dental instruments. These multiple sets of shell-shaped dental instruments include at least two sets of shell-shaped dental instruments as described above. The first or second occlusal pad in each of the at least two sets of shell-shaped dental instruments has a different height of upward convexity towards the opposing jaw along the gingival direction. During the orthodontic process, the height at which the later set of shell-shaped dental instruments opens the patient's upper and lower anterior teeth is less than the height at which the earlier set of shell-shaped dental instruments opens the patient's upper and lower anterior teeth. By gradually adjusting the height of the first or second occlusal pad, a gradual reduction in the height of the patient's upper and lower anterior teeth is achieved, providing the patient with a gradual adaptation process, gradually correcting mouth breathing habits, making it more acceptable to the patient, and improving patient comfort.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of the invention. However, the technical solutions claimed by this utility model can be implemented even without these technical details and with various variations and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this utility model.

[0023] The directional terms "up," "down," "left," and "right" used in this document refer to the directions shown in the accompanying drawings and do not imply any specific limitation. Unless otherwise explicitly stated or limited, the term "connection" in this document should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part of a structure. It can refer to a direct connection or an indirect connection through an intermediate medium.

[0024] In the various embodiments of this invention, the term "posterior tooth region" is defined according to the classification of teeth in the 2nd edition of *Introduction to Stomatology*, published by Peking University Medical Press, pages 36-38. It includes premolars and molars, teeth marked as 4-8 using the FDI notation, and teeth marked as 1-3 using the FDI notation for the anterior tooth region. The teeth in the anterior tooth region include the central incisors, lateral incisors, and canines.

[0025] The following will provide a detailed explanation in conjunction with the illustrations. Example

[0026] Please refer to Figures 1 to 4 As shown, the shell-shaped dental instrument 100 provided in this application includes a first shell-shaped body 1 for accommodating the patient's maxillary teeth and a second shell-shaped body 2 for accommodating the patient's mandibular teeth. The first shell-shaped body 1 has first repositioning occlusal elements 3 extending towards the opposing jaw on both sides of the posterior tooth region. The first repositioning occlusal element 3 includes a first base 31 connected to the first shell-shaped body 1. The first base 31 has a first locking portion 32 extending towards the opposing jaw. The first locking portion 32 includes a first protrusion 33 disposed at the free end of the first locking portion 32 and a first connecting portion 34 connecting the first protrusion 33 and the first base 31. The first protrusion 33, the first connecting portion 34, and the first base 31 together form a first locking cavity 5 with an opening facing the mesial direction. The first connecting portion 34 has a first guide surface 341 on its proximal side. The projection of the first guide surface 341 onto the horizontal plane has a first preset length L in the sagittal direction. This arrangement allows the patient's mandible to slide within a certain range in the sagittal direction, specifically within a second preset length L1. For example, the sagittal direction can be... Figure 4 Sliding within the range of 0-L1, as shown, can relieve joint stiffness and improve comfort, where L1 is less than L; and, the projection of the first guide surface 341 on the coronal plane has a first preset height H in the gingival-maxillary direction. This setting allows the patient's mandible to have a certain amount of micro-movement space in the gingival-maxillary direction, specifically, sliding within the range of a second preset height H1. For example, in the gingival-maxillary direction, it can... Figure 4The device moves within the range of 0-H1, accommodating involuntary nighttime activities such as mouth opening or nighttime teeth grinding, providing a comfortable wearing experience for patients. Here, H1 is less than H. In some embodiments, the first guide surface 341 can be arc-shaped. In other embodiments, provided that the projection of the first guide surface on the horizontal plane has the first preset length L in the sagittal direction, and the projection of the first guide surface 341 on the coronal plane has the first preset height H in the gingival-maxillary direction, the first guide surface 341 can also be an inclined plane.

[0027] The second shell-shaped body 2 has a second repositioning jaw element 4 extending towards the opposing jaw on each of its two posterior tooth regions. The placement of the second repositioning jaw element 4 on the second shell-shaped body 2 corresponds to the placement of the first repositioning jaw element 3. Specifically, the placement of the second repositioning jaw element 4 needs to satisfy the following condition: when worn, the second repositioning jaw element 4 and the first repositioning jaw element 3 can contact and engage at a preset position. The preset position is one that can guide the patient's mandible forward in the sagittal direction to a position that can open the airway and thus suppress snoring.

[0028] Continuing the explanation, the second repositioning jaw element 4 includes a second base 41 connected to the second shell-shaped body 2. The second base 41 extends towards the opposing jaw and is provided with a second locking portion 42. The second locking portion 42 includes a second protrusion 43 disposed at the free end of the second locking portion 42 and a second connecting portion 44 connecting the second protrusion 43 and the second base 41. The second protrusion 43, the second connecting portion 44, and the second base 41 enclose a second locking cavity 6 with an opening facing distally. The second connecting portion 44 has a second guide surface 441 on its distally facing side. The projection of the second guide surface 441 onto the horizontal plane has a first preset length L in the sagittal direction. In this embodiment, the first preset length L and the... The projection of the first guide surface 341 onto the horizontal plane has a first preset length L in the sagittal direction, and the projection of the second guide surface 441 onto the coronal plane has a first preset height H in the gingival-maxillary direction. In this embodiment, the first preset height H is equal to the first preset height H of the projection of the first guide surface 341 onto the coronal plane in the gingival-maxillary direction. In some embodiments, the second guide surface 441 may be arranged in an arc shape. In other embodiments, based on satisfying that the projection of the second guide surface 441 onto the horizontal plane has the first preset length L in the sagittal direction and the projection of the second guide surface 441 onto the coronal plane has the first preset height H in the gingival-maxillary direction, the second guide surface 441 may also be arranged in an inclined plane.

[0029] Continuing the explanation, the outer contour dimension of the first protrusion 33 is smaller than the inner contour dimension of the second locking cavity 6, and the outer contour dimension of the second protrusion is smaller than the inner contour dimension of the first locking cavity 5. This dimensional setting allows the first protrusion 33 to have a certain amount of room to move within the second locking cavity 6, and the second protrusion 43 to have a certain amount of room to move within the first locking cavity 5, thus providing dynamic comfort for the patient. This allows the patient's upper and lower jaws to move within a preset range after wearing the device, such as during involuntary oral movements at night. In particular, as described in the background art, snoring patients often use mouth breathing to solve the problem of insufficient breathing. For these patients, it is not possible to immediately correct their mouth breathing habits. If they cannot move their mouths at night, it may affect their sleep quality, such as waking up gasping for air.

[0030] Specifically, during wear, the second protrusion 43 can slide along the first guide surface 341, causing the second guide surface 441 to slide relative to the first protrusion 33. Since both the first guide surface 341 and the second guide surface 441 have a first preset length L in the sagittal direction, the second protrusion 43 and the first protrusion 33 can have a certain amount of space in the sagittal direction when sliding relative to their respective guide surfaces. Similarly, since both the first guide surface 341 and the second guide surface 441 have a first preset height H in the gingival-maxillary direction, the second protrusion 43 and the first protrusion 33 can also have a certain amount of space in the gingival-maxillary direction when sliding relative to their respective guide surfaces. Of course, it should be noted that when the first protrusion 33 and the second protrusion 43 move within the preset range, specifically, when sliding upwards along the gingiva within the range of the second preset height H1, and when sliding upwards along the mesiodistal axis within the range of the second preset length L1, the relative positional relationship of the upper and lower jaws is sufficient to open the airway and suppress snoring. Moving within the preset range allows the patient to open their mouth, and during wear, the patient can gradually adapt to the forward movement of the mandible, thereby improving patient comfort. After wearing, the first protrusion 33 is housed within the second locking cavity 6, with at least a portion of the surface of the first protrusion 33 facing the mesial side abutting against the second guide surface 441. The second protrusion 43 is housed within the first locking cavity 5, with at least a portion of the surface of the second protrusion 43 facing the distal side abutting against the first guide surface 341.

[0031] Furthermore, the placement of the first base 31 and the second base 41 is described. To ensure sufficient support area between the first base 31 and the first shell-shaped body 1, and between the second base 41 and the second shell-shaped body 2, thereby guaranteeing the reliable installation of the first repositioning jaw element 3 and the second repositioning jaw element 4, in this application, the first base 31 and the second base 41 respectively cover at least 2 / 3 of the lateral width of one tooth in their corresponding posterior tooth region in the mesiodistal direction. For example, as... Figure 1 As shown, the first base 31 is positioned on the maxillary tooth 6, and its mesiodistal length is approximately 2 / 3 of the mesiodistal lateral width of the tooth 6. It can be understood that the mesiodistal length of the first base 31 can also cover the entire mesiodistal width of the tooth 6; it can also extend to the lateral side of the adjacent tooth 5. Clinically, personalized selection is possible while meeting support strength and comfort requirements. Again, see... Figure 1 As shown, the second base 41 is disposed on the mandibular tooth 6, and its mesiodistal length is approximately 2 / 3 of the mesiodistal lateral width of the tooth 6. It can be understood that the mesiodistal length of the second base 41 can also cover the entire mesiodistal width of the tooth 6, or extend to the lateral side of the adjacent tooth 5. In clinical practice, personalized selection can be made while meeting the requirements of support strength and comfort.

[0032] Regarding the choice of placement, it is preferable that the distal ends of both the first repositioning occlusal element 3 and the second repositioning occlusal element 4 do not exceed the mesial end of the second-to-last tooth position in the patient's posterior tooth region. Considering that the most common and mature manufacturing process for invisible aligners is the thermoforming process, due to the limitations of this process, when the first repositioning occlusal element 3 and the second repositioning occlusal element 4 are placed in the last tooth position, the dental film on the gingival side of the first repositioning occlusal element 3 and the second repositioning occlusal element 4 will be significantly wrinkled and deformed, which is not conducive to film removal. Of course, if it is not limited to the thermoforming process, for example, when using 3D printing, there is no problem with film removal, the first repositioning occlusal element 3 and the second repositioning occlusal element 4 can also be placed on the lateral surface of the last tooth position.

[0033] For further explanation, please refer to [link / reference]. Figure 5 As shown, the first preset height H satisfies the following condition: when the second protrusion 43 slides along the first guide surface 341 upwards towards the gingiva to one end of the first guide surface 341 near the first protrusion 33, the gap between the incisal edges of the maxillary and mandibular anterior teeth in the upwards gingiva is within a preset gap H2. For example, in some embodiments, the preset gap H2 ranges from 0 to 5 mm. This setting effectively prevents excessive open bite or discomfort caused by temporomandibular joint dislocation. On the other hand, the preset gap H2 ensures airflow in the anterior teeth region, maintaining airway patency. As mentioned in the background art, snoring patients often breathe through their mouths at night to maintain airflow and ensure unobstructed breathing. This preset gap H2 setting is of greater value for patients who breathe through their mouths at night and are not accustomed to breathing with their mouths closed, and is more conducive to ensuring the effectiveness of treatment.

[0034] To further explain, in order to improve the fit stability between the first repositioning jaw element 3 and the second repositioning jaw element 4, please refer to... Figure 6 As shown, the lower surface 331 of the first protrusion 33 facing the opposing jaw and the upper surface 412 of the second base 41 facing the opposing jaw are a set of surfaces with matched contours. When in contact, the lower surface 331 of the first protrusion 33 facing the opposing jaw and the upper surface 412 of the second base 41 facing the opposing jaw are in surface contact. In this embodiment, the lower surface 331 of the first protrusion 33 facing the opposing jaw and the upper surface 412 of the second base 41 facing the opposing jaw are nearly planar. This surface contact design reduces localized wear at the contact points, which is beneficial for achieving the corrective effect. Furthermore, surface contact reduces the discomfort that may result from point or line contact.

[0035] In other embodiments, the upper surface 431 of the second protrusion 43 facing the opposing jaw and the lower surface 312 of the first base 31 facing the opposing jaw are a set of surfaces with matched contours, and the upper surface 431 of the second protrusion 43 facing the opposing jaw and the lower surface 312 of the first base 31 facing the opposing jaw are in surface contact when they come into contact. Similarly, the fitting stability between the first repositioning jaw element 3 and the second repositioning jaw element 4 can also be improved.

[0036] It is understood that, more preferably, the following conditions are simultaneously met: the lower surface 331 of the first protrusion 33 facing the opposing jaw and the upper surface 412 of the second base 41 facing the opposing jaw are a set of surfaces with matching contours, and the lower surface 331 of the first protrusion 33 facing the opposing jaw and the upper surface 412 of the second base 41 facing the opposing jaw are in surface contact when they come into contact; and the upper surface 431 of the second protrusion 43 facing the opposing jaw and the lower surface 312 of the first base 31 facing the opposing jaw are a set of surfaces with matching contours, and the upper surface 431 of the second protrusion 43 facing the opposing jaw and the lower surface 312 of the first base 31 facing the opposing jaw are in surface contact when they come into contact; in this case, the engagement stability of the first repositioning jaw element 3 and the second repositioning jaw element 4 is better, thereby ensuring the stable and reliable anti-snoring function of the shell-shaped dental instrument 100.

[0037] Furthermore, please refer to [the relevant documentation / reference]. Figure 7 As shown, for patients with nocturnal mouth breathing, a first occlusal pad 11 protruding towards the opposing jaw can be provided on the occlusal surface of at least one tooth in the posterior tooth region on both sides of the first shell-shaped body 1. The protrusion height of the first occlusal pad 11 is used to open the anterior tooth region of the patient's upper and lower jaws to a first target height D1. This first target height D1 allows some air to enter the anterior tooth region, avoiding discomfort caused by the patient's inability to adapt to mouth breathing. Moreover, the protrusion height of the first occlusal pad 11 can be adjusted according to the patient's specific situation to achieve personalized treatment. Preferably, please refer to [reference needed]. Figure 8As shown, the surface of the first jaw pad 11 facing the opposing jaw may also be provided with a structure that matches the occlusal surface of the opposing jaw, so as to make the occlusion more stable.

[0038] Furthermore, when the first shell-shaped body 1 is provided with the first jaw pad 11, the side of the first repositioning jaw element 3 near the tooth and the side of the first jaw pad 11 near the first repositioning jaw element 3 are adjacent to each other; it should be noted that the adjacent arrangement here means that at least part of the first jaw pad 11 covers the same tooth position as the first repositioning jaw element 3, for example Figure 7 and Figure 8 In this design, the first repositioning jaw element 3 is disposed on the buccal side corresponding to the 6th tooth of the maxilla, and the first jaw pad 11 is disposed on the occlusal surface of the 5th to 7th teeth of the maxilla, both covering the same 6th tooth. Through the adjacent design, the force guiding the mandible forward is transmitted from the first locking part 32 to the first jaw pad 11, reducing the deformation of the shell-shaped dental instrument 100.

[0039] It is understandable that the first jaw pad 11 is designed to open up the gap in the patient's anterior teeth area. Therefore, it is also possible for the first jaw pad 11 not to be installed with the first repositioning jaw element 3, for example... Figure 9 As shown, the first repositioning jaw element 3 is disposed on the buccal side corresponding to the 6th tooth of the maxilla, and the first jaw pad 11 is disposed on the occlusal surface of the 4th and 5th teeth of the maxilla, without covering the same tooth position.

[0040] For further explanation, please refer to [link / reference]. Figure 10 and Figure 11 As shown, when the first shell-shaped body 1 is provided with the first jaw pad 11, a first transition portion 35 is also provided between the side of the first repositioning jaw element 3 near the tooth and the side of the first jaw pad 11 near the first repositioning jaw element 3. The first transition portion 35 is supported on the occlusal surface of the tooth covered by the first repositioning jaw element 3. The design of the first transition portion 35 can support the gingival-occlusal force on the first repositioning jaw element 3 and the first jaw pad 11 on the tooth covered by the first transition portion 35, thereby improving the integrity and mechanical strength of the shell-shaped dental instrument 100.

[0041] Furthermore, to enhance the mechanical strength of the first transition portion 35 and thereby extend the service life of the shell-shaped dental instrument 100, this application also provides a reinforcing ridge 7 on the first transition portion 35 to strengthen its mechanical strength. The reinforcing ridge 7 is a plurality of grooved or protruding structures formed by the first transition portion 35 extending inward or outward towards the distal or proximal tooth side, along the mesiodistal or buccal-lingual direction. For example... Figure 11As shown, the reinforcing ridge 7 is formed by the first transition portion 35 protruding outward in a direction away from the tooth 200, and is four protruding structures extending in the mesiodistal direction; the reinforcing ridge 7 can also be a number of outwardly protruding block structures evenly distributed in the mesiodistal direction; similarly, it can also be understood that the reinforcing ridge 7 can also be a number of inwardly concave structures formed by the first transition portion 35 in the direction near the tooth; the inwardly concave structures can also extend in the buccal-lingual direction. In short, the reinforcing ridge 7 that can enhance the mechanical strength of the first transition portion 35 can be flexibly set, and this application does not list them all.

[0042] For further explanation, please refer to [link / reference]. Figure 12 As shown, in order to enhance the mechanical strength of the first repositioning jaw element 3 and the second repositioning jaw element 4, the side surfaces of the first repositioning jaw element 3 and the second repositioning jaw element 4 are also provided with reinforcing ridges 7 for enhancing the mechanical strength of the first repositioning jaw element 3 and the second repositioning jaw element 4. The reinforcing ridges 7 are a plurality of groove structures or protrusion structures extending along the gingival direction formed by the concave or convex side surfaces of the first repositioning jaw element 3 and the second repositioning jaw element 4.

[0043] More preferably, to enhance the mechanical strength of the first jaw pad 11, the surface of the first jaw pad 11 is also provided with reinforcing ridges 7 for strengthening the mechanical strength of the first jaw pad 11. The reinforcing ridges 7 are a plurality of groove structures or protrusion structures extending along the gingival direction formed by the concave or convex surface of the first jaw pad 11.

[0044] The reinforcement ridge 7 is configured and formed in a manner similar to the reinforcement ridge 7 on the first transition portion 35, and will not be described again here. By configuring the reinforcement ridge 7, the mechanical strength of the first repositioning jaw element 3, the second repositioning jaw element 4, and the first jaw pad 11 is further enhanced, ensuring the mechanical strength of each element during the process of guiding the mandible forward, thereby extending the service life of the shell-shaped dental instrument 100. Example

[0045] To achieve the purpose of this invention, this application also provides a shell-shaped dental instrument 100, please refer to the following: Figure 13 and Figure 14As shown. The difference between this embodiment and Embodiment 1 is that the occlusal height of the patient's upper and lower anterior teeth is achieved by setting a second occlusal pad 21 in the lower jaw. Specifically, at least one tooth in the occlusal surface of the posterior teeth on both sides of the second shell-shaped body 2 is provided with a second occlusal pad 21 protruding towards the opposing jaw. The protrusion height of the second occlusal pad 21 is used to open the anterior teeth of the patient's upper and lower jaws to a second target height D2. The protrusion height of the second occlusal pad 21 is used to open the anterior teeth of the patient's upper and lower jaws to the second target height D2, which allows some air to enter the anterior teeth area, avoiding the discomfort caused by the patient's inability to adapt to closed-mouth breathing. Moreover, the protrusion height of the second occlusal pad 21 can be adjusted according to the patient's specific situation to achieve personalized treatment.

[0046] Furthermore, when the second shell-shaped body 2 is provided with the second jaw pad 21, the side of the second repositioning jaw element 4 near the tooth and the side of the second jaw pad 21 near the second repositioning jaw element 4 are adjacent to each other. It should be noted that this adjacent arrangement means that at least a portion of the second jaw pad 21 covers the same tooth position as the second repositioning jaw element 4, for example... Figure 13 and Figure 14 In this design, the second repositioning jaw element 4 is positioned on the buccal side corresponding to the sixth tooth of the mandible, and the second jaw pad 21 is positioned on the occlusal surface of the fifth to seventh teeth of the mandible, both covering the same sixth tooth. Through an adjacent design, the force guiding the mandible forward is transmitted from the second locking part 42 to the second jaw pad 21, reducing deformation of the shell-shaped dental instrument 100.

[0047] Furthermore, when the second shell-shaped body 2 is provided with the second occlusal pad 21, a second transition portion is also provided between the side of the second repositioning occlusal element 4 near the tooth and the side of the second occlusal pad 21 near the second repositioning occlusal element 4. The second transition portion supports the occlusal surface of the tooth covered by the second repositioning occlusal element 4. The design of the second transition portion allows the gingival-occlusal force on the second repositioning occlusal element 4 and the second occlusal pad 21 to be supported by the tooth covered by the second transition portion, thereby improving the overall integrity and mechanical strength of the shell-shaped dental instrument 100.

[0048] Furthermore, in order to enhance the mechanical strength of the second transition portion and thereby extend the service life of the shell-shaped dental instrument 100, this application also provides a reinforcing ridge on the second transition portion to enhance the mechanical strength of the second transition portion. The reinforcing ridge is a plurality of groove structures or protrusion structures formed by the second transition portion concave or convex inward toward the distal or proximal tooth side, extending in the mesiodistal direction or buccal-lingual direction.

[0049] Furthermore, for example Figure 14As shown, the side surface of the second repositioning jaw element 4 is also provided with a reinforcing ridge 7 for enhancing the mechanical strength of the second repositioning jaw element 4. The reinforcing ridge 7 is a plurality of groove structures or protrusion structures extending along the gingival direction formed by the concave or convex side surface of the second repositioning jaw element 4.

[0050] A reinforcing ridge 7 can also be provided on the surface of the second jaw pad 21 to enhance its mechanical strength. The reinforcing ridge 7 is a plurality of groove structures or protrusion structures extending along the gingival direction formed by the concave or convex surface of the second jaw pad 21. By providing the reinforcing ridge 7, the mechanical strength of the second repositioning jaw element 4 and the second jaw pad 21 is further enhanced, thereby extending the service life of the shell-shaped dental instrument 100.

[0051] It is understood that reinforcing ridges 7 can be provided only on the second repositioning jaw element 4 or only on the second jaw pad 21, both of which can enhance the mechanical strength of the shell-shaped dental instrument 100 and thus ensure its service life.

[0052] The other technical solutions in this embodiment are the same as those in Embodiment 1. They can be used in conjunction with the technical solutions in this embodiment if they do not conflict with this embodiment. They will not be described again here. Example

[0053] To achieve the purpose of this invention, this application also provides a shell-shaped dental instrument 100, please refer to the following: Figure 15 and Figure 16 As shown. The only difference between this embodiment and Embodiment 1 is that the occlusal height of the patient's upper and lower anterior teeth is achieved by setting a third occlusal pad 12 and a fourth occlusal pad 22 on the upper and lower jaws respectively. Specifically, a third occlusal pad 12 protruding towards the opposing jaw is provided on the occlusal surface of the two posterior teeth of the first shell-shaped body 1, and a fourth occlusal pad 22 protruding towards the opposing jaw is provided on the occlusal surface of the two posterior teeth of the second shell-shaped body 2 at the position corresponding to the third occlusal pad 12. When set up in this way, the top surface of the third occlusal pad 12 facing the opposing jaw should occlude with the top surface of the fourth occlusal pad 22 facing the opposing jaw. The total height of the protrusions of the third occlusal pad 12 and the fourth occlusal pad 22 is used to open the anterior teeth of the patient's upper and lower jaws to the third target height D3.

[0054] It is understood that, in order to enhance the mechanical strength of the shell-shaped dental instrument 100 described in this embodiment, reinforcing ridges 7 extending along the gingival direction can also be provided on the surfaces of the third jaw pad 12, the fourth jaw pad 22, or the first repositioning jaw element 3 and the second repositioning jaw element 4, for example... Figure 16The reinforcing ridges 7 shown are disposed on the side surfaces of the third jaw pad 12 and the fourth jaw pad 22. The arrangement and formation of the reinforcing ridges 7 are the same as those in Embodiment 1, and will not be repeated here.

[0055] The other technical solutions in this embodiment are the same as those in Embodiment 1. They can be used in conjunction with the technical solutions in this embodiment if they do not conflict with this embodiment. They will not be described again here. Example

[0056] To achieve the objective of this invention, this application also provides a dental orthodontic system 1000, comprising multiple sets of shell-shaped dental instruments. The multiple sets of shell-shaped dental instruments include at least two sets of shell-shaped dental instruments 100 as described above. The first or second occlusal pads in the at least two sets of shell-shaped dental instruments extend towards the opposing jaw at different heights along the gingival-occlusal direction. During the orthodontic process, the height D4 of the opening of the patient's upper and lower anterior teeth region by the later set of shell-shaped dental instruments is less than the height D5 of the opening of the patient's upper and lower anterior teeth region by the earlier set of shell-shaped dental instruments. Please refer to [reference needed]. Figure 17 As shown, the height of the anterior teeth region of the patient's upper and lower jaws is achieved by placing a first occlusal pad 11 in the upper jaw. By gradually adjusting the height of the first occlusal pad, a gradual reduction in the height of the anterior teeth region of the patient's upper and lower jaws is achieved. For example, starting from a higher anterior teeth region opening height D5, after a period of orthodontic treatment, the patient adapts to a higher anterior teeth region opening height D4. After another period of orthodontic treatment, the patient gradually adapts to closed-mouth breathing, and the anterior teeth region does not need to be opened. This provides the patient with a gradual adaptation process, gradually changing their mouth breathing habits. When the patient is accustomed to closed-mouth breathing, there is no need for the design amount of height adjustment in the anterior teeth region of the upper and lower jaws. This gradual adjustment is more acceptable to the patient, and the patient's comfort will also be improved.

[0057] It is understood that, in other embodiments, the height of the opening of the anterior teeth region of the patient's upper and lower jaws in the orthodontic system 1000 can also be achieved by the second occlusal pad in Embodiment 2 or the third and fourth occlusal pads in Embodiment 3.

[0058] It should be noted that the above embodiments can be freely combined as needed to form different new implementation schemes without causing contradictions. All implementation schemes formed by such combinations are within the protection scope of this application. In order to save space in the application text, they will not be described in detail here.

[0059] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the inventive principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.

[0060] Similarly, the above descriptions are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
