Description

Technical Field

[0001] The utility model relates to the field of medical instruments, more specifically to the field of oral appliances, and in particular to a dental instrument for stopping snoring. Background Art

[0002] Snoring is a common sleeping phenomenon. Up to now, most people still think that snoring is commonplace and do not take it seriously. Some people even regard snoring as a sign of good sleep. In fact, snoring is the enemy of health. Snoring can lead to daytime sleepiness, fatigue, inattention, headache, decreased work ability, etc. Severe snoring is often accompanied by sleep apnea syndrome. Snoring can even cause repeated pauses in breathing during sleep, resulting in severe hypoxia of the brain and blood, forming hypoxemia, and inducing high blood pressure, cerebrocardia, arrhythmia, myocardial infarction, angina pectoris, etc., seriously affecting the patient's health.

[0003] There are many reasons for snoring, most of which are caused by airway obstruction. The nasal cavity and oral cavity are connected to the airway. When a person is asleep, the airway tissue may collapse due to muscle relaxation, mandibular retraction, and tongue falling back, causing airway obstruction. Especially for obese people, their airways are usually narrower, which makes them more prone to airway obstruction. One way to open the airway is to stretch the mandible forward to increase the muscle tension of the throat, tongue and soft palate, thereby opening the airway that collapses due to muscle relaxation during sleep. Therefore, the way to stop snoring caused by this reason is to pull the mandible forward to the ideal position to open the airway.

[0004] In recent years, in the field of orthodontics, invisible shell-shaped dental appliances have become more and more popular because of their advantages such as beauty and convenience when worn. Various orthodontic manufacturers have also tried to combine anti-snoring appliances with invisible shell-shaped dental appliances. For example, a mounting portion is provided in the area of ​​the upper jaw near the front teeth of the shell-shaped dental appliance, and a rigid connector is provided in the area of ​​the lower jaw near the back teeth of the shell-shaped dental appliance. When worn, the connector is connected to the mounting portion so that the lower jaw is kept in a forward position, thereby opening the airway to suppress snoring. However, although the existing anti-snoring devices used in combination with invisible shell-shaped dental appliances can suppress snoring, their anti-snoring connectors are mostly rigid parts. When the rigid parts are connected to the maxillary shell-shaped dental appliances, the patient's lower jaw is over-stretched forward due to its rigid characteristics, causing severe discomfort to the patient. The anti-snoring device is mostly worn before sleep. This discomfort makes the patient "daunted" after wearing it once, and even affects the patient's sleep process and sleep quality, and ultimately leads to a greatly reduced willingness of the patient to wear it again, thereby failing to achieve the therapeutic purpose of suppressing snoring.

[0005] Therefore, it is necessary to provide a snoring stopper combined with an invisible dental device, which can not only suppress snoring but also improve the comfort of the patient. Utility Model Content

[0006] The technical problem solved by the utility model is to overcome the defects of the prior art and provide a dental device for stopping snoring, which can not only combine the advantages of invisible dental devices in terms of beauty and comfort, but also improve the comfort and wearing willingness of patients, thereby achieving the therapeutic purpose of stopping snoring.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A dental device for stopping snoring, comprising a maxillary shell-shaped dental device worn on the patient's maxillary dentition, a mandibular shell-shaped dental device worn on the patient's mandibular dentition, a first mounting portion arranged on the buccal side of the maxillary shell-shaped dental device near the front teeth, and a connecting piece arranged on the buccal side of the mandibular shell-shaped dental device near the posterior teeth; wherein the first mounting portion comprises a convex column protruding away from the buccal surface of the maxillary shell-shaped dental device; the connecting piece comprises a hook portion, an elastic portion, and a second mounting portion which are sequentially connected and hooked with the first mounting portion on the same side; the connecting piece is movably connected to the buccal side of the mandibular shell-shaped dental device through the second mounting portion; the hook portion and the convex column hook the patient's mandible to move sagittally forward to a preset position to open the patient's airway, thereby suppressing the patient's snoring. The design of the elastic part allows the elastic part to be elastically deformed due to the force along the long axis of the connecting part when the connecting part is hooked on the protruding column. It is precisely because of the elastic deformation that the connecting part has a certain buffering effect when the connecting part is hooked on the protruding column, and will not cause the patient's mandible to be excessively pulled forward in the sagittal direction, and will not affect the patient's comfort when wearing it, thereby improving the patient's willingness to wear it, thereby facilitating the therapeutic purpose of suppressing snoring. On the other hand, when the positions of the first mounting part and the second mounting part remain unchanged, when the elastic part is stretched to different distances in the long axis direction of the connecting part, the sagittal forward distance of the mandible that can be maintained and stabilized by the connecting part after being hooked is also different, that is, the dental device for stopping snoring of the present application can be applied to different patients, or the same patient can adjust the preset position that best suits him when trying on the dental device for stopping snoring of the present application, that is, it can open the airway, suppress snoring, and keep the mandible at a preset position that makes him comfortable.

[0009] Preferably, the elastic deformation size range of the elastic portion along the long axis direction of the connecting member is 1 mm-5 mm.

[0010] Preferably, the connecting member rotates around the normal axis of the buccal side surface where the second mounting portion is located. Such a structural design facilitates the hooking and disengagement of the hooking portion of the connecting member and the protruding column.

[0011] Preferably, the hooking portion includes a hook portion hooked with the first mounting portion and a straight rod portion arranged adjacent to the hook portion, and the hook portion is an open structure with an opening toward the posterior tooth area. Such an open structure design makes it convenient for the hook portion to be hooked, and the rearward opening design makes it difficult for the hook portion to fall off the boss, which is safer and more reliable.

[0012] Preferably, the second mounting portion includes an outer sleeve, the elastic portion is arranged in the outer sleeve, and the end of the elastic portion away from the hook portion is arranged on the bottom wall of the outer sleeve away from the hook portion, and the other end of the elastic portion is arranged at the end of the straight rod portion away from the hook portion; wherein, the straight rod portion is at least partially accommodated in the outer sleeve. The elastic portion is arranged in the outer sleeve, which can prevent the elastic portion from pinching the buccal muscles of the patient during the stretching and retraction process, thereby improving the safety of use; and the part of the straight rod portion accommodated in the outer sleeve can play a guiding role in the long axis direction of the connecting member, so that the elastic portion can always move along the long axis direction of the connecting member.

[0013] Preferably, the difference between the outer contour dimension of the part of the straight rod portion accommodated in the outer sleeve and the inner contour dimension of the outer sleeve is in the range of 0.1 mm to 0.5 mm.

[0014] Preferably, the inner side wall of the outer sleeve portion corresponding to the part of the straight rod portion accommodated in the outer sleeve is provided with a limiting portion, and the limiting portion is provided along the inner side wall of the outer sleeve and protrudes toward the straight rod portion. The limiting portion is designed to effectively guide the elastic portion.

[0015] Preferably, the distance from the end of the limiting portion away from the opening end of the outer sleeve to the bottom wall of the outer sleeve is greater than or equal to the maximum elastic deformation dimension of the elastic portion along the long axis direction of the outer sleeve. The limiting portion is designed in such a size to ensure that the limiting portion does not hinder the tensile deformation range of the elastic portion.

[0016] Preferably, the limiting portion is continuously arranged along the circumference of the inner side wall of the outer sleeve, or the limiting portion is multiple and is spaced and symmetrically arranged along the inner side wall of the outer sleeve.

[0017] Preferably, the height of the protruding column is in the range of 3mm-5mm.

[0018] Preferably, the first mounting portion further comprises a mounting cap, the mounting cap is formed by extending from the free end of the boss to all sides and has a smooth edge, and the outer contour of the mounting cap is larger than the outer contour of the first mounting portion. The mounting cap is designed so that after the hook is hooked on the boss, it can be stably maintained between the mounting cap and the buccal side of the maxillary shell-shaped dental appliance and is not easy to fall off.

[0019] Preferably, the end of the straight rod away from the hook is further provided with a scale, and the value of the scale gradually decreases from the end of the straight rod away from the hook to the end adjacent to the hook. The dental device for stopping snoring of the present application can adapt to different patients within a certain range, or the same patient can also try and fix the most suitable length for themselves; and the scale is provided at the end of the straight rod away from the hook, which is more conducive to judging the range of the length of the connecting piece required by the patient to whom the dental device for stopping snoring can be applied, or the same patient can further identify the length of the connecting piece that best suits him.

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the various embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in each embodiment of the utility model, many technical details are proposed in order to enable readers to better understand the utility model. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection of the utility model can also be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the utility model.

[0031] Directional terms such as "upper", "lower", "left", and "right" used in the description herein are directions in the drawings and do not refer to special limitations. Unless otherwise specified and limited, the term "connection" in this article should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be directly connected or indirectly connected through an intermediate medium.

[0032] The "posterior tooth area" mentioned in each embodiment of the present invention is defined according to the classification of teeth in the second edition of "Introduction to Stomatology" published by Peking University Medical Press, pages 36-38, including premolars and molars, which are teeth 4-8 in the FDI notation, and teeth 1-3 in the anterior tooth area in the FDI notation. The teeth in the anterior tooth area include central incisors, lateral incisors and canines.

[0033] As can be seen from the background technology, although orthodontic manufacturers have tried to combine anti-snoring devices and invisible shell-shaped dental instruments, the anti-snoring connecting parts are mostly rigid parts. When the rigid parts are connected to the maxillary shell-shaped dental instruments, the patient's lower jaw is over-stretched forward due to its rigid characteristics, causing serious discomfort to the patient. Anti-snoring devices are mostly worn before going to bed. This discomfort makes patients "daunted" by wearing them after wearing them once, and even affects the patient's sleeping process and sleep quality, ultimately resulting in a much lower willingness for patients to wear them again, thereby failing to achieve the therapeutic purpose of suppressing snoring.

[0034] Based on this, the inventor proposes a dental device for stopping snoring, which can combine the advantages of invisible dental devices in terms of beauty and comfort, and can also improve the patient's comfort and willingness to wear, thereby achieving the therapeutic purpose of stopping snoring. The dental device for stopping snoring of the present application applies a sagittal forward force to the mandible, and keeps and stabilizes the position of the patient's mandible at a preset position far enough forward to open the airway, thereby achieving the purpose of stopping snoring. It comprises a maxillary shell-shaped dental instrument worn on the patient's maxillary dentition, a mandibular shell-shaped dental instrument worn on the patient's mandibular dentition, a first mounting portion arranged on the buccal side of the maxillary shell-shaped dental instrument close to the front teeth, and a connecting piece arranged on the buccal side of the mandibular shell-shaped dental instrument close to the posterior teeth; wherein the first mounting portion comprises a convex column protruding away from the buccal surface of the maxillary shell-shaped dental instrument; the connecting piece comprises a hooking portion, an elastic portion, and a second mounting portion which are sequentially connected and hooked with the first mounting portion on the same side; the connecting piece is movably connected to the buccal side of the mandibular shell-shaped dental instrument through the second mounting portion; the hooking portion and the convex column hook the patient's mandible to move sagittally forward to a preset position to open the patient's airway, thereby suppressing the patient's snoring.

[0035] Please see Figure 1 and Figure 2As shown, the dental device 100 for stopping snoring of the present application comprises a maxillary shell-shaped dental device 1 worn on the patient's maxillary dentition, a mandibular shell-shaped dental device 2 worn on the patient's mandibular dentition, a first mounting portion 3 disposed on the buccal side of the maxillary shell-shaped dental device 1 near the front teeth, and a connecting piece 4 disposed on the buccal side of the mandibular shell-shaped dental device 2 near the posterior teeth. Usually, the first mounting portion 3 is disposed on both sides of the buccal side of the maxillary shell-shaped dental device 1, and the connecting piece 4 is disposed on both sides of the buccal side of the mandibular shell-shaped dental device 2; further, the first mounting portion 3 and the connecting piece 4 are symmetrically disposed on both sides of the buccal side of the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2, respectively, so that the left and right mandibles of the patient are subjected to an equal sagittal forward force, thereby improving the patient's comfort. The maxillary shell-shaped dental instrument 1 includes a plurality of cavities arranged in a U shape for accommodating a plurality of teeth, and the geometry of the cavities matches the maxillary dentition; the mandibular shell-shaped dental instrument 2 includes a plurality of cavities arranged in a U shape for accommodating a plurality of teeth, and the geometry of the cavities matches the mandibular dentition. The first mounting portion 3 includes a convex column 31 protruding away from the buccal surface of the maxillary shell-shaped dental instrument 1, which can be formed integrally with the maxillary shell-shaped dental instrument 1, or the convex column 31 can be manufactured separately and then installed on the buccal side of the maxillary shell-shaped dental instrument 1 near the front teeth by bonding or welding; the connecting member 4 includes a hooking portion 41, an elastic portion 42 and a second mounting portion 43 which are sequentially connected, the hooking portion 41 is hooked with the first mounting portion 3 on the same side, and the connecting member 4 is movably connected to the buccal side of the mandibular shell-shaped dental instrument 2 through the second mounting portion 43. The first mounting portion 3 is arranged at a position close to the front teeth of the maxillary shell-shaped dental appliance 1, and the connecting member 4 is arranged at a position close to the back teeth of the mandibular shell-shaped dental appliance 2. In this way, after the first mounting portion 3 and the connecting member 4 are hooked by the hooking portion 41 and the protruding column 31, the patient's mandible can be subjected to a sagittal forward force, so that the mandible moves sagittally forward to a preset position to open the patient's airway, thereby suppressing the patient's snoring.

[0036] When wearing the dental device 100 for stopping snoring of the present application, usually, the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2 are worn separately first; wherein, if the boss 31 and the maxillary shell-shaped dental device 1 are manufactured separately, the boss 31 can be installed outside the mouth first, and then the maxillary shell-shaped dental device 1 is worn on the patient's maxillary dentition; since the connecting member 4 is arranged at a position of the mandibular shell-shaped dental device 2 close to the posterior teeth, and the space in the oral cavity is relatively small, therefore, for the convenience of operation, the connecting member 4 can also be connected to the mandibular shell-shaped dental device 2 outside the mouth first, and then the mandibular shell-shaped dental device 2 is worn on the patient's mandibular dentition; then, the hooking portion 41 is hooked on the boss 31 to move the patient's mandible sagittally forward to a preset position, that is, to move the patient's mandible sagittally forward to a position that can open its airway, and to maintain and stabilize the patient's mandible at the preset position, thereby suppressing the patient's snoring. For different patients, in order to achieve the purpose of suppressing their snoring, the distance of moving the mandible sagittally forward required to open the airway is not the same. Therefore, when designing the dental device 100 for stopping snoring, an important step is to design and determine the setting position of the first mounting portion 3 on the maxillary shell-shaped dental device 1 and the setting position of the connecting member 4 on the mandibular shell-shaped dental device 2 according to the personalized characteristics of each patient. Usually, the preset position is designed to be the position when the patient's airway is most fully opened during sleep. Such position design and coordination are used to achieve maintaining and stabilizing the patient's mandible at the preset position, thereby opening the airway and suppressing snoring. However, during the hooking connection process of the existing snoring stopper designed in combination with the invisible shell-shaped dental instrument, that is, when the hooking portion 41 of the connecting member 4 is hooked onto the protruding column 31, the connecting member 4 only has the rigidity to maintain and stabilize the patient's mandible at the preset position after being hooked. During the hooking process, the patient's mandible will be pulled beyond its preset position for a period of time, causing strong discomfort. The snoring stopper is usually worn before going to sleep. This discomfort makes the patient "daunted" after wearing it once, and even affects the patient's sleeping process and sleep quality, and ultimately leads to a much lower willingness of the patient to wear it again, thereby failing to achieve the therapeutic purpose of suppressing snoring. Therefore, in the present application, the connecting member 4 includes an elastic portion 42, one end of the elastic portion 42 is arranged adjacent to the hook portion 41, and the other end is arranged adjacent to the second mounting portion 43, and the elastic portion 42 is elastic so that when the connecting member 4 hooks the boss 31, the elastic portion 42 undergoes elastic deformation due to the force along the long axis direction of the connecting member 4. For example, in some embodiments, the elastic portion 42 may be a spring.It is precisely because of this elastic deformation that, on the one hand, when the connecting member 4 is hooked on the protruding column 31, the connecting member 4 has a certain buffering effect, which will not cause the patient's lower jaw to be excessively pulled forward in the sagittal direction, and will not affect the patient's comfort when wearing it; on the other hand, due to the setting of the elastic portion 42, after the connecting member 4 is hooked, the patient's lower jaw can have a certain sagittal movement space, so that the pain and other discomfort caused by the patient's lower jaw being kept in a fixed position for a long time when wearing it for a long time can be avoided; therefore, the setting of the elastic portion 42 enhances the patient's willingness to wear it, which is conducive to achieving the therapeutic purpose of suppressing snoring.

[0037] In other embodiments, the elastic portion 42 is capable of being stretched and elastically deformed under the action of a force. In addition, the elastic portion 42 has a rigidity that can ensure that it can be stabilized in its deformed position after being stretched and elastically deformed. Therefore, when the positions of the first mounting portion 3 and the second mounting portion 43 remain unchanged, when the elastic portion 42 is stretched to different distances in the long axis direction of the connecting member 4, the connecting member 4 can maintain and stabilize the sagittal forward distance of the mandible at different distances after being hooked. That is, the dental device 100 for stopping snoring of the present application can be suitable for different patients, or the same patient can adjust the preset position that best suits him / her when trying on the dental device 100 for stopping snoring of the present application, that is, it can open the airway and suppress snoring, and keep the mandible at a preset position that makes him / her comfortable.

[0038] In some embodiments, please continue to see Figure 2 , and combined with Figure 3 As shown, the elastic deformation size range of the elastic portion 42 along the long axis direction X of the connecting member 4 is 1mm-5mm. Furthermore, the elastic deformation size range is preferably 2mm-3mm. Figure 2 The elastic portion 42 shown is in a state where no elastic stretching occurs, and its dimension along the long axis direction X of the connecting member 4 is L1. Figure 3The elastic portion 42 shown is in a state after being elastically stretched along the long axis direction X of the connecting member 4, and its dimension along the long axis direction X of the connecting member 4 is L2. In this embodiment, the elastic deformation dimension of the elastic portion 42 along the long axis direction X of the connecting member 4 is the difference between L2 and L1. After a large number of experiments, the inventor has designed an elastic deformation dimension range of 1mm-5mm. On the one hand, within such a dimension range, most patients can wear the dental device 100 for stopping snoring, especially when the connecting member 4 is hooked on the boss 31, which can play a sufficient cushioning role and is convenient and comfortable to wear; on the other hand, within such a dimension range, most patients can try it on and find a preset position that suits them, further improving the comfort and wearing willingness of the patients, thereby improving the treatment effect and efficiency.

[0039] In some embodiments, the connecting member 4 rotates around the normal axis of the buccal side where the second mounting portion 43 is located. Figure 4 As shown, the normal axis of the buccal side where the second mounting portion 43 is located is indicated by Z, and the buccal side where the second mounting portion 43 is located is indicated by P, and the normal axis Z is perpendicular to the buccal side P where the second mounting portion 43 is located. This design facilitates the hooking and unhooking of the hooking portion 41 of the connecting member 4 and the protruding column 31 when wearing and removing the dental device 100 for stopping snoring of the present application, and does not interfere with each other when wearing and removing the dental device 100 for stopping snoring. Please refer to Figure 1 As shown, usually, after the patient wears the maxillary shell-shaped dental instrument 1 and the mandibular shell-shaped dental instrument 2, the patient rotates the connecting member 4 in the Z-axis direction so that the hooking portion 41 of the connecting member 4 is located in front of the protruding column 31, and then closes the bite and hooks the connecting member 4 and the protruding column 31 together; if the maxillary shell-shaped dental instrument 1 and the mandibular shell-shaped dental instrument 2 are to be removed, the connecting member 4 and the protruding column 31 can be disengaged first, and the connecting member 4 can be rotated in the opposite direction to a position where there is no interference with the protruding column 31, and finally the maxillary shell-shaped dental instrument 1 and the mandibular shell-shaped dental instrument 2 are removed respectively.

[0040] In some embodiments, please continue to see Figures 1 to 3 As shown, the hooking portion 41 includes a hook portion 411 hooked with the first mounting portion 3 and a straight rod portion 412 disposed adjacent to the hook portion 411. Figure 2 and Figure 3The boundary between the hook portion 411 and the straight rod portion 412 is not obvious, and the boundary line is indicated by a dotted line, but the structural composition is not limited thereto, that is, the hook portion 411 and the straight rod portion 412 can be designed as an integral part or can be manufactured separately. The hook portion 411 is an open structure with an opening facing the posterior tooth area. The non-fully enclosed opening structure in this embodiment is conducive to the hooking of the hook portion 411 and the boss 31, and the design of the hook portion 411 with the opening facing backwards avoids the situation where the hook portion 411 falls off in the oral cavity, thereby ensuring its therapeutic effect and safety in use. Because after hooking, the patient's mandible has a sagittal forward force F1, and since the force is mutual, the connecting member 4 will be subjected to a sagittal backward force F2. Then, after the hook portion 411 and the boss 31 are hooked, the hook portion 411 has a backward force F2 relative to the boss 31. Under the action of the force, the hook portion 411 will not fall off the boss 31, which is safer and more reliable.

[0041] In some embodiments, please refer to Figure 5 As shown, the second mounting portion 43 includes an outer sleeve 431, the elastic portion 42 is arranged in the outer sleeve 431, and the end of the elastic portion 42 away from the hook portion 411 is arranged on the bottom wall of the outer sleeve 431 away from the hook portion 411, and the other end of the elastic portion 42 is arranged at the end of the straight rod portion 412 away from the hook portion 411; wherein, the straight rod portion 412 is at least partially accommodated in the outer sleeve 431. The profile of the outer sleeve 431 can be a cylinder, a square column or a prism, and the cylinder is used as an example in this application. The elastic portion 42 is arranged in the outer sleeve 431, which can prevent the elastic portion 42 from pinching the buccal muscles of the patient during the stretching and retraction process, thereby improving the safety of use. The part of the straight rod portion 412 accommodated in the outer sleeve 431 can play a guiding role in the long axis direction of the connecting member 4, so that the elastic portion 42 can always move along the long axis direction of the connecting member 4.

[0042] It should be noted that, in the present application, the connection structure feature of the second mounting portion 43 and the mandibular shell-shaped dental instrument 2 is not the focus of the invention of the present application. The connection structure can be installed in conjunction with the second mounting portion 43 to connect the connecting member 4 to the mandibular shell-shaped dental instrument 2.

[0043] In some embodiments, in order to ensure the guiding function of the part of the straight rod 412 accommodated in the outer sleeve 431, the present application defines the outer contour dimension D of the part of the straight rod 412 accommodated in the outer sleeve 431: the size difference between the outer contour dimension D of the part of the straight rod 412 accommodated in the outer sleeve 431 and the inner contour dimension D2 of the outer sleeve 431 is 0.1mm-0.5mm. Further, the size difference range is preferably 0.3mm-0.4mm. The inventor has conducted experimental research and found that the size difference range does not affect the movement of the straight rod 412 itself, and can ensure that the elastic part 42 moves effectively under the guidance of the part of the straight rod 412 accommodated in the outer sleeve 431. Generally, in this embodiment, the outer contour dimension D1 of the elastic part 42 is consistent with the outer contour dimension D of the part of the straight rod 412 accommodated in the outer sleeve 431, or the outer contour dimension D1 of the elastic part 42 is slightly smaller than the outer contour dimension D of the part of the straight rod 412 accommodated in the outer sleeve 431.

[0044] In some other embodiments, see Figures 6 to 8 As shown, when the outer contour size of the partial straight rod portion 412 accommodated in the outer sleeve 431 has a large difference in size with the inner contour size of the outer sleeve 431 and cannot be effectively guided, the present application provides a limiting portion 4311 on the inner side wall of the outer sleeve 431 portion corresponding to the partial straight rod portion 412 accommodated in the outer sleeve 431, and the limiting portion 4311 protrudes along the inner side wall of the outer sleeve 431 toward the straight rod portion 412, and is used to effectively guide the elastic portion 42. In the figure, the boundary between the limiting portion 4311 and the straight rod portion 412 is not obvious, and the boundary line is indicated by a dotted line, but the structural composition is not limited, that is, the limiting portion 4311 and the straight rod portion 412 can be designed as an integral molding, or can be manufactured separately. Further, in order to obtain a better guiding effect, the size difference between the inner contour dimension D4 of the limiting portion 4311 and the inner contour dimension D5 of the outer sleeve 431 is in the range of 0.1 mm to 0.5 mm, wherein the inner contour dimension of the limiting portion 4311 refers to the dimension between the side walls of the limiting portion 4311 facing the straight rod portion 412. Generally, in this embodiment, the outer contour dimension D3 of the elastic portion 42 is greater than the outer contour dimension D of the portion of the straight rod portion 412 accommodated in the outer sleeve 431.

[0045] In some embodiments, the distance H2 from the end of the limiting portion 4311 away from the open end of the outer sleeve 431 to the bottom wall of the outer sleeve 431 is greater than or equal to the maximum elastic deformation dimension H1 of the elastic portion 42 along the long axis direction of the outer sleeve 431. The limiting portion 4311 is designed in such a size to ensure that even when the outer contour dimension D3 of the elastic portion 42 is greater than the inner contour dimension D4 of the limiting portion 4311, the limiting portion 4311 will not hinder the tensile deformation range of the elastic portion 42.

[0046] In some embodiments, see Fig. 9 As shown, the limiting portion 4311 is continuously arranged along the circumference of the inner wall of the outer sleeve 431. At this time, the limiting portion 4311 is a hollow cylinder as a whole, and the guiding effect is better.

[0047] In other embodiments, the limiting portion 4311 is multiple and is spaced and symmetrically arranged along the inner wall of the outer sleeve 431. Fig.10 The four symmetrically arranged limit portions 4311 shown can also be arranged with other numbers of limit portions 4311, which is beneficial to saving the manufacturing materials of the limit portions and reducing the cost; and the symmetrically arranged limit portions 4311 can symmetrically guide the straight rod portion 412 on the basis of saving raw materials, and the guiding effect is better than that of the asymmetrically arranged limit portions 4311.

[0048] In some embodiments, see Fig.11 As shown, in order to ensure the stability of the connecting member 4 after connection, in the present application, the height H of the protruding column 31 is designed to be between 3mm and 5mm, with 4mm being more preferred. Such a protruding height can not only meet the hooking requirements of the hook portion 411, but also will not hurt the buccal muscles of the patient's upper jaw.

[0049] In some embodiments, the first mounting portion 3 further includes a mounting cap 32, which is formed by extending the free end of the boss 31 in all directions and has a smooth edge. The outer contour dimension D6 of the mounting cap 32 is greater than the outer contour dimension D5 of the first mounting portion 3, thereby forming a "mushroom head". The design of the mounting cap 32 allows the hook portion 411 to be stably maintained between the mounting cap 32 and the buccal side of the maxillary shell-shaped dental device 1 after being hooked on the boss 31, and is not easy to fall off. Furthermore, the mounting cap 32 can be made of a soft material so that the buccal muscles of the patient are more comfortable when in contact with it.

[0050] In some embodiments, please refer again to Figure 6As shown, the end of the straight rod 412 away from the hook 411 is also provided with a scale, and the value of the scale gradually decreases from the end of the straight rod 412 away from the hook 411 to the end adjacent to the hook 411. The distance that the dental device 100 for stopping snoring moves the patient's mandible in the sagittal direction is affected by the connection positions of the two ends of the connecting member 4 on the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2 (i.e., the position of the first mounting portion 3, and the position of the buccal side of the mandibular shell-shaped dental device 2 corresponding to the second mounting portion 43) and the length of the connecting member 4. For different patients, at least one of the connection positions of the two ends of the connecting member 4 on the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2 and the length of the connecting member 4 is different, which is relatively complicated in terms of design and production. In combination with the dental device 100 for stopping snoring of the present application, for the convenience of design and production, the connection positions of the two ends of the connecting member 4 on the maxillary shell-shaped dental device 1 and the mandibular shell-shaped dental device 2 can be uniformly designed. For example, the tooth surface No. 4 of the maxillary shell-shaped dental device 1 can be determined as the setting position of the first mounting portion 3, and the tooth No. 5 of the mandibular shell-shaped dental device 2 can be determined as the position corresponding to the second mounting portion 43 to design the position of the connecting structure that cooperates with the second mounting portion 43. Because in the present application, one end of the connecting member 4 is designed with an elastic portion 42, even if the two ends of the connecting member 4 are designed according to a uniform setting position, it can still adapt to different patients within a certain range or the same patient can try on and fix the most suitable length for themselves; and a scale is set at the end of the straight rod portion 412 away from the hook portion 411, which is more conducive to judging the length range of the connecting member 4 required by the patient to whom the dental device 100 for stopping snoring can be applied or the same patient can further identify the length of the connecting member 4 that best suits him.

[0051] It should be noted that the above embodiments can be freely combined as needed to form different new implementation plans without causing any contradiction. The implementation plans formed after such combination are all within the scope of protection of this application. In order to save the length of the application text, they will not be repeated here.

[0052] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the creative principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present application.

[0053] Similarly, the above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
